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.
