Abstract

The invention relates to an RFID reader-writer multi-label processing flow optimization method. The method comprises the following steps: dividing response of an RFID tag to an inventory order into three types: having collision, having no reply and having reply, and setting an applicable decision criteria for a reader-writer; increasing decoding success rate of a signal processing module of the reader-writer for collision label reply information; optimizing recommended multi-label collision prevention processing flow in GJB7377.1-2011, deleting low-efficiency orders in multi-label processing and increasing utilization frequency of higher-efficiency orders; and setting continuous collision threshold and continuous idle threshold involved in the multi-label processing flow in the test experiment. The advantages are that the method can greatly reduce the probability of label omission of a military reader-writer during single-round inventory, and can improve label reading efficiency of the military reader-writer; and the method reduces idle time and collision time, and improves multi-label reading rate.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, and mainly relates to the optimization of a multi-label anti-collision process of a military reader-writer. Background technique [0002] The RFID system mainly includes RFID tags and RFID readers. Radio frequency identification is the use of readers to inventory one or more electronic tags. Military RFID reader is a type of radio frequency identification reader, which has the characteristics of high reliability, high stability, high security and so on. Multi-label inventory is an important part of the application of military RFID readers, and multi-label inventory is inseparable from the multi-label processing flow of military RFID readers. The advantages and disadvantages of the multi-tag processing flow directly affect the efficiency of the multi-tag inventory of the RFID reader. The key to optimizing the multi-tag processing flow of the RFID reader is how to effective...
