摘　　要：为解决目前RFID读写器难以支持多协议、多应用等问题,提出了以虚拟无线电技术实现RFID读写器的思想。根据ISO/IEC 18000-6C协议标准,阐述了基于虚拟无线电技术的系统构架,对链路频率、处理时延、同步耗时等RFID系统物理层和协议层主要参数进行了详细分析,并在构建的虚拟无线电平台上完成无源超高频射频识别系统的信号传输及协议一致性测试,验证了基于虚拟无线电技术实现RFID读写器的有效性。基于虚拟无线电技术的RFID读写器在PC机中完成标签识别层处理和基带信号处理,不需要专门的硬件平台,能够支持多频段、多协议、多应用,且开发周期短。RFID reader based on virtual radio technology is presented, in order to solve the difficulties of current RFID reader hardly supporting multi-protocol and multi-application. System architecture based on virtual radio technology is introduced briefly, according to ISO/IEC 18000-6C protocol standard, and some key parameters of physical and protocol layer such as back-scatter link frequency, processing delay and synchronous time-consuming are analyzed in detail. The protocol conformance test and signal transmission of passive UHF radio-frequency identification are accomplished by virtual radio technology, and the validity of RFID reader based on virtual radio technology is testified. RFID reader based on virtual radio technology can not only process tag-identification layer and baseband signal successfully on the PC, compatible with multi-band multi-protocol and multi-application, but also greatly shorten development cycle without specialized hardware platform.
