摘要
从智能交通系统(ITS)信息显示服务子系统的需求出发,通过分析LED可变情报板与一般LED室内、室外显示屏的区别,阐述了LED可变情报板的特点,提出了LED可变情报板控制器的功能要求,并利用ARM7TDMI-S系列的LPC2210-PACK微处理器设计了一款LED可变情报板嵌入式控制器。
Based on the requirements of ITS Information Display Subsystem, this paper analyzes the differences between LED CMS （Changing Message Sign） and general indoor/outdoor LED Display Board, and states the characteristics and the functional requirements of LED CMS. This paper also shows a design of embedded LED CMS controller based on LPC2210-PACK processor of ARM7TDMI-S series.
