摘要
传统数字化视力检查仪的遥控器系统设计,存在按键操作复杂,可视化程度低等缺点,其原因主要采用键盘加红外构建遥控控制系统,在按键上印制简单图形显示对应的视标。文章提出一种无线智能遥控显示系统的设计方案,采用LCM液晶显示模块设计显示系统,选择AVR单片机为微控制器,通过ICC AVR语言编写控制程序,对液晶显示指令时序进行控制,从而达到按键响应和液晶提示协同工作,增加了人机交互的便利性和生动性,降低医生控制的复杂度,使视力检查更加灵活,简便。
Traditional digital visual inspection of the instrument remote control system design is complex button operation. low level of visual and so on. The main reason is adopting a keyboard plus infrared remote control system to build, in the print button on a simple graphical display, as the corresponding standard. In this paper, it is a wireless remote display system of intelligent design, using LCM display module design Display System, choosing the single-chip AVR as the microcontroller, using ICC AVR to design the control procedures, controling LCD timing of the command to achieve prompt response work together between the button and the liquid crystal. It increases the human- computer interaction and convenience of lively, reduce the complexity of the control of doctors, make the visual inspection more flexible and simple.
