Detail

In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments They are a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

As shown in Fig. 1, the present disclosure provides a method for monitoring the motion state. Referring to Figure 1, the monitoring method includes:

S11. Obtain plantar pressure data when the monitored object is moving;

S12. Obtain the maximum deviation of the left coordinate of the plantar pressure center of the monitored object and the maximum deviation of the right coordinate of the plantar pressure center according to the plantar pressure data; and

S13. Obtain the evaluation value of the motion state of the monitored object according to the maximum deviation of the left coordinate and the maximum deviation of the right coordinate.

In some embodiments, the sole pressure data of the monitored object can be detected by shoes with smart insoles with pressure sensors. The sole pressure data includes the pressure distribution of the sole. The pressure distribution can be achieved by setting multiple pressure sensors. Situation detection, such as setting a pressure sensor on the first toe, a pressure sensor on the second toe, two sensors on the forefoot, and two sensors on the back of the foot, in order to reduce foreign objects when the monitored object moves To sense, you can choose a film pressure sensor, of course, you can also use a special insole with a card slot, and place the ordinary pressure sensor in the card slot to detect the plantar pressure.

In some embodiments, the pressure value of each preset position of the left foot and the right foot when the monitored object moves is obtained as the plantar pressure data.

In some embodiments, as shown in FIG. 2, obtaining the pressure value of each preset position includes:

S21: For each preset position, obtain the pressure value of the reference position around the preset position; and

S22. For each preset position, the pressure value of the reference position corresponding to the preset position is weighted and averaged according to the distance between the reference position and the preset position to obtain an average value, which is used as the pressure value of the preset position.

In some embodiments, the weighted average of the pressure values of the reference positions around the preset position is used to obtain the average value, which is used as the pressure value of the preset position. To replace, so as to avoid this noise point from affecting the data, and then achieve the purpose of elimination. In some embodiments, the pressure value at the preset position is calculated as follows:

Wherein, B is a pressure value preset position, a _m value and pitch of all the reference position and the predetermined position, a _k is the k th reference position and the predetermined position equally spaced, b _k is the k th reference position The pressure value; n is the number of reference positions.

In some embodiments, the pressure value of each preset position can also be obtained in the following manner: For each preset position, obtain the pressure values of multiple reference positions around the preset position, and sort the pressure values of the reference positions , Taking the middle value of the pressure values of all reference positions as the preset position pressure value to avoid noise interference, wherein the distance between each reference position and the preset position is less than a preset distance.

In some embodiments, since all the data when the subject is moving will not completely match the pressure data of the natural gait, it is possible to obtain as much data as possible by comparing the plantar pressure data at each point with each other. Yes, remove the data that differs greatly from most data, reduce the noise interference of the data terminal, and improve the accuracy of the data. Alternatively, you can also set up multiple pressure sensors around the points that need to be collected. The average value of is used as the plantar pressure value at this point to reduce the interference of noise on the data, reduce the amount of data collection, and improve the processing efficiency.

In some embodiments, the plantar pressure center of the monitored object can be obtained based on the plantar pressure data. For example, the plantar pressure values corresponding to the left and right feet are compared. If they are equal, the plantar pressure center at this time is Detect the position in the middle of the human body. If there is only the plantar pressure value of the left foot, the plantar pressure center at this time is on the left foot. If there is only the plantar pressure value of the right foot, it means that the plantar pressure center is on the right foot. The changes in the plantar pressure values of the feet and right feet and the coordinates of the left and right feet determine the plantar pressure center coordinates at this time. The plantar pressure data of the left and right feet can also be averaged to obtain the average pressure data of the left and right feet. , Determine the position change of the plantar pressure center through the average pressure data, and average the pressure values and coordinate positions of each position of the left and right feet to obtain the coordinates of the plantar pressure center.

In some embodiments, the coordinate position of the plantar pressure center can be obtained according to the coordinates of the points collected by the plantar pressure data. It can be a coordinate system established by any point of the human body as the coordinate origin to obtain the coordinates of each point of the plantar, or Using other reference objects as the origin of the coordinates, the coordinates of each point on the sole are obtained, which is not particularly limited in the present disclosure.

In some embodiments, if the center of the detected human body is used as the origin of the coordinates, the maximum value of the left coordinate is the minimum value of the plantar pressure center coordinates, and the maximum value of the right coordinate is the maximum value of the plantar pressure center coordinates.

In some embodiments, the maximum deviation of the left coordinate of the plantar pressure center, that is, the deviation between the maximum value of the coordinate of the plantar pressure center on the left side of the body of the monitoring subject, and the plantar pressure can be obtained in the same way. The maximum deviation of the right coordinate of the center. Since the maximum coordinate of the plantar pressure center will only fall on the left and right feet, when a normal person walks in a straight line, the coordinates of the left and right feet will theoretically only move forward. There will be deviations, but in actual situations, even in an experimental environment, there will be no complete straight-line walking. Therefore, when the plantar pressure center falls on the left and right feet, there will be a certain deviation. The greater the deviation of the maximum value of the plantar pressure centers on both sides of the monitored object, the more indicating that the user's exercise state is not good. Not only that, the user can also determine whether there is a problem with his leg or foot based on the evaluation value of the exercise state. , Because when a normal person walks normally, the deviation will not be too large.

