摘要
近年来频发火烧山导致输电线路跳闸,对输电线路安全运行造成了很大的影响。针对输电线路长链状结构、山区公网信号覆盖不到位的情况,提出利用无线Mesh网络特性、采用嵌入式技术和长链状低功耗路由算法。根据山火特性,开发了以山火探测终端、中继器以及协调器组成的探测通信网络和基于B/S架构与GIS的专家监测软件构成的山火预警监视系统。经挂网运行数月后表明,该系统能准确探测和传输火灾信息,为输电线路山火预警提供了一种有效手段。
The forest fire resulting in transmission lines trip has taken place in recent years, and it has a great impact on the safe operation of transmission lines. According to the long chain structure of transmission line and the situation that network signal couldn＇t cover the mountain area, using the characteristics of wireless mesh networks, the embedded technology and the long chain structure of algorithm for low power, a fire early warning and monitor system is proposed based on the feature of forest fire. The communication network includes the terminal, router, centralized device. Besides, experts monitoring software is designed based on B/S architecture and GIS map. After the several months＇ operation, application result indicates the developed system can detect the fire with high accuracy and transmit the fire message, providing an effective method for the transmission line fires warning.
