"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.

　　Li Laijin is on his way to deliver takeout.

　　This summer, the number of takeaway orders in Beijing at night has increased by 60% compared with last year. According to data, Changping Huojiaying and Fengtai Minute Temple ranked first and second in the ranking of the most active business districts at night. In addition, in Yanqing District and Huairou District, the number of late-night barbecue orders increased by more than 4 times year-on-year. Behind the surge in the number of orders is every "on-time delivery" of the takeaway brothers. From 9:00 pm to 12:00 pm is the peak period of night takeaway orders. They shuttle through the streets and alleys, adding "dynamic beauty" to the night Beijing.

　　Delivery riders haunt at night "with additional subsidies and no one grabs orders"

　　"Ding Ding", at 10:59 pm, Li Laijin, who was born in 1996, received a new order.

　　From the "7-11" convenience store on Xierqi West Road to the "Contemporary City Home" community about 1.2 kilometers away, the system recommends that riders be delivered within 28 minutes.

　　"Hello sir, sorry for the long wait." After 20 minutes, Li Laijin completed the delivery, which was 8 minutes faster than the time suggested by the system. He just pressed the button to confirm "delivery completed", and the "ding ding" sounded, and the new order came again. Between 9:00 and 12:00 that night, Li Laijin sent out a total of 6 orders.

　　According to data from a takeaway platform, the number of late-night takeout riders born in the 1990s has increased by more than 60% compared with last year. Li Laijin is one of them. The site where Li Laijin works is located in Zhongguancun Software Park. During the day, orders are mostly concentrated in Internet companies, and most of the night orders come from residential areas near Huilongguan.

　　Gu Xiaofang, a 32-year-old female rider at the Wangjing shopping district, also likes to work at night. Gu Xiaofang’s site is divided into three groups. Her group has more than 30 people, and there are six or seven people who work night shifts every day.

　　"There are subsidies, there are few riders, and no one grabs orders at night." This is the main reason why Li Laijin and Gu Xiaofang like to work at night. According to Li Laijin, at the software park distribution station, the courier earns 10 yuan for delivering an order during the day, and there is a subsidy of 2 yuan for each order at night. At Wangjing Station, where Gu Xiaofang is located, in addition to the subsidy for each order, he can get an additional 20 yuan per night. In Gu Xiaofang’s view, the evening is the third time with higher income after the two dining peaks at noon and evening.

　　Mr. Jia, a 31-year-old father of two, runs more night shifts than other riders at the station. "If you run a dozen or so, you can earn 20 yuan more," Mr. Jia said. "I take the initiative to work the night shift until 12 o’clock every day."

　　According to reports, this year, Jia Shaoke has completed a total of 7,923 orders, with an average of 34 orders per day. The rider level has reached Gold 1, and the next promotion level is the most advanced king.

　　Order remarks are varied "Delivery of takeout and handwritten sweet words"

　　Many people like to write notes when ordering. Statistics from a takeaway platform show that from the beginning of 2019 to August 5, among late-night orders between 9 pm and 5 am, riders received more than 560,000 notes asking to buy cigarettes on their behalf. The request to throw garbage on their behalf ranked second, with 9,397; the third order note was somewhat unexpected, asking riders to "draw a picture". In addition, the number of messages asking riders to play games, dance, and tell jokes followed closely, with 4,595, 966, and 722, respectively.

　　Among the orders received by Li Laijin and Gu Xiaofang, buying cigarettes and snacks on behalf of others is the most common. Li Laijin said that he once visited five convenience stores to help customers buy "Yoyo Mei". He also added WeChat with customers to determine the brand type through video communication.

　　What impressed Li Laijin the most was that he once copied more than 100 words of "sweet words" for a customer and sent it with the takeaway. As for the customer’s note request, Gu Xiaofang said, "The company does not have a clear rule that must be met, but we can help with everything we can, and it is easy to do."

