Design of Heartbeat Invalidation Detecting Mechanism in Triple Module Redundant Multi-Machine System

With turbine triple module redundant emergent trip system as research object of reliability and multi-machine system, a heartbeat monitor mechanism in high-reliability multi-machine system is introduced. The mechanism combines PUSH model with PULL model. Hierarchy heartbeat monitor and integrating the heartbeat message into data transmission are designed in the mechanism. The invalidation detecting mechanism combines PUSH with PULL heartbeat monitor model can enhance reliability and decrease the system misdiagnosis rate greatly. By adapting hierarchy heartbeat mechanism and integrating the heartbeat detecting message into the data transmission, the system communication cost is decreased. Simulation results prove the effectiveness and reliability of this mechanism.
