Description

A smart pillow that senses a head start during sleep

The present invention relates to a smart pillow, and more particularly, to a smart pillow that senses a referee in sleep.

The sleep surface does not react to the surrounding environment in appearance, and the normal sleeping state is a state in which sensation or reflection function is deteriorated.

The sleep is divided into five levels according to the depth of each step. It is shallow sleep 1, 2 stages, deep sleep 3, 4 stages, and dreaming REM sleeping phase. A shallow sleep is easy to wake because of the surrounding noise, light, etc., and deep sleep is difficult to break even if it is called from the side. It sleeps by repeating several steps in one cycle of five steps. Among these steps, sleeping during the first and second stages, which are shallow sleep, occurs mainly on the average and is repeated 20 ~ 30 times on average.

You can feel that the degree of fatigue recovery is different even if you spend the same time in your daily life. In this regard, we can see that the quality of sleep is more important than the amount of sleep, and busy modern people do not have enough sleep time, so it is necessary to improve the quality of sleep and recover the fatigue .

Currently, there are many ways to analyze the pattern of sleep in order to improve the quality of sleep. One example of this is the method of measuring the brain waves and analyzing the sleep pattern to improve the quality of sleep. However, there is a limitation that this method requires an EEG instrument.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in an effort to solve the above-mentioned problems, and provides a smart pillow that can measure the quality of sleeping after measuring the jumping in sleep.

According to an embodiment of the present invention, there is provided a pillow body comprising: a pillow body; A plurality of pressure sensing panels dispersedly disposed on the pillow body; A display unit disposed at one side of the pillow body to display an operation state thereof; And controlling the display unit to display the movement state of the head on the basis of the sensing signals sensed by the plurality of pressure sensing panels and to support real-time bidirectional communication with the external terminal to transmit the movement state of the head to the external terminal A smart pillow including a control unit is provided.

Each of the plurality of pressure sensing panels is constituted by a plurality of switches that are turned on or off by a pressure applied in a vertical direction, Respectively.

The control unit individually counts the number of times of pressure applied to the plurality of pressure sensing panels from the time when the pressure is sensed by at least one of the pressure sensing panels of the plurality of pressure sensing panels, And displays the image.

The control unit individually counts the number of times of pressure applied to the plurality of pressure sensing panels from the time when the pressure is sensed by at least one of the pressure sensing panels of the plurality of pressure sensing panels, And the number of counts accumulated to the present time is transmitted to the external terminal at the time when the pressure sensing of all the pressure sensing panels is released, and at the same time, the number of counts is reset.

The smart pillow according to the embodiment of the present invention can be easily used during sleeping in a general house, and it is possible to determine the quality of the sleeping because it is possible to grasp the degree of refereeing after measuring the sleepiness during sleeping.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order to facilitate a person skilled in the art to easily carry out the technical idea of the present invention.

1 is a graph showing a sleeping period.

Referring to FIG. 1, the sleep cycle of a person will be described in detail as follows.

A person's sleep cycle consists of various stages from sleep latency to RAM (REM) sleep.

Non-Rem The stage called sleep is when a person is deeply asleep and does not break even to a small sound or the like, and the brain which worked hard during the day breaks. These non-REM sleep stages can be divided into four stages.

Non-Rem Sleep Level 1 is the stage in which a person wakes from a wakefulness state to a sleepy state, which crosses the boundary between sleeping and consciousness and identifies weak sounds and generally accounts for 5% of the total sleeping time.

Next, the second phase of Non-Rem Sleep is the first step that can be called real sleep, a light sleep that is able to wake a sleeping person so hard. At this time, the person who wakes up is usually easy to say that he did not fall asleep, just slept or was thinking differently, and generally accounts for 50% of the total sleep time.

Next, Non-Rem Sleep Levels 3 and 4 are not only difficult to wake up in a slow state of the brain, but also can not keep up with their minds for a while even if they have been forced to wake. Experts also call this stage an inert sleep.

On the other hand, the Rem sleeping phase is a state in which the body relaxes easily, and the brain does not completely sleep and processes information or stores short-term memory into long-term memory. EEG is similar to when awake, with eyeballs moving rapidly, mostly dreaming at this stage, usually taking 20-25% of the total sleep.

Usually 7 hours, the Rem and the Non-Rem sleep cross four times. People with sleep disorders often see a pattern of sleep stages to treat. Typically, the ideal sleep is 80% of non-Rem sleep and 20% of Rem sleep.

The smart pillow 1 according to the embodiment of the present invention grasps the sleep pattern of a person in consideration of the sleep cycle of the person based on the sensing signal sensed by the plurality of pressure sensing panels 100. [

Fig. 2 is a conceptual diagram of a smart pillow 1 for detecting a referee in sleep according to an embodiment of the present invention, and Fig. 3 is a more detailed configuration diagram of the smart pillow 1 of Fig.

