毕业设计-基于AT89C51单片机的IC卡读写控制系统设计.pdf

基于 89C51 的 IC 卡读写控制系统设计 毕业设计（论文） 摘 要 在 IC 卡管理应用系统中， 作为 IC 卡数据读写的终端 IC 卡读写器是必不可少 的。IC 卡读写器除了完成基本的 IC 卡数据读写功能外，还要完成数据收集传送、 控制命令输入和显示输出、提供上位机控制管理接口和数据加密处理等等功能。 本文主要介绍了一种 IC 卡读写终端的设计， IC 卡读写终端是一个单片机嵌入式 应用系统。论文介绍了实现 IC 卡数据存储的控制方法， 并以西门子公司的 SLE4442 型逻辑加密卡为基础， 详细介绍了单片机控制 IC 卡数据读写的软、 硬件实现方法。 关键词 ：单片机； IC 卡；控制系统 I 毕业设计（论文） ABSTRACT Being interface device of IC cards, the IC card read-write terminal is necessary in all IC card information management systems. Besides fulfilling the base function of IC card data reading and writing, IC card read-write terminals also need other functions such as collecting data transferring, user command inputting and display message outputting, control interface providing, data encrypting and so on. To design a read-write terminal with needed functions and excellent performance is a key to composing an efficient IC card management application system. This paper introduces the designing of a type IC card read-write terminal mainly. The terminal is a MCU embedded application system.The paper has introduced the reading and writing technique of IC card data.The paper has specified the software and hardware realization of IC card data reading and writing on the base of SLE4442 which is a kind of Smart Card with Security Logic made by SIEMENS.
