Automatic monitoring system for coal mine safety based on wireless sensor network

The environment of mine exploitation is special and dangerous, how to real-time monitor and collect information on the various nodes, how to master the location of miner and the environment at any time, it is a difficult problem for Coal mine enterprise to urgently solve. This paper presents the system design of monitoring system for coal mine safety constructed by MSP430F and nRF2401, and gives the hardware design of sensor nodes and the flowchart of software. The sensor groups of the system intensively monitor temperature, humidity and other parameters in the underground mine, parameters measured are sent to wireless communication module by the micro-controller. The system can be used to confirm the position of miners and monitor environmental conditions in the underground mine, which will improve the level of monitoring production safety and reduce accident in the coal mine.
