摘要
据资料显示当前我国近视眼的发病率居世界第二,其中绝大多数是青少年。目前市场上的一些台灯只能实现单一的照明功能,姿势检测的相关产品功能也单一无法实现多个功能的集成化和自动化。基于此问题,本课题设计一款智能护眼灯,所涉及的智能护眼台灯具备学习姿态检测和校正提醒功能、学习时间检测提醒功能和光亮调节功能等。本文以C8051F340单片机作为主控制芯片,以光敏二极管模块经A/D转换后以测得环境的亮度值,通过PWM的方式调节LED的亮度,以超声测距模块来进行距离的测量,设计出一款具有自动调节光亮,坐姿矫正等功能于一体的智能化LED台灯。
According to the data show that the incidence of current our country myopia rate ranked second in the world, most of them are young people. At present, some lamps only on the market to achieve single lighting function, position detection of related products single function can not be achieved automatic multiple function integration. For this, the project is to design a smart eye protection lamp, the intelligent eye protection desk lamp with learning attitude detection and correction to remind function, function of learning time detection to remind function, light regulation function.This paper takes C8051F340 as the main control chip, in photosensitive diode module by the brightness of A/D conversion to the measured value of the environment, adjust the brightness of LED by way of PWM, to measure the distance by ultrasonic ranging module is designed with a brightness automatic adjustment, timing alarm by buzzer, posture correction function and in one of the only LED lamp.
