"hanging wire for pulse diagnosis" of satellites in orbit

■ Lu Binghong Zhang Mi Liberation Army Daily reporter Wang Lingshuo

On the eve of the Spring Festival this year, Xi ‘an Satellite TT&C Center successfully completed the health status assessment of 52 Beidou navigation satellites. Through the "physical examination" of the Beidou navigation satellites in orbit, the scientific and technical personnel ensure that the key technical indicators of these satellites meet the requirements of providing various services normally and continue to maintain good working conditions in orbit.

The reason for the "physical examination" of satellites is that satellites in the past days will sometimes have "minor ailments and pains" or even "incurable diseases", which will affect business applications and lead to the failure of the whole satellite. China’s space science and technology workers are deeply involved in the on-orbit diagnosis and maintenance technology of spacecraft to realize early detection, prevention, diagnosis and treatment of satellite faults.

Satellites in orbit are so delicate.

When it comes to space flight, people often think of the rocket launch that attracts people’s attention and rises in flames. In fact, this is only the prelude to the space mission, and the work really begins when the satellite enters the scheduled orbit and is put into business application in space.

Satellites are the largest number of spacecraft launched by human beings, accounting for more than 90% of the total number of spacecraft launched, and have considerable uses in meteorological monitoring, communication and navigation, disaster prevention and mitigation and other fields. As a complex system composed of thousands of components, satellite has more and more functions and greater value with the continuous development of technology. The times of detection, diagnosis, calculation and treatment, control and disposal, and the telemetry parameters that need to be downloaded and monitored are also increasing. This puts forward higher requirements for the accuracy and stability of the ground control system. However, satellite technology is complex and dense, and it is in a complex space environment, so the probability of failure exists objectively and there are various types.

In 2018, shortly after the latest model of meteorological satellite GOES-17 in the United States was put into orbit, the cooling system failed, which made the imaging system of this satellite unable to provide satellite images in near infrared and infrared channels. Satellites can’t get infrared cloud pictures taken at night in time and effectively, and they become "blind" at night.

Coincidentally. In July, 2019, the European Galileo satellite navigation system lost all 24 satellites due to the timing error of the precise timing facilities located in Italy, and the whole system was once paralyzed. It was not until a week later that the system fully resumed service.

At the same time, satellites operate in a vacuum, weightlessness, ultra-low temperature, strong radiation and full of unknown factors for a long time, and space junk and solar activities will bring trouble and even fatal damage to satellites. Therefore, it is inevitable that there will be some technical problems during the life of the satellite.

What’s more, the cost of modern satellites is high, and with the launch cost, the cost of a satellite is often calculated in hundreds of millions of yuan. If the technical failure of the satellite is not eliminated in time or cannot be eliminated, huge economic losses will be inevitable. Therefore, once the running satellite fails, all countries will spare no effort to rescue the satellite and minimize the loss.

Troubleshooting with "Hanging Wire Pulse Diagnosis"

When there is a problem with the machine on the ground, people can locate and eliminate the fault through various methods. For satellites in orbit, it is the only way for technicians to master the attitude and working state of satellites by means of electromagnetic wave transmission.

The so-called satellite fault diagnosis and maintenance means that when the satellite fails, in order to avoid the paralysis or functional failure of the whole system caused by the failure of some components, the state detection, fault diagnosis, health assessment and other work are carried out quickly through telemetry data, the current state and future "illness" trend of the satellite are analyzed, the satellite fault level is defined, the fault location and cause are determined, and the treatment is carried out in time. This is just like the plot of "hanging the wire to feel the pulse" in Chinese classical novels and traditional operas. With this core technology, ground measurement and control personnel can detect tiny faults hidden inside the satellite as soon as possible, and after fault identification and fault isolation, take corresponding maintenance support or fault degradation treatment, so as to avoid catastrophic failures of the satellite and ensure the safe operation of the satellite.

The diagnosis and maintenance technology of spacecraft is developed with the realistic requirements of spacecraft mission expansion, control accuracy improvement and working life extension. The traditional space powers, represented by the United States and Russia, started earlier and have done a lot of research and practice in this field.

In the 1960s, with mankind gradually entering the space age, the spacecraft diagnosis and maintenance technology was also launched. Due to the limitation of technical conditions, component quality and design level at that time, people can only rely on simple instruments to monitor some key parameters of the satellite with single signal threshold state in this period to judge whether there is a fault. This method provides a certain guarantee for the on-orbit operation of early human spacecraft. At this stage, the average life of spacecraft is generally short. In manned space mission, the safety guarantee system of the system is composed of state monitoring, ground expert consultation and astronauts’ direct participation, and the autonomy, real-time and reliability of the spacecraft fault detection system are also poor.

Since 1970s, with the development of technology and the improvement of component quality, design level and process level, the diagnosis and maintenance technology based on hardware redundancy has been widely used in the field of spacecraft. The diagnosis method has also developed from simple threshold judgment to making full use of various dynamic testing technologies, monitoring technologies and information processing technologies, which has greatly extended the average life of spacecraft.

During the Apollo mission to the moon, the United States first established a flight anomaly analysis and evaluation system. The system includes flight fault monitoring and processing, flight state evaluation, flight data standardization, fault ground simulation, etc., and all emergency life-saving parameters are equipped with triple repetitive sensors and dominant voting logic circuits, which obviously enhances the autonomy and reliability of the spacecraft fault detection system.

