1 to 3, the air mattress 10 includes a frame 11, an air pocket unit 12, an air supply line 13, a pressure measuring line 14, a valve 15, and an air pump 16. ), A pressure sensor 17, a microphone 18, and a control module 19.

The frame 11 forms an outer shape of the air mattress 10, and may be formed in a shape in which the air pocket unit 12 is seated and inserted therein.

The frame 11 may include a lower frame 111 and an upper frame 112. The lower frame 111 may be formed in a shape in which the air pocket unit 12 may be inserted. The upper frame 112 may be disposed on the upper surface of the air pocket unit 12 and the lower frame 112 in a state where the air pocket unit 12 is inserted into the lower frame 112. For example, the lower frame 111 may be made of a hard material such as wood, plastic, metal, and the upper frame 112 may be made of a soft material such as cloth or leather.

The air pocket unit 12 may include a plurality of air pockets 121. The air pocket unit 12 may be configured by arranging the air pocket 121 in a plurality of rows and columns.

The air pocket 121 is capable of injecting and discharging air therein. The air pressure inside the air pocket 121 may be adjusted according to the user using the air mattress 10. According to the air control of the air pocket 121, the user can be adjusted to a hard bed, a fluffy bed, etc., the strength of the air pocket 121 can be adjusted according to the user's body part or sleeping posture.

2 and 3, the air pocket unit 12 may include a plurality of air pockets 121, a flow path 122, and a fitting part 123.

The air pocket 121 expands by air inflow or contracts by air outflow. A plurality of such air pockets 121 may be connected to each other. For example, the air pocket 121 may be arranged in a plurality of rows and columns. For example, the air pocket 121 may be arranged in nine rows and five columns. In addition, the air pockets 121 adjacent to each row may be connected to each other.

In detail, the air pocket 121 may include an upper surface portion 1210, a lower surface portion 1220, a sealing portion 1230, and an inner space 1240.

The upper surface portion 1210 forms an upper portion of the air pocket 121. When the user is lying on the air mattress 10, the upper surface portion 1210 is a portion for supporting the user, may be a portion directly receiving the load of the user. The upper surface portion 1210 may be pressed by the load of the user.

The upper surface portion 1210 may be formed by dividing into a plurality of surfaces inclined downward. The upper surface portion 1210 may include a first upper support surface 1211, a second upper support surface 1212, a first upper reinforcement surface 1213, and a second upper reinforcement surface 1214.

The first upper support ground 1211 and the second upper support ground 1212 may be disposed to be symmetrical to face each other based on one vertex. The first upper reinforcement surface 1213 and the second upper reinforcement surface 1214 may be disposed to face each other on both sides of the first upper support surface 1211 and the second upper support surface 1212. That is, the first upper support surface 1211 and the second upper support surface 1212 may face each other, and the first upper reinforcement surface 1213 and the second upper reinforcement surface 1214 may be disposed to face each other.

Specifically, one side of the first upper support surface 1211 is in contact with the other side of the first upper reinforcement surface 1213, and one side of the first upper reinforcement surface 1213 is the second upper support ground 1212. It may be in contact with the other side of the. In addition, one side of the second upper supporting surface 1212 may be in contact with the other side of the second upper reinforcing surface 1214. One side of the second upper reinforcing surface 1214 may be connected to be in contact with the other side of the first upper supporting surface 1212.

In this case, the first upper support surface 1211, the second upper support surface 1212, the first upper reinforcement surface 1213 and the second upper reinforcement surface 1214 are formed in a triangular shape and meet at one vertex, May be disposed adjacent to each other.

For example, the upper surface portion 1210 is formed of a total of four surfaces, it will be described with an example that the upper surface portion 1110 is in the form of a square pyramid. However, the present invention is not limited thereto, and the upper surface portion 1210 may be formed in a pentagonal pyramid including five side surfaces, and may include all other various forms.

Since a plurality of surfaces of the upper surface portion 1210 are formed to be inclined, a vertical surface may not be formed. That is, the upper surface portion 1210 formed to be inclined downward is not horizontal to the pressure direction according to the load of the user applied from the upper side. In other words, since the upper surface portion 1210 is formed of an inclined surface, the upper surface portion 1210 does not face the pressure direction.

The inclined upper surface portion 1210 may distribute the load of the user applied to the upper surface portion 1210, thereby preventing the depression or shape deformation of the air pocket 12 pressed by the user's load.

In detail, the upper surface 1110 under the load of the user is pressed downwardly, that is, inside the air pocket 110 by the load of the user. As in the conventional air pocket, when the upper surface and the side is vertical and there is a surface perpendicular to the air pocket, when the air pocket 121 is pressed inward by the user's load, between the upper surface and the side formed vertically The difference in height occurs. If such a difference in height occurs repeatedly, the edge portion of the air pocket can be easily recessed and the air pocket may be broken.

In order to prevent this, the upper surface portion 1210 according to the embodiment of the present invention is formed of a plurality of downwardly inclined surfaces that meet at one vertex, so that the surfaces forming the upper surface portion 1210 are applied to the upper surface portion 1210. The load may not be formed in opposite directions. Thus, even if the upper surface portion 1210 receives a load, it is possible to reduce the breakage rate of the air pocket 12 according to the load. Accordingly, the upper surface portion 1210 formed of the inclined surfaces may prevent the air pocket 121 from collapsing or abnormally recessed as the stress is concentrated due to the load of the user.

In addition, when air is supplied to the air pocket 121, the air pocket 121 is expanded. Conventional air pockets are in contact with each other when adjacent air pockets are inflated and, by contact between adjacent air pockets, inhibits pressure build up inside the air pockets. However, according to an embodiment of the present invention, the upper surface portion 1210 is formed to be inclined downward based on one vertex, so that even if the air pocket 121 is expanded, no contact occurs between adjacent air pockets 121. Can be.

