Description

  The present invention relates to a temporary sleep control device and a control method for controlling the quality of a user's temporary sleep, for example, based on the state of the main sleep at night of the user, and effectively relieving the user's sleepiness and recovering from fatigue by the temporary sleep. About.

  2. Description of the Related Art Conventionally, there is a technique aimed at relieving a user's drowsiness and recovering from fatigue by a short nap. For example, Patent Document 1 discloses a technique for controlling the quality of temporary sleep during temporary sleep of a vehicle occupant in a vehicle in order to effectively recover the fatigue of the vehicle occupant. Specifically, after the passenger falls asleep, the temporary sleep depth during the temporary sleep is measured, and the awakening time is determined according to the accumulated value of the temporary sleep depth. When it is time to wake up, a stimulus is given to the vehicle occupant from the stimulator to wake up from a temporary sleep. Thus, a technique for relieving drowsiness and recovering from fatigue even after a short sleep is described.

JP 2010-82377 A

  However, in the technique disclosed in Patent Document 1, for example, the sleep information is not coordinated with sleep information in the nighttime sleep (main sleep) of the previous day, and the depth of temporary sleep is measured based only on information during temporary sleep. A temporary sleeping time is determined. Usually, it is known that temporary sleep and nighttime sleep have a deep relationship. If the nap time is too long, you may not be able to sleep at night. If this happens, daytime activities on the next day may be affected by lack of sleep. For this reason, in the technology disclosed in Patent Document 1 that is not linked to the sleep information at night, when taking into consideration the sleep at night on the previous day, the patient takes deep temporary sleep that is not necessary, and this comes next. It may adversely affect nighttime sleep and may also affect daytime activity of the next day.

  The present invention has been made in view of such circumstances, and it is assumed that there is no temporary influence on the next main sleep and the daytime activity of the next day. An object of the present invention is to provide a temporary sleep control device and a control method that can effectively eliminate sleepiness and recover from fatigue by sleeping.

  The temporary sleep control device according to claim 1, which has been made to solve the above-described problem, includes a first bedding in which a user takes a regular sleep, a second bedding in which the user takes a temporary sleep, and the first bedding. A first biological information detection unit that detects the first biological information vibration of the user who takes this sleep and outputs a first biological information signal, and detects the second biological information vibration of the user who takes a temporary sleep with the second bedding A second biological information detection unit that outputs a second biological information signal, a main sleep onset determination unit that determines the main sleep onset in the user's sleep based on the first biological information signal, and the main sleep Based on the first biological information signal after falling asleep, the main sleep depth calculation unit that calculates the main sleep depth of the main sleep, and the main sleep between the sleep start time and the awakening time of the main sleep The main sleep calculated by the depth calculator A depth cycle recording unit that records the sleep depth cycle in which the depth periodically increases and decreases, and the temporary sleep in the second bedding based on the main sleep depth cycle recorded by the depth cycle recording unit. The temporary nap sleep setting for determining the nap sleep in the nap based on the second biological information signal and the optimal nap depth setting unit that sets the nap depth of the nap that is optimal The temporary sleep depth calculated by the determination unit, the temporary sleep depth calculation unit that calculates the temporary sleep depth based on the second biological information signal after the nap sleep, and the temporary sleep depth calculation unit Is determined by the optimal temporary sleep depth determination unit that determines whether or not the optimal temporary sleep depth set by the optimal temporary sleep depth setting unit has been reached, and the temporary sleep sleep determination unit. Is determined, and the optimal temporary sleep depth determination unit Ri, when the user is determined to have reached the optimum temporary sleep depth, and a wake device for waking the user by applying a stimulus to the user.