　　There is no shortcut to more work and more "I want to be the webmaster of the takeaway station in the future"

　　When it comes to the difficulty of delivering food, it has to be said that traveling in bad weather, about which the riders "love and hate".

　　Delivered in bad weather at night, an order can earn about 13 yuan, which is 30% higher than the usual day. And when it comes to windy and rainy weather, takeaway orders also increase.

　　Li Laijin recalled that there was a drizzle that night on August 20, and he delivered 11 orders within two and a half hours, nearly double the number of orders from the previous day.

　　After the early morning, the order interval was relatively long, and the riders began to gather together to chat. Whether the new number of kilometers ran broke the record, and whoever rose to a new high on the rider’s single king list could make them chat in full swing.

　　Due to the long-term exposure to the sun, Li Laijin’s skin was dark, in sharp contrast to his original skin tone. "The wind and the sun are a little old, but I’m still young." Li Laijin quipped.

　　Li Laijin became a delivery rider two years ago. In his opinion, this industry is more work and more money. You can earn as much money as you run as many orders, and there are no other shortcuts. "You can get as much as you do in this industry." He likes this. "As long as I have orders, I can work harder and harder, and I am not afraid to stay up late." Li Laijin said he will continue to work in this industry. "I want to be a delivery station manager in the future."

　　As soon as Li Laijin finished speaking, a "ding ding ding" prompted him: "You have a new takeaway order, please deal with it in time". Then, he quickly got on the electric car and drove into the night. Text/This reporter, Zhu Jianyong, trainee reporter, Han Qian, intern, Zhang Yujie, Zhu Yadi

　　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.

The "2024 China Beverage Industry Trends and Outlook" report released by Nielsen IQ shows that with the development of social economy, the beverage industry as a whole continues to lead the fast-moving consumer goods market. Entering 2024, the consumption scene, consumer demand, and sales channels of China’s beverage market are becoming increasingly diverse, and the future beverage market will also have the potential to "cycle through". At the same time, "quality-price ratio" replacing "cost performance" is becoming a new consumption concept recognized and pursued by a considerable number of consumers. Faced with such an obvious consumption trend, how can brands seize the opportunity and seize the market?

Under the trend of quality-to-price consumption, Big Kiln Beverages continues to gain the favor of the market and consumers by relying on an efficient and high-quality process that guides product design with demand insights.

The representative "big soda" product line of Dayao Drinks has three flavors: classic guest flavor, lychee flavor, and orange flavor. Recently, 520mL of pineapple flavor and PET series of lime flavor, pineapple flavor, and frozen pear flavor have been added, which are widely welcomed with outstanding taste. For example, Dayao frozen pear, the taste not only retains the freshness and sweetness of the frozen pear itself, but also combines the carbonated bubbles to make the taste more refreshing and rich. Return to Erbin’s Frozen, and continue to harvest a good mood.

In addition, in 2024, the big kiln beverage soda product will be upgraded to the juice version, integrating the original classic taste with the juice demand, and continuously upping the ante juice soda category on the basis of retaining the core characteristics of "refreshing atmosphere" to meet the diversified needs of consumers.

Product performance is outstanding, and quality requires strength to escort. Dayao Beverage has always attached great importance to product quality, and strictly checked from raw material procurement to production process. In terms of production, Dayao Beverage has opened up a full-link digital journey from channels, commodities, marketing, orders, payment to delivery with the help of digital technology, driving cost reduction and efficiency through digitalization. In March this year, Dayao Beverage organized various factories to hold a production mobilization meeting, and conducted a full range of process, operation, quality and other training for production front-line employees to improve the quality control awareness of operators, and ensure product quality while increasing production. Each factory carried out process standard implementation investigation and error prevention landing investigation, improved 41 control measures, strictly grasped the implementation of standards, and carefully guarded product quality.

