摘    要:本文介绍由作者自行设计的一种新型磁卡输入系统的硬件原理和接口软件.该系统采用并行方法将磁卡机的三态信号传送给微机,非设计者根本无法破译磁卡上的编码.接口软件用8088汇编语言写成,巧妙的用程序代替了一部分硬件逻辑,注重了软件与硬件的时序配合.该系统已试运行,性能稳定、可靠.

关 键 词:磁卡  读卡机  微机接口  硬件  软件

Abstract:he principle of a new type of magnetic card input systme designed by the authors is introduced in this paper.The system transmits three state signals of card to microcomputer by parallel method.The code of the magnetic card can be decoded only by the designers themselves,others cannot decode it. The interface software system which can be used to replace some hardware logic is programmed by 8088 assembly language.This system,being tested in Shandong Qingdao Sanlian Electronic Company,focuses on cooperation of software and time order of hardware and proves to be stable and reliable.
Keywords:magnetic card reader  computer interface  hardware  software
