Title: Design of RF Conformance Test System Based on Virtual

Instrument

Abstract:

Radio Frequency Identification (RFID) is a technology which uses the wireless to obtain and store the information without contacting with the tags. RFID technology is not only one of the most important technologies in corporate and social informalization, but also the core technology in the Internet of Thing Industry. However, the complexity of working condition may cause RFID system to fail in its practical performance. A series of test procedures must be implemented before the investment and application of RFID equipment.

This paper introduces the structure, operating principle, assorting and its merits and drawbacks of the RFID system based on ISO / IEC 14443 protocol. It presents the coherent criterions, including data rate, modulation, coding, decoding, and frame structure. According to ISO / IEC 14443 protocol, the transmitter module and receiver module are designed in Labview. And then a RFID test system is built by using the NI Modular Instruments PXI-5610 upconverter, PXI-5600 downconverter and PXIe-5641R based on Software Defined Radio. And the architecture of hardware and software is presented. It also presents the design of the PCD prototype aircraft. Finally, according to the test protocol, the test system completes the RF conformance test, and the test results are analyzed and discussed in the paper.

In the end of the paper, a summary of the whole subject is presented. And the paper puts forward some aspects that are worthy of further study and optimization. Finally, further research of RFID is discussed.
