Embodiment Construction

[0037] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0038] like figure 1 Shown is the system flowchart of a kind of gait counting method of the present invention, specifically comprises:

[0039] S1. The acceleration sensor collects the acceleration signal generated when the wearer moves according to the set frequency;

[0040] S2. Sampling and filtering the acceleration signal counted by the acceleration sensor, restoring the acceleration signal generated by the acceleration sensor and the eigenvalues ​​in the time domain waveform;

[0041] S3. Generate a first dynamic threshold parameter, a second dynamic threshold parameter and a dynamic time parameter according to the acceleration signal obtained in step S2 within the set time;

[0042] S4. Comparing the acceleration signal collected this time with the first dynamic threshold parameter, the second dynamic threshold parameter and the dynam...

Abstract

The invention discloses a gait counting method and a gait counter. The gait counter can be worn on a wrist or other parts of a body and is used for precisely counting different kinds of gaits of a wearer. The gait counting method comprises the following steps: analyzing an output signal of an acceleration sensor so as to generate two groups of dynamic threshold parameters and a group of dynamic time parameters; when an acceleration output signal change value is greater than a first threshold parameter and spans downwards across a second threshold parameter, performing gait counting analog; comparing the time and corresponding dynamic time parameters in two times of gait counting analog so as to confirm whether next detection is performed or not; performing wrist belt type gait counting characteristic comparison and judging; subsequently judging whether the gait counting analog meets specific counting rule parameters; judging whether the gait counting analog meets corresponding gait rule parameters so as to confirm whether the corresponding gaits need to be counted. By adopting the gait counting method and the gait counter, the wearer can wear the gait counter on the wrist or the other parts of the body to precisely count the different kinds of gaits.

Description

technical field [0001] The invention relates to the technical field of consumer application electronics, in particular to a gait step counting method capable of counting the number of steps of a user and a design of a pedometer. Background technique [0002] The pedometer detects the acceleration in the vertical direction of the pedestrian through the acceleration sensor, and counts the number of steps or body movements based on the change of the detected value, and displays the counted number of steps numerically. In recent years, pedometers can not only measure the number of steps, but also detect different gaits, such as walking status and running status. [0003] However, in the actual exercise process, walking and jogging are the aerobic exercise methods chosen by many people. However, the leisurely walking process is often slow walking or even pacing, that is, there is a moving state like two feet touching the ground at the same time. The way of movement will be obvio...
