Study of the Mine RFID-based Personnel Positioning System
Considering the problems of studying and applying RFID (radio frequency identification) -based mine personnel positioning system at present, the enhanced DFSA (Dynamic Frame Slotted ALOHA) is proposed with the aid of theoretical analysis and computer simulation. The estimation method of the number of tags in the location area, relationship between frame size and number of positioning tags, method of grouping the tags and the performance of enhanced DFSA are investigated, and the relationship between positioning errors and underground sensors distribution is simulated. Based on above, the paper discusses the problems of mine RFID-based positioning. The results indicate that the proposed enhanced DFSA can effectively enhance the utilization of radio frequency channels and reduce the probability of collisions between the tags. And the positioning errors are estimated according to sensors distribution. The mine personnel positioning system plays a key role in improving safety management and disaster rescue, and can be as the out-in and key point of establishing the coal mine internet of things. Currently, problems should be urgently solved that the mine personnel positioning system can not work and play a substantial role in the rescue due to power out and explosions, etc. when the mine disasters occur.
