　　The concept of Internet hospital sprouted in 2011, and by the end of 2015, the first Internet hospital in China — — Wuzhen Internet Hospital was established. In April 2018, the General Office of the State Council issued the Opinions on Promoting the Development of "Internet+Medical Health", which put forward the concept of Internet hospital for the first time in the document, and made it clear that Internet hospitals must rely on physical medical institutions.

　　Different from the online consultation in the past — — Taking advantage of doctors’ fragmented time for consultation, it provides services of registration, payment and report inquiry. Internet hospital refers to a one-stop service platform that relies on physical hospitals, focuses on online follow-up and routine consultation, and integrates consultation, prescription, payment and drug distribution.

　　"The Internet diagnosis and treatment of Union Medical College Hospital is not the earliest, but we strive to do our best." Qin Mingwei, director of the telemedicine center of Peking Union Medical College Hospital, said that the hospital can provide follow-up services for some patients with common diseases and chronic diseases. At present, 27 departments including cardiology, endocrinology and dermatology have been opened to support in-hospital case review, online consultation, inspection and prescription.

　　Because of the epidemic, Internet diagnosis and treatment has "fired" from the small public’s field of vision to the public’s demand. According to incomplete statistics, there are now more than 1,100 Internet hospitals in China. From online consultation, appointment and registration to providing high-quality online diagnosis and treatment services, after experiencing "more doctors" and "faster prescription", how can Internet hospitals move towards "good curative effect" and "low cost", so that ordinary people can really see the disease, see it well and afford it? Obviously, there are still several unsolved problems in front of the Internet hospital.

　　1. Can it alleviate the difficulty of seeking medical treatment?

　　"Hello, Dr. Chai, I have been eating metformin, and my blood sugar is somewhat repeated. The control is not ideal. What should I do?"

　　"Your islet function is OK. You should keep taking metformin. I’ll give you another medicine to eat with."

　　"I’m quite fond of eating, including some sweets. Can I eat fruit?"

　　"You can eat some northern fruits in moderation. Diabetes still needs to be shut up, ‘ Sugarcane is not as sweet as both ends ’ If you want to be healthy, you must learn to avoid eating, which is indeed a ‘ Pain ’ The process of … …”

　　This is the scene where Chai Xiaofeng, the attending physician of endocrinology department of Peking Union Medical College Hospital, makes a follow-up visit to Mr. Bai in Jinzhong City, Shanxi Province through the network. Mr. Bai told the reporter that with the help of his family, he hung up the number of his previous doctor by using the "Peking Union Medical College Hospital" App and successfully completed the follow-up visit. "Very patient and responsible, and the advice given is very professional!"

　　How to operate the mobile phone follow-up visit? Hospital staff clicked on the "Peking Union Medical College Hospital" App to demonstrate to reporters: before the appointment time on the day of the visit, on the home page, "I" — — Check in the "consultation record". According to the registration order, the doctor initiates the consultation invitation in the form of short message, voice or video, and the patient can reply to the information or click answer to start the consultation. The whole process is easy to operate, even for elderly patients who can’t surf the Internet, they can easily complete it with the help of their families.

　　"The speed of the development of Internet medical care first depends on the development of products." Chen Qiulin, deputy director of Health Industry Development Research Center of China Academy of Social Sciences, pointed out that this is an interactive process, and product innovation and model innovation can promote system innovation.

　　"Online doctors are mostly young and middle-aged doctors, and offline clinics are still occupied by senior professors. In this way, regular follow-up patients can no longer occupy the source of offline clinics and leave the source to those patients with incurable diseases. This is also the optimal allocation of medical resources." Qin Mingwei said that 60% of the patients in Peking Union Medical College Hospital came from outside Beijing, and the online follow-up visit also greatly saved the time cost and round-trip expenses of patients.

　　"We have also opened the online and offline outpatient service conversion appointment function." According to Qin Mingwei, the patient’s condition of online follow-up is relatively stable, and there is no need for complicated medical examination or treatment. However, if the patient’s condition is found to have changed significantly and is no longer suitable for online diagnosis and treatment, he can directly arrange an appointment for an offline clinic to avoid the trouble for patients to make appointments through other channels.

　　How to get medicine in an Internet hospital? It is understood that in September last year, the Internet medical drug distribution service of Peking Union Medical College Hospital was officially launched. In order to make the express delivery arrive more accurately, the hospital selects high-quality drug delivery contractors and signs long-term cooperation agreements. National non-medical insurance patients can enjoy the "peer-to-peer" delivery service of drugs to their homes after returning to Peking Union Medical College Hospital online, and can inquire about prescriptions and medication guidance on the mobile phone client of Peking Union Medical College Hospital. If in doubt, they can also consult with Concord pharmacists online.

　　There are hundreds of millions of patients with chronic diseases in China. The diseases are incurable and have many complications, which need long-term medication and health management to control. "I saw 25 patients in the morning according to the regulations. In fact, I often saw more than 40 patients. Half of them may be unnecessary to see. " Sun Xiaodong, deputy director of the Department of Ophthalmology of Shanghai First People’s Hospital, said that 70% ~ 80% of chronic diseases can be consulted in Internet hospitals.

　　According to Lu Qingjun, director of the Office of National Health Commission Primary Telemedicine Development Guidance Center, large hospitals have the ability of technological innovation and academic leadership. After establishing an Internet hospital and forming a mature platform, they can be shared and transferred to the primary level. "In the future, I believe that all medical institutions have the opportunity and ability to use the Internet platform to carry out Internet medical care."

　　Mao Ying, dean of Huashan Hospital of Fudan University, hopes to further rationalize the relationship between public hospitals and Internet hospitals such as third-party medical institutions, and at the same time, open the scope of practice and the autonomy of subjects and prices of Internet hospitals in public hospitals. "At present, online follow-up dispensing in public hospitals is limited to ordinary clinics, and expert clinics and special needs clinics have not been liberalized."

　　"The positioning of our Internet hospital is very clear from the beginning, that is, to achieve graded diagnosis and treatment, to leave patients at the grassroots level, and to sink high-quality medical resources to the end, to send medicines to the people at the grassroots level, to standardize management, to implement education, and to minimize medical expenses." Li Guanming, deputy secretary of the Party Committee and vice president of the Second People’s Hospital of Guangdong Province, said.

　　2. Can you achieve the effect of offline diagnosis and treatment?

　　Behind the rapid development of Internet medical care is the rigid demand for people’s livelihood. In the face of Internet hospitals, many people have questions: Can remote video see the symptoms clearly? If you don’t take a film and check your blood, can you diagnose it?

　　In fact, Internet hospitals at this stage are not "cloud consultation" but "cloud follow-up". "Many patients have already seen a doctor in a physical hospital, and all the tests that should be done have been done. On the one hand, online follow-up is to understand the progress of the disease, on the other hand, it is to prescribe drugs and adjust drugs. More patients go to ‘ Cloud ’ It is to consult a doctor’s professional opinion. If further examination or surgery is needed, the doctor will inform the patient to transfer to a physical hospital for treatment. If it is impossible to see a doctor, how to deal with it temporarily. " Shu Yongqian, director of jiangsu province hospital Cancer Center, pointed out that this kind of consultation is more like the pre-examination and triage of primary medical institutions, focusing on judging the severity of patients’ symptoms, and forming a service order of graded diagnosis and treatment with offline entity hospitals. On the Internet hospital platform, you can directly return to the clinic and issue an electronic prescription to buy drugs.

　　At present, the technical means of online diagnosis and treatment are relatively mature. Internet hospitals have made great progress in mobile ward rounds, mobile nursing, full link of monitoring equipment, remote first aid, remote consultation, medical teaching, surgical robots and remote surgery.

　　In April last year, sir run run shaw hospital cooperated with Zhejiang Unicom and Huawei Company to set up a 5G Innovation Center. By sorting out more than 2.5 million electronic medical records in the hospital, it led the development of a general clinical intelligent decision-making system, and built a medical knowledge map covering more than 600,000 ontological logical logical associations. Based on the current medical knowledge base and reasoning model, this AI reasoning engine can infer and push the symptoms, signs, medical history and examination results of patients with an accuracy rate of 90%.

　　"Now there are no technical problems in the development of Internet hospitals. The real bottleneck is how doctors really devote themselves to Internet hospitals. Internet hospitals are not ‘ Light consultation ’ Upgrade and revision. " Zhang Qiang, a well-known vascular surgery expert, suggested the establishment of internet diagnosis and treatment, from fragmented services to exclusive customized services, from no standard to full quality control.

　　Cui Yong, vice president of the China-Japan Friendship Hospital, said: "To ensure a high degree of consistency between online and offline, this also puts high demands on doctors. It is necessary to learn to use Internet technology to carry out diagnosis and treatment. " In this regard, Zhao Chengsong suggested that doctors should be trained on the Internet to improve their online diagnosis and communication skills. "Internet medical care is not exclusive to young doctors. Experienced experts should take the lead in embracing the Internet so that more patients can enjoy quality medical resources." Zhao Chengsong said.

　　National Health Commission explicitly requested that Internet diagnosis and treatment activities should not be carried out for the first-time patients, which was based on medical safety considerations. In the future, which projects can be "tested" for initial diagnosis?

