摘 要
伴随着电子信息技术的发展,尤其是IC卡技术的广泛应用,人民的日常生活变得日益的方便和快捷。IC卡是一个正蓬勃发展的边缘产业,一个与我们生活越来越密切的产业。目前“一卡通”正在许多领域得到应用,如公交系统、税控管理、宾馆服务、医疗保险等。在普及因特网和计算机的大潮涌来时,IC卡扮演着日益重要的角色。IC卡读写器是IC卡与应用系统间的桥梁,在ISO国际标准中称之为接口设备IFD(Interface Device)。IFD内的CPU通过一个接口电路与IC卡相连并进行通信。IC卡接口电路是IC卡读写器中至关重要的部分,根据实际应用系统的不同,可选择并行通信、半双工串行通信和I2C通信等不同的IC卡读写芯片。非接触式IC卡简介又称射频卡,成功地解决了无源(卡中无电源)和免接触这一难题,是电子器件领域的一大突破。
本文设计了单片机控制IC卡数据读写的软/硬件、LED显示以及与PC机之间的串口通信。介绍了以单片机AT89C51为核心的IC卡系统的设计。

ABSTRACT
With the development of electronic information technology, especially the wide application of IC card technology, the people's daily lives become more convenient and faster. IC card is the edge of a booming industry, a life more closely with our industry. At present, "Card" is applied in many fields such as public transportation systems, tax management, hotel services, and medical insurance. Popularity of the Internet and computers in the coming tide of time, IC card to play an increasingly important role. IC card reader is a bridge between systems and applications, in the ISO international standard interface device called IFD (Interface Device). IFD within the CPU via an interface circuit and the IC card is connected and communicate. IC card interface IC card reader circuit is a vital part of the difference based on the actual application system, choose parallel communication, half-duplex serial communication, and I2C communications, such as different IC card reader chip. Introduction of non-contact IC card, also known as radio frequency card, successfully resolved the passive (no power supply card) and free access to this problem, the field of electronic devices is a major breakthrough.
In this design, we discuss IC card data read and write MCU hardware / software, LED display, and with the serial communication between PC machine. Introduced to the AT89C51 microcontroller as the core of the design of IC card system.
