摘要
随着技术与经济的发展,在电脑前久坐办公已成为工作常态,由此引发的健康问题层出不穷。设计一种久坐提醒器,该提醒器利用超声波和定时器检测用户处于坐姿的连续时间;当久坐时间超过预先定义的门限时,将自动进行声音报警;久坐时间门限可以依据个人情况进行调整,久坐时间和调整状态通过LCD显示屏幕观察。久坐提醒器为久坐族提供了方便的健康守护方案。
With the development of technology and economy,sitting in front of the computer for a long time has become a common working condition,and the health problems caused by sitting for a long time are also emerging in an endless stream.This paper designs an automatic reminder system for sitting for a long time.The system uses ultrasound and timer to detect the continuous time of the user sitting on the seat.When the sitting time exceeds the pre-defined threshold,the system will automatically alarm the sound.The system' s sitting time threshold can be adjusted by keyboard according to the specific situation of the individual,and the sitting time and the adjusting state can be observed by LCD display screen.The system provides a convenient health care program for the sedentary people.
