"It’s so obedient that it will automatically open the door as soon as it hears me coming to it. When I wash the car, I have to put my mobile phone far away." On April 18th, at the Shanghai Auto Show, Tang Wei, the owner of Zhiji, shared that the car is smart, but I hope it won’t automatically open the door when washing the car. Tamia Liu, co-CEO of Zhiji Automobile, responded at the scene and iterated at the fastest speed.

Intelligentization brings a lot of convenience to the car. Taking the mobile phone as an example, it can replace the function of the car key, start the air conditioner remotely, unlock it, authorize friends to drive the car, etc. When the owner approaches the car with his mobile phone, there are interactions such as flashing lights, honking horns and opening the car door.

However, just like what happened in Tang Wei, while intelligence brings convenience, it will bring some new troubles due to thoughtlessness. The interaction between Tang Wei as the owner of Zhiji and the brand has also become a vivid scene of automobile intelligence ecology. Automobile intelligent manufacturers have designed many scenes to meet the wishes that can only be imagined but cannot be realized in the traditional automobile era. In the process of using, the owner found unreasonable points, and the comprehensive data was continuously fed and learned. After investigation, design, feedback and promotion, the upgrade iteration was quickly completed.

The intelligent problem raised by Tang Wei is the focus of the release of Zhiji at the Shanghai Auto Show. The AI4M intelligent strategy announced by Zhiji takes "AI" artificial intelligence as the core, so that cars can observe, think and act like "people", and the goal is to let everyone have a dedicated driver.

In order to achieve this goal, Zhiji said that it will rely on the scientific and technological accumulation of SAIC for many years and the core self-research of Zhiji Automobile since its establishment three years ago, and at the same time deepen the strategic cooperation with Alibaba Cloud, Zebra Zhixing, Momenta and other leading forces in the field of intelligent technology in China, actively lay out the whole chain closed-loop innovation of the brand-new intelligent electrical architecture, and launch the "China Intelligent Scheme".

Zhiji believes that the AI era has accelerated the landing speed of artificial intelligence in the real world. In the field of autonomous driving, perceptual intelligence and cognitive intelligence are two key issues that need to be solved urgently. In the past few years, perceptual intelligence has received full attention from the whole industry. While improving perceptual intelligence, Zhiji cooperated with Momenta, a global head intelligent driving algorithm player, to launch the industry’s first D.L.P artificial intelligence decision planning model.

Zhiji took the lead in using deep learning to plan, greatly improving the takeover rate and realizing the driving ability like an old human driver. According to the on-site introduction of Tamia Liu, the current takeover rate is about once per 100 kilometers, and it will increase tenfold every two years. In the future, the takeover mileage will increase to once per 1000 kilometers or even once per 10,000 kilometers.

Based on this strategy, the high-speed elevated NOA (Automatic Aided Navigation System) will be launched on Zhiji L7 at the end of April. The first batch of open cities will be "Shanghai, Jiangsu, Hangzhou, Jiaxing and Lake", and LS7 will be upgraded and promoted to the whole country within this year.

By then, NOA of Zhiji can carry out dynamic path planning for closed high-speed elevated roads, and complete lane keeping, automatic speed adjustment, active lane change overtaking, automatic up-and-down ramp and other behaviors within the design area.

Tamia Liu emphasized that after completing the game calculation of active lane change and gap insertion, the driving quality is actually a highlight of Zhiji. Zhiji NOA’s driving behavior deeply learns from professional drivers, not frequently accelerating and decelerating, but making reasonable and comfortable actions to complete the instructions.

Zhiji said that the intelligent strategy with AI as the core is not just a written plan. In the second half of 2023, an intelligent medium-sized city cross-border SUV will be launched to solve the pain points of users in urban travel with intelligent solutions. An intelligent sports coupe, which is expected to be launched in 2024, is equipped with the latest Qualcomm 8295 high computing power chip, takes the lead in adopting solid-state batteries and adopts a brand-new three-electric system including carbon fiber rotor technology. The car will enter the "2-second acceleration club" and fully reproduce the F1 driving experience. The two models launched in 2025 are based on a new vector magic architecture and a modular magnetic open platform, which reconstructs the vehicle space and allows users to enjoy a subversive intelligent experience.

How to break the industry difficulties when the signal of centralized collection of Chinese patent medicines comes out?

On August 9, 2021, the National Medical Insurance Bureau issued the Reply of the National Medical Insurance Bureau to Recommendation No.4126 of the Fourth Session of the 13th National People’s Congress, stating that "on the basis of improving the quality evaluation standards of Chinese patent medicines and formula granules, we will adhere to quality priority, take clinical demand as the guide, and start with high-priced and large-quantity varieties to scientifically and steadily promote the centralized procurement reform of Chinese patent medicines and formula granules".

