摘　　要：射频识别是一种非接触自动识别技术,近年来广泛应用于物流管理、车辆收费、门禁管理等方面。UHF频段RFID技术由于可实现远距离和快速通信而受到越来越多的关注。文章提出了一款基于ISO/IEC18000-6C协议的超高频读写器的设计方案。该设计射频部分以奥地利微电子公司的AS3990射频收发芯片为核心,数字部分以FPGA芯片为主控器,通过并口连接实现读写器的读取,并能提高多标签读取效率。Radio Frequency Identification （RFID） is a non-contact automatic identification one, which is widely used in logistics, automatic charge system, access control system, and so on. The RFID system operating at UHF band has been paid more and more attention due to its longer reaching distance and fast speed. This paper presents a design scheme of UHF reader based on ISO/IEC 18000-6c protocol. The RF reader chip AS3990 from Austriamicrosystems is chosen as the core, and a FPGA chip is chosen as the master controller in the digital part. This system uses parallel connection to accomplish the reading function of the reader and can improve the identifying efficiency of multiple tags at one time.
