基于单片机的视标投影仪设计

Design of Visual Target Projector Based on Microcontroller

阐述一种用于视力检查的视标投影仪设计,该系统使用红外遥控器发出操作指令,采用单片机作为控制芯片控制步进电机的转动,带动视标盘和遮板盘,实现数百种视标的组合。操作者可以根据检查习惯和常用场景,设置用户个性化程序检查模式,提高检查效率。

This paper describes the design of a visual aid projector for visual inspection.The system uses an infrared remote control to issue operating instructions,and uses a microcontroller as the control chip to control the rotation of the stepper motor,driving the visual aid disc and the shield disc to achieve the combination of hundreds of visual aids.Operators can set personalized program inspection modes for users based on inspection habits and common scenarios to improve inspection efficiency.
