Title Design And Realization Of Remote Monitoring System For Air Conditioning Unit

Abstract In this paper, the remote monitoring and controlling system of central air conditioning system based on PLC and Force control is studied。 In the local end, the system uses PLC, 7188E5 and sensors to obtain the analog signals, transform them to digital signals, and transmit them to PC through virtual ports 。The remote controlling system is built based on the air conditioning unit,Panasonic PLC,7188E5,HUB and PC。SCADA( Supervisory Control and Data Acquisition) is used for PC configuration to monitor the parameters。The operating state of the air conditioning unit,the history trend and real trend chart are shown。Reportforms can be printed。 Then, data is released to the web through the web server of Force control。 In the remote end, connection is tested respectively based on local area network and wide area network。sonic PLC programming software, Force control and browser。 The way Using Ethernet is compared with the way using wide area network。 The connection scheme of software is given。 Both local automation and remote monitoring of the central air conditioning are successfully performed。
