1 is a block diagram of a foot pressure meter 10 according to an embodiment of the present invention, Figure 2 is an exemplary view illustrating a color range according to an embodiment of the present invention, Figure 3 is a foot pressure according to an embodiment of the present invention Exemplary diagrams illustrating display of measurement results.

Referring to FIG. 1, the foot pressure measuring apparatus 10 according to an exemplary embodiment of the present invention includes a sensor unit 100, a receiver 200, a controller 300, a calculator 400, and a display unit 500.

The sensor unit 100 is provided with a plurality of pressure sensors 130.

Preferably, it may consist of a sensor array of multiple rows and multiple columns.

In addition, since the sensor unit 100 measures the foot pressure of the user standing on the foot pressure measuring instrument 10 and stands up, it is preferable that the sensor unit 100 is formed in a size sufficient to measure the foot pressure of the user whose foot is larger than the average.

At this time, the pressure sensor 130 goes up to the foot pressure measuring instrument 10 to measure the pressure by the user's feet standing upright. For example, if 1000 pressure sensors 130 are provided in the sensor unit 100 and pressure is applied to the 700 pressure sensors 130 according to the size of the user's foot, which is 80KG, 700 sensors divide the pressure by 80KG. It means to receive.

The receiver 200 receives weight information of the user.

In this case, the receiving unit 200 may receive information on the weight of the user input through the input unit, or may be provided with a measuring sensor in the sensor unit 100 to measure the weight of the user.

Preferably, since there may be a weight change according to a specific situation for each user, the weight is directly measured through a measuring sensor of the sensor unit 100.

The controller 300 sets the measurement range of the pressure sensors 130 provided in the sensor unit 100 based on the weight of the user.

Preferably, the control unit 300 sets the measurement range of the pressure sensors 130 of the sensor unit 100 based on the weight of the user, but sets the maximum measurement range of the pressure sensor 130 to be lower as the weight is less. Do it.

In more detail, when the user's weight L is less than or equal to the reference weight K, the maximum measurement range of the pressure sensors 130 provided in the sensor unit 100 is changed from M to M × L / K.

This means that if the measurement range of the pressure sensors 130 is 0 to M, it is changed to 0 to M × L / K.

The purpose of this configuration is that if the user weighs enough, such as an adult male, since the pressure sensors 130 are subjected to high pressure, it is not unreasonable to measure and calculate the foot pressure. In the case of a lesser person, it may be difficult to measure and calculate the foot pressure due to the lack of pressure itself received by the pressure sensors 130.

Therefore, when the weight of the user is less than the predetermined reference weight, it means that the pressure sensor 130 to measure more finely by setting the maximum measurement range low.

For example, the pressure sensor 130 of the sensor unit 100 is able to distinguish a pressure in the range of 0 to 50 (in this case, the unit of pressure is ignored because it is a simple example), and is sufficient to measure the foot pressure. When the weight (reference weight) is set to 60 kg, and the user receives a weight of 30 kg (M = 50, K = 60 kg, L = 30 kg), M` = 50 × 30/60 = 25, and 0 Measure pressure in the range of ~ 25.

In addition, the control unit 300 sets the measurement range of the pressure sensors 130 based on the weight of the user, the lower the weight, the lower the maximum measurement range (M) of the pressure sensors 130, the set measurement range Match the color range previously stored, and assign a color to each measurement.

On the other hand, the shortcomings of the conventional method are described. Generally, when the measured value is low, the color of the blue (RGB 0, 0, 255) series is output, and the higher the measured value, the red (RGB 255, 0, 0) series The color of the is output. As such, when the user's weight decreases, the display itself has a fixed color according to the measured value, and thus the pressure difference is difficult to distinguish because the range of the displayed color itself is narrow.

Accordingly, in the foot pressure measuring apparatus 10 according to the embodiment of the present invention, the control unit 300 changes the maximum measurement range of the pressure sensors 130 according to the user's weight from M to M × L / K, and 0 to M The color ranges that are previously stored are matched to the measurement range set as, and colors are assigned to each measurement value.

For example, 0 is assigned to RGB (0, 0, 255), M is assigned to RGB (255, 0, 0), and RGB (255, 0, 0) in RGB (0, 0, 255) of FIG. This means dividing the color within n different colors and distributing them for each measured value.

