ANTI-COLLISION SEARCH ALGORITHM FOR RFID BASED ON BREADTH-FIRST DYNAMIC BINARY

射频识别技术(RFID)在超高频段的应用将成为物流商业开发的主流,对于排除阅读器识别多个电子标签发回信号的电磁波干扰,实现快速、准确地信息识别,抗碰撞的搜索算法是最为关键的因素。研究了基于广度优先动态二进制搜索算法,并进一步提出优化方案,从技术上切实提高了射频识别系统的效率。

The application of radio frequency identification（RFID） in ultra-high frequency band will become the mainstream in logistics industrial development.To eliminate electromagnetic interference on RFID reader when identifying a number of return signals from the electronic tags,and to achieve rapid and accurate information identification,the anti-collision search algorithm is the most crucial factor.In this paper,we study dynamic binary search algorithm based on breadth-first,and further propose the optimization scheme,thus the efficiency of radio frequency identification systems is improved practically in terms of technology.
