Tang Lei, the cover character of "Science Chinese", is the director of the 771 Institute of the Ninth Academy of China Aerospace Science and Technology Group Co., Ltd
For the past two years, Tang Lei, as the director of the 771 Institute of the Ninth Academy of China Aerospace Science and Technology Group Co., Ltd. (hereinafter referred to as the "771 Institute"), has mixed feelings in his heart. He was once busy, anxious, nervous, excited, and finally his pride exploded, and he lamented that "these two years have seemed to have passed for many years", and even if he looks back today, his heart is still not calm for a long time.
Since the new crown pneumonia epidemic swept through the country at the beginning of 2020, he devoted himself to organizing the work of epidemic prevention and anti-epidemic, and after the domestic epidemic stabilized, he was busy directing the deployment of resumption of work and production. After the second half of the year, the epidemic spread to the whole world and intensified. At a time when the countries of the world are in chaos and panic to fight the epidemic, Chinese astronauts have suddenly sprung up and completed several eye-catching feats in succession!
The "Beidou-3" global satellite navigation system was successfully opened, the "Tianwen-1" deep space probe was successfully launched, the "Chang'e-5" probe lunar exploration mission was successful, and the space station core module "Tianhe" was launched into orbit... Among these major events, which one is a milestone event in the history of China and even the world's aerospace industry, and this series of aerospace feats is inseparable from the escort of 771 high-end advanced technologies and products, and it is also inscribed with the indelible key contributions of more than 7,000 "771 people" who have the ambition to serve the country.
The sea of stars is born from dreams. After 56 years of ups and downs, several generations of continuous struggle, 771 institute has always adhered to the revitalization of the national microelectronics and computer core basic industries as its own responsibility, becoming the only national set of computers, microelectronics and hybrid integration of the three major professional technology as one of the large-scale professional research institute, engaged in aerospace embedded computers, semiconductor integrated circuits and hybrid integrated circuit research and development, mass production support, testing and operation, is China's aerospace microelectronics and computers pioneer and main force. It has made important contributions to the rise and take-off of China's aerospace industry. Especially in recent years, with excellent ability guarantee and perfect modern management system, 771 has gradually built itself into an independent, innovative and reliable aerospace brand, and has written a number of national key projects and zero error achievements in flight tests with quality!
In 2019, Tang Lei, who has worked at the 771 Institute for 25 years, took over the baton of passing on the torch and became the new director. In his view, what the predecessors have passed on from generation to generation is not only the accumulation of scientific research, but also the feeling of serving the country in space and the belief in national defense! "'Strengthening the army with basic electronics and serving the country with the aerospace industry' is our constant sacred mission!" Tang Lei firmly said, "Do not forget the original intention, keep in mind the mission, our young generation will continue to forge ahead towards the grand goal of the world-class electronic technology institute, and make new contributions to China's aerospace industry and the modernization of national defense equipment." ”

Ambition is more outside of deep space
"Great careers begin with dreams, based on innovation, and become practical"
Aerospace has always been a national innovation weapon, and it is also a strategic commanding height related to national security and the sustainable development of the Chinese nation. Therefore, space technology has also become an important indicator of a country's scientific and technological level and comprehensive national strength.
Not long ago, as China's current space system project with the highest task complexity and the largest technical span, the "Chang'e-5" mission achieved China's first lunar surface sampling and encapsulation, lunar surface take-off, lunar orbit rendezvous and docking, carrying samples re-entry and return and other major breakthroughs, and its successful implementation marked the completion of the three-step plan of China's lunar exploration project "around, falling and returning" as scheduled.
As an important participating unit, 771 institutes have fully participated in the entire process of the lunar exploration project "around, falling, and returning", and in the process of "Chang'e Running to the Moon", we have seen a lot of attractive cutting-edge technologies, which are inseparable from the contribution of 771 institutes. Starting from the "Chang'e-1" in 2002, the 771 Institute applied the space effect key protection technology to computer products for the first time, enabling the digital tube computer products to successfully complete the flight mission in the deep space exploration space environment. In the second phase of the lunar exploration, the 771 Institute undertook the development task of the core control computer on the lander, and in 2013, the computer completed the landing, separation, mutual shooting and other target tasks as planned with the "Chang'e-3", making outstanding contributions to the end of the lunar exploration phase II mission. In 2018, the computer products of 771 institutes achieved the first human lunar landing with "Chang'e 4", and at the same time, 771 institutes developed satellites such as satellite center computers, solid-state memory and imaging observation camera controllers for Chang'e relay satellites (Queqiao).
