Failure logic modeling method for a high-speed railway train operation control on-board system
First Claim
1. A failure logic modeling method for a high-speed railway train operation control on-board system comprising modules and components, the method comprising steps of:
- determining the functional relationship between the modules and components of the train control on-board system;
analyzing the modules and components to identify failures and failure modes based in part on results of the determining step and on known failures of the train control on-board system accessed from a database;
generating an FMEA table to associate, for each module and component for which a failure was identified, at least one of the failure modes; and
modeling and simulating the failures using a modeling tool.

Abstract
The present invention provides a failure logic modeling method for a high-speed railway train operation control on-board system, including the following steps: determining the functional relationship between the structure and the parts of the train control on-board system; analyzing the failures of the parts based on known failures of the train control on-board system in combination with brainstorming; establishing an FMEA table to generalize the failures of the parts; editing and simulating the failures by using a modeling tool. By adopting the present invention, the failure modes analyzed are more systematic, and the failure logic modeling can be carried out from a global perspective more easily, the whole process can be better targeted meanwhile, the security analysis complexity of the train control system will be effectively reduced and the development period of the train control system will be shortened.
