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 ter-minal with the function of information editing,processing and transmission,and display terminals de-signed 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.关键词
