FACILITIES MONITORING SYSTEM AND COMMUNICATION METHOD FOR FACILITIES MONITORING SYSTEM

摘要

An object of the present invention is to provide a facility monitoring system using a BACnet-based facility monitoring system, in which a redundant structure can be adopted for a controller connected to a device in the facility. A monitoring system in which at least two controllers including a monitoring device and a first controller (11) and a second controller (12) are connected to each other via BACnet, the first controller (11) and the second controller (12) ), one operates as a controller of the operating system and the other operates as a controller of the standby system, a common virtual IP address is assigned to the first controller 11 and the second controller 12, and the first controller 11 And, among the second controllers 12 , a controller operating as a controller of the operating system communicates with the monitoring device 2 using a virtual IP address.
