Abstract: In view of problems of being unable to sense underground environment parameters and failing to form two-way real-time communication network between underground and ground caused by single function of miner lamp , an intelligent miner lamp based on embedded real-time operating system was designed. The lamp takes STM32 chip as main control center, and collects environmental temperature, gas concentration and personnel movement status by using temperature sensor, gas sensor and acceleration sensor respectively. The NRF24L01 wireless communication module reads status of underground positioning and material label to obtain personnel position and material information; data is uploaded to the ground server via WiFi for display and storage. The lamp has both manual alarm and automatic alarm functions, the host computer can send information to achieve two-way communication between underground and ground. Test results show that the intelligent miner lamp is stable and reliable, easy to operate, and has high real-time performance.