　　Cui Yong believes that we can "test the water" from the field of skin diseases. "Most skin diseases can get good diagnostic information through naked eyes or simple equipment (such as dermatoscope). At present, ‘ Skin image application framework network ’ It can also achieve information exchange well and can be used for telemedicine and Internet diagnosis and treatment. " Cui Yong said.

　　"In the future, diseases that can be accurately diagnosed through intuitive information collection may be considered for online initial diagnosis." Cui Yong pointed out, however, critical illness and incurable diseases are definitely not suitable for online initial diagnosis, and diseases that need to be examined and tested generally need to go to medical institutions or third-party service institutions (provided that a mutual recognition system for examination and test results is established).

　　In this regard, Yuan Li, director of the wuhan union hospital Clinic Office, also agreed. She said that online consultation and offline consultation are not a substitute, but more are extended services before and after the hospital to reduce the economic and time burden of patients and timely inform patients of the most authoritative and most suitable popular science knowledge. At present, online consultation in wuhan union hospital is divided into two categories: health consultation and follow-up consultation. Doctors will give corresponding suggestions according to the information provided by patients, but the diagnosis, diagnosis and treatment of diseases still need offline consultation and examination.

　　3. Can online medical insurance settlement be popularized?

　　0.02 seconds to extract historical medication information, and 2 minutes to complete identity verification and medical insurance binding … … In April last year, Shandong Province’s Internet medical insurance big health service platform was launched, and key links such as medical insurance certification, follow-up check-up, online prescription, and drug delivery to home were seamlessly connected. Shandong became the first province in China to fully open and support online medical insurance settlement for Internet diagnosis and treatment.

　　Mr. Zhang from lanshan district, Linyi City became the first beneficiary. "As long as in ‘ Shandong Medical Insurance Great Health ’ After completing the medical insurance identity verification and medical insurance binding in WeChat official account, you can use medical insurance payment by choosing an Internet hospital for treatment. " Mr. Zhang is 54 years old and suffers from coronary heart disease. He usually needs to make regular follow-up visits to get medicine. "It’s so convenient now! Seeing a doctor at home can also be settled by medical insurance and delivered to the door. "

　　According to incomplete statistics, since 2015, the state and local governments have issued more than 100 policies and regulations on Internet medical care, which have gradually covered "medical — Medicine — Risk "field. In response to the issue of medical insurance reimbursement in Internet hospitals, the relevant person in charge of the National Medical Insurance Bureau said that it will improve the price formation mechanism of "Internet+medical care" services, adhere to the basic principle of reasonable price comparison between online and offline similar services, incorporate medical expenses into medical insurance, and implement online direct settlement.

　　"The insured person is designated in this overall planning area ‘ Internet plus & rsquo; The medical and drug expenses incurred by the prescription issued by the medical service follow-up visit can be paid according to the existing treatment policy of offline medical insurance. With the prescription of designated medical institutions, you can also take medicine at local designated pharmacies. " Xiong Xianjun, director of the Medical Service Management Department of the National Medical Insurance Bureau, said.

　　Lu Qingjun believes that the "internet plus" medical insurance payment policy clarifies that the "internet plus" medical service is included in the specific content of medical insurance payment, online and offline medical services are treated fairly, and priority is given to ensuring the demand for follow-up visits for chronic diseases and special diseases, and supporting the circulation of purchased prescriptions, which not only facilitates patients, but also reduces the pressure on hospitals.

　　"Internet hospitals need links of various elements. Under the premise of high-quality diagnosis and treatment services, medical services, medicines, insurance, etc., the real Internet diagnosis and treatment will appear in the cooperation and exploration between doctors and third parties. With the enhancement of patients’ willingness to pay at their own expense and the intervention of commercial insurance, Internet hospitals will have a stronger ‘ Vitality ’ 。” Zhang Qiang said.

　　Although Internet hospitals provide many conveniences for patients to seek medical treatment, the difficulty of supervision has also become a major pain point that hinders its development. The reporter noted that the third-party Internet hospital platform is characterized by "e-commerce", and the use of traffic to sell drugs has become a common model, and Internet hospitals have become Internet medicine.

　　Yinchuan is the "pioneer area" of Internet medical exploration in China. During the two sessions this year, Commissioner Ma Xiuzhen, director of Ningxia Health and Health Commission, pointed out in his proposal that drug sales revenue is an important source of profit for some commercial Internet hospitals. Due to the lack of motivation to supervise over-medication, doctors may be encouraged to prescribe more drugs, or even collude with pharmaceutical companies to promote online drug sales, leading to over-medication. At present, the regulatory authorities have not yet established a regulatory system for excessive drug use for online diagnosis and treatment, and violations have an upward trend. Therefore, it is suggested to implement "separation of medicine" online.

　　To this end, Chen Qiulin reminded that in the future, the Internet hospital supervision platform should dynamically monitor online diagnosis and treatment services, and carry out medical technology evaluation and health economics evaluation, especially for services to be included in medical insurance payment, it should monitor the changing trend of online and offline medical care and analyze its substitution and complementarity.

　　 　 　(Reporter Cui Xingyi)

　　The scenery ahead is infinite, and the footsteps are powerful. Standing in 2024, the construction of Huawei’s HarmonyOS operating system ushered in a "decisive moment". A few days ago, china securities journal reporter found that despite the enormous challenges and uncertainties, HarmonyOS’s success already has multiple favorable factors, and once it crosses the critical point, HarmonyOS will realize Huawei’s historic leap in the operating system field.

　　According to Huawei’s plan, in the fourth quarter of this year, Huawei will launch the HarmonyOS Xinghe version of the operating system, which is no longer compatible with Android. This means that HarmonyOS’s operating system will bid farewell to the early compatibility strategy and go on its own, so netizens call it "pure blood HarmonyOS". "Pure blood HarmonyOS" means that the system only supports native Applications, that is, the app needs to be rewritten, otherwise it cannot be used. Huawei’s goal this year is to have 5,000 apps supporting Pure Blood HarmonyOS, and its future goal is to have 500,000 native apps for Pure Blood HarmonyOS. Apple’s iOS and Android App are both on the order of 2 million native applications, and there is a huge gap in front of HarmonyOS.

　　Xu Zhijun, vice chairman and rotating chairman of Huawei, recently shouted at the 2024 Huawei Analyst Conference, hoping that all developers in the country would join HarmonyOS’s native application ecology as soon as possible. "Huawei has managed 5,000 applications and another 1 million applications, hoping that the whole society will develop them together."

　　Ren Zhengfei, president of Huawei, once said, "Let those who can hear the sound of guns call for gunfire". Now, HarmonyOS is facing a "decisive moment", and Huawei’s call is urgent. Can the market hear it? How do companies react? How is the development of native applications going? What is HarmonyOS’s odds in the future?

　　"Give enough money to people" to rebuild infrastructure

　　Operating system is called the soul of computer system, and there are only a few successful cases in the market, such as Windows, Apple and Android. Operating system technology is not difficult, difficult in ecology, and difficult to be accepted by the market.

　　The good news is that china securities journal reporters have learned from many interviews and investigations that based on the future prospects of HarmonyOS’s industry, Alipay, Taobao, Meituan, JD.COM, Nail, Gaode, Xiaohongshu and other head App application manufacturers have started the development of HarmonyOS native applications at the first time. Many manufacturers "give enough money to people" and work overtime to invest in development.

　　Meituan is the first Internet giant to join HarmonyOS’s native application ecology. Wang Zhiyu, executive director of HarmonyOS Xinghe Edition Meituan App Development Project, told china securities journal that in September 2023, Huawei and Meituan discussed the development of native applications in HarmonyOS, and in November 2023, the two parties signed a contract. According to the delivery schedule, internal testing will begin in March 2024 and public testing will be conducted in June.

　　Wang Zhiyu said: "The HarmonyOS Xinghe version of Meituan App was developed from scratch. Meituan urgently deployed R&D personnel in various business groups to invest in project development in November last year. We started from the research and development of the underlying infrastructure, and everyone learned while working, and the construction period was very tight."

　　It is understood that Meituan completed the core function development of HarmonyOS Xinghe Meituan App in six weeks, and ordered the first HarmonyOS Xinghe Meituan App takeaway. The first HarmonyOS Xinghe version of Meituan App covers food, hotel, medicine, take-away, flash purchase, optimization, grocery shopping and other businesses, and is currently being tested. "When users order take-out in HarmonyOS Xinghe version of Meituan App in the future, they can check the progress and details of Meituan take-out orders in time through the live window, and see the key dynamics of take-out at a glance." Wang Zhiyu said.

　　At the end of March this year, Yangguang. com was the first in the industry to complete the full version development of native applications in HarmonyOS. All the functional modules of Yangguang. com App on Apple’s iOS and Android, and HarmonyOS Xinghe Edition have achieved full coverage. Gong Xiaoou, the head of client development of Yangguang. com Technology Center, told china securities journal that in August 2023, Yangguang. com invested 20 staff members to start the development of native applications in HarmonyOS, which took nearly seven months. At the end of March this year, it was launched internally to test the HarmonyOS Xinghe version of Yangguang. com App. HarmonyOS Xinghe Edition Yangguang. com App has also completed the adaptation on terminal devices such as folding screen mobile phones and tablets.

