基于无线传感器网络的煤层自燃火源定位监测

Position Monitoring and Measurement of Seam Spontaneous Combustion Fire Based on Wireless Sensor Network

为了实现采空区自燃火源定位监测,基于无线传感器网络(WSN)技术,提出一种煤炭自燃预测预报监测系统的总体设计,在该系统中无线传感器按照一定的网络的拓扑控制机制和火源定位机制,高精度在线实时测量煤炭自燃隐患区点及其附近的温度等自燃特征参数以实现煤层自燃火源定位。对比试验表明,该系统控制方便、工作稳定,能实现可靠的无线数据传输,而且可以较准确地判定煤层自燃隐患发展程度及其范围,对安全防治煤层自燃有很好的指导作用。

In order to monitor and measure the position of the spontaneous combustion fire in the goal, base on the wireless sensor network technology, the paper provided the general design on the monitoring and measurement system of coal spontaneous combustion prediction and early-warning. The wireless sensors in the system, based on the certain network topology control mechanism and the fire positioning mechanism, could be high accurately to an on time measure the spontaneous combustion danger area and the nearby temperature and other natural feature parameters in order to position the spontaneous combustion fire. The comparison tests showed that the system with an easy control and reliable performance could have a reliable wireless data transmission and could be accurately to judge the seam spontaneous combustion danger development and its scope, which could be a good guidance to the safety prevention and control of the seam spontaneous combustion.
