| الملخص (بالإنجليزية): |
In order to overcome the shortcomings of binary anti-collision, such as more communication data and communication time, novel dynamic binary anti-collision algorithm is proposed. In the new algorithm, the ID information is preprocessed in the first communication between the reader and tags, and then only the collision bits are handled in the next process. The binary-tree is constructed by the deleted collision bits accordingly. The bits before the highest collision bit followed by "0" constitute the left subtree. The bits before the highest collision bit followed by "1" and the bits between the highest collision bit and the second highest one constitute the right subtree. Then the tags are identified at leaf level. The new algorithm is improved for both reader and tags, so that it reduces the amount of communication data and improves the recognition efficiency.

| Abstract (Chinese): |
针对现有二进制防碰撞算法通信数据量大、存在冗余信息的缺点, 提出了 一种新二进制防碰 撞算法。新算法在阅读器与标签的首次通信中首先进行信息预处理, 后继识别过程中只处理冲突位, 然后 利用每次探测得到的碰撞位信息构造二叉树。最高碰撞位之前的部分后接一个"0"为左子树, 最高碰撞位 之前的部分后接一个"1"+两个最高碰撞位之间的部分为右子树, 在叶子结点实现标签的识别。该算法从 阅读器和标签两方面同时进行改进, 减少了通信量, 提高了识别效率. [ABSTRACT FROM AUTHOR] |