In some embodiments, according to the maximum deviation of the left coordinate and the maximum deviation of the right coordinate, the deviation of the plantar pressure center on both sides of the monitoring object is determined, if the deviation of the plantar pressure center on both sides is not much different , The risk is small and the exercise status is good. In actual situations, people with poor exercise status are generally injured in feet or legs, have other problems, or have poor walking habits. In order to reduce or avoid increasing the problem of the legs For pain, the compensation strategy of switching the plantar pressure center of the supporting leg of the contralateral limb faster will be adopted. This process reduces the change of the knee varus torque at a certain point outside the support period. Therefore, if the deviation of the left side is If the deviation is greater than the deviation on the right, it means that there is a certain problem with the right leg when the subject is walking, and vice versa, there is a certain problem with the left leg.

In some embodiments, the motion state can be determined based on the difference between the deviations of the plantar pressure centers on both sides. For example, the motion state evaluation value corresponding to the difference range can be preset, when the difference falls within any range. At the time, the exercise status evaluation value corresponding to the range is used as the exercise status evaluation value of the monitored object. It can also be matched according to the gait and deviation of the monitored object and the actual situation of the personnel in the past records to obtain the closest match to the monitored object The situation of the person in the past record of the person, and the evaluation value of the movement state is generated according to the situation of the person.

In some embodiments, referring to the foregoing examples, the plantar pressure center coordinates of the monitored object can be calculated by the following formula:

Among them, Y _cop is the ordinate of the plantar pressure center _{of the monitored object, X cop} is the abscissa of the plantar pressure center of the monitored object, y _i is the ordinate of the i-th preset position, and x _i is the i-th preset position The abscissa of F _i is the pressure value of the i-th preset position, and r is the number of preset positions.

Based on the above formula, it can be known that as the detected person walks, the pressure at each preset position will continue to change, and the plantar pressure center will also change accordingly.

In some embodiments, a gait cycle is the process of the same foot from stepping out of the heel off the ground to reaching the ground again. In a gait cycle, a person’s plantar pressure center will perform a complete reciprocation. Obtain the maximum value of the coordinates when the plantar pressure center of the monitoring object is on the left side of the human body and the maximum value of the coordinates when the center of the plantar pressure of the human body is on the right side of the human body.

S41. Obtain the maximum value of the coordinates of the left side of the plantar pressure center in any gait period and in the previous gait period, as the first maximum value and the second maximum value;

S42. Calculate the absolute value of the difference between the first maximum value and the second maximum value, and use it as the maximum deviation of the left coordinate;

S44. Calculate and obtain the absolute value of the difference between the third maximum value and the fourth maximum value as the deviation amount of the right coordinate maximum value.

In some embodiments, the maximum value of the left coordinate of the plantar pressure center in any two gait cycles is obtained, and the maximum deviation of the left coordinate is calculated.

In some embodiments, corresponding to any of the foregoing gait periods, the maximum value of the right coordinate of the plantar pressure center in the same gait period as the foregoing two gait periods is obtained, and the maximum deviation of the right coordinate is calculated.

It is also possible, as shown in Figure 5, to calculate the maximum deviation of the left coordinate according to the maximum value of the left coordinate of the plantar pressure center in the asynchronous state period; and according to the right of the plantar pressure center during the asynchronous state period The maximum value of the lateral coordinate, the maximum deviation of the right coordinate is calculated, including:

S51: Calculate the absolute value of the difference between the maximum value of the left side coordinate of the plantar pressure center in adjacent gait periods, respectively, to obtain the first deviation amount;

S52. Use the average value of all the first deviations as the maximum deviation of the left coordinate;

S53: Calculate the absolute value of the difference between the maximum value of the right coordinate of the plantar pressure center in the adjacent gait periods, respectively, to obtain the second deviation amount; and

S54. Use the average value of all the second deviations as the maximum deviation of the right coordinate.

In some embodiments, the absolute value of the difference between the maximum value of the left coordinate of the plantar pressure center of the continuous gait cycle is calculated to obtain a plurality of first deviations, because the plantar of the continuous gait cycle is calculated The difference between the maximum value of the left coordinate of the pressure center. Therefore, the number of the first deviation is one less than the number of gait cycles. All the first deviations are averaged, and the average value obtained is regarded as the maximum value of the left coordinate Deviation, the maximum deviation of the left coordinate calculated by this scheme refers to more data, so it can effectively avoid the interference of noise.

In some implementations, in the same way, the maximum deviation of the right coordinate is calculated to improve the data accuracy and reduce the interference of interference items.