The lengths of the bottom sides of the first upper support surface 1211 and the second upper support surface 1212 are not formed at least equal to the lengths of the bottom sides of the first upper reinforcement surface 1213 and the second upper reinforcement surface 1214. Can be. Specifically, the lengths of the bottom sides of the first upper support surface 1211 and the second upper support surface 1212 may be formed longer than the lengths of the bottom sides of the first upper reinforcement surface 1213 and the second upper reinforcement surface 1214. Can be.

Therefore, when the first upper support ground 1211 and the second upper support ground 1212 are pressed by the load of the user, the first upper support ground 1211 and the second upper support ground 1212 are bent more. As the paper is pressed in a curved shape, air below the first upper support surface 1211 and the second upper support surface 1212 may expand.

In this case, as the expanded air moves to the first upper reinforcing surface 1213 and the second upper reinforcing surface 1214, the first upper reinforcing surface 1211 and the second upper reinforcing surface 1212 may expand. .

As such, the first upper supporting surface 1211, the second upper supporting surface 1212, the first upper reinforcing surface 1213, and the second upper reinforcing surface 1214 are moved by the movement of the air in the air pocket 121. As the) contracts and expands, the air pocket 121 is not damaged and the pressure inside the air pocket 121 can be stably maintained.

The lower surface portion 1220 forms a lower portion of the air pocket 121. For example, the lower surface part 1220 may be in contact with the lower frame 111. The lower surface part 1220 may support a load of a user applied to the upper surface part 1210 below the upper surface part 1210.

The lower surface part 1220 may be formed by dividing the lower surface part 1220 into a plurality of inclined surfaces so as to be symmetrical with the upper surface part 1210. The lower surface part 1220 is symmetrical with the upper surface part 1210 and may be connected to the upper surface part 1210.

The lower surface part 1220 may include a first lower support surface 1221, a second lower support surface 1222, a first lower reinforcement surface 1223, and a second lower reinforcement surface 1224.

The lower surface part 1220 may be formed in a shape corresponding to the upper surface part 1110. That is, the first lower support surface 1221, the second lower support surface 1222, the first lower reinforcement surface 1223, and the second lower reinforcement surface 1224 are the first upper support ground 1211 and the second upper support ground. 1212, the first upper reinforcing surface 1213, and the second upper reinforcing surface 1214, and correspond to the shapes, functions, and effects of the respective components.

The sealing portion 1230 may be formed at a portion where the upper surface portion 1210 and the lower surface portion 1220 are connected to each other. Specifically, the sealing unit 120 is formed along the circumference of the upper surface portion 1210 and the circumference of the lower surface portion 1220 to seal the inner space 1240 inside the upper surface portion 1210 and the lower surface portion 1220. Can be.

The inner space 1240 may have a hollow shape formed therein while the upper surface portion 1210 and the lower surface portion 1220 are connected to each other. As air is injected into or discharged from the inner space 1240, the pressure of the air pocket 121 may be adjusted.

The flow path 122 may communicate the plurality of air pockets 121 arranged in each row. Therefore, the air can move between the plurality of air pockets 121 arranged in each row.

Specifically, the flow path 122 communicates the air pocket 121 adjacent to each row. That is, the flow path 122 communicates air between adjacent air pockets 121 arranged in the horizontal direction. One or more of the passages 122 may be formed between the adjacent air pockets 121. Preferably, two flow paths 122 may be formed between the adjacent air pockets 121.

For example, when the air pocket 121 is formed in nine rows, the flow path 122 may be formed in each row to communicate the air pocket 121 in each row.

The fitting part 123 may be installed in the air pocket 121 to fix the air pocket 121, the air supply line 13, and the pressure measurement line 14 to be described later.

The fitting part 123 may be an inlet for supplying and discharging air to the air pocket 121. The fitting part 123 may be disposed in each row. Specifically, the fitting part 123 may be installed in each of the air pockets 121 on both sides disposed at the edges of the plurality of air pockets 121 arranged in each row. For example, the fitting part 123 may be installed at one side air pocket 121 of each of the plurality of rows, and may be connected to the air supply line 13, and the fitting part 123 may be the other air pocket of each of the plurality of rows. Installed at each of 121 may be connected to the pressure measuring line 14.

The fitting part 123 may be installed to communicate with the air pocket 121 and each line stably so that the air does not leak to the outside and is movable only within the air pocket 121 and the lines.

In the present embodiment, the air pocket unit 12 will be described with an example including the air pocket 121 arranged in 9 rows x 5 columns.

The air pocket unit 121 constituting 9 rows x 5 columns may adjust the pressure of the air pocket 121 in each row. Therefore, the user can lie down without distinguishing the upper and lower parts of the air mattress 10. That is, even when lying on the air mattress 10 in any direction, it is possible to adjust the pressure of the air pocket 121 according to the user's body shape or sleeping posture. In addition, the pressure of the air pocket 121 may be adjusted to correspond to the user's body such as a child and an adult.

In addition, an interval between the rows of the air pockets 121 disposed in the air pocket unit 12 may be 150 mm. This is an interval that may not interfere with each other between adjacent air pockets 121 when the air pockets 121 are inflated. In addition, the spacing between the rows may be 125 mm. However, the present invention is not limited thereto.

The air supply line 13 may be connected to the fitting part 123 installed in one air pocket 121 of each of the plurality of rows of the air pocket unit 12. That is, the air supply line 13 may be connected to the air pocket 121 of each of the plurality of rows. The air supply line 13 is in communication with each of the plurality of fitting portions 123.

The air supply line 13 may connect the fitting part 123 and the valve 15. One end of the air supply line 13 is connected to an air pocket 121 disposed at one side of each row, and the other end is a valve 15 for supplying or discharging air to the air pocket 121 of each row. ) Can be connected.

Each of the air supply lines 13 may be formed by switching the air supply to the air pocket 121 and the air discharge of the air pocket 121 through the valve 15.

The pressure measuring line 14 may be connected to the fitting part 123 installed in the other air pocket 121 of each of the plurality of rows of the air pocket unit 12. That is, the pressure measuring line 14 may be connected to the air pocket 121 of each of the plurality of rows.

