In addition, the embodiment also constructs a method for preventing sports injury of the sports shoe for detecting wearing time and sports strength

Comprises a gravity sensor 1, a timer 2, a pressure sensor 3, a controller 5 and a control center 12.

The gravity sensor 1 is an ultrathin gravity sensor, and as shown in fig. 5 to 6, the gravity sensor includes a circuit board 101 and a top cover 106 which are bonded together, the circuit board 101 is specifically bonded and stacked on the top of the top cover 106, and an optical signal emitting chip 102, an optical signal receiving chip 103 and an optical signal receiving chip 104 are soldered on the circuit board 101. Three supporting

edges

109, 1010 and 1011 are sequentially arranged on the left side wall, the front side wall and the right side wall of the top cover 106. The top of the three supporting

edges

109, 1010 and 1011 surrounds the middle of the top cover 106 to form a square chamfer cavity 107, a steel column 105 is arranged in the square chamfer cavity 107, and three light guide grooves 108 are formed between the tops of the supporting

edges

109, 1010 and 1011 at intervals. Three circular arc shaped edges 1013, 1012, 1015 are arranged at the periphery of the three light guide grooves 108, between the supporting

edges

109, 1010, between the supporting

edges

1010, 1011, and between the supporting

edges

109, 1011, and at the bottom of the corresponding top cover 106. And is used to block the optical signal so that it does not pass through the gap formed between the steel post 105 and the bottom of the top cap 106. The supporting

edges

109, 1010, the supporting

edges

1010, 1011, the supporting

edges

109, 1011 and the left side wall, the right side wall, the rear side wall and the circular arc shaped edges 1013, 1012, 1015 of the top cover 106 respectively surround to form three cavities 1014 for accommodating the optical signal receiving chip 103, the optical signal receiving chip 104 and the optical signal transmitting chip 102 on the circuit board. When the ultrathin gravity sensor rotates, due to the action of gravity, the steel column 105 can shield or open different light guide grooves 108, so that the optical signal receiving chip 103 and the optical signal receiving chip 104 are in a light receiving state or a light non-receiving state, and the optical signal receiving chip 103 and the optical signal receiving chip 104 send different signals. The steel column 105 refracts the optical signal of the optical signal transmitting chip 102 to the optical signal receiving chip 103 and the optical signal receiving chip 104. When the optical signal receiving chip 103 receives the optical signal, the optical signal receiving chip 104 is turned on and connected to a line of an external application device to output a corresponding high level 1 or low level 0.

signal receiving chips

103 and 104 cannot receive optical signals, and the optical

signal receiving chips

103 and 104 are in a cut-off area, so that the corresponding output ends OUT1 and OUT2 of the circuit board 101 output low levels of 0 respectively. When the ultrathin gravity sensor rotates to 90 degrees, the steel column 105 shields the optical signal receiving chip 103, the steel column 105 refracts the optical signal emitted by the optical signal emitting chip 102 to the optical signal receiving chip 104, at this time, the output end OUT1 corresponding to the optical signal receiving chip 103 outputs a low level 0, and the output end OUT2 corresponding to the optical signal receiving chip 104 outputs a high level 1. When the ultra-thin gravity sensor rotates to ± 180 °, the steel column 105 does not shield any one of the optical signal transmitting chip 102 and the optical

signal receiving chips

103 and 104, and both of the output ends OUT1 and OUT2 of the optical

signal receiving chips

103 and 104 output a high level 1. When the ultrathin gravity sensor rotates to-90 degrees, the steel column 5 shields the optical signal receiving chip 104, the steel column 105 refracts the optical signal emitted by the optical signal emitting chip 102 to the optical signal receiving chip 103, the output end OUT1 corresponding to the optical signal receiving chip 103 outputs a high level 1, and the output end OUT2 corresponding to the shielded optical signal receiving chip 104 outputs a low level 0. It can be seen that when the gravity sensor is at 0 °, 90 °, ± 180 °, -90 °, the output terminals OUT1 and

OUT2 output levels

00, 01, 11, 10, respectively. When the Micro Controller Unit (MCU) of the application equipment capable of rotating the picture receives the commands, the picture is correspondingly rotated, so that the front picture can be obtained at four horizontal angles.

The ultrathin gravity sensor adopts the steel column as the reflector, so that the thickness of the product is thinner, the volume is smaller, and the use is convenient. The arc edge is additionally arranged behind the light guide groove to shield the optical signal, and the optical signal cannot shuttle from the gap between the steel column and the top cover, so that the shock resistance of the ultrathin gravity sensor is better, and the performance is more stable.

The sensing points of the pressure sensor 3 adopt pressure-sensitive ceramic chips inside the organic silicon, detect the pressure applied to the sports shoe body 9, collect 3D physical characteristic data and transmit the collected 3D physical characteristic to the controller.

When the user dresses sports shoes body 9 on the foot, gravity sensor 1 senses gravity and feels the change of gravity direction and all can transmit signal for controller 5, and controller 5 transmission signal gives time-recorder 2, and time-recorder 2 begins the timing, and time-recorder 2 transmission signal gives controller 5, then can collect time characteristic data, and time characteristic data includes ground contact time, flight phase duration, swing phase duration and rhythm.

The controller 52 comprises a control center 12, wherein a signal transmitting end of the controller is connected with a signal receiving end of the control center 12, and receives the data of the 3D physical characteristics and the time characteristics sent by the controller 5. The control center may be installed on a computer.

The control center adopts an upper computer and comprises a data receiving end and a KNN model algorithm end.

