Design of Human Motion State Monitoring Device Based on Wireless Motion Sensor Node

本文通过对无线运动传感器节点进行设计,制作了一种人体运动状态监测装置。首先采用STM32F103单片机设计一个无线运动传感器节点,再由温度传感器LMT70和姿态传感器MPU6050检测出温度信号和运动信息后反馈给STM32F103单片机进行分析和计算,得出准确的体表温度、运动距离与步数,接着ADS1292在采集到心电信号后通过增益放大和数模转换向STM单片机输出数字信号,最终蓝牙模块将人体的心电信号、运动信息和体温值在电脑上位机上显示出来。经过实际测试,体表温度、运动距离与步数的误差均控制在5%以内,说明该装置自适应良好,监测输出结果准确可靠。

This paper designs a human motion state monitoring device by designing wireless motion sensor node.Firstly,a wireless motion sensor node is designed by using STM32F103 single chip microcomputer,and then the temperature signal and motion information are detected by temperature sensor LMT70 and attitude sensor MPU6050 and fed back to STM32F103 single chip microcomputer for analysis and calculation,and the accurate body surface temperature,movement distance and step number are obtained.Then,the ADS1292 outputs the digital signal to the STM single chip microcomputer through gain amplification and digital-to-analog conversion after the ECG signal is collected.Finally,the Bluetooth module displays the ECG signal,motion information and body temperature on the computer.After the actual test,the errors of body surface temperature,movement distance and step number are controlled within 5%,which shows that the device has good adaptability and the monitoring output is accurate and reliable.
