ANTI-COLLISION SYSTEM AND METHOD WITH MOVING TAGS IN RFID SYSTEMS

摘要

The present invention relates to a collision avoidance system and method considering the RFID tag mobility. More specifically, the present invention relates to a collision avoidance system and method considering the RFID tag mobility to improve the recognition rate can not be recognized by recognizing the RFID tag likely to increase the recognition rate of the RFID tag when the RFID tag to move preferentially. The present invention in terms of the technique disclosed in order to achieve the above technical problem, RFID reader, and transmits the recognition start command to recognize the number of RFID tags in their recognition area. After that the RFID reader and the recognition received by the start command of the RFID tag number of collisions with each C _th (collision threshold) compared to the number of collisions than the C _th greater than or equal to provide a collision avoidance method considering the mobility of the RFID tag to favor recognition attempt in the binary tree (binary tree) interval. ;
