The standard pressure distribution refers to a pressure distribution of a correct posture among data measured using a posture corrector using pneumatic pressure for each weight and posture.

Hereinafter, a more specific embodiment of the pressure correction process according to the pressure distribution will be described with reference to FIG. 4.

4 is a diagram illustrating a process of pressure correction according to an embodiment of the present invention.

Referring to FIG. 4, FIG. 4 illustrates a case in which four moving plates 101 and four pressure sensors exist, and a standard pressure distribution 410 preset (eg, 60 Kg) corresponds to a user's weight. The standard pressure distribution corresponding to the case) and the pressure distribution 420 inputted by the user sitting on the chair, and injecting air into a region requiring pressure correction, thereby correcting the pressure distribution 430-the standard pressure distribution 410. ) Can be controlled so that the air injection can be derived.

That is, when the user is seated on the chair and the user is seated to the left as shown by the pressure distribution 420, the pressure distribution is confirmed, by supplying air to the air compression pad 100 on the left side that requires pressure correction The pressure can be corrected like the corrected pressure distribution 430.

In order to correct the pressure, the user may input a weight in an initial setting process to generate a control signal for supplying air according to the weight from a controller (not shown).

Also, in the process of recognizing the posture of the user by measuring the pressure, the correct posture of the user may be known using the wearable device.

The wearable device is worn on an ear, and a three-axis acceleration sensor and a three-axis gyro sensor are built in, and thus the user's posture, motion, and angle can be calculated.

The method of calculating the posture, motion, and angle of the user may measure accelerations in a rolling direction, a transverse direction, and a height direction, and measure rolling, pitch, and yaw angular velocities, and integrate the measured accelerations and angular velocities. The posture, motion and angle of the user can be calculated.

By using the wearable device and the pressure sensor, the user's posture may be accurately determined.

For example, if the pressure distribution measured by the pressure sensor yields a level similar to that of the standard pressure distribution, the pressure sensor may determine that the user is sitting in the correct posture, but is measured by the 3-axis acceleration sensor and the 3-axis gyro sensor of the wearable device. One result may determine that the user's posture is tilted forward.

At this time, the posture of the user's neck is incorrect and there is a risk of a disease such as turtle neck.

When a device for correcting posture using only a wearable device is used, the posture of the waist is corrected, but the shape of the chair is changed and the posture is corrected to an incorrect posture, thereby causing a situation in which the user's posture is broken.

Since the present invention uses a wearable device and a pressure sensor, it is possible to cope with various variables.

Meanwhile, another embodiment of correcting a posture by sensing pressure when a user is seated on a chair will be described below with reference to FIG. 5.

FIG. 5 is a diagram illustrating a process of extracting a region where pressure is concentrated and performing posture correction according to another embodiment of the present invention.

As in the exemplary embodiment of FIG. 5, the pressure of the user seated in the chair is received through six sensors, and the pressure value of each sensor may be converted into a coordinate system format and stored.

For example, the pressure input from each of the a1 sensor 501, a2 sensor 502, a3 sensor 503, a4 sensor 504, a5 sensor 505, and a6 sensor 506 is represented as a coordinate system (750). , 750, 0, 0, 0, 0) to set the coordinates as input coordinates, and calculate (0, 0, 0, 0, 0, 750, 750) which is the inverse of the input coordinates. Subsequently, after calculating the pressure concentration point 510 and the reciprocal point 530 corresponding to the input coordinates and the reciprocal coordinates, respectively, the intermediate point 520 which is the intermediate point between the pressure concentration point 510 and the reciprocal point 530 is calculated. After the extraction, a control signal for injecting air into a specific air compression pad may be generated such that the pressure concentration point corresponding to the generated input coordinate becomes the intermediate point 520. That is, as in the above embodiment, when the input coordinate is generated as (750, 750, 0, 0, 0, 0), since the pressure is concentrated in the upper portion (a1 sensor and a2 sensor part) on the drawing, The input coordinates are generated at the intermediate point 520 which is the intermediate point between the pressure concentration point 510 corresponding to the coordinates and the reciprocal coordinates 530 corresponding to the reciprocal coordinates (0, 0, 0, 0, 750, 750). By injecting air into the air compression pad provided in the upper region of the bed, the pressure concentrated in the upper region can be dispersed in the downward direction.

As described above, a simple and accurate user posture correction may be possible by controlling the air compression pad to calculate and correct a point where pressure is concentrated from the pressure value generated by the user's seating.

A portion where the pressure is measured more than the standard pressure distribution, the portion of the measured portion the pressure is high) A control signal for supplying air to the 100 may be generated by a controller (not shown).

The step 40 may transmit a control signal generated by the controller (not shown) to the motor 205.

The step 50 may generate power rising to a control signal received from the motor 205, and may transfer power generated by the motor 205 to a wire 209 connected to the pulley 206. .

The step 60 may transmit the power received by the wire 209 to the extension plate 208.

In step 70, the extension plate 208 may move by the power transmitted from the wire 209.

That is, when the wire 209 is pulled, the extension plate 208 may move toward the stationary plate 201, and when the wire 209 is released, the extension plate 208 is opposite to the stationary plate 201. Can be moved.

The step 80 may supply air from the pressure expansion tube 202 to the air compression pad 100 by the moving extension plate 208.

That is, when the extension plate 208 moves toward the stationary plate 201 and applies pressure to the pressure expansion tube 202, the air inside the pressure expansion tube 202 is compressed by the air compression pad 100. Can be supplied.

In step 90, when air is supplied from the air compression pad 100, the air compression pad 100 may expand and move the movable plate 101.
