specific Embodiment approach

[0029] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described below.

[0030] A step counting method, based on a three-axis acceleration sensor to collect acceleration signals when the human body is moving, is characterized in that the acceleration signals when the above-mentioned human body is moving are analyzed and detected, and the absolute value of the vector sum of the original data of the three axes is used as the basis Data, the basic data is processed by sliding average, and the sliding average is taken as the calculation data, and the fluctuation of the data value and the time parameter are used as the analysis object, and the characteristic points in the time waveform of the above physical quantities are periodically displayed, and the peak is used as the basis for judgment Step counting, from the trough to the peak and then to the trough is a complete step. When judging whether to count steps, add a time factor: when the in...

Abstract

The invention discloses a gait step counting method and a pedometer, which are based on a three-axis acceleration sensor to collect acceleration signals when the human body is moving, and are characterized in that the acceleration signals when the human body is moving are analyzed and detected, and the three-axis The absolute value of the vector sum of the original data is used as the basic data, and the basic data is processed as a sliding average, and the sliding average is taken as the calculation data, and the fluctuation of the data value and the time parameter are used as the analysis object. Types of gait for accurate step counting. It has the characteristics of clear logic, accurate step counting, and small amount of calculation, and is especially suitable for environments with very limited resources.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a step counting method and a pedometer capable of counting the steps of a user. Background technique [0002] The existing pedometer detects the acceleration of the pedestrian's up and down direction through the acceleration sensor, and counts the number of steps or body movement based on the change of the detected value. In the actual movement process, due to the complexity of the movement, the typical peak Judgment will be interfered by various factors, mainly including short-term fluctuation interference and small amplitude fluctuation interference. However, during fast movement, the normal waveform is similar to the waveform caused by the previous two interferences. Therefore, the difficulty of the algorithm is to effectively distinguish the disturbance from the normal fast motion waveform. As an existing technology, it is determined whether to step by detecting the acce...
