摘要

 本文将对基于AT89C52 MCU和ZLG500A模块的mifare卡读写卡器进行研究，进而设计基于非接触IC卡的门禁系统的刷卡控制部分。
 非接触式IC卡(Contact less Card)技术是最近几年发展起来的一项新技术。它是将无线识别技术和IC卡技术集于一体，成功解决了无源(卡中无电源)和非接触这一难题，是电子器件领域的一大突破。随着社会经济和科技的发展，非接触式IC卡技术己广泛地应用于各种行业，特别是公共交通、无线通信、身份识别、金融交易和安全防卫等行业。门禁系统是一种管理人员进出的数字化管理系统。非接触式IC卡由于其较高的安全性、较好的便捷性和性价比成为门禁系统的主流。
 本毕业设计课题实现一个Mifare 1非接触式IC卡读写卡器，该读写卡器由ZLG500A位读写射频（RF）模块和Atmel的AT89C52微控制器组成。开发的系统具有与Mifare 1非接触式IC卡数据通信功能，可以实现数据缓冲、无线唤醒、和信息处理等功能，课题内容包括设计一基本应用系统线路，开发模块和驱动程序等。

Abstract

 This paper will have a research on the read-write card of mifare based on AT89C52 MCU and ZLG500 module ,then I will design the intelligent entrance guard system based on contact less card.
 The Contact less Card technology is a new technology which developed in this recent years. It sets the wireless technique and the IC card technology in a body.  It solves the difficult problem of no power (in card not have power source) and non-contact successfully, is a big breakthrough in the domain of electronic device. Along with the social economy and the technical development, Contact less Card technology have appliesd in various profession widely, especially in the professions of mass transit, wireless communication, status recognition, financial transaction safe defense and so on. The entrance guard system is one kind of  digitization management system of the administrative personnel pass in and out. Contact less Card become the entrance guard system's mainstream because of the high security, good convenient and the performance-to-price ratio.
 This graduation project topic realizes read-write card of mifare 1 Contact less Card, the card-reading and writing is composed of the ZLG500A of radio frequency (RF) modules and the Atmel AT89C52 micro-controller. And the development of the system has functions of data communication with the mifare 1 Contact less Card, can achieve data buffer, wireless wake-up call, and information processing ,and other functions. The subjects includ the design of a basic line application system, the development of modules, drivers and so on.
 
Key words: RF cards, readers, ZLG500A, AT89C52
