基于无线传感器网络的煤矿安全监测监控系统

Safety Monitoring and Control System of Coal Mines Based on Wireless Sensor Networks

针对现有煤矿监控系统受布线区域的限制,不能延伸到作业面,以及布线复杂、扩展性差、维护成本高、控制手段落后等缺点,设计了一套基于无线传感器网络的煤矿监测监控系统;在地形比较开阔的主巷道区域,架设有线以太网,对于地形相对狭窄的支巷道,尤其在形状不规则的开采面,采用无线传感器网络;控制手段采用先进的专家系统,仿真结果证明网络的良好性能,吞吐速率高,约为34kbit/s,网络延迟小,并稳定在0.0105s,能满足矿井网络通信的要求。

The existing monitoring and control system of coal mine is limited by wiring area with complex routing, can not extend to workingsarea, has poor extensibility and high maintenance costs, and its control means is backward, according to this, designed a coal mine measuring and monitoring system based on wireless sensor networks. Set up wire Ethernet in more open roadway areas, and use wireless sensor networks in narrow sub--roadway, especially in irregular mining face. Advanced expert system is used in control of system. Simulation results shows that the network＇s performance designed in this paper is good, throughput rate is high, about 34kbit/s, network delay is in 0. 0105 seconds. So this system can meet the requirements of network communication in mine network.
