摘要

针对大多数现有的足底压力数据采集系统价格昂贵

且容易受到场地和环境的限制的问题

设计了一种基于足底压力传感器的无线式可穿戴人体步态分析系统。采用由8只压阻式传感器组成的压力鞋垫来准确地获得足底压力信号的动态响应。通过信号调理电路对信号进行滤波并将电阻变化信号转换为电压变化信号

通过单片机进行A/D转换

使用WiFi模块来对数据进行收发。为了验证系统的可靠性和准确性

对行走、跑步和下蹲三种运动状态的数据进行了采集和分析。实验结果表明:设计的系统可以有效地捕捉足底不同部位的压力变化

并用于进行人体步态分析。

Abstract

Aiming at the problem that most of existing plantar pressure data acquisition systems are expensive and subjected to site and environment constraints

a kind of wearable human gait analysis system based on plantar pressure sensor is designed. Pressure insoles with eight piezoresistive sensors are used to obtain the dynamic response of pressure signals. A resistance-voltage conversion module is designed to convert resistance signal into voltage signal. The data is transceived using WiFi module. To verify the reliability and accuracy of the system

the data of walking

running and squatting are collected and analyzed. The experimental results show that the pressure sensing system can effectively capture the pressure changes on different parts of foot for human gait analysis.
