摘要：Combined with lock algorithm, retreat algorithm and multithreaded processing thoughts; it puts forward an anti-collision algorithm based on multi-threaded RFID lock position. RFID reader sends a quad command, RFID tag response the information of collision position, reduce the amount of data transmission; Fused with lock and multi-status thoughts, the algorithm checks the lock position of card numbers, and continuously separates the status of card numbers in the searching process. Using multithreaded processing idea, tags are classified by the algorithm, and collision handling time is shortened. The algorithm solves the problem of idle thread by tag group. From the test results, compared with the original algorithm, this algorithm reduces the times of collision identification and digit number of data transmission, and improves the system performance
