基于能耗均衡的矿井皮带无线传感器网络构建

针对煤矿井下皮带监测装置布置范围广、工作环境恶劣、不便于排查故障和进行管理等问题。设计了一种基于ZigBee技术的皮带监测方案：通过在运输皮带两侧放置ZigBee节点，组成无线网络，实现传感器信息的实时传送。重点研究了网络能耗问题。为了平衡各传感器节点的能耗，最大化网络的生命周期，提出一种基于成功传输率的优化模型，并用opnet对其进行仿真。得到了该优化模型在丢包率、端到端时延、吞吐量、包误码位数、信噪比方面与矿井皮带监测无线传感器网络传统的能耗模型的5张性能对比图．图中曲线证明了在仿真开始500s后该模型明显优于传统的模型。

Construction of wireless sensor networks in mine transport supervisal system based on energy balanced

Aiming at some problems existing in belt conveyor supervisor,such as wide-rang distribution,terribk operation environment,difficult to troubleshvoting and manage,a scheme to supervise belt conveyor based on ZigBee is proposed.In this scenario,the goal of detecting sensors which were placed along belt conveyor in line was achieved by forming wireless sensor network(WSN).At the same time,we studied on energy balance models,and an optimal model based on probability of receiving one bit successfully was propose...
