Description

TECHNICAL FIELD [0001] The present invention relates to a sensing apparatus and a balance training apparatus using the same,

In particular, the present invention relates to a sensing apparatus and a balance training apparatus using the sensing apparatus. More particularly, the present invention relates to a balance training apparatus, And a balance training apparatus using the same.

There are various exercises to improve the balance ability such as a pair of clerks or standing on the toe or heel. Most of these aids for exercise are used to rehabilitate stroke patients in hospital rehabilitation centers. Rehabilitation exercise devices are equipped with a load sensor on the footrests, helping to improve the balance ability by detecting the change of the front, rear and left and right loads of the feet.

Korean Patent Registration No. 10-1193473 discloses a balance and weight movement training apparatus capable of sensing a body balance and a shift in weight by allowing a person to stand on a foot plate having a load sensor attached thereto. When such a fixed load sensor is used, there is a problem in that it is necessary to perform the training only at a predetermined position where the load sensor is provided, and the system configuration becomes complicated.

In order to detect changes in weight shift, the degree of weight shift must be determined, so an analog value should be detected rather than a digital value. But it is enough to be able to detect only the digital value without the need to sense the analog value in order to measure the force that is exerted on the forefoot or the force exerted on the heel. For this purpose, it is possible to use a configuration in which the switch is turned on when a certain amount of force is applied by attaching a mechanical switch to the foot or heel portion of the foot. However, even in the case of a mechanical switch, it is difficult to bear weight, There is a durability problem.

In addition, in order to improve the balance ability, the movement effect is different according to how the distance between the foot and the floor is maintained in the case of the one-legged climber. Therefore, It is important to know. When using the load sensor, the pressure sensor or the mechanical switch, it is possible to judge whether the foot is attached to the floor or not, but it is difficult to determine the distance between the foot and the floor. there is a problem.

The object of the present invention is to provide a balance training apparatus capable of sensing a standing position of the forefeet of the foot or the heel of the foot, or sensing how far the foot is off the floor, thereby improving the balance ability.

Another problem to be solved by the present invention is to provide a sensing device capable of detecting the standing position of the forefoot or the heel of the foot in the equilibrium training device or the distance from the floor.

According to an aspect of the present invention, there is provided a balance training apparatus capable of performing balance training, comprising: a sensing unit that can be coupled to a foot and transmits signals of different sizes according to a distance between the foot and the floor; And a determination device for determining whether the forefoot or heel of the foot is in contact with the floor using the signals transmitted from the sensing device or determining how far the foot is from the floor. Wherein the sensing device includes a first illuminance sensor which is provided in a first area of the foot for contacting the forefoot and generates a first illuminance signal of a different size according to a distance between the first area and the floor, A second illuminance sensor installed in the second area and generating a second illuminance signal of a different size according to a distance between the second area and the floor, and a second illuminance sensor provided in the first illuminance sensor and the first illuminance sensor, And a transmitter for receiving the illuminance signal and the second illuminance signal and transmitting the same to the determination apparatus.

The determining device determines that only the foot of the foot is in contact with the floor when the first illuminance signal is equal to or greater than the first reference value and the second illuminance signal is less than the second reference value, When the first illuminance signal is greater than or equal to the first reference value and the second illuminance signal is greater than or equal to the third reference value, If the first illuminance signal is less than the second reference value and the second illuminance signal is less than the fourth reference value, it is determined that the forefoot and heel of the foot are in contact with the floor.

Wherein the determination device sets a value corresponding to 1 / n (n is a real number) of the maximum value of the first illuminance signal measured by the sensing device to the first reference value or the fourth reference value, A value corresponding to 1 / m (m is a real number) of the maximum value of the measured second illuminance signal may be set as the second reference value or the third reference value.

Wherein the first illuminance sensor generates a first illuminance signal equal to or greater than the first reference value if the distance between the first region and the floor is equal to or greater than a first reference distance, And the second illuminance sensor generates a second illuminance signal less than the fourth reference value if the distance between the second illuminance sensor and the bottom is equal to or greater than the second reference distance, And generate a second illuminance signal less than the second reference value if the distance between the second region and the floor is less than the second reference distance.