In addition, the display unit 500 displays the measured values of the respective pressure sensors 130, and displays the measured values of the respective measured values through the control unit 300.

Therefore, the foot pressure measuring apparatus 10 according to the embodiment of the present invention has an effect that the measured values are displayed in various colors even when the weight of the user is small.

Since the color is rearranged based on the user's weight as described above, even a user who has a small weight such as a child may display the measured value in various colors as shown in FIG. 3.

The calculator 400 calculates the weight value loaded on each pressure sensor 130 through the weight information and the pressure value measured by the pressure sensor 130.

For example, the weight value of each of the pressure sensors 130 may be calculated based on the total pressure and weight of the pressure sensors 130 pressurized by the user's foot.

In addition, the calculation unit 400 divides colors according to pressure values or weight values corresponding to the respective pressure sensors 130 step by step, and displays the colors corresponding to the entire pressure sensors 130 of the sensor unit 100. Display as (500).

At this time, as shown in Figure 3, the pressure value or the weight value of the pressure sensor 130 is displayed as an RGB value, the lower the pressure value or weight value is displayed in the blue series, the higher the RED series.

In addition, the display unit 500 displays the weight value loaded on the pressure sensor 130 corresponding to the mouse click or mouse over point on the display unit 500.

As shown in FIG. 3, the pressure value and the weight value of the point where the mouse point is located may be displayed, or the pressure value and the weight value of the point where the mouse is clicked may be displayed.

Referring to FIG. 4, the calculator 400 divides a user's foot into four regions, the right foot and the left foot, and the pressure side and the back of the foot.

In addition, the calculator 400 calculates the weight on the user's right foot and left foot and the weight on the front and back of the foot and displays the weight on the display unit 500.

For example, as shown in FIG. 4, the user's foot is divided into four regions: a left front part D1, a left rear part D2, a right front part D3, and a right rear part D4.

Then, by comparing the weight (D1, D2) on the left foot and the weight (D3, D4) on the right foot, when the user is upright, it indicates whether the weight is properly distributed on both feet.

Then, by comparing the weight on the front (D1, D3) of the foot and the weight on the back (D2, D4) of the foot, when the user is upright, it indicates whether the weight is properly distributed on both feet.

Therefore, in the foot pressure measuring apparatus 10 according to the embodiment of the present invention, the length of both legs may be different according to a person, and due to an incorrect posture, the spine may be bent so that the weight difference on both feet may be severe. Therefore, accurate foot pressure can be measured to provide data to such a person.

5 is a flowchart of foot pressure measurement according to an embodiment of the present invention.

A procedure of measuring foot pressure according to an embodiment of the present invention will be described with reference to FIG. 5.

First, weight information of the user is received. (Step S510)

The receiver 200 receives weight information of the user. In this case, the receiver 200 may receive information about the weight of the user input through the input unit, or may receive the weight information of the user measured by the measurement sensor provided in the sensor unit 100.

Next, the measurement range of the pressure sensor 130 is set. (Step S520)

Preferably, the measurement range of the pressure sensors 130 of the sensor unit 100 is set based on the weight of the user, but the lower the weight, the lower the maximum measurement range of the pressure sensor 130 is set.

The method may further include assigning a color to each measurement value by matching the previously stored color range with the measurement range set through the controller 300 (step S525).

This means that the control unit 300 allocates different colors for each predetermined measurement range.

Next, the foot pressure is measured. (Step S530)

More specifically, the sensor unit 100 rises on the foot pressure measuring instrument 10 and measures the pressure by the user's feet standing upright.

Next, the weight value loaded on the pressure sensor 130 is measured. (Step S540)

The calculator 400 measures the weight value loaded on each pressure sensor 130 through the weight information and the pressure value measured through the pressure sensors 130 of the sensor unit 100.

Next, the measurement result is displayed through the display unit 500. (Step S550)

In more detail, the display unit displays the measured values of the pressure sensors, but displays them in the color assigned to each measured value. Preferably, the measurement value is displayed in color, but in step S525, the control unit displays the color assigned according to the measurement value.

Next, the user's body balance result is displayed through the foot pressure measurement result.

Preferably, the weight carried on the user's right foot and left foot and the weight carried on the front and back of the foot are calculated and displayed on the display unit 500.

In the above, embodiments of the present invention have been described with reference to the accompanying drawings, but those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features. I can understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
