摘　　要：为掌握建筑电气设备运行状态以及时发现并解决故障,设计了基于无线传感网络的建筑电气设备自动监测系统。利用系统数据层中无线传感网络的无线传感器节点采集建筑电气设备信号数据,使用中心节点汇聚并整合采集的数据,采用通信层的ZigBee无线网络将中心节点整合的数据汇聚到内部网关,通过该网关将数据上传到应用层的应用基础平台。应用层的建筑电气设备故障自动诊断模块根据接收的数据,运用基于压缩感知理论的建筑电气设备故障自动诊断方法,实现建筑电气设备自动监测。实验结果表明,将无线传感网络簇首数量设置为15,可以获得较理想的网络节点生命期;该系统在精准诊断故障类型的同时,还可以辨别故障位置,并能有效节省建筑电气设备能耗。In order to master the operation status of building electrical equipment and find and solve faults in time,an automatic monitoring system of building electrical equipment based on wireless sensor network was designed.Use the wireless sensor node of the wireless sensor network in the system data layer to collect the signal data of building electrical equipment,use the central node to gather and integrate the collected data,use the ZigBee wireless network in the communication layer to gather the data integrated by the central node to the internal gateway,and upload the data to the application basic platform of the application layer through the gateway.According to the received data,the automatic fault diagnosis module of building electrical equipment on the application floor uses the automatic fault diagnosis method of building electrical equipment based on compressed sensing theory,to realize the automatic monitoring of building electrical equipment.The experimental results showed that the ideal network node lifetime can be obtained by setting the number of cluster heads to 15;The system can not only accurately diagnose the fault type,but also identify the fault location,and can effectively save the energy consumption of building electrical equipment.