The judging device includes a section where only the forefoot of the foot should be in contact with the floor, a section in which only the heel of the foot is to be in contact with the floor, a section in which the forefoot and the heel of the foot must be in contact with the floor, The heel of the foot is in contact with the floor in each section displayed on the screen by using the first illuminance signal and the second illuminance signal, It is possible to determine whether the forefoot and the heel of the foot are both in contact with the floor and whether the forefoot and the heel of the foot are separated from the floor and to give a notification or to display the judgment result on the screen.

Wherein the judging device displays on the screen different intervals according to the distance between the foot and the floor when both the forefoot and the heel of the foot have to be separated from the floor, and the judging device displays the foot and the heel by using the first illuminance signal and the second illuminance signal, The distance of the floor may be determined and the determination result may be displayed on the screen.

According to another aspect of the present invention, there is provided a sensing device for transmitting signals of different sizes according to a distance between a foot and a floor, A first illuminance sensor installed in the first region and generating a first illuminance signal of a different size according to the distance between the first region and the floor and a second illuminance sensor provided in the second region in which the heel touches the second region, And a second illuminance sensor for generating a second illuminance signal of a different size according to the distance between the first illuminance sensor and the second illuminance sensor.

The sensing device according to an embodiment of the present invention and the balance training device using the sensing device according to the technical idea of the present invention generate an illuminance signal of a different size according to the degree of the sensing device falling from the floor, It is easy to judge how far it is from the floor, and there is an advantage that a simple device can exercise to improve balance ability. That is, according to the present invention, it is possible not only to determine whether the forefoot or heel of the foot is attached to the floor, but also to determine how far the foot has lifted from the floor, by using only the illuminance sensor without using a complicated device, There is an advantage to be able to do. In addition, the present invention can be implemented by applying a simple algorithm since the balance exercise can be performed only by judging whether the foot is standing on the forefle or standing on the heel of the foot, that is, the on / off concept. The present invention is advantageous in that a small illuminance sensor can be attached to a lower surface of a shoe, a bottom surface of a shoe, or a shoe insole to reduce the risk of damage even if it is used for a long period of time, . In addition, since it is possible to exercise by wearing shoes, shoes, or insole, there is no restriction of the place and there is no restriction on the position of the foot, so that it is possible to exercise while freely moving the foot in a comfortable place.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

FIG. 1 is a view schematically showing a balance training apparatus 100 according to an embodiment of the present invention.

Referring to FIG. 1, the balance training apparatus 100 may include a sensing device 110 and a determination device 130.

The sensing device 110 may be coupled to the foot, for example, a shoe, a boot, a shoe insole, or the like. However, the sensing device 110 of the present invention is not limited to this case, and may have various other shapes as long as it is coupled to the foot and can operate as described below. The sensing device 110 may transmit signals of different sizes depending on whether the forefoot or heel of the foot touches the floor or falls off. In addition, the sensing device 110 may transmit signals of different sizes depending on the distance the feet are away from the floor. The structure and operation of the sensing device 110 will be described in more detail with reference to FIGS. 2 to 5. FIG.

The determination device 130 may use the signals transmitted from the sensing device 110 to determine whether the forefoot or heel of the foot is in contact with the floor or how far the foot is from the floor. For example, when the signal related to whether or not the forefoot contact of the foot is equal to or greater than the first reference value and the signal related to the contact of the foot heel is less than the second reference value, only the heel of the foot contacts the floor . As another example, when the signal related to whether the heel of the foot of the sensing device 110 is in contact with the foot is equal to or greater than the third reference value and the signal related to whether or not the foot of the foot contacts with the foot is less than the fourth reference value, . As another example, if the signal related to whether or not the forefoot contact of the foot is greater than the first reference value and the signal related to the contact of the foot heel is greater than or equal to the third reference value, It can be judged. In this case, the determination device 130 may determine how far the feet are separated from the floor by using the magnitude of the signal related to whether or not the forefoot of the foot contacts the foot and the size of the signal related to the contact of the foot of the foot. The determination method of the determination device 130 will be described in more detail with reference to FIGS. 4 to 9. FIG.

