A unified safety control method and system for the whole life cycle of a car stopping command facing multi-source conflicts across systems and manufacturers

Abstract

The application discloses a kind of cross-system cross-vendor multi-source conflict-oriented car stopping command full life cycle unified safety management and control method and system, the method includes steps: the original car stopping instruction from different signal systems is packaged as standardized safety car stopping event, synchronizes to global car stopping safety state synchronization unit, when multiple safety car stopping events for the same target and mutually conflicting occur, by the arbitration engine built in interlocking safety computer, based on the arbitration logic guided by fail-safe principle is arbitrated, to determine the only effective event;Each execution subsystem receives only effective event, by instruction adapter, it is converted into local instruction in line with the safety logic of this subsystem manufacturer and executed.Using the technical solution, through global car stopping safety state synchronization unit and the arbitration engine based on fail-safe principle, collaborative processing is carried out, and the collaborative processing and unified safety supervision of multi-vendor, multi-source, multi-level car stopping command are realized.
