基于Intel R2000的UHF RFID读写器的设计

摘要

A novel scheme of reader-writer of UHF RFID system was designed. The transceiver chip Intel R2000 and at91sam7s256 were used in the reader-writer. The design conforms to ISO18000-6C and EPC global Gen 2 standard, whose operating frequency is 840～960 MHz and its distance is 10 m. The hardware configuration and the software flow of the system are proposed, and the relevant RF circuit design is also introduced.%设计出一种超高射频识别系统(UHF RFID)读写器设计的新方案.该读写器采用了Intel R2000收发器芯片、AT91SAM7S256微控器,方案符合ISO 18000-6C和EPC global Gen2标准,工作频率为840～960 MHz,标签识别距离可达10 m.重点给出了读写器硬件系统组成和软件工作流程,同时介绍了相关射频电路.
