摘要
提出了以AVR单片机ATmega128为核心处理器,采用非接触式IC卡技术的高速公路收费管理系统。给出了系统的硬件设计,同时基于数据库技术并采用VB编写了收费系统软件管理系统,并实现了与上位机通讯,最后分析了IC卡收费系统的安全性措施。
As the core of AVR single-chip computer ATmega128, the unconnect card collection system of highway is introduced, and the hardware design are also given. The collection software based on data-base and VB are complied to achieve communication with upper computer. Lastly the IC card collection safety measurements are analyzed.
