Among them, there is a need for a sleep service capable of controlling the user's sleep environment by measuring the user's sleep state.

In order to provide such a sleep service, a device for detecting sleep information to determine a user's sleep state is required. As a device for detecting the user's sleep information, a band device attached to the user's body is used.

However, such a pressure change detection method is still a factor that hinders the user's sleep because the user has a self-awareness of the measurement device or a sense of disparity in the measurement device.

In addition, since the pressure change detection method measures sleep information only at some locations where the user's body pressure is applied, there is a problem in that measurement accuracy is lowered and user convenience according to actual use is lowered.

Recently, in order to compensate for the problem of a pressure change detection method using a pressure sensor, a method of determining a sleep state by detecting a capacitance according to an approach of the user's body when the user's body is in contact has been attempted.

However, the electrostatic capacity detection method still has a problem of deteriorating reliability when determining a sleep state such as a user's heart rate and respiration rate.

Therefore, it is required to develop a sleep service providing system that can induce a good night's sleep by precisely controlling the user's sleep environment based on this, acquiring the user's sleep information and twisting information by accurately measuring the bio-signal according to the user's sleep in the future. Has become.

1 is a block diagram illustrating a sleep service providing system according to an embodiment of the present invention, and FIG. 2 is a schematic diagram illustrating a sleep service providing system according to an embodiment of the present invention.

As shown in FIGS. 1 and 2, the system for providing a sleep service of the present invention includes a sleep detection device 100 that provides sleep environment control information by sensing a user's sleep state through a plurality of sensors, and sleep environment control information. A sleep environment control device 200 that controls the sleep environment control device 300 based on the sleep environment control information received from the sleep environment control information received from the sleep environment control device 300, and the sleep environment control information received from the sleep detection device 100 according to the sleep environment control device 200 Can include.

Here, when a sleep service request is received, the sleep detection device 100 determines whether an object exists based on sensing signals sensed from a plurality of sensors, and if an object exists, determines whether the object is tossed based on the amount of change in the sensing signal. According to whether or not the object is tossed, sleep information is extracted from the sensing signal to obtain sleep information, or torsion information is obtained from the sensing signal, and sleep environment control information corresponding to the acquired sleep information and tossing information is obtained from the sleep environment control device. It can be transmitted to 200.

As shown in FIG. 2, the sleep sensing device 100 includes a sensing unit 110 that senses a user's sleep state through a plurality of sensors, a power supply unit 120 that applies power to the sensing unit 110, and a sleep environment control device. A communication unit (not shown) that is communicatively connected to 200, and a driving control unit (not shown) for controlling driving of the sensing unit 110, the power unit 120, and the communication unit may be included.

Here, the sensing unit 110 may include a sensor mat on which a plurality of sensors are disposed, an upper cover mat disposed on the sensor mat, and a lower cover mat disposed below the sensor mat.

In this case, the sensor mat may include a substrate and a plurality of sensors arranged in one direction with respect to the surface of the substrate.

As an example, the substrate may be an insulator, but is not limited thereto.

Further, the plurality of sensors may be fiber-type sensors having a serpentine type shape, but are not limited thereto.

In addition, each sensor may include a first electrode wire to which positive power is applied and a second electrode wire to which negative power is applied.

Here, between the adjacent first electrode wires and the second electrode wires are arranged apart to have a predetermined gap, and between adjacent first electrode wires or between adjacent second electrode wires, They can be arranged apart at a predetermined pitch.

For example, a gap between the first and second electrode wires adjacent to each other may be about 2 mm to about 80 mm.

The reason is that if the gap between the first and second electrode wires adjacent to each other is too wide, the number of electrode wires of the sensor decreases due to the limited size of the sensor mat, making it difficult to accurately measure the biosignal. This is because if the gap between the second electrode wires is too narrow, it may be difficult to accurately measure a biosignal due to signal crosstalk.

Accordingly, the gap between the first and second electrode wires adjacent to each other may vary according to the area of the substrate.

That is, the gap between the first and second electrode wires adjacent to each other may decrease as the area of the substrate increases.

In addition, as an example, a pitch between adjacent first electrode wires or between second electrode wires may be about 2 mm to about 30 mm.

The reason is that if the pitch between the first and second electrode wires adjacent to each other is too wide, the number of electrode wires of the sensor decreases due to the limited size of the sensor mat, making it difficult to accurately measure the biosignal. This is because if the pitch between the second electrode wires is too narrow, it may be difficult to accurately measure a biosignal due to signal crosstalk.

Accordingly, the pitch between the first wires adjacent to each other and the pitch between the second electrode wires may vary depending on the area of the substrate.

