Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for monitoring a motion state, referring to fig. 1, the method includes the following steps:
and S11, obtaining sole pressure data when the monitoring object moves.
In this embodiment, can detect the plantar pressure data when monitoring the object removal through the shoes of the intelligent shoe-pad that have pressure sensor in this embodiment, plantar pressure data includes the pressure distribution condition of sole, can realize the detection of pressure distribution condition through setting up a plurality of pressure sensor, for example, set up a pressure sensor in first toe department, second toe department sets up from a pressure sensor, the sole sets up two sensors in the front, set up two sensors at the back sole, for the foreign body sensation when reducing the monitoring object removal, film pressure sensor can be chooseed for use, certainly also can have the special shoe-pad of draw-in groove, place ordinary pressure sensor in the draw-in groove and be used for detecting plantar pressure.
In this embodiment, pressure values at respective preset positions of the left sole and the right sole when the monitoring subject moves are acquired as sole pressure data.
Specifically, as shown in fig. 2, the step of obtaining the pressure value at each preset position includes the following steps:
and S21, acquiring the pressure value of the reference position around the preset position for each preset position.
And S22, for each preset position, carrying out weighted average on the pressure values of the reference position corresponding to the preset position according to the distance between the reference position and the preset position to obtain an average value, and taking the average value as the pressure value of the preset position.
In this embodiment, an average value is obtained by weighted averaging of pressure values of reference positions around a preset position, and as the pressure value of the preset position, the value of a certain point in a group of data is replaced by the value of each surrounding point, so that the influence of the noise point on the data is avoided, and the purpose of eliminating is further achieved;
wherein B is a pressure value of a preset position, a m For the sum of the distances of all reference positions from the predetermined position, a k For the kth reference position to be equidistant from the predetermined position, b k A pressure value for a kth reference position;n is the number of reference positions.
Specifically, in this embodiment, the pressure value at each preset position may also be obtained as follows: and aiming at each preset position, acquiring pressure values of a plurality of reference positions around the preset position, sequencing the pressure values of the reference positions, and taking the middle value of the pressure values of all the reference positions as the preset position pressure value to avoid noise interference, wherein the distance between each reference position and the preset position is smaller than a preset distance.
In this embodiment, since all data when the monitoring object moves do not completely conform to pressure data when the monitoring object moves in a natural gait, the data acquisition may be performed to obtain as many data as possible, and the plantar pressure data of each point is compared with each other to eliminate data with a large difference from most data, so as to reduce noise interference of a data terminal and improve data accuracy.
And S12, obtaining the left coordinate maximum deviation amount of the plantar pressure center of the monitored object and the right coordinate maximum deviation amount of the plantar pressure center according to the plantar pressure data.
In this embodiment, the plantar pressure center of the monitored object can be obtained based on the plantar pressure data, for example, by comparing the plantar pressure values of the corresponding positions of the left and right feet, and if they are equal, then the sole pressure center is the position in the middle of the detected human body, if only the sole pressure value of the left foot, the sole pressure center at this time is at the left foot, if only the sole pressure value of the right foot is available, the sole pressure center is at the right foot, the sole pressure center coordinate at the moment can be determined according to the size change of the sole pressure values of the left foot and the right foot and the coordinates of the left foot and the right foot, the sole pressure data of the left foot and the right foot can be averaged to obtain the average pressure data of the left foot and the right foot, the position change condition of the plantar pressure center is determined through the average pressure data, and the average can be carried out according to the pressure value and the coordinate position of each position of the left foot and the right foot to obtain the coordinates of the plantar pressure center.
In this embodiment, the coordinate position of the sole pressure center may be obtained according to coordinates of points acquired by sole pressure data, and may be obtained by using a coordinate system established by using any point of the human body as a coordinate origin, or may be obtained by using other reference objects as coordinate origins, and the application is not limited in this respect.
In this embodiment, if the center of the detected human body is taken as the origin of coordinates, the left-side coordinate is the minimum value of the plantar pressure center coordinates, and the right-side coordinate is the maximum value of the plantar pressure center coordinates.