And the data receiving end receives the data information of the 3D physical characteristics and the time characteristics sent by the controller 2, filters and stores the data information, and sends the data to the KNN model algorithm end.

The KNN model algorithm end respectively calculates the distance between the objects as the non-similarity index between the objects for the received data of the 3D physical characteristics and the time characteristics, wherein the distance generally adopts Euclidean distance or Manhattan distance. And voting is carried out on the received motion through an algorithm model, whether the motion is possible to damage the user or not can be further provided, and a correct motion method can be further provided.

Because the disclosed sensor of the sports shoes of the disclosed sports shoes of this embodiment of a detection wearing time and motion dynamics, the data that obtain have two dimensions: a time dimension parameter, a 3D physical dimension parameter.

The time dimension parameters comprise ground contact time, flight phase duration, swing phase duration and rhythm; the 3D physical dimension parameters comprise tens of eigenvalues such as the pronation angle of the foot, the attack angle of the foot and the instantaneous speed estimated by a machine learning method, and compared with the effective dimension new messages in the general machine learning problem, the method has the advantages that the method is simple in structure and convenient to use.

in this example, the method for preventing sports injuries adopted in this example will be further described.

Because the sensor disclosed by the sports shoe for detecting the wearing time and the sports strength disclosed by the embodiment of the invention has two dimensions of acquired data: a time dimension parameter, a 3D physical dimension parameter. The time dimension parameters comprise ground contact time, flight phase duration, swing phase duration and rhythm; the 3D physical dimension parameters comprise tens of eigenvalues such as the pronation angle of the foot, the attack angle of the foot and the instantaneous speed estimated by a machine learning method, and compared with the effective dimension new messages in the general machine learning problem, the method has the advantages that the method is simple in structure and convenient to use. Because at different time points, the characteristic values have no direct correlation in either a time sense or a physical sense, and the points are independent in a high-dimensional space, the method is suitable for the KNN proximity algorithm. And KNN only calculates when receiving new data, can reduce a lot of calculated amount.

In this embodiment, the KNN proximity algorithm may be used as an algorithm model for preventing the motion impairment. The machine learning model KNN proximity algorithm is selected, and the KNN is classified by measuring the distance between different characteristic values. The idea is as follows: a sample belongs to a class if the majority of the K most similar samples in feature space (i.e. the nearest neighbors in feature space) belong to this class, where K is typically an integer no greater than 20. In the KNN algorithm, the selected neighbors are all objects that have been correctly classified. The method only determines the category of the sample to be classified according to the category of the nearest sample or a plurality of samples in the classification decision. Compared with the prior art, the method has more robustness and accuracy.

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that the present embodiments may be practiced without these specific details.

Referring to fig. 4, in this embodiment, on the basis of the first embodiment and the second embodiment, the collected data of the 3D physical characteristics and the time characteristics and the like are further analyzed, and based on the analysis result, whether the exercise performed may cause damage to the user or not may be further provided, and a correct exercise method may be further provided.

The specific process is as follows:

102, when the gravity sensor 1 senses that both gravity and gravity direction change transmit signals to the controller 5, the controller 5 transmits the signals of the gravity and gravity direction change to the timer 2, the timer 2 starts timing, next time the signals of the gravity and gravity direction change are received, the timer 2 finishes timing at the lower end of the period and starts timing, and transmits timing data signals of the period to the controller 5, so that time characteristic data can be collected; the time characteristic data comprises ground contact time, flight phase duration, swing phase duration and rhythm;

104, detecting the pressure applied to the sports shoe body 9 by the pressure sensor 3, collecting 3D physical characteristic data, and transmitting a signal to the controller according to the collected 3D physical characteristic;

106, the controller sends the data of the 3D physical characteristics and the time characteristics to a control center, and the control center filters and stores the data of the 3D physical characteristics and the time characteristics and sends the data to a KNN model algorithm end;

step 108, the KNN model algorithm end calculates the data of the 3D physical characteristics and the time characteristics through the KNN model algorithm respectively, and calculates the distance between the objects to serve as a non-similarity index between the objects;

110, voting the result in the step 108 through an algorithm model;

step 112, deducing whether the motion made is likely to cause damage to the user based on the voting model.

In the third embodiment, the KNN model algorithm of step 108 is described in detail.

In KNN, the matching problem between objects is avoided by calculating the inter-object distance as the non-similarity index between the objects, where the distance generally uses the euclidean distance:

or manhattan distance:

at the same time, KNN makes a decision by the dominant class among K objects, rather than a single object class decision. These two points are the advantages of the KNN algorithm.

The idea of the KNN algorithm is summarized next: that is, under the condition that the data and the labels in the training set are known, test data are input, the features of the test data are compared with the corresponding features in the training set, the first K data which are most similar to the features in the training set are found, the class corresponding to the test data is the class with the largest occurrence frequency in the K data, and the algorithm is described as follows:

(1) calculating the distance between the test data and each training data;

(2) sorting according to the increasing relation of the distances;

(3) selecting K points with the minimum distance;

(4) determining the occurrence frequency of the category where the first K points are located;

(5) and returning the category with the highest frequency of occurrence in the former K points as the prediction classification of the test data.

The KNN algorithm provided by the present invention has the following advantages, as can be seen from the foregoing embodiments: the method is simple, easy to use, easy to understand, high in precision, mature in theory, and capable of being used for classification and regression; can be used for numerical data and discrete data; training time complexity is o (n); no data input assumption;

insensitive to abnormal values. A reduction factor is introduced in each step, so that the influence on the result is reduced, a subsequent model has a larger optimization space, and overfitting is further prevented.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