In the 1980s, artificial intelligence research flourished, and knowledge-based diagnosis and maintenance technology, especially expert system technology, began to be widely used in the aerospace field. Among them, several intelligent fault diagnosis technologies based on expert system and testability model data-driven are the most representative. At the same time, the appearance of highly complex and reusable spacecraft such as the space shuttle makes the fault diagnosis and maintenance system not only have the distribution of modular functions, but also have the integrity of coordination. With the gradual construction and on-orbit operation of the International Space Station, its fault diagnosis and maintenance system has further greater variability, better adaptability and stronger robustness, and gradually develops in the direction of self-management, so that the failed space station can continue to complete its scheduled tasks without affecting its performance.

"Star Shepherd" guards "China Star"

The management level of long-term in-orbit satellites largely determines the realization of satellite efficiency. Since China launched the first artificial earth satellite in 1970s, the spacecraft on-orbit management and control technology has made great progress through the unremitting efforts of several generations of scientific and technological personnel.

As early as 2007, relying on Xi ‘an Satellite Monitoring and Control Center, China began to build a national-level "satellite general hospital"-spacecraft on-orbit diagnosis and maintenance center, and immediately carried out major scientific research projects in the field of spacecraft on-orbit fault diagnosis and maintenance.

With the increasing number of satellites in orbit, China urgently needs to further improve its on-orbit diagnosis and maintenance capabilities. In 2014, Xi ‘an Satellite TT&C Center established China’s first on-orbit fault diagnosis and maintenance laboratory. Through the research on early identification and location technology, on-orbit fault simulation and maintenance technology, on-orbit reliability growth and life extension technology, the independent innovation ability of on-orbit fault diagnosis and maintenance of spacecraft in China was further improved, which promoted the sustainable development of China’s aerospace engineering and became a solid foundation support for the continuous increase of the number of on-orbit satellites in China.

By collecting and sorting out thousands of fault cases at home and abroad and summarizing nearly one million pieces of diagnosis knowledge, the center independently developed an expert system for spacecraft fault diagnosis, which effectively solved the problems of late discovery, slow analysis and difficult positioning of spacecraft micro-faults.

In addition, starting from Beidou satellite, they independently developed a satellite health assessment system, established a relatively complete three-level health assessment index system of "sub-system, key single machine and key performance", put forward a meta-knowledge construction method of health assessment for single satellite in orbit, and built a detailed "physical examination file" for each satellite. The evaluation conclusions of the satellite system put forward targeted countermeasures and suggestions for the follow-up satellite on-orbit management from the aspects of key components’ operation state, abnormal prevention and response, space environment change and load efficiency guarantee, which effectively ensured the safe and stable operation of Beidou system in orbit.

As the largest long-term management center of spacecraft in China, Xi ‘an Satellite TT&C Center has been managing China’s satellites in orbit for a long time, taking on the on-orbit management tasks such as daily telemetry monitoring, orbit control, fault diagnosis and maintenance, and it is a veritable "big housekeeper" of China satellites. Although the "China Stars" are in space, they are not alone, but are always under the care of the "Star Shepherd".

In the future, Xi ‘an Satellite TT&C Center will also deeply and extensively apply artificial intelligence technology, comprehensively improve the level of diagnostic and maintenance capabilities, and lay a solid technical foundation for the on-orbit management of the "giant constellation" in the future.

　　Xinhua News Agency, Beijing, November 5th: The third step of Beidou, when the world is shocked – the secret of Beidou-3 global networking satellite

　　Xinhua News Agency reporters Hu Zhe, Bai Guolong, Yu Xiaojie

　　The third step of Beidou is to surprise the world!

　　On November 5, the Beidou-3 satellite, which has attracted worldwide attention and people’s expectations, opened the prelude to global networking. According to the goal of "completing the launch of 18 satellites around 2018, taking the lead in providing basic services to countries along the’Belt and Road Initiative ‘; achieving a global network of 35 Beidou satellites in 2020, with the ability to serve the world", China’s Beidou is making great strides to the world.

　　How will Beidou-3 achieve the "triple jump" from domestic to regional to global satellite navigation? Where is the technological lead? What surprises will it bring to people and the world?

　　Domestic, Regional, Worldwide: Beidou Navigation Achieves Historic "Triple Jump"

　　As one of the three major satellite navigation systems in the world, the Beidou satellite navigation system that travels in the earth’s orbit, from Beidou-1 to Beidou-2 to provide regional services, and then to Beidou-3 global network, continuously providing accurate and high-quality services for the majority of users.

　　"You want me to have, you want me to be excellent, serve human society and benefit the general public." Since December 27, 2012, the Beidou regional navigation system officially provided regional services, and the Beidou system has received more and more attention from countries.

　　In January 2017, the Beidou-2 satellite project won the special prize of the National Science and Technology Progress Award. Yang Hui, chief engineer of the Beidou-2 project satellite system of the Aerospace Science and Technology Group, said that the Beidou-2 satellite project took eight years of development and construction, got rid of dependence on foreign satellite navigation systems, and achieved a historic "triple jump".

　　"China’s Beidou, the world’s Beidou." It is turning from a blueprint into a reality. Xie Jun, deputy chief designer of the Beidou No. 3 project and chief chief satellite designer of the Fifth Academy of Aerospace Science and Technology Group, introduced that long before Beidou-2 officially provided regional navigation and positioning services, our country began the demonstration and development of the Beidou-3 global navigation system, and determined the development goal of building an independent, open, compatible, technologically advanced, stable and reliable global satellite navigation system.

　　Xie Jun said that compared with the Beidou-2 regional system, the Beidou-3 service area will be expanded to the world, and at the same time, key technological breakthroughs such as downlink navigation signal upgrade and transformation have been achieved, achieving a smooth transition with the Beidou-2 downlink navigation signal. On this basis, new navigation signals have been added to provide users with better services.

