基于非接触式IC卡的高速公路收费系统设计

Design of Collection System of Highway Based on Unconnect Card

分析了当前高速公路收费系统的现状,指出了其存在的不足和缺陷,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;该收费系统模拟了西安至潼关的高速公路收费,实验证明该系统具有收费效率高,放行速度快,安全性高等特点。

Analyse the status of the charge collection system of the motorways and indicate its demerits. Introduces core of AVR single chip ATmega128, Use unconnect card collection system of highway, Given hardware design, Compile collection software based on data- base and VB. Achieve communication with epigyny computer. Lastly analyse IC card collection safety. It simulate collection from Xi＇an to Tongguan. Experiment attest high efficiency, rapidness and safety.
