Analysis system based on ultrahigh frequency label equipment and frequency characteristic analysis method thereof

Abstract

The invention provides an analysis system based on ultrahigh frequency label equipment and a frequency characteristic analysis method thereof, and the system comprises a setting module which is used for setting the working frequency point and reading time of a reader-writer, the setting module is connected to the reader-writer, and the reader-writer reads a label at each working frequency point and generates reading data; an acquisition module used for acquiring read data of the working frequency point, wherein the acquisition module is connected to the reader-writer; and a determination module used for determining grades of quality of working frequency points and selectiving and sending best quality of working frequency points based on determination rules and reading data, a determinationmodule, wherein frequency of the multiple working frequency points is configured to working frequency with best grades and the determination module is connected with the acquisition module and the configuration module. The method solves the problem that when a plurality of RFID tags are read through a traditional method, the RFID tags are prone to being influenced by the environment, and therefore part of the tags cannot be read.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to an analysis system based on ultra-high frequency tag equipment and a frequency characteristic analysis method thereof. Background technique [0002] In a room where a UHF RFID management system is installed, the RFID tags in the room can be read normally when the antenna is sunny, but one or two tags will always be missed in rainy weather. This may be due to the environment (Mainly due to the influence of moisture) The change causes the frequency of the tag or antenna to change, and some tag frequencies are at a critical value, which makes reading tags unstable. Contents of the invention [0003] In order to overcome the defects in the existing technology, an analysis system based on UHF tag equipment and its frequency characteristic analysis method are provided to solve the problem of being easily affected by the environment when reading multiple RFID ta...
