Response frequency benchmark test system and method for electronic tag in high-speed motion state

Abstract

The invention relates to a response frequency benchmark test system and a response frequency benchmark test method for an electronic tag in a high-speed motion state. The system consists of a standard test environment, a signal source transmitting antenna, a signal source antenna bracket, a spectrum analyzer receiving antenna, a protective cover, a turntable, the electronic tag to be tested, a support table, a driving motor, a driving motor controller, a control computer, a signal source and a spectrum analyzer. In the method, a frequency domain range in which the electronic tag to be tested in the motion state can normally respond to the signal of a reader-writer is obtained by analyzing the response characteristics of an electronic tag product to be tested in the high-speed motion statein different test frequency bands; linear direction speed is simulated by instantaneous speed in the tangential direction of the turntable to realize the high-speed motion of the electronic tag to betested; the frequency response performance benchmark test of the tag in the motion state is realized by simulating the reader-writer to read the signal of the electronic tag to be tested; and a radiofrequency identification (RFID) automatic testing tool and a benchmark test method which are simple, clear and effective can be provided for users.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a response frequency reference test system and method of an electronic tag in a high-speed motion state. Background technique [0002] Radio Frequency Identification (RFID) 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 greatly improve management and operation efficienc...
