Abstract: In order to optimize the underground mine management, enhance the security of underground work, and improve the personnel positioning accuracy, a underground personnel positioning system based on the WiFi technology with the fast transmission speed, long effective distance and high reliability is built after comparing with several kinds of major wireless location technology.The off-line training and on-line positioning was made with the algorithm for fingerprint recognition, and the position calculation was done with Euclidean distance formula.Experiments prove that this system is feasible and the positioning accuracy is improved effectively with positioning error less than 5 m.
