Benchmark testing system of RFID label arranging density and method

Abstract

The invention discloses a benchmark testing system of RFID label arranging density and a method. The system consists of a test controller, a spectrum analyzer, a standard reader-writer signaling unit, a transmitting antenna, a receiving antenna, a transmitting antenna bracket, a receiving antenna bracket, a basal plate and a basal plate bracket. With the same input energy, the adjacent label interference degree received by the test label in multi-label deployment is evaluated by testing the comparison of a reverse scattered signal when the RFID label is in different arrangement modes and different arrangement density and the reverse scattered signal when the label exists independently. The test system and the method can assist a user to select the RFID label with smaller mutual interference and higher energy conversion efficiency according to the characteristics of article arrangement in an application environment before RFID deployment, and further provide a simple, clear and effective RFID automatic testing tool and a benchmark testing method.

Description

technical field [0001] The present invention relates to the technical field of testing radio frequency identification technology, in particular to a system and method for testing the arrangement density of RFID tags. Background technique [0002] RFID stands for Radio Frequency Identification (Radio Frequency Identification), which is a non-contact automatic identification technology realized by radio frequency technology. RFID tags have the characteristics of small size, fast reading and writing speed, various shapes, long service life, reusability, large storage capacity, and can penetrate non-conductive materials. Combined with RFID readers, multi-target recognition and moving target recognition can be realized. , and further through the combination with Internet technology, it can also realize the tracking and information sharing of items on a global scale. RFID technology is used in logistics, manufacturing, public information services and other industries, which can g...

Problems solved by technology

[0004] The distribution relationship of RFID tags in space can be represented by a spherical coordinate system, that is, a relative reference system is established with an RFID tag as the center of the sphere, and the spatial positions of other tags can be represented by spherical polar coordinates, but expressed by a spherical coordinate system The position of RFID tags in space is obviously too complicated. The original intention of considering the arrangement of tags is to test whether there will be mutual interference between RFID tags, which will affect the reading rate. Considering the specific situation in practical applications, only representative The location can be inspected
