摘　　要：针对矿井火灾源监测定位的难题,提出一种基于WSN进行矿井火灾源监测方案。网络呈网状拓扑结构,以竞争学习方式选取簇头,利用覆盖配置协议控制节点状态,以降低节点能耗、减少信息冗余。节点定位采用RSSI方法测节点间距离,极大似然估计法计算节点位置的机制,并针对矿井实际情况提出利用最小二乘法进行数据拟合建立RSSI模型。According to the difficulty of the mine fire disaster source monitoring, measuring and positioning, base on the wireless sensor network, a mine fire disaster source monitoring and measuring plan was provided. The network was a mesh type topology structure. The cluster head was selected with the competitive learning method, the cover configuration protocol was applied to control the node conditions in order to reduce the energy consumption of the node and reduce the information redundancy. The node was positioned with the RSSI method to measure the distance between the nodes and the maximum likelihood estimation method was applied to calculate the mechanism of the node position. According to the mine actual conditions, the least square method was applied to establish a RSSI model of the data fitting.
