摘要

本论文介绍了一种基于非接触式IC卡的门禁管理系统，非接触式IC卡是IC卡领域的一项新兴技术，它是射频识别技术和IC卡技术相结合的产物。射频识别(Radio Frequency identification，简称RFID)技术是最近几年发展起来的一门新的自动识别技术。它利用射频方式在非接触式IC卡和读卡器之间进行无线双向通信，完成目标识别和数据交换。而卡上电路的工作电源由读卡器发出的电磁波能量提供。由于非接触式IC卡具有操作快捷、防碰撞能力强、工作距离远、安全性高、便于“一卡多用”等特点，在身份识别、自动收费和电子钱包等领域具有接触式IC卡所无法比拟的优越性，具有广阔的市场前景。基于实际应用项目的需要，本课题开发了一种读写距离为100mm的非接触式IC卡门禁系统。

从门禁技术的发展出发，首先介绍了非接触式IC卡的特点、种类、组成以及国际标准。然后介绍非接触式IC卡门禁系统所涉及的技术。在此基础上，论文详细地阐述了非接触式IC卡门禁系统的硬件和软件设计，读卡器的硬件设计包括蜂鸣器驱动电路、RS232通信电路、TX522读卡模块；软件设计包括读卡器和外围电路的应用程序设计和主程序设计三个部分，并介绍了上位机界面设计。

根据以上的研究工作，设计了一个基于非接触式IC卡的门禁系统。

Abstract

This article introduces a kind of Entrance Guard System that is based on Radio Frequency Identification cards. Contactless IC Card is one kind of new technology in the field of IC card，which is the combination of Radio Frequency Identification technology and IC card technology. Radio Frequency Identification technology is a new technology of auto identification in recent years. Wireless and bidirectional communication between reader and contactless card is their communication mode to identify the goal and to swap data by radio frequency identification. The power of IC card circuit is supplied by the power of electromagnetic wave from reader. Because contactless IC card has some advantages over common IC card such as its high working speed，good anti-collision quality and long working distance，there will be a good prospect for it in many fields，such as automatic pricing，identify distinguishing，electric wallet and so on. The contactless IC card reader is one of the key devices of a contactless IC card system. We developed one kind of contactless IC card Acess control system，which is one part of a project and has about 100mm working distance.

On the basic of the development of Entrance Guard System，at first this paper generally introduces the contactless IC card，including its feature，type，composing and international standard. Then it introduces the technology of Entrance Guard System. Based on these，the paper discusses the design of the contactless IC card reader in detail，including the circuit design and software design. The reader's circuit is made up of buzzer drive circuit，RS232 communication circuit，TX522 card r eader module and antenna circuit. The software design includes programming of other circuit and programming of main program. At last the paper introduces the interface design for host computer.

According to the study above,designed a access control system based on the contactless IC card.
