Abstract: A two way information transmission terminal is proposed to solve the problem that underground miner is unable to understand his surrounding environment well. The structure and features of the embedded personal information terminal based on Wi-Fi network technology are given in detail; a low power consumption chip of GS1011 is used as the key chip of smart terminal embedded in a mine-lamp. The main principle of the smart terminal is analyzed and the algorithm of real time location and tracking for the underground miners is designed. Combining with the modeling technique of 3D mine tunnel, a virtual reality displaying system is built. The system is adopted by the internet of things demonstration project in Jiahe Coal Mine, Xuzhou, and obtained a good effect. The main functions of the system include initiative perception of the miner security based on his surrounding environment, the communication with ground and other miners, and real-time location and the tracking management for the miners.