　　Gong Xiaoou said, "Pure Blood HarmonyOS" is a brand-new ecology, and it has just started. As the national team of Internet news dissemination and an important new media platform of China Central Radio and Television Station, the earlier it joins HarmonyOS’s native application ecology, the more it can seize the opportunity, be downloaded and paid attention to by more users, and provide rich information services for more users.

　　According to Huawei, more and more partners have made breakthrough innovations. Bilibili, Xiaohongshu, Iqiyi, Himalaya, WPS Office, China Merchants Bank, Postal Savings Bank and other head applications have completed the development of the test version of HarmonyOS Xinghe App, and the products are being continuously polished.

　　WPS Office is a very basic application office software under Jinshan Office, which has a wide user base. By the end of 2023, the number of monthly active devices of WPS Office mobile version reached 330 million. Yao Dong, vice president of Jinshan Office, told china securities journal: "WPS Office is the first partner to join the native application development in HarmonyOS. We attach great importance to this cooperation and quickly set up a development team of hundreds of people. At the same time, Huawei also has resident R&D personnel to jointly develop, adjust and optimize HarmonyOS Xinghe WPS Office. "

　　By other’s faults, wise men correct their own. China securities journal reporter learned from the investigation that the addition of the third-party platform will get twice the result with half the effort for the growth of the native application ecology in HarmonyOS. In November, 2023, mPaaS, a mobile development platform of Ant Digital Branch, signed a cooperation contract with Huawei in HarmonyOS. MPaaS serves hundreds of large and medium-sized customers and thousands of small and medium-sized customers in China, including financial customers such as large state-owned banks, joint-stock banks and Toucheng Rural Commercial Bank.

　　Qi Xiaolong, general manager of mobile technology products of Ant Digital, said: "The mPaaS platform of Ant Digital has more than 2,000 partners. Based on our platform, Android App and Apple iOS App have been developed. Our cooperation with Huawei will not only help us to provide a more compatible version, improve the development efficiency of old customers, but also accelerate the promotion of native applications in HarmonyOS. "

　　According to Qi Xiaolong, mPaaS, an ant math department, participated in some code and architecture design in HarmonyOS. On April 16th, it launched the HarmonyOS native application beta capability set, which can ensure customers to give full play to the performance of HarmonyOS and reduce the difficulty of accessing HarmonyOS Xinghe Edition. At present, about 30 institutions have entered the testing stage.

　　According to the reporter’s understanding, Alibaba Cloud audio and video terminal SDK (software package), Gaode map SDK, Weibo login sharing SDK and other third-party SDKs have adapted to HarmonyOS Galaxy Edition, which will further reduce the development workload of partners and drive more partners to accelerate the development process of native applications in HarmonyOS.

　　According to Huawei, at present, HarmonyOS’s native application ecology has achieved perfect vertical industry coverage, including convenient life, travel, financial management, social information, productivity tools, government and people’s livelihood, news media, audio-visual entertainment, games and other fields, and head applications are scrambling to accelerate the development of native applications in HarmonyOS, continuously injecting new blood into HarmonyOS’s native application ecology.

　　According to industry insiders, the favorite thing about the operating system is that everyone comes to use it. The more users, the better, and the more applications, the better, which is convenient for the operating system to continuously find problems and iterate; What I fear most is that the market ignores it, and the result of indifference is death, which is the home of most operating systems. HarmonyOS system has attracted the attention of many manufacturers, who are willing to invest real money to develop native applications, which is the greatest support and affirmation for HarmonyOS.

　　"Internet of Everything" is the biggest advantage

　　Huawei released Harmony OS (HarmonyOS system) in 2019, which was first applied to Huawei’s smart screen, and began to be applied to Huawei’s mobile phone field in 2021. Counterpoint data show that in the first quarter of 2022, HarmonyOS’s share in the domestic mobile phone market was only 3%, and it increased to 8% in the fourth quarter of 2022 and 16% in the fourth quarter of 2023, showing a steady upward trend. HarmonyOS’s share in the global market reached 4% in the fourth quarter of 2023, making it the third largest mobile operating system in the world after Android and Apple’s iOS.

　　In September 2023, Huawei announced the full launch of HarmonyOS native applications; In January 2024, Huawei said that HarmonyOS Xinghe Edition will be released in the fourth quarter of 2024. The insiders believe that mobile phones are the most important terminal products of Huawei. With the return of Huawei mobile phones to the market, the confidence of consumers and developers in Huawei has been restored. It is timely for Huawei to launch HarmonyOS native applications. Although HarmonyOS’s native application has just started, its three advantages have great appeal to developers.

　　First, Huawei has a large number of terminal equipment. At present, with the return of Huawei’s mobile phone king, products such as tablet, PC, smart screen and smart car are continuously introduced, which will increase the installed capacity of HarmonyOS system. A native Application developer in HarmonyOS bluntly said that Huawei has a huge number of end users, which is the key reason to attract various manufacturers to develop HarmonyOS Xinghe version of the app. "Alipay sees a large number of users of Huawei mobile phones, and definitely hopes that users can use Alipay App on Huawei mobile phones." An insider said frankly.

　　The data shows that there are more than 800 million ecological devices in HarmonyOS, including more than 300 million owned by Huawei. Wang Zhiyu said: "Huawei is an important user channel for Meituan, which is an important consideration for Meituan to join HarmonyOS’s native application ecology."

　　Secondly, technically, HarmonyOS has the advantages of seamless collaborative experience across terminals and multi-terminal deployment at one time. Liu Shuangfeng, chief analyst of CITIC Jiantou Securities and Electronics Industry, believes that Google’s Android system is dominant with its open source characteristics and rich application ecology. Apple’s iOS system has won the favor of a large number of users with its closed ecosystem and excellent user experience. Huawei’s HarmonyOS system takes a different approach, focusing on distributed capabilities. According to the reporter’s understanding, HarmonyOS not only allows users to switch freely between mobile phones, tablets, computers and other devices through distributed technology, but also realizes resource sharing among multiple devices, making it more convenient for users to use.

　　In addition, Zhu Yonggang, president of Huawei Terminal Cloud, said: "The important characteristics of HarmonyOS’s one-time development of multi-terminal deployment enable applications to realize continuous access to services in the fields of tablets, PCs, smart screens, televisions, watches, smart cars, etc., and at the same time reduce the cost of developers. With only one development, new opportunities for commercial returns can be generated on various devices."

　　Many native application developers in HarmonyOS bluntly told china securities journal that although they encountered some technical problems during the development of HarmonyOS Xinghe App, they were able to communicate directly and smoothly with Huawei team, which reduced the communication cost. "We put forward some demands to Huawei, and the Huawei team can respond quickly, which is unmatched by Android and Apple iOS." A developer said.

　　Third, HarmonyOS has huge industrial space. Huawei put forward the strategy of "1+8+N" (1 stands for mobile phone, 8 stands for tablet computer, PC, VR device, wearable device, smart screen, smart audio, smart speaker, car, and N stands for pan-IoT device). HarmonyOS is not just a mobile phone operating system, but an operating system for the Internet of Everything era. According to Haitong Securities Research Report, compared with Android and Apple iOS, HarmonyOS has a large market share in a variety of terminal products, and has a huge market space in the future.

　　Liu Kai, an analyst at Everbright Securities, believes that after half a century’s development, the application software and hardware devices have undergone earth-shaking changes, and the development of the operating system has gone through two complete eras. The first era is the computer era dominated by Windows and Mac OS, and the second era is the smartphone era marked by Android and Apple iOS. With the continuous evolution of technology and the constant change of equipment form, the number of devices connected by the Internet of Things has exceeded 10 billion units, and it has quietly become the most important part of networked equipment terminals, and the era of the Internet of Things has arrived. HarmonyOS, which is oriented to the next generation operating system, is expected to become the leader of the Internet of Things operating system.

　　On January 18th, at the sailing ceremony of HarmonyOS Eco-Qian Fan, Yu Chengdong, managing director of Huawei, CEO of terminal business and chairman of BU, a smart car solution, said that HarmonyOS would open a new blue ocean with a trillion yuan industry. Qi Xiaolong told china securities journal that unlike other OSs, HarmonyOS has a large number of IoT terminal devices, and HarmonyOS has huge industrial space, which is the reason for attracting the mPaaS platform of ant science to join the native application ecology of HarmonyOS. "As a third-party development platform for multi-terminals, we look forward to building an ecosystem with partners such as Huawei and Runhe Software to achieve mutual benefit and win-win."

　　The horizon dawned.

　　It has always been the wish of China people to have their own operating system. But it is not easy to realize this long-cherished wish. This depends on people’s efforts, but also on the progress of the times. Every generation of operating systems can win, which is to seize the cusp of the times. In the Internet of Things era, there should be a new operating system.

　　TechInsights, a research institute, predicts that Android and Apple’s iOS will continue to play a dominant role in the world, and from 2024, HarmonyOS will become the second largest smartphone operating system in China.

　　"Building HarmonyOS’s native application ecology is the most critical thing for Huawei in 2024." On April 17th, Xu Zhijun said that in the past, HarmonyOS’s operating system mostly adapted to various terminal devices in the south, but it still shared the application ecology of Android in the north. Huawei hopes that in 2024, 5,000 applications commonly used on smart phones (the usage time accounts for 99% of the total user usage time) will be fully migrated to the native operating system in HarmonyOS, and the operating system and application ecology will be truly unified.

