The message bus is a vital component of the basic platform in the centralized equipment monitoring and control system.It is an important support for the inter-process (between and within computers)information transmission,and mainly used for real-time data and events from telemetry and remote signaling.Inspired by the redundant network mecha-nism of switch HSR,in view of the network characteristics of centralized equipment monitoring and control system,this work studied the high availability mechanism for the message bus,and realized the dual-network and dual-cluster parallel redundancy and fault-tolerant high-reliability seamless switching technology of the message bus.The proposed method was indicated by experimental results to satisfy the stringent security,stability and reliability requirements of centralized e-quipment monitoring and control system,significantly improve availability and stability of the message bus and ensure se-curity and stability of the system without sacrificing performance.