The determination device 130 may determine whether the foot is in contact with the floor only when the foot of the foot is in contact with the floor and the foot of the foot is in contact with the floor only. Alternatively, when both the forefoot and the heel of the foot have to be separated from the floor, the judging device 130 may judge whether or not the exercising is performed according to the distance between the foot and the floor after displaying on the screen. This operation will be described in more detail with reference to FIGS. 6 to 9. FIG.

FIG. 2 is a block diagram schematically showing the configuration of the sensing device 110 of FIG. 1, and FIG. 3 is an exemplary view illustrating a sensing device 110 of FIG. 1 as a shoe insole. 4 to 6 are views briefly showing a state of exercise using the sensing device 110 of FIG.

Referring to FIGS. 1 to 6, the sensing device 110 may include a first illuminance sensor 210 and a second illuminance sensor 220. The first illuminance sensor 210 may be coupled to a first region of the foot contacting the forefoot and the second illuminance sensor 220 may be coupled to a second region of the foot. For example, when the sensing device 110 is a shoe insole, the first illuminance sensor 210 is coupled to a region of the foot contacting the forefoot, and the second illuminance sensor 220 ) Can be combined.

The first illuminance sensor 210 may generate the first illuminance signal SEN_1 having a different size depending on the distance between the first region and the floor. Also, the second illuminance sensor 220 may generate the second illuminance signal SEN_2 having a different size depending on the distance between the second region and the floor.

That is, the first illuminance sensor 210 and the second illuminance sensor 220 may be sensors that can sense the amount of light that flows through the bottom surface of the sensing device 110. Therefore, the first illuminance sensor 210 and the second illuminance sensor 220 can generate illuminance signals of different sizes because the amount of light to be sensed differs according to the distance from the floor. For example, when the first illuminance sensor 210 is in contact with the floor, the first illuminance sensor 210 can not detect the light so that the amount of light to be sensed is small or absent. The amount of light to be detected is increased. Accordingly, the first illuminance sensor 210 may generate the first illuminance signal SEN_1 of different magnitudes depending on whether the first region is in contact with the floor or not. In the case of the second illuminance sensor 220, the second illuminance signal SEN_2 having a different size depending on the distance between the second region and the floor can be generated for the same reason.

For example, the first illuminance sensor 210 may generate the first illuminance signal SEN_1 above the first reference value if the distance between the first region and the bottom is equal to or greater than the first reference distance. Also, the first illuminance sensor 210 may generate the first illuminance signal SEN_1 less than the fourth reference value if the distance between the first region and the bottom is less than the first reference distance. Likewise, the second illuminance sensor 220 may generate the second illuminance signal SEN_2 equal to or greater than the third reference value if the distance between the second region and the floor is equal to or greater than the second reference distance. Also, the second illuminance sensor 220 may generate the second illuminance signal SEN_2 less than the second reference value if the distance between the second region and the floor is less than the second reference distance.

 The first reference value and the fourth reference value may be the same value or the first reference value may be a value larger than the fourth reference value. The third reference value and the second reference value may be the same value, and the third reference value may be a value larger than the second reference value. The first reference value to the fourth reference value may be a value generated by the determining device 130. That is, the determination device 130 sets a value corresponding to 1 / n (n is a real number) of the maximum value of the first illuminance signal measured by the sensing device as the first reference value or the fourth reference value, A value corresponding to 1 / m (m is a real number) of the maximum value of the second illuminance signal measured by the sensing device may be set as the second reference value or the third reference value. The maximum value of the first illuminance signal may be the first illuminance signal measured by the first illuminance sensor 210 when the user's foot heel is attached to the floor and only the forefoot of the foot is dropped from the floor as much as possible. Also, the maximum value of the second illuminance signal may be the second illuminance signal measured by the second illuminance sensor 220 when the user's foot is attached to the floor and the heel of the foot is dropped from the floor as much as possible. This is because each user has different degrees of heel or heel to the maximum of the foot, and the brightness of the surroundings is different from each other, so the user sets the standard of motion before the user exercises.

In addition, the first reference distance and the second reference distance may be the same value or different values. For example, since the maximum distance at which the heel can be separated from the floor when the user is standing with the forefoot and the maximum distance at which the forefoot can fall from the floor when the user is standing with the heel, the first reference distance and the second reference distance can be set differently have.

