A device for measuring building energy using Local Information Module

摘要

The present invention relates to a building energy measuring device using a local information module, the measuring device includes a plurality of local information module (Local Information Module) attached to each field device of the building to collect operation data from each field device; An information controller which receives operation data collected by each local information module and controls each field device according to the received operation data; And a central monitoring system that monitors the status of each site device in the building by communicating with the information controller, wherein the information controller communicates with the central monitoring system through the Ethernet communication network, and communicates with the local information module through the backnet MS / TP protocol. Local information module, the power supply; A signal input unit for receiving operation data, which is information on an operation state of each field device, during operation of each field device as an analog signal or a digital signal; A signal converter for converting an analog signal into a digital signal among operation data; A data storage unit for storing operation data; A wireless communication unit for wirelessly transmitting operation data to the information controller; A wired communication unit for transmitting operation data to an information controller or a central monitoring system by wire using a backnet MS / TP protocol; A central processing unit calculating operation data stored in the data storage unit and controlling transmission to the wireless communication unit and the wired communication unit; And an LCD display unit for displaying the start state, stop state, operation data, and abnormality of each field device.
