基于FPGA的RFID阅读器设计

Design of RFID Reader Based on FPGA

作为一项具有广泛应用前景的技术,RFID阅读器近年来已在多个领域发挥了重要作用。由于单片机的开发周期长且批量小,因此,采用FPGA为核心来设计高频、远距离的阅读器。经验证,它能够快速、准确地实现曼彻斯特编码的译码并进行CRC校验。设计的通用异步收发器实现了数据的接收和发送,具有电路形式简单、移植方便等优点。

As a technique having widespread applicable prospect, the RFID reader has elaborated great effects in many fields. Since developing single chip computer takes long period, and producing in small lots, the high frequency and long distance reader is designed by adopting FPGA as the kernel. It is verified that the reader is able to decode Manchester code and realize CRC check. An universal asynchronous transceiver is also designed to implement sending data and receiving data. The design features simple circuitry, and easy to transplant.
