Abstract

The invention relates to a RFID protocol conformance test platform based on ZYNQ and a working method thereof. The RFID protocol conformance test platform comprises a reconfigurable RFID baseband processing system and an extensible interface; the reconfigurable RFID baseband processing system comprises a core processing unit, a PCI interface logic unit, a PLX9054, a high-speed storage unit, a QSPI storage unit and a SD card interface circuit, wherein the high-speed storage unit, the QSPI storage unit and the SD card interface circuit are respectively connected with the core processing unit; the extensible interface comprises a CPCI interface, a FMC interface, a PMOD interface, a display interface circuit and a user control interface circuit, wherein the FMC interface, the PMOD interface, the display interface circuit and the user control interface circuit are respectively connected with the core processing unit; and, after being sequentially connected to the PLX9054 and the PCI interface logic unit, the CPCI interface is connected to the core processing unit. The RFID protocol conformance test platform has relatively high integration level and extendibility and supports a real-time simulation module, successful and failure mode, a monitoring mode and the like; and thus, multi-mode mixing is realized.

Description

Technical field [0001] The invention relates to a ZYNQ-based RFID protocol consistency test platform and a working method thereof, and belongs to the technical field of voice recognition and Beidou positioning. Background technique [0002] The RFID protocol conformance test specification is continuously developed with the development of the RFID standard. The purpose of formulating the test specification is to determine whether the characteristics of the device under test are consistent with the provisions of the protocol standard. Now the International Organization for Standardization ISO and EPCglobal have formulated corresponding test specifications based on the published RFID protocol standards to guide standardized and reliable RFID protocol conformance testing. [0003] RFID is an emerging technology in the field of wireless communication. Its protocol conformance testing still relies more on the combination of traditional instruments such as signal generators, spectrum anal...

AI Technical Summary

Problems solved by technology

[0003] RFID is an emerging technology in the field of wireless communication. Its protocol conformance test still relies more on the combination of traditional instruments such as signal generators, spectrum analyzers and oscilloscopes. However, due to the fact that RFID technology has common characteristics of wireless communication , and has its unique particularity, it is difficult to build a complete protocol conformance test system with a combination of traditional instruments

The reasons are as follows: (1) The test of RFID readers and tags is quite different from the test of traditional equipment. The real-time communication process cannot be completed by using pre-generated signals. The test system must have the ability to generate signals in a very short time in real time. Traditional The signal generator cannot meet the timing requirements of the protocol; (2) The key to the consistency of the RFID protocol lies in the integrity of the test, and the unit under test must be tested for a complete physical layer and protocol layer according to the consistency test; (3) RFID There are many types of protocol standards, including LF for short-distance communication; HF frequency band standard, and UHF (microwave band standard) for long-distance communication. The standards in each frequency band are also different due to different working modes and data.
