Benchmark testing system and method for RFID label operating level

Abstract

The invention relates to a benchmark testing system and a method for RFID label operating level. The benchmark testing system comprises a support for labels to be tested, a transceiver and reference antenna support, wherein a transceiver and reference antenna is placed in a standard testing environment. A circulator, a spectrum analyzer, an RFID signal generator and a power meter are placed outside the standard testing environment. The method is that an RFID label chip and the antenna are viewed as a whole body, the input level and the output level of an RFID label system are measured throughthe transceiver and reference antenna by adopting the transmission formula of electromagnetic waves in a free space, the minimum level capable of activating the operation of an RFID label is calculated and the theoretical reading distance of the RFID label is estimated. Through the scientific, repetitive and comparable non-contact measurement of the RFID label power consumption which is one of important indicators determining the performance of the RFID label, the problems that the existing technical indicators are ambiguous and the error of the testing results is great, and assistant decision basis is provided for users to select RFID label products according to the different application requirements.

Description

technical field [0001] The invention relates to the technical field of testing of radio frequency identification technology, in particular to a benchmark testing system and method for working levels of RFID tags. Background technique [0002] The full name of RFID is 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 read and write speed, various shapes, long service life, reusable, large storage capacity, and can penetrate non-conductive materials. Combining RFID readers can realize multi-target identification and mobile target identification , Further, through the combination with Internet technology, it can also realize the tracking of items and the sharing of information on a global scale. RFID technology is used in logistics, manufacturing, public information services and other industries, which can grea...