The introduction of this reply means that the procurement of Chinese patent medicines and even granules has been put on the agenda. However, as the first batch of people in China who participated in centralized drug bidding and purchasing and engaged in big data research of traditional Chinese medicine for a long time, the author is not optimistic about the procurement of traditional Chinese medicine in the short term.

Say so, we might as well stroke the train of thought:

01

What is the quantity purchase of traditional Chinese medicine?

"Drug procurement with quantity" refers to defining the procurement quantity when bidding or negotiation is carried out in the process of centralized drug procurement, so that enterprises can quote according to the specific quantity. This procurement method is also the goal that China has been striving to achieve for many years. In fact, this method is also an upgraded version of the centralized bidding and purchasing of drugs in medical institutions nationwide since 2000, which is no stranger to the vast number of pharmaceutical and medical device manufacturers at home and abroad. However, it is really a new thing for domestic Chinese medicine production enterprises, especially Chinese medicine decoction pieces enterprises.

Let’s start with the following basic definitions of popular science:

First, which Chinese medicines can be included in the quantity procurement? The "traditional Chinese medicine" that can be included in the quantity procurement mainly includes Chinese patent medicines and Chinese herbal pieces (including new-type pieces and formula granules) used in clinical practice in medical institutions.

Second, what is quantity procurement? Procurement with quantity is relative to centralized procurement, which can be understood as large-scale "group purchase" or "group purchase", that is, many hospitals form a "procurement consortium" to conduct similar "group purchase". At present, in areas where quantity procurement is implemented, the purchased products need to account for 60%-70% of the total usage, which is equivalent to a big "group purchase". Purchase with quantity, specify the purchase quantity, and the manufacturer will quote and negotiate, and the lowest price will win the bid. Enterprises can reduce the price of purchased drugs and increase the market share of products through market-oriented bidding with quantity, which is beneficial to both supply and demand sides and drug users.

Third, which institutions can carry out centralized procurement and quantity procurement? At present, it is mainly enforced in non-profit medical institutions under the supervision of medical insurance and medical and health authorities (note that it is not non-profit or non-profit). Social organizations such as retail pharmacies can also spontaneously organize "purchasing consortia" to carry out "group buying", which is referred to as "GPO purchasing" for short, but it is often not mandatory by policy.

Fourth, what does "4+7" procurement with quantity mean? It refers to the first batch of 11 pilot cities promoted by the state, including 4 municipalities directly under the central government and 7 provincial capital cities: Beijing, Tianjin, Shanghai, Chongqing, Shenyang, Dalian, Xiamen, Guangzhou, Shenzhen, Chengdu and Xi ‘an, which basically covers half of the domestic clinical drug circulation. These cities will take out more than 50% of the purchasing share every year, which has a great relationship with the market share of production enterprises and is a matter of life and death.

Therefore, once the country promotes the "4+7" or even nationwide procurement of traditional Chinese medicine, it will surely become a key event for Chinese medicine enterprises, which is expected to cause a major reshuffle of the Chinese medicine industry, and the industry must pay attention to it.

02

Why is it difficult to implement the procurement of traditional Chinese medicine for a long time?

Before answering this question, we must clarify two points:First, the centralized bidding and purchasing of proprietary Chinese medicines has been carried out around 2001, and the effect of reducing fees is very obvious, but it has not yet been included in the "4+7" procurement; Second, the centralized bidding and purchasing of Chinese herbal pieces. As early as 2001, the documents No.308 and No.309 jointly issued by five ministries and commissions in the State Council all proposed to "actively explore the centralized bidding and purchasing of Chinese herbal pieces".

However, it was not until 2018 that attempts were made in Shanghai, Gansu and other places, and the effect was not obvious; In July 2020, 12 provinces, including Shandong and Inner Mongolia, directly established a platform for the joint collection and purchase of Chinese herbal medicines, and prepared to carry out large-scale procurement activities of Chinese herbal medicines. However, the thunder and the rain are too small, and there is no more.

Why can’t centralized bidding or quantity procurement of traditional Chinese medicine products be promoted?

The apparent reason is that the overall purchase volume of Chinese medicine products without proprietary Chinese medicines is small, and the overall purchase volume of pieces of Chinese medicine in medical institutions nationwide is less than 56 billion yuan, which is only a fraction of the total purchase volume of chemicals and medical devices, and it lacks attention. But the deep-seated reason is that there are two bottlenecks, and there is no breakthrough for a long time:

The first is the standard issue.

Traditional Chinese medicine (TCM) is a practical weapon of TCM, and its personalized demand is very obvious. A large number of raw medicinal materials and even decoction pieces are agricultural and sideline products, which are non-standard products. You may say that the Pharmacopoeia has the standard of decoction pieces, but that is only the minimum quality threshold, and it can’t cover the complicated and changeable commodity circulation specifications of Chinese herbal medicines at all.