As the core of the sampling and return mission of China's lunar exploration phase III project, the "Chang'e-5" probe is the most complex spacecraft system that can stand shoulder to shoulder with the manned space station, consisting of 4 parts of the orbiter, the returner, the lander, the ascent device and 15 subsystems. The 771 is equipped with a CPU module for the ascender and returner integrated management unit. The CPU module adopts standardized and modular design, and the dual-machine cold backup. As the core component of the integrated management unit, the CPU module is known as the "brain" of the integrated management unit, which is the control source of the ascender and the returner, mainly responsible for the measurement and control transponder to receive and execute all the remote control direct instructions sent by the ground, complete the collection of telemetry data and the distribution of remote control indirect instructions, as well as the heating loop control drive, provide the star reference time, collect various types of telemetry data group frame downlink and other functions, responsible for controlling each subsystem, making it operate normally.
Tang Lei said that the characteristics of deep space exploration missions, including lunar exploration projects, are long flight distances, prolonged communication time, and harsh space environment, which puts forward higher requirements for the light miniaturization, reliability, and autonomous management capabilities of digital tube computers. Over the years, through continuous exploration and optimization, 771 institute has broken through the design technology of miniaturization and standard modules, which has greatly improved the function/volume ratio of the product, created a precedent for miniaturization of digital tube computers, and broken through the complex coding technology of telemetry data to ensure the reliable transmission of star and ground data. In the recent mission, the computer products of "Chang'e-5" have adopted key technologies such as redundant backup technology, autonomous cutting machine technology, and miniaturization design technology, which not only helps the probe achieve the mission goals of China's first automatic sample return of the lunar surface and carry out lunar sample ground analysis and research, but also brings back the first lunar soil collected by the Chinese for researchers.
China has become the third country in the world to master lunar sampling technology after the United States and the Soviet Union, which undoubtedly marks that China's aerospace technology has steadily ranked first in the world. Tang Lei proudly introduced that the sample encapsulator used by Chang'e 5 for preserving lunar soil is the SiP computer LSCCU01RH of the 771 Institute, which is a highly integrated, highly reliable and miniaturized product for space applications. The LSCCU01RH module, the central control unit SiP computer, is a typical product of the 771 Aerospace SiP platform. This information processing microsystem module takes the 771 anti-irradiation SoC as the core, expands the memory and bus drivers, and realizes the common interface of the spaceborne computer. Its principle framework comes from the summary of the experience of the development of 771 spaceborne computer models for many years, and adopts a new generation of micro-assembly technology in the process realization, realizes the deviceization of computer single-board products, and meets the design requirements of light and miniaturized spaceborne computers.
Undertaking the launch tasks of Chang'e-5 and the space station is the Long March 5 carrier rocket. It is a new generation of non-toxic, non-polluting large-scale carrier rockets in China, which is the main rocket and key model in China's future, with a carrying capacity of 25 tons in low Earth orbit. But such a behemoth, but to accurately send the payload to hundreds of kilometers away in space, how to ensure the precise control of the rocket? Tang Lei gave the answer: this depends on the "brain" of the rocket - the arrow-mounted computer.
The arrow-mounted computer is a key guarantee for rocket control and accurate orbiting. The "Long March 5" can fly stably, which is inseparable from the arrow-mounted computer developed by 771. It can methodically complete a number of complex control tasks such as arrow body parameter admission, flight trajectory error correction, and control command output to ensure the stable flight of the rocket. The arrow-mounted computer adopts multi-processor parallel execution and control cycle synchronization technology, and 7 central processing units complete a number of complex control tasks such as arrow body parameter admission, flight trajectory calculation, flight trajectory GPS error correction, and control command output under the synchronous pulse control of three out of two votes. 18 two-way high-speed data exchange channels are designed between the 7 central processing units to complete the data flow transmission control between the processing units inside the arrow machine. The central processing unit is like the neurons in the "brain", and the high-speed data exchange channel is like the neural network in the "brain", which combines the independent central processing units into an organically combined whole to jointly complete the flight control task of the arrow-mounted computer.
