RFID系统读写器与电子标签硬件结构分析

射频识别(RFID,Radio Frequency Identification)是一种非接触式的自动识别技术,也称为"无线条形码",射频识别以非接触性、识别速度快、可以多卡识别等优于其他自动识别技术的特性受到广泛重视。应用非常广泛,如动物识别、门禁控制、生产线自动化控制、停车场管理、物料管理等等。对RFID系统的工作原理进行了介绍,重点分析了读写器硬件结构,电子标签硬件结构,希望对RFID系统的开发有所帮助。

RFID Reader and Transponder Hardware Structure Analysis

RFID（Radio Frequency Identification） is a non-contact automatic identification technology,also known as ＂wireless bar code＂.RFID,for its non-contact,high-speed identification,multi-card recognition,is superior to other automatic identification technologies,and thus attracts much attention.RFID has very wide applications,such as animal identification,access control,automatic control of production line,parking management,material management and so on.This paper describes RFID’s working principle,emphatically analyzes the reader’s hardware structure,the transponder’s hardware structure,hoping that this could be helpful to the development of RFID system.