  Thus, the optimal temporary sleep depth in temporary sleep is set based on the final sleep depth cycle of the final sleep performed before taking a temporary sleep. If it is determined that the sleep time is insufficient based on the main sleep depth cycle of the main sleep, the temporary sleep time is set to be longer, for example. If it is determined that the sleep time is sufficient based on the main sleep depth cycle of the main sleep, the temporary sleep time is set to be short. As a result, the night of the day after taking a nap does not prevent a person from sleeping because the nap time is too long. Also, there will be no temporary sleep time, and the person will not enter this sleep with severe fatigue. For this reason, in this sleep, sleep can be performed as usual, and fatigue is not carried over to the next day.

  In order to solve the above-described problem, a control method for a temporary sleep control device according to claim 8 includes a first bedding in which a user takes a main sleep, a second bedding in which the user takes a temporary sleep, and the first bedding. Detecting a first biological information vibration of the user taking the main sleep and outputting a first biological information signal, and detecting a second biological information vibration of the user taking the second bedding nap And a second biological information detection unit that outputs a second biological information signal, and a control method of the temporary sleep control device, wherein the sleep onset of the user in the main sleep based on the first biological information signal A sleep sleep determination step, a sleep depth calculation step of calculating a sleep depth of the sleep based on the first biological information signal after the sleep sleep, and a sleep sleep of the sleep sleep Between the start time and the awakening time And a depth cycle recording step for recording a main sleep depth cycle in which the main sleep depth calculated by the main sleep depth calculation step periodically increases and decreases, and the depth cycle recording step that is recorded in the depth cycle recording step. Based on the sleep depth cycle, when taking the temporary sleep with the second bedding, the optimal temporary sleep depth setting step for setting the temporary sleep depth of the temporary sleep that is optimal, and the second biological information signal A nap sleep determination step for determining nap sleep onset in the nap and a nap depth calculation step for calculating the nap depth based on the second biological information signal after the nap sleep sleep; Optimal temporary sleep depth determination that determines whether the temporary sleep depth calculated by the temporary sleep depth calculation unit has reached the optimal temporary sleep depth set in the optimal temporary sleep depth setting step The When the nap sleep is determined by the nap determination step and the optimal nap depth determination step determines that the user has reached the optimal nap depth, the awakening device An awakening device control step of stimulating the user to awaken the user. By such a control method, the same control as the temporary sleep control by the temporary sleep control apparatus demonstrated above can be performed.

It is a general view of the temporary sleep control apparatus of this embodiment. It is an example of a sleep determination formula. It is a graph showing an example of a person's book sleep depth cycle. It is the flowchart 1 which shows the action | operation of the temporary sleep chair ASSY of this embodiment. It is the flowchart 2 which shows the action | operation of the bed ASSY of this embodiment.

(Configuration of temporary sleep control device 100)
Below, the outline | summary of the temporary sleep control apparatus 100 which concerns on this embodiment is demonstrated using FIG. The temporary sleep control device 100 includes a bed ASSY 10, a temporary sleep chair ASSY 20, a device operation signal transmission device 30, a relay device 40, and a plurality of external devices 61, 62, 63, 64.

(Configuration of bed assembly 10)
The bed ASSY 10 includes a bed 11 (corresponding to a first bedding), a first biological information detection sensor 13 (corresponding to a first biological information detection unit), and a first control unit 15. The bed 11 is a bedding on which the user 1 sleeps to get tired of the day, particularly at night. In the present embodiment, sleep when the user 1 sleeps on the bed 11 is referred to as “main sleep” in order to distinguish it from “temporary sleep” described later. That is, in the present embodiment, the main sleep means sleep that the user 1 does not intend to wake up immediately like a temporary sleep described later, but takes a deep sleep at least beyond the range of the temporary sleep.

  However, the time zone in which the user 1 sleeps is not limited to nighttime. If the user has a night shift, this sleep is early morning or daytime. That is, there is no time zone limitation for this sleep. The bed 11 includes a mat 11a, a base portion 11b, and a leg portion 11c. The bed 11 is placed on the floor surface of the bedroom. The mat 11a is placed on the base 11b, and the user 1 lies on the mat 11a and sleeps.

