Take root in Gobi, work hard and be a "devotee" of the space industry. Since 12, he has successively served as power system operator, power system commander, power system commander, team leader, deputy director and director. No matter what position, he always regards work as the main theme of his life, overcomes many difficulties in personal and family aspects, and writes a song of dedication with practical actions. After the Spring Festival in 2003, his mother was hospitalized for heart disease. In order not to affect his work, his family has never informed him of this situation. At the end of XX mission, my father suffered from prostate tumor and needed surgery urgently. The family wants him to go home and take care of him. Considering that the task entered a critical stage, he re-selected the task, and his father was very understanding and supportive, delaying the operation date. After the task was completed, he hurried home to visit his sick parents. On the third day after he got home, he received a phone call asking him to prepare for a business trip to Shanghai. He stayed at home for only a week and immediately left for Shanghai. During the XX mission, as the person in charge of the room and the force commander, I had no time to send my children to the hospital during the day and had to work overtime at night. During the child's hospitalization, he didn't look at it from beginning to end and devoted himself to the task. In September, 2005, my mother's right leg was swollen. As soon as her foot touched the ground, it hurt terribly and she couldn't walk alone. She was hospitalized again. At that time, the Shenzhou VI mission was the most tense. As the first person in charge of the launch vehicle testing room, he resolutely buried his family affairs in his heart and devoted himself to the mission.
Be rigorous and realistic, strictly control the quality, and be a "paver" on the road to flying. Success and failure are only one step away, and carelessness is always a taboo in scientific research and experiment. His earnest, meticulous, rigorous and realistic work style and meticulous work attitude are well known. During the first general inspection data interpretation of XX mission, he found that the accumulator pressure value was 0.002MPa lower than that of the system test. The comrades of the test team thought it was caused by temperature, but he insisted that it was caused by battery leakage. The test proved that his judgment was accurate. In order to find out the mechanism of the problem, he led his men to calculate and compare, and found that the test method of accumulator had serious defects. He put forward a new idea of accumulator pressure monitoring, which was adopted by the experimental group, and added an accumulator monitor in the follow-up task. During the test of initiating explosive device in Shenzhou 5 mission, he carefully observed the fragments of initiating explosive device with a magnifying glass, and found that the thickness of the pole pin of the explosive bolt separating the ship from the arrow was uneven. After computer camera analysis, the difference in the thickness of the polar needle is only 0.05mm, which was also keenly captured by him, and the test team called him "critical". On the day before the control and maintenance of Shenzhou VI mission matched with the interface of the spacecraft, the matching program and the state check matrix were determined, and the commander of the control and maintenance system confirmed that the state was correct. In order to ensure that the state is absolutely correct, he carefully analyzed the detailed rules, procedures and circuit principles, and came to the conclusion that when X 1GC is not connected, the secondary equivalence of the control system should not receive the escape signal. The prosecution system organized the in-depth analysis of the first and second post personnel, which confirmed his judgment and avoided a major mistake. Because he can not only adhere to principles and strictly control quality on key issues, but also coordinate and handle relations in his usual work; Not only can it lead the organization to carry out its work and play the role of "system command", but it can also put forward its own unique opinions at various times and have a heart-to-heart talk with the cooperative units, which has won unanimous praise from the superior leaders and the experimental team. Everyone respects him as an "expert" in rocket test and launch.
A "leader" who carefully organizes and directs and does arduous and dangerous tasks. In the face of difficult and dangerous tasks, he never said a word "no" and always fought at the forefront. XX mission launch -90 minutes, the ground equipment of each rocket system began to power up. Suddenly, the control system VXI test program initialization error, the test can not continue. This is a failure mode that has never been encountered before, and there is no corresponding treatment method in the plan. If the problem is not solved soon, the emission process will be suspended. He decisively ordered the front and rear microcomputers and cabinets to be re-energized, and ordered the VXI host to re-bind the test program. As time passed, when the operator reported that the work was normal, everyone was very worried. According to the process, the control system was tested again and the task was launched on time at the designated window. When the Shenzhou VI mission completed the test work in the technical area, the B code ignition control terminal suddenly broke down, and the rocket test work has entered the countdown. He led the staff to race against time, cooperated with the designers to carry out experiments, ate lunch boxes on the ground for four consecutive days, and worked overtime until 4 am at night. In the case that the fault can't return to zero and the launch date is approaching, he boldly suggested giving up automatic ignition and adopting manual ignition. During the circuit resistance test of initiating explosive device before filling in Shenzhou VI mission, it was suddenly found that the pin on X2 14 test socket contracted at 1. The most direct consequence is that the circuit resistance of 1 point and 92 point cannot be tested. At the same time, when the short-circuit plug is plugged in, point 1 and point 2 are connected with point 92, which reduces the reliability of initiating explosive device to prevent accidental explosion. If the electric detonator explodes unexpectedly, it will lead to the accidental opening of the accelerant starting valve of the secondary engine. If this happens after the rocket is filled, the burning agent in the tank will flow out through the starting valve and pipeline, and the consequences will be unimaginable. After a day and a night's analysis, he put forward the solution of testing the loop with pin method and adding aluminum foil to the short-circuit plug, which was recognized by the mission headquarters. The diameter of the socket is less than 2 cm, but there are 92 core needles with a diameter of not less than 0.5 mm. Whether testing or adding aluminum foil is a very detailed and dangerous job. In order to ensure foolproof, he organized closely at the scene, handled the short-circuit plug 3 hours before shooting, and successfully completed the resistance test of the initiating explosive device circuit.
