摘要
电子标签防碰撞是RFID系统中一个关键问题。在射频识别系统中,当阅读器作用范围内有多个标签同时向阅读器发送数据时,会产生冲突,必须采用一种防碰撞算法解决这种冲突。在分析典型的二进制及动态二进制防碰撞算法基础上,采用了一种新的防碰撞算法。经实验证明,该算法能有效解决射频识别系统中多目标识别的防碰撞问题。
Tag anti-collision is one of the key problems of RFID system.In RFID system,when data transaction between more tags and one reader at the same time, the data collision will be caused, so a anti-collision algorithm must be adopt to solve the conflict.In this paper,the binary search algorithm and dynamic binary search algorithm are analyzed in detail, and a new anti-collision algorithm is put forward.The experiment proves that this algorithm is more effective to solve the problem of anti-collision for multi-target recognition in RFID system.
