电线故障会引起火灾,对电线温度、电流进行在线监测能预防事故发生。设计了采用自供电无线传感网络的电线安全监测系统,系统由传感节点、中继节点、路由节点、服务器和客户端组成。采用自供电技术解决无线传感网络监测系统中传感节点不能持续供能的问题,对传感节点工作状态进行控制以降低传感节点能耗,传感节点具有体积小、能耗低、不用更换电池等特点。分析自供电条件下,无线传感网络的网络结构,引入中继节点,延伸通信距离。将系统用于电线安全监测,该系统通信可靠、工作时间长、数据实时、人机操作方便,为电线安全的监测提供了技术支持。

Wire fault will cause a fire,to monitor the temperature and current of wire online can prevent the fire occurs. Design a monitoring system with self-powered wireless sensor network, the system includes sensor nodes, relay nodes, routing nodes, server and client. Solving the power supply shortage problem of child node on the wireless sensor network monitoring system with self-powered technology,and reducing energy consumption of sensor nodes by controlling its working state, sensor nodes feature small size, low power consumption and no demand to change battery. To analysis the network structure of the wireless sensor network under the condition of self-powered technology. Add a relay node to extend communication distance. Wire safety monitoring experiments show that the system has the features of reliable communication, long working time, and data acquiring in real time, easily to operate,which will provide technical support for monitoring wire safety.
