Design of Monitoring System for Coal Mine Safety Based on MSP430 and nRF905

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 describes the design of monitoring system for coal mine safety constructed by MSP430 and nRF905, which has described the structure of the system, working principle, and gives the hardware design of sensor nodes and the flowchart of software. This system is used for On-line monitoring of coal mine safety with the character of simple structure, low cost, low power consumption and so on, which will improve the level of monitoring production safety and reduce accident in the coal mine.
