Research on Coal Mine Roadway Safety Monitoring System Based on Zigbee

With the higher and higher demands to the safety in coal mines and the development of the enterprises themselves, the security problems in coal mines already become the most important ones. Because of many hidden dangers existing in coal mines, the accidents that make the heavy economic losses and personnel casualty occurs frequently in China coal mines. It shows that the existing safety monitoring systems in coal mines has some insufficiencies. By researching on the collection of human physiology information, the design of wireless sensor network node and wireless networking technology, the system applies ZigBee technology into the environment of coal mine roadway safety production, which realizes the detecting of daily work environment of coal mine roadway as well as the real time monitoring of the location and status of the trapped people underground when safety accident happens so as to provide accurate information for rescue.
