摘要
介绍了一种预付费燃气智能管理系统的软硬件设计和具体实现。IC卡是目前应用较为广泛的应用于电子票据的一种智能卡。系统采用了逻辑加密存储卡SLE4442作为传递信息的媒介,通过卡表管理系统将用户的购气等信息写入卡中,然后通过PIC16F877单片机作为控制核心,读取卡内信息并根据该信息来智能控制燃气阀门。该系统只要稍加修改就可以应用于各种小额的收费管理系统中。
This paper introduces the software and hardware design and realization of an intellectual gas-prepaying management system.IC card is a popular intellectual card nowadays which do as a electronic bill.The system adopts IC card SLE4442 which has logic encrpytion as the information storage medium.This system write user＇s gas information into the card through the management system,and then adopt MCU PIC16F877 to read the information from the card and control the gas valve.The system can be applied in other kinds of small charge management system.