　　It is reported that the construction of high-performance, high-reliability Beidou global satellite navigation system is one of the 16 national science and technology major special projects in the medium and long-term development plan of our country’s science and technology field.

　　High Precision, High Reliability, High Insurance: Beidou-3 Technological Breakthrough

　　Chi Jun, commander-in-chief of the Beidou-3 satellite of the Fifth Academy of Aerospace Science and Technology Corporation, told reporters that just as water and power outages affect urban life, once the satellite navigation service fails, not only the country’s economic operation will be greatly affected, but also people’s lives will be greatly affected. This also puts forward demanding requirements for the reliability of the satellite navigation system. Overall, Beidou-3 has the characteristics of high precision, high reliability, high insurance, and multi-functionality.

　　- High accuracy. On the basis of the performance of Beidou-2, Beidou-3 was designed with the goal of the third-generation GPS navigation satellites that had not yet been launched and the design indicators of the European Galileo navigation system.

　　The positioning accuracy of the Beidou-3 global navigation system will be greatly improved, reaching the level of 2.5 meters to 5 meters. After completion, the Beidou global navigation system will provide civilian users with free positioning services with an accuracy of about 10 meters, 0.2 meters per second speed measurement service, and will provide paid users with a higher accuracy level of services. The satellite design life is more than 10 years. With the Beidou ground-based enhancement system providing initial services, it can provide meter-level, sub-meter-level, decimeter-level, and even centimeter-level services. By then, China’s Beidou accuracy will be comparable to that of the US GPS.

　　- High reliability. Beidou is a system engineering. Every time a user enjoys the service of the Beidou system, it must ensure that there are at least four satellites to provide services; Beidou is a global coverage system, and at least more than 20 satellites need to provide stable services at the same time. This feature determines that the Beidou system requires higher quality reliability than a single star, and more stringent requirements for product reliability. Beidou is also a system whose inherent properties require continuous operation. The signal cannot be interrupted, and the system must be continuous, stable, intact and reliable.

　　- High insurance. According to Wang Ping, chief designer of the Beidou-3 satellite of the Fifth Academy of Aerospace Science and Technology Corporation, the Beidou satellite global navigation system, as a large-scale system project, adopts multiple reliability "reinforcement" measures to maximize the insurance factor of the system.

　　For example, after the system is completed, the number of operating satellites is greater than the number of satellites necessary for service; at the same time, the Beidou-3 satellite also adopts a number of measures such as software redundancy, fault self-diagnosis, and fault self-repair to ensure system reliability and greatly enhance the user experience.

　　- Multi-function. In addition to features such as short messages, China’s Beidou can also send users’ location information, so that others can know the user’s situation, and better solve the problem of who, what, and where. Combining text messages with navigation is a major feature of the Beidou satellite navigation system. One end point can have both navigation and communication.

　　Far away? Close at hand! Beidou service is everywhere

　　Ofo’s small yellow cart and Beidou Navigation jointly launched the Beidou smart lock; the small blue bicycle used the Beidou foundation enhancement system to achieve meter-level positioning, even in the shade of the tree, there will be no "drift"… In order to report "where I am" more accurately, shared bicycles have been connected to the Beidou high-precision time and space positioning service one after another.

　　Shared bicycles are just one of the applications that Beidou has in the near future to serve people’s livelihood. From emergency rescue and disaster relief to precision agriculture, from fishery broadcasting to smart housing management… In recent years, various high-precision location-based service products of Beidou satellite navigation have been widely used in all aspects of the national economy and people’s livelihood under the new model of "Beidou + Internet + Other Industries".

　　The recently released White Paper on the Development of China’s Satellite Navigation and location-based service industry (2016) shows that the total output value of our country’s satellite navigation and location-based service industry reached 211.80 billion yuan in 2016, an increase of about 22.06% over 2015. Beidou’s contribution rate to the core output value of the industry reached 70%, and our country’s satellite navigation and location-based service industry has broad prospects.

　　"At present, Beidou applications in our country have entered a stage of rapid development. With the combination of satellite navigation technology with the Internet of Things, big data, cloud computing and other technologies and fields, satellite navigation and location-based services have become important strategic emerging industries in our country," said Min Yiren, deputy director of the National Bureau of Surveying, Mapping and Geographic Information.

　　In Hainan Wenchang Qinglan Port, the Beidou navigation end point is the standard for fishermen to go to sea: the operation can be monitored in real time, the fishing boat can be alerted at any time when it is in danger, and the weather forecast and early warning notification can be listened to at sea. Beidou has become the "clairvoyant", "downwind ear" and "amulet" in the mouth of fishermen…

　　Yu Xiancheng, president of the China Satellite Navigation and Positioning Association, said that Beidou technology has jumped out of the category of single navigation technology. Under the urgent needs of various industries such as urban gas, urban heating, power grid, water supply and drainage, the National Beidou Precision Service Network has provided Beidou precision services for various industry applications in more than 400 cities across the country, effectively promoting the optimization and improvement of smart city infrastructure.

　　Seventeen, spinning and jumping, through to Paris

　　On October 6th, Liu Qingyi, a teenager from China, won the gold medal in the women’s break dance group of Hangzhou Asian Games. She is known as "671". After winning the championship, many people are asking "What is the name of the champion?" This is just like the young man’s favorite sport, which has just entered the elegant hall. At the end of 2020, the International Olympic Committee agreed to add break dancing as an official event of the Paris Olympic Games. In just a few years, China’s break dance has developed rapidly and is entering its best era. Break dancing, skateboarding, e-sports and so on, a number of emerging projects are entering the sports arena, waiting to shine and lead the future.

　　Youth dance steps fly, and every rhythm exudes confidence and courage!