In this embodiment, the maximum deviation of the left side coordinates of the center of sole pressure, that is, the deviation of the center of sole pressure between the maximum coordinates of the left side of the body of the monitored object, can be obtained by the same method, and the maximum deviation of the right side coordinates of the center of sole pressure can be obtained by the same method, because the maximum coordinates of the center of sole pressure only fall on the left foot and the right foot, when a normal person walks in a straight line, the coordinates of the left foot and the right foot theoretically only advance without deviation, but in actual conditions, even in an experimental environment, completely straight walking cannot occur, so that when the center of sole pressure falls on the left foot and the right foot, a certain deviation occurs, and the larger the deviation of the maximum coordinates of the center of sole pressure on both sides of the monitored object is, the better the motion state of the user is described, and not only the user can determine whether the leg or the foot of the user has a problem according to the motion state evaluation value, because the deviation amount of the normal person is not too large when the normal person walks normally.
And S13, obtaining the motion state evaluation value of the monitored object according to the left coordinate maximum deviation amount and the right coordinate maximum deviation amount.
In the embodiment, the condition of the deviation of the plantar pressure centers at the two sides of the monitored object is determined according to the maximum deviation amount of the left side coordinate and the maximum deviation amount of the right side coordinate, if the deviation of the pressure centers of the soles on the two sides is not large, the risk is small, the exercise state is good, in practical situations, people with poor exercise status often have injured feet or legs, other problems or poor walking habits, in order to reduce or avoid increasing pain in the problematic leg, a compensation strategy of relatively fast swing of the plantar pressure center conversion of the contralateral limb supporting leg is adopted, the process reduces the change of the knee joint varus moment at a point outside the supporting period, therefore, if the deviation amount on the left side is larger than the deviation amount on the right side, it is described that the right leg is a certain problem when the monitoring target walks, and conversely, the left leg is a certain problem.
In this embodiment, the exercise state may be determined according to the difference between the deviation amounts of the centers of pressure of the soles on the two sides, for example, an exercise state evaluation value corresponding to a difference range may be preset, and when the difference falls into any range, the exercise state evaluation value corresponding to the range may be used as the exercise state evaluation value of the monitoring object, and the gait and deviation amount of the monitoring object may be matched with the actual situation of the person in the past record, so as to obtain the situation of the person in the past record closest to the monitoring object, and generate the exercise state evaluation value according to the situation of the person.

Regarding step S31, refer to the description in step S11 for details, which are not repeated herein.
And S32, obtaining the motion trail of the plantar pressure center when the monitored object moves according to the plantar pressure data.
In this embodiment, the plantar pressure center condition of the monitored object is obtained through plantar pressure data, and the dynamic change of the plantar pressure center is the plantar pressure center movement track of the monitored object when the monitored object moves.
Specifically, with reference to the above embodiment, the plantar pressure center coordinate of the monitored object can be calculated by the following formula:
wherein, Y cop For monitoring the plantar pressure center ordinate, X of the subject cop For monitoring the plantar pressure center abscissa, y of the subject i Is the ordinate, x, of the ith preset position i As abscissa of the ith preset position, F i The pressure value of the ith preset position is, and r is the number of the preset positions.
Based on the above formula, it can be known that the pressure at each preset position will change continuously with the walking of the detected person, and the center of pressure on the sole will change accordingly.
And S33, obtaining the maximum value of the left coordinate of the plantar pressure center and the maximum value of the right coordinate of the plantar pressure center of the monitored object in each gait cycle according to the coordinates of the plantar pressure center motion trail.
In this embodiment, one gait cycle is the advancing process from the step of striding out the same foot from the heel to the step of landing the foot again, and in one gait cycle, the sole pressure center of the person performs one complete reciprocating to obtain the maximum value of the coordinates of the sole pressure center of the monitored object on the left side of the human body and the maximum value of the coordinates of the sole pressure center of the monitored object on the right side of the human body.
And S34, calculating the deviation of the maximum value of the left coordinate according to the maximum value of the left coordinate of the plantar pressure center in the asynchronous state period.
And S35, calculating the deviation of the right coordinate maximum value according to the maximum value of the right coordinate of the plantar pressure center in the asynchronous state period.
In this embodiment, the maximum deviation amount of the left side coordinate of the sole pressure center and the maximum deviation amount of the right side coordinate of the sole pressure center may be a difference between the maximum values of the left side coordinates of the sole pressure centers in two adjacent gait cycles and a maximum value of the right side coordinates of the sole pressure centers in two adjacent gait cycles, or may be an average value of the differences between the maximum values of the left side coordinates of the sole pressure centers in a plurality of adjacent gait cycles and an average value of the differences between the maximum values of the left side coordinates of the sole pressure centers in two adjacent gait cycles.
