毕业论文 论文题目 接触式IC卡读写器设计 日 期 2009年5月28日 摘要 本文首先介绍了IC卡的产生、发展、应用及其国际标准，然后介绍基于单片机的接触式IC卡的读写的设计过程，此项设计主要是实现单片机对接触式IC卡（SLE4442）的读和写。此设计实现对卡的密码（PSC）校验，读出数据，修改数据，修改密码等功能。本文根据国际标准ISO/IEC 7816及DIN S=10标准，以SLE4442为例，详细分析了逻辑加密卡的工作时序，设计了逻辑加密卡与微处理器之间的接口电路，成功地实现了两者间的数据交换。本文对系统各模块进行了方案论证与选择，重点论述了系统各模块的硬件电路设计，对软件设计和软硬件综合调试进行了全面地分析与说明。本设计以单片机STC89C52RC作为主控制器，以LCD1602作为显示器，用4×4矩阵键盘作为输入设备，具有友好的人机界面。经过调试，本设计的硬件与软件都实现了设计任务的各项指标。 关键词：STC89C52RC，SLE4442，ICIn this paper, the generation, development and application of IC card are introduced at first, as well as the international standar. Then the paper introduces the designed process of the read-write of contact IC card based on single-chip microcomputer. The design mostly make it come true that the single-chip microcomputer achieve the read-write of contact IC card (sle4442). The design complete the function of the code (PSC) verification, reading data, modification data, modification code of the IC card, and so on. According to the standard ISO/IEO 7816 and DIN S=10, taking SLE4442 for example, the interface device(IFD) between IC card and MPU is designed by the thorough analysis of the working timing of the synchronous logical encryption IC card, which realizes data exchange at the bottom of IC card successfully. The paperproves and choices the programme of the system modules, focuses on the hardware circuit de equipment sign of the system module, analysis and describes software design, hardware and softwarede bugging completely. The design use STC89C52RC as the main controller, use LCD1602 as displaying , use 4 × 4 matrix keyboard as input equipment, and having a friendly man-machine interfaces. After debugging, hardware and software of the design achieve the indicators in designed task.