For example, 280 and 380 pieces of Lycium barbarum, Ningxia goods and Qinghai goods, new goods and old goods, although they all meet the pharmacopoeia standards, can they be regarded as the same commodity? Without a unified standard, how to divide the quality levels? If we simply use the Pharmacopoeia standard to evaluate products, it will undoubtedly lower the quality level of Chinese patent medicines and granules as a whole and destroy a large number of well-known brands of Chinese medicine.

Shanghai, Zhejiang and other places are going to separate the products using raw materials from GAP base or traceability base, but everyone in the industry knows that the construction of GAP base in China is difficult to land, and the construction of traceability base is just in its infancy. The concept is bigger than the essence. Can it be used as a criterion at this stage?

At the same time, even if you establish a commodity circulation standard, will this standard be recognized by both the supply and demand sides? How to run through the whole process of Chinese herbal medicine raw materials, Chinese herbal pieces, granules, production enterprises, products and demand side is a very difficult and grand project, which can not be straightened out by a single link.

The second is the price issue.　

The price problem is divided into three levels:

The first is how to define the cost of different quality Chinese herbal medicines. Origin, growth cycle, harvest time, content, appearance and processing technology will all affect its pricing. This problem is actually closely linked to the circulation standard and is an extension of the standard problem.

Secondly, the price fluctuation during the period of centralized mining. The nature of agricultural and sideline products of most Chinese herbal medicines leads to the reality that they still have to "eat by the sky". In the past five years, the price amplitude of Chinese herbal medicines in China has reached more than 18.5%. In August 2020, the same kind of forsythia was 55 yuan (kg price, the same below), and it will rise to 115 yuan in 2021; The raw land has skyrocketed from 11 yuan to 35 yuan. How do you let the successful bidder complete the distribution at the original price?

Allowing the price increase violates the rules of the game of winning the bid at a low price under the same quality, and how to accept the price increase basis? If the price increase is not allowed, the winning bidder will be miserable and it is very likely to lose money to perform the contract; If the roasted seeds and nuts add fuel to the fire and monopolize the raw materials of the winning products to raise the price, the enterprise will even lose the pants, and finally the severe consequences of "winning the bid is death" will not be ruled out.

More crucially, the higher the bid, the higher the price. At present, the principle of "bidding and bidding, the lowest price for supply" is generally adopted in raw material procurement of production enterprises, and all kinds of arrears and deduction of suppliers’ payment for goods have also existed for a long time, so as to minimize the cost of raw materials. If we really realize the so-called "genuine quality and conscientious processing" through centralized purchasing activities, and make the raw material sources and costs of those brand enterprises known to the world, we will inevitably face the embarrassing situation of "more recruitment and higher fees" due to the improvement of quality. Originally, centralized purchasing wanted to reduce prices and control fees, but as a result, the price of centralized purchasing rose sharply. Can the medical insurance department accept it? This is really a paradox.

To sum up, when designing the centralized collection activities of traditional Chinese medicine, the operators often fail to consider the complexity of traditional Chinese medicine products, especially in terms of standards and prices, and lack of fundamental countermeasures and convincing evaluation system, so there are many obstacles in the actual promotion, and most attempts eventually end in vain.

03

How to break the traditional Chinese medicine collection?

It is precisely because of the complexity of the centralized collection of traditional Chinese medicine that the procurement of traditional Chinese medicine in medical institutions has been in a blind spot or even a "gray zone" for a long time.

The so-called "high-end decoction pieces" and "selling granules with gold" such as Niuhuang, Cordyceps sinensis, Saussurea involucrata, etc. have long been an open secret in the industry, seriously damaging the principle of "openness, fairness and transparency" in drug circulation. Therefore, the centralized collection of traditional Chinese medicine must be implemented as soon as possible. But in the face of many practical difficulties, how to break the game?

The author believes that the key to the breakthrough of centralized collection of traditional Chinese medicine lies in rationalizing the industrial chain by using the big data platform of traditional Chinese medicine industry, and realizing the bottom logic of traditional Chinese medicine products from raw material production, processing, circulation to sales, thus achieving a closed loop.

In this closed-loop front-end, it is an order agriculture based on the concept of blockchain, which is directly linked to the annual orders of demanding enterprises. When the commodity codes are sold out, external capital cannot intervene at all to ensure the stability of supply prices; In the circulation link, it is the two-dimensional code traceability of the whole process; In the sales link, we encourage order agriculture and full traceability with high quality and good price, so that the traceability input of enterprises is worth the money; Finally, basic functions such as standardized warehousing and logistics and third-party testing should be completed.

In this closed-loop system, the construction of big data platform for Chinese medicine industry is very important and is the core grasper. All information such as origin information, product information, price fluctuation, employee data, supply and demand data, quality standards, etc. will be included in this big data platform, and the bottom layer will realize the whole process with unified coding.

Only after the above preparations are completed, can the centralized collection of traditional Chinese medicine have the basis for implementation, and can the original intention of the medical insurance department to raise quality control fees be realized.

I believe that the centralized collection of traditional Chinese medicine will surely make a breakthrough on this basis.

