摘要
RFID射频识别技术由于其技术简单,应用方便,当前在仓储,物流,图书管理,药品管理等各方面都广泛应用。但实际应用中,很多情况是在射频场中存在一个阅读器和多个电子标签。当阅读器同时清点多个电子标签时,就会出现信道争用。现有的解决方案是ALOHA和Binary Tree方法,以及在这两种方法基础上改进的方法。但现有的方法清点效率较低,因此在现有的碰撞方法基础上,提出一种结合ALOHA和Binary Tree方法的新的防碰撞方案,旨在进一步提高RFID应用的多标签清点效率。
There are widespread applications of RFID technology currently in such as storage, logistics, books, medicines management and so on. Because it is so simple and convenient. In practical condition, there are always more than one tag existing in the radio field of the reader. So channel collision is inevitable and to be resolved. ALOHA and Binary Tree Algorithms are the two typical schemes to resolve collision problem, but they are less efficient. In this paper, we propose a new anti - collision algorithm based upon the combination of the two methods to improve the inventory efficiency.
