Design of Monitoring System for Coal Mine Safety Based on Wireless Sensor Network

This paper designs a monitoring system for coal mine safety based on Zigbee wireless sensor network. The monitoring system collects temperature, humidity and methane values underground of coal mine through Zigbee sensor nodes around the mine, and then transmits the data to information processing terminal based on ARM. The terminal sends the data to the ground through Ethernet, and then the monitoring centre monitors the data and publishes them to the LAN for remote users to inquire. If the data is ultra-limit, the system can send SMS to related personnel of safety. This system has realized the real-time monitoring of working surface.
