[the second anniversary of the opening of xi'an-chengdu high speed railway] O Xudong: leading geese in fault diagnosis of "layman" in train maintenance

"Data shows that the EMU is in braking operation at the time of failure..." said Yang Rui, Wang Shutian, a correspondent with Liu Tao in Xi'an, CCTV In the office of "Dolphin data diagnosis group", a high-quality brand in Xi'an EMU of China Railway Xi'an Bureau Group Co., Ltd., O Xudong and Li Linjie, a worker, are lying in front of the computer, searching for "clues" of EMU fault handling from a line of dense data codes.

this is a snapshot of O Xudong's daily work. He and his colleagues are mainly responsible for typical troubleshooting and technical research of crh380b EMU allocated to Xi'an EMU, monitoring and analyzing the onboard data and remote data of EMU, finding the hidden problems of EMU in advance, and taking preventive measures.

time goes back to 2017. In the early stage of the opening of xi'an-chengdu high-speed railway, O Xudong, who had excellent performance in various work, was selected to the data diagnosis group, mainly responsible for the technical preparation and daily troubleshooting of crh3a EMU, the new model of xi'an-chengdu high-speed railway. On December 6, 2017, the xi'an-chengdu high speed railway was officially opened to traffic, bringing many new problems to the new line and new tasks. Then, the Spring Festival of 2018 came, and a large number of new models were put into operation. Some problems began to appear under the heavy load operation of the fleet. There was no experience for reference, no expert guidance, and the work difficulty was conceivable. A 6031 a 6031 a working day, the ground service inspectors found that the parked EMU reported "braking does not release", and this EMU will take on the operation routing in the early morning of the next day, O Xudong and the workers did not dare to delay for a moment, but could not care about the cold, ran all the way to the EMU storage line 3 kilometers away under the cold wind, got into the car, rubbed the frozen hands, and then stood up with the workers After downloading the data and carrying out the research and processing, it was early the next morning after the processing. At the moment when the EMU started, O Xudong was relieved. On the way back, O Xudong got drunk. He was so tired that he nearly fell down several times when he walked on the road for more than ten hours. Kung Fu is not inferior to those who want to. With his hard work, he and his workmates successfully completed the task of the Spring Festival. A 6031 a 6031 "during the period when xi'an-chengdu high speed railway was just opened, we had to add passengers for every bullet train to avoid problems". During that period, O Xudong and his colleagues took the initiative to give up their vacation, follow the train in turn, and cooperate with the on-board machinist to deal with the faults. In addition, there was no failure to stop and delay. In the later work, he led the data diagnosis team to conduct repeated observation and test in combination with Tiancheng, constantly summarized the failure rules, explored the failure solutions, and actively connected with suppliers to solve the problems. All problems were solved with the unremitting efforts of him and the team. Since the second anniversary of the opening of the

Xicheng high speed railway, O Xudong and colleagues from the data diagnosis team have solved 16 problems and completed the formulation of 20 motor car disposal manuals. During this period, O Xudong also grew from an ordinary worker to the foreman of the data diagnosis group. The team he led has won the advanced team of safety production for many times, and he has also won the honorary title of advanced individual of production. In the past two years, the xi'an-chengdu high-speed railway has witnessed o Xudong grow from a "layman" in motor train maintenance to a "leading goose" in fault diagnosis. The future of him and xi'an-chengdu high-speed rail is just like the name of O Xudong, Xuri Dongsheng, which is just at the beginning and will be bright.