　　How many Internet accounts are associated with your mobile phone number? Did someone else use it to register an Internet account? What should I do if I find that my registered account is fraudulently used?

　　On July 21st, the Ministry of Industry and Information Technology officially launched the service of "One Certificate for General Enquiry 2.0" — — With the nationwide Internet account "one certificate for universal inquiry", users can inquire about the number of Internet accounts associated with their mobile phone numbers by virtue of the last six digits of their mobile phone numbers and ID numbers.

　　Protect user privacy and cover major applications.

　　It is understood that "One Certificate General Enquiry 2.0" is a national Internet account convenience inquiry service launched by the Anti-fraud Center of the Ministry of Industry and Information Technology on the basis of the "One Certificate General Enquiry" service of the national mobile phone card, in conjunction with Internet companies and telecommunications companies.

　　As a brand-new upgraded anti-fraud "sharp weapon", the "one-certificate-through-check 2.0" service has three main characteristics — —

　　Protect user privacy. In strict accordance with the requirements of laws and regulations such as Network Security Law and Personal Information Protection Law, the personal information of users is collected to the minimum, and desensitized display is carried out in the query page. The feedback query results only include the number of related Internet accounts, excluding personal information such as account names.

　　Covers major applications. The first batch of "One-Certificate Access 2.0" docked 11 applications of 8 Internet companies, including WeChat, QQ, Taobao, Alipay, Tik Tok, Aauto Quicker, etc., which can meet the query needs of most users at present.

　　The query method is convenient. When users use the service of "One Certificate General Enquiry 2.0", they can make convenient inquiries through various channels, such as micro-newspaper WeChat official account, anti-fraud special class WeChat official account of the Ministry of Industry and Information Technology, WeChat official account of China Information and Communication Research Institute, and Alipay’s "One Certificate General Enquiry" applet.

　　Prevent fraud by using Internet accounts.

　　In September last year, the Ministry of Industry and Information Technology launched the convenience service of "one certificate for universal inquiry" for national mobile phone cards. Users can inquire about the number of registered phone cards under their personal names by virtue of their resident ID cards. If there is any objection, they can inquire about the detailed information through the corresponding telecom enterprises and deal with it accordingly. By avoiding the risk of uninformed card handling, we can effectively safeguard the interests of the people and help crack down on telecommunication network fraud.

　　After a lapse of nearly a year, why did you launch the "One Certificate General Check 2.0" service again?

　　"In the early stage, the national mobile phone card &lsquo was launched through innovation; One-card general investigation ’ Service, convenient for users to check the number of calling cards under their names, and effectively prevent users from being unknowingly processed. " Sui Jing, director of the Network Security Administration of the Ministry of Industry and Information Technology, introduced that in practice, it was found that Internet accounts were "favored" by criminals because of their strong concealment and low application threshold, and have become one of the main criminal tools of fraudsters.

　　Some users reported that their mobile phone numbers were registered as Internet accounts without their knowledge. Due to the lack of a unified and convenient effective way to query their phone numbers related to Internet accounts, it provided convenience for criminals to register illegally, resell Internet accounts and use Internet accounts to commit fraud, and it also caused inconvenience to the broad masses to safeguard their vital interests.

　　In order to further promote the prevention and control of telecommunication network fraud, effectively safeguard the interests of the broad masses of the people, and fundamentally solve the problems such as the difficulty in querying and unbinding Internet accounts associated with telephone numbers under one’s name, on the basis of the previous "one-card universal query" service of national mobile phone cards, the anti-fraud center of the Ministry of Industry and Information Technology upgraded and developed the "one-card universal query 2.0" service, that is, the internet account query service associated with mobile phone numbers, which is convenient for users to query account details and handle services such as cancellation and unbinding.

　　More Internet companies will be docked to meet the query needs.

　　How to correctly use "one certificate for general inquiry 2.0"? After the user enters the query portal, fill in the mobile phone number, the last six digits of the ID number and the verification code on the query page to query. The query results will be replied within 48 hours through the unified SMS port of 10699000.

　　When the user inquires about the number of Internet accounts associated with his mobile phone number, which is inconsistent with the personal situation, he can click "Unbinding and Detailed Inquiry" to understand the processing mechanism of each enterprise. After passing the authentication, unbind or cancel the dissident account according to the guiding documents of the enterprise. If the problem still cannot be solved, you can call the customer service phone number of the corresponding Internet company.

　　According to reports, in the next step, the Ministry of Industry and Information Technology will connect more Internet companies, support a wider range of Internet application queries, and further meet the query needs of users.

The product strategy of Baidu Zhijia business group can be divided into three major areas: car, road and line: "car" is to provide smart car solutions for B-end car companies; "Road" is an intelligent solution for urban traffic; "Travel" is a travel service for C-end consumers.

