Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0037] With the rapid development of RFID technology, the number of manufacturers of related products has gradually increased, and different applications require different tags. The variety of RFID tags has also risen to hundreds, and new products are constantly being introduced. In order to choose the product that can best meet the needs of users among the many RFID tags, it is necessary to conduct special tests on the performance indicators of RFID products. The response frequency of RFID tags is one of the important performance indicators of RFID tag products. The RFID tag response frequency refers to the frequency domain in which the RFID tag can correctly respond to the RFID tag signal read by the reader under a certa...

Abstract

The invention provides radio frequency identification device (RFID) label response frequency standard test system and method. The system comprises a standard test environment, a signal source emitting antenna, a receiving antenna, an RFID label to be tested, a signal source antenna bracket, a receiving antenna bracket, a label bracket, a signal source, a spectrum analyzer and a control computer. The method obtains a frequency domain range in which the RFID label to be tested can normally respond signals of a reader by analyzing response characteristics of an RFID label product in different frequency bands under the condition that input energies are kept same. By simulating the reader to read the signals of the RFID label, the frequency range of the RFID can be tested, and an RFID automatic test tool and a standard test method with simpleness, accuracy and efficiency are provided for a user.

Description

technical field [0001] The invention relates to the field of RFID technology, in particular to a system and method for benchmarking the response frequency of an RFID tag. 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 greatly improve management and operation effic...
