【摘要】 矿井配电网的故障定位一直是现场运行中的一大难题,迅速准确地找到故障点对于矿井的安全生产具有重要的意义。本文针对矿井配电网规模小,反射折射多,精度要求高, 传感器误差大的特点,提出了将无线传感器网络应用到故障定位中的新方法,该系统由无线传感器节点,无线网关和故障处理系统等组成,并利用无线节点的多跳组网传输故障后行波信号,通过行波的方向迅速的判断故障区间以进一步判断故障点。本文同时重点探讨了该系统在矿井中应用需要解决的无线电波的接收和合适的网络协议等几个关键问题。更多还原

【Abstract】 The fault location, to find the fault point quickly and exactly, is still a difficult and important problem for the safety production of the coal-mine. Because the distribute power system is small, reflection and refraction are tempestuous, accuracy requirement is very high and sensors have large error, this paper put forwards a new method to solve this problem using wireless sensor networks. Our fault location system is composed of wireless sensor nodes, wireless gateway and fault detection system. It makes use of the multi-hopping of the wireless sensor nodes to transfer the signal after fault occurs, the direction of the traveling wave to judge the fault section and the fault point farther. The paper emphasizes some key problems as receive of the radio wave and a suitable network protocol etc.更多还原
