[0002] With the acceleration of my country's urbanization process, urban rail transit has come into being. Urban rail transit refers to a fast passenger rail transit mode that connects the central urban area and satellite cities in economically developed and densely populated urban areas, with a large city in the region as the center. The distance is usually within 100 kilometers, and it adopts a "high-density, small-group, bus-like" transportation organization model. It is responsible for the short-distance passenger transportation mainly for commuter passenger flow in large cities.

[0003] With the continuous promotion of urban rail, the inspection and maintenance of urban vehicles are becoming more and more important. Urban vehicles use AC current and adopt a "high-density, small-scale, bus-like" transportation organization mode, so they are different from subways and high-speed railways.