The "Long March 5" rocket and arrow on-board computer is also designed with a unique "stethoscope" that can automatically "monitor" various important parameters during the operation of the flight control software, and automatically frame these parameters to the ground measurement and control system for storage without the participation of the software. This set of "auscultation" devices, Tang Lei called "bus monitoring technology". This technology enables the control system to obtain more raw data of the execution process without modifying the flight program control process, timely and effectively discover the hidden dangers in the system, and provide a basis for the fault location of the system.
Tang Lei said that bus monitoring and Jiandi high-speed serial communication technology have realized the comprehensive down-transmission monitoring of carrier rocket dynamic data for the first time. But the development process of this innovative technology is a difficult "hard bone" from beginning to end! Tang Lei recalled that from the beginning, the project team consulted a large number of literature, consulted experts, repeatedly modified the design scheme of the arrow-borne flight control computer, and realized the autonomous collection and independent down transmission of dynamic parameters by embedding the data flow "eavesdropping" circuit and adding corresponding communication protocols. The "strict, cautious, meticulous and practical" work style of astronauts makes each of them silently stick to the laboratory to repeatedly check, make technical improvements many times, and constantly iterate. In the trial and testing stage, the team does not miss any slight anomaly, solves every tiny defect with a very low probability of error, and ensures the correctness and reliability of dynamic parameter transmission. This technological innovation makes it possible to fully obtain the dynamic parameters of the equipment on the arrow without modifying the rocket flight control software, and provide data criteria for the rocket launch decision, at present, the technology has become an important support technology for the launch decision of China's new generation of carrier rockets, including the "Long March 5".
The mechanism of full dedication, tolerance of failure, encouragement of everyone to do it with confidence, and bold thinking has inspired the scientific and technological workers of the 771 Institute to promote innovation and change step by step. Tang Lei frankly said that it is the bold attempts to deny and deny, subvert and subvert, so that they have obtained more technological updates and experience accumulation, so that this collective can grow and grow more rapidly.
Of course, in the process of development, it is inevitable to encounter many difficulties and problems that need to be solved urgently, and even emergencies. But the team members worked together to overcome difficulties and never gave up. Tang Lei recalled that when the first unmanned rendezvous and docking mission of China's manned space project entered the final stage, the "Tiangong-1" target vehicle was already in orbit, and the "Shenzhou-8" spacecraft was about to be launched. At this moment, the news came that the "Shenzhou 9" spacecraft, which had the same technical state as the "Shenzhou No. 8" spacecraft, had an abnormality in the thermal test of the whole ship, and the central computer had crashed when receiving a special command in a specific temperature segment. According to the convention, when this situation occurs, the launch work of "Shen VIII" should be terminated, and the launch should be reorganized after the "Shen JIU" problem is solved, but because the "Tiangong-1" is already in orbit, the "launch window" left for "Shen VIII" is very short. If the launch cannot be carried out on schedule, it will have to be postponed for at least a few months, which will affect the subsequent "Shenjiu" manned rendezvous and docking mission.
The time is pressing, and a key battle of "great coordination among the three places" has begun. The project team formed a technical research team headed by Tang Lei in Xi'an and began fault location and problem analysis overnight, leaving him and the team with only 72 hours! Analyze, verify, overturn judgments; re-analyze, re-verify, re-overturn judgments... After three consecutive days and three nights of review of the analysis process and various test data, Tang Lei and his team made the conclusion that "this anomaly only appears in a specific environment on the ground, and only when receiving specific instructions, and does not affect the 'Shen VIII' flight mission", and finally got the unanimous approval of more than 150 "video consultation" experts, and the engineering general command immediately decided that the "Shenzhou VIII" spacecraft was launched as scheduled as originally planned! At that moment, Tang Lei's tired face finally showed a long-lost smile. He summed it up in one sentence: "That's what we do – it's hard and hard, but we're happy and proud!" ”

"Thirty-nine firsts"
"No matter how far you go, don't forget the way you came"
To rejuvenate the country through science and technology, there is a long way to go. This road is full of thorns and full of games.