　　For HarmonyOS system, the dawn of the horizon appears at first sight. In April 2021, Yang Haisong, then vice president of Huawei’s consumer business AI and full-scenario business department, said in an interview that for an ecology, especially for the underlying platform such as operating system, software usage and market share are the core factors for its survival and success, and 16% market share is a life-and-death line. Yang Lin, an analyst at Haitong Securities, believes that there are more than 800 million ecological devices in HarmonyOS at present. From this calculation, HarmonyOS’s global market share has reached 13.11%, which is very close to the life-and-death line of 16%.

　　The reporter learned from the investigation that Huawei’s technical support for developers is indispensable because HarmonyOS is a brand-new operating system. On March 15th, Zhu Yonggang said that Huawei will assist enterprises and institutions to develop more than 5,000 native applications in HarmonyOS by the end of 2024, and finally realize the development of more than 500,000 native applications in HarmonyOS. On April 7, Huawei said that from January 18 this year, Huawei announced that the first batch of more than 200 application vendors were accelerating the development of native applications in HarmonyOS, and by the end of March, more than 4,000 applications had joined the native application ecology in HarmonyOS, with a growth rate of about 20 times in just two months.

　　Zhu Yong just said bluntly that it is impossible to build a native application ecology in HarmonyOS only by relying on the strength of Huawei. The HarmonyOS adaptation of mPaaS, a branch of ant mathematics, means that it will effectively accelerate the "HarmonyOS" of thousands of apps from point to area, and become one of the boosters for the development and growth of native applications in HarmonyOS.

　　Although HarmonyOS’s native applied ecology is developing like a bamboo, it has to face some challenges.

　　First of all, after the technological breakthrough, there is a big gap in the number of ecological applications in HarmonyOS, and it still needs to catch up. As early as May 2019, when Ren Zhengfei talked about the operating system in an interview with the media, he said frankly: "The operating system is not difficult technically, but the difficulty is ecology."

　　According to public information, in the global market, Apple launched the Apple App Store in 2008, and currently there are nearly 2 million apps in the App Store; The Android ecosystem has 2.8 million apps. In contrast, HarmonyOS’s native application ecology has just started, and there is a huge gap. It is urgent to accelerate the development of native applications in HarmonyOS.

　　Secondly, some manufacturers are on the sidelines. An engineer from a big Internet company told china securities journal that many manufacturers are watching Huawei. For example, some big companies are just adding some applications to the native application ecology in HarmonyOS. Xu Zhijun called on all application developers and application owners in China to join HarmonyOS’s native application ecology as soon as possible. In this way, when HarmonyOS Xinghe Edition is really used, it can bring good experience to consumers.

　　At present, Tencent’s WeChat has not announced its participation in HarmonyOS’s native application ecology. By the end of 2023, the combined monthly active users of WeChat and WeChat were 1.343 billion. A native application developer in HarmonyOS bluntly told the china securities journal reporter: "WeChat has a large number of users. In fact, everyone is most concerned about when it will join the native application ecology in HarmonyOS."

　　It is reported that Huawei and Tencent are talking about the collapse, but according to a person familiar with the matter, it is false news that the two sides are talking about the collapse.

　　Many native application developers in HarmonyOS admitted to china securities journal that the native application ecology in HarmonyOS is developing with each passing day. The sooner you join the native application ecology in HarmonyOS, the higher the attention you may get and the greater the traffic. However, for applications such as WeChat, we can’t generalize, and both parties may involve commercial interests and other factors. HarmonyOS’s native application ecology should be enlarged, and developers should also share the industrial cake.

　　In order to promote the native application ecology in HarmonyOS, Huawei has launched the "Yaoxing Plan" of 7 billion yuan, which continuously encourages ecological innovations such as native applications, meta-services and SDK in HarmonyOS. Xu Zhijun said: "When we migrated these 5,000 applications and thousands of other applications to the HarmonyOS operating system, the HarmonyOS operating system was completed and truly became the third largest mobile operating system in the world besides Apple iOS and Google Android."

On January 8, 2023, the 20th Guangzhou International Automobile Exhibition (hereinafter referred to as "Guangzhou Automobile Exhibition") held in New Year’s Eve came to a successful conclusion. At the same time, the official said that the 21st Guangzhou International Automobile Exhibition will open from November 17th to 26th, 2023.

According to the official, this year’s Guangzhou Auto Show opened the newly-built D-Zone Pavilion of the Canton Fair for the first time, with an exhibition scale of 220,000 square meters, attracting a total of 383,000 visitors.

On the first day of media day, we welcomed the launch, listing and pre-sale of more than 60 heavy new cars. In this summary article, you will see: Great Wall Shanhai Gun, Wei Brand Blue Mountain, Chang An Yi Da, Hongqi H6, brand new Crown SportCross, brand new Crown Sedan, brand new BMW M2, brand new Civic TYPE R and brand new Mazda CX-50, etc. The 20th Guangzhou Auto Show can be said to be a successful conclusion for the automobile circle in 2022.

Let’s take a look at its appearance first. In terms of appearance, the Jietu family style is adopted. The air intake grille on the front face is very sharp, and the headlights on both sides are quite sharp. After the headlights are lit, they look very energetic. In terms of waistline design, the new car adopts the waistline design, which prolongs the visual effect of the car to a certain extent. The rim shape is noble and the visual effect is acceptable. In the part of tail modeling, Jetway X70 adopts many popular design elements, and the transverse taillights also have a certain sense of advanced.

In terms of red and black interiors, the new car adopts the latest design style and layout of Jietu, which is very full of technology on the whole. The new car is also equipped with the latest model of Jetway. Above the central control, plastic and leather materials are used, which greatly enhances the grade sense of the whole vehicle. The 10.1-inch central control large screen is simple in screen design, but fully functional. The front row is also equipped with a manual air conditioning control system, which can freely debug the most comfortable space atmosphere. At the same time, the new car also provides leather seats, which can bring certain comfort.

The Jetway X70 has a length of 4749mm, a body width of 1900mm and a wheelbase of 2745mm, which is quite satisfactory. In the same class, the wheelbase of Jetway X70 ranks 36th. As an SUV, its body size does not occupy much advantage in its class, and its internal seating space is only basically enough. After all, it is limited by the length and shape of the body. The 7-seat skylight of Jetway X701.5T dual-clutch jump-enjoy version provides a wider view, which can create a better visual environment and good sensitivity for the rear passengers and increase the light entrance for the whole vehicle. Among the models of the same price and class, Jetway X70 ranks 75th in trunk volume. The shape is very regular, and the storage volume is absolutely no problem for daily use.

In addition to the above description, we can also go to the Easy Car Forum to browse more real car feedback from actual buyers, or use our experience.

　　[car home Technology] After driving for a certain mileage, vehicles often have slightly different driving feelings from new cars, and the reason for this is ultimately attributed to the components that make up the vehicle. Therefore, we have done such a thing, completely disassembling a family car that has traveled 100,000 kilometers in a short time, which is the first time for us.

　　Because it is the first time to make such a topic, we found many problems in the planning process, which may lead to the failure of the dismantling project, such as the dismantling site, vehicles used for dismantling and related technical support. Therefore, we finally decided to cooperate with automobile manufacturers. After a long period of communication, Dongfeng Nissan Qichen accepted our proposal.

● Why choose a car that travels 100,000 kilometers for disassembly?

　　The reason why the mileage of 100,000 kilometers is selected is because when a car travels more than 100,000 kilometers, some faults and problems will gradually emerge, which has little to do with the brand and price of the vehicle, that is to say, even millions of high-end brand vehicles may have various problems.

　　By disassembling a vehicle traveling 100,000 kilometers (disassembling it to the most basic component level, such as a bolt or a bearing), we can tell you which components will wear, especially the chassis system and powertrain system, which are normal and which are abnormal, and how these wear will be related to the final vehicle performance. In this process, we will also tell you how to reduce this unnecessary wear in daily use.

●　Which car to dismantle?

　　Initially, we had several basic requirements for vehicle selection:

　　1. The longer the mileage is on the basis of 100,000 kilometers, the better;
　　2. The vehicle has not been modified in power and performance, and it is all set by the original factory;
　　3. The vehicle has not had any accidents;
　　4. The vehicle is the original paint;
　　5. The vehicle is normally maintained in the 4S shop according to the regulations.

　　The vehicle has not been modified and has not had an accident. At the same time, these conditions are maintained normally, and some interference factors are eliminated as much as possible. Only in this way can the contents presented by disassembly be more representative. Based on the above points, (click for details) we have collected vehicles in the forum. In addition, you may also see the collection information of vehicles in the 4S shop. After screening, a Qichen D50 was finally locked.

● Ran 100 thousand kilometers a year!

　　The Qichen D50 we chose has a mileage of more than 100,000 kilometers in more than one year, and the average daily mileage is more than 300 kilometers. We only know the reason by asking the owner. Because of business needs, car owners often drive back and forth between cities in the Pearl River Delta region. Most of the roads they drive are high-speed and relatively smooth national roads, while the rest are relatively congested and complicated urban roads.

● Where shall we open it?

　　Such disassembly requires the cooperation of the site and relevant personnel. At the same time, we also hope to send the vehicle to a professional institution for testing and verify the state of the vehicle through the test data. Based on the above demand, we transported the vehicle to Dongfeng Nissan Factory in Xiangyang City, Hubei Province for disassembly. It is worth mentioning that it can also be borrowed from the professional test site in the factory to evaluate the vehicle subjectively.