　　Eighteen, Ding Xia cried, and the victory was hard-won.

　　On October 7th, China women’s volleyball team defeated Japanese women’s volleyball team in Hangzhou Asian Games and successfully defended its title. The topic of "Ding Xia is crying" once reached the top of Weibo Hot Search. The veteran of the three-time Asian Games couldn’t hold back at this moment, and netizens also broke through the defense. Those who accompanied China women’s volleyball team all the way knew how many ups and downs and hardships this glorious division had along the way. However, regardless of adversity or prosperity, they never give up, the veteran sticks to it, the teenager grows up, and the "women’s volleyball spirit" passed down from generation to generation shines.

　　Not afraid of hardships, she will always be our "China girl"!

　　Nineteen, the most beautiful China red, deep love for national conditions.

　　On the tennis court, Zheng Qinwen said after winning the women’s singles championship that honor belongs to the country; After Zhang Zhizhen won the men’s singles championship, he waved the national flag to celebrate. In this Asian Games, bright China red can be seen everywhere inside and outside the stadium, and songs such as "Singing the Motherland" and My People，My Country resounded through the Asian Games venues, and the deep love for the country was always felt. Qiu Xiuping, the rowing girl who won the first gold medal, helped the staff to fold the national flag before leaving. After the victory, the athletes cheered with the national flag, sang along with the national anthem, fingered the national flag on their chests, and ran hard and bravely pursued their dreams, vividly showing the spirit of China athletes in the new era, which was touching and inspiring.

　　Five-star red flag, you are my pride; Five-star red flag, I bless you and I am proud of you.

　　Thank you for Hangzhou. It’s hard to say goodbye. I’ll see you in Paris.

　　In the Hangzhou Asian Games, the China sports delegation won 201 gold, 111 silver and 71 bronze, which achieved the goal of double harvest of competition results and spiritual civilization. Looking back on the Asian Games, what impressed us was not only the moment when China athletes challenged their limits and surpassed themselves to win gold medals, but also the touching moment when they went all out for the honor of the motherland, fought hard for their love, made selfless contributions to the team and burst into tears for their friendship. Those glittering characteristics and qualities inside and outside the stadium are the best interpretation of Chinese sportsmanship.

　　On the occasion of departure, the Asian Games family was reluctant to part with Hangzhou, where a sports event with "China characteristics, Asian elegance and splendor" was presented to the world.

　　Based on Asia, bid for the Olympic Games. Thank you, Hangzhou, for your hard work. See you in Paris!

　　(Hangzhou, October 8 th)

August 5, Beilun, Ningbo.

In the "place where dreams begin" of Geely Bo Yue, FX11 ushered in the world’s first show, and has a formal name-Bo Yue L. As Gan Jia, CEO of Geely Automobile Group, said: "Innovation is the gene flowing in Geely’s blood." Geely positioned Bo Yue L as an "innovator of intelligent SUV".

As an innovator, Bo Yue L aims to create a landmark work of China intelligent SUV, and "L" stands for Larger, Luxury and Legend. This time, how does Geely interpret comprehensive innovation?

Bo Yue Family: Innovators in Automobile Industry

In 2016, Ningbo Beilun and Bo Yue went public, and the phrase "Hello, Bo Yue" created a new era of intelligent connected SUV.

Today, people still talk about this "the most beautiful China SUV", and Bo Yue is the benchmark of independent compact high-end SUV in terms of design and quality. Bo Yue is Geely’s pioneering work to open a new era of SUV strategic development, and it is also a key product to help Geely become the global leader of China brand.

"Innovating technology and popularizing the public" is the mission of every generation of Bo Yue to innovate the industry, and the global market has also given a warm response to Bo Yue family: in six years, the cumulative global sales of Bo Yue family has exceeded 1.4 million. It is worth mentioning that, as the first SUV of China brand to fully export products, technology and management, Bo Yue has achieved localized production in Belarus, Malaysia and other places, and sold well in 30 countries and regions, ranking first in many cities, setting a benchmark for China brand globalization.

On August 5th, Ningbo Beilun, the first generation of Bo Yue listed in 2016, was the origin of Bo Yue’s takeoff. Bo Yue L starts from the innovation here, with five smart technologies and ten hard cores as standard, and once again comprehensively innovates the smart SUV standard.

Innovation: Redefining the new standard of intelligent SUV

Bigger, flagship, and the return of the king, Bo Yue L bears multiple missions.

According to the data, Bo Yue L, as the flagship strategic product of "Smart Geely 2025" and "Building a Car with Comprehensive Architecture", has innovated the five world-class intelligent technologies of intelligent architecture, intelligent hybrid, intelligent driving, intelligent space and intelligent safety while inheriting the five global genes of CMA architecture.

Taking the intelligent architecture as an example, in the words of Fan Junyi, general manager of Geely Automobile Sales Company, building a car is no longer as simple as color TV+refrigerator+sofa. Therefore, the comprehensive and innovative CMA architecture gives Bo Yue L the mechanical quality of a luxury brand.

Let’s talk with numbers: Bo Yue L has a braking distance of 35.8 meters in 100 kilometers, and the limit speed of Elk test is 78 kilometers per hour, which is comparable to the performance of racing car, which is the "talent" brought by CMA architecture.

In addition, in terms of intelligent driving, Bo Yue L has achieved "leapfrog", and the new car is equipped with NOA lane-level automatic driving navigation system initiated by Geely. According to reports, this system has centimeter-level high-precision positioning, man-machine co-driving VR navigation and full lane dynamic monitoring technology. Under the blessing, it can achieve full coverage of more than 100 high-speed driving scenes. It is estimated that the price range of Bo Yue L is between 140,000 and 180,000. It is indeed a subversive innovation to be equipped with such an advanced intelligent driving assistance system.