At least one of the first reference distance, the second reference distance, the first reference value, and the second reference value may be set differently according to the exercise intensity. If the first reference distance, the second reference distance, the first reference value, and the second reference value are high, it can be determined that the forefoot of the foot or the heel of the foot fall far from the floor to stand as the heel of the foot or the forefoot of the foot . In addition, the fact that the first reference distance, the second reference distance, the first reference value, and the second reference value are low means that the forefoot of the foot or the heel of the foot is standing at the heel of the foot or the forefoot of the foot, It can be judged. Therefore, for example, when a person having a relatively good balance ability performs a movement for achieving a higher balance ability, the first reference distance, the second reference distance, the first reference value, and the second reference value are set high . As another example, when a person having a relatively poor balance ability performs a movement for raising the balance ability to a normal level, the first reference distance, the second reference distance, the first reference value, and the second reference value may be set low .

The sensing device 110 may further include a transmission unit 230. The transmitting unit 230 receives the first illuminance signal SEL_1 generated by the first illuminance sensor 210 and the second illuminance signal SEL_2 generated by the second illuminance sensor 220 and transmits the second illuminance signal SEL_2 to the determination unit 130 Lt; / RTI > The transmission unit 230 can communicate with the determination apparatus 130 by wire or wirelessly.

The determining device 130 determines whether the forefoot or heel of the foot is in contact with the floor by using the first illuminance signal SEL_1 and the second illuminance signal SEL_2 received from the transmitter 230, It can be judged whether or not it is apart. For example, when the first illuminance signal SEL_1 is equal to or greater than the first reference value and the second illuminance signal SEL_2 is less than the second reference value, the determination device 130 determines that only the heel of the foot is in contact with the floor, Can be judged as standing on the heel of the foot. Alternatively, when the first illuminance signal SEL_1 is less than the fourth reference value and the second illuminance signal SEL_2 is greater than or equal to the third reference value, the determining device 130 determines that only the forefoot of the foot is in contact with the floor, Can be judged as standing only on the forefle of the foot. When the first illuminance signal SEL_1 is equal to or greater than the first reference value and the second illuminance signal SEL_2 is equal to or greater than the third reference value, the determination apparatus 130 may determine that the foot is off the floor. In this case, the determination device 130 can determine the distance the feet are away from the floor according to the magnitude of the first illuminance signal SEL_1 and the second illuminance signal SEL_2. For example, when the first illuminance sensor 120 and the second illuminance sensor 130 are 20 cm apart from the floor, the determination device 130 determines that the first illuminance signal SEL_ 1 and the second illuminance signal SEL_ The size can be used to determine that the feet are 20 cm away from the floor. The magnitude of the first illuminance signal SEL_1 and the second illuminance signal SEL_2 depending on the distance between the feet and the floor may be stored in a database, As shown in FIG.

The function of the determination device 130 may be included in the transmission unit 230. That is, the determination device 130 may be included in the sensing device 110, and in this case, the sensing device 110 may perform the operations described in FIGS. 6 and 7.

FIG. 4 is a view for explaining the operation of the sensing device 110 of FIG. 1 when only the heel of the feet is touching the floor.

1 to 4, it is assumed that the distance 'a' between the first region and the bottom provided with the first illuminance sensor 210 is greater than the first reference distance. In this case, the first illuminance sensor 210 may generate the first illuminance signal SEL_1 equal to or greater than the first reference value. In FIG. 4, it is assumed that the distance between the second region where the second illuminance sensor 220 is installed and the bottom is smaller than the second reference distance. In this case, the second illuminance sensor 220 may generate the second illuminance signal SEL_2 less than the second reference value. Accordingly, the determining device 130 can determine that the first illuminance signal SEL_1 is equal to or greater than the first reference value and the second illuminance signal SEL_2 is less than the second reference value. 4, since the first illuminance sensor 210 generates the first illuminance signal SEL_1 that is less than the first reference value, the determination device 130 determines that the ' It can be determined that both the forefoot and the heel of the foot are in contact with the floor.

FIG. 5 is a view for explaining the operation of the sensing device 110 of FIG. 1 when only the forefoot of the foot is touching the floor.

