RFID-based coal mine personnel positioning system and positioning method

The invention discloses an RFID-based coal mine personnel positioning system and positioning method. The system comprises a plurality of hydraulic supports with built-in RF signal transmitters, a crossheading centralized control center, an upper computer, a plurality of switches, card readers connected with the switches, and identification cards carried by coal mine personnel. The RF signal transmitter transmits a low-frequency RF signal, the identification card reports the RF signal and an identification signal of the identification card to the crossheading centralized control center through the card reader after receiving the low-frequency RF signal, and the crossheading centralized control center transmits the received information to the upper computer. According to the invention, the distance between the whole personnel or any personnel and the RF signal transmitter can be analyzed in real time, the underground distribution condition of the personnel can be known at any time and can be tracked and monitor
