毕业设计--基于单片机的智能IC卡读写器设计

基于单片机的智能IC卡读写器设计

摘要：随着社会的进步和现代化程度的不断提高，人类所拥有的信息种类和数量都在成倍地增长，每天都要处理许多与个人有关的信息，而这些信息管理十分不便。因此，在实际生活中IC卡的应用范围非常广泛，它有助于解决问题。IC卡读写器是IC卡和计算机之间的传输媒介，它与计算机之间通过串行口相连，本文主要应用89C2051单片机为核心对SLE4442卡进行读写控制。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。

首先在绪论中介绍了课题的开发意义及功能概述。

其次在主要描述了系统硬件工作原理，并介绍了IC卡SLE4442的内部结构及原理图，论述了本次毕业设计所应用的各硬件接口技术和各个接口模块的功能及工作过程。

本系统是以单片机的基本语言汇编语言来进行软件设计，指令的执行速度快。

最后具体描述了各个功能模块的软、硬件调试。本文撰写的主导思想是软、

硬件结合，以硬件为基础，来进行各功能模块的编写。

关键词：读写控制，单片机，IC卡。

Abstract: Raise continuously along with the progress and modern degree of the society, the information category and quantities that the mankind own all Be becoming doubly a growth, want to handle to be many and personal everyday relevant of information, but these information managements is very inconvenient.The application of the IC card is very extensive in the real life. it contributes to solve problem。 IC card's reading and write a machine is the IC card and of the calculator deliver medium, it goes to connect with each other with of the calculator through a string, this text applies a single slice of 89C2051 machine for the core mainly to the SLE4442 cardses to carry on reading and write a control. The contact type IC card is a newly arisen technique of the IC card realm, it is the outcome that the radio frequency identifies the technique and the IC card technique to combine together.

First introduced in the introduction to the topic of significance and functions outlined.

Secondly the text inside describes the system hardware work principle, and introduce the ICSLE4442internal structure and chip figure, discuss the function and working process of these degree graduation project station applied each hardware interface technology and each interface module. I

This system edits collected materials the language to proceed with single the basic language of a machine the software designs, the instruction carries out the speed quick, save memory. .

In conclusion concretion description soft and hardware debug of each functional module.The predominance thought that this text compose is soft, the hardware combines together, regarding hardware as the foundation, proceeds the plait of each function mold piece write.

Key words: Read and write a control, single slice machine, IC card.
