Design of Underground Mining Personnel Locating System Based on nRF24L01

An underground mining personnel locating system which takes nRF24L01 to establish data base-station for communication was demonstrated in the paper. The location and identification of the E-tag wearing mining personnel can be accomplished through the signal transmit-receiving of every base-station's transceiver. The concerned information will be transmitted to the control station through the data substation to accomplish the personnel and equipment location, thus enhancing the underground mining safety production, disaster relief ability and management efficiency.
