基于声表面波和ZigBee的高压开关柜电缆室温度监测
|
摘要
针对高压开关柜电缆室空间狭小,电磁干扰复杂的应用环境以及传统温度监测系统的弊端,提出了一种基于无源无线声表面波(SAW)传感技术与ZigBee协议组网的温度监测系统方案。结合热传导、热膨胀以及固体力学理论运用COMSOL软件对电缆室进行有限元分析,获得了温度分布以及热应变情况,为监测位置选定提供了依据;该系统采用声表面温度传感器代替传统的温度传感器提取温度信息,能够实现电气隔离;采用星型拓扑结构构建ZigBee无线网络实现温度数据收发,可以灵活配置。通过模拟实验平台搭建验证了该系统测温可行性。
Aiming at the application environment of narrow space of cable room in the high voltage switch cabinet,complex electromagnetic interference and shortcomings of traditional temperature monitoring system,a scheme oftemperature monitoring system based on passive wireless surface acoustic wave(SAW)sensor technology and Zig-Bee protocol is presented. Combining the theory of heat conduction and thermal expansion and solid mechanics,thefinite element analysis is carried out on the cable chamber by using COMSOL software,the temperature distributionand thermal strain condition are obtained,which provided the basis for the selection of monitoring position. Usingacoustic surface temperature sensor instead of traditional temperature sensor in this system can realize electrical iso-lation,using star topology structure to build ZigBee wireless network can flexibly configure. The feasibility of the sys-tem is verified by simulation experiment.
