Design of Coal Mine Positioning System Based on UWB

Aiming at the low positioning accuracy of the existing personnel positioning system in coal mine, the high precision personnel positioning system based on UWB technology is designed, the positioning principle of the system is analyzed, the location base station and location label hardware circuit are designed with STM32 and DW1000 modules as the main body, and the corresponding execution program is compiled. The system coordination test has a good effect, and the positioning accuracy is within 30 cm, which can fully meet the requirements of high-precision positioning in coal mine scenes.
