A high-precision wireless distance detection system for mining is designed. The detection system is based on the rich resources of STM32. The principle of the two working modes of the system and the related schematic circuit diagram are introduced. Compared with the traditional 51 SCM,STM32 is used. The internal temperature sensor and the ADC circuit can reduce the use of external additional circuitry and increase accuracy while reducing interference and power consumption. Finally,the system was optimized for energy saving so that it can extend battery life under the condition of battery power supply, and can increase the scope of use of the system. Tests in the laboratory show that its accuracy and life are in line with the requirements of coal mines and coal washing plants.