On March 14th-16th, 2023, at the 4th Software-Defined Automobile Forum and AUTOSAR China Day in 2023, Wu Changlong, a senior engineer of Baidu Apollo Intelligent Technology Co., Ltd., said that Baidu’s technology accumulation in L4 field and the scale advantage of L2+ products promoted each other, and now it has realized the comprehensive layout of taxi-passenger car-urban transportation. On the technical level, the modular MCU and strong mainline software architecture can meet the needs of parallel development of different models and multiple projects on the same platform; With the support of agile development method and CICD, the output quality can be guaranteed while meeting the rapidly changing internal and external needs.

　

Wu Changlong | Senior Engineer of Baidu Apollo Intelligent Technology Co., Ltd.

The following is a summary of the speech:

Development and challenge of Baidu Apollo intelligent driving domain controller

In the past ten years, Baidu has accumulated rich technology and experience in the field of artificial intelligence, and now it applies these leading AI technologies to the automotive field. The product strategy of Baidu’s intelligent driving business group is laid out in three areas, which are car, road and line.

"Car" refers to the intelligence of cars. ASD, Baidu’s smart car division, is a tier1 role that provides full-stack smart car solutions for B-end car customers, including smart driving and smart cabin. At present, it has provided smart car solutions for 31 car companies, 134 models and more than 7 million cars. Baidu’s car is one of Baidu Apollo’s partners, and will be equipped with the full-stack intelligent solution of Baidu smart car, which will be listed this year.

"Road" refers to smart city traffic. At present, Baidu’s smart city transportation has provided solutions for 63 cities across the country, providing efficiency for urban transportation.

"Travel" refers to providing travel services for C-end consumers, which is known as radish running. Last year, Baidu released the sixth generation RT6, which has the ability to drive automatically on complex urban roads, and its cost reached 250,000 yuan. The mass production of RT6 will greatly accelerate the scale and commercialization of unmanned vehicles.

The above businesses complement each other. Baidu has accumulated rich technology and experience in L4 field, which can provide hot start for L2+ products. L2+ products feed back L4 products with the advantages of scale, and solve the long tail problem of L4 products’ final commercial landing.

Baidu’s smart car products include intelligent driving and intelligent cabin, including small-scale in-vehicle system and software and hardware integrated solution ARC. The intelligent driving domain controller is divided into two heterogeneous control chips, MCU and SOC. MCU deployed AUTOSAR protocol station, and developed CDD and application algorithm on this basis. The bottom layer of SOC is a system, and the top layer is the hardware poke layer and the middleware Apollo OS； developed by Baidu. Further up is the various atomic ability services of the algorithm; Further up are the various application logics of the algorithm.

Next, we will share the challenges we face in the development of intelligent driving domain controller MCU software based on AUTOSAR.

First of all, in recent years, there are many projects of Baidu’s intelligent driving domain controller, and it has already faced the situation that the same hardware platform supports multiple projects and multiple models for parallel development. A project needs to maintain independent software branches, and software changes, software optimization or repairs made in one project branch are always manually migrated to other project branches to ensure the consistency of product experience. And the coupling between software modules is very strong, and the change of one software module will often lead to the change of other modules, which will affect the whole body; In addition, it is necessary to migrate to multiple software branches at the same time, and the workload of maintenance increases exponentially with the increase of software complexity and projects.

In the stage of frequent changes in the demand of intelligent driving track, the time period is very short; However, there will be no reduction in the quality requirements for output. This challenges our software architecture. We urgently need a software architecture that can support multi-project parallel development and rapid iteration.

How to solve this problem? We found inspiration on AUTOSAR. The core idea of AUTOSAR is the decoupling of hardware and software. The bottom layer realizes the software functions that are strongly related to hardware, and abstracts them into standard interfaces for the upper layer. The upper ECU and the application layer are almost insensitive to the difference of the lower hardware, which makes the AUTOSAR architecture software migrate on multiple hardware platforms.

Secondly, the core idea of AUTOSAR is the modularization of software and standardization of interfaces. AUTOSAR is divided into hundreds of software modules, and the function definition of software modules is very clear, and the data between software is exchanged with the defined standardized interfaces. When the software of one module is changed, the influence on other software modules and even the whole controller software is controllable.

Platform of MCU software for intelligent driving domain controller

Our MCU platform software architecture refers to the idea of AUTOSAR. Firstly, a set of loosely coupled software architecture is needed. The so-called loose coupling means software modularization, and the function definition of each software module must be clear. The exchange interface between modules is standardized and managed in a unified file according to the architectural method of AUTOSAR.

The second is the strong mainline software architecture. Referring to the software architecture idea of AUTOSAR, we divide our MCU software into different softwares according to the actual business requirements. A hardware platform has only one software, and a project has a separate software. The interface between is predefined and cannot be easily changed. To ensure that a set of software can be combined with different software of multiple projects.

