摘　　要：随着老龄化社会的严重加剧,老人将会在未来越来越多,因此如何设计一款老人摔倒检测系统是非常重要的,目前国内外的监控方式有以下两种:第一种是老人摔倒后处在一种清醒状态下,按下报警按钮,但不适合老人晕倒状态;第二种是视频监控装置,但是这种装置也有很大的局限性。针对上述存在的问题,设计了一个便于携带的摔倒检测定位系统。本系统由STM32的核心板、ADXL345加速度传感器、GSM、GPS模块、蜂鸣器的警报和电源构成。当ADXL345加速度感测到倾斜的变化时,信号发送到STM32。如果不能在15 s内起立关闭,将通过GSM向手机告知监护人老人摔倒的位置。具有实时性强,使用方便的特点,具有良好的市场前景和推广价值。Much worse as the aging society,the old man will be more and more in the future,so how to design an old man fall detection system is very important,at home and abroad of the monitoring method has the fol-lowing two kinds:the first is to the old man in a state of alert after the old man fell down,press the alarm but-ton,but is not suitable for the old man fainted state;The second is the video surveillance device,but this de-vice also has great limitations.In view of the above problems,a portable fall detection and positioning system is designed.This system is composed of STM32 core board,ADXL345 acceleration sensor,GSM,GPS mod-ule,alarm of buzzer and power supply.When the ADXL345 acceleration senses the tilt change,the signal is sent to STM32.If the elderly cannot stand up within 15 seconds,the guardian will be informed of the location of the fall via GSM.With the characteristics of strong real-time,easy to use,has a good market prospect and promotion value.
