煤矿智能救援系统,通过井下无线传感器网络监测数据,为系统提供安全预警支持。由于井下巷道错综复杂,不同的节点部署方法会影响井下监测数据传输的可靠性。为了节省无线传感器网络资源及维持网络的可靠通信,提出一种分级部署无线传感器网络节点方法,主干网节点采用最大通信距离算法部署,备用节点采用分级部署方法。仿真结果表明该方法有助于提高网络通信的可靠性,延长网络寿命,提升网络健壮性。
Mine intelligent rescue system, through the underground wireless sensor network monitoring data for the system to provide security early warning support. Due to the complexity of underground tunnels, different node deployment methods will affect the reliability of downhole monitoring data transmission. In order to save resources of wireless sensor network and maintain reliable communication of the network, a method of hierarchical deployment of wireless sensor network nodes is proposed. The nodes of the backbone network are deployed with the maximum communication distance algorithm and the standby nodes adopt the hierarchical deployment method. The simulation results show that this method can improve the reliability of network communication, extend the life of network and enhance the network robustness.