The pressure measuring line 14 may connect the fitting part 123 and the pressure sensor 17. The pressure measuring line 14 is connected at one end to an air pocket 121 disposed at the other side of each row, and the other end thereof is a pressure sensor 17 for measuring the pressure of the air pocket 121 at each row. Can be connected.

In other words, the pressure measuring line 14 may connect the air pocket 121 and the pressure sensor 17 so that the pressure sensor 17 may measure the pressure of the air pocket 121 in each row.

The valve 15 may regulate the air supply from the air pump 16 to the air pocket 121 and the air discharge from the air pocket 121. The valve 15 is formed in the form of a solenoid valve. However, the present invention is not limited thereto and may include all types of various valves 15.

The air pump 16 may supply air to the air pocket 121 through the air supply line 13.

The pressure sensor 17 may measure the pressure of the air pocket unit 12.

The pressure sensor 17 measures the pressure of the air pocket 121, but may measure the pressure of the air pocket 121 in each row. According to the pressure measured by the pressure sensor 17, the control module 19 may control the air supply and the air discharge of each air pocket 121 to adjust the pressure of the air pocket 121.

The pressure sensor 17 may be connected with the pressure measuring line 14. Specifically, the pressure sensor 17 may be connected to all of the plurality of pressure measuring lines 14 respectively connected to the plurality of rows. The pressure sensor 17 connected to the pressure measuring line 14 may measure the pressure of the air pocket 121 in each row.

Since the pressure measuring line 14 is provided separately from the air supply line 13, the pressure sensor 17 may measure the pressure inside the air pocket 121 without passing through the valve 15. Thus, more accurate pressure measurement is possible.

Based on the pressure measured by the pressure sensor 17, the control module 19 may adjust the pressure of the air pocket 121.

The microphone 18 is installed in the air mattress 10 to recognize the sound. The microphone 18 may measure noise around the air mattress 10 during a use time of the air mattress 10. According to the sound recognized by the microphone 18, the snoring determination unit 198, which will be described later, may determine whether the user snores.

The control module 19 may adjust the pressure of the air pocket 121. For example, the pressure of the air pocket 121 may be adjusted by adjusting the opening and closing of the valve 15. At this time, the control module 19 may receive the pressure value of the air pocket 121 measured by the pressure sensor 17 through the pressure measuring line 14, thereby controlling the opening and closing of the valve 15.

8 is a block diagram of a control module of an air mattress according to an embodiment of the present invention.

Referring to FIG. 8, the control module 19 may include a mattress control unit 191, a mattress communication unit 192, a mattress memory unit 193, a sleep time measuring unit 194, a pressure change calculation unit 195, and a use area determination unit. The unit 196 includes a pressure adjustment amount calculation unit 197 and snoring determination unit 198.

The mattress control unit 191 may be mounted to the body part 12, and the mattress control unit 191 may control the air mattress 10. In detail, the mattress control unit 191 includes a mattress communication unit 192, a mattress memory unit 193, a sleep time measuring unit 194, a pressure change calculation unit 195, a pressure adjustment amount calculation unit 197, and a use area determination unit. 196, the pressure of the air pocket 121 in each row of the air pocket unit 12 may be adjusted according to the information transmitted from the snoring determiner 198 and the use area recognition unit 199.

The mattress communication unit 192 may communicate with the user terminal 30 and the server 50, which will be described later, to transmit and receive data. The mattress communication unit 192 may receive a setting value or user information from the user terminal 30. Here, the setting value includes a user's desired pressure strength, sleep time, etc., and may be a setting value for setting the conditions and environment of the air mattress 10. The user information may include a user's height, weight, clothing size, and health status. Information relating to the user's body, including the back.

The mattress communication unit 192 may be connected to the server communication unit 51 (see FIG. 10) to transmit measurement data to the server 50. Here, the measurement data includes a pressure measurement value measured in the air mattress 10, pressure change amount, sleep time, pressure adjustment amount for each row of the air pocket 121 and the like.

The mattress memory unit 193 may store setting values or user information received through the mattress communication unit 192. In addition, the measurement data measured and calculated by the pressure sensor 17, the sleep time measuring unit 194, the pressure change calculating unit 195, and the pressure adjusting amount calculating unit 197 may be stored.

The sleep time measuring unit 194 measures a sleep time through a time of using the air mattress 10. The time from the moment when the user turns on the air mattress 10 to the moment when it is turned off can be measured. For example, the time set by the user terminal 30 may be measured as a sleep time.

In addition, the sleep time measuring unit 194 may include a timer function. It may include an automatic shutdown function or an alarm function according to the sleep time set by the user. For example, after a time set by the user, a function such as a pressure adjusting function or a pressure measurement of the air pocket 121 of the air mattress 10 may be automatically terminated.

In addition, the sleep time measuring unit 194 may measure the time the user uses the air mattress 10 based on the pressure applied to the air pocket unit 12 even if the user does not set the sleep time. For example, the time during which a load is applied to the air pocket unit 12 can be measured, and this can be measured as the use time.

The pressure change calculator 195 may calculate a pressure change amount of the air pocket unit 12 while the user uses the air mattress 10. Specifically, the pressure change calculation unit 195 calculates the pressure change amount of the air pocket unit 12 using the pressure measurement value measured in real time by the pressure sensor 17 during the sleep time. The pressure change calculator 195 may calculate the pressure change amount whenever the pressure change of the air pocket 121 is detected.

For example, the pressure change amount may be a difference between an initial pressure measurement value initially set by a default value, a set value, or user information and a change pressure measurement value at which the pressure of the air pocket 121 is changed. In detail, when the pressure change calculation unit 195 calculates the pressure change amount at an interval of 1 hour, the pressure change calculation unit 195 may be a difference between the initial pressure measurement value and the change pressure measurement value. For example, the pressure change amount in T2 time can be calculated | required by subtracting an initial pressure measurement value from the change pressure measurement value in T2 time. Similarly, the pressure change amount in T3 time can be calculated | required by subtracting an initial pressure measurement value from the change pressure measurement value in T3.

Alternatively, the pressure change amount may be obtained by the difference between the measured change pressure values changed at one hour intervals. For example, the pressure change amount up to T2 time one hour after T1 time can be calculated by subtracting the pressure measured value at T1 from the pressure measured value at T2.

