摘要
本文从LED可变情报板(LED CMS)系统在智能交通系统(ITS)中的重要作用出发,分析了LED可变情报板系统的功能特点,介绍了LED可变情报板系统的整体设计方案,以及在设计中遇到的难点和关键技术,最后利用SANSUNG的S3C44B0X处理器和ALTERA Cyclone的FPGA器件,设计了基于Uclinux操作系统的可变情报板系统嵌入式控制器。
This paper begins with the importance of LED CMS system in the ITS, then analyzes the functional characteristics of the LED CMS system, introduces the entire design project of the CMS system and the difficulties ,the key technology in the process of design, At last ,we designed LED CMS system embedded controller based on uclinux Operating System.with SAMSUNG S3C44BOX processor and Altera cyclone＇s FPGA.
