钨矿井下破损高压导线对WSN节点电磁干扰机理的建模分析

Analysis on Modeling from Electromagnetic Interference of Broken High Voltage Wire in the Tungsten Ore Underground on WSN Nodes

钨矿输电高压导线遍及整个巷道,常发生电晕和火花放电,由此带来的电磁辐射对无线传感器网络节点造成严重干扰。为此,对钨矿高压导线进行辐射场强建模仿真计算,结果证明,降低干扰后温度数据的错误率由25%下降到10.4%,建立的矿井模型和电磁辐射仿真结果能够很好地反映实际运行状态,对实际应用中传感器节点的布置和高压导线的布线具有很强的理论指导意义。

Tungsten mine transmission voltage wire spread all over the tunnel,and corona and spark discharge happens all the time. Electromagnetic radiation generated by corona and spark discharge will causes serious interference with the wireless sensor network nodes. Modeling and simulation of the radiation field intensity of tungsten mine transmission voltage wire,the experiment showed that error rate of temperature data was decreased from 25% to 10. 4%,and the established mine model and simulation result of the electromagnetic radiation were able to reflect its actual running state. And it will provide a strong theoretical guidance for sensor nodes arrangement and high-voltage wiring in practical applications.
