摘要

   信息技術(shù)的發(fā)展給生產(chǎn)和生活帶來巨大的變革，非接觸式射頻IC卡的普及和廣泛應(yīng)用也是其中的表現(xiàn)之一。非接觸式IC卡沒有機(jī)械觸點(diǎn)，通過無線方式與讀寫設(shè)備進(jìn)行通訊，與接觸式IC卡相比具有操作快捷、抗干擾性高、可靠性高、安全性好、便于“一卡多用”、多種工作距離等特點(diǎn)，深受用戶的好評(píng)和歡迎，具有廣闊的市場(chǎng)前景。
 基于實(shí)際應(yīng)用項(xiàng)目的需要，本課題開發(fā)了一種讀寫距離小于10mm的非接觸式IC卡讀卡器。本文將從非接觸射頻讀卡器系統(tǒng)的開發(fā)應(yīng)用角度，闡述IC卡的組成及其工作原理、射頻卡讀卡器的工作原理、天線的設(shè)計(jì)、單片機(jī)對(duì)讀卡器的程序控制、讀卡器系統(tǒng)與PC機(jī)的通信。

Abstract
 
 The development of information technology brings a huge transformation for the production and daily life. The popularity and widespread application of the contactless radio frequency IC card is also one expression of the information technologies. The contactless IC card owns favorable comment and welcome from users and has broad market prospects, for having no mechanical electronic contact, carrying on the communication with the read-write equipment through the wireless way. Compared with the contact IC card, it has many characteristics, such as fast operation, anti-jamming, high reliability, fine security, easy to a card with multipurpose， handling with work distance and so on.    Basing on the actual need of the project, this subject has developed one kind of read-write distance which is smaller than 10mm contactless IC card RWD. From the angle of the application of developing contactless radio frequency RWD system, this paper will elaborate the IC card composition and the principle of work, the radio frequency RWD principle of work, antenna's design, the programmed control, the RWD system and the PC correspondence.
