一种视力保护装置的设计

Design of A Vision Protection Device

本系统包含三部分,距离光强检测器、坐姿矫正徽章以及智能手机.距离光强检测器能测量使用者用眼距离和光线强弱,坐姿矫正徽章可判断使用者是否出现驼背、高低肩等不良坐姿.二者均可将检测结果发送给智能手机,由手机应用程序判断使用者用眼及坐姿是否合理.本装置采用3.7 V可充电锂电池供电,使用方便,操作简单,是一款低功耗的健康电子产品,适合在青少年中推广.

This system consists of three parts, a sitting correction badge, a distance light detector and a smart phone. The distance light intensity detector takes STC12LE5A60S2 single chip microcomputer（SCM） as core, which includes an ultrasonic distance measurement module, a photoresistance module, a vibrator reminder module, a Bluetooth module and a power module. The sitting posture correction badge takes STM32F030 SCM as the main control center, which includes a gyroscope module, a vibrator reminder module, a Bluetooth module and a power module. The distance light detector can measure the distance from it to the user＇s eyes and the environment light intensity. The sitting posture correction badge can determine whether the user has hump, high and low shoulder or other bad sitting. Both of them can send the test results to the smart phone, the smart phone application can determine whether the distance from the detector to the user＇s eyes, the environment light intensity and the sitting posture are reasonable. This device uses 3.7V rechargeable lithium battery, it takes the advantage of easy to use, simple operation, it is a low-power health electronic product, is suitable for young people.
