Design of Intelligent Collecting Device of Mine Pressure Based on ZigBee

In view of problems of complex routing, high labor intensity and inflexible setting of monitored points existed in traditional wired monitoring system of mine pressure, an intelligent collecting device of mine pressure based on ZigBee wireless sensor network was designed. The device is distributed in roadway and working face as node of ZigBee wireless sensor network, data collected by each node is aggregated to relate base station through ZigBee wireless sensor network and then is transmitted to central control room through wired network. The actual application shows that the device has characteristics of convenient setting, high precision and meets with requirement of dynamic extension of tunneling face.
