RF ID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-RF ID RFID technology because of its simple, convenient application, currently in storage, logistics, library management, drug management and other areas are widely used. But the practice, in many cases there is a field in the RF reader and a number of electronic tags.

When reading multiple RFID tags simultaneously counting occurs when the channel contention. Existing solutions are ALOHA and the Binary Tree method, and the two methods based on the improvement of the method. However, the existing method of counting the low efficiency of the existing methods based on the collision, we propose a new method of ALOHA and Binary Tree s new anti-collision scheme, designed to further enhance the application of multi-tag RFID inventory efficiency
