In response to the problems of low training efficiency, weak practical abilities, and scarce training resources among urban rail transit vehicle maintenance workers, the integrated training system for urban rail transit vehicle maintenance offers different training platforms according to the training needs of various maintenance personnel in urban rail transit vehicles. These platforms include a whole-vehicle training platform, an electrical fault diagnosis training platform, a train control system training platform, and a traction system training platform. The system supports both single-system independent teaching and training and multi-system joint training, meeting the training requirements for theoretical learning, equipment recognition, repair process practice, and fault diagnosis of the entire urban rail transit vehicle system.
