Abstract: In view of problems of dangers installing, frequent line breakage and hard maintenance existed in normal wired monitoring system of supporting quality for roadway bolt and steel mesh, a wireless monitoring system of roadway supporting quality was designed. The wireless monitoring system takes roadway hazardous area section as monitoring object, solves reliability problem of transmission backbone network by ZigBee and WiFi wireless data communication protocol. The application result shows that the system is easy to install and maintenance, which optimizes roadway parameter and improves safety of mining.
