高可靠性矿用瓦斯爆炸防控系统

High Reliability Monitors System for Mineral Gas Explosion

瓦斯爆炸是煤矿井下最大的安全隐患之一,笔者针对瓦斯爆炸受瓦斯浓度和高温点火源两个必要条件制约的特点,提出了基于无线传感器网络的瓦斯爆炸防控系统。本系统能够同时监控瓦斯浓度和温度两种信号,与传统的瓦斯监测系统相比,其监控可靠性更高;另外本系统采用了无线通信技术和传感器网络技术,减少了信号传输线路,同时减少了维护工作量,应用起来更灵活。

The gas explosion is one of the biggest security risks of the coal mine underground.According to the characteristic that gas explosion is restricted by two essential conditions of gas density and high temperature ignition source,the author proposed a system to prevent and control the gas explosion based on the wireless sensor network.The system can monitor the concentration and temperature of gas simultaneously,which has more reliability compared with the traditional gas monitor system.Furthermore,this system has used the technology of wireless communication and the sensor network to reduce Signal line and Maintenance workload.The system will be more flexible for use.