In October 1965, in order to complete the task of developing and guiding micro-digital computers for China's strategic intercontinental missiles, the scientific and technological elites of the six research institutes affiliated to the Chinese Academy of Sciences, shouldering the heavy trust of the motherland and the people, gathered in Zhongguancun, Beijing, and established the "156 Engineering Office of the Chinese Academy of Sciences", which is the predecessor of the 771 Institute of the Ninth Academy of China Aerospace Science and Technology Group Co., Ltd.
Looking back at the road in the past 56 years, several generations of 771 people have passed on the torch, closely linked their personal careers with the feelings of home and country, starting from a poor and white, blue wisps of the road, from scratch, from small to large, with sincerity and wisdom, diligence and sweat to write the 771 continuous development of the historical macro, behind this string of solid results, are a process of breaking the situation that is difficult to describe. The tenacity and tenacity of the wave sweeping through the waves, calmly coping, forging the general quality of 771 people's steel, and also subtly forming a cultural connotation of hard work, innovative development and people-oriented.
Strength is the best proof of development results. A number of "world records" and "national records" were born here. According to statistics, in the 56 years of consistent struggle, 771 institutes have successively won 117 national, provincial and ministerial honorary awards such as the National May Day Labor Award and the National Civilized Unit, of which 15 have won the special prize of the National Science and Technology Progress Award and the special prize of the National Defense Science and Technology Progress Award in the past 10 years. In particular, in the past 56 years since its establishment, "771 people" have always adhered to independent innovation, and strived forward on the road of localization, production and ensuring autonomy and controllability, creating 39 first achievements in the history of the development of China's microcomputers, semiconductor integrated circuits and hybrid integrated circuits.
At the end of 1969, 771 completed the relocation from Beijing to Lintong. Relocated from Beijing, the capital with relatively complete scientific research conditions, to Xi'an, although it has just arrived, but ambitious, shouldering a thousand heavy burdens, turning into a driving force for forging ahead, 771 people around the development of aerospace science and technology and the major strategic needs of the country, worked together, faced difficulties, designed and manufactured a variety of models of special computers, covering a variety of task types, with hard work and sweat to open up and consolidate this road of national defense science and technology innovation.
With the deepening of reform and opening up, 771 institutes have carried out activities of introduction, absorption and foreign exchanges, expanded to the main battlefield of the national economy, and broadened the road of economic development. Through the development of this period, the institute has formed a scientific research and production system from the system to the whole machine, the whole machine to the circuit, and the whole industry chain, and has become an important base for the aerospace basic electronics industry.
In 1993, 771 and 691 factories merged to form the new 771. Geographically, from Lintong to four districts and five places, the industrial chain has begun to take shape, completed the "secondary entrepreneurship" of re-casting brilliance, and successfully laid the status of the national team as a "big institute". The 771 institute has thus entered the fast lane of development.
It was during this period that Tang Lei entered the 771 Institute after graduating from Beijing University of Aeronautics and Astronautics and began to carry out research on related technologies. He calls himself the "Second Generation of Hang", his parents are the elders of the 771 institute, in his eyes, this is a heroic collective full of legends. Tang Lei recalled that when he first entered the institute, the conditions of the institute were still relatively difficult, but he saw that the older generation of scientific researchers still insisted on independent research and development even if the conditions were not perfect. They worked overtime, slept and forgot to eat, encountered difficulties, solved difficulties, failed, started from scratch, and had a very persistent spirit, which left an unforgettable impression on the young Tang Lei, and also made him firmly remember the qualities that a person of the 771 Institute should have.
Under the experience of this environment, the young Tang Lei grew up step by step and began to shoulder heavy responsibilities. As an expert in the field of aerospace embedded computers, he has long been engaged in the research of large-capacity data storage technology for aerospace. Tang Lei makes full use of the advantages of the combination of 771 embedded computer systems, microelectronics and hybrid integration, vigorously promotes the research of modular intelligent systems and intelligent microsystem technology, presides over the completion of a variety of embedded intelligent module products, and first applies them to China's new generation satellite platform represented by CAST4000, which promotes the upgrading of China's satellite electronic systems.
