Coal and Gas Outburst Monitoring System Based on WSN

Based on small-scale and low-cost devices, Wireless sensor networks (WSN) achieves processing, storing, sensing and communicating. It can be applied in the physical dimensions of monitoring environment real-time monitoring, sensing and collecting. After analyzing the existing problems of monitoring technology on coal and gas outburst, the layer model of WSN-based monitoring system was proposed for coal and gas outburst. The emphases were put on sensor nodes and sink nodes. And the software design of micro-sensor was presented as well. Monitoring experiment results show that WSN is suitable for coal and gas outburst monitoring system for its low influence on environment, massive data acquisition and high detection precision. The new monitoring system, which combines WSN and coal mine safety monitoring and measuring system, makes up for deficiency of traditional monitoring techniques. It is an effective measure is to control coal and gas outburst danger source and eliminate the hidden trouble of gas accident. The study developed the technology of coal and gas outburst preventing.
