摘要
针对煤矿井下巷道特点,指出煤矿井下无线Mesh网络适于组建链状网络拓扑结构,并应结合巷道具体环境进行电磁波衰减理论分析和节点间距设计;针对现有的路由协议不能满足煤矿井下无线Mesh网络链状拓扑结构的要求,结合MIC判据,提出了一种反应式路由协议与先验式路由协议相结合的方法;在此基础上,给出了基于无线Mesh网络的煤矿应急救援系统的整体结构及特点。实验结果表明,把无线Mesh网络应用到煤矿应急救援系统中,提高了救灾工作的安全性、可靠性及灵活性。
The paper pointed out that chain network topology is suitable for underground wireless Mesh network and electromagnetic wave attenuation analysis and node space design should be considered combining with concrete roadway environment according to characteristics of underground roadway. It proposed a method combining reactive routing protocol and proaetive routing protocol with MIC criterion for that current routing protocol cannot meet with requirements of chain network topology of underground wireless Mesh network. It gave general structure and characteristics of coal mine emergency rescue system based on wireless Mesh network on the above basis. The experiment result showed that applying wireless Mesh network in coal mine emergency rescue system can improve safety, reliability and feasibility of rescue work.
