摘要

针对现行LED信息屏系统便携性及成本的不足，设计了集信息编辑、处理与发送功能为一体的手持控制终端，并结合设计的具有信息接收与显示功能的显示终端，获得了LED屏信息在线修改系统。手持控制终端和显示终端以微处理器为核心，二者之间利用控制终端的矩阵键盘进行信息编辑并通过各自的无线模块进行连接和数据传输。实际测验表明：该系统能够实现一个手持控制终端对多个显示终端工况下的LED屏文本信息实时在线修改。

Abstract

In view of the poor portability and high cost of the current information screen system

the LED information online modification system is designed. This system includes a portable control terminal with the function of information editing

processing and transmission

and display terminals designed with the function of the information receiving and displaying. The core of the portable control terminal and display terminals is microprocessor. The control terminal uses matrix keyboard to realize information editing and communicates with the display terminals with the help of wireless modules equipped by them. The practical test show that this system can realize the function that one control terminal modifies multiple LED display terminals' text information online in real time.
