FAULT LOGIC MODELING METHOD FOR HIGH-SPEED RAILWAY TRAIN OPERATION CONTROL VEHICULAR SYSTEM

摘要

Disclosed is a fault logic modeling method for a high-speed railway train operation control vehicular system. The method comprises the following steps: determining a structure of a train control vehicular system and a functional relationship among parts; analyzing faults of the parts according to known train control vehicular system faults and the brainstorming; establishing an FMEA table to summarize the faults of the parts; and compiling and simulating the faults by using a modeling tool. The present invention makes a fault analysis mode more systematic, enables a global perspective to be taken more easily in the fault logic modeling, specifically and effectively reduces the complexity of the security analysis of a train control system, and shortens the development period of the train control system.
