摘　　要：射频识别(RFID)技术应用在物流管理领域日益受到关注,但是,相对较慢的硬件开发速度已成为该技术进一步发展的制约因素。因此本文采用虚拟仪器和数字信号处理技术,结合ISO/IEC 18000-3Mode1协议规范,系统研究了一种用软件代替硬件,实现高频射频识别读写器基本功能的方法。测试结果表明,本系统在带宽、功率、调制精度等性能参数方面达到了设计目标,实现了调制/解调、滤波、编码/解码、循环冗余校验、逻辑控制等射频识别读写器的基本功能。More and more attention is paid to radio frequency identification （RFID） technologies for logistics management application. However it takes a long time to develop a new RFID hardware for a new standard, which limits the further development of RFID technologies and its applications to some extent. Thus, based on virtual instrument and digital signal processing technologies, a method was systematically investigated using software instead of hardware to realize the basic functions of a RFID reader specified by ISO/IEC 18000-3 Mode 1. The measurement results show that the performances of the RFID virtual instrument have achieved the design goals regarding bandwidth, power, modulation accuracy and etc. , and the system has realized the basic functions of a RFID reader such as modulation/demodulation, filtering, encoding/decoding, cyclic redundancy check, logic control and so on.