●　Basic information of the vehicle

　　This Qichen D50 was produced in April 2012, and the specific model is the 2012 1.6L manual comfort version. The owner bought this car in June last year. After buying a car, the owner first installed an electric rearview mirror in the 4S shop (it is indeed a very practical configuration, and the manufacturer seems to realize this, which became the standard of the whole department on the 2013 Qichen D50), an anti-theft device, a leather seat and a reversing radar. We found a slight crack at the adjusting button of the electric rearview mirror, which may be caused by the later installation.

　　For more than a year, the owner carried out routine maintenance in the 4S shop according to the provisions of the maintenance manual. At the same time, during the use process, the owner himself felt that there was abnormal noise at the position of the generator and the front shock absorber. After going to the 4S shop for inspection and maintenance, he finally replaced the generator and the right front shock absorber free of charge through the claim procedure. In addition, before lifting the new car, the engine harness was damaged due to the storage problem of the car, so the engine harness was also replaced.

● Owner’s evaluation of the car　

　　In more than a year’s use, the owner is satisfied with the overall performance of the car, and there has never been any breakdown on the way to and from the city. Because it is located in the high humidity and high heat environment in the south, the owner turns on the air conditioner every time he gets on the bus. According to the road conditions explained earlier, the fuel consumption is more than 6 liters per 100 kilometers, and the owner is quite satisfied with this fuel consumption. The owner also thinks that the noise of the engine of the car is relatively small and the gear is very clear. In addition, the owner is also very satisfied with the space performance of the car and the cooling effect of the air conditioner. As for the shortage, the owner thinks that the interior of Qichen D50 is too simple, and I think this is also a compromise that has to be made from the perspective of cost control.

● Editor’s subjective driving experience (static+dynamic evaluation)

　　The vehicle has been explained clearly, and after listening to the owner’s feelings about the car, let’s make a subjective evaluation. Let’s see what changes will happen to the vehicle driving 100,000 kilometers from the most intuitive feeling. To this end,We found a 2013 1.6L manual deluxe version of Qichen D50 (hereinafter referred to as the new car) with a mileage of only over 2,000 kilometers for comparison, thusFeel the difference and difference more obviously.

-Good appearance and interior color.

　　　Perhaps it is because of the relatively short service life and the care of the owner. In short, it is difficult for us to associate this car with driving 100,000 kilometers through static observation. Its appearance and interior color are good, and all functions of the vehicle are normal.

-Abnormal sound may come from generator pulley bearing.

　　After landing, under the condition of quiet external environment, there was abnormal noise coming from the pulley side of the engine crankshaft, and it was preliminarily judged that it came from the pulley bearing of the generator. If this is the case, it can be seen that the generator assembly replaced by claim has the same problem again. But whether the abnormal sound comes from here or not, we have to wait until the disassembly to find the real answer.

　-There is slight abnormal sound at the stop bar.

　　We found that this old car will have a slight abnormal noise when it is in gear, but it will not affect the clarity of gear and the feel of shifting. We feel that this abnormal noise is probably caused by the lack of adequate lubrication of the gear selection mechanism. In the later disassembly, we will further confirm the cause of the problem.

-The noise of the old car is slightly louder than that of the new one.

　　In terms of noise, we selected two points: idle speed and 80km/h (the engine speed is about 2000rpm after the manual gear D50 is engaged in the fifth gear at this speed) to compare and test the new car and the old car. From the results, the new car is better than the old car with a mileage of 100 thousand kilometers, but the advantage is relatively small, especially when idling, the abnormal noise from the pulley of the old car leads to the obvious noise of the old car in idling. In fact, the increase of noise is an unavoidable problem for any vehicle, because the rubber and related materials that play a role in sealing and sound insulation will age to a certain extent with the passage of time, which will lead to the noise can enter, thus making the noise of vehicles rise slightly.

-The dynamic performance of the old car is better than that of the new car before the running-in period.

　　In addition, we entrust a third-party testing organization to test the dynamic performance of two Qichen (one new and one old) (the tires are all new tires of the same brand and series). Judging from the final results, the dynamic performance of the old car that has traveled for 100,000 kilometers is better than that of the new car, and it is not unusual to see this situation. After all, the new car is still in the running-in period, and the power and chassis system have not yet reached the best running-in state. In addition, although the old car has been fully run-in, there will be a certain degree of attenuation in the power system, but the attenuation of this car is not obvious because of its good driving condition, which can also be confirmed by the disassembly of the engine and transmission of the old car in our later period.

-the new car is tighter and the old car is slightly loose.

　　In terms of actual driving experience, we choose to carry out it in a closed test site, where there are many different roads that can simulate the bumps, twists, speed bumps, asphalt roads, stone roads and gravel roads that vehicles may encounter when driving on actual roads.

　　By comparing the test drive of two vehicles, the first obvious feeling is that the new car is more compact and complete, while the old car is slightly loose. When passing through cobblestone sections, the interior parts of the two cars will have obvious abnormal noise, while the old car is more prominent. I think this may be related to the deformation of the plastic parts in the car after a certain period of use and the change of assembly clearance.

　　When I was driving at a speed of about 20km/h on a twisted road with ups and downs, I could obviously feel that the potential energy of the spring could not be reduced and absorbed quickly because of the performance attenuation of the shock absorber in the old car, which made the body bounce relatively greatly, while the body bounce of the new car was smaller. Based on this, we have to dismantle the shock absorber destructively in the later stage to see what happened inside the shock absorber, and please pay attention to our subsequent disassembly report.

Summary:

　　Through subjective driving experience, we have a preliminary understanding of the basic situation of the vehicle. In terms of appearance, interior and various functions of the vehicle, the vehicle has maintained a relatively new level. However, after all, I have already traveled 100,000 kilometers, and I immediately felt the obvious difference through driving. We have also recorded some good or bad situations found, and we will find the corresponding answers for everyone in the later disassembly. (Text/car home Feng Jingyi)

Next notice:

　　At the beginning of this topic, this paper mainly explains the daily use of this vehicle which has traveled for 100,000 kilometers. In addition, we will also analyze the subjective evaluation of static and dynamic driving, and find the answer to the question through detailed disassembly in the later period.

　　[car home Technology] With the increase of mileage, the aging characteristics of vehicles are becoming more and more obvious. For drivers, abnormal noise is the most intuitive category. As mentioned in our previous article, the owner judges that there may be some problems in the vehicle based on abnormal noise, and the subsequent inspection results also confirm the reliability of this intuition, and those silent changes are also taking place. We ended them when the odometer of Qichen D50 entered the 100,000-kilometer mark. This article will show you the situation of the body and chassis.

　　If you don’t know what we are doing, it is necessary for you to know the contents of the first stage, such as why we are doing this, how we choose the car, and of course, the general situation of disassembling the car is also very important. (Click for details)

The second stage: body disassembly

　　Don’t underestimate the structure of this energy-absorbing box. Through literal understanding, we know that its function is to absorb collision energy by virtue of its own deformation in the event of collision, so as to reduce the impact on the back.

　　It’s easy to say, but it needs careful design to achieve better energy absorption effect. On the one hand, the wrinkle design on its surface divides the energy absorption process of the energy absorption box into three parts, which makes the energy absorption process of each part relatively independent and stable, and the position and amplitude of these two folds are obviously calculated through a lot of calculations. In addition, the energy-absorbing box connected by bolts can effectively control the maintenance cost.

　　In the energy-absorbing box, different cars have different structures, some cars are not equipped with energy-absorbing boxes, some cars are equipped with energy-absorbing boxes but have no wrinkle design. In addition, there is a difference in the connection mode of energy-absorbing boxes. Some cars’ energy-absorbing boxes are connected with anti-collision beams and longitudinal beams by welding.

☆ Door disassembly

Further disassembly in the car

　　The next step is to disassemble the car body further. In the end, what we see is just a car body, just like the car body we see in the painting workshop every time we visit the factory. Although it is impossible for us to judge the anti-corrosion ability of the car body by using it for more than one year, when it is "naked" in front of us, we can clearly see the structure of the car body and the workmanship inside and outside. This is also a very noteworthy link.

☆ Passenger compartment structure

　　As we all know, the coating process carried out in the vehicle manufacturing process can ensure the corrosion resistance of the car body. As long as the paint surface of the car body is not damaged in the later use of the car, in general, the car body steel plate can be guaranteed not to be rusted in 10 years. Of course, the process of the steel plate itself is also very important. We learned from the manufacturer that the Qichen D50 uses galvanized steel plate with good corrosion resistance, which also ensures the aging resistance of the car body to a certain extent.

☆ Details of the cover

☆ The mystery of pedal

　　As we expected, there are no signs of years such as rust or dim color on the surface of the car body. For such a car with a driving time of about one year, it is really difficult to judge its anti-corrosion performance, but in any case, we can still gain something in the process of disassembling the car body, such as the materials and structure of the car body.

The third stage: chassis disassembly

　　According to our previous experience of comparing the test drive of new and old models, Qichen, which has traveled for 10,000 kilometers, did show some fatigue in the chassis link. For example, after passing through the ditch and ridge road for many times in a row, the vibration absorber’s ability to restrain the body shaking has declined, and we hope to find the answer in the subsequent disassembly.

