From typical radar to general radar fault detection, from equipment electronic fault detection to all electronic equipment fault prediction, Cai Jinyan, a professor at the Ordnance Engineering Institute of the People's Liberation Army, achieved breakthroughs in major "bottleneck" problems that restricted the combat effectiveness of the army, effectively solving our military Due to the inconsistency of weapon equipment electronic system support standards and non-universal testing equipment, her achievements have won 1 second prize of the National Science and Technology Progress Award and 3 first prizes of the Army Scientific and Technological Progress Award. Multiple blanks. It was one day in the fall of 1992. When Cai Jinyan visited the army, he discovered that with the development of weapons and equipment and the continuous installation of new equipment, officers and soldiers could no longer detect increasingly complex electronic circuit failures with the original multimeters. Only wait for the manufacturer's technical personnel to complete the inspection and maintenance. As a science and technology worker, Cai Jinyan realized that future high-tech wars, not to mention a few hours, or even a few minutes, may affect the outcome of a war. If this happens on the battlefield, what price will we pay? Cai Jinyan was determined to develop an automatic detection device similar to a point-and-shoot camera, to make equipment fault detection simple, intelligent, scientific and accurate, so that army officers and soldiers can learn to use it. She first attacked the problem of typical radar fault diagnosis. The key to this project is to use VXI bus test technology to quickly collect fault information and determine the fault location after comprehensive analysis. At that time, this technology had just emerged internationally, and only one or two units in China were in the research stage. Cai Jinyan led the research team to learn the principles of technology, collected more than a thousand copies of relevant domestic and foreign materials, translated more than 800,000 words of foreign academic papers, used holidays to ask experts at Tsinghua University, wrote more than 500,000 program codes, designed Thousands of circuit drawings. On one occasion, in order to find out the trend caused by a certain component failure, Cai Jinyan stared at the computer screen continuously for days and nights like a demon. A hundred pieces of data came out without results. A thousand pieces of data and 10,000 pieces of data came out. There is still no rule to follow. Someone in the research group persuaded her: "When you do this, when will you be a leader? Give up." The expected signal has failed to be programmed many times, and the urgently needed data has been debugged repeatedly without results. Difficulties and failures made Cai Jinyan exhausted in his perseverance. At this moment, she would think of the eager eyes of the army officers and soldiers. After countless days and nights, Cai Jinyan and the members of the research team finally overcame all the difficulties and conquered the difficulties, and completed the "General Radar Equipment Support Project", "General Equipment Electronic System Comprehensive Detection Platform", and "Electronic Equipment Failure" Research on topics such as "prediction" has reduced the number of detected faults in the past from a large number of people to one person for a few hours, changing the situation that the support fleet is longer than the combat fleet during military exercises, which greatly improves our military equipment maintenance support capability and combat capability. . The road to exploration is endless. The “Reliability-based Electronic Equipment Failure Prediction Research†proposed by Cai Jinyan was evaluated by the National Natural Science Foundation of China as “Excellentâ€, which maximized the effectiveness of weapon equipment potential failure prediction and life-span management for equipment preventive maintenance and equipment preliminary Development provides a theoretical basis. The team brought by Cai Jinyan is mostly young people. Cai Jinyan said: "I grew up on the shoulders of the older generation of scientific researchers. Without them, I wouldn't have the achievements I have today. Paving stones. "So, she often publishes her opinions to the public, and gives the young people the application topic, so that the young people can take the lead. In 2008, the research team undertook the research and development of a certain type of equipment support equipment. She took the research team member Ma Yanheng to study the ideas and design plans together, and let him serve as the project leader and help him by himself. For the first time he was in charge of the project, Ma Yanheng was excited and nervous, and he felt lost. Cai Jinyan taught methods and rational ideas on how to deploy strength, grasp progress, and mobilize staff enthusiasm, and encouraged him to let go. In the face of technical difficulties, Cai Jinyan also worked with him to work overtime and gather intelligence to tackle problems. In the end, the project successfully completed the prototype development. When applying for the results, Ma Yanheng insisted on putting Cai Jinyan's name at the top, but she rejected it. She said: "As long as the students I cultivate are useful for army building, my value has been realized."
