"Local experts" conquer high technology
News from this newspaper (correspondent Dong Zhiguo, Qin Guozhong) recently, Jiang Xuefeng, a technician in the electronic group of the equipment workshop of Mudanjiang locomotive depot, reported to Zhu Yujie, the director of the workshop, "the Qitaihe crossing alarm experiment was successful." There is a special railway line in Qitaihe workshop yard of
section. The special railway crossing is the only way for workers to go to work. There are many cars and pedestrians passing through the crossing every day. Because the crossing is unattended, personal safety hazards often occur. In order to prevent personal safety and road injury accidents, it is a good way to install crossing alarm.
in order to solve the potential safety hazard as soon as possible, the general Party branch of this equipment workshop decided to research and develop the crossing alarm as the public relations topic of the third quarter of the general Party branch. At the Party branch meeting, Jiang Xuefeng, a technician in the electronic group, stood up and proposed to develop it by himself. Yu Panli, the foreman, expressed his full support and cooperation. The
crossing alarm is a high-tech equipment with complex technology, without any reference. Jiang Xuefeng went to the library to search for relevant materials, while learning the core technology of crossing alarm - sensor on the Internet. Because the special track sensor needs to be programmed and installed outdoors, it is necessary to not only prevent lightning, but also consider the running speed of the locomotive. These let Jiang Xuefeng eat for more than a month, sleep bad, sometimes a dream inspiration, wake up immediately put into research. In addition to searching for information on the Internet, she also communicated and consulted with experts of the manufacturer, consulted the technical parameters of the sensor, and finally understood all the programming links. It was designed as 6-17 hours light plus language alarm, night light flashing alarm. After repeated installation and debugging by the foreman Yu Panli and other technicians, it worked well and was put into use successfully.
