In recent years, the national demand for coal is increasing at a high speed, and the coal industry is greatly developed, but because the underground operation of a mine is far away from the ground, the terrain is complex, the environment is severe, major and extra-large accidents of a coal mine happen frequently, and effective control on disaster accidents is not realized yet. Due to the particularity of the coal mine industry, at present, the underground personnel management is difficult, the aboveground personnel cannot timely master the dynamic distribution and operation conditions of the underground personnel and the mine car, once an accident occurs, the aboveground personnel lack reliable underground information, the efficiency of emergency rescue and relief work and safety rescue is low, and the effect is not ideal. After the accident happens, the positions of underground production operators and mine cars, the withdrawing routes of the persons in danger, the underground environment monitoring condition and the like can be accurately judged, and powerful information guarantee is provided for the rescue scheme. The Zigbee-based personnel positioning system mainly realizes networking under the whole mine by deploying network nodes of Zigbee at different positions under the mine, but the condition that the whole system is paralyzed due to damage of one node often occurs due to certain irresistible factors, so that great inconvenience is brought to rescue. And the high cost is a key factor for limiting the application. At present, active RFID technology is generally used for coal mine positioning, more reading heads are deployed in a mine tunnel, active tags worn by miners actively broadcast information outwards, and the reading heads upload the collected information to a control center server, so that the miners are positioned. In the method, the Received Signal Strength Indicator (RSSI) is used for positioning, and more reading heads must be deployed in the tunnel to obtain higher accuracy, so that the cost is increased.

When the existing mine car positioning device on the market is used, dust easily enters the equipment when the positioning device dissipates heat due to the working environment, so that the equipment is damaged. Therefore, the mine car positioning equipment with low-power-consumption accurate positioning technology is provided.
