摘要: 设计了一种基于蓝牙和3轴电子陀螺仪的运动状态监测系统设计方案。该方案以 MEGA2560为开发板,Arduino IDE为开发平台,可以在安卓设备上通过蓝牙接收到人体运动状态。该系统通过检测人体三轴与地磁三轴的夹角变换来判断人体的运动状态。当人体跌倒时,人体三轴会和地磁三轴产生偏角,当偏角达到设定的角度时,蓝牙模块即会发出信号,此时 Android 设备就会接收到摔倒的信息。该系统还具有低功耗、体积小的特点。

Abstract: The paper presents a design of motion detection system based on Bluetooth and 3 axis electronic gyroscope. During the design, MEGA2560 is used as the development board and Arduino IDE the development platform. The system receives motion state information of human body via Bluetooth embedded in android equipment. The system analyzes the motion state by measuring the angle between the 3 axis of the human body and the 3 axis of the geomagnetic field. The angle changes as human body fall. When the angle reaches threshold, the Bluetooth module will immediately send a signal to the android equipment. The system is of low power consumption and small size.

Key words: 3 axis gyroscope, motion detection system, bluetooth
