Problems solved by technology

However, when the pressure on the sole of the foot is excessively distributed on the inside, it is easy to cause the foot to turn outward; otherwise, it is easy to cause the foot to rotate inwardly, and at the same time, the internal rotation or outward turn of the foot also drives the internal rotation or outward turn of the knee, which is further controlled by the calf muscles. Foot pronation or valgus forms a vicious cycle. Long-term foot valgus or valgus can easily lead to plantar fasciitis, ankle joint injury, calf muscle involvement, etc. In addition, foot valgus or valgus also drives knee inversion Rotation or eversion greatly reduces the safety during exercise

Embodiment 1

[0069] Such as figure 1 As shown, the present invention provides a method for analyzing the state of motion, which includes a foot pad having at least two sensors symmetrical to the center line in the horizontal direction. The analysis method specifically includes:

[0070] Step S110, in the walking state, obtain the distance between each sensor and the center line, and the current pressure value of each sensor;

[0071] Step S120, calculating the pressure ratio on the left and right sides of the foot pad according to the pressure values ​​of the left and right symmetrical sensors;

[0072] Step S130, judging the current state of the foot according to the pressure ratio combined with a standard threshold; further, in the state where the pressure ratio is greater than the standard threshold, it is judged that the current foot is in an eversion state;

[0073] In the state where the pressure ratio is less than the standard threshold, it is judged that the current foot is in a s...

Embodiment 2

[0094] The first embodiment above provides a motion state analysis method for the user to know the gait analysis in the walking state, but the above analysis method cannot know that the user is in the jogging state, and thus cannot provide analysis and guidance for the jogging state.

[0095] Such as figure 2 Shown, the present invention provides a kind of motion state analysis method, specifically comprises,

[0096] Step S210, in the walking state, obtain the distance between each sensor and the center line, and the current pressure value of each sensor;

[0097] Step S220, calculating the pressure ratio on the left and right sides of the foot pad according to the pressure values ​​of the left and right symmetrical sensors;

[0098] Step S230, judging the current state of the foot according to the pressure ratio combined with a standard threshold; further, in the state where the pressure ratio is greater than the standard threshold, it is judged that the current foot is in...

Embodiment 3

[0134] On the other hand, if image 3 Shown, the present invention provides a kind of motion state analysis system again, wherein: also include:

[0135] The collection unit is formed in a foot pad, and the collection unit includes at least two sensors. The sensors are symmetrically arranged along the horizontal direction with the center line of the foot pad, and the distance between each sensor and the center line is obtained in walking mode. distance, and the current pressure value of each sensor;

[0136] A calculation unit, which calculates the pressure ratio between the left and right sides of the foot pad according to the pressure values ​​of the left and right symmetrical sensors;

[0137] A judging unit that combines the pressure ratio with a standard threshold to form a judging result output that matches the current foot state;

[0138]Wherein, the pressure ratio Q is:

[0139]

[0140] In the formula 1,

[0141] Y: It is the cumulative sum of the pressure valu...

Abstract

According to the embodiment, the invention relates to a detection technology, and in particular to a sports state analysis method and a sports state analysis system. A foot pad which is provided with at least two sensors which are bilaterally symmetrical about a center line in a horizontal direction is used in the sports state analysis method, and the analysis method comprises the following steps: under a walking state, acquiring distance of each sensor away from the center line as well as a pressure value on each sensor; calculating the ratio of pressure at the left side to pressure at the right side of the foot pad in accordance with the pressure values of the bilaterally symmetrical sensors; and judging a current foot state in accordance with the pressure ratio in combination with a standard threshold, and outputting a guidance tip matched with the current foot state under the state that the pressure values are not equal to the standard threshold. With the application of the analysis method and the analysis system, the foot state of a sportsman can be accurately acquired and correction guidance can be offered to the sportsman, so that sports safety is enhanced.

Description

technical field [0001] Embodiments of the present invention relate to detection technologies, and in particular to a motion state analysis method and system. Background technique [0002] Jogging exercise is the most commonly used physical exercise method. More and more residents exercise their cardiopulmonary function, bones, etc. through jogging. During jogging, before the feet hit the ground, the knees and soles buffer the huge pressure of the body at the same time, and the inner side of the heel is under pressure when the heel hits the ground. At this time, the outer side of the foot is relatively "flexible" (and the forefoot, reorganization can freely choose the landing position) ; When the midfoot and forefoot touch the ground, the outer side is under pressure; the moment the foot is pushed off the ground again, the foot is adjusted to a stable state, and the hip joints, knee joints, and ankle joints become stable again. However, when the pressure on the sole of the f...