That is, the pitch between the first wires adjacent to each other and the pitch between the second electrode wires may decrease as the area of the substrate increases.

In addition, the number of first and second electrode wires may vary depending on the area of the substrate.

That is, the number of first and second electrode wires may increase as the area of the substrate increases.

In addition, the plurality of sensors may include a first sensor group in which a plurality of sensors are disposed adjacent to a first area of the substrate, and a second sensor group in which a plurality of sensors are disposed adjacent to a second area of the substrate. .

In this case, the first distance between the first sensor group and the second sensor group may be closer than the second distance and the third distance.

In addition, the second distance and the third distance may be the same.

In addition, the first and second sensor groups include a plurality of sensors, and one end of each sensor may be electrically connected to a wire to which power is applied.

Here, the wiring may be disposed in the edge region of the substrate.

As an example, a wire connected to a sensor of a first sensor group and a wire connected to a sensor of a second sensor group may be disposed in an edge region of one side of the substrate.

Here, the arrangement direction of the wires connected to the sensors of the first sensor group and the arrangement direction of the wires connected to the sensors of the second sensor group may be the same direction.

In this case, the wiring connected to the sensor of the first sensor group and the wiring connected to the sensor of the second sensor group may be electrically connected to one and the same driving control unit.

As another example, a wire connected to the sensor of the first sensor group may be disposed on one edge region of the substrate, and a wire connected to the sensor of the second sensor group may be disposed on the other edge region of the substrate.

Here, the arrangement direction of the wires connected to the sensors of the first sensor group and the arrangement direction of the wires connected to the sensors of the second sensor group may be the same direction.

In this case, the wiring connected to the sensor of the first sensor group and the wiring connected to the sensor of the second sensor group may be electrically connected to one and the same driving control unit.

As another example, a wire connected to the sensor of the first sensor group and a wire connected to the sensor of the second sensor group may be disposed in an edge region of one side of the substrate.

Here, the arrangement direction of the wires connected to the sensors of the first sensor group and the arrangement direction of the wires connected to the sensors of the second sensor group may be opposite to each other.

In this case, the wires connected to the sensors of the first sensor group and the wires connected to the sensors of the second sensor group may be electrically connected to different driving control units, respectively.

As another example, a wire connected to the sensor of the first sensor group may be disposed on one edge region of the substrate, and a wire connected to the sensor of the second sensor group may be disposed on the other edge region of the substrate.

Here, the arrangement direction of the wires connected to the sensors of the first sensor group and the arrangement direction of the wires connected to the sensors of the second sensor group may be opposite to each other.

In this case, the wires connected to the sensors of the first sensor group and the wires connected to the sensors of the second sensor group may be electrically connected to different driving control units, respectively.

Also, a temperature sensor 150 may be disposed between the first sensor group and the second sensor group.

Here, the temperature sensor 150 may be disposed in the central region of the substrate.

In this case, the temperature sensor 150 may be electrically connected to a wire to which power is applied.

As an example, the arrangement direction of the wires connected to the temperature sensor 150 may be the same as the arrangement direction of the wires connected to the sensors of the first sensor group and the arrangement direction of the wires connected to the sensors of the second sensor group. have.

As another example, the arrangement direction of the wiring connected to the temperature sensor 150 is a direction different from the arrangement direction of the wiring connected to the sensor of the first sensor group and the arrangement direction of the wiring connected to the sensor of the second sensor group. May be.

In addition, the wires connected to the temperature sensor 150 may be disposed together at one edge region of the substrate on which the wires connected to the sensors of the first sensor group and the wires connected to the sensors of the second sensor group are disposed.

In some cases, the wiring connected to the temperature sensor 150 is the other side edge of the board excluding the area on one side of the board on which the wiring connected to the sensor of the first sensor group and the wire connected to the sensor of the second sensor group are disposed. It can also be placed in an area.

In addition, the number of sensors included in the first sensor group and the number of sensors included in the second sensor group may be the same.

As an example, the number of sensors included in the first sensor group and the number of sensors included in the second sensor group may be at least two, respectively, but are not limited thereto.

Also, the number of sensors included in the first sensor group and the number of sensors included in the second sensor group may be different from each other.

For example, the number of sensors included in the first sensor group may be greater than the number of sensors included in the second sensor group.

For example, the first sensor group may include a first sensor disposed on one side of a first area of the substrate, a first wiring electrically connected to an end of the first sensor to apply power to the first sensor, and adjacent to the first sensor. A second sensor disposed on the other side of the first region of the substrate, and a second wire electrically connected to the end of the second sensor to apply power to the second sensor, and the first and second wires The directions may be the same direction.