● Suspension disassembly

● Front suspension disassembly

　　The front suspension structure of Qichen D50 is McPherson-style, and the process of detaching it from the car body together with the subframe is not complicated. The subframe and the car body are connected by four bolts, but before loosening them, we need to disconnect the connection between the damping strut and the car body and the engine support elements, and then the suspension assembly and the engine are detached together. Next, we will analyze the suspension disassembly, and the engine disassembly will be arranged at the end.

☆ steering rod ball

　　Under normal circumstances, the car that has traveled for 100,000 kilometers is prone to problems, which is the abnormal sound or looseness caused by the aging of the rubber parts of the chassis. The ball head of the steering rod is a part that is prone to problems. The ball head of the steering rod is responsible for connecting the steering rod and the steering knuckle. Besides the ball head, there is lubricating oil in it. Once the rubber sleeve outside is damaged due to aging, on the one hand, the lubricating oil will leak out; on the other hand, dust, dirt and rain may also enter the ball head, which will accelerate the wear of the ball head, and then the damping force on the swing of the ball head will become smaller, and its interior will begin to wear and gradually become loose.

　　For the driver, it may be felt that the virtual position of the steering wheel is getting bigger (loose and spacious, which can be felt by shaking the wheels with both hands after lifting the car). On the other hand, it will also affect the stability of the vehicle when it is dynamic to some extent. From the disassembly of Qichen D50, we can see that the steering rod ball head is in good condition, and the steering wheel is not found to be too empty during the previous test drive, so it can be judged that there is no problem in this part. However, the aging of rubber covers is also related to time, which generally does not happen when the car is used for more than one year.

☆ Steering knuckle and bearing

● Rear suspension disassembly

　　The rear suspension of Qichen D50 adopts the longitudinal arm torsion beam structure, and the simple structure is the advantage of this kind of suspension structure, especially for compact cars like Qichen D50, it is particularly important to contribute more space to the interior of the car.

● Brake pad wear

● Disassemble shock absorber

　　The situation that the body sway can not be suppressed as soon as possible is mostly directly related to the shock absorber. With the increase of mileage, its performance will gradually decline. In addition, continuous and high-intensity work will also reduce its performance.

　　Before disassembling, we made a static comparison of the height of the car body. In the case of no load, there was no obvious difference between the heights of the old and new cars, which to some extent showed that there was no big problem with the springs supporting the height of the car body. Next, we will further disassemble the shock absorber strut and shock absorber.

　　This kind of shock absorber with double-tube structure is widely used in ordinary household cars. After many times of intensive work, the hydraulic oil and air inside may be mixed together, which will lead to a large number of bubbles in the hydraulic oil. In this state, the performance of the hydraulic oil is bound to be greatly affected. This may be the reason why the car body shaking in Qichen D50 cannot be suppressed as soon as possible. The above is only our theoretical analysis according to the structure.

● Vibration isolation state between spring and car body

● Abnormal wear of tires

☆ Wear difference between front and rear tires

　　When cleaning up the workshop, we accidentally found that the removed tires showed signs of abnormal wear. Usually, this is related to the four-wheel alignment of the vehicle and daily use.

　　According to our understanding, the tires of this Qichen D50 have not been changed during the driving period of 100,000 kilometers. Only during the maintenance period, the maintenance technician found that the wear of the front and rear tires was obviously different, and the front and rear tires were switched. However, we can still see some clues from the wear of the tire surface.

　　For most (engine-front) vehicles, because the center of gravity of the vehicle is relatively forward, the pressure on the front tire is greater. According to the physical definition, the friction between the tire and the ground is greater when the contact area is fixed. In contrast, the wear of the front tire is more serious than that of the rear tire.

　　From this point of view, it is very necessary for us to switch the front and rear tires regularly during our daily car use, which can make the wear state of the front and rear tires more uniform, thus delaying the service life of the tires. Specifically, the front-back exchange or diagonal exchange can be adopted, but if the tire has a rolling direction mark, then the same side can only be used for the front-back exchange when the tire is transposed. This requires special attention.

☆ Eccentric wear of tires

　　In addition to the difference between the front and rear tires, the tires used as front wheels for a long time have eccentric wear. From the tire surface, the degree of wear on the outer side is more serious.

　　This may be a problem with the four-wheel alignment of the vehicle, but it may also be caused by the tire being in a state of insufficient air pressure for a long time. Modern cars tend to set camber to a negative value to improve the driving stability of the vehicle. If the tire is in a state of insufficient air pressure, it will aggravate the wear on the outside of the tire when the vehicle turns.

Editor’s summary:

　　The Qichen D50, with a mileage of over 100,000 kilometers, shows no obvious signs of aging in the body and chassis. Among them, because the service life of the vehicle is about 1 year, and under normal circumstances, the painting process can ensure that the car body will not be rusted for 10 years, so it is difficult to fully show the anti-corrosion state of the car body. In addition, in the chassis link, we focused on the problem of vehicle body sloshing after passing through the ditch and ridge. Through structural analysis, after many bumps, the mixing of oil and gas in the shock absorber may be the chief culprit leading to damping attenuation. No signs of aging were found in the rubber bushings between the various connectors of the chassis. On the one hand, the quality of the components themselves was excellent, on the other hand, it was related to driving habits and car use time. In the next article, we will disassemble the powertrain. Compared with the body and chassis, the driving of 100,000 kilometers is a greater test for this part. (Photo/Text car home Li Boxu)

　　[car home Technology] In the first two issues, we made a subjective evaluation of a Qichen D50 that has traveled for 100,000 kilometers, and tried to find out the possible changes of the chassis system and the body through disassembly. In this article, we will disassemble the core powertrain in detail to see what changes it will have after 100,000 kilometers of operation.

　　If you don’t know what we are doing, it is necessary for you to understand the contents of the previous stages, such as why we should do this, how we choose the car, and the disassembly of the body and chassis.

The fourth stage: engine disassembly

● Find the source of abnormal noise on one side of the engine pulley.

　　First of all, we have to remove the generator, air conditioning compressor and other accessories from the engine. We turned the pulley of the removed generator by hand, but we didn’t find the abnormal sound we heard in the subjective evaluation before. It can be seen that the abnormal sound didn’t come from this, and finally it was determined that the root cause was the tensioner.

　　Generally, the design concept of Japanese manufacturers is to achieve the initial requirements through the simplest structure as possible, so the design similar to Qichen, which is adjusted by screws, can automatically adjust the tightness of the belt according to the tightness of the belt, although it is not like the automatic tightening wheel designed by German manufacturers, but its advantage lies in its durability.

　　Although the belt connecting the engine accessories is not like the timing belt (most vehicles use timing chain nowadays), once it breaks, the intake and exhaust valves of the engine will be seriously damaged, but it also needs to be checked daily. If it strikes, the generator will not work and the vehicle will break down.

● Cooling circulation system

● clutch

● Wear of crank-connecting rod mechanism and valve timing mechanism

　　Both crank-connecting rod mechanism and valve timing structure run well after 100 thousand kilometers. Although you can clearly see the friction marks, they are all normal phenomena. This is not only due to the manufacturing accuracy, but also due to the engine oil, and changing the engine oil regularly is the best protection for these metal parts that are always in a harsh environment.

●　Variable valve timing system with high requirements for oil cleanliness

● Carbon deposition in injector and piston

● Carbon deposition in intake and exhaust systems

　　Although we often mention the word "carbon deposit", it will still be incredible when we see these things strongly attached to the relevant parts of the engine. Indeed, no matter how good the oil, car habits, car environment and other conditions are, carbon deposition is always inevitable, but some cars are more serious and some cars are less serious. For example, it is easier to form carbon deposition when driving on congested roads in cities, and once it is formed, it is difficult to completely remove it.

Stage 5: Disassembly of manual transmission

　　For friends who don’t know much about the structure of manual transmission, it is strongly recommended to click on the article "Manual transmission you don’t know: the mystery under the shift lever" to learn.

Full text summary:

　　After 100 thousand kilometers, the powertrain system is still in good condition, especially the degree of wear is low, so the importance of regular maintenance is self-evident. However, the generation of carbon deposit is inevitable. When it is serious, it will have a great impact on fuel consumption and power. If you want to completely remove it, you must completely disassemble the engine to solve it.

　　At this point, our topic of "100,000-kilometer vehicle dismantling" is over. Through dismantling, we show you what changes will happen to a vehicle that travels 100,000 kilometers, so as to help you develop good driving habits and strengthen the daily inspection and maintenance of the vehicle. As the saying goes, "three-point repair and seven-point maintenance", only in this way can we better enjoy the life of owning a car. (Text/car home Feng Jingyi)

　　Cctv news(Focus Interview): Speaking of big data, everyone is no stranger. At present, online shopping, mobile payment, smart transportation, epidemic prevention and control are all inseparable from the support of big data, which has been integrated into all aspects of our lives.

The offline audience adopts the reservation system and visits at different peaks.

　　In the artificial intelligence exhibition area of the Expo, all kinds of robots are very attractive. The 5G remote ultrasonic robot can complete the whole process of remote ultrasonic diagnosis, and the new infrastructure, smart future and new experience based on 5G network have also become the focus of attention. The technology company exhibited a helmet monitoring system based on 5G network, artificial intelligence and big data technology. As long as you enter the designated area, the system will automatically identify whether you are wearing a safety helmet and give an early warning.

