IC 卡消费系统的上位机程序设计 IC 卡消费系统的上位机程序设计 摘 要 随着人们生活水平的提高， 人们对生活中的便利性提出了更高的要求， 希望 有一种简单、安全、实用的方式。该设计是在有线通信的基础上，构建起 PC 机 和单片机的通信， PC 机通过串口向单片机发送指令，单片机识别正确后，单片 机向消费系统主界面发送 IC 卡数据， 进而实现 IC 卡的读取、 充值与初始化。 上 位机部分，通过调用 MSComm 控件接收数据、处理数据和显示数据。本设计的 重点是剖析串口通信的实现与消费系统的运行，探讨软件的设计方案。 关键词 IC 卡； MSComm 控件； 串口通信 I IC 卡消费系统的上位机程序设计 THE PROGRAM DESIGN OF UPPER COMPUTER BELONGING TO IC CARDS CONSUMPTION SYSTEMS ABSTRACT With the improvement of peoples living standard, people put forward a higher convenience requirement in daily lives, they hope a simple, safe and practical way to replace the cash and ticket transaction today. The design is based on the wirecommunication, building up a communication between PC and MCU, the PC send an instruction to MCU via serial port, after MCU identifies the instruction correctly, the MCU sends the IC card data to Main Interface of the consumption system to realize the reading, recharging and initiating. The upper computer part receives, processes andshows data by invoking MSComm control widget. The key point of this design is to analysis the relationship between the realization of serial port communication and the operation of the consumption system, and to discuss the software design scheme.