The actual operation method of this software architecture is:

First of all, the BSW project of AUTOSAR is strongly related to specific projects and models, such as the number of communication buses, the configuration of communication matrix, the configuration of diagnostic protocol stations, the configuration of network management, etc. These configurations are different for each model. Therefore, the BSW engineering code of AUTOSAR is divided into BASE software and CDD software (including IOO abstraction of various hardware and data intervention of sensors, etc.). These modules are only related to the hardware platform and have no direct relationship with the project. The application layer software isolates the differences of signal interfaces of various vehicles through the signal abstraction module, which makes most application layer software project-independent.

In addition, there are some special software modules, such as time synchronization module. All items of the time synchronization scheme in our domain are consistent; However, the cross-domain and vehicle-domain schemes have different projects. For this kind of module, we split the software of a module into two parts for maintenance, provided that the interfaces between the software must be well defined, so that multiple projects can share one software, and different BASE software can work normally together.

Under this software architecture, the methods of software management are different. A hardware platform has only one software warehouse, and each project has a separate BASE software warehouse. Only when the software is merged can the final MCU software output be obtained. Its advantage lies in that the mainline optimization is directly effective for each project. The challenge is how to ensure that the changes on the main line are not wrong for each project, which requires agile development and CICD to ensure.

Agile development of MCU software for intelligent driving domain controller

The software version delivery of the whole intelligent driving domain controller basically follows the traditional automobile micro-model development, from the initial demand input to software design, software development, software testing and overall acceptance, and a version lasts about 2-3 months. In the big cycle, we iteratively split the MCU software version into weekly agile development cycles.

The cycle of agile iteration in weeks can also be refined to the development iteration in days. Baidu has its own set of code management tools. When we push the code, it triggers the continuous integration compilation pipeline to get the compiled results and outputs. At the same time, the system will automatically trigger to pull the latest code from the library every night and push it to the CICD test server. The test server will simulate the upper computer to deploy the software to the domain controller of the test bench, which has a full set of sensor environment and simulated vehicle environment besides the physical domain controller. After the deployment, according to the pre-set test flow, the MCU software is matched with the SOC terminal to conduct a set of systematic tests.

After the test, the server finally collects the test results, and generates an email report and pushes it to the corresponding person. When you go to work the next day, you will know whether there is any problem with the previous day’s cooperation code. In addition to the bench test, we have a lot of driving tests every day, and the data generated in the test and the problems will be uploaded to the data center, and special managers will distribute the problems and data to the corresponding module leaders. After analyzing the data, the R&D personnel locate the problems, and then arrange the repair plan of the problems into the agile iterative process according to the priority, so as to carry out iterative development of the software, quickly deploy the new output to the R&D vehicle, and then carry out closed-loop verification.

At present, automakers pay more and more attention to software self-research, especially in the field of automatic driving. Some automakers choose Baidu as a supplier of software and hardware for intelligent driving systems; At the same time, I hope to participate in the development of some intelligent driving functions.

We also have some successful experiences in the project. First, OEM will generate the document of our intelligent driving domain controller, and then build an algorithm model to generate SWC articles in AR file format. And the final C code will be generated, and the ECU document will be given to Baidu. After we import the AUTOSAR development configuration tool, we can generate the technical engineering of MCU AUTOSAR and develop the software of MCU. Then compile it into a black-box project and give it to the OEM. The OEM will add the black-box project to the code generated by them for integration and compilation. After the compilation is passed, it will do its own module test. After the test is passed, it will give their model code compilation process to Baidu in the form of a black box. Then we will do the final integration, compilation and MCU software output, complete the integration test of the entire MCU domain controller, and deliver the test to the automobile factory, and then do the vehicle-level test.

　　This May Day holiday, a doctor "rushed to the hot search". He is Dr. Zhao Yipin from Zhoukou Maternal and Child Health Hospital in Henan Province.

　　On May 3rd, in Baiyun Mountain Scenic Area, Luoyang, Henan Province, an old man suddenly fainted during the tour. Dr. Zhao not only stepped forward to rescue him, but also silently guarded him until he regained consciousness. Later, Dr. Zhao also received an unexpected "gift".

　　Doctors save people during their tour and get free tickets for life in the scenic spot.

　　At about 13: 30 on May 3, someone suddenly called for help in the crowd visiting Baiyun Mountain Scenic Area, saying that someone had fainted. Just as the crowd was a little flustered, a tourist quickly went forward to check on the old man.

　　It turned out that the tourist’s name was Zhao Yipin and he was a doctor. After preliminarily judging the vital signs, he quickly cleaned up the food residue in the mouth for the elderly, kept the respiratory tract unobstructed and in a suitable position, and stayed with the elderly until she regained consciousness. At present, the elderly are in good health.

　　After the incident, after learning of Dr. Zhao’s kindness, the scenic spot quickly found him, exempting him from all the expenses of sightseeing and accommodation in Baiyun Mountain, and enjoying free tickets for life.

　　Emergency treatment of female sudden pulmonary embolism by doctors

　　At 9 o’clock in the morning of April 30, at the physical examination center of Shangqiu Central Hospital, a woman suddenly felt unwell. Duan Jing, a doctor on the way to the consultation, was hurriedly called by the nurse.

