Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that there are few studies on swimming monitoring in the prior art, and most of the existing swimming monitoring methods are based on the movement of the human trunk, the technology for judging different swimming styles and the number of strokes The method is not accurate enough, so a swimming monitoring method based on wrist position is proposed

Embodiment

[0043] This embodiment provides a swimming monitoring method, the monitoring method includes the acceleration sensor collecting the acceleration parameters of the swimmer in the three axes of X, Y, and Z, and then determining the obtained swimming style information (the average value of the motion data obtained by swimming monitoring and detection) Waveform after filtering figure 1 shown), wherein the method comprises the steps of:

[0044] S1) at t 0 -t 1 Acceleration values ​​x, y, z of the three axes of X, Y, and Z are collected within the ΔT period of time;

[0045] S2) Obtain the average value A of the angle value x-y in the ΔT period 0 , the

[0046] The average value of the included angle value x-z in the ΔT period is obtained as A 1 , the

[0047] S3) According to the calculation result A 0 、A 1 with threshold h xy0 、h xz0 、h xy1 、h xz1 Comparing the stroke prediction, when (A 0 >h xy0 )&&(A 1 >h xz0 ) or (A 0 xy1 )&&(A 1 xz1 ), then go to step S4...

Abstract

The invention belongs to the field of sport monitoring and relates to a method for monitoring swimming. A gravity sensor of a device of the invention determines different swimming strokes through average value filtering of X, Y and Z axial data, in combination with a judgment formula, and according to the shape and the numerical value of data result. Compared with the prior art, the gaps in swimming detection of sport detection devices are filled up; wearable devices can be addedincluded to add the function of present wearable devices; the method has great market economic value and prospect.

Description

technical field [0001] The invention belongs to the field of motion monitoring, and in particular relates to a swimming monitoring method. Background technique [0002] In recent years, because the motion sensor can record the motion state of the human body in real time, it is easy to carry and low in price, it has gradually become a research hotspot in recent years, such as pedometers, cycling meters, and sports watches equipped with sports devices that people often use recently. , mobile phones and other mobile devices can enable people to know their exercise status and physical condition at any time. The obtained physical condition data can provide timely feedback on the physical condition of the exerciser and can be used for follow-up health analysis; among many sports, swimming Because it has a certain exercise intensity, but it is different from ground equipment training, it is a very gentle exercise method. When swimming, people usually use the buoyancy of the water t...
