Coal mine safety production has always been the focus of attention from all walks of life. Once a coal mine safety accident occurs, it will not only affect the normal production and operation of enterprises and the supply of energy, but also affect the happy life of many families. However, in the process of ensuring the safety production of coal enterprises, in addition to strictly following the operating rules to avoid safety accidents, the occupational safety and health of coal workers is also particularly important. According to the follow-up investigation of China Occupational Safety and Health Association, the proportion of the number of occupational patients and the number of deaths from safety accidents in China's coal enterprises is 6:1, and the situation of occupational disease hazards is also quite severe. However, it is not easy to pay close attention to the health of workers, locate personnel positions, and issue safety warnings in a mine hundreds of meters deep. In order to solve this problem, Shandong Energy Group's Beidou Tiandi Co., Ltd. has created a set of occupational health big data management platform according to the needs of the group. This platform can display the number of downhole personnel, vital signs and real-time location information of the day through personnel positioning GIS map. In order for this management platform to play a real role, it is necessary to have a terminal device that can realize the monitoring function of positioning and vital signs, and also can meet the underground safety production specifications. Only when the continuous collection of relevant data into the system can the original design intention of protecting the safety of personnel be realized. The smart watch is obviously the most ideal terminal acquisition device. However, the smart watches on the market are mainly designed for ordinary consumers, which cannot meet the requirements of the safety production specifications in mines. In the end, Beidou Tiandi Co., Ltd. selected Huawei's terminal for commercial cooperation after a lot of screening to transform the Huawei Watch smart Watch. Through in-depth communication with Huawei, Beidou Tiandi Co., Ltd. has jointly created a solution combining explosion-proof watches and intelligent miner's lamps to achieve the functions of physical sign monitoring and personnel positioning of underground personnel; Huawei connects with the customer's app data through the Health platform to realize the daily exercise health management function. At present, 2500 Huawei WATCH GT 2 and 500 Huawei WATCH 3 have been successfully delivered. Subsequent products are still being delivered. Specifically, in the daily operations of miners, employees need to wear Huawei smart watches correctly before going down the well, so that enterprises can conduct real-time detection on the vital signs of underground employees and the working environment around employees, and conduct real-time platform early warning on possible environmental problems; In case of emergency, downhole operators can also use wearable equipment to send SOS for help. The management personnel on the well can view the location information of all personnel in real time through the positioning system to ensure the safety of all personnel. At the same time, rescuers can also carry out accurate rescue according to the real-time location to improve the rescue efficiency. In addition, from the software level, the combination of the SDK docking solution provided by Huawei and the Kuanghong operating system can expand more abundant intelligent application scenarios to meet other requirements of the construction of smart mines. At present, both parties are adding Huawei Kuanghong system to intelligent miner's lamp, watch, portable instrument and other equipment, with the help of Kuanghong's "soft bus" and "near-field discovery
