Design of Roof Abscission Layer Displacement Monitoring System Based on RF Communication
Abstract：In order to improve safe production of underground coal mine,designs one roof abscission layer displacement monitoring system based on RF（Radio Frequency） communication.The monitoring sub-station calculates roof displacement,and then it transfers collected data to the next sub-station.Data is transferred by using relay mode.Finally these data are transmitted to the ground monitoring host computer through CAN bus.Sub-station uses low power design,which has the functions of regular boot and auto-off.The system uses battery and wireless communication that can reduce installation and maintenance workload.
