摘要
根据人体步态分析的需求 ,我们设计并研制了一套体积小巧 ,功耗低 ,能实时测量 ,测量参数丰富 ,结果直观 ,人机界面友好的足底压力分布测量系统。系统的硬件包括由压力传感器阵列制成的鞋、信号调理单元、主电路单元三大部分。系统软件具有数据采集、文件管理、信号处理、步态特征参量提取及分析等多种功能。其图形丰富 ,操作简便 ,是一套人机界面友好的专用软件。此系统与三维运动子系统和三维测力台子系统可以共同组成一套完整的、功能齐全的人体步态分析系统。
A new system was described for foot pressure measurement and gait analysis. The system consisted mainly of a pair of specially made shoes, force sensors, data acquisition circuit, an interface and a microcomputer. The function of software included data acquisition, files management, signal processing and gait parameters abstraction, etc. The unit carried by subjects was portable and of low power. The system was easy to use and the measurement result easy to understand. Such a system, combined with the 3D kinematics analysis subsystem and force plates, formed an advanced gait analysis system.