While ensuring product quality, Dayao Beverage also reduces costs and increases efficiency, improving the competitiveness of enterprises. Since 2014, Dayao Beverage has continued to build production bases in Hohhot, Shenyang, Liaoning, Siping, Jilin, Shizuishan, Ningxia, Baoji, Shaanxi, Tai’an, Anhui, and Fuyang, covering North China, Northeast China, Northwest China, Central China, East China, and South China, narrowing the distance between the production end and the consumption end. Under the condition of ensuring product quality, it reduces transportation costs and channel distribution costs, and provides consumers with higher quality and cost-effective products, such as 520mL of large glass soda, which is comparable in price to about 330mL of conventional soda on the market. Many consumers say that Dayao soda is very enjoyable to drink when serving meals, and the price is also very reasonable.

In this way, Dayao Beverage adheres to market-oriented, consumer demand-oriented, steady innovation, and is committed to bringing consumers higher-quality products, leading the national soda into a new era of quality.

In recent years, Shandong Telecom has implemented the China Telecom Group’s "cloud transformation and digital transformation" strategy according to local conditions, firmly grasping the opportunity of digitalization, networking and intelligent integration development, empowering thousands of industries with digital transformation, and effectively promoting high-quality economic and social development.

Cloud computing bases deeply empower the digital economy

As a core resource in the digital age, computing power is the main productive force supporting the development of the digital economy. It is estimated that from 2016 to 2020, every 1 percentage point increase in the scale of computing power in our country will drive the growth of the digital economy by 0.4 percentage points and the GDP by 0.2 percentage points.

Railways or highways are the cornerstones of the power era, and cloud-network integration infrastructure is the foundation of the computing power era. "Cloud computing that provides computing power" and "network that provides connection and transmission capacity" are accelerating their integration, and computing-network integration has become an important direction for the development of computing power. On the one hand, in the digital economy era, computing power is required on a large scale, which is reflected in cloud computing at the infrastructure level; on the other hand, it is necessary to connect computing power in different locations through the network, and dynamically dispatch computing power to meet the needs of different groups of people and different enterprises. Therefore, in the computing power era, it is necessary to integrate cloud and network to form a foundation for promoting economic development.

China Telecom is providing rich computing power solutions, allowing large and medium-sized enterprises to enter the "computing power era" more and more deeply.

Smart classroom builds urban and rural teaching community

During the Warring States Period, the Jixia Academy, located in Linzi, the capital of Qi State (now Linzi District, Zibo, Shandong Province), became a major innovation in the history of Chinese education development. It was the earliest government-run institution of higher learning in the world, as well as the earliest Academy of Social Sciences and government think tanks in China. As the center of academic contention at that time, it contributed to the formation of academic contention.

Today, more than 2,000 years later, Zibo has once again witnessed the technological innovation in the history of education. In a rural middle school 25 kilometers away from Huantai County, Zibo, students can listen to the famous teachers of the county middle school through an interactive online teaching system. This "real person face-to-face" online teaching method is more realistic than traditional distance teaching. Various demonstration images and model props are more three-dimensional and fresh, bringing teachers and students a refreshing immersive classroom experience.

Under the guidance of the Zibo Education Bureau, Shandong Telecom has joined hands with Huashi Cloud Technology to jointly create an AI synchronous classroom teaching system, which has benefited 447 schools in Zibo. The first phase of the project covers 1720 classrooms through the 5G ?? education special network, and the online teaching client side covers 30,000 teachers, serving the teachers and students of primary and secondary schools in the city. 5G ?? VR classroom, which can realize the learning of science experiments and other courses, students can learn knowledge in the virtual reality world and enjoy an immersive learning experience; 5G ?? Remote live broadcast, breaking geographical restrictions and realizing the sharing of educational resources; 5G ?? MR multi-person collaborative teaching, achieving the learning effect across virtual and real space…

In response to the problems of uneven, insufficient and poor opening of courses in rural schools, Zibo uses this online smart classroom teaching system to carry out pairing assistance and personalized customization, promote the regular normalization of urban and rural network dual-teacher classrooms, and carry out curriculum research in urban and rural areas. Research on learning conditions, technology and curriculum integration and application research, urban and rural lecturers and teaching assistants work closely together to achieve the effect of 1 > 1 > 2, benefiting 200,000 teachers and students.