The smart pillow 1 according to the present embodiment includes only a simple structure for clearly explaining the technical idea to be proposed.

Referring to FIG. 1, the smart pillow 1 includes a pillow body 10, a plurality of pressure sensing panels 100, a display unit 200, a controller 300, and an external terminal 20.

The detailed configuration and main operation of the smart pillow 1 configured as described above will be described below.

The pillow body 10 can be composed of soft fabric materials such as cotton, synthetic fibers and memory foam, or materials favorable to ventilation such as bamboo, plastic, and the like.

A plurality of pressure sensing panels 100 are dispersedly disposed on the pillow body 10. In the present embodiment, a total of five pressure sensing panels 100 are disposed.

That is, in this embodiment, the pillow body 10 is provided with the first pressure sensing panel L1, the second pressure sensing panel L2, the third pressure sensing panel M, the fourth pressure sensing panel R1, The pressure sensing panel R2 is arranged in the horizontal direction.

The plurality of pressure sensors 300 are dispersedly disposed on the pillow body 100 to sense the pressure at the corresponding position. That is, the plurality of pressure sensors 300 determine the position of the user's head by sensing the weight of the user's head using the smart pillow 10.

In the present embodiment, the first pressure sensing panel L1, the second pressure sensing panel L2, the third pressure sensing panel M, the fourth pressure sensing panel R1, and the fifth pressure sensing panel R2 are ,

(TURN ON) or a turn-OFF (TURN OFF) state by a pressure applied in the vertical direction, and the plurality of switches are connected in parallel with each other.

For example, in the case of the third pressure sensing panel M arranged in the middle area, a total of three switches are arranged in a triangular shape. Accordingly, when a pressure is applied in the vertical direction by the head of a person, at least one of the three switches is turned on to detect the position of the head of the person.

That is, since the three switches are connected in parallel to each other, it is possible to detect that the pressure is applied to the third pressure sensing panel M even if any one of them is turned on. The number of switches may be adjusted according to the embodiment, and a switch which is turned on by different pressure depending on the arrangement position may be used.

Meanwhile, in the embodiment of the present invention, the third pressure sensing panel M disposed in the middle area may be used as a main power switch. That is, the pressure sensing operation starts from the time when the pressure is sensed on the third pressure sensing panel M, and when the pressure of all the pressure sensing panels 100 is released, the main power is automatically shut off do. Although not shown in the figure, the pillow body 10 is formed with an area where a battery can be attached, and the smart pillow 1 is preferably configured to operate using power from the battery.

The display unit 200 is disposed on one side of the pillow body 10 to indicate the operation state thereof.

A flat panel display such as an LCD panel may be used for the display unit 200, and a flexible display may be used so that a person can reduce a foreign object when the head is connected.

The control unit 300 controls the display unit 200 to display the movement state of the head on the basis of the sensing signals sensed by the plurality of pressure sensing panels 100 and supports real-time bidirectional communication with the external terminal 20 And transmits the motion state of the head to the external terminal 20.

The control unit 500 supports real-time bidirectional communication with the external terminal 20 using a wireless communication module, that is, a Bluetooth module.

The external terminal 20 collectively refers to a device that a user can use while being portable, such as a mobile phone, a smart phone, a smart pad, and a smart watch. In the present exemplary embodiment, the external terminal 20 is assumed to be an external terminal configured as a smart phone.

The control unit 300 individually counts the number of pressures applied to the plurality of pressure sensing panels 100 from the time when the pressure is sensed by at least one of the plurality of pressure sensing panels 100, (200).

For reference, the third pressure sensing panel M disposed in the middle area may be used as the main power switch, and the pressure sensing panel may be used to sense the pressure from the time when the pressure is sensed on one of the pressure sensing panels 100 The main power may be automatically shut off when a certain period of time has elapsed from when the operation starts and the pressure of all the pressure sensing panels 100 is released.

In addition, the control unit 300 may individually count the number of times of pressure applied to the plurality of pressure sensing panels 100 from the time when the pressure is sensed by at least one of the pressure sensing panels 100, Counted and displayed on the display unit 200,

It may be operable to transmit the number of counts accumulated up to the present time to the external terminal 20 at the time when the pressure sensing of all the pressure sensing panels 100 is released, and at the same time to reset the counting number.

The display unit 200 is provided with a first pressure sensing panel L1, a second pressure sensing panel L2, a third pressure sensing panel M, a fourth pressure sensing panel R1, The number of times the pressure is applied to the user R2 is displayed, so that the user's sleep pattern can be inferred based on the number of times.

The user can ascertain the degree to which the user is turned off while sleeping so that the problem of the sleep pattern can be grasped. And you can improve your sleep rhythm. If you take a good night's sleep by improving your sleep rhythm, it will be effective in strengthening your immune system and preventing aging. If you sleep better than anything else, you will be able to recover fatigue accumulated in your social life and help you improve your concentration. .

