Abstract: Facing the sharply increasing pressure on maintenance and operation support of urban rail transit vehicle, to elevate vehicle maintenance efficiency and lower operation cost, centering on the functional characteristics of urban rail transit vehicle and the routine maintenance and operation process, the identification of data resources in the process of vehicle maintenance and operation is introduced, and the vehicle health management system development, intelligent wayside equipment installation and construction of maintenance operation information system are expounded. Therefore，the collection, application and collaboration of remote transmission data and wayside data are realized, the data value is fully brought into play, the vehicle status visual management, automatic information collection, automatic trigger of inspection operations are formed, and the data-driven maintenance and operation mode for urban rail transit vehicle is constructed.