　　Duan Jing, Doctor of Physical Examination Center of Shangqiu Central Hospital:She said she wasn’t feeling well and wanted to go to the bathroom. I said, let’s go together with you. When she walked to the glass door, she suddenly fainted. I didn’t feel the pulse at that time, so I thought I had to have CPR for the first time.

　　Duan Jing helped the woman do an emergency cardiopulmonary resuscitation, but the woman’s teeth were clenched and she didn’t feel anything.

　　At this time, the emergency doctor on duty also came to the rescue. A few minutes later, with the help of many medical staff and enthusiastic citizens, the woman was pushed into the emergency room. After examination, it was learned that the woman was suffering from severe acute pulmonary embolism.

　　Wei Bing, Emergency Doctor of Shangqiu Central Hospital:The mortality rate of pulmonary embolism is 45%. She (patient) is now suffering from acute myocardial infarction, and the mortality rate is more than ten times. Especially her massive pulmonary embolism, if not treated in time, there will be no life in ten to twenty minutes.

　　Emergency doctor of Shangqiu Central Hospital Shi ZhenkaiThe chest compressions (cardiopulmonary resuscitation) done at the first time won valuable time for the patients.

　　At present, the woman’s vital signs have returned to normal and she is receiving further observation and treatment in the hospital.

　　The elderly station suddenly became ill, and the police drove to the hospital urgently.

　　At about 2 pm on May 3, the police station in Beidaihe Station, Hebei Province received a passenger’s request for help. A 70-year-old man suffered a heart attack and collapsed in the waiting room seat, hoping that the police would help him.

　　Police:Did you take your medicine? Do you have any medicine? Pills or something.

　　Family members of the elderly:I ate it.

　　Police:Just a moment, we are contacting (the hospital).

　　Old man:Thank you.

　　Police:Don’t worry, our car will pick you up and take you to the hospital.

　　Old man:Oh, thank you so much.

　　Police:Now you just talk less, don’t talk, don’t worry.

　　In order to gain medical treatment time, after obtaining the consent of the elderly and their families, the police used police cars to send the elderly to the hospital for treatment. Due to timely treatment, the elderly are now in good health.

　　Peng Zhiqiang, a policeman from Beidaihe Station Police Station:Passengers who have a special medical history or are physically unfit for long-distance travel are advised to travel with their relatives and friends when taking the train, and at the same time, take the commonly used essential medicines with them. In case of emergency, please contact the railway staff and the police for help in time.

　　As a new favorite of the family, computers have entered the homes of ordinary people. However, due to the lack of basic knowledge of home computers by ordinary users, some seemingly casual actions may directly lead to instant "paralysis" of computers and even damage human health.

　　Misunderstanding 1 Clean the screen with anhydrous alcohol

　　When the monitor is used for a long time, it is inevitable that there will be dust and stains. Many users think that alcohol, especially high purity (above 95%) is the best cleaner. On the contrary, there is a special protective coating on the screen of the current flat panel display to prevent static electricity and dazzle light. If alcohol is used for cleaning, it is easy to destroy the coating, but the display effect of the display is greatly reduced. In fact, the screen of the monitor, including its shell, cannot be cleaned with solvents such as alcohol, gasoline and washing powder. There is a special cleaner for monitors in the supermarket. Don’t use ordinary thick towels when cleaning the screen, you can wipe it with glasses cloth with better texture.

　　Myth 2: The chassis is exposed to heat.

　　When the computer is running, especially in summer, its heat dissipation is very large. Some computer enthusiasts directly open the chassis in order to strengthen heat dissipation and facilitate hardware disassembly. Although this method solves the problem of heat dissipation, the "gut opening" of the chassis exposes the hardware, which is easy to accumulate dust, and dust will become the "killer" of the computer over time. In addition, this practice is also harmful to human health. As we all know, CPU, motherboard and power lamp hardware are all high electromagnetic radiation sources, and the chassis can shield most electromagnetic radiation. If you let your body directly "receive" high electromagnetic radiation just to dissipate heat, it will not pay off.

　　Myth 3: Cover the dust cover after shutdown.

　　When a new computer enters the home, many people will protect it, especially paying attention to dust prevention measures. Dust cover is of course one of the necessary items, but it is not advisable to cover it immediately after shutdown. Although the mainframe has stopped running after shutdown, there is still a lot of heat in the chassis and the back cover of the monitor, and the temperature of various electronic components is very high, which needs to be cooled gradually. If you cover it with a dust cover immediately, it will easily hinder the heat dissipation of the hardware and even seriously affect its service life. It is best to turn off the machine for 1-2 hours and wait until the heat in the chassis is basically dissipated before using the dust cover.

