Gao Shibin is checking the experimental data. Wang Yongzhan, Zhao Na, photo reporter's name card, Gao Shibin: born in 1964 in Suizhou, Hubei Province, professor of the School of Electrical Engineering, Southwest Jiaotong University. He is committed to innovative research and talent training in the field of railway power supply and automation, and has made important contributions to the construction and operation of China's electrified railway. The project of "Complete Set of Technologies and Equipment for Safety Assurance of High speed Railway Bow and Net System Operation", which he presided over and completed, has built a complete safety assurance system for high-speed railway bow and net system operation for the first time in the world, greatly improving the safety operation and operation and maintenance management level of high-speed railway in China. The scientific research projects he presided over or participated in won the second prize of the National Science and Technology Progress Award for four times, and won the 14th Guanghua Engineering Science and Technology Award in 2022. A cup of tea, a computer, and a stack of technical materials in hand. In the office of the School of Electrical Engineering of Southwest Jiaotong University, Gao Shibin stared at the data on the screen and thought deeply... He entered the office at 8:00 every morning. When he did not have classes, Gao Shibin would also make full arrangements for his work. "In the morning, we will mainly see the progress of our new research project, and then we will meet with team members to discuss," Gao Shibin said. For more than 30 years, he has studied railway power supply and automation, and now he is nearly sixty years old. Speaking of the growth along the way, Gao Shibin's thoughts returned to his youth... "Many old professors' spirit of seeking truth and being pragmatic and brave in innovation has had a profound impact on me." Gao Shibin grew up in the Mangmang Mountain and never left the county town until he went to high school. Get on the bus and walk along the mountain road for more than 70 kilometers. You can only get to the county seat after a day of wandering. "First, it's hard to walk, and second, it's expensive." Once he gets to school, he rarely goes home. Building roads was a dream of his youth. My father is a rural agricultural technician. Whenever there is a need to prevent diseases and insect pests during the busy farming season, the villagers invite my father home to help prepare pesticides. This also conveyed a belief to Gao Shibin: "Knowledge can make life better." In 1981, Gao Shibin was admitted to Southwest Jiaotong University. Faced with the fact that China's railways were still dominated by steam locomotives at that time, Gao Shibin put his professional choice on railway electrification. "Until 1988, when I graduated as a graduate student, China's electrified railway was only 4600 kilometers long, and the analog protection and control system was used. At that time, the railway speed was very slow and the failure rate was very high," Gao Shibin said. "Many old professors are pragmatic and innovative, which has a profound impact on me." Gao Shibin said that when he first went to college, he learned that Southwest Jiaotong University had opened the first railway electrification major in China in 1952, which was deeply impressed by the proposer, Professor Cao Jianyou. "After the founding of the People's Republic of China, Professor Cao resolutely returned to China, not only contributing to the education of railway electrification, but also helping solve many technical problems in railway construction." Gao Shibin said, "His patriotism has always inspired me." "It's like building a hospital for the high-speed railway bow network system. If there is a problem, you can immediately detect and repair it." Gao Shibin graduated in 1988 and stayed in school to teach. As soon as he was ready to apply what he learned to his work, he met the first
