Positioning system and positioning method of mine locomotive beacon

The invention provides a positioning system of a mine locomotive beacon. The positioning system of the mine locomotive beacon comprises an industrial personal computer, a displayer, a transmission interface box, beacon machines and markers. At least two beacon machines are arranged, and the beacon machines are scattered in mine wells. A marker is arranged on each mine locomotive. The displayer and the transmission interface box are both in signal and electrical connection with the industrial personal computer. The beacon machines are in signal and electrical connection with the transmission interface box through RS485 buses. The beacon machines are in infrared signal and electrical connection with the markers. The markers are further in RFID signal and electrical connection with the beacon machines. The infrared communication distance between the beacon machines and the markers is 3 meters. A positioning method mainly comprises the steps that the beacon machines send infrared position coding signals, the markers receive the infrared position coding signals and attach local codes on the infrared position coding signals and send the signals in RFID signals, the beacon machines receive signals and upload the signals, and the industrial personal computer processes the signals and displays the signals. The positioning system of the mine locomotive beacon is simple in structure, convenient to achieve, low in cost, and accurate and convenient to position.
