摘要
介绍了基于MSP430F149单片机和G18数据通讯模块的输电线路绝缘子污秽遥测系统的设计与实现。该系统通过数据监测分机实时在线检测输电线绝缘子表面的泄漏电流和环境温、湿度等数据,利用GSM网络以短消息(SMS)方式将数据传到远程系统主机进行分析,得出绝缘子的污秽状况,并在污秽过度时及时告警,为准确划分污区和实现状态检修提供了科学依据。
The design and realization of a kind of insulator contamination telemetry system for transmission line are introduced in this paper. This system measures the data of leakage current on surface of insulator, temperature and humidity of environment online through the data acquisition unit based on the theory of adaptive noise cancellation. The data is transmitted to remote supervision system by Short Message Service（SMS） based on GSM network, and analyzed by system software. When the contamination degree of insulator is serious, the system gives alarm signal in time. It provides scientific basis for plotting contamination zone correctly and realizing state examinination and repairment.
