摘　　要：以单片机为主控芯片,利用超声波测距原理,测出使用者下巴与桌面的距离,当距离小于设定值时启动声光报警。通过光敏电阻采集光线强度信息,根据等级区分光线,设定蜂鸣器和LED灯在光线不足时声光报警。通过定时器进行计时,当系统运行时间达到45分钟时开始报警,以提醒视力保护器的佩戴者注意休息。利用液晶显示模块直观显示距离、光强和学习时间,方便佩戴者使用。With the Single-Chip Microcomputer as the main control chip,the distance between the user's chin and the desktop is measured by using the ultrasonic distance measuring principle.When the distance is less than the set value,the audible and visual alarm will be activated.It collects the light intensity information through the photosensitive resistor,distinguishes the light according to the grade,and sets the buzzer and LED lamp to give an audible and visual alarm when the light is insufficient.The timer is used for timing.When the system runs for 45 minutes,the alarm will be started to remind the wearer of the vision protector to pay attention to rest.The LCD module is used to visually display the distance,light intensity and learning time for the convenience of the wearer.
