仿人型假肢脚趾按压信号识别的原理与实现

针对利用脚趾按压信号识别的原理来实现控制仿人型假肢运动的问题,构建了一种脚趾按压信号识别系统的基本结构,介绍了该系统的工作原理,并阐述了由脚趾按压时间长短而产生指令编码的方法;利用上位机应用程序结合MP150多导生理记录仪对脚趾按压信号检测系统的功能进行了实现。实验表明:所用的方法可以以很高的准确率检测脚趾按压信号并提取指令编码,达到了准确控制假肢运动的目的。

Principle and Implementation of Toe Pressure Signal Recognition for Humanoid Type Prosthetic

Aiming at realizing the type prosthetic movement control problem to use the principle of toe pressure signal recognition , the basic structure of a toe pressure signal recognition system was built , the basic principles of the toe pressure signal recognition sys-tem was introduced , the instruction and encoding method by the toes on the length of time were stated , the function of the toes on signal detection system was realized by using the PC application combined with MP 150 guide more physiological recorder .Experimental results show that this method can be used to detect toe pressure signals at high accuracy and to extract the instruction code , the purpose of the accurate control prosthetic limbs movement is achieved .
