The state information includes the operation state information, the fatigue degree information, and the fault information. The fatigue information is compared with the pre-stored initial state information to estimate the estimated failure time. Cycle mileage information, cycle time information, analysis results and estimated failure time are comprehensively considered to determine to enter the first-level repair, second-level repair, third-level repair, fourth-level repair or fifth-level repair. The invention provides a five-level inspection and maintenance classification method for rolling stock according to the characteristics of the city railway, which ensures the safety and economy ofeach part.
