Aiming at the complex special underground environment and the seal of the external network, based on the Zigbee wireless communication technology and industrial Ethernet technology a comprehensive and normalized coal mine monitoring system was built. By way of GIS using AutoCad to transform virtual map, the realtime display and join operations of down hole virtual map information were realized. Finally the system through a web virtual map could be displayed on a PC computer and carried on join operations on the map, so as to realize the remote monitoring function.
