基于无线模式的中央空调节能监控网络应用研究

Application Study of Energy-Saving Monitor and Control Network for Central Air Conditioner Based on Wireless Mode

基于信息节能的理念,构建了一个基于无线模式的中央空调节能监控网络,实现了对大型公共建筑或建筑群中央空调系统的节能监测与控制。所研发的现场节能监控装置以PLC为核心,配以人机界面、GPRS模块等。过程控制系统采用以负荷预报为基准的节能监控策略。现场监控装置与系统监控中心采用GPRS无线模式进行组网与通信,通过GPRS无线网络,将设备运行数据上传给监控中心,监控管理中心可以对各节能监控节点进行远程监控管理。

Based on the idea of informational energy-saving, an energy-saving monitor and control rietwork of central air conditioner based on wireless mode is constituted, which realizes energy-saving monitoring and con- troll for central air conditioning system of large scale building or architecture complex. The core of onsite ener- gy-saving controller is PLC with man-machine interface and GPRS unit etc. Process control system uses energy- saving monitoring and control strategy based on load forecasting. GPRS wireless mode is adopted to implement the communication and networking between onsite controller and monitor center of the system. Through GPRS wireless network, equipment operating data are sent to the monitoring management center which conducts re- motely monitorin~ and controllin~ over every energv-~nvin~ nat]~_
