A method for identifying RFID tags by a single reader with tail code continuous identification quantity as an index

Abstract

The invention relates to a method for quickly identifying RFID tags by a single reader with tail code continuous identification quantity as index, belonging to the technical field of radio frequency identification. The invention first judges whether the tag tail code which is successfully identified at present exists in the tail code table, and then determines whether the tail code continuous identification quantity is increased or not. When the amount of continuous recognition of the tail code is increased to a value, the reader selects a partial missing tag to preferentially process the region with high recurrence frequency of the tail code, so that the method of processing missing tag in the process of identifying a brand-new tag can shorten the identification time of the tag. At the same time, the invention is well applied to the simulation environment of the small and medium-sized warehouse, which reduces the waste of resources caused by the repeated identification tags of the reader, and greatly improves the efficiency of the tag identification.

Description

technical field [0001] The invention relates to a method for identifying an RFID tag by a single reader using the continuous identification amount of a tail code as an index, and belongs to the field of radio frequency identification technology (RFID). Background technique [0002] At present, there are two methods for the identification of RFID tags in the environment of small and medium warehouses. [0003] One method is to use multiple readers to identify tags, because the recognition area of ​​a reader is much smaller than the area to be identified, in order to ensure that all the tags in the area can be identified, multiple readers must be installed. However, this method will increase the purchase cost, installation cost and maintenance cost of the reader, resulting in excessive spending. If a single mobile RFID reader can be used to identify the tags, this will effectively reduce the required cost of the system. [0004] Another method is the label recognition method...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a method for identifying RFID tags with a single reader based on the continuous identification amount of the tail code as an index, so as to solve the technical problems in the mobile identification RFID tags of the single reader under the small and medium-sized warehouse: 1) due to repeated tail codes Time slot waste caused by high occurrence rate; 2) RFID readers also need to increase the time required for tail code reprocessing; 3) There are many problems such as the number of missed tags
