Cheng Ya Highway Information Management System

The working principles of the "ChengDu-YaAn freeway display system"and the design realization of its hardware and software are discussed in detail. In this system Mcs5l microcontroller technology, Visual C+ +6.0 Programming, isp technology ,SQLSever DataBase technology, ODBC technology etc. ,are adopted. Of this article, chapter one studies the current situation of ChengDu-YaAn freeway display system , and the operating environment and development of the system; Chapter Two discusses the overall functions of the system; Chapter Three and Four demonstrate the design and realization of the system抯 hardware and software; Chapter Five also discusses the adjustment and operation of the system.This research combines the design method and realization, and considers the design method to be more important. It can not only be used in the development of intelligent detecting and control systems but also for research's reference.
