随着老龄化的加速,老人健康的问题越来越得到社会的关注,其中,跌倒是危害老人健康的重要原因。本文采用Arduino硬件平台、JY901加速度传感器模块和SIM900A串口GPRS模块构建了一种跌倒监测系统。该系统通过串口采集加速度传感器模块的运动数据,送到单片机进行跌倒检测,GPRS模块将跌倒状态发到服务器远端。该系统成本较低,能较精确地实现跌倒检测。
With the acceleration of aging problem, people pay more attention to the health problem of the elders. The falling down of the elders is an important cause for harming their health. This paper proposes a falling detection system by using Arduino platform, JY901 accelerometer and SIM900A GRRS module. The motion data sensed by aecelerometer is sent to MCU for fall detection. The detecting result is also sent to server by GPRS module. This system has the advantage of low cost, and it can detect the fall aecur: tety.
