Ultrahigh-frequency RFID (radio frequency identification) reader protocol conformance testing method

Abstract

The invention relates to an ultrahigh-frequency RFID (radio frequency identification) reader protocol conformance testing method. The ultrahigh-frequency RFID reader protocol conformance testing method includes the steps of a, connecting an upper computer with a frequency spectrum analyzer and acquiring transmitting signals of an RFID reader through the frequency spectrum analyzer so as to acquire reader characteristic signals capable of reflecting all characteristics of the RFID reader; b, processing the reader characteristic signals by the aid of a wavelet transform method so as to acquire reader characteristic transform signals and testing the reader characteristic transform signals to extract and acquire required reader protocol parameters; c, comparing the acquired reader protocol parameters with the standard parameter value stipulated in a protocol to acquire and output comparative results. With the method, conformance of the ultrahigh-frequency RFID card reader protocol can be accurately tested, automation in test can be easily realized, and the method is wide in application and safe and reliable.

Description

technical field [0001] The invention relates to a test method, in particular to a protocol consistency test method of an ultra-high frequency RFID card reader, which belongs to the technical field of protocol consistency test of an ultra-high frequency RFID card reader. Background technique [0002] RFID has become a hot technology in the IT field, and many countries are sparing no effort to promote radio frequency identification technology. The RFID standard has not yet reached a complete agreement in the world. Many organizations have formulated different standards for different frequency bands, and there is a certain degree of incompatibility between the standards. RFID UHF international standards include: ISO / IEC 18000-6, EPC global Class 1Gen and UbiquitousID. Different industries have developed corresponding standards, for example, standards applied to animal identification: ISO TC 23 / SC 19 / WG3, standards applied to transportation and control systems: ISO TC 204, stan...

AI Technical Summary

Problems solved by technology

The above test system solves the problems encountered in the card reader protocol conformance test to a certain extent, but the above method also has limitations

The implementation process of most test plans relies on powerful test equipment, and requires testers to perform manual operations, which not only affects test efficiency, but also affects the accuracy of test results