Bo Yue L didn’t stop there. While realizing the innovation and popularization in five core areas, it started with Geely Galaxy OSAir version, 13.2-inch central control vertical screen, 10.25-inch digital LCD instrument, L2 intelligent driving assistance system, 540 transparent chassis of God’s eye, remote control of mobile APP, aerospace 7-series aluminum alloy crash beam, 178LX digital rhythmic LED headlights, racing brake system and integrated boron steel thermoformed door knocker.

Redefining the access standard of smart SUV market-Bo Yue L is serious.

Chinese aesthetics: the blending and innovation of traditional culture

In the digital age, how to inherit Chinese aesthetic expression? How to integrate the sense of intelligence, technology, futurism and oriental aesthetics to interpret the spirit of blending and innovation in China traditional culture?

As the first mass-produced car based on the "Vision Starburst" concept car, Bo Yue L has adopted a brand-new design concept of "Digital Symphony Technology Aesthetics", retaining the dynamic and cool design style and strong sense of digital technology of the concept car. It not only inherits the product design style of "Technology Geely 4.0", but also integrates intelligent technology, futuristic sense and digital concept.

Bo Yue L adopts mainstream designs such as two-color body and suspended roof. The body size is 4670×1900×1705mm, and it has a leading wheelbase of 2777 mm. Combined with the short front and rear suspension design, it forms a leading axle length ratio of 59.5%, achieving a win-win situation of stable handling and ample practical space.

What is striking is Bo Yue L’s sharp and slender arrow modeling design. The digital arrow LED runs through the taillight and consists of 290 LED light-emitting units. The ultra-red LED with a wavelength of 633nm echoes the headlight group at a distance. It is full of digital sense of science and technology and is very tense. I believe it will be welcomed by the younger generation who pursue individuality.

In terms of power, the Bo Yue L fuel version will be equipped with 1.5T and 2.0T turbocharged engines respectively, matching the 7-speed dual-clutch gearbox.

The hybrid version of the car is also divided into two versions: oil-electric hybrid and plug-in hybrid, and is equipped with the Geely Lei Shenqing Hi·X hybrid system. Full-oil and full-charge comprehensive battery life reaches 1300 kilometers, and the fuel consumption per 100 kilometers is as low as 4.2 liters.

In addition, draw a key point: Bo Yue L is intimately equipped with an antiviral door handle with a sterilization rate of over 99%, which can inhibit the growth of bacterial viruses for a long time, which can be described as intimate and practical at present.

Write at the end:

Gan Jiayu, CEO of Geely Automobile Group, said at the press conference: "Innovation is the gene flowing in Geely’s blood. Bo Yue L has benefited users from the latest, most popular and best-used intelligent technologies, injecting ever-evolving vitality into smart cars. "

This can’t help but remind people of the song "Life in Full Bloom" brought by Teacher Wang Feng at the press conference:

I want a life in full bloom, just like flying in the vast sky, just like walking through the boundless wilderness, with the power to break away from everything.

Evolution brings vitality, which is innovation.

　　[car home Information] On April 11th, we learned from WeChat official account, the official WeChat of Xiaomi Automobile, that it gave a "13th round" centralized answer to recent questions from netizens, including (|) Pro models with optional electric spoilers, why can’t physical buttons be installed, does Xiaomi SU7 have an in-car camera, can it be turned off to protect privacy, can it be safely handed over to the vehicle for operation during automatic parking, and the driver is completely indifferent, as follows:

1. Xiaomi SU7 Pro model can be equipped with electric spoiler (tail wing). Why can’t it be equipped with physical buttons?

　　Xiaomi SU7 Pro is not equipped with electric spoiler (tail wing) and air suspension by default. In the initial product design, only two physical buttons for air conditioning temperature and air volume adjustment were reserved in the center console. Recently, we learned that users of Xiaomi SU7 Pro want to add physical buttons to adjust the electric spoiler (tail) after installing the electric spoiler (tail). After several rounds of careful discussion and production scheduling verification, Xiaomi Automobile Product Team has made the following adjustments: Xiaomi SU7 Pro model, optional electric spoiler (tail wing), and four physical buttons on the center console to support the adjustment of electric spoiler (tail wing). This product adjustment can be cashed in the first delivery of Xiaomi SU7 Pro. At the same time, users who have made the SU7 Pro version of Xiaomi before April 30th will be given an electric spoiler (tail wing) for free, and four physical buttons will be provided at the time of delivery. Since the establishment of Xiaomi Company, we have been firmly making friends with users and adhering to the creed of "sense of participation". "Building a car behind closed doors" can’t create a perfect product that users are satisfied with. We look forward to your continuous advice and we will listen carefully.

2. Can you adjust the steering feedback of the steering wheel independently, or can you only follow the driving mode?

　　In "comfort", "sport" and "sport+",these fixed driving modes have factory preset steering feel and do not support independent adjustment; In the "M1" and "M2" custom driving mode menu, drivers can flexibly choose light, medium and heavy steering feel according to their own preferences.

3. Does Xiaomi SU7 have an in-car camera? Can it be turned off to protect privacy?

　　There is a camera between the steering wheel and the instrument panel to detect the driver’s state. When drivers are detected to be tired or distracted, such as closing their eyes, turning their heads, yawning, and using mobile phones to answer calls, the system will remind drivers to pay attention to safe driving through voice broadcast, central control screen pop-up window and other forms. The system only judges and reminds the behavior locally, and the image data will not be recorded or transmitted externally, thus fully protecting the privacy and safety of users. Of course, if you don’t need the driver fatigue/distraction reminder function, you can turn it off in the "Settings-Driving Preferences" menu of the central control panel. Even you can directly turn off the camera in the permission management of the car.