　　Misunderstanding 4 Hot-swappable peripherals with electricity

　　When performing various hardware operations, some users often plug and unplug the mouse, keyboard and various serial and parallel port devices of PS/2 interface in standby mode. These operations seem normal, and actually have a certain "lethality" to the computer host, which may cause the system or hardware to work abnormally, and may even cause damage to the hardware interface or motherboard. In fact, except for USB, IEEE1394 interface and serial hard disk, all kinds of peripherals of ordinary desktops are not hot-swappable with electricity, so it is suggested that you must operate correctly when the power is turned off to avoid unnecessary losses.

　　Beijing, May 31st, the client of Zhongxin. com, starting from tomorrow, the time will enter June. At the same time as the hot summer, there are a number of favorable policies, such as high-temperature allowance and new rules for online car rental, which will bring real "coolness" to your summer in terms of income and travel.

　　High temperature allowance began to be distributed.

　　Every summer, the distribution of high temperature allowance is concerned by the public. In most parts of China, with the arrival of June, the money will be credited to the workers’ accounts one after another.

　　According to the Management Measures for Heatstroke Prevention and Cooling Measures revised in 2012, if the employer arranges the workers to engage in outdoor open-air operations in hot weather above 35℃ and cannot take effective measures to reduce the workplace temperature below 33℃, it shall pay the workers a high-temperature allowance.

　　Judging from the distribution time of high temperature allowance, there are also differences in different places due to differences in climatic conditions. For example, the distribution period in Beijing, Shanxi and other regions is from June to August; Jiangsu, Shanghai, Gansu and other places are from June to September; Guangdong, Guangxi and other places are from June to October.

　　In addition, Jiangsu, Tianjin and other provinces also raised the high temperature allowance this year.

　　The network car is included in the taxi service assessment system.

　　The safety and convenience of taxi travel are also concerned by the public. The "Measures for the Assessment of Taxi Service Quality and Credit" will be implemented on June 1, and the online car will be included in the taxi service assessment system, but the assessment of the online car driver will only be "returned to the furnace".

　　Specifically, the "Measures" will include the new format of the network car in the assessment, and clarify that both the network car and the cruise car need to carry out the service quality reputation assessment. In the indicator setting, the common requirements of the network car and the cruise car are considered, and according to the unique operating service characteristics of the network car, the indicators such as data access and operating service information disclosure are tailored.

　　In addition, the "Measures" also adjusted the distribution setting of the assessment scores of taxi companies, increased the assessment scores of providing operational services for passengers and other matters, and guided drivers to actively improve service quality.

　　It is worth mentioning that the "Measures" stipulate that drivers should be assessed for compliance with laws and regulations, safe production, business behavior and operational services. If taxi drivers score less than 3 points during the assessment period, they should receive training as required.

　　English "national standard" will be implemented.

　　How to evaluate the English level of China people? On June 1st, the first English proficiency assessment standard for English learners in China, China English Proficiency Rating Scale, will be launched.

　　It is understood that the scale was released by the Ministry of Education and state language commission in April, which graded English learners and users in China in detail. Among them, the English language ability of English learners and users in China is divided into one to nine grades from low to high, which are classified into three stages: basic, improvement and proficiency.

　　According to the relevant person in charge of the Examination Center of the Ministry of Education, the scale is like a competency scale, which will play an active role in improving the quality of examinations, promoting the docking of domestic and foreign examinations, promoting multi-evaluation and feedback teaching, and is conducive to achieving "quantity balance".

　　Drone access conditions are reduced.

　　In recent years, the unmanned aerial vehicle market in China has grown rapidly, and its application in agriculture, electric power, surveying and mapping, security and other fields has become increasingly mature. However, the relevant regulations on unmanned aerial vehicles engaged in commercial flight activities have always been a blank.

　　From June 1st, the Administrative Measures for Operational Flight Activities of Civil Unmanned Aerial Vehicles (Provisional) issued by the Civil Aviation Administration will be implemented soon. The "Measures" standardize the access and supervision requirements for unmanned aerial vehicles to engage in operational general aviation flight activities, and enterprises engaged in operational flight activities will be legal and compliant from now on.

　　What impact will A-shares enter Morocco?

　　In June, there is another financial event worthy of attention.

　　On May 15th, MSCI (Morgan Stanley Capital International Company, also known as "morgan stanley capital international Company" in China) announced the adjustment results of semi-annual index constituent stocks, showing that 234 A-shares were confirmed to be included in the MSCI index system and officially implemented on June 1st.

　　According to the data, MSCI index is compiled by Morgan Stanley International Capital Corporation (MSCI), which is often used by mainstream international funds as investment guidance or tracking index, and their own ETF funds (transactional open index funds) are allocated according to MSCI index. From next year, overseas funds can also purchase A shares directly through MSCI index.

　　In the eyes of the industry, the participation rate of overseas institutional investors will continue to rise after A shares are included in the MSCI index. In the medium and long term, the A-share market will become more mature, the liquidity will increase, and the market trend will gradually be dominated by short-term market noise and driven by basic factors.