  The first biological information detection sensor 13 detects first biological information vibration generated by at least one of body motion vibration, pulse, and brain waves, which is the first biological information of the user 1, and outputs a first biological information signal 13a. Sensor. In the present embodiment, the biological information is body motion vibration. In the present embodiment, the first biological information detection sensor 13 is provided in the bed 11, specifically, disposed in the mat 11 a. The first biological information detection sensor 13 may be arranged in any manner in the mat 11a as long as it can detect the body motion vibration of the user 1. The first biological information detection sensor 13 may be directly attached to the user 1 instead of in the mat 11a. Further, the first biological information detection sensor 13 may be provided at any position of the base part 11b and the leg part 11c on which the mat 11a is placed.

  The first control unit 15 performs overall control of the bed assembly 10. The first control unit 15 includes a main sleep / sleep determination unit 15a, a main sleep depth calculation unit 15b, a depth cycle recording unit 15c, and a first wireless communication unit 15d. The first control unit 15 is connected to the first biological information detection sensor 13 and acquires the first biological information signal 13 a from the first biological information detection sensor 13.

  The sleep / sleep / sleep determination unit 15a determines the sleep / sleep sleep in the user's 1 sleep based on the first biological information signal 13a. Specifically, the sleep / sleep / sleep determination unit 15a performs the sleep / sleep / sleep determination based on the body motion vibration of the user 1. Note that any method may be used for the determination of sleep onset. For example, the calculation may be performed by a method disclosed in Japanese Patent Application Laid-Open No. 2014-70766. That is, first, based on the first biological information signal 13a output from the first biological information detection sensor 13, the number of body movements per unit time of the user 1 lying on the mattress 11a is calculated. Based on the calculated number of body movements, the sleep state and the awake state are determined. Specifically, the number of fluctuations of the load applied to the first biological information detection sensor 13 is converted into the number of body movements, and the number of body movements is stored. Then, the number of body movements is converted into an index Z representing a sleep state from the sleep determination formula illustrated in FIG. If the index Z exceeds 0, it is determined that the user 1 is in an awake state. If the index Z is 0 or less, it is determined that the user 1 falls asleep and is in a sleep state.

  The main sleep depth calculation unit 15b calculates the main sleep depth, which is the sleep depth after the main sleep sleep after the user's "sleep main sleep sleep" is confirmed by the main sleep sleep determination unit 15a. To do. For example, the sleep depth calculation unit 15b calculates that the user 1 is at a deeper sleep depth as the body motion vibration of the user 1 per unit time is smaller. In addition, the method of calculating this sleep depth based on the biological information of the user 1 is publicly known as disclosed in JP 2002-291710 A, JP 2009-153550 A, JP 2011-67241 A, and the like. Since this is a technology, I will omit the explanation here. The depth cycle recording unit 15c is a recording unit that records “this sleep depth cycle” to be described later in a flash memory or the like.

  Here, a human “real sleep depth cycle” will be described with reference to FIG. 3. As shown in FIG. 3, a person's “real sleep depth cycle” is a “real sleep depth” that becomes shallower after the “real sleep depth” periodically becomes deeper, that is, increases / decreases after the person begins to fall asleep. Has a plurality of "s". As illustrated in FIG. 3, as the “main sleep depth” increases, the REM sleep moves from the first sleep depth to the fourth sleep depth in order. This sleep cycle varies depending on the person, and changes depending on the environment (room temperature, humidity, brightness) at the start of the person's sleep.

  In the final sleep cycle, a person becomes awake and the sleep depth becomes shallow. In some cases, as shown by a broken line in FIG. 3, a person may become awake during the main sleep because the main sleep depth becomes too shallow during the main sleep. In addition, as shown by a two-dot chain line in FIG. 3, in a scene where the sleep depth has to be reduced in the middle of the cycle of the sleep depth, the sleep depth cannot be reduced and becomes deep again. In some cases, an unstable state is formed. If the sleep state is such, sleepiness and fatigue may remain on the next day.