Connect upstream and downstream to promote industrial ecological prosperity

In the huge petrochemical plant area, there are many pipelines and towers. On the large screen of the intelligent monitoring center, you can see the green logo representing the safety status constantly appearing above the pipelines and towers. Infrared thermal imaging and gas detector split-screen can sense and monitor temperature exceeding standards and gas leakage… These scenes full of technology are launched after integrating a series of 5G-related vertical applications.

In the aspects of equipment monitoring, data collection, data transmission, and equipment inspection, oilfield refining and chemical enterprises have strict requirements for the use of wireless networks, which provides opportunities for new technologies such as 5G and visual recognition.

Sinopec Shengli Oilfield Branch and Shandong Telecom have established a comprehensive strategic partnership in the fields of smart oilfields, oil and gas production and industrial Internet information services, and jointly explore the deep integration of 5G communication, IPv6, industrial Internet of Things platform, cloud, big data, artificial intelligence, blockchain, data information services, data disaster recovery and disaster preparedness, cyber security and other technologies with the industry.

Shandong Telecom Dongying Branch and the second-level units of Shengli Oilfield have successively cooperated in the field of 5G customized network, jointly deployed 5G edge private network in Shengli Oilfield Luming Qingnan Oil and Gas Development Co., Ltd., realized the commercial landing of 5G super uplink service and edge UPF, promoted and implemented the 5G customized network of the adjacent mode, and created an integrated customized fusion service through the five-in-one customized network of "network edge cloud service" to achieve "cloud network integration, on-demand customization". The implementation of "5G Edge UPF" in the Luyuan Management Area of Shengli Oilfield Lusheng Oil and Gas Development Co., Ltd. helps to build a 5G smart oilfield management area, which can meet the personalized needs of the smart oilfield management area for high-resolution video return, massive machine communication and ultra-reliable low-latency communication. At the same time, combined with the application of new generation technologies such as artificial intelligence and big data, it presses the acceleration button for the construction of the smart management area of Shengli Oilfield.

The development of 5G custom network cannot be separated from the open cooperation of the industry ecology. Shandong Telecom takes the initiative to join the upstream and downstream industrial chain of the oilfield, and joins hands with Shengli Software, Yunke Hanwei, Shengli Haowei, Israel National Machinery, Israel Ruiying, Dadonglian and other enterprises to continue to play their own advantages, join hands with industrial partners and Shengli Oilfield to jointly innovate, and jointly promote the continuous maturity and improvement of 5G custom network related technologies and products.

Smart port, establishing a "China sample"

Rizhao, which has the reputation of "two ports connect the four seas, and the first line connects Asia and Europe", is the eastern bridgehead of the New Eurasian Continental Bridge Economic Corridor, the main node city of the New Eurasian Continental Bridge Economic Corridor, and the strategic fulcrum of the "Belt and Road Initiative" maritime cooperation. Rizhao Port’s throughput ranks sixth in the country’s coastal ports and is the ninth largest port in the world.

However, the container operation volume of Rizhao Port has grown rapidly, the risk factor of human operation in bad weather is high, and the port trucks work multiple shifts and labor costs are high. These pain points urgently need to accelerate the implementation of intelligent applications such as driverless driving. In order to help Rizhao Port break through the development bottleneck and build a fully automated container terminal, Shandong Telecom Rizhao Branch and Rizhao Port have formed a close cooperation relationship and continue to empower the 5G customized network driverless project.

The unmanned truck self-driving project gives full play to China Telecom’s strong cloud-network integration strength, and based on 5G technology, it has built the world’s first shoreside open fully automated container terminal, providing global ports with a "Chinese sample" of the transformation of traditional terminals into fully automated container terminals. It is of great demonstration significance for leading the construction of fully automated container terminals with "low cost, short cycle and fast effect".