Unremitting pursuit, pioneering and innovating, and being a "pioneer" in testing and launching technology. The greatest enemy of learning is self-satisfaction. He regards learning as an important means to constantly enrich himself and improve himself. In September of 20001year, he was recommended to study for a master's degree at National University of Defense Technology as a double tutor. He seized this rare opportunity and settled down to study hard. During the one-year study, he not only completed the required courses, but also took several specialized courses related to his major and future work, and published many papers at the same time. The pursuer's footsteps will never have information. Based on the detailed analysis of the control system and the fault inspection system, the scientific research projects "CZ-2F Control System Simulation Training System" and "CZ-2F Fault Inspection System Simulation Training System" led by him adopt object-oriented technology to truly simulate the rocket test and launch process, which makes the on-the-job training of personnel more standardized and concrete. After expert evaluation, this achievement has reached the advanced level in the military, filling the gap that there is no training equipment in the shooting range between missions. Both projects made progress in military science and technology in 2003. In 2002, he participated in the scientific research project "Research and application of technical safety control measures for manned space test launch", standardized the technical safety order and control in the launch test, made clear the potential safety hazards in important control periods of each system, formulated corresponding control and disposal measures, ensured the safety of the test, made up the blank of quality control standards, and won 30% military prize. The multimedia demonstration system of CZ-2F rocket power system, which was built in 2003, used 3DMAX to model and assemble the components, and demonstrated the whole process of engine work and rocket flight. It has been applied to personnel training and achieved good results. The project won the first prize of excellent teaching materials for final assembly. In the CZ-2F rocket launching mission, due to the unknown interference in the loop, the accurate aiming information often cannot be transmitted smoothly. In order to get an accurate aiming information, it is often difficult, and sometimes the operator even risks to return to the aiming position and confirm it with the naked eye. In order to improve the reliability of the system, he led the staff to deeply analyze the working principle of the aiming system and put forward a plan to develop the rocket aiming information acquisition system. In this system, CCD imaging devices are installed behind the eyepieces of the main and auxiliary photoelectric theodolite, and the eyepieces are output to the information acquisition, processing and display system, and then transmitted to the back end through the cable TV system. The rocket fine aiming results are clearly displayed to commanders at all levels. Before shooting 15 minutes after the aiming personnel are evacuated, the operators of the launch console and the superiors can make decisions according to the corresponding information, which improves the reliability of the aiming system and realizes the visualization of aiming information for the first time in the domestic aerospace field.
Strictly control the training of talents and be a "willing person" in the construction of technical room. As the director of the technical laboratory, he has always been committed to improving the comprehensive experimental ability, strengthening the overall construction of the laboratory, paying close attention to the standardized management of experimental tasks, personnel training and scientific research project development, and the overall construction of the laboratory has been steadily improved. He pays attention to the overall development of the room and personal long-term development, grasps individual dynamic elements, optimizes internal functions, and cultivates compound talents such as general manager and conductor. In view of the ideological concerns of comrades who are afraid of taking responsibility and risks, we should strengthen cross-post training for personnel, so that their subordinates can learn the detection principles and corresponding operation procedures of other related posts on the premise of mastering the detection principles and corresponding operations of this post skillfully, and enhance the understanding and cooperation between systems. At the same time, through the way of handing in tasks and pressing the burden, let the general post operators participate in the compilation of proofreading procedures, plans, principle books and teaching materials, and strengthen the familiarity and professional and technical level of the operators. At the beginning of 2005, he used the test database, schematic diagram, fault auxiliary map and simulation training system to strengthen the training of "one expert with many functions" and "strict quality control". According to the characteristics of the mission, the organizer compiled the Code of Conduct for Operation in Rocket Cabin and the Post Responsibilities for Rocket Test and Launch, which provided a guarantee for standardizing the test operation and eliminating errors. In order to solve the current situation that personnel are unfamiliar with plug operation and prone to operational errors, he led the personnel to make 90 kinds of 128 plugs commonly used in rockets into a simulation training platform, developed a highly simulated plug insertion training device, and organized the operators to practice for hundreds of times. In the "one ship, three satellites" mission test, there has not been a misoperation.