The use area determination unit 196 may determine a user's body condition and a state lying in the air mattress 10 according to the pressure change amount calculated by the pressure change amount calculation unit 195.

Specifically, a predetermined amount of air is basically injected into the air pocket 121 of the air mattress 10. This is referred to as a default value of the air pocket 121 pressure. That is, even if the user does not use, the air pocket 121 maintains a state in which a certain amount of air is injected.

In this state, when the user is lying on the air mattress 10, pressure is applied to the air pocket 121 in the area to which the user's load is applied. The pressure change of the air pocket 121 is sensed, and according to a result of the pressure change amount being calculated for each row by the pressure change calculator 195, the use area determiner 196 determines the use area of the air mattress 10. can do.

For example, the physical condition of the user may determine the height of the user according to how many rows of pressure of the air pocket unit 12 has occurred. For example, if the user is an adult, a pressure change may occur in the air pocket 121 of eight rows from the first to the eighth row, and if the user is a baby, the total from the third row to the sixth row Pressure changes may occur in the three air pockets 121.

In addition, the upper and lower directions of the user lying down, it can be determined that the user's upper body is located on the side where the pressure change is greater, the lower body of the user is located on the side where the pressure change is relatively small. Specifically, when the user is lying on the air mattress 10, the load on the upper body side including the shoulder, back than the lower body is greater than the load on the leg, foot. Therefore, it is possible to grasp that the upper body of the user is located on the side of the region with a larger load within the total number of rows used.

In addition, the use area determiner 196 may be divided into a plurality of zones within an area used by the user.

For example, the air pocket unit 12 that constitutes 9 rows by 5 columns may be divided into a plurality of zones. In this case, the user may be divided into a plurality of zones based on the location of the user's body part.

In exemplary embodiments, the air pocket unit 12 may be divided into a first zone 121-1, a second zone 121-2, a third zone 121-3, and a fourth zone 121-4. have.

The first zone 121-1 is a portion where the user's shoulders (or head and shoulders) are positioned and may be formed in one or more rows of the air pocket units 12.

The second zone 121-2 is a portion in which the waist of the user is positioned and may be formed in one or more rows of the air pocket units 12.

The third zone 121-3 is a portion where the hip of the user is located, and may be formed in one or more rows of the air pocket units 12.

The fourth zone 121-4 is a portion in which the thigh and the knee of the user are positioned, and may be formed of a plurality of rows of the air pocket units 12.

Areas may be divided based on a plurality of rows of the air pocket 121 used by the user. For example, when all nine air pockets 121 are pressurized by the user's elongation, the first zone 121-1 consists of two rows and the second zone 121-2 has one row. The third zone 121-3 may be formed in two rows, and the fourth zone 121-4 may be formed in four rows. Alternatively, when the young child uses the air mattress 10 to apply pressure to the four air pockets 121, the first zone 121-1 to the fourth zone 121-4 may be formed in one row. Can be. However, the present invention is not limited thereto, and regions may be divided in various ways according to the physical condition of the user.

Hereinafter, the use area determining unit 196 includes two rows of the first zone 121-1, one row of the second zone 121-2, and three zones 121-3 of the third zone 121-3. It is made up of two rows, and the fourth zone 121-4 is divided into regions to have four rows.

Meanwhile, the part where the user's head and foot are located may be a fifth zone (not shown). Where the head is located, the air pocket 121 is not disposed, it may be formed of a general mat. In general, the part where the head is located may not be disposed because the air pocket 121 may not be necessary because the user uses a pillow or a pressure change. Similarly, the air pocket 121 may not be disposed where the foot is located. However, the present invention is not limited thereto, and the air pocket 121 may be disposed on the head and the foot of the user, and the pressure may be adjusted.

The pressure adjustment amount calculation unit 197 calculates a pressure adjustment amount for positioning the pressure of the air pocket unit 12 within an optimum air pocket pressure range according to a user through the calculated pressure change amount. For example, the pressure adjustment amount calculation unit 197 may calculate the pressure adjustment amount for each user's body so that the user may feel comfortable according to the user's sleeping posture.

Here, the optimum air pocket pressure range may be a range from a predetermined lower limit value of the pressure determined by the set value and the user information to a predetermined upper limit value.

The pressure adjustment amount calculation unit 197 may calculate the pressure adjustment amount according to an area in which a plurality of rows are divided into a plurality of rows according to the user's body condition, lying position, etc. calculated by the use area determination unit 196, which will be described later.

Specifically, in the zone where the pressure change amount of the plurality of zones is higher than the preset upper limit value, the pressure adjustment amount may be calculated so that the pressure of the air pocket 121 of the corresponding zone is lower than the preset upper limit value. In addition, in the zone where the pressure change amount of the plurality of zones is lower than the preset lower limit value, the pressure adjustment amount may be calculated so that the pressure of the air pocket 121 of the corresponding zone is higher than the preset lower limit value.

As described above, the mattress control unit 191 may adjust the air of the air pocket 121 according to the pressure adjustment amount calculated by the pressure adjustment amount calculation unit 197.

Specifically, the mattress control unit 191 discharges the air of the air pocket 121 according to the pressure adjustment amount calculated by the pressure adjustment amount calculation unit 197 in a region where the pressure change amount of the plurality of zones is higher than the preset upper limit value. Can be controlled. In addition, the control unit may control the air supply to the air pocket 121 according to the pressure adjustment amount calculated by the pressure adjustment amount calculation unit 197 in the zone where the pressure change amount is lowered below the preset lower limit value among the plurality of zones.

For example, depending on the posture of the user, a difference in pressure applied to each zone of the air mattress 10 may occur. For example, when the load of the user is concentrated in the third zone 121-3 and the pressure in the third zone 121-3 is higher than the preset upper limit value, the air in the air pocket 121 of the corresponding zone is discharged. The pressure of the third zone 121-3 may be adjusted to be lower than the preset upper limit.