On-board data recording equipment is an important part of modern Earth observation satellites and military reconnaissance satellites, and is one of the key equipment for obtaining overseas reconnaissance data. Therefore, the spaceborne large-capacity solid-state data storage technology is also one of the key technologies that Western countries have tightly sealed against China. Over the past ten years, Tang Lei has presided over the research and development of five generations of large-capacity solid-state storage technology suitable for harsh spatial environments, and creatively proposed a centralized management and distributed processing architecture for on-board large-capacity data storage systems that meet both high-speed data storage and efficient retrieval of massive data. While breaking through key technologies, it has promoted engineering and pragmatism, established product series and type spectrum, and applied to 107 different types of satellites, which has greatly promoted the development of China's Earth observation satellite technology.
Tang Lei has maintained the records of the longest-serving team leader (12 years) and the youngest chief engineer (39 years old) in the history of 771 institutes. On the one hand down-to-earth, on the other hand looking up at the stars, the achievement of achievements is not achieved overnight, Tang Lei has poured a lot of effort into personal growth, team building and technical management, and the R& D team led by him has been engaged in the development of starship products for many years, exploring the development of a new generation of spaceborne computer technology, always adhering to refined management and continuously improving product quality. Within the 771 Institute, such a "consensus" has even been formed, as long as it is the task undertaken by the team led by Tang Lei, whether it is the development of the model task, or the daily management work such as quality review, everyone has a sense of reassurance, because this is a team with orderly management and good at fighting hard battles. All this is not caused by a momentary luck, but the result of strengthening the basic management of the team for a long time and continuously improving the quality awareness and responsibility awareness of the team members.
"Lunch Talk" with Frontline Employees
"Third Entrepreneurship"
"All starting points and footholds are to support the construction of the country's space power and meet the development needs of the people."
Since 2015, 771 has entered the third stage of development, which Tang Lei called "the third entrepreneurship". It was also in this year that he entered the management of the 771 Institute and began to serve as deputy director.
Tang Lei introduced that the most distinctive feature of this period is technological innovation, and the whole institute has made a number of major technological breakthroughs in various professional fields. Over the past few years, 771 institute has made full use of the unique advantages of combining the whole machine with the circuit, the combination of integrated circuits with mixed circuits, and the combination of design and process, and realized the transformation of core technology from tracking development to original innovation, the transformation of integration technology from plane integration to three-dimensional integration, the transformation of technological innovation from single discipline to multidisciplinary, the transformation of product form from stand-alone supporting to system integration, and the transformation of development mode from aerospace special to high-tech integration, and gradually formed the three major industries of computer, semiconductor integrated circuit and hybrid integrated circuit 3. A good pattern of scientific development.
In 2019, Tang Lei officially took over the baton of the director of 771 institutes. At that time, the situation at home and abroad was undergoing profound and complex changes, and the world was in the midst of unprecedented major changes, especially with the intensification of confrontation in the great power game, it was urgent to further accelerate the process of China's promotion of localization and substitution. With the burden on his shoulders, Tang Lei understands in his heart that in today's world, only innovators advance, only innovators are strong, and only innovators win! Therefore, he pays special attention to technological innovation, continuously increases investment in research and development, and on the new voyage of development of 771, he never forgets to shape the core competitiveness with scientific and technological innovation and occupies the commanding heights of industry development.
"The reason why 771 can become a famous institute is the result of the continuous struggle of generations of astronauts, and on this platform, many well-known people in the country and the industry have grown up." Tang Lei knows in his heart that in order to make the scientific research level of 771 institute stand proudly at the forefront of the world for a long time, talent is the first resource and a booster for the rapid development of enterprises. Therefore, since becoming the director, he has planned to build a four-tier pyramid-like talent echelon.
"In the spire part, we hope that during the '14th Five-Year Plan' period, a high-end doctoral team composed of 100 to 150 doctors will be formed, so that they can free their hands and feet and be responsible for cutting-edge technology research and development." Tang Lei introduced, "We have formulated several major directions represented by advanced microelectronics, high-performance processors, information processing microsystems, artificial intelligence, quantum computing, etc., and we will never allow others to card our necks in the future!" ”
Led 771 institutes to Xi'an Jiaotong University to learn the spirit of westward migration, and discussed school-enterprise cooperation with President Wang Shuguo (first from the right).