In addition, the second sensor group may include a third sensor disposed on one side of the second area of the substrate, a third wiring electrically connected to the end of the third sensor to apply power to the third sensor, and disposed adjacent to the third sensor. And a fourth sensor disposed on the other side of the second region of the substrate, and a fourth wire electrically connected to the end of the fourth sensor to apply power to the fourth sensor, and the arrangement direction of the third and fourth wires is , May be in the same direction as each other.

In addition, the area of the sensor mat may be smaller than the area of the upper cover mat and the area of the lower cover mat.

The reason is to increase the reliability of signal detection by protecting the sensor mat from being exposed to the outside.

In some cases, the area of the sensor mat may be the same as the area of the upper cover mat and the area of the lower cover mat.

In addition, the thickness of the sensor mat may be thinner than the thickness of the upper cover mat and the thickness of the lower cover mat.

The reason is to increase signal sensitivity by minimizing the total mat thickness.

In some cases, the thickness of the upper cover mat may be thinner than that of the lower cover mat.

The reason is to increase the signal sensitivity capable of detecting a bio-signal of a person who comes into contact with the upper cover mat.

Next, when a sleep service request is received, the driving control unit controls the power supply unit 120 so that power is applied to the sensing unit 110 to drive the sensing unit 110, and based on the sensing signals sensed from the sensing unit 110 It is possible to control the communication unit to acquire at least one of sleep information and tossing information corresponding to the user's sleep state, and to transmit sleep environment control information corresponding to the acquired sleep information and tossing information to the sleep environment control device 200 have.

FIG. 4 is a diagram illustrating a sensing unit of FIG. 3, and FIG. 5 is a diagram illustrating an arrangement of a sensor wire of the sensing unit.

As shown in FIG. 4, the sensing unit 110 includes a sensor mat 114 on which a plurality of sensors 114-2 are disposed, an upper cover mat 112 disposed on the sensor mat 114, and It may include a lower cover mat 116 disposed under the sensor mat 114.

In this case, the sensor mat 114 may include a substrate 114-1 and a plurality of sensors 1140-2 arranged in one direction with respect to the surface of the substrate 114-1.

For example, the substrate 114-1 may be an insulator, but is not limited thereto.

Further, the plurality of sensors 114-1 may be fiber-type sensors having a serpentine type shape, but are not limited thereto.

Here, the fibrous sensor material may include silicone, PVC, teflon, nylon, etc., but is not limited thereto.

In addition, the area of the sensor mat 114 may be smaller than the area of the upper cover mat 112 and the area of the lower cover mat 116.

The reason is to increase the reliability of signal detection by protecting the sensor mat 114 from being exposed to the outside.

In some cases, the area of the sensor mat 114 may be the same as the area of the upper cover mat 112 and the area of the lower cover mat 116.

In addition, the thickness of the sensor mat 114 may be thinner than that of the upper cover mat 112 and the thickness of the lower cover mat 116.

The reason is to increase signal sensitivity by minimizing the total mat thickness.

In some cases, the thickness of the upper cover mat 112 may be thinner than the thickness of the lower cover mat 116.

The reason is to increase signal sensitivity capable of detecting a bio-signal of a person who comes into contact with the upper cover mat 112.

For example, a gap between the first and second electrode wires 1110 and 1120 adjacent to each other may be about 2 mm to about 80 mm.

The reason is that if the gap between the first and second electrode wires 1110 and 1120 adjacent to each other is too wide, the number of electrode wires of the sensor 114-2 is reduced due to the limited size of the sensor mat 114 This is because it is difficult to measure a biosignal, and if the gap between the first and second electrode wires 1110 and 1120 adjacent to each other is too narrow, it may be difficult to accurately measure the biosignal due to signal crosstalk.

Accordingly, the gap between the first and second electrode wires 1110 and 1120 adjacent to each other may vary depending on the area of the substrate 114-1.

That is, the gap between the first and second electrode wires 1110 and 1120 adjacent to each other may decrease as the area of the substrate 114-1 increases.

In addition, as an example, a pitch between the first electrode wires 1110 adjacent to each other or the pitch between the second electrode wires 1120 may be about 2 mm to about 30 mm.

The reason is that if the pitch between the first and second electrode wires 1110 and 1120 adjacent to each other is too wide, the number of electrode wires of the sensor 114-2 decreases due to the limited size of the sensor sheet 114. This is because it is difficult to accurately measure the biological signal, and if the pitch between the adjacent first and second electrode wires 1110 and 1120 is too narrow, it may be difficult to accurately measure the biological signal due to signal crosstalk.

Accordingly, the pitch between the first wires 1110 adjacent to each other and the pitch between the second electrode wires 1120 may vary according to the area of the substrate 114-1.