4. What is the specific function of the super power saving mode in the setting, and when will it be triggered?

　　Super power saving mode means that the vehicle can reduce the vehicle power consumption and increase more cruising range by turning off the intelligent driving assistance function, turning off or limiting the comfort functions such as air conditioning and seat heating, and limiting the maximum speed and vehicle acceleration performance. When the estimated cruising range of the vehicle is less than 50km, the pop-up window and explanation of relevant settings will pop up on the central control screen. At this time, you can choose whether to turn on the super power saving mode. At the same time, you can also actively turn on or off the super power saving mode at any time during driving. Please open the settings in the control bar below the central control panel, enter the driving preference > super power saving mode, and click to turn this function on or off. After the super power saving mode is turned on, the following vehicle functions will be restricted: the maximum speed limit is 90 km/h; The system sets a separate economic dynamic response to control a more gentle torque output; Limited air conditioning performance (reduced air volume and power); Turn off the steering wheel heating function; Turn off the comfort functions such as seat heating and seat ventilation; Turn off the ambient light; Turn off the outside rearview mirror heating and the rear windshield heating; Intelligent auxiliary driving function and intelligent auxiliary parking function are turned off; Turn off entertainment, ecological service functions, and turn off sentry mode; The vehicle-mounted 12V DC power take-off port is disconnected; Turn off the electric flow board (tail wing) control; Turn off the car smart refrigerator. When the vehicle starts the super power-saving mode through the pop-up window of the central control panel, it will automatically exit the super power-saving mode after the estimated charging mileage of the vehicle is more than 300km. After turning on the super power saving mode, you can still step on the accelerator pedal for a short time when overtaking in a short time.

5. What is the impact of Xiaomi SU7 standard tire pressure bar being lower or higher than the standard value?

　　Xiaomi SU7 comprehensively considered the needs of driving energy consumption, performance and other aspects, and formulated the design tire pressure of 2.9bar, and recommended users to adjust the tire pressure according to the cold inflation pressure of 2.9bar on a regular basis (for example, one month). Insufficient or excessive tire pressure will also have a certain impact on vehicle driving. For example, if the tire pressure is too high, it will reduce the rolling resistance of the tire and improve the bearing capacity and impact resistance of the tire; In addition, it will also lead to the overall hardening of the tire and a stronger sense of road when driving. On the contrary, if the tire pressure is too low, the rolling resistance of the tire will increase, and the bearing capacity and impact resistance of the tire will weaken; At the same time, it will make the whole tire soft and make the whole vehicle ride more comfortable.

6. There is no physical connection between Xiaomi SU7 brake pedal and caliper piston. What is the reason for this design and what are its advantages?

　　Xiaomi SU7 is equipped with the fully decoupled braking system of DPB+ESP10.0, which was launched by Bosch in the world. It has the following four advantages: Compared with the traditional mechanical vacuum braking system, the fully decoupled braking system of DPB can achieve faster pressure building speed, effectively shorten the braking distance, and help Xiaomi SU7 Max version to brake 33.3m at 100km/h-0.

　　The design of DPB and ESP dual-pressure-building modules can be mutually redundant. Combined with kinetic energy recovery, the function of quadruple braking redundancy can be realized, and the risk of brake failure can be eliminated to the maximum extent, which can meet the safety redundancy of L4-level automatic driving and lay the foundation for the upgrade of the assisted driving system in the future. Under extreme working conditions (such as emergency braking) of DPB fully decoupled braking system, there will be no pedal feedback fluctuation caused by ABS operation or brake master cylinder pressure fluctuation, which can provide drivers with stronger braking confidence and ensure safety. DPB fully decoupled braking system can combine motor kinetic energy recovery and mechanical hydraulic braking more effectively. Even if kinetic energy recovery is turned off in daily driving, when the driver steps on the brake pedal, the vehicle still uses kinetic energy recovery first to slow down, which can effectively improve the cruising range of the vehicle.

7. Can you give it to the vehicle with complete confidence in the process of automatic parking, and the driver doesn’t pay attention at all?

　　At present, intelligent driving is all assisted driving. When using the functions of intelligent parking assisted APA and parking service assisted AVP, the driver still needs to observe the surrounding environment and take over at any time in case of special circumstances.

8. Can I set the speed limit for automatic parking and AVP parking service?

　　At present, it is not supported to set the upper speed limit of intelligent parking auxiliary APA and parking service auxiliary AVP.

9. Is there any way for emergency machinery to open the trunk inside?

　　In case of emergency, you can open the trunk mechanically from the inside, as follows: fold the back of the rear seat and enter the trunk; Remove the decorative cover of the trunk emergency switch; Turn the trunk emergency switch counterclockwise and push it outward to open the trunk.

10. If the unlocking function of the charging gun fails, how to unplug the cable urgently?

　　If the user’s charging gun has an unlocking fault, you can use the emergency unlocking cable to unlock it. The operation is as follows: First, click "Stop Charging" in the car, and then open the trunk; Use a suitable tool (by hand) to remove the trunk maintenance cover and find the unlock cable switch; Pull the emergency unlocking cable of the charging gun towards the front of the car to unlock the charging gun and take it out normally.

　　"Today, my heart suddenly beats faster.

　　It is easy to get flustered when you move. "

　　"My heart is beating a little fast. Do you want to go to the hospital?"

　　… …

　　Recently, various statements circulated on the Internet.

　　Arouse a new round of worries of "Yangkang people"

　　The topic of "Beware of viral myocarditis after yang"

　　Once rushed to the top of the hot search list.

