Study on the Wireless Real-Time Monitoring and Safety Forewarning Techniques of Mined-out Area Based on GDAS Technology

In view of the present situation of stability monitoring of mined-out areas in mines,a wireless real-time monitoring scheme which is based on ZigBee wireless networks and GDAS network middleware was proposed. Displacement and stress -strain sensors are used to monitor the deformation and failure activities of surrounding rock. The monitored data is transmitted to the industrial computer through ZigBee wireless network. The real-time display of monitored data and the safety forewarning information can be achieved based on the GDAS platform. The mine decision-maker can achieve the long-distance real-time monitoring of mine safety by Web browser,and timely make relative countermeasures to dangerous events.
