Research and Implementation of Key Technologies of Goaf Coal Spontaneous Combustion Wireless Monitoring System

In order to make up the deficiencies in the goaf coal spontaneous combustion monitoring of mine safety monitoring system. Provide the most direct and effective data for the early identification and prediction of the goaf coal spontaneous combustion fire. The NRF905 Radio frequency (RF) communication technology had been adopted to design the goaf coal spontaneous combustion monitoring system, which accompany by SCM, sensors, Clock circuit and CAN bus communication technology. The paper given the overall design of the system, and key technologies of system had been made research and implementation. Experimental tests showed that the device layout simple, networking fast, the effective data of each node position could have been made real-time collection.
