基于单片机的IC卡读写系统的实现

毕业论文：基于单片机的IC卡读写系统的实现

摘 要

随着社会的发展和现代化程度的不断发展，人们的信息数量和种类都在加倍地增长，每天都要处理很多和个人有关的信息，而这些信息管理非常不便。因此IC卡应运而生,IC卡使用范围十分广泛，它有助于我们解决问题，使我们的生活变得方便。

首先论述课题的研究背景，课题的设计和意义，设计要求，硬件的工作原理，并给出和介绍了基于AT89C51单片机的IC卡读写系统的内部结构和原理图，阐述了本次毕业设计所采用的各硬件电路和各个接口模块的功能及工作过程。本系统是以C语言来实现软件设计，指令的执行速度快。最后具体描述了各个功能模块的软、硬件调试与分析，撰写的主导思想是软、硬件结合，以硬件为基础，软件为主体，来进行各功能模块的编写。基于AT89C51单片机的IC卡储容量大，安全保密性好，使用方便，具有数据处理能力，使用寿命更长，它除了涵盖传统磁卡的全部功能外，还拓展到许多磁卡所不胜的领域。因此，基于单片机IC卡读写器设计的研究是一个非常有意义的课题。

Abstract

With the development of the society and the continuous development of the modernized level, people's number and variety of information in the double growth, every day to deal with a lot of personal information, and the information management is very inconvenience. So arises at the historic moment, IC card IC card using range is very wide, it can help us solve the problem, make our life become convenient.

First discusses the research background, design and significance of topics, design requirements, the working principle of the hardware is based on AT89C51 single-chip microcomputer as the core, and introduces the internal structure of IC card and the principle of figure, elaborated this graduate design using the hardware interface technology and the function of each interface module and working process. This system is based on C language to achieve software design, instruction execution speed is fast. Last it describes the various functional modules of software and hardware debugging and analysis, the dominant idea of writing is the combination of software and hardware, on the basis of the hardware and software as the main body, to the preparation of the each function module. IC card read-write system based on single-chip computer storage capacity, safety and privacy is good, easy to use, with data processing ability, long service life, in addition to cover the whole function of the traditional magnetic card, it has extended to many fields of magnetic CARDS are by. Based on SCM IC card read-write device design research is a very meaningful topic.