When the snoring determination unit 198 detects noise in the microphone 18, the amount of change in the pressure of the air pocket 121 during the preset time range T4 based on the noise detection time T3 at which the noise is detected is determined. By checking the average change amount, it is possible to detect whether the user is snoring.

Specifically, when noise is detected in the microphone 18, when the average change amount of the pressure change amount calculated during the preset range time T4 from the noise detection time point T3 is within the preset range D, the snoring state is recognized. If the average change amount is less than or above the preset range D, it may be recognized as external noise.

9 is a view schematically showing a smart mattress system according to an embodiment of the present invention.

9, the smart mattress system 1 includes an air mattress 10, a user terminal 30, a server 50, and an air pillow 70.

The air mattress 10 includes the air pocket unit 12 described above, and the pressure of the air pocket 121 of the air pocket unit 12 is adjustable. Specifically, the pressure of the air pocket 121 may be adjusted for each zone divided into a plurality of areas in the air pocket unit 12 of the air mattress 10 according to setting values or user information set and input by the user.

In addition, one or more air pocket units 12 may be inserted into the frame 11. For example, two air pocket units 12 may be inserted inside the frame 11. Specifically, the first air pocket unit l2L may be disposed on the left side of the frame 11, and the second air pocket unit 12R may be disposed on the right side of the frame 11. The first air pocket unit 12L and the second air pocket unit 12R may be controlled through the control module 19, respectively.

The user terminal 30 may receive input from the user of setting values including initial pressure values, alarm settings, or the like, or user information including user body information such as a user's weight and height. The user terminal 30 transmits setting values or user information input from the user to the air mattress 10 or the air pillow 70. The user terminal 30 may be any one of a notebook computer, a mobile phone, and a mobile phone.

The server 50 may receive measurement data from the air mattress 10, analyze the sleep pattern and the sleep quality of the user, and transmit the analyzed sleep pattern and the sleep quality to the user terminal 30.

The air pillow 70 may be connected to the air mattress 10, the user terminal 30, and the server 50. Air pillow 70 is pressure adjustable. In particular, if the user's sleeping posture is determined according to the pressure measurement value measured by the air mattress 10, the air pillow 70 may be pressure adjusted accordingly.

Detailed description of the air mattress 10, the server 50 and the air pillow 70 will be described later.

10 is a block diagram showing the configuration of a server according to an embodiment of the present invention.

Referring to FIG. 10, the server 50 may include a server communication unit 51, a server memory unit 52, a sleep pattern analyzer 53, and a sleep quality analyzer 54.

The server 50 receives measurement data from the air mattress 10, analyzes the sleep pattern and the sleep quality of the user, and transmits the measured data to the user terminal 30.

The server communication unit 51 may communicate with the air mattress 10 and the user terminal 30. In detail, the measurement data may be received from the air mattress 10, and the analyzed sleep pattern information and sleep quality information may be transmitted to the user terminal 30.

The server memory unit 52 stores user's measurement data, sleep pattern information, and sleep quality information for each user.

The sleep pattern analyzer 53 may analyze the sleep time and the sleep posture based on the measured data. Specifically, the sleep time analysis may calculate a daily sleep time, weekly average sleep time, monthly average sleep time, etc. based on the sleep time data received from the sleep time measuring unit 194.

In addition, the sleep pattern analyzer 53 may measure each zone where the pressure is increased by the pressure sensor 17 to determine and analyze the sleeping posture of the user. For example, when the amount of change in pressure in the first zone 121-1 is greater than the amount of change in the other zone, it may be determined that the user is lying sideways. When the user is lying on the side, a relatively heavy load is applied to the first region 121-1 of the shoulder portion, and less load is applied to the second region 121-2 of the waist portion.

In addition, when the pressure change amount of the third zone 121-3 is greater than the pressure change amount of the other zones, it may be determined that the user is lying on his back. If a lot of load is applied to the entirety of the third region 121-3, which is located at the hip portion, it can be seen that the user is lying down.

In addition, the load is driven into the first zone 121-1 and the second zone 121-2, or the load is driven into the second zone 121-2 and the third zone 121-3. If the load is concentrated in the area, the user may determine that it is crouching.

In this way, the posture of the user can be grasped according to the load distribution for each zone. Therefore, the sleep pattern analyzer 53 may analyze the main sleep posture and the time for each sleep posture taken by the user during the sleep time.

Specifically, during the user's sleep time, through the change in the pressure of the air pocket 121 for each zone, to determine the user's sleep posture, including lying sideways, lying on the back, lying down, squat posture, etc. Can be. In addition, by identifying each posture holding time, it is possible to analyze the main sleep posture and the time for each sleep posture mainly taken by the user during the sleep time.

The sleep quality analyzer 54 may classify the sleep state of the user into a deep sleep state, a shallow sleep state, and a waking state, determine and analyze the sleep state based on the measured data, and score the sleep quality.

The sleep quality analyzer 54 may enter into a deep sleep state (NREM sleep: nonrapid eye movement sleep) when the average change amount (that is, average change rate) of the pressure change amount of the entire area of the air pocket 121 is a preset range A. You can judge. In addition, when the average change amount of the pressure change amount of the entire area of the air pocket unit 12 is a predetermined range B, the user may determine that the user is in a shallow sleep state (REM sleep: rapid eye movement sleep). In addition, when the average change amount of the pressure change amount of the entire area of the air pocket unit 12 is a predetermined range C, it may be determined that the user is awake.

That is, the sleep quality analyzer 54 assigns a score to each of A, B and C according to the average change amount of the pressure change amount of the entire area of the air pocket unit 12 and calculates an average value according to the sleep time. The quality of sleep can be scored. Specifically, in the preset range A, the score a may be assigned, in the preset range B, the score b may be assigned, and in the preset range C, the score c may be assigned.

For example, the sleep quality analysis unit 54 determines that the average change in pressure is in a deep sleep state when the pressure is 10% or less, and when the average change in pressure is in excess of 10% and 30% or less, it is determined that the sleep quality is shallow. In the case where the average change in pressure is more than 30%, it can be judged that it is in awake state. In addition, 10 points can be given in a deep sleep state, 5 points can be given in a shallow sleep state, and 1 point can be given in a waking state. In this way, a score may be assigned to each step, the scores of the states over time may be summed, and the sleep quality score may be calculated by dividing by the total time.

