Step counting method and step counting device

Abstract

The invention provides a step counting method and a step counting device. The method comprises the following steps of (a) acquiring three single-axis accelerated speed signals with predetermined lengths from the triaxial output of a triaxial accelerated speed sensor worn by a runner; (b) carrying out high-pass filtering on each single-axis accelerated speed signal; (c) detecting the fundamental frequency of each single-axis accelerated speed signal subjected to high-pass filtering; (d) setting a low-pass or band-pass filter by utilizing the fundamental frequency obtained by each fundamental frequency detection step, and carrying out the low-pass or band-pass filtering on the corresponding single-axis accelerated speed signal subjected to high-flux filtering; (e) acquiring an accelerated speed signal extreme point from each single-axis accelerated speed signal subjected to the low-pass or band-pass filtering, and removing an interference extreme point; (f) counting the number of the accelerated speed signal extreme points after the interference extreme points are removed; and (g) determining the accumulated step number of the runner. By adopting the method, the steps can be precisely counted.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a step counting method and device. Background technique [0002] A pedometer is a device that can count the number of steps its wearer walks or runs (hereinafter referred to as walking and running). As people pay more and more attention to their health conditions, pedometers have become an auxiliary tool for quantitatively formulating exercise programs and have been widely used. [0003] At present, pedometers are mainly divided into two types: mechanical pedometers and electronic pedometers. The mechanical pedometer uses the vibration of the internal reed or elastic ball of the pedometer to generate electronic pulses when the wearer walks and runs, and counts the number of these electronic pulses through the internal processor to realize the step counting function. Mechanical pedometers are less expensive, but less accurate and less sensitive. Electronic pedometers generally o...

Problems solved by technology

The disadvantage of these pedometer step counting methods is that directly using the peak value of the oscillating acceleration signal to determine the number of steps taken will lead to poor step counting accuracy, which will affect the execution of the pedometer wearer's exercise program
