RFID定位机制在矿井人员监控系统中的应用

In this paper, RFID(Radio Frequency Identification) technology and various kinds of RFID location methods are introduced as research base. The variety of traditional location algorithms are simulated and analyzed. In order to offset the limitation of these traditional algorithms as Chan and Taylor, the location results of Chan are used as original value of Taylor Series Expansion algorithm, and the performance of location is improved effectively. In order to reduce the influence by NLOS, a simple modified algorithms is improved. At last, a program design is raised which is suit for the environment of mine under the ground. The system can give a accurate position of miner who is under the ground. When there is a accident happen, the control system will help searchers know the quantity and position of miners.