　　Jin Dongyan, a virologist and professor at the School of Biomedicine, Li Ka-shing Medical College of the University of Hong Kong, told the reporter that acute myocarditis really needs attention among the complications of COVID-19.

　　What disease is myocarditis?

　　According to Beijing Daily, myocarditis is an inflammatory lesion of myocardium, which can be caused by infection (such as viruses, bacteria or fungi) or non-infection factors (such as autoimmune diseases), among which various viruses causing intestinal and upper respiratory tract infections are the most common.

　　Clinically, myocarditis is mostly caused by virus infection, and the common cold can also be induced.

　　Myocarditis can launch an "indiscriminate attack" on people of all ages and sexes, but young people aged 20-40 are more likely to be recruited than the elderly and children.

　　After the virus enters the blood, it reaches the heart with the blood circulation. If the patient’s resistance is weak, it may cause myocarditis. Viral myocarditis refers to acute or chronic inflammatory pathological changes caused by viral infection, which belongs to infectious myocardial diseases.

　　Viral myocarditis has the following manifestations according to the severity:

　　Early myocarditis: manifested as fatigue, chest tightness, shortness of breath, palpitation, dizziness, loss of appetite, nausea, vomiting, dyspnea, chest pain, etc.

　　Mild viral myocarditis: symptoms such as arrhythmia, tachycardia or bradycardia appear, and myocardial ischemic changes can generally be found by ECG;

　　Severe viral myocarditis: the condition is dangerous, and the mortality rate is extremely high, which can reach 70%~80%, and death or sudden death occurs within hours or days.

　　Is the heartbeat accelerated after "yang" because of myocarditis?

　　Why do many people’s hearts beat faster after "yang"? There are eight possibilities:

　　1. fever

　　Every time the body temperature rises by one degree, the heart rate increases about 10 times/minute. If accompanied by symptoms such as chills and shivering, the heart rate may increase even more. After the body temperature drops, the heart rate will slowly return to normal.

　　2. All kinds of drugs taken

　　Some of the drugs used to relieve symptoms may cause the heart rate to increase. For example, caffeine and aminophylline in cough medicine, antiasthmatic medicine, some drugs inhaled by atomization, etc. These drugs can relieve symptoms, but they can’t kill the virus. Therefore, you should take medicine when there are obvious symptoms, otherwise taking medicine will not help much.

　　3. Physical reaction of hypovolemia

　　After infection, due to insufficient food, diarrhea, vomiting, infection or gastrointestinal reaction caused by drugs, it may lead to a certain degree of hypovolemia, and the heart rate will be compensated and increased.

　　Therefore, during the period of infection, we should appropriately increase drinking water, eat less and eat more meals, and even drink oral rehydration salts. Be alert to dehydration and seek medical advice in case of thirst and oliguria.

　　4. All kinds of pain may also cause the heart rate to increase.

　　Many people have experienced various pains after being infected with COVID-19, such as "craniotomy above, leg sawing below, waist cutting behind, laparotomy in front, and throat cutting with a knife", which is enough to stimulate the heart rate to increase.

　　5. Body’s stress response to virus infection

　　After being infected with the virus, the human immune system is activated, and the immune activation itself may be accompanied by an increase in basal heart rate.

　　6. Severe hypoxia

　　This is a relatively serious cause of rapid heart rate increase, usually accompanied by shortness of breath, severe cough, lung image changes, etc., commonly known as severe infection. According to the national diagnosis and treatment standards, if the respiratory rate exceeds 30 beats/min and the blood oxygen saturation continues to be lower than 93%, you should be careful of severe infection.

　　7. Accelerated heart rate induced by aggravation of basic diseases.

　　For example, patients with basic chronic obstructive pulmonary disease (commonly known as emphysema) and patients with basic heart disease (especially chronic heart failure) should be paid attention to if there is sustained increase in heart rate in these patients. The more obvious the heart rate increases, the more dangerous the condition may be. You should go to the hospital for examination and evaluation as soon as possible.

　　8. Myocarditis

　　Like other viral infections, Omicron has a certain probability of inducing myocarditis after infection. However, myocarditis usually occurs in the late stage of virus infection or 1-2 weeks later, which is related to virus-related immune response. In addition to the increase of heart rate, ECG will change and myocardial markers will increase significantly.

　　What circumstances should be suspected of viral myocarditis?

　　Pan Hongying, director of the Infectious Diseases Department of Zhejiang Provincial People’s Hospital, said that the course of myocarditis may last for hours to months, and serious complications such as cardiac arrest caused by dilated cardiomyopathy or heart failure.

　　If you have discomfort such as palpitation, chest tightness and shortness of breath, you need to be vigilant. It is recommended to seek medical advice in time, have an electrocardiogram and blood test. Generally, young people who love to stay up late are more likely to get fulminant myocarditis. If not found early, it will easily lead to cardiac arrest and multiple organ failure. It is suggested to rest, sleep more and not do strenuous activities within two weeks after infection.

　　Zhang Lei, deputy director of the Respiratory Department of Shanghai Children’s Medical Center affiliated to Shanghai Jiaotong University School of Medicine, said that it is necessary for the recovered people in COVID-19 to rest in 1-2 weeks. Zhang Lei said that after Covid-19’s infection, human immune function will appear obvious disorder, that is, the number and function of lymphocytes will decrease in the acute stage of infection, and then slowly return to normal with the recovery of the disease. Most people will have this "immune disorder period" lasting for 1-2 weeks. During the period, other viruses, bacteria, etc. are very easy to take advantage of.

　　If you are isolated at home alone, it is best to keep in touch with friends and relatives around you at any time, so as to avoid discomfort and go to the hospital in time.

