接触式 IC 卡读写器的设计 摘 要 所谓接触式 IC 卡读写器，就是通过触点接触的方式来进行对 IC 卡设备的读 写的设备。 本设计通过大量的测试数据和多次试验，以功能模块的形式设计了各个部分 电路，进行了原理图的编写，并详细阐述了各个电路部分的工作原理及实现的功 能，并绘制并制作了 PCB 电路图进行焊接和调试，并在硬件电路设计完成的基础 上，利用 Keil Cx51 软件的 C 语言编译系统，并结合 ISO 7816 协议中对 IC 卡操 作过程和传输约定的部分进行详细分析，对 MCU 部分代码进行编写，并进行大 量的计算和调试，不断修改和完善其功能，最终实现的接触式 IC 卡读写器的功能。 本 IC 卡读写器能够对常规 IC 卡进行读写操作，并把操作的结构直接返回给 PC 机，使用户完全可在 PC 机上对读写器进行想要的一切操作，从而使操作更为 简便和直观。 关键词：IC 卡，读写器，μPSD ，接口设备 III 接触式 IC 卡读写器的设计 Abstract This paper is designed contactless IC card reader writer. The so-called contactless IC card reader, is through contact contact approach to the IC card devices to read and write. By a lot test and simulation, the design of the contactless IC card reader writer hardware circuit is described by the function block, to introduce a module in the form of various parts of the circuit functions and principles, and elaborated on various parts of the circuit and the realization of the principle functions of the final Of the schematic and PCB circuit analysis. On the hardware circuit design is completed on the basis of Keil Cx51 use the C language compiler software system, combined with ISO 7816 agreement in the IC card operations and agreed to transfer part of a detailed analysis of the MCU part of the code for the preparation and a lot of Calculation and debugging, and constantly improve its function, and eventually realize the contactless IC card reader functions. The IC card reader to the conventional IC card to read and write operation and the structure of the operation to return directly to a PC so that users can complete on a PC for the reader to all the operators, so that more operations Simple and intuitive.
