The Realization Of Identify In Many Cards For The Radio Frequency Identification Systems

In the Radio Frequency Identification (RFID) application system, we oftenencounter the problems in which many moving targets come into the same workingfield. In order to avoid the signal disturbance between targets, this articlestudies arithmetic of many RFID electronic labels being dealt with andanalyses arithmetic theory of anti-collision in the system of time intervalALOHA method and binary system searching method RFID system. This articleanalyses with mathematic model the average response time and throughput ofthe whole Radio Frequency Identification system and provides the solution tothe anti-collision.This article also discusses improvement method of binary system searchingmethod in anti-collision-dynamic binary system searching method. Dynamicbinary system searching method deals with how to divide the data into two parts,Transmit-receive part of data of each other. So that the data amounttransmitted can be reduced by half and transmitting time can be shortened,meanwhile improve efficiency of the RFID system.On research of the theory and method of Anti-conflict of multi-labelreading technology, this article provides the concrete soft and hardwaresolution to realize and also the details, verifying the correctness ofsolution to the technological theory.
