Zigbee-based prediction system for coal rock dynamic disasters

With respect to prevention and control of coal or rock dynamic disasters such as coal and gas outburst and rockburst, the authors, based on KBD7 gas prospector, adopted state-of-the-art wireless transmission Zigbee technology in designing a wireless network system under B/S (browser) mode for monitoring of coal or rock dynamic disasters. By integrating such high technologies as computer technology, network technology and Zigbee, the system performs reasonable operation and sharing of electromangetic signals reception, and establishes a platform of analysis, prediction and warning for coal or rock dynamic disasters for coal mine wide access network, providing quick, convenient and clear-cut services to decision making. In addition, the paper introduces the basic theory and technological features of Zigbee technology and B/S mode, demonstrates the system structure and database design, and explains the results of the system.
