Study of Energy-Saving Monitoring Network Node for Building Central Air-Conditioning Based on Zig Bee Technology

针对暖通空调耗能多、节能潜力大的现状,研发了一种基于Zig Bee技术的建筑中央空调节能监控网络,可实现对大型公共建筑或建筑群中央空调系统的实时监测与控制。网络节点根据IEEE 802.15.4/Zig Bee协议组成自组织无线传感网络,采用无线温度、湿度等传感器,对建筑环境温度、湿度,动力中心板式换热器二次侧供水、回水温度等参数进行实时采集。通过GPRS网络将现场运行参数传至监控中心上位机,实现了上位机对整个系统运行的节能管理与优化控制。

In view of the reality that heating ventilation air conditioning consumes much energy and has big potential for energy saving,a energy-saving monitoring network of building central air conditioning based on ZigBee technology was developed,which can implement real-time monitoring and controlling of large public buildings central air conditioning system.Based on the protocol of IEEE 802.15.4 /ZigBee,wireless sensor network can be self-organizing formed.Using wireless temperature and humidity sensor,the parameters of building environment temperature,humidity as well as the power center plate heat exchanger secondary side supplying and returning water temperature can be real-timely collected.The monitoring center upper computer receives the data from the operation parameters through GPRS network,realizing the energy-saving management and optimal control of the whole system operation.
