一种基于物联网技术的下肢运动实时监测系统设计与实现

A Monitoring System of Lower Limb Movement Based on Internet of Things

文章设计了一种实时获得下肢运动期间表面肌电信号、姿态传感器信号和足底压力信号的实时监测系统.系统包括用于信号采集的硬件系统和对应的APP应用两部分.信号采集的硬件系统可以对行走、跑步、高抬腿、原地踏步、站立和坐立等下肢运动期间的肌电信号、姿态传感信号和足底压力信号进行实时采集,采集的数据通过蓝牙协议传输给移动终端,移动终端APP应用可以实时监测出其运动类别.测试结果表明:系统对下肢运动实时监测有较高的准确率.

Combining sensor technology,a monitoring system of lower limb movement is designed.The system includes hardware system for signal acquisition and corresponding App application.The hardware system of signal acquisition can collect the EMG signal,posture sensing signal and plantar pressure signal of walking,running,high leg raising,standing,standing and other lower limb movements in real time.The collected data is transmitted to the mobile terminal through Bluetooth protocol,and the mobile terminal app application displays the movement category in real time.The simulation results show that the system has high accuracy in real-time monitoring of lower limb movement.