  In addition, about temporary sleep, it is more effective to recover the sleepiness cancellation and fatigue of the user 1 after awakening by staying up to the second sleep depth among the four stages of sleep depth from the experimental results so far. know. If you enter deep sleep beyond the second depth of sleep, you may experience symptoms such as sluggishness when you wake up from sleep, sleepiness, and no sleep at night. Therefore, in this embodiment, the optimal temporary sleep depth is set so as not to exceed the state up to the second sleep depth.

  Returning to the description of the first control unit 15 again. The depth cycle recording unit 15c is configured so that the main sleep depth calculated by the main sleep depth calculation unit 15b described above is cyclic as the time from the main sleep onset start time of the main sleep to the awakening time elapses. Record multiple “real sleep depth cycles” that increase or decrease.

  The first wireless communication unit 15 d wirelessly communicates with the relay device 40 and transmits “main sleep depth cycle” data to the second control unit 24 of the temporary sleep chair ASSY 20 via the relay device 40.

(Configuration of Temporary Sleeping Chair ASSY20)
Next, the temporary sleeping chair ASSY20 will be described. As shown in FIG. 1, the temporary sleep chair ASSY 20 includes a temporary sleep chair 21 (corresponding to a second bedding), a second biological information detection sensor 23 (corresponding to a second biological information detection unit), and a second control unit 24. . The second control unit 24 includes a state detection unit 24a, an optimal temporary sleep depth setting unit 24b, a temporary sleep onset determination unit 24c, a temporary sleep depth calculation unit 24d, an optimal temporary sleep depth determination unit 24e, and an awakening device control unit 24f. And a second wireless communication unit 24g. The second control unit 24 controls the temporary sleep chair ASSY 20 in an integrated manner.

  The temporary sleep chair 21 is a bedding (second bedding) in which the user 1 takes a temporary sleep. The temporary sleeping chair 21 (second bedding) includes a reclining mechanism (not shown) that controls the angle of the backrest portion by operating a motor (not shown). The temporary sleeping chair 21 (second bedding) includes a cushion portion 21a, a support base 21b, and a leg portion 21c that supports the support base 21b.

  The second biological information detection sensor 23 is the same as the first biological information detection sensor 13. The second biological information detection sensor 23 is different from the first biological information detection sensor 13 only in reference numerals, and thus detailed description thereof is omitted. As shown in FIG. 1, in the present embodiment, the second biological information detection sensor 23 is provided on the leg portion 21 c of the temporary sleeping chair 21. In the present embodiment, the second biological information detection sensor 23 detects body motion vibration that is one of the biological information of the user 1 transmitted to the legs 21c of the temporary sleeping chair 21. Note that the present invention is not limited to this mode, and the second biological information detection sensor 23 may be directly attached to the user 1 and / or provided in the backrest portion of the temporary sleep chair 21.

  The state detection unit 24a is provided in the bedroom where the bed 11 (first bedding) and the temporary sleeping chair 21 (second bedding) are arranged. The state detection unit 24a includes a thermometer, a hygrometer, and an illuminometer. The thermometer detects the room temperature. The hygrometer detects the humidity in the bedroom. The illuminometer detects the brightness of the room. The state detection unit 24 a (thermometer, hygrometer, and illuminometer) outputs detection data to the second control unit 24.

  Each external device 61, 62, 63, 64 is a device that shortens the time until the user 1 reaches a nap sleep by changing the state, and improves the quality of the nap of the user 1. It is. In the bedroom of the user 1, an air conditioner 61, a lighting device 62, and a curtain opening / closing device 63 attached to a window are arranged as external devices. A heater 64 is disposed on the backrest portion and the seating surface of the temporary sleeping chair 21. The heater 64 is a heater (heat exchanger) disposed on the temporary sleeping chair 21 that raises the temperature of the contact surface with the user 1. The external device 64 is not limited to a heater, and may be a cooler (heat exchanger) that lowers the temperature of the contact surface with the user 1. State changes such as temperature, humidity, brightness, etc. for shortening the time required for the user 1 to fall asleep after operating the external devices 61, 62, 63, 64 are optimal for each user. Is set. That is, the optimal room temperature, brightness, humidity, temperature of the temporary sleep chair 21 and the like for the user 1 to quickly go into a nap sleep are set for each user.

