基于物联网的煤矿实时监测的拓扑可靠性设计与优化分析

Design and Optimal Analysis of Topological Reliability to Remote Real-time Monitoring of Coal Mine With IoT

物联网技术很适合对煤矿进行实时监测,但其可靠性需进一步探究和完善。根据煤矿巷道窄长且干扰因素多等特点,提出了一种适合煤矿安全监测的三维均匀物联网节点部署方法。在保障监测数据准确的基础上,进一步研究了提高物联网拓扑可靠性的相关机制,如节点之间的距离冗余、簇头节点的非等量备份冗余,并对相关的参数进行量化分析。从理论分析和仿真的结果看,所提出的方法具有监测区域覆盖程度高、能耗均衡和灵活可扩展等特点,对提高煤矿安全监测的拓扑可靠性具有显著效果。

Intemet of Things （IoT） is very suitable for remote real-time monitoring on coal mine,however its reliability needs to be further studied and improved. Based on the characteristics of coal mine, such as long and narrow tunnel and severe intefference,a 3D uniform IoT sensor deployment method which is suitable for the major hazards monitoring is proposed. Fur- thermore ,the related mechanisms to improve the topological reliability of IoT are studied on the basis of accurate monitoring da- ta, such as the distance redundancy between nodes and the unequal redundancy of cluster head. At the same time, several rele- vant parameters are quantitatively analyzed. From the view of theoretical analysis and simulation results, the method have char- acteristics of high coverage, balanced energy consumption, and flexible sealability, which have significant effect on improving the topological reliability of coal mine major hazards remote monitoring with IoT.
