Experimental design of gas monitoring system in mine safety helmet based on wireless sensors networks

In order to solve such problems of the mine cable gas monitoring system as high costs, inconvenient maintenance, hindering wiring and unmovable monitoring information points, a mine safety helmet is designed, based on wireless sensors networks, which studies the hardware design, gas concentration calculations and its dynamic compensation algorithm, as well as the experimental design of gas monitoring system in mine safety helmet so as to ensure the correct calculation of the gas concentration. The innovative point of this essay is the combination of the ordinary LED cap lamp and the wireless sensors networks, which ensures a real-time, dynamic collection of the information of the gas concentration around the workers.