11 illustrates a process of scoring sleep quality according to an embodiment of the present invention. FIG. 11A illustrates a graph of pressure change rate over time in order to score sleep quality according to an embodiment of the present invention, and FIG. 11B illustrates an equation for scoring sleep quality according to FIG. 11A.

11A and 11B, the sleep quality analyzer 54 shows the average change amount of the pressure change amount of the entire area of the air pocket unit 12 measured by the pressure change rate measurer 19 over time. For example, the average amount of change in pressure can be represented at one hour intervals.

11A illustrates, as an example, a rate of change of the pressure of the air pocket unit 12 measured during the sleep time, taking the sleep time of the user from 12 am to 9 am as an example.

From 12 o'clock to 2 o'clock when the user starts to sleep, it can be determined that the user is awake since the average change in pressure is greater than the preset range C.

From 2 o'clock to 3 o'clock, the average change in pressure is within a preset range B, and the user may be determined to have a shallow sleep state.

Thereafter, between 3 and 7 o'clock, the average change in pressure is less than or equal to the preset range A, and it may be determined that the user is in a deep sleep state.

From 7 o'clock to 9 o'clock, when the average change in pressure gradually increases from the preset range B to C, it can be seen that the user gradually wakes up from sleep.

In summary, the time measured by the average range of pressure in the preset range A is 4 hours from 3 to 7 hours, and the time measured by the preset range B is 1 to 3 hours and 7 to 8 hours. The time measured in the preset range C is 2 hours from 12 to 1 hour and 8 to 9 hours.

By assigning scores a, b, and c to each of the preset ranges A, B, and C, sleep quality may be scored. High scores can be given for deep sleep, low scores for waking, and intermediate scores for shallow sleep.

FIG. 11B is a score of sleep quality through a score assigned to a preset range.

Referring to FIG. 11B, an average score of sleep quality may be obtained by multiplying a score corresponding to each sleep state by a time maintaining each sleep state and dividing by the total time.

For example, multiply the deep sleep state score a measured in the preset range A by 4 hours of deep sleep time, multiply the deep sleep state score b measured in the preset range B by 3 hours of deep sleep time, Multiply the score c for deep sleep, measured in range C, by 2 hours of deep sleep. Then, the average score can be calculated by dividing by 9 hours, which is the total sleep time.

The preset range A may be assigned 10 points, the preset range B may be assigned 5 points, and the preset range C may be assigned 1 point. In this case, in the case of FIG. 13B, the sleep quality may be scored by dividing the sum of (10x5), (5x3), and (1x2) by 9, which is the total sleep time.

12 illustrates a setting screen of the user terminal according to an embodiment of the present invention, FIG. 13 illustrates a sleep quality score screen of the user terminal according to an embodiment of the present invention, and FIG. 14 illustrates an embodiment of the present invention. The sleep pattern analysis screen of the user terminal according to an example is shown.

Referring to FIG. 12, the user may manually adjust the pressure through the pressure adjusting menu x1. However, in FIG. 12, for example, the user manually adjusts the pressure through the pressure adjustment menu x1, but is not limited thereto. As described above, the pressure may be automatically adjusted by the configuration including the mattress control unit 191, the pressure adjustment amount calculation unit 197.

Through the left and right switching menus x2, the settings of the first air pocket unit l2L (see FIG. 9) disposed on the left side and the second air pocket unit 12R disposed on the right side can be switched.

Through the time setting menu x3, the user may set a use time of the air mattress 10, that is, a sleep time. However, the present invention is not limited to setting the sleep time, and may be automatically set according to the user's use time of the air mattress 10.

Through the user information input menu x4, the user may input a user's physical condition including a key, weight, and the like.

Referring to FIG. 13, the smart mattress system 1 may provide a score of sleep quality to a user through the user terminal 30. The total score is displayed so that the user can check his or her sleep quality, and the user's sleep state is graphed over time. In addition, the total sleep time, the sleep time in the deep sleep state, the sleep time in the shallow sleep state, and the sleep time in the awake state can be displayed.

Referring to FIG. 14, the smart mattress system 1 illustrates a screen on which a sleep pattern is provided to a user through the user terminal 30. To allow the user to check his or her sleep pattern, the total sleep time may be displayed and the time may be displayed for each sleep posture. For example, the user may display the time according to the posture of the user, such as lying down, lying down on the side, or curled down. Based on this, the posture of the user maintained for the most time may be displayed as the main sleep posture.

The air mattress initial pressure adjusting step S210 may adjust the initial pressure of the air mattress 10 based on the setting value or the user information transmitted in the information receiving step S100. For example, when the user sets the initial pressure value of the air mattress 10 to 50 pa through the user terminal 30, the pressure so that the pressure value of the air mattress 10 corresponds to 50 pa in the initial pressure adjusting step (S210). This can be adjusted.

Meanwhile, the user may input a pressure range for setting the strength of the air mattress 10 in the user terminal 30. For example, the pressure regulation range can be 1pa to 100pa. It can be divided into five ranges. The first range, the lowest pressure range, is from 1pa to 20pa. Subsequently, the second range may be classified into 21pa to 40pa, the third range from 41pa to 60pa, the fourth range from 61pa to 80pa, and finally the fifth range from 81pa to 100pa. The first range is the range where the pressure is lowest, and the strength of the air mattress 10 is low. Therefore, it is possible to implement a fluffy air mattress 10. On the contrary, the fifth range is the range where the pressure range is the highest, and the strength of the air mattress 10 is high, so that the air mattress 10 may be realized.

The air pillow initial pressure adjusting step 220 may also adjust the initial pressure of the air pillow 70 based on the set value or user information transmitted in the information receiving step S100, similar to the air mattress initial pressure adjusting step S210. .