That is, the pitch between the first wires 1110 adjacent to each other and the pitch between the second electrode wires 1120 may decrease as the area of the substrate 114-1 increases.

In addition, the number of the first and second electrode wires 1110 and 1120 may vary depending on the area of the substrate 114-1.

That is, the number of the first and second electrode wires 1110 and 1120 may increase as the area of the substrate 114-1 increases.

As described above, according to the present invention, by accurately measuring a bio-signal according to the user's sleep, the user's sleep information and the torsion information are obtained, and based on this, the user's sleep environment can be precisely controlled to induce a good night's sleep.

The basic concept of the present invention is summarized as follows.

In the present invention, when a conductive fiber sensor is applied to a mat or a cover, the sensor is arranged to measure a biosignal even when lying on the mat, and a signal recognition device is installed in both the upper and lower directions of the mat to recognize the signal. It can be composed of.

In addition, according to the present invention, in order to measure a bio-signal, capacitance according to a distance between a sensor and a body must be measured.

To measure this capacitance, two conductors with different poles are required. The gap between the conductors of the other poles is defined as a gap, and the gap between the same conductors is defined as the pitch.

In some cases, the user makes direct contact with the sensor mat, but there may be a gap between the body and the sensor depending on a blanket or clothes, and the greater the gap, the less sensitive the biometric signal is.

Therefore, in the present invention, even when a gap occurs between the body and the fiber-type sensor, biosignal information such as heart rate can be arranged by adjusting the wire gap (Gap, Pitch) of the fiber-type sensor in order to determine the corrective capacity in a state of maximum sensitivity. have.

In addition, in the present invention, by applying a conductive fiber sensor to the mat, it is possible to measure a biosignal at any position of the bed, and a signal recognition device can be configured in a multi-channel mat so that signals of several contact points of the body can be simultaneously recognized. .

In addition, the present invention recognizes the shape and frequency of the sleeper's movement with the amount of change in the bio-signal on recognition in the multi-channel, and operates an air conditioner or controls air quality to create an environment for such a user's sleep. Lighting or music for

In addition, according to the present invention, it is possible to identify the exact shape and location of a user sleeping on the mat through the characteristics of signals emitted from the multi-channel and provide a service for a sound sleep.

The sleep sensing device of the present invention is configured in a form in which a fiber sensor is laid in the form of a bedding (mat) and may be connected to a driving module.

The driving module of the sleep sensing device is configured as a detachable type and may extract sleep information through biosignal information collected by the fiber-type sensor, and the power supply unit may supply power to the sleep sensing device.

In addition, the communication unit of the sleep sensing device can transmit the sleep information extracted from the driving module to an external computer or other device, and the IoT hub of the sleep environment control device is connected to the sleep sensing device and then the user's sleep through the sleep sensing device. It checks the state and performs actions to create a sound sleep environment according to the sleep state and movement.

Devices (air conditioners, boilers, air purifiers, sleep lights, and others) for a sleep environment control device are connected to the IoT hub and operate according to the instructions of the IoT hub according to the sleeper's condition to help the user sleep.

In addition, in this drawing, it is possible to set the configuration of the sensor wire and the gap (Gap, Pitch) between the two conductors for securing the maximum capacitance sensitivity.

The sensor wire detects the change in capacitance that occurs when the body approaches the body.To measure the capacitance, two conductors with different poles are required, the gap between the conductors of the other pole is a gap, and the gap between the same conductor is pitched. ) Can be defined.

The user can increase the distance from the sensor to about 0 to 16 mm by using a blanket over the sensor and clothes to wear.

In the present invention, when the corresponding material (silicon, PVC, teflon, nylon, etc.) of a fiber-type sensor is used, the gap and pitch at which the change in capacitance is maximized even when the distance between the sensor and the user is maximized. Configurable.

Here, as the gap between the two conductors is wide and the number of conductors increases, the amount of change in capacitance increases. However, since the size of the mat is limited, the number of conductors inevitably decreases when the gap is widened.

Therefore, the sensor wire of the present invention is configured so that the wires are connected in the form of +,-,-,+, and the gap is designed to be about 2nm to 80mm, and the pitch is designed to be about 2nm to 30mm. Even if the distance from the sensor increases, a capacitance with the highest signal sensitivity per unit area can be obtained.

In addition, according to the present invention, a sensor driving module may be configured with two or more channels so that the body can be detected from any part of the mat.

For example, according to the present invention, a driving module and a sensor wire may be configured as two channels so that a user can recognize a bio-signal at any position above or below the mat.

Here, the sensors for each of the two channels can be attached to the substrate so as to fit the corresponding gap and pitch.
