MMA7260加速传感器在老年人跌倒检测系统中的应用

Application of the Elderly Fall-Down Detection System Based on MMA7260 Acceleration Sensor

摘要: 针对老年人摔倒现象，将MMA7260加速度传感器运用到老年人跌倒检测系统中，通过步态特征提取方案，经数学运算得出相应的位移、速度值，从而实现传感器网络节点的信息采集与数据分析工作，将老人的身体状况实时告知监护人。

Abstract: MMA7260 acceleration sensor is used in the elderly fall-down detection system for the elderly fall- down phenomenon. The sensor’s network nodes information collection and data analysis will be realized by the step’s features extracting and the corresponding displacement as well as velocity operating. The elderly physical condition will be told to the guardian in time.
