Position prediction in mine personnel RFID positioning system based on shortest path principle


The RFID-based positioning equipment, which is widely used in mine operation such as coal mine, has the advantages of low cost and maturity. It can locate human effectively so that it could improve the production safety situation and provide guarantee for disaster prevention and relief. However, the traditional RFID technology has the drawbacks of small monitoring range and no orientation which cause larger deviations and blind area in personnel locating. In this paper, we design the coal mine personnel positioning system based RFID. The system could track the underground person and draw the movements between the RFID base stations by the shortest path principle and algorithm. Combining the factors of time and experience data, the system can also predict the person position in blind area of the base stations. That improves the localization ability of RFID system.
