摘 要:结合单片机技术和移动通信技术设计基于跌倒检测的老人看护系统,通过陀螺仪实时采集老人身体姿态,经单片机分析并判断是否发生跌倒。若符合跌倒条件,实现蜂鸣器报警现场求救,以及发送老人定位信息短信进行救援呼叫的双重功能,并设定跌倒后求助短信发送延迟时间,可用手动按键方式关闭报警解除误判。旨在降低跌倒给老年人带来的二次伤害,减少经济损失,提高老年人的晚年生活品质。

Abstract: The elderly care system based on fall detection is designed by combining the Single-Chip Microcomputer technology and mobile communication technology. The body posture of the elderly is collected in real time through the gyroscope, analyze and determine whether a fall has occurred through a Single-Chip Microcomputer. If the conditions for falling are met, the dual functions of buzzer alarm for on-site rescue and sending elderly positioning information SMS for rescue call can be achieved. The delay time for sending help SMS after falling can be set, and the alarm can be manually turned off to resolve misjudgment. The aim is to reduce secondary injuries caused by falls to the elderly, reduce economic losses, and improve the quality of life of the elderly in their later years.
Keywords: STM32 MCU; gyro posture acquisition; intelligent care

當前社会老龄化现象日趋严重,人口老龄化比例逐步上升,老人的身体健康和人身安全等问题成为亟待解决的问题,对老年人群体威胁最大的是因跌倒引发的意外伤害,跌倒既可能直接造成身体受伤或致残,也可能使老年人因畏惧跌倒而不敢进行正常活动,这都给老年人的生活造成了不良影响,可以说,跌倒已经成为威胁老年人健康和安全的最大隐患。
据卫生部门调查显示,65岁以上的高龄人口中,约22%男性与43%女性均有过跌倒经历。老年人因跌倒引发的意外伤害占意外伤害比例的78%,65岁及以上的老人发生跌倒的比例占20%~28%,其中,造成伤害的比例达高达70%,10%左右为严重伤害程度。跌倒后未及时救治会对老人造成一定程度的创伤,严重的甚至威胁到生命安全,给老人及其亲人带来沉重的负担,老年人的身体健康和日常生活也将会面临严峻的挑战。……
