摘要
设计了一个基于单片机控制的旋转LED显示屏。显示屏在直流电机的带动下利用视觉残留原理显示内容,并采用无线供电的方式,利用电磁感应原理给控制主板供电,并在系统装有时钟芯片,通过红外遥控控制文字、时间及日期的显示,实现了显示屏以多样化的方式显示各种信息的功能。经测试,该显示屏具有运行可靠、节能、成本低、使用方便的特点。
A rotary LED display based on single-chip control was designed. The display screen uses the principle of visual residue display driven by a DC motor, and using wireless power, using the principle of electromagnetic induction to supply power to the control board, and in the system is equipped with a clock chip, infrared remote control of text,time and date display, enables the display to display various information in a variety of ways. After testing, the display has the characteristics of reliable operation, energy saving, low cost and convenient use.
