摘要
设计了一种基于单片机的老人跌倒检测装置,采用加速度、陀螺仪传感器采集原始信号。在进行数据融合时采用自适应互补滤波算法,从频域角度消除噪声。针对该装置设计了一种计算量小的跌倒检测算法,并且加入了GPS定位装置和GSM短信模块。实验证明该跌倒检测算法计算量小、误判率低,并且能够实现精准定位。
An elders fall detection device based on single chip microcomputer is designed in this paper. Accelerometer and gyro sensor are used to acquire the original signal. In the data fusion using adaptive complementary filtering algorithm,from the frequency domain to eliminate noise. A fall detection algorithm with small computation is designed,and the GPS positioning device and GSM SMS mental results show that the algoritlim has the advantages of low computational complexity,low false positive ra te, and accurate posit ioning.