And S36, obtaining the motion state evaluation value of the monitored object according to the left coordinate maximum deviation amount and the right coordinate maximum deviation amount.
For step S36, reference may be made to the description in step S13, and this embodiment is not described herein again.
For example, as shown in fig. 4, the deviation of the left coordinate maximum value is calculated according to the maximum value of the left coordinate of the plantar pressure center in the asynchronous period; calculating the deviation value of the right coordinate maximum value according to the maximum value of the right coordinate of the plantar pressure center in the asynchronous period, and the method comprises the following steps:
and S41, acquiring the maximum value of the left coordinates of the plantar pressure center in any gait cycle and any previous gait cycle as a first maximum value and a second maximum value.
And S42, calculating the absolute value of the difference between the first maximum value and the second maximum value to be used as the maximum deviation amount of the left coordinate.
In this embodiment, the maximum value of the left-side coordinates of the center of plantar pressure in any two step periods is obtained, and the maximum deviation of the left-side coordinates is calculated.
And S43, acquiring the maximum values of the coordinates of the right side of the plantar pressure center in any gait cycle and any previous gait cycle as a third maximum value and a fourth maximum value.
And S44, calculating the absolute value of the difference between the third maximum value and the fourth maximum value to be used as the maximum deviation amount of the right coordinate.
In this embodiment, the maximum value of the right coordinate of the plantar pressure center in the same gait cycle as the two gait cycles is obtained corresponding to any one of the gait cycles, and the deviation of the maximum value of the right coordinate is calculated.
Further, as shown in fig. 5, a deviation amount of the left coordinate maximum value is calculated according to the maximum value of the left coordinate of the plantar pressure center in the asynchronous period; calculating to obtain the deviation value of the maximum value of the right coordinate according to the maximum value of the right coordinate of the plantar pressure center in different dynamic periods, and the method comprises the following steps of:
and S51, respectively calculating absolute values of differences of the maximum values of the left coordinates of the plantar pressure centers in the adjacent gait cycles, and respectively obtaining first deviation values.
S52, the average of all the first deviation amounts is used as the left-side coordinate maximum deviation amount.
In this embodiment, the absolute value of the difference of the maximum values of the left side coordinates of the plantar pressure centers in the continuous gait cycles is calculated to obtain a plurality of first deviation amounts, and since the absolute value of the difference of the maximum values of the left side coordinates of the plantar pressure centers in the continuous gait cycles is calculated, the number of the first deviation amounts is 1 less than the number of the gait cycles, all the first deviation amounts are averaged, the obtained average value is used as the maximum deviation amount of the left side coordinates, and the maximum deviation amount of the left side coordinates calculated by the scheme refers to more data, so that the noise interference can be effectively avoided.
And S53, respectively calculating the absolute value of the difference value of the maximum values of the right coordinates of the plantar pressure centers in the adjacent gait cycles, and respectively obtaining second deviation values.
S54, the average of all the second deviation amounts is defined as the right-side coordinate maximum deviation amount.
In this embodiment, similarly, the right-side coordinate maximum deviation value is calculated, so that the data accuracy is improved, and the interference of the interference item is reduced.
As shown in fig. 6, an embodiment of the present invention provides a method for monitoring a motion state, including the following steps:
and S61, obtaining sole pressure data when the monitoring object moves.

And S62, obtaining the left coordinate maximum deviation amount of the plantar pressure center of the monitored object and the right coordinate maximum deviation amount of the plantar pressure center according to the plantar pressure data.
For step S62, reference may be made to the description in step S12, and this embodiment is not described herein again.
And S63, dividing the left coordinate maximum deviation amount and the right coordinate maximum deviation amount to obtain the motion state evaluation value.
In this embodiment, the motion state evaluation value is the left-side coordinate maximum deviation amount and the right-side coordinate maximum deviation amount, so that when the motion state evaluation value is 1, the motion state of the monitoring target is the lowest, and when the motion state evaluation value is less than 1, as can be seen from the above-described embodiment, at this time, there is a certain risk in the left foot of the monitoring target, and when the motion state evaluation value is greater than 1, there is a certain risk in the right foot of the monitoring target.
