"Big data" of Xiaoxin
Xi'an, CCTV, Dec. 6 (reporter Liu Tao, correspondent Zhou Yanzhen) "by downloading and analyzing air conditioning data, we can find or prevent the causes of poor heating effect of air conditioning in advance..." At the pre shift meeting held by the data diagnosis group of Xicheng operation workshop of Xi'an EMU section of China Railway Xi'an Bureau Group Co., Ltd., in view of the characteristics of air conditioning equipment on Xicheng high-speed railway in winter, Xin Huabin proposed his own countermeasures. A 6031 a 6031 Xin Huabin inspects the bogie status of EMUs (Photo by Wang Shutian, CCTV) a 6031 a 6031 29 year old Xin Huabin is a technical full-time in Xi'an EMU Xicheng operation workshop. Although Xin Huabin is not old, he is a "technical big shot" in this workshop. The analysis of "big data" is the key to Xin Huabin's daily diagnosis of EMUs A magic weapon. A 6031 a 6031 in November 2017, Xi'an Chengdu high speed railway is about to open, Xi'an motor car section is newly equipped with crh3a EMU, the whole body of the model has about 500 sensors, which provides great convenience for real-time data monitoring of the state of the train. Xin Huabin, who has many years of data diagnosis experience, is arranged to lead the way to carry out the technical preparation of the new model. As the first high-speed railway line across Qinling Mountains in China, Xicheng high-speed railway is particularly demanding for the performance of EMU, especially the 45 km long 25 ‰ continuous long ramp between Yiyi and Xinchang street, which has unprecedented test for EMU traction and brake belt. New lines, new cars, new problems, for a while, many complex problems that have never been touched before have been placed in front of Xin Huabin and his colleagues, which has become a "stumbling block" for the normal maintenance of the workshop. Seeing that the date of the opening of the new line is getting closer and closer, some technical blind areas have not been solved yet. Xin Huabin is anxious in his eyes. During the period of
, Xin Huabin led the team members to eat and live in the unit. During the day, they will lead them to conduct real-time monitoring on the parameters of the key parts of the moving train set when they go online every day, conduct remote fault alarm on the EMU running on the line, check the cause of the fault in advance, download the existing vehicle data at night, find out the hidden danger points, and formulate the fault handling process. Before the new line was opened, a EMU suddenly reported that the front windshield was fogged. The operators tried all the disposal operations and they did not solve them. Xin Huabin and his team are urgently involved in tackling key problems, turning over the manual, checking the circuit, testing simulation, and operating comparison After several twists and turns, Xin Huabin finally found clues in the EMU CCU data, and solved the problem thoroughly. In this way, Xin Huabin led the data diagnosis team to make full use of the technical advantages of CRH3 EMU Operation data real-time transmission, one by one pulled out the "roadblocks" hindering the smooth opening of xi'an-chengdu high speed railway, successfully completed the preparation work of crh3a EMU before it was put into operation, effectively ensuring the smooth opening and operation of xi'an-chengdu high speed railway. In the past two years since the opening of the
Xicheng high speed railway, Xin Huabin and his team have monitored more than 10000 EMUs and downloaded tens of millions of on-board data. Through the selection and analysis of these "big data", 20 typical problem handling manuals have been completed and 13 key points for the maintenance of operating models of Xicheng high speed railway have been sorted out, which greatly improves the efficiency of EMU Operation and maintenance It ensures the safe operation of EMUs.
