摘要
基于单片机的智能叫醒眼罩的设计是在通过对人类睡眠时眼球转速检测的基础上,判断睡眠程度的深浅,就可以调整叫醒时间,在最大程度上保证睡眠的质量。该装置在眼罩中嵌入箔式电阻应变片,通过单片机和放大电路采集人眼转动时的应力变化。该系统原理简单,采用嵌入式安装,做到了最大程度的简化。
By detecting the speed of eyeballs＇ movement,this design can judge the degree of sleeping,so as to adjust the waking-up time to a better extent assuring sleeping quality.The system adopts the embedded foil type resistance strain piece,single-chip microcomputer and amplifying circuit to collect the stress variations when eyeballs are rolling.It makes the maximum simplified installation and achieves a comfortable effect.
