Background

Balance is a kind of physical quality, which means the ability to keep the whole body in a stable state against external forces that break balance. Human beings can not be balanced in complex motions such as action, walking, running and jumping, and the current balance three-level division method comprises the following steps: static first-level balance refers to a process of keeping a certain posture stable when the eyes are opened and closed without the action of external force; automatic state secondary balance, which refers to the process of adjusting from one posture to another posture without external force; he is dynamic balance in three levels, which means the process of rapidly adjusting the mass center and posture to keep the body balanced when the body constitution and the heart change under the action of external force.

The balance of the human body needs to be satisfied when the human body stably stands, walks and completes complex actions, otherwise, the human body falls down, and therefore the human body balance detection method has important significance for balance capability detection. According to the research, the method comprises the following steps: male and female balance ability declines with age; compared with men and women at different ages, the male has better balance ability than the female.

In the solution of the present invention, the data processing module receives data collected by the sensors of each module, and then performs analysis processing on the data to obtain balance detection data in postures of static/dynamic/sitting and standing transfer of a human body, and hereinafter, taking the first balance detection module 20 for testing the static balance of a human body as an example, a working principle of the intelligent balance detection device provided by the present invention when performing a balance test on a human body is described, and working principles of the second balance detection module and the sitting and standing detection module are similar to those of the intelligent balance detection device, wherein the first test area 21 of the first balance detection module 20 is preferably a static rectangular test flat plate.

In the test scheme of human static balance, the inherent kinematic characteristic of the control of the static standing posture of the human body is that the center of gravity (COG) of the human body has tiny and irregular swinging, and the kinematic characteristic reflects the stability of the human body to the control of the standing posture. Therefore, the static balance ability of the human body can be measured according to the swing track of the center of gravity COG.

When the swing trajectory of a standing body is quantitatively measured, it is difficult to directly measure the swing trajectory of the COG, but the swing trajectory of the COG may be indirectly measured through mechanical analysis. When the human body is still and stands, the human body is mainly subjected to vertical downward Gravity (Gravity) and vertical upward supporting force of the supporting surface to the human body, and the Gravity is visually expressed as the pressure of the human body to the supporting surface and is vertical to the supporting surface, as shown in fig. 8.

The center of pressure (COP) of the human body on the supporting surface is the projection of gravity on the supporting surface, and the center of pressure (COP) is the projection point of COG on the supporting surface. When the COG swings, the movement characteristic can be reflected by the movement track of the COP, namely the track of the COP reflects the kinematic characteristics of the body swing. Therefore, the static equilibrium of the human body can be quantitatively measured by the relevant parameters of the COP trajectory, and the pressure of the human body on the supporting surface is a set of parallel force systems perpendicular to the supporting surface, and the COP is the center of the force system. The COP position can be obtained from the principle of calculation of the center point of the parallel force system, and assuming that the ML direction (left-right direction) is the X axis and the AP direction (front-back direction) is the Y axis when the human body stands, as shown in fig. 9, the magnitude of the measured pressure at the point (Xi, Yi) is Fi, the calculation formula of the COP coordinates (Xc, Yc) is:

according to the formula, the distribution position (Xi, Yi) and the size Fi of the pressure required for calculating the pressure center can be measured by the first pressure sensor of the first balance detection module. The plurality of first pressure sensors 22 are installed at the bottom of the first test area 21 to detect the pressure of the human body to the support surface (the first test area 21), and then the pressure center coordinate is calculated according to the pressure distribution of the plurality of first pressure sensors 22. In summary, the kinematic characteristics of the body swing can be quantitatively measured by the COP trajectory of the human body to the support surface, and the distribution of the pressure needs to be measured when calculating the COP.

The measurement of the COP center of pressure can be detected by the static detection module 20, and the number of the first pressure sensors 22 is 4 for example, but it is understood by those skilled in the art that the number of the first pressure sensors 22 is not limited to 4, and any number of the first pressure sensors can be used, and the operation principle is similar to that of 4 sensors. Four pressure sensors are used for measuring the pressure of different positions of the supporting surface, and the position coordinate of the COP can be calculated through a pressure center calculation formula, wherein the measurement scheme is shown in FIG. 9. The first pressure sensors 22, i.e., the pressure sensor 1, the pressure sensor 2, the pressure sensor 3, and the pressure sensor 4, are mounted at four corners of the rectangular first test area 21, the distance between the two sensors in the width direction is a, the distance between the two sensors in the length direction is b, the forces measured by the sensors are F1, F2, F3, and F4, respectively, and the sum of these forces is the gravity G.

The center of the first test area 21 is defined as the origin of coordinates, the ML direction (left-right direction) is defined as the X-axis, the AP direction (front-back direction) is defined as the Y-axis, and the COP test coordinate system is shown in fig. 10. The position coordinates of the four sensors S1 to S4 are (a/2, b/2), (a/2, -b/2), (-a/2, -b/2), (-a/2, b/2) in this order. The COP position coordinate at a certain moment can be obtained according to the calculation method of the COP of the pressure center, and the calculation method is as the formula:

the coordinate position of the COP pressure center can be displayed on the display module 11 in real time, points at different time can be connected into a gravity center track, and whether the gravity center of the human body is stable or not can be displayed according to the track curve, so that the static balance capability of the human body when the human body is in a static standing state can be measured.

Further, it is possible to develop some small games, for example, moving the center of gravity of the human body to a point in eight directions of the first test area 21, testing whether the center of gravity can be moved to a corresponding position with instructions at a certain time when the body swings, and reflecting the balance ability of the patient according to the moving time and trajectory. In addition, the patient can walk on the flat plate for a certain length, the gravity center track can be marked, three times of continuous walking are carried out, three groups of tracks are obtained, and whether the tester has the hemiplegia signs or not can be deduced according to the walking tracks.

The utility model also integrates the second balance detection module into the intelligent balance detection device, so that the intelligent balance detection device can not only detect the static balance of a tester, but also detect the dynamic balance of the tester. And the second balance detection module has simple structure, low cost and high practicability.
