摘要
RFID(Radio Frequency Identification,射频识别)通过自动识别帮助机器或计算机识别对象,记录元数据或通过无线电波控制单个目标等。当RFID阅读器与Internet终端相连接时,阅读器可以根据需要全局、自动、实时地识别,跟踪和监视带有标签的对象。研究从基于FPGA(Field Programmable Gate Array,现场可编程逻辑门阵列)的RFID阅读器三个方面入手进行阐述:整体、硬件部分和软件部分。首先论述阅读器的整体构成、天线以及数字基带结构,然后从硬件部分和软件部分细致地对阅读器进行剖析阐述,最后进行了仿真模拟。
RFID helps machines or computers identify objects through automatic identification,records metadata or controls indi⁃vidual targets through radio waves.When the RFID reader is connected to the Internet terminal,the reader can identify,track and moni⁃tor objects with tags globally,automatically and in real time as needed.The research of this paper starts from three aspects of the RFID reader based on FPGA:the whole,the hardware part and the software part.This paper first discusses the overall structure of the reader,antenna and digital baseband structure,and then analyzes the reader in detail from the hardware part and software part.The emphasis is on the research and simulation of the connection design of RFID reader based on FPGA and MCU.
