摘要:
目前射频识别技术(RFID)有着广泛的应用,但由于 RFID 的标准众多,不同标准的标签需要不同的阅读器进行识别,这给 RFID 的应用开发带来了不便。 首先,介绍了 RFID 技术和软件无线电技术的发展状况;其次,介绍了软件无线电技术的基本原理和关键技术,分析了 GNU Radio 开放软件无线电平台的软件体系结构和开发模式,包括软件 GNU Radio的组成要素和运行流程,并且介绍连接的硬件设备 USRP 的母板和子板的基本知识。 将软件无线电外设 USRP 和软件GNU Radio 相结合,设计并实现了 RFID 读写器与标签之间的无线通信信息采集。 搭建了 GU-RFID 平台,对相关功能进行了测试。 最后,利用 GU- RFID 平台完成了超高频 RFID 系统的 ASK 数字调制,为进行 RFID 通信的 MAC 层研究和安全隐私保护技术研究提供了平台基础。
Abstract:
At present,RFID technology has been widely used,but due to the numerous RFID standards,different stan-dards of tags need different RFID readers for identification, which brings inconvenience to the application of RFID.Firstly, the development of RFID technology and software radio technology is briefly introduced. Secondly,the basic principles and key technologies of software Radio technology are introduced,the software architecture and development mode of GNU Radio open software Radio platform are analyzed,including the internal structure and working process of GNU Radio,and the basic information of USRP main board and sub-board is discussed. Using the architecture of software Radio USRP + GNU Radio platform, the wireless com-munication information collection between RFID reader and tag is designed and realized. GU-RFID platform is built and relevant functions are tested. Finally,the ASK digital modulation of UHF RFID system is completed by using the GU-RFID platform,which provides the platform foundation for the research of MAC layer and security privacy protection technology of RFID communication.
