Abstract

The invention discloses a method for recognizing a human walking gait cycle with an electromyographic signal and relates to a method for measuring human limbs movements. The method for recognizing the human walking gait cycle with the electromyographic signal is characterized in that a utilized device comprises a singlechip, an electromyographic signal sensor and a three-point differential input electrocardio electrode based on a segmentation integral algorithm, wherein the electromyographic signal sensor records and processes the electromyographic signal collected by the electromyographic signal sensor to obtain a positive level unstable signal, then the singlechip transfers, moves and calculates an average filter by utilizing a peak-valley segmentation integral algorithm or a simplified algorithm of a peak-valley linear interpolation segmentation integral algorithm to obtain a human walking gait cycle, therefore, the method solves the problems of easy abrasion of a signal sensor of a human movement signal and zero drift of the electromyographic signal sensor and also overcomes the defects that the traditional gait cycle recognizing method is complex and has high equipment price and larger calculation amount. The method for recognizing the human walking gait cycle with the electromyographic signal only needs a single channel signal as an information source and improves the application universality because a plurality of muscles of a person can be selected.

Description

technical field

[0001] The technical scheme of the invention relates to a method for measuring the movement of human body limbs, specifically a method for identifying the walking gait cycle of a human body by using electromyographic signals. Background technique

[0002] After literature search, it is found that at present, video detection technology is mainly used for the recognition of gait cycle at home and abroad. CN101477618 The automatic extraction method of pedestrian gait cycle in the video discloses a method for automatically extracting the gait cycle characteristics of the pedestrian target in the video through a theory of frequency domain analysis, but in the evaluation of artificial limbs, walking aids and rehabilitation training Obtaining gait cycle information through these methods in the fields such as these makes the price of the equipment too high, and the calculation amount is relatively large. In 2006, He Lesheng and others published a paper "A Method for...
