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
