摘要
提出一种基于ZigBee通讯技术的煤矿瓦斯浓度监测的井下无线通信网络,该网络中无线通信节点模块呈树状结构分布,实现井上监控室到井下主巷道和分巷道工作面之间的通信,实时检测多个采煤工作面瓦斯浓度状况.该网络还可实现人员定位功能,矿工的矿帽上安装一个带有固定编号的无线通讯模块,将矿帽编号发送至附近无线通信节点,无线通信节点将该节点编号及矿帽编号通过网络一起发送至井上监控室,通过检测矿帽编号及无线节点的编号即可判断该矿工的位置.
A wireless communication network which monitors the methane concentration in coal mine based on ZigBee technology has been proposed. The network consists of many wireless communication node distributing in dendriform configuration, can realize the wireless communication among the ground monitor platform and the underground work platforms of mine, detecting methane concentration. The network can been used in personnel location in mine. A wireless communication unit with special serial number is fixed in the cap of miner, when the serial number is sent to the proximate communication node, the serial numbers of the unit and the node will be send to the ground monitor platform, and the manager can gain the position of miner by the serial numbers.
