The aerobic exercise mode of the weight-loading biofeedback device according to the present invention using such multiple connection will be described in detail later.

Hereinafter, the control unit 1 in which the weight-bearing biofeedback device according to the present invention performs a weight measurement mode, a static balance training mode, a balance evaluation mode, and an aerobic exercise mode will be described in detail.

First, as shown in FIG. 9, the weight measurement mode is automatically performed when there is no user's mode input, and in the weight measurement mode, the control unit 1 measures each of the four load cells 4 It is configured to output the sum of the weight load on the display (9). That is, if there is a user's mode input, the control unit 1 performs the input mode.

In addition, the control unit 1 may generate weight log data for comparison with the previously measured weight load, and transmit it to the external server 11.

Next, as shown in FIG. 10, when the static balance training mode is input, the control unit 1 receives the deviation value of each weight load measured by the four load cells 4. Thereafter, the control unit 1 grasps the location of the user's weight center in the load cell 4 according to the size of the input deviation value. Then, it is configured to selectively turn on the plurality of cells of the LED bar 10 located in the same quadrant where the weight center is located to provide real-time feedback for the user's balance training. Specifically, the control unit 1 has an effect of classifying the magnitude (how far from the center) of the deviation value of the weight load measured by the load cell 4 located in each quadrant.

In addition, the control unit 1 may generate static balance log data for comparison with the static balance training mode previously measured and transmit it to the external server 11.

Next, as shown in Figure 11, when the balance evaluation mode is input, the control unit 1, first, for the first time, the weight value of the deviation measured by each of the four load cells (4) Upon receiving the input, a user's weight center is grasped according to the size of the deviation value, and a preparation operation for selectively lighting the plurality of cells of the LED bar located in the same quadrant as the weight center is performed. In addition, by applying the time point after the preparation operation as a zero point reference, after tracking the position of the body weight point grasped from the four load cells 4 that change according to the user's movement for the second time, the body weight point for the second time It is configured to output the amount of change to the display (9), calculate the average position of the weight center during the second time, and output the left and right bias of the user to the LED (10) to perform the user's balance evaluation. That is, in the balance evaluation mode, the static balance training mode is performed for the first time as a preparation operation, and then the balance is evaluated without the lighting of the LED 10 for the second time after the zero point adjustment, and the result is finalized. Is to output to

Specifically, in the balance evaluation mode, as a preparatory operation, the control unit 1 measures the user's weight load on the load cell 4 for 5 seconds. At this time, as in the static balance training mode described above, the control unit 1 grasps the position of the user's weight center according to the deviation value of each weight load measured by the four load cells 4, and the weight score is The plurality of cells of the LED bar 10 positioned in the same quadrant as the positioned quadrant are selectively lit to provide feedback on the balance maintenance state of the user before the actual balance evaluation.

Thereafter, the control unit 1 controls the load cell 4 to apply the time point when the user's preparation operation is completed as a zero point reference, and then allows the user to measure the displacement of the user's weight load movement, thereby tracking the user's movement Can improve the accuracy of. Needless to say, this is distinguished from the above-described function of the zero adjustment unit 7.

Then, the control unit 1 tracks the change in the user's weight point for the second time, preferably 10 seconds, for a substantial balance evaluation. At this time, it is important not to light the LED bar 10 so that the user can not grasp the location of his or her weight center. The controller 1 outputs a change in the weight center to the display 9 to express the tracked result explicitly, calculates the average of the weight center, and calculates the average of the weight center, where the user's bias is further inclined. Is to output through the LED bar (10).

In addition, the control unit 1 may generate balance evaluation log data for comparison with the previously measured balance evaluation, and transmit it to the external server 11.

Next, as shown in FIG. 12, when the aerobic exercise mode is input, the control unit 1 receives an identification number from the external server 11 through the communication unit 8, and the external server ( 11) and performs multiple connections between the weight-bearing biofeedback device provided with a plurality of dogs. When the multiple connection is completed, of the plurality of weight-bearing biofeedback devices, the weight-loading biofeedback device corresponding to the identification number transmitted from the external server 11 is activated. Accordingly, in the activated weight-bearing biofeedback device, when the control unit 1 lights up the LED 10 and the load cell 4 detects a weight load, the control unit 1 lights up. Turn off the LED bar (10). Through this, in the aerobic exercise mode, a user can provide an aerobic exercise program through tracking of the LED bar 10, and the user moves to the lighted load cell 4 in the aerobic exercise mode to move the load cell 4 ) Can be transmitted to the external server 11 by scoring the reaction time and accuracy data so that it is turned off.

Here, the external server 11 may individually call the weight-bearing biofeedback devices in the order of identification number, or is relatively weak due to the deviation of the weight load measured in the static balance training mode and the balance evaluation mode. In order to train the muscles, the exercise program can be modified by intensively calling the weight-bearing biofeedback device at the corresponding location.

In addition, in the aerobic exercise mode, the weight-bearing biofeedback device may be placed on a wall rather than on the floor to promote upper limb movement.

In addition, the aerobic exercise mode operates one weight-loading biofeedback device in a server mode and the remaining plurality of weight-loading biofeedback devices in a client mode, thereby providing the externally loaded server 11 and a plurality of weight-loading biofeedback devices. Multiple connections between devices can be performed more easily. Fig. 13A shows the operation algorithm in the server mode, and Fig. 13B shows the operation algorithm in the client mode.

Specifically, in the server mode, as shown in FIG. 13A, the weight-load biofeedback device set to the server mode is multi-connected with a plurality of clients by replacing the functions of the external server, and assigns individual identification numbers to each client. Perform aerobic exercise mode by calling randomly. On the other hand, the client mode, as shown in Figure 13b, similar to the conventional aerobic exercise mode, aerobic exercise mode in a manner that turns on the LED bar upon receiving an individual identification number from the weight-loading biofeedback device set to the server mode. To perform. However, unlike the conventional aerobic exercise mode, the weight-load biofeedback device set to the server mode and the client mode transmits a light-off event to the weight-load biofeedback device set to the server mode when the LED is turned off, in the client mode. In the server mode, when an extinction event is detected, an algorithm configured to light up the LED bar by randomly calling again may be included.
