The study on the Coal Mine Safety Integrated Monitoring and Early Warning System DesignUsing the S-MAC Protocol

Network monitoring system is handled by the automatic collection of web content, sensitive word filtering, intelligent clustering classification, topic detection, thematic focus, statistical analysis, a number of links to realize the need of the supervision and management of network public opinion, and ultimately the formation of public opinion, special reports, analysis reports, statistical reports, decision-making and management have complete control of public opinion, the dynamic, to make the right to guide public opinion, provide an analytical basis. The current monitoring system has some drawbacks such as small monitoring scope and less real-time. Coal mine safety monitoring and early warning systems are designed based on wireless sensor network in this paper. This system realized channel access to S MAC protocol, and transmitted environment information collected such as CO, CH4, temperature, humidity and my roof pressure, etc. to the monitoring station and realized real-time monitoring of the mine working environment parameters. Modeling simulation is performed on the wireless network structure by applying OPNET software, and the results show that in the wireless transmission condition, 20 nodes sent 1000 data packets, more than fifty of which are received. Wireless transmission network performs well.