However, the pillow pressure sensor unit 75 may measure the pressure of one or more air cells 72 formed on the air pillow 70, respectively. For example, when two air cells 72 are formed, the pressure of each of the two air cells 72 may be measured. In other words, in the pillow pressure measuring step S320, the pressure of each of the first air cell 72a and the second air cell 72b may be measured in real time through the pillow pressure sensor unit 75.

Using a pressure measurement value measured in real time in the pressure measurement step (S300), it may include a pressure change amount calculation step (S400) for calculating the pressure change amount of the air pocket 121 through the pressure change amount calculation unit 195. . Specifically, the pressure change amount calculation unit 195 calculates the pressure change amount of the air pocket 121 through the air pocket 121 pressure measurement value of the air mattress 10 measured in real time in the mattress pressure measurement step S310. can do.

In addition, in the pressure measurement step (S300), the use area determination unit 196 may determine the user's body condition or upper body lower body position according to the pressure change amount of the air pocket 121. In addition, the use area determiner 196 may divide the air pocket unit 12 into a plurality of zones according to the determined body condition and upper body lower body position.

After the pressure change amount calculating step S400, the sleep posture determining step S410 and the sleep state determining step S420 may be performed.

In the sleep posture determination step S410, the user's sleep posture may be determined based on the pressure change amount of the air pocket 121 calculated in the pressure change amount calculation step S400. As described above, the air mattress 10 includes a plurality of zones including a first zone 121-1, a second zone 121-2, a third zone 121-3, and a fourth zone 121-4. It is divided into zones, and the sleeping posture of the user can be determined according to the pressure change amount of each zone. For example, when the pressure change amount of the first zone 121-1 is greater than the pressure change amount of the other zone, it may be determined to be lying sideways, and the pressure change amount of the third zone 121-3 is different from the pressure of the other zone. If it is larger than the change amount, it can be judged by lying on its back.

The sleep state determination step S420 may determine whether the sleep state of use is a deep sleep state (NREM sleep) or a shallow sleep state (REM sleep) based on the average change amount of the pressure change amount calculated in the pressure change amount calculation step S400. have.

In the sleep state determination step (S420), the mattress control unit 191 may determine that the average change amount of the pressure change amount of the air pocket 121 calculated in the pressure change amount calculation step (S400) is a preset range A. NREM sleep). In addition, when the average change amount of the pressure change amount of the air pocket 121 is a preset range B, the mattress control unit 191 may determine that the user is in a shallow sleep state (REM sleep).

A pressure adjustment amount calculating step S500 for calculating pressure adjustment amounts of the air pocket 121 and the air cell 72 based on the pressure change amount calculated by the pressure adjustment amount calculation unit 197 may be included.

The pressure adjustment amount calculation step S500 may include a mattress pressure adjustment amount calculation step S510 and a pillow pressure adjustment amount calculation step S520.

In the pressure adjustment amount calculation step S500, the pressure adjustment amount may be determined according to the sleep attitude determined in the sleep posture determination step S410.

The mattress pressure adjustment amount calculating step S510 may calculate the pressure adjustment amount of the air pocket 121 according to the sleeping posture of the user determined in the sleep posture determination step S410.

For example, when it is determined that the user is lying on his back, the load of the user may be concentrated in the third zone 121-3 so that the pressure of the third zone 121-3 may be higher than the preset upper limit. In this case, the pressure adjustment amount may be calculated such that the pressure of the air pocket 121 of the third zone 121-3 is lower than the preset upper limit.

The pillow pressure adjustment amount calculating step S520 may calculate the pressure adjustment amount of the air cell 72 according to the sleeping posture of the user determined in the sleep posture determination step S410.

For example, when it is determined that the user is lying on the side, a load is further applied to the first air cell 72a positioned at the head of the user and is applied to the second air cell 72b positioned at the neck of the user. Less load may be applied. Accordingly, air may be introduced into the first air cell 72a positioned at the head of the user, and air may be discharged from the second air cell 72b positioned at the neck of the user. Alternatively, air may be introduced into the first air cell 72a by reducing the air inflow amount of the second air cell 72b as compared with the air inflow amount. Therefore, when the user is lying on the side, it is possible to prevent the pressure is applied to the neck. In other words, the air inflow amount and the air discharge amount may be determined according to the loads applied to the first air cell 72a and the second air cell 72b.

It may include a pressure adjustment step (S600) for controlling the pressure of the air pocket 121 and the air cell 72, respectively, in accordance with the pressure adjustment amount calculated by the pressure adjustment amount calculation unit 197.

The pressure adjusting step S600 may include a mattress pressure adjusting step S610 and a pillow pressure adjusting step S620. For example, in the pressure adjusting step S600, the pressure may be adjusted according to the sleeping posture determined in the sleeping posture determining step S410.

Mattress pressure adjustment step (S610) may adjust the pressure of the air pocket 121 according to the pressure adjustment amount calculated in the mattress pressure adjustment amount calculation step (S510).

The pillow pressure adjusting step S620 may adjust the pressure of the air cell 72 according to the pressure adjusting amount calculated in the pillow pressure adjusting amount calculating step S520.

As described above, when it is determined that the user is lying sideways in the sleep position determination step (S410), the pillow control unit 77 of the air pillow 70 is located in the first air cell 72a located at the head of the user. It can be controlled to introduce air. In addition, when it is determined that the user is lying on his back in the sleep posture determination step (S410), the pillow control unit 77 of the air pillow 70 supplies air to the second air cell 72b positioned at the user's neck. Can be controlled to inflow.

The server 50 receives the measurement data including the pressure measurement value, the pressure change amount, the sleep time, and the pressure control amount for each zone from the air mattress 10, and analyzes the sleep information and the sleep quality of the user. It may include (S700).

The sleep information analysis step S700 may include a sleep pattern analysis step S710 in which the server 50 analyzes a sleep posture and a sleep time based on the measurement data transmitted from the air mattress 10.

