Background
The secondary monitoring system mainly realizes the functions of real-time monitoring, comprehensive alarming, risk early warning and global comprehensive analysis of the secondary system through the functions of unified modeling, data acquisition and exchange, real-time data processing and the like of secondary equipment. The server of the secondary monitoring system is deployed in a safety II area of a main station, and the acquisition end is deployed in a safety I area and is used for converging the running state information of various secondary devices in the safety area and acquiring real-time data such as remote measurement, remote communication and the like from the main station of a secondary professional subsystem (such as automation, information protection, safety control, network security and the like) through a message/service bus.
