针对目前RFID系统工作频率多样,各类标准众多且差距较大,不适合多种标签同时应用的情况,提出了基于软件无线电及LabVIEW设计RFID阅读器的思想。通过加载不同的软件代码,仿真阅读器可以实现对不同频段,符合不同标准的RFID标签进行读写。通过与标准阅读器的读取结果进行比对,仿真阅读器实现了对RFID标签携带信息的读取,节约了需要配置各种不同类型阅读器的成本。
As nowadays the operating frequencies of RFID system are diverse, system standards are too many and have great difference, which is not suitable for variety of tags to be used simultaneously, a method to design a RFID reader based on software radio and LabVIEW is proposed. By loading different software codes, the simulation reader is able to operate the RFID tags in accordance with different standards and different frequency bands, including reading and writing. Comparing the read result with that of the standard reader, the simulation reader realized the readout of the RFID tag information successfully, with which the cost of having to configure the different types of RFID readers to deal with variety of tags is reduced.
