IC卡计算机收费管理系统的实现

Architecture of IC Card Fare Collecting Management System

本文介绍IC卡计算机收费管理系统的实现方案,并对组成该系统各部分的设计思想及相互联结方式作了一个描述,Visual Basic实现了前台收费系统软件,后台数据库管理采用了较为流行的网络数据库SQL Server,为了使得收费机、IC卡读写器和计算机能够共存于一个网络系统中,用 VisualC++编写了对SLE4442卡和AT45D041卡进行读写的函数,作成了动态链接库供VB调用,通过RS232和RS485进行通讯,使系统中的硬件能够和谐地联接.

The paper discusses the architecture of 1C card fare management system. It describes the design thought of all parts of this system and their relations. The fare management system of front end is realised by Visual Basic. We adopt the popular network database SQL Server as the back end database. In order to make toll collector, read-write machine, automatic fare collector and computer work together, we use VC++ to program the functions which operate the SLE4442 card and AT45D041 card. And we generate them as dynamic link libary (DLL) to be called by VB. Through communicating with RS232 and RS485, the hardware can be connected concordantly.
