无线感应供电的旋转LED动态显示屏设计

Design of Rotating LED Dynamic Display with Wireless Induction Power Supply

针对传统点阵显示屏宣传展示效果普通、尺寸大、成本高的问题,设计了一套无线感应供电的旋转LED动态显示屏系统。介绍了旋转动态显示屏系统的设计方案和控制原理,并进行实物电路和软件设计调试,完成了旋转动态显示屏样机的制作和运行。实际运行表明,相对于传统LED显示装置只要少量LED实现显示,具有成本低、控制方便、展示效果好的优点,具有良好的推广价值。

Aiming at the problems of ordinary publicity and display effect,large size and high cost of traditional dot matrix display,a set of rotating LED dynamic display system powered by wireless induction is designed.This paper introduces the design scheme and control principle of the rotating dynamic display system,designs and debugs the physical circuit and software,and completes the manufacture and operation of the rotating dynamic display prototype.The actual operation shows that,compared with the traditional LED display device,only a small number of LEDs are needed to realize the display,which has the advantages of low cost,convenient control and good display effect,and has good popularization value.