The project has planned three business scenarios that fit the port business, including the remote control of port machinery, the remote driving of the truck, the precise positioning of the shore bridge and the container, and realized the precise driving route of the heavy truck (the wheel and the driving line maintain a distance of 20cm) and the precise parking and the precise positioning and transportation of the container by the crane, which greatly saved the cost of the terminal transformation. At the same time, due to the closed automated terminal design with controllable whole process, the stacking density is higher, and the land utilization rate of the port is higher. For the seventh time, Rizhao Port broke the record of the world’s first automated terminal loading and unloading efficiency maintained by itself.

The 5G "ultra-long-distance" remote intelligent driving technology in Rizhao Port has good handling and safety. It can return 7-way 1080p high-resolution video in real time, covering the driving perspective of the vehicle and the blind spot of the vehicle. It includes an automatic protection mechanism under abnormal network conditions, ensuring the safety of operations and making remote intelligent driving possible. This application accelerates the automation and intelligent process of Rizhao Port, improves the efficiency of terminal operations, and contributes telecommunications power to accelerate the construction of a world-class marine port.

As a national key basic network operator and the main force in the construction of digital China, Shandong Telecom will make full use of 5G, Internet of Things, artificial intelligence and other new generation Information Communication Technologies in the "computing power era", focusing on industry, education, medical care, energy, finance, government affairs, agriculture, small and medium-sized enterprises and other fields to strengthen scientific and technological empowerment support, and paint a brilliant picture of the development of digital economy in Qilu.

For Haval, the H6 product continued to sell well in China a few years ago, allowing consumers to buy a more cost-effective SUV. However, with the continuous promotion of new energy vehicles in recent years, all kinds of plug-in and hybrid vehicles are constantly updated, and consumers gradually raise their recognition of new energy vehicles. At present, Harvard’s new energy vehicles are not abundant. In order to maintain the previous sales, it is necessary to introduce more new energy vehicles to meet the needs of consumers. The recently unveiled Haval Xiaolong MAX is a brand-new compact plug-in SUV. This product has a brand-new upgrade in terms of shape design and power system, and it is also the first to take the new hybrid architecture of the Great Wall Hi4. So what is the strength of new car products? Can consumers recognize it? Let’s get to know each other.

Triple screen+skylight is standard in the whole system, which is larger than Song PLUS?

About Haval Xiaolong MAX, there have been a lot of appearance information maps exposed before, and I think everyone has a better understanding of this. Let’s talk briefly about the appearance here. As one of the latest new energy vehicles in the family, the front face of Haval Xiaolong MAX adopts a gradual mesh and a "boomerang" style headlight group. The logo of "PHEV" below can obviously make people recognize its identity. The side and tail designs are similar to those of traditional models, and the split taillights used by most models are also used. Generally speaking, although Xiaolong MAX is a brand-new new energy vehicle, its appearance can bring a certain freshness, but at the same time, it also retains some designs similar to Haval’s traditional models.

As an SUV model, what do you want to know most? Of course, in terms of size, Haval Xiaolong MAX locates a compact SUV. In terms of body size, its length, width and height are 4758/1895/1725mm, and its wheelbase is 2800mm, which is larger than its own Haval H6. In addition, we refer to BYD Song PLUS DM-i, which is also a compact SUV. Its length, width and height dimensions are 4705/1890/1680mm and its wheelbase is 2765mm respectively. Obviously, the size of Xiaolong MAX should be dominant in all aspects, even if it is placed in the same class, it will have a good performance. Because the side of the car body does not adopt the shape of the Haval beast or the Haval F series model, but adopts the D-pillar design with a larger inclination angle and a larger spoiler, it is expected that its internal seating space will be more spacious. In addition, Haval Xiaolong MAX not only has a large body size, but also has rich and flexible storage space, such as the upper and lower front door panels, the lower floor of the center console, the front and rear row of cup holders and a number of storage slots specially for mobile phones. Temporary small items can be stored almost everywhere, and the design is more intimate in terms of function and practicality.

