With the goal of quick response to fault handling, research on emergency handling methods for urban rail transit equipment failures. Based on the analysis of the current situation of emergency handling of urban rail transit equipment failures, a method for rapid response to equipment failure handling is proposed from the two dimensions of fault diagnosis and troubleshooting; Integrate decision tree and case-based reasoning methods to diagnose equipment faults, and use decision matrix analysis to make intelligent decisions on fault handling related resources. The research results of this paper provide a reference for emergency response methods of urban rail transit.