"The second echelon of the pyramid is a team of excellent masters with certain work experience, they aim at user needs and are responsible for developing new products that users need; the personnel of the third echelon upgrade and optimize our existing mature products according to the requirements of users; the fourth echelon is the maintenance personnel of our existing products, providing users with technical support and services, including the debugging of products in the production process." Tang Lei was drawing such a grand blueprint for the future from his hands. The establishment of the pyramid echelon enables every "771 people" who choose to struggle to find a position that matches his ability, thus maximizing his ability to help him tap his potential and play value.
Tang Lei believes that if you want to take the lead in this round of scientific and technological innovation, you must strengthen your own technical prediction, find the direction, and deploy in advance, especially in some basic, cutting-edge, exploratory, and subversive areas. Under his leadership, the institute aims to do a good job in the research and development and exploration of "frontier, exploration and subversion" technology of 771 institutes based on basic theories, and established an R&D innovation center, which also marks that the technology research and development work of 771 institutes has entered a new stage. The R&D innovation center is committed to the future technological upgrading and industrial development of 771 institutes, forging core competitiveness, and continuously promoting the modernization process of aerospace engineering and weapons and equipment. "The R&D innovation center adopts a new appraisal mechanism, and I give them great autonomy, including free working hours." Tang Lei has the courage to break the rules and regulations, giving the technological pioneers the space and freedom to think whimsically.
At the same time, as a top expert in the industry, Tang Lei himself has been thinking, in such a wave of development, how will embedded computers develop to play a good core role? As early as 2013, at a meeting of the Institute, he gave the following predictions: First, in the foreseeable future, the development of computer technology will still be based on silicon materials; second, quantum computing and neural computing will not enter large-scale applications at least in the next decade. Based on this premise, in the future, embedded computers will develop in the direction of smaller and smaller size and stronger functions under the impetus of Moore's Law and super-Moore's law, and embedded computers will be more and more deeply embedded in target applications. Tang Lei believes that the highest realm of embedded computer development is that we use it all the time, enjoy its services all the time, and do not feel that we are using it, do not notice its existence, just like the use of electricity. He firmly believes that microsystem technology will be an important means of the development of ultra-Moore's Law technology, and the system is small enough to appear unexpected application patterns, just like today's mobile phones.
Based on this forward-looking thinking, many years earlier than the same industry, Tang Lei presided over the demonstration and organized the construction of the first wafer-level TSV microsystem production line in China, which can realize the TSV process development of the largest wafer in the industry, the processing of wafer-level advanced packaging products, and integrate TSV stereoscopic integration, RDL rewiring, micro-bump preparation, FC upside down, and BGA packaging. On this basis, combined with the advantages of the integration and development of the three major industries of the 771 Institute, he creatively proposed the information processing microsystem solution, integrated various mature technologies and mature circuits at the micro-nano scale, and built a high-performance information processing system through system optimization design, which has the advantages of supporting multi-process and heterogeneous material mixing integration, short research and development cycle, low research and development cost, etc., to a certain extent, it gets rid of the constraints and imitation of semiconductor processes and device generation differences, and solves the problem of independent controllability and development efficiency of equipment. He has undertaken a number of major nuclear high-tech projects, among which relying on the "anti-irradiation microsystem integration module" project, he has successfully developed the first spaceborne situational awareness microsystem in China, integrating functions such as visible light image acquisition, information depth processing and microsystem management into the same package, achieving a hundredfold improvement in performance, volume and weight optimization, which is at the highest level in China.
Standing at the new starting point of the "third entrepreneurship", the leadership team led by Tang Lei implemented the strategic layout adjustment from "four districts and five places" to "one body and two wings", and put forward the strategic goal of "three steps" from 2021 to 2045, that is, by 2025, it has the conditions to launch an impact on the construction of a world-class electronic technology strong institute; by 2035, it will basically build a world-class electronic technology institute and become the leading force to ensure the national basic electronic security and provide world-class aerospace electronic products and services By 2045, we will build a world-class electronic technology institute in an all-round way, form a brand with world influence, and effectively support the construction of world-class weapons and equipment.
"Success doesn't have to be in me, but success must have me!" In such a great era, we have witnessed and shared the well-being brought to mankind by the development of science and technology, and we will certainly create new brilliant achievements. Looking forward to the tide of the new era, the sea of stars, tomorrow can be expected, Tang Lei and all the "771 people" are full of ambitions for the future.