In the sleep pattern analysis step (S710), the sleep pattern analyzer 53 measures each zone in which pressure is increased by the pressure sensor 17 to determine a sleeping posture of the user, but the first zone 121-1 is measured. If the amount of change in pressure is greater than the amount of change in the other zone, it may be determined that the user is lying sideways. In addition, when the pressure change amount of the third zone 121-3 is greater than the pressure change amount of the other zones, it may be determined that the user is lying on his back. The main sleep posture taken by the user during the sleep time and the time taken by the sleep posture may be analyzed to provide the user with sleep pattern information.

The server 50 divides the user's sleep state into a deep sleep state, a shallow sleep state, and a waking state based on the measurement data transmitted from the air mattress 10, and determines the sleep state based on the measured data. In operation S730, a sleep quality analysis step of analyzing sleep quality may be included.

The method may include an information providing step (S800) of transmitting sleep information of the user analyzed by the server 50 to the user terminal 30 to provide sleep information to the user.

During the user's sleep time, the snoring detection step of detecting whether the snoring may include a step (S900).

Snoring detection step (S900) may include a noise detection step (S910), snoring status check step (S920) and snoring stop step (S930).

In the noise detection step S910, noise may be detected through the microphone 23.

In the snoring state checking step (S920), when the noise is detected in the noise detecting step (S910), the average change amount of the pressure change amount calculated during the preset time range (T4) from the noise detection time point (T3) where the noise occurs is the preset range. Snoring status can be checked by checking if it is within D.

If the average change in the pressure change is within the preset range D, the snoring is recognized as a state, and if the average change in the pressure change is less than or above the preset range D, it may be recognized as external noise.

The preset range D may be a range in which the user can determine that the user is in the sleep state while using the bed. The minimum value of the preset range D may be determined by the minimum load applied when the user uses the bed. When the pressure change amount is lower than the minimum value of the preset range D, the user may not use the mattress. Therefore, when the user does not use the mattress, the sound sensed by the microphone 23 may be recognized as external noise.

The maximum value of the preset range D may be determined by the pressure change amount when the user moves to the maximum while in the sleep state. When the pressure change exceeds the maximum value of the preset range D, the user may use the mattress in an awake state rather than in a sleep state. Therefore, when the pressure change amount exceeds the preset range D, the noise detected by the microphone 23 may be recognized as external noise. For example, when a lot of user movement is detected, the detected noise may be determined as external noise, not a snoring sound of the user, such as a TV sound or a user's conversation sound.

For example, the preset range D may include a preset range A determined to be in a deep sleep state (NREM sleep) and a preset range B determined to be in a shallow sleep state (REM sleep).

In the snoring stop step (S930), if it is determined that the user is snoring in the snoring state check step (S920), by repeating the air inlet and air discharge of the air pocket 121 or the air cell 72 to apply vibration to the user As a result, the user may stop snoring by changing the user's deep sleep state (NREM sleep) to a shallow sleep state (REM sleep). For example, in the snoring stop step (S930), when the average change amount of the pressure change amount of the entire area of the air pocket 121 is a preset range A, the user may determine that the user is in a deep sleep (NREM sleep). . As such, when the average change amount of the pressure change amount of the entire area of the air pocket 121 is in the preset range B, the user may determine that the user is in a shallow sleep state (REM sleep).

When the user sets the alarm, it may include an alarm step (S1000) for waking the user's sleep state.

The alarm step S1000 may include an alarm setting step S1010, a sleep state checking step S1020, a sleep state switching step S1030, and an alarm generating step S1040.

In the alarm setting check step (S1010), in step S100 of receiving set value information, whether or not a user sets an alarm may be checked.

In the sleep state checking step (S1020), when the alarm setting is confirmed in the alarm setting checking step (S1010), the sleep state of the user is deep in the sleep state from the sleep state determination step (S430) before the preset alarm time (T5) from the alarm time. You can check whether it is (NREM sleep) or shallow sleep (REM sleep).

In the sleep state switching step S1030, when the user's sleep state checked in the sleep state checking step S1020 is a deep sleep state (NREM sleep), the air pocket 121 before the preset alarm time T5 from the alarm time. Alternatively, the sleep state of the user may be switched from a deep sleep state (NREM sleep) to a shallow sleep state (REM sleep) by adjusting the pressure of the air cell 72. In detail, the sleep state switching step S1030 may include a vibration generating step 1031 and a stretching generating step S1032.

In the vibration generating step S1031, the air inlet and the air outlet of the air pocket 121 or the air cell 72 are repeatedly supplied to the user in order to change the user's deep sleep state (NREM sleep) to the shallow sleep state (REM sleep). Vibration may be applied. Specifically, vibration may be generated by repeatedly introducing and discharging air of the plurality of air pockets 121 at the same time, or by repeatedly introducing and discharging air of the plurality of air cells 72 at the same time.

Alternatively, a stretching generation step S1032 may be included to change the user's deep sleep state NREM sleep to a shallow sleep state REM sleep. In the stretching generation step S1032, the air inflow and outflow of the air pocket 121 may be introduced and discharged in contrast between the respective zones to generate a stretch in the user's body. Alternatively, the air inlet and the air outlet of the air cell 72 may be introduced and discharged in contrast to the plurality of cells, respectively.

In the alarm generating step S1040, after the user's sleep state is switched to a shallow sleep state (REM sleep), the alarm may be generated at an alarm time received at the set value information receiving step S100.

On the other hand, if it is determined that the user is in a shallow sleep state (REM sleep) in the sleep state check step (S1020), it may be switched directly to the alarm generation step (S1040) without going through the sleep state switch step (S1030). Therefore, when it is determined that the user is in a shallow sleep state (REM sleep), an alarm may be immediately generated at a preset alarm time T5. However, the present invention is not limited thereto, and even when the user is determined to be in a shallow sleep state (REM sleep), the user may be switched to the alarm generation step S1040 after the sleep state switching step S1030.

When the pressure measurement value measured by the pressure sensor 17 of the air mattress 10 becomes 0, it is determined that the user has finished using the air mattress 10, and thus the operation of the smart mattress system 1 may be stopped. have.

However, even after the above operation process, if the pressure is continuously measured in the air mattress 10 may be repeated from the first step of receiving the set value information (S100).
