Field problem rapid analysis method and device applied to rail transit

The invention provides a field problem rapid analysis method and device applied to rail transit, and belongs to the field of rail transit control, and the method comprises the steps: monitoring a fault code sent by a subsystem in a signal system according to a preset time interval; in response to the received current fault code sent by one or more subsystems in the signal system, intercepting a problem log corresponding to the current fault code from a preset path; writing the current fault code and the intercepted problem log into a fault storage area of a problem analysis system; and querying a fault analysis area of the problem analysis system, and outputting a corresponding analysis conclusion according to a query result. In this way, the current fault occurrence log can be autonomously positioned, a preliminary analysis conclusion is obtained, the difficulty that personnel repeatedly reproduce problem scenes is reduced, and the debugging time is shortened. 本公开提供了一种应用于轨道交通的现场问题快速分析方法和装置，属于轨道交通控制领域，其中方法包括：
