Application of WSN Fire Monitoring System in Coal Mining

Targeted at the potential fire in coal mine production, this paper proposes a coal mine fire monitoring system based on Zig-bee technology, and discusses the network data transmission process in the system. When the system is applied to an actual coal mine, it achieves a sound fire monitoring effect. The wireless sensor network (WSN) coal mine fire monitoring system consists of such three subsystems as data acquisition subsystem, control center subsystem and emergency response subsystem. With sensor nodes as the basic unit, the WSN is divided into five parts: sensor module, treatment module, wireless communication module, location module and power supply module. The system can monitor the air temperature, humidity and smoke concentration of fire in the coal mine, and provide effective basis for monitoring department to make decisions on fire prevention and control measures. The on-site monitoring test shows that, in the event of a fire, the WSN can monitor the trend of fire in the coal mine effectively, reflect the temperature distribution in details, and issue alarms accurately. The conclusion offers a theoretical reference for the development of coal mine fire monitoring technology.