The traditional dashboard plus central control has been difficult to attract consumers’ attention. In order to cater to the more scientific and comfortable interior trend style, Haval Xiaolong MAX adopts a triple screen design, with a 12.3-inch LCD central control screen+a 12.3-inch LCD driver’s screen+a 12.3-inch LCD instrument and HUD head-up digital display, which can make drivers more focused and greatly improve the entertainment function in the car. Moreover, you will find that among the models of this level, there are not many models with triple screens, which are generally used in models with a price of more than 200,000 yuan and 300,000 yuan. In addition, according to the previous application information, the skylight will also be standard in the whole department. It can be seen that Haval Xiaolong MAX is still sincere in the interior materials. Due to the design of the arms, it is more convenient for the center console to set aside more space to store items such as mobile phones. In addition, the rear seats can be laid down independently, which has good flatness, thus further expanding the storage space at the rear, which is very practical for some users to occasionally carry large items.

Pure electric battery life exceeds 100km, and the Great Wall new technology is equipped with two-wheel drive and four-wheel drive options?

In terms of power, according to the existing information, the new car is expected to adopt a plug-in hybrid system composed of 1.5L/1.5T engine and motor, which is matched with a multi-gear DHT gearbox. Among them, the entry-level model uses a 1.5-liter naturally aspirated engine with a maximum power of 85kW, while the middle and high-end models provide a 1.5-liter turbocharged engine with a maximum power of 113kW. As for batteries, lithium ternary battery and Ferrous lithium phosphate battery will be provided according to different configurations. It is expected that the version of lithium iron phosphate battery will further lower the price threshold.

According to the previous statement, the new car of Haval Xiaolong MAX will use the Hi4 hybrid system of Great Wall. Comparatively speaking, what is really worth looking forward to is this system, that is, the four-wheel drive function is realized through the structural cost of the two-wheel drive. So how does it achieve the four-wheel drive function? To put it simply, the Great Wall Hi4 is a two-axis and two-motor hybrid system. Under the original hybrid two-drive structure, a rear axle motor is added at P4 of the rear axle, which is equivalent to adding a drive system to provide power, thus realizing the function of four-wheel drive with the two-drive structure. In addition, the Hi4 hybrid special engine of Great Wall will have more than 40% engineering thermal efficiency, and the battery also has fast charging ability, which will be helpful for the improvement of battery life. The cruising range of pure electricity is expected to reach more than 100km. If you use pure electric mode for short-distance daily transportation, you basically don’t need to refuel frequently.

In general, Haval Xiaolong MAX has enriched consumers’ purchasing demand while providing various power versions. The most important thing is the blessing of the new technology of the Great Wall Hi4. This hybrid system will find the corresponding best working mode according to different scenarios used by users. For example, when the urban road conditions need to be accelerated or climbed rapidly, the vehicle will switch between pure electric four-wheel drive and one-speed direct drive mode according to the urban road conditions; Or when encountering high-speed cruise road conditions, the vehicle will adopt a higher 2-speed direct drive mode, which can effectively reduce the engine speed range and thus reduce the energy consumption of the system. In a word, the vehicle will intelligently switch different working conditions according to different scenarios, thus avoiding the high-energy consumption or low-efficiency operation interval.

Nowadays, new energy vehicles are becoming more and more common. Even without the inclination of the license policy, everyone is willing to choose it, especially plug-in hybrid vehicles. The main reason is that the plug-in and hybrid models can not only use pure electricity in cities, but also burn oil to solve the mileage anxiety caused by long-distance driving.

As a long-awaited plug-in hybrid model, the appearance of Haval Xiaolong MAX gives people a certain freshness different from family-style design, and the materials used in interior configuration are also kind enough, and it also uses its own Hi4 hybrid new technology in power, which is expected to help and improve power and battery life. If the pricing is reasonable, Harvard Xiaolong MAX is expected to attract a lot of consumers with these good products in the future.
