Application of Wireless Mesh Network Based on Zigbee in Mine Safety Monitoring System

Based on the analysis of the current coal mine safety monitoring technology and application status, through the scheme and system design and Network Simulator (NS) simulation analysis, a security monitoring system based on the combination of ZigBee technology and Mesh network is developed. The system uses ZigBee technology to build underground wireless sensor network, collects the underground environmental data from sensors installed on nodes, and then transmits the collected information to the ground monitoring host through the Mesh network, thus the real-time monitoring of underground environment and personnel position is achieved. The system has the characteristics of high reliability, large network coverage and good mobility. It has guiding significance for the coal mine safety monitoring and prevention of safety accidents.