  The optimum temporary sleep depth setting unit 24b acquires the “main sleep depth cycle” data recorded by the depth cycle recording unit 15c. And based on "this sleep depth cycle" data, the optimal temporary sleep depth of the user 1 who takes a temporary sleep in the temporary sleep chair 21 (2nd bedding) is set. Specifically, if the total sleep time is sufficient in the “main sleep depth cycle” and the waveform of the “main sleep depth cycle” has no problems such as awakening or unstable parts, In the optimum nap depth setting unit 24b, after determining that the user 1 on the nap chair 21 has fallen into a nap that is a nap of a nap, for example, a nap for 5 minutes. Set to do. Then, the determination of nap sleep onset is performed by the nap sleep detection unit 24c. The method is the same as that of the present sleep / sleep determination unit 15a. Further, the measurement of the elapsed time after nap sleep is performed by a timer (not shown) of the second control unit 24.

  Moreover, in the optimal temporary sleep depth setting part 24b, you may set so that the room temperature, humidity, brightness, etc. which were detected by the state detection part 24a may become optimal for the user's 1 temporary sleep falling asleep and a temporary sleep. For example, if the nap time is summer daytime, for example, a room temperature of 26 ° C. is set as the set temperature at the nap time. In addition, the closed state of the window curtain opening / closing device (external device 63) is set as a setting state during temporary sleep. Further, the lighting device (external device 62) sets the extinguished state to the set state during temporary sleep. The operations of these external devices 61, 62, 63 are performed wirelessly via the device operation signal transmission device 30 and the relay device 40.

  In addition, in the optimum temporary sleep depth setting unit 24b, from the acquired “real sleep depth cycle” data, the user 1 is awakened at night and the total sleep time is insufficient, or the user 1's When it is determined that the “real sleep depth cycle” does not have a clean waveform and exhibits an unstable waveform, for example, the user 1 on the temporary sleep chair 21 determines the optimum temporary sleep depth. After it is determined that the patient has fallen into a nap, the user is set to take a nap for 15 minutes, which is the maximum value.

  Here, the reason for setting the maximum time for temporary sleep to 15 minutes in the optimal temporary sleep depth setting unit 24b will be described. As described above, in order to eliminate drowsiness and recover from fatigue by temporary sleep, it is usually assumed that there are four stages from a sleep first depth indicating a shallow sleep state to a sleep fourth depth indicating a deep sleep state. It has been found that it is better to keep the sleep up to the second sleep depth among the sleep depths. Exceeding this may affect sleep at night, such as the inability to sleep. Further, it is known that when a nap is performed, the nap depth exceeds the first sleep depth relatively quickly after falling into a nap and reaches the second sleep depth. Furthermore, if it is within 15 minutes after nap sleep, it is known that there is a low risk of entering the third sleep depth. Therefore, in the present invention, the optimum temporary sleep depth is estimated and determined by the elapsed time after falling asleep. That is, the elapsed time after nap sleep is determined according to the acquired data of the present sleep depth cycle, with the upper limit being 15 minutes, which is an elapsed time that is reliably located within the second sleep depth. Thereby, it can determine easily and cost reduction can be achieved.

  And at this time, in order to further improve the quality of sleep and nap of the user 1 in the optimum nap depth setting unit 24b, the room temperature, brightness, humidity, and nap of the nap chair 21 detected by the state detection unit 24a You may control each external device 61, 62, 63, 64 so that temperature may become the optimal for the user's 1 nap sleep and a nap. Thereby, fatigue recovery can be achieved appropriately.

