Embodiment Construction

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

[0038] Such as 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 dy...

Abstract

The invention discloses a gait step counting method and a pedometer. The pedometer can be worn on the wrist or other parts of the body, and can accurately count steps for different types of gaits of the wearer. The present invention produces two groups of dynamic threshold parameters and a group of dynamic time parameters by analyzing the output signal of the acceleration sensor; when the change value of the acceleration output signal is greater than the first threshold parameter and crosses the second threshold parameter downward The number of steps to be counted; compare the time between two proposed steps with the corresponding dynamic time parameters to determine whether to carry out the next detection; enter the wristband-type step counting feature comparison stage and make a judgment; then, judge the proposed Whether the step counting conforms to the specific counting rule parameter; judge whether it conforms to the corresponding gait rule parameter to determine whether to count the step for the corresponding gait. The implementation of the invention can enable the wearer to wear the pedometer on the wrist or other parts of the body to obtain accurate step counting in different stances.

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...
