摘要 目的:设计一种能够实时监测眼睛与书本之间距离、分析用户用眼习惯并提醒用户注意用眼距离的智能护眼测距眼镜。方法:采用STC89C51单片机作为系统主控单元,通过超声波测距模块测量用户眼睛与书本之间的距离,并通过蓝牙串口模块将数据发送至手机App。其中测距软件部分采用C语言编程,App的开发采用Android Studio IDE开发环境,将Java语言作为主要编程语言。结果:该眼镜在使用过程中稳定性良好、距离测试准确且提醒及时,能达到帮助矫正用眼习惯、降低近视风险的效果。结论:该眼镜功能设计合理,在满足人性化需求的同时能够更好地防止近视的发生,有一定的实用价值。 Objective To design a new type of intelligent eyeglasses to monitor the reading distance,analyze the habit of using eyes and remind the user of the reading distance.Methods The STC89C51 microcontroller was used as the main control device.The data on the distance between the user's eyes and the book was measured by the ultrasonic ranging module attached to the eyeglasses,and then sent to the cellphone App via Bluetooth module.The distance measurement software was programmed with C language,and the App was developed with Android Studio IDE and Java language.Results The eyeglasses developed gained high stability,measurement accuracy and timeliness for alert,and thus could be applied to correcting the habit for using eyes and reducing the risks for myopia.Conclusion The eyeglasses developed gives considerations on rational design,ergonomics requirements and myopia prevention,and thus is worthy promoting practically.