1 to 5, it is assumed that the distance 'b' between the second region where the second illuminance sensor 220 is installed and the bottom is greater than the second reference distance. In this case, the second illuminance sensor 220 may generate the second illuminance signal SEN_2 equal to or greater than the third reference value. In FIG. 5, it is assumed that the distance between the first region and the first region where the first illuminance sensor 210 is installed is smaller than the fourth reference distance. In this case, the first illuminance sensor 210 may generate the first illuminance signal SEN_1 that is less than the fourth reference value. Accordingly, the determination device 130 can determine that the first illuminance signal SEN_1 is less than the fourth reference value and the second illuminance signal SEN_2 is greater than or equal to the third reference value. If 'b' is smaller than the second reference distance in the embodiment of FIG. 5, the second illuminance sensor 220 generates the second illuminance signal SEN_2 less than the second reference value, 130 may determine that both the forefoot and the heel of the foot are touching the floor.

6 is a view for explaining the operation of the sensing device 110 of FIG. 1 according to the distance between the feet and the floor when the feet are lifted from the floor.

1 to 6, it can be seen that the amount of light transmitted through the bottom of the sensing device 110 varies depending on the distance between the sensing device 110 and the floor. That is, comparing (a) and (b), (b) is higher than (a) 110). ≪ / RTI > Accordingly, (b) the first roughness signal SEN_1 or the second roughness signal SEN_2 generated by the position sensing device 110 is converted into the first roughness signal SEN_1 generated by the sensing device 110 at the position (a) Or the second illuminance signal SEN_2. Therefore, the determining device 130 can determine whether the feet are located at a certain height from the floor for the size of the first roughness signal SEN_1 or the second roughness signal SEN_2 generated by the sensing device 110. [

FIG. 7 is a view showing a section to be exercised by using the balance training apparatus 100 of FIG. 1, FIG. 8 is a view showing a state of displaying the determination result determined by the determination apparatus 130 of FIG. 1 on the screen of FIG. to be.

Referring to FIGS. 1 to 8, the judging device 130 may display on the screen a section 610 in which only the forefoot of the foot is to be in contact with the floor, and a section 630 in which only the foot of the foot is in contact with the floor. In FIG. 7, the left foot and the right foot are displayed separately. However, when only one foot is desired to be exercised, only information about one foot may be displayed on the screen. In addition, the function of displaying on the screen as shown in FIG. 7 may be performed by the determination apparatus 130, but may be performed by another apparatus. The screen shown in FIG. 7 may move to the left or right while moving the screen to continue the motion.

The determination device 130 may determine whether or not the forefoot or heel of the foot contacts the floor corresponding to each section displayed on the screen, and give a notification or display the determination result on the screen. For example, as shown in FIG. 8, 'O' may be displayed if it normally operates in the corresponding section, and 'X' may be displayed if it does not operate normally. However, the present invention does not necessarily have to be displayed as shown in FIG. 7, and if the user is able to show or inform the user whether he / she is normally exercising, he / she may display it in other ways or inform him / her through sounds or the like.

FIG. 9 shows another example of a screen in a state in which a section to be exercised and a determination result are displayed using the equilibrium training apparatus 100 of FIG.

Referring to FIGS. 1 to 9, it is possible to simultaneously display a determination result as to how far the foot is from the floor after displaying the reference value according to how far the foot is from the floor. For example, when both the forefoot and the heel of a foot have to be separated from the floor, the judging device 130 can display on the screen different intervals according to the distance between the feet and the floor. 9, the determination device 130 calculates the distance D2 from the bottom of the section between t1 and t2 and the distance D2 from the bottom of the section between t3 and t4. So that it can be displayed on the screen. In this case, it is possible to indicate whether it is the right foot or the left foot. It is then the 'determination result' portion that indicates how much the user has actually heard the foot. For example, the determination device 130 determines the distance between the sensing device 110 and the floor using the magnitude of the first roughness signal SEN_1 or the second roughness signal SEN_2 received from the sensing device 110 And an example showing the result of such determination is the 'determination result' part of FIG. In this way, it is possible to maximize the effect of balance training through climbing by showing the user how much he / have.
