[0002] With the rapid development of the urban rail transit industry, the manufacturing level and technological capabilities in the rail transit field have also been significantly improved, and the number of vehicles and the technical content have been significantly improved. However, rail transit vehicles will inevitably fail during actual operation, especially with the gradual increase in new subway lines. Once a rail transit vehicle fails, it will affect the comfort of passengers. In severe cases, it will affect the performance of the vehicle and cause immeasurable economic losses. Therefore, it is particularly important to carry out effective inspection and maintenance of rail transit vehicles.