　　New products and applications of big data have also become more accessible in life. In the Smart Industry Pavilion, the smart system of an enterprise can collect the physical signs data of human body during sleep for a long time, process and analyze the data, and give personal health guidance programs. At present, this enterprise has cooperated with some old-age care institutions to explore a new model of smart old-age care.

　　With the empowerment of big data, cities become smarter. In this year’s Digital Application Pavilion of Digital Expo, this exhibitor from Shanghai brought new applications of big data. On this system, big data technology focuses on the key areas of Shanghai’s urban management and operation. The establishment of intelligent model can comprehensively monitor the overall state of urban water supply system, and send out warnings and reminders in time when problems are found.

　　In addition to the water system, the brain of the city has begun to predict in advance the fields of transportation, fire safety and smart parking.

　　Guizhou, the host of the Expo, is an important pioneer area for China to implement the big data strategy. Since the establishment of the National Big Data Comprehensive Experimental Zone in Guizhou in 2016, new achievements have emerged in the development and application of big data in the fields of economy, society and people’s livelihood. At this year’s Expo, the digital government work platform was displayed in the exhibition hall of Guizhou on the Cloud, which broke the data barrier and brought new changes to people’s lives through data exchange and sharing among different departments. At present, in the mobile terminal run by Guizhou Netcom, the government service functions of different departments are classified together.

　　The technical application of the smooth flow of data not only makes people run less wrong roads, but also shows their talents in consolidating the achievements of poverty alleviation. Heiyan Village, jiangkou county, Tongren City, used to be a second-class poverty-stricken village, but now it has been lifted out of poverty. Some time ago, Guizhou Poverty Alleviation Cloud Big Data System sent monitoring and early warning information to Heiyan Village: More than half a month ago, a villager named Long had heart surgery in the Municipal People’s Hospital, and the village cadres needed to verify the situation as soon as possible. In the morning, the poverty alleviation cadres came to the villager’s home.

　　After confirming that the medical expenses and other related expenses did not pose a risk of returning to poverty for this family, Hu Yinxi logged the verification results into Guizhou Poverty Alleviation Cloud System.

　　Such a big data monitoring system has strict authority settings and shields personal sensitive information, mainly monitoring the data of unexpected situations that have the risk of returning to poverty in production and life. At present, Guizhou Province has included groups such as unstable poverty-stricken households and marginal households in the scope of big data monitoring. If there is a risk of returning to poverty or causing poverty, it will accurately analyze the reasons and eliminate the risks through effective measures.

　　This year is a crucial year for consolidating and expanding the achievements of poverty alleviation and effectively connecting with rural revitalization. After several years of development, big data technology has been applied in rural revitalization. Therefore, this year’s Digital Expo has also set up a section called "Big Data Helps Rural Revitalization". From the aspects of big data and rural environmental governance, rural e-commerce, tourism and agricultural industry integration, we will demonstrate and explore big data to empower rural revitalization.

　　The key to rural revitalization is to do a good job in industry. The "pepper cloud" on display at a booth caught the attention of reporters. On the "Pepper Cloud" platform, the data of the whole industrial chain, such as planting process, agricultural science and technology, meteorology, soil, humidity, landform and detection, are integrated, and big data technology is used to promote standardization for scattered farmers.

　　The "Pepper Cloud" platform, which breaks the problem of data collection and promotes standardized planting, relies on smart phones and big data model algorithms to insert wisdom wings for small peppers in mountainous areas. In Taiping Village, Zheng ‘an County, Guizhou Province, the 500-acre pepper planted by villager Wan Hong grew well, but weeds grew in the field and the pepper branches grew to the length of pruning. Wanhong, who was at home at this time, received a reminder from the agronomist on the platform on her mobile phone.

　　In a short time, in addition to a large area of weeding in wanhong’s pepper field, he quickly took out his mobile phone and took a few photos of the on-site completion and uploaded them to the "cloud platform" of the mobile phone.

　　On the "Chili Cloud" platform, whether the work is qualified or not is calculated by the data brain.

　　In addition to showing the latest applications of various innovative technologies based on big data in economic and social fields, the number fair has also become a new platform for the competition and development of innovative technologies. At this Expo, the announcement of the results of the selection of leading scientific and technological achievements awards attracted much attention. Among the 49 award-winning projects finally selected, seven projects including the research and application of bus-level data center network technology won the Black Science and Technology Award.

　　"The number of wisdom changes, and things are new." After seven years of development, the Expo has not only become a platform for the display and exchange of innovative technologies, but also built a bridge for the integration of China’s big data industry with the world and become an important platform for attracting foreign investment.

　　Big data has been widely used in China’s economic and social development, and the pattern of rapid development of big data industry has basically taken shape, but it still faces many challenges in data open sharing, core technology breakthrough and big data-driven development. The Expo provides a platform for innovation, integration and communication to meet these challenges. For the development of big data that has become a national strategy, activating, mining and applying big data and exploring more new technologies, new formats and new models can generate greater value and empower high-quality development.

　　Overseas Network September 10th US media reported that Ireland’s data regulator has issued a preliminary order to Facebook, asking the other party to stop transmitting relevant data of EU users to the United States.

　　According to a report quoted by the US Consumer News and Business Channel (CNBC) on the 10th, the preliminary order was issued to Facebook by the Irish Data Protection Committee (DPC) in August. Nick Clegg, Facebook’s vice president of global affairs and communications, pointed out in a blog post published on Wednesday (9th) that DPC has started to investigate Facebook’s data transmission in the European Union and the United States.

　　The report was released a few months after the European Court of Justice ruled that the data transmission standards between the EU and the United States could not fully protect the privacy of European citizens. The European Court of Justice (ECJ) is the highest legal institution in the European Union. After determining that EU citizens have no effective way to counter the monitoring of the US government, the court restricted American companies from sending European user data to the United States. Theoretically, American institutions such as the National Security Agency (NSA) can ask Internet companies such as Facebook and Google to hand over data about EU citizens, while EU citizens are kept in the dark.

　　The European Court’s ruling came after Schrems, an Austrian privacy activist, filed a lawsuit based on a disclosure by Edward Snowden, who claimed that American law did not provide sufficient protection against surveillance by public authorities. Schrems filed a complaint against Facebook, which, like many other companies, is transmitting data of Schrems and other users to the US government.

　　The court ruling invalidated the EU-US privacy protection agreement, which had enabled these American Internet companies to transmit data of EU citizens across the Atlantic. After the verdict, these American Internet companies began to rely on standard contract terms (SCC) to transmit data.

　　Clegg, former British Deputy Prime Minister, said that the Irish Data Protection Committee had begun to investigate the data transmission in Europe and America controlled by Facebook, and suggested that SCC should not be used for data transmission in Europe and America in practice. If SCC cannot be used as the legal basis for data transmission, Facebook will have to cancel most of the data collected by European users. DPC may impose a fine of 4% of Facebook’s maximum annual income, or if it fails to comply with the ban, it will be fined 2.8 billion US dollars (about 19.14 billion yuan).

　　Although the order applies to Facebook, DPC may issue similar orders to other American technology giants, which may cause serious damage to its business. Clegg went on to point out that the primary task of the EU is to ensure that users, advertisers, customers and partners in Europe can continue to enjoy Facebook services while maintaining the security of their data, and that European countries will continue to transmit data in accordance with the recent ruling of the European Court of Justice until further guidance is received. He also warned that companies need to abide by clear global rules to protect transatlantic data flows for a long time. (Overseas network Hou Xingchuan)

Ford L was released at Shanghai Auto Show in April, 2023. Its body length, width, height and wheelbase are 5000 mm, 1961 mm, 1773 mm and 2950mm, respectively, which makes it have obvious space advantages in medium-sized SUVs. The price range from low-priced fuel version to high-priced hybrid is 229,800 to 309,800 yuan, which can be said to cover the price range of mainstream compact, medium-sized and medium-sized SUVs, regardless of product strength.

However, from listing to the end of 2023, the total sales volume was 25,502 vehicles, with an average monthly sales volume of 2,125 vehicles, ranking 197th among the national passenger car sales. After combining the strength of its products, it is really a pity that such a flat sales performance has been achieved. You know, the average monthly sales volume of the same power split hybrid technology reached 6120 units.

Of course, the performance of sales volume is related to many factors, first of all, the product strength. Ford Sharp L adopts the latest design language of Ford family, and the spoke lattice air intake grille with dynamic LED headlights gives this SUV a strong visual impact, which is extremely aggressive compared with the old one.

The side of the car body is slender, and the uplift design of the C-pillar position adds a sense of movement. In terms of interior design, it is equipped with a 12.3-inch full LCD instrument panel and a 27-inch touch screen, which is reasonable in layout and convenient to operate. It not only provides rich information for passengers, but also enhances the sense of interactive experience. In terms of spatial layout, Ford Sharp L has realized the design of 2+2+3 with a wheelbase of 2950mm, and the maximum legroom in the second row is 1,190 mm. It is equipped with seat ventilation, heating, independent temperature zone control, wireless charging, etc. It can switch the near-zero gravity mode with one button, the backrest angle can be adjusted backward to 41 degrees, and the included angle between the backrest and the seat cushion can reach 105 degrees, making it comfortable to ride. The narrowest distance of the central passage is 200mm, and the armrest can easily enter and exit the third row after being folded, so that family users can experience comfort and convenience whether they travel daily or long distances.

