摘要
简述了无源射频识别系统的组成、工作原理及数据碰撞问题。针对射频识别系统的技术要求和应用特点,提出一种基于时分多路的动态ALOHA反碰撞方法,并对其工作原理、可行性及实现过程进行了分析和论证。该方法无需增加硬件开销,应用成本低,适应性强。
This paper describes briefly the composition and operation principles and digital collision of Radio Frequency Identification (RFID). In accordance with technical requirements and application features of RFID, this paper advances a method of dynamic ALOHA base on TDMA for anti-collision of RFID, analyzes and demonstrates the operation principles, feasibility and implementation process. This method dispenses with adding hardware, so it has such characteristics as less application cost and high adaptability.
