In addition, in order to better understand the dynamic and static combined balance measuring device, the working process is described as follows:

when the static balance measurement is performed by the person to be measured, the second rotation shaft 7 is first rotated, the sleeve 41 is placed from the vertical position to the horizontal position, and then the spool 42 is extracted therefrom; then, a person to be measured stands on the pressure detection module 3, and the first body shaking amplitude (first body shaking video) and the foot shaking amplitude of the person to be measured in three standing postures are respectively acquired through the camera shooting module 5 and the pressure detection module 3, and then the data are transmitted to the controller 2 for processing and the processed data are displayed on the controller 2; the pressure detection module 3 judges the foot shaking amplitude through pressure change; then, the person to be measured moves from the first end of the sleeve 41 to the second end of the sliding column 42, the second body shaking amplitude (second body shaking video) of the person to be measured which rapidly moves through the telescopic balance beam is collected through the camera module 5, and the data are transmitted to the controller 2 for processing and displayed on the controller 2 after processing; when the balance is measured, the second rotation shaft 7 is required to be rotated to rotate the sleeve 41 to the vertical position, and the slide column 42 naturally slides back into the sleeve 41.

The static balance determines the gravity center offset through pressure change (foot shaking change) and body shaking change, namely, detects the static balance gravity center shaking amplitude. The dynamic balance principle is similar, and the gravity center offset of the gravity center passing through the left and right sides of the balance beam is judged. The controller 2 can draw a map according to the data of the shaking amplitude, belongs to the Android drawing technology, and finally displays the map (result) on the controller 2. That is, the balance capacity can be judged by the regularity of the pattern, the better the balance capacity, the more disordered the pattern, the worse the balance capacity. Wherein, the left-right pressure difference is set as an x-axis, the front-back pressure difference is set as a y-axis, and the gravity center offset position can be determined by plotting according to xy-axis data. For example, the xy axes are all 00, which indicates that the center of gravity is not shifted. In addition, the amount of offset (body shake amplitude) of the key points of the human body with respect to the center of the screen (display screen of the controller 2) is taken as the xy axis, and the human body shake amplitude is determined by drawing a map. For example, an offset of 0 indicates that the human body is not swaying.

Specifically, as shown in fig. 2, the pressure detection module 3 includes: chassis 31, two pedals 32, two spring assemblies 33, two transparent cover plates, two steel balls 323 and a plurality of pressure sensors 322;

It should be noted that the two pedals 32 are used for stepping on by both feet of the person to be measured. When the body of the person to be measured shakes, the shaking is transmitted to the sole of the foot, the shaking is transmitted to the pedal 32 by the sole of the foot, the steel balls 323 in the circular groove 321 roll to irregularly strike (collide) the pressure sensor 322, and the pressure sensor 322 collects signals and transmits the signals to the controller 2 for processing; moreover, the body shaking amplitude of the person to be measured can be judged by the frequency of the steel balls 323 knocking the pressure sensor 322, and the offset direction of the person to be measured during body shaking can be judged according to the frequency of the steel balls 323 knocking the pressure sensor 322 in different directions. The pressure detecting module 3 is similar to a level meter, and determines that the positions of the center of gravity of the human body on the pedal are different according to the pressure values received by the pressure sensors 322 in different directions, so as to determine which direction the human body deviates and shakes. That is, the pressure detection module 3 has accurate measurement data, and can visually display the deviation direction of the body of the person to be measured when the body is swayed, and no additional algorithm calculation is needed.

Further, as shown in fig. 1, the camera module 5 is rotatably connected to the top of the upright 1, so that the camera module 5 can be rotated toward the pressure detecting module 3 and can be rotated toward the retractable balance beam. The scheme is designed in such a way, the camera module 5 is convenient for collecting the first body shaking amplitude of a person to be measured in three standing postures and collecting the second body shaking amplitude of the person to be measured which walks through the telescopic balance beam. That is, the camera module 5 of the present embodiment not only can be used for measuring the static balance of the person to be measured, but also can be used for measuring the dynamic balance of the person to be measured, and has better practicability.

Still further, as shown in fig. 1, the camera module 5 is rotatably connected to the top of the upright 1 through a first rotation shaft 6. After the static balance of the person to be measured is measured, the camera module 5 can be aligned with the sleeve 41 and the slide column 42 by rotating the first rotating shaft 6. Of course, the camera module 5 also has a rotation self-locking function, which can be realized by a wheel locking device.
