摘要
RFID技术自1948年问世以来,已有50多年的历史,但其发展却是近几年才兴起的.特别是最近两三年,RFID技术得到了迅猛的发展.RFID技术关键是利用无线电波来进行通信的一种自动识别技术.其基本原理是通过阅读器和粘贴在物体上的电子标签之间的电磁耦合来进行数据通信.与传统的识别技术相比,RFID具有远距离快速识别,数据存储量大、数据可更新等诸多优势.RFID是自动识别技术的高级形式,其独特的技术优势将为人类的生活和生产做出杰出的贡献.以RFID为研究对象,阐述RFID的定义,简述RFID系统的组成部件、工作原理和分类,分析RFID技术的优势所在,并介绍RFID技术的主要应用领域.
RFID has had a history of more than 50 years since its birth in 1948, but it has flourished in recent years. Especially in the last two or three years, RFID technology has been rapidly developed. The so-called RFID technology is referred to an automatic identification technology that uses radio waves to communicate. The basic principle is that using the electromagnetic coupling between the reader and the tag which is pasted at the objects to communicate data. Compared to the traditional identification techniques, RFID has many advantages. It has a long--distance rapid identification, a large quantity of data storage, and the data can be updated. RFID technology is the advanced form of automatic identification. Its unique technical advantages will make outstanding contributions to human＇s life and production. With RFID as the research object, this paper expounds the definition of RFID, gives an outline of the components, operating principles and classification of RFID system, analyzes the advantages of RFID technology and introduces the main fields of application.