However, the design is a matter of opinion, mainly in the actual experience, most users feedback that the hidden door handle can not be extended after unlocking, and it can be replaced or repaired through warranty. The display effect of the central control screen is average, and there will be problems such as crash, slow response, occasional blue screen, and unable to change the driving mode during use, which can be solved by restarting and upgrading the car. In the process of driving, the driver’s and passenger’s doors will produce abnormal noise when traveling in bumpy road conditions. The main reason is that the lock collides with the door lock, which can be solved by wrapping tape. There are also small problems such as abnormal sound of skylight and stuck ignition switch, which are within the scope of recall. In addition, the Ford Sharp L platform has been downgraded from the previous generation CD4 to the same C2 platform as Ford. Ford and Lincoln also use this platform. The material of the chassis suspension swing arm has been replaced by the seemingly cheap iron, which invisibly reduces the brand power and affects the choice of Ford potential users to a greater or lesser extent.

To sum up, even if Ford Sharp L’s product strength is excellent, there is still much room for improvement in terms of quality reliability and brand strength. At the same time, in the impression that American cars bring to consumers, oil consumption seems to be an indelible stain. The Ford Sharp L 2.0T EcoBoost E- hybrid will make you change your view of American cars.

Ford Sharp L 2.0T EcoBoost E- hybrid is equipped with a hybrid system with power split configuration. When it comes to this technology, most people will take the lead in thinking of Toyota’s THS hybrid system. Yes, the hybrid configuration of Ford and Toyota is completely the same. However, Ford did not copy or buy Toyota’s hybrid technology. Strictly speaking, it is more appropriate to call it technology sharing.

Power split configuration was not first put forward by Toyota or Ford, but a design concept put forward by TRW Company in 1960s. When the development of new energy technology was officially valued by the main engine factory, Toyota and Ford began to develop this hybrid configuration at almost the same time. Among them, Toyota has made breakthroughs in control system and energy management, while Ford has put more energy into hybrid configuration and machinery manufacturing. In 2004, Ford signed an authorization agreement with Toyota. The details are that Ford replaced 20 patents related to hybrid technology with diesel engine technology. This behavior was misunderstood by many people. It was considered that Ford’s hybrid technology originated from Toyota, which is actually a kind of patent cross-authorization, because in the configuration of power split hybrid system, neither Toyota nor Ford can avoid each other’s patents. After evading the legal issues, Ford began to make great efforts in the power split hybrid configuration, including control strategies and algorithms, and applied for more than 100 patents.

So today, 20 years later, we saw this latest hybrid system on Ford Sharp L. The 2.0T EcoBoost E- hybrid consists of the fifth generation 2.0T EcoBoost single-turbo twin-turbo supercharged dual-injection engine and the eCVT transmission with dual motors. The maximum power is 202kW/5500rpm and the maximum torque is 405Nm/3000~4000rpm. Compared with Toyota 2.5THS, the power performance is better, and compared with Toyota 2.4T hybrid system, the cost control is better.

In the hybrid system, the engine uses a 350-bar dual-injection fuel system, which can automatically select the intake manifold or in-cylinder direct injection fuel injection mode according to the working conditions, which can better balance the low fuel consumption at uniform speed and the power performance at high power demand. At the same time, it also adopts hydraulic control OCV, VCT, valve mechanism and EGR exhaust gas circulation system. The eCVT transmission, code-named HF55, adopts a set of Power-Split structure in which the engine and generator are coupled by planetary gear sets, and the motor, motor controller, vehicle controller and gearbox are highly integrated. It has the characteristics of compact structure, energy saving, high efficiency, smoothness and sensitivity, and the maximum output torque can reach 5000Nm. Among them, both generator and motor are developed by Ford, and flat wire winding technology is adopted. The slot full rate exceeds 60% and the efficiency reaches 96.2%. With the oil cooling technology of frequency conversion electronic oil pump, the motor speed can reach 17000rpm, the driving motor output power is 140kW, and the torque reaches 320Nm.

The new low-nickel NCM111 ternary lithium water-cooled battery pack comes from BYD. It adopts an integrated high-efficiency water-cooled system, which not only has excellent heat dissipation performance, low risk of thermal diffusion, but also has a long cycle life. It has passed many rigorous tests exceeding national standards such as overcharge, acupuncture, seawater immersion, salt spray, drop, high and low temperature impact and cycle life, and can maintain the normal and safe operation of the battery under extreme conditions. Even at low temperature in winter, the battery pack of the hybrid system can cooperate with the new generation of EcoBoost twin-vortex turbocharged engine to realize continuous and stable automatic charging and discharging.

During the driving process, the whole system can be freely switched between pure electric drive, hybrid drive and electric assist. When various modes are switched, the NVH of the whole vehicle will be very natural. Even when the engine is started or accelerated with a large throttle, the driver and passenger will not feel the sharp attack of noise and vibration after the engine is started, but can only vaguely hear the noise with coarse particles when the engine is running.

The dynamic performance of the whole vehicle takes into account responsiveness and smoothness. However, in the power connection at the moment when the engine is involved, there will be a rush feeling dragged by the power. Although it is small, the ride comfort needs to be improved compared with Toyota’s hybrid system.

It is worth mentioning that the vehicle control system accurately calculates the optimal efficiency of the engine and motor, and automatically matches the optimal driving mode according to the actual working conditions, so that the hybrid power system always runs in the optimal efficiency interval. Considering the total mileage of 800 kilometers in urban areas, highways and suburban mountain roads, the average fuel consumption reaches 8.4L/100km, of which 188.5km is for pure electric driving. For a hybrid SUV, this fuel consumption may not be the most fuel-efficient, but considering its power performance and 5 meters.

Except for the engine, the most obvious difference between Ford’s power splitting technology and Toyota THS is the four-wheel drive system. In Toyota THS, the E-Four four-wheel drive system is adopted, that is, the engine and the driving motor drive the front wheels, and the driving motor located at the rear axle drives the rear wheels. There is no transmission shaft between the front and rear axles, and the power distribution is automatically controlled by the electronic control system. In the Ford Sharp L 2.0T EcoBoost E- hybrid, there is a transmission shaft leading from the output end of the hybrid system to the rear axle, realizing a real four-wheel drive system, which not only can bear higher load and bring better four-wheel drive performance, but also takes into account fuel economy.

Topic: Israeli bombing of Gaza Strip.

　　Experts say "the seventh Middle East War" is unlikely to break out.

　　Shang Bin, a special correspondent of Global Times, reported that in recent days, the situation in the Middle East has suddenly become tense with the intensive Israeli air strikes on the Gaza Strip. On the 29th, Israeli Defense Minister Barak said that his country was waging an "all-out war" against Palestinian militant group Hamas and its leaders.

　　On the 30th, an Israeli spokeswoman declared to the outside world that her country was ready to launch a ground offensive against Gaza. In the face of Israel’s fierce offensive, Hamas also declared that it would launch a "third uprising" to defeat the Israeli regime. Will the Middle East, which has been baptized by war, fall into a tragic war again? Will the development of the situation lead to the outbreak of the "Seventh Middle East War"? In this regard, the Global Times reporter interviewed several scholars on Middle East issues, and they all agreed that there is little possibility of another Middle East war.

　　Gao Zugui, an associate researcher at China Institute of Contemporary International Relations, said that this time, Israel launched an "all-out war" against the Palestinian militant group Hamas, not against the whole of Palestine. More importantly, Abbas, president of the Palestinian National Authority, who can represent Palestine internationally, has "exercised restraint" and does not want the conflict to escalate. Moreover, Israel and neighboring countries of Palestine are unlikely to get involved in this conflict, which makes it unlikely to develop into a full-scale Middle East war. He said that Egypt and Israel have signed a peace agreement, Syria has also held indirect negotiations with Israel and reached some consensus, while other countries such as Jordan are unlikely to get involved.

　　Wang Jinglie, director of the Middle East Research Office of the China Academy of Social Sciences, said that the Israeli attack on the Gaza can be called a "shocking" violence in the 21st century, but there is little possibility of another Middle East war in the region. He said that all the wars in the Middle East in history have involved neighboring countries, but the current conflict is only between a country and a radical organization in Israel, and it is not a big war in scale. In addition, from a deeper perspective, this war has been "planned for a long time" by Israel, and its purpose is very clear, that is, to eradicate Hamas, not the whole Palestinian territory. In addition, whether it will develop into another Middle East war depends on the attitude of neighboring countries. If neighboring countries are also involved in this conflict, it may lead to the expansion of the situation and the outbreak of the Middle East war. However, moderate countries such as Egypt, Saudi Arabia and Jordan are unlikely to be involved in the conflict, and Syria and Lebanon are unlikely to be involved. Although Iran is a variable, it is unlikely to be involved. Therefore, at present, it is unlikely that another Middle East war will break out.

　　Another international scholar also believes that the possibility of another Middle East war is very small. Strictly speaking, he said, the conflict between Israel and Hamas is not a "war" because it is not between two countries. In addition, the purpose of Israel’s attack is to "pull out" the nail of Hamas, which also limits the scale of the conflict.
