As night fell, inside a new type of radar shelter, Jing Ke, a radar technician and third level sergeant of a certain brigade of the Air Force Radar Corps, led his comrades to urgently repair the radar. They had to troubleshoot the equipment before starting up for duty. When encountering such a fault, the first thing to do is to understand how the signal is formed and how the current is transmitted, in order to quickly locate the fault point Jingke held the testing instrument and explained the maintenance steps to his comrades while operating it. Jingke is a technical backbone in the field of radar maintenance and support for the entire tourism industry. He is proficient in various types of radar maintenance techniques, and when encountering "difficult and miscellaneous problems" with equipment, he often identifies the fault point and promptly eliminates it. Jingke is good at learning new knowledge and is also full of exploratory spirit. Every time the unit installs new equipment, he takes the lead and stands at the forefront. Jingke said, "Changing equipment is like changing a person's brain. Mastering the maintenance skills of a new type of equipment is like a 'breakthrough'. That year, the brigade was mobilized to the plateau for adaptive training when a new type of radar suddenly malfunctioned. Testing signals, inspecting circuits, debugging equipment... Jingke carefully investigated but could not find the "crux". Compared with old equipment, new equipment has a higher degree of informatization, more complex basic principles, and greater difficulty in maintenance. Seeing the passage of time in seconds, Jingke was so anxious that his forehead was sweating. Later, with the guidance and help of the manufacturer's technical personnel, he found the fault point and urgently eliminated it, ensuring the smooth progress of the training task. The difference between new and old equipment is significant, and past experience is no longer useful This experience left Jingke feeling disappointed. During the use of new equipment, new maintenance difficulties are often encountered, which is a necessary process for human equipment to adapt. I believe that as long as you calm down and focus on research, you will definitely overcome the difficulties. "The leader's words made Jingke secretly determined:" You must learn and understand the maintenance technology of new equipment, comprehensively improve the support ability of new equipment. "During that time, Jingke carefully studied the user manual and circuit principle diagram of new equipment, and combined with practical operation to understand the structure and working principle of components. He also sorted out difficult problems and consulted experts from manufacturers and universities one by one. A knife grinds on a stone, a person practices on things. Through diligent study and research, Jingke's maintenance and support capabilities have significantly improved, making it the first coach of this new equipment in the brigade and undertaking teaching and training tasks. Teaching is not just about understanding oneself, it's about making everyone understand Since becoming a coach, Jingke has continuously optimized its teaching mode and innovated its teaching methods. In class, he pays attention to using mind maps to organize the framework of knowledge, and uses forms such as "flipped classroom" to test the effectiveness of teaching; In practice, he led the participating officers and soldiers to study equipment components, carefully analyze the causes of faults, and propose solutions and prevention plans. In addition, Jingke also led the members of the brigade's equipment "research and development team" to write the "Radar Full Function Operation Manual" and "Fault Rapid Localization and Maintenance Manual" around the performance and typical fault elimination of this model of radar, helping comrades proficiently master the use and maintenance methods of new equipment. Directed training for Sergeant Zhang Jiahao, with active thinking and strong learning ability. Jingke tailored a study plan for him based on his professional expertise. Zhang Jiahao quickly grew into a professional backbone by studying professional theories and applying them in practice. During a major training mission, Zhang Jiahao flexibly handled various equipment failures to ensure the successful completion of the task and was awarded the third class merit. Keep moving forward, keep striving. Recently, Jingke has been participating in field mobile support missions with the team. While undertaking combat readiness duty tasks, he is closely monitoring how new equipment can perform best in unfamiliar and complex geographical environments, and has begun a new round of exploration.