　　Can you get myocarditis immediately after Yangkang?

　　According to the Life Times, the online saying that "it is easy to get myocarditis after recovering from yang kang" is actually exaggerated.

　　Even if you suffer from myocarditis after "Yangkang", the more direct reason is that Covid-19 has invaded the myocardium, and exercise is a fuse. In other words, the virus can only cause myocarditis if it invades the myocardium.

　　Li Dong, the chief physician of the Department of Infectious Diseases of Beijing You ‘an Hospital, once said that after COVID-19 recovered, it would take a week or two for many people to return to their previous physical condition, and it was suggested not to take strenuous exercise in the early stage of recovery.

　　Xinhua News Agency, Beijing, December 2nd Question: How to prevent and treat children’s respiratory diseases? How to combine traditional Chinese and western medicine? — — National Health Commission press conference responds to the focus of prevention and treatment of respiratory diseases in winter.

　　Xinhua News Agency reporters Xu Penghang and Li Heng

　　Recently, the flu has entered the high season. How to prevent respiratory diseases in daily life? How to treat children with respiratory diseases? How does the combination of traditional Chinese and western medicine play a role in treatment? The National Health and Wellness Commission held a press conference on December 2 to respond to the focus of prevention and treatment of respiratory diseases in winter.

　　No new infectious diseases caused by new viruses or bacteria were found.

　　Mi Feng, spokesperson of the National Health and Wellness Commission and deputy director of the Propaganda Department, said that at present, the National Health and Wellness Commission, state administration of traditional chinese medicine and the National Bureau for Disease Control and Prevention continue to carry out monitoring and judgment of respiratory diseases in winter, and make arrangements for adjusting medical resources, optimizing medical treatment procedures and giving full play to the role of traditional Chinese medicine.

　　Mi Feng said that according to the monitoring, all the current acute respiratory diseases are caused by known pathogens, and all of them have corresponding mature treatment methods, and no new infectious diseases caused by new viruses or bacteria have been found.

　　"We have been conducting mutation monitoring." Wang Dayan, director of the National Influenza Center of the Institute of Virology, China CDC, said that the monitoring results show that influenza viruses are sensitive to several current anti-influenza drugs, which means that anti-influenza drugs are effective against influenza viruses.

　　Vaccination against influenza can effectively reduce infection.

　　At present, the flu has entered the high season. Is it too late to get vaccinated now? Wang Dayan said that influenza vaccination is still effective for people who have not been vaccinated before, and it is recommended that you get the flu vaccine as soon as possible.

　　"Practice at home and abroad has proved that using vaccines is one of the most economical and effective preventive measures." Wang Dayan said that as long as it is vaccinated in professional institutions as required, it will have good results, especially for the elderly and children. They should actively vaccinate against influenza to ensure a normal pace of life and study.

　　Wang Dayan suggested that in daily life, we should wear masks scientifically, develop good personal hygiene habits, develop a healthy lifestyle, actively vaccinate and do a good job in self-health monitoring. If there are symptoms of respiratory infection such as fever, cough and sore throat, it is recommended to stay at home as much as possible and avoid going to crowded places. If you really need to travel, pay attention to wearing a mask to prevent the disease from spreading to others.

　　Give full play to the characteristics of traditional Chinese medicine and take many measures to strengthen the prevention and treatment of respiratory diseases in children

　　Recently, state administration of traditional chinese medicine issued the Notice on Further Strengthening the Construction of Pediatrics in Chinese Medicine Hospitals to promote the expansion and hierarchical development of pediatric medical resources in Chinese medicine as a whole.

　　Xing Chao, deputy director of the Department of Medical Administration of state administration of traditional chinese medicine, said that state administration of traditional chinese medicine is guiding Chinese medical institutions at all levels to strengthen resource coordination and strengthen the staffing of fever clinics, emergency departments, pediatrics and respiratory departments, and to meet children’s medical needs to the greatest extent by opening more clinics, extending outpatient hours, opening night clinics and weekend clinics, and providing "internet plus" diagnosis and treatment services.

　　Liu Qingquan, president of Beijing Hospital of Traditional Chinese Medicine, said that some Chinese medicine hospitals began to adjust the layout of pediatrics, increase the area of pediatrics and extend the duration of consultation. In view of children’s fever, cough, expectoration, diarrhea, etc., Chinese medicine hospitals at all levels have launched standardized and scientific videos through websites for parents and guardians to learn from.

　　Recently, in some places, the number of cases of children’s respiratory infection has increased significantly, and some children will develop bronchitis and pneumonia. In this regard, Wu Liqun, director of the Pediatrics Department of Oriental Hospital of Beijing University of Chinese Medicine, said that children’s acute respiratory infections belong to the category of colds, coughs and pneumonia. Chinese medicine believes that such diseases are caused by exogenous pathogens invading the human body, resulting in dysfunction of viscera and lung damage. Symptoms such as fever, stuffy nose, runny nose, sore throat, cough and expectoration occur.

　　Wu Liqun said that in the treatment of such diseases, Chinese medicine will differentiate syndromes and treat them accurately according to the different causes, symptoms and physical characteristics of children. For the early stage of respiratory tract infection, children mainly show symptoms such as fever, runny nose, sore throat and cough. The treatment methods of dispersing lung, relieving exterior syndrome and relieving sore throat are mainly adopted, and at the same time, according to the characteristics of children, the appropriate external treatment methods of traditional Chinese medicine are combined. In the recovery period of the disease, some children have symptoms such as cough, fatigue, poor appetite, etc. Traditional Chinese medicine adopts the treatment methods of invigorating spleen and resolving phlegm, tonifying deficiency and strengthening body resistance.
