摘　　要：为了减少因跌倒后救治不及时给老人身心带来的伤害,文中提出了一种基于Android手机多传感器的跌倒检测方法。利用三轴加速度传感器和气压计,检测跌倒时加速度和海拔高度的变化特征,实现跌倒判定。同时考虑到不同体格特征的人群身高、体重、年龄等的差异,文中引入了合理的阈值调节机制。并且,文中基于此方法在Android智能手机平台上设计实现了跌倒检测系统,实验结果表明该系统的检测准确率86%。Aiming at avoiding the sever injury caused by elders falling down without prompt treatment, this paper develops a method of falling-down detection system based on multisensor in Android phones. This system utilizes three-axis accelerometer and barometer to detect the changes of acceleration and altitude to determine whether a falling down accident has occurred.Taking it into consideration that different individuals differ in bodily features like height, weight and age, This paper introduces a reasonable threshold adjusted mechanism. It also reveals that the system has been implemented on the Android smart phone platform with experimental results＇ showing that the detection accuracy of the system is 86%.
