为解决传统照明线路故障监测方法不能有效定位故障点的问题,研究基于物联网技术的高层建筑照明线路故障在线监测方法。通过小波分解,获得系数模极大值,将其与设定阈值比较,检测照明线路中的故障;保持相同的噪声赋值,经过小波变换得到独立分布,设定阈值去除噪声;通过ZigBee无线通信网络协调设备将故障点信息打包并传输至监控中心,发送下行指令传输给对应节点,完成故障信息传输,实现高层建筑照明线路故障在线监测。实验结果表明,运用本文方法对照明线路故障点定位监测精度较高,可实现对高层建筑照明线路故障的有效监测。

In order to solve the problem that the traditional lighting line fault monitoring method cannot effectively locate the fault point,an online monitoring method for lighting line fault in high-rise building based on the Internet of Things technology is studied.Through wavelet decomposition,the maximum of coefficient module are obtained and compared with the set threshold value,the fault in the lighting circuit is detected;It is necessary to maintain the same noise assignment,get independent distribution through wavelet transform,and set threshold to remove noise;The ZigBee wireless communication network coordination equipment will package the fault point information and transmit it to the monitoring center,send the downlink command to the corresponding node,complete the fault information transmission,and realize the online monitoring of high-rise building lighting line fault.The experimental results show that the method proposed in this paper has high accuracy in locating and monitoring the fault points of lighting lines,and can effectively monitor the faults of lighting lines in high-rise buildings.
