摘要
针对RIFD标签识别过程中的碰撞问题,在动态二进制防碰撞算法基础上提出一种改进的防碰撞算法。该算法在动态二进制算法基础上结合了后退式二进制算法,使阅读器不用每次从头开始发送请求命令,而且改进算法中引入了计数器,以控制标签状态信息。分析表明,该算法可以降低阅读器发送请求的次数,同时可以减少标签识别所需的时间。
In this paper,in view of the occurrence of collision when identifying labels simultaneously in the RFID system, we in- troduced an improved dynamic binary anti-collision algorithm. This algorithm combines the idea of dynamic binary algorithm and regressive binary algorithm,which avoid the reader starting sending request commands every time. In addition, the algorithm pro- poses a tag counter that control the status of tag. The analysis shows that the algorithm can reduce the number of times that the reader can send the request, and also reduce the time required to identify the label.
