基于单片机的超声波视力保护器设计与研究

针对当前视力保护器装置存在的问题,本文采用小型超声波模块辅助监测距离、光敏电阻检测光强,以单片机为控制核心,采用同时可通过程序设定时间和报警参数,最后通过液晶显示屏来显示信息,为了满足使用者的需求,本设计还设计了在线修改原始参数的功能。经过测试,系统简单,测试精准,在青少年视力保护领域具有较好的应用价值。

In this paper,based on single chip microcomputer to achieve the design of an ultrasonic eyesight protection,the design is based on AT89C51 as the core,using small distance ultrasonic auxiliary monitoring module,photosensitive resistance testing light intensity,at the same time can be set by the program time and alarm parameters,and finally through the LCD to display the information,in order to meet the needs of users,this design also designs the function of modifying the original parameters online.The whole system is simple,practical,responsive and suitable for the protection of young people's vision.
