老人摔倒求救系统的设计

A emergency system design for old people fall

本文针对社会中的老人群体,从实际应用角度出发,提出了便携式摔倒求救器设计方法。该设计采用STM32单片机,外加二路倾角传感器检测老人摔倒信号,利用GPS技术定位老人位置,并控制GSM模块发送求救短信,并拨打求救电话。上位机APP可展开地图进行详细定位,实现具体定位地点鲜明准确。通过实验,该设计可实现老人独自在家或行走在外时,突发险情摔倒自动求救的功能,且具有较高的可靠性和稳定性。

This paper proposes a emergency system design for old people fall.The system consists of a STM32 MCU,a SW-520 D sensor and a GPS/GSM module.It can provide the function of detecting the fall signal,fixing the location of the fall old people,and sending a message for help.Meanwhile the mobile phone App can open a map fixing the location of the fall old people.Through the experiment,the system can implement an emergency function wherever an old people falling down alone,which has high reliability and stability.
