基于九轴传感器的人体异常行为检测

Human Abnormal Behavior Detection Based on Nine-Axis Sensor

针对于我国老年化进程加快,老年人异常行为频繁发生等情况,基于传感器的人体异常行为检测成为当今社会研究热门方向。为了更加准确地进行检测,设计一种基于九轴传感器异常行为检测系统。该系统采用三轴加速度传感器,三轴陀螺仪传感器用于采集人体姿态的加速度和角速度值。三轴磁力计用于辅助定位。利用传感器采集心率、温度人体特征参数。用SIM900A模块GSM/GPRS进行地理信息采集和短信报警,将相应的地理位置、采集转换的参数发送给监护人,从而实现对异常行为的检测。

In view of the accelerated aging process and frequent occurrence of abnormal behaviors of the elderly in our country,detection of abnormal human behavior based on sensors has become a hot research direction in today's society.In order to detect more accurately,designs a kind of abnormal behavior detection system based on nine-axis sensor.The system uses a three-axis acceleration sensor,and a three-axis gyro scope sensor is used to collect acceleration and angular velocity values of human posture.The triaxle magnetometer is used for assisting po sitioning,uses sensors to collect human body characteristic parameters of heart rate and temperature.The SIM900A module GSM/GPRS is used for geographic information collection and short message alarm,and the corresponding geographic location and collection and conver sion parameters are sent to the guardian,thus realizes the detection of abnormal behaviors.