The external terminal 20 is provided with a sleep pattern management application. The application stores the sleep pattern information transmitted from the control unit 300 (the first pressure sensing panel L1, the second pressure sensing panel L2, The number of times of pressure of the panel M, the fourth pressure sensing panel Rl and the fifth pressure sensing panel R2) is stored in a database for each user. Therefore, even if the data stored in the controller 300 is reset, the sleep pattern of the user can be confirmed through the sleep pattern information stored in the application.

For reference, the control unit 300 includes a first pressure sensing panel L1, a second pressure sensing panel L2, a third pressure sensing panel M, a fourth pressure sensing panel R1, R2 to the external terminal 20 in real time,

When the sensing signal is transmitted in real time in this way, the application of the external terminal 20 can simultaneously store the position where the pressure is sensed and the time information at that time, and display the position where the pressure is applied over time in the form of a graph.

Although not shown in the drawing, the pillow body 10 is provided with a power supply circuit for supplying driving power to the internal circuit. The power supply circuit may be configured to receive driving power from the outside, and may be configured to receive driving power from an internal battery. At this time, the controller 300 may switch to a normal mode, a power down mode, and a deep power down mode to reduce internal power consumption.

The normal mode refers to a general operation mode in which driving power is supplied to all internal modules of the controller 300. The power down mode is a mode in which the driving power is supplied only to a part of the internal circuit of the controller 300 Quot; power saving mode "

In addition, the deep power down mode refers to an ultra low power mode in which driving power is supplied only to an internal circuit of the controller 300, which can guarantee only a minimum operation. For reference, switching from deep power down mode and power down mode to normal mode is performed by an interrupt signal according to the occurrence of an internal circuit event, Mode to Deep Power Down Mode and Power Down Mode can be performed when certain conditions are met.

The control unit 300 may supply the plurality of pressure sensing panels 100 and the display unit 200 in a normal mode, a deep power down mode, and a power down mode, Respectively. That is, the control unit 300 performs a power control function such as shutting off or supplying the driving power supplied to the corresponding element when switching to each mode.

The switching method and the internal operation of the normal mode, the power down mode and the deep power down mode can be variously performed according to the configuration of the control unit 300, Can be achieved as follows.

First, the controller 300 stores the sensing signal in the normal mode, transmits the stored sensing signal to the external terminal 20, and periodically enters the power down mode to reduce power consumption . ≪ / RTI > At this time, the controller 300 automatically enters the power down mode after the set time without considering other conditions, and automatically enters the normal mode (Normal) after the set time even after entering the power down mode Mode. That is, the switching between the normal mode and the power-down mode is repeatedly performed in absolute time units.

Also, if the sensing signal is not updated for a predetermined time, the controller 300 may be configured to enter a power down mode to reduce power consumption. At this time, when the sensing signal is updated, the controller 300 switches to the normal mode, stores the updated sensing signal again, and transmits the updated sensing signal to the external terminal 20. That is, when the user is deeply awake and there is no movement, the sensing signal sensed by the plurality of pressure sensing panels 100 is not updated, and the same signal is maintained. At this time, the controller 300 enters a power down mode to reduce power consumption. When the user's motion is detected, the controller 300 switches back to the normal mode, stores the updated sensing signal, and transmits the sensed signal to the outside.

Also, if the sensing signal is not updated for a predetermined time, the controller 300 may be configured to enter a power down mode to reduce power consumption. The control unit 300 may be configured to enter a deep power down mode when the sensing signal is not updated for a certain period of time after entering the power down mode to further reduce power consumption . That is, the controller 300 turns off the internal wireless communication module in the power down mode to reduce power consumption. In addition, the control unit 300 turns off the internal module except the control module that is responsible for the plurality of pressure sensing panels 100 in the deep power down mode, thereby further reducing power consumption. At this time, the controller 300 may be configured to switch to the normal mode when a sensing signal is sensed in the plurality of pressure sensing panels 100, that is, when the motion of the user is sensed.

Finally, when the controller 300 receives the alarm pattern (morning call) from the external terminal 20 in the power down mode and the deep power down mode, the control unit 300 automatically sets the normal mode Mode). That is, the operation mode of the smart pillow can be controlled by setting the external terminal 20.

The smart pillow 1 according to the present embodiment is switched to the normal mode, the power-down mode and the deep power-down mode according to the operating conditions, so that the power consumption can be reduced. Further, since the smart pillow 1 turns off the electromagnetic wave and electromagnetic wave generating modules such as the wireless communication module in the power down mode and the deep power down mode, the smart pillow 1 generates electromagnetic waves and electromagnetic waves that can be absorbed by the user's body Can be reduced.

The smart pillow according to the embodiment of the present invention can be easily used during sleeping in a general house, and it is possible to determine the quality of the sleeping because it is possible to grasp the degree of refereeing after measuring the sleepiness during sleeping.

Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive.
