Abstract：Radio frequency identification technology,Anti-collision problem is to improve the efficiency of the system reads the key issues.This paper analyzes the ALOHA anti-collision algorithm and binary search algorithm based on the traditional anti-collision algorithm.And propose an improved dynamic binary search algorithm. Using Manchester encoding can accurately identify the characteristics of the collision position, when the reader detects a collision position, the collision position only needs to record the highest and second highest bit position of the collision, and set these two positions as the number of bits of the next query command, so that the amount of data transmission system, the transmission time is greatly reduced, the improved algorithm is more competitive than the binary search algorithm.