  Based on the second biometric information signal 23a output from the second biometric information detection sensor 23 generated by the body motion vibration of the user 1, the nap sleep / sleep determination unit 24c determines whether the user 1 has reached nap sleep. judge. Since the method is the same as that of the present sleep / sleep determination unit 15a, description thereof is omitted.

  The temporary sleep depth calculation unit 24d calculates the temporary sleep depth after falling asleep on the basis of the second biological information signal 23a output from the second biological information detection sensor 23 generated by the body motion vibration of the user 1. To do. Therefore, normally, after the nap sleep of the user 1 is determined by the nap sleep determination unit 24c, the temporary sleep depth may be measured by the same method as the measurement method of the sleep depth. . However, in fact, as described above, the relationship between temporary sleep depth and time is known in advance. Therefore, in the present embodiment, the temporary sleep depth is not actually measured in the temporary sleep depth calculation unit 24d. The nap depth calculator 24d measures the elapsed time after nap sleep.

  The optimal temporary sleep depth determination unit 24e determines whether or not the elapsed time measured by the temporary sleep depth calculation unit 24d has reached the time set by the optimal temporary sleep depth setting unit 24b. In other words, in the present embodiment, the optimal temporary sleep depth determination unit 24e estimates that the optimal temporary sleep depth has been reached when the set predetermined time has elapsed after falling asleep.

The awakening device control unit 24f is configured so that the optimal temporary sleep depth determination unit 24e determines the temporary sleep depth of the user 1 who is taking a temporary sleep with the temporary sleep chair 21 (second bedding), that is, the elapsed time is the optimal temporary sleep depth. When it is determined that the elapsed time set by the setting unit 24b is 5 minutes, the wake-up device 65 is activated to stimulate the user 1 to wake up the user 1. At this time, the awakening device 65 is an alarm provided on the temporary sleeping chair 21. The awakening device 65 may be any device. For example, the awakening device 65 may be a vibrator provided in the temporary sleeping chair 21. The awakening device 65 may be the curtain opening / closing device 63, or the user 1 may be awakened by opening the curtain to brighten the room.

  The second wireless communication unit 24g wirelessly communicates with the relay device 40, and the external devices 61, 62, 63, and 64 are set so that the optimal temporary sleep depth setting unit 24b is set via the relay device 40. And awakening device 65 is controlled. In the bedroom of the user 1, an air conditioner 61, a lighting device 62, and a curtain opening / closing device 63 attached to a window are arranged as external devices. Moreover, the heater 64 is arrange | positioned at the backrest part of the temporary sleep chair 21, and a seat surface.

When the setting value storage unit 30c receives the setting values of the air conditioning device 61, the lighting device 62, and the heater 64 from the portable terminal 50 via the wireless communication unit 30b, the setting value storage unit 30c updates and stores the setting values.

(Operation)
Next, the operation will be described based on the flowchart 1 of FIG. 4 and the flowchart 2 of FIG. Flowchart 1 is an operation program of temporary sleeping chair ASSY20. The flowchart 2 is an operation program of the bed assembly 10. First, when the user 1 is seated on the temporary sleeping chair 21 (second bedding), the second biological information detection sensor 23 detects the weight of the user 1 and the program of the flowchart 1 is started. However, the present invention is not limited to this mode, and the user 1 may start the program by pressing the start button by himself / herself. The activation button may be provided in the second control unit 24.

  The flowchart 1 includes a second biological information detection step S101, a state detection step S102, a main sleep depth cycle acquisition step S103, an optimal temporary sleep depth setting step S104, a temporary sleep onset determination step S105, and a temporary sleep depth. Calculation step S106, optimal temporary sleep depth determination step S107, and awakening step S108.

  In step S101 (second biological information detection step), the second control unit 24 detects body motion vibration of the user 1 by the second biological information detection sensor 23, and acquires data. In step S102 (state detection step), the state detection unit 24a calculates the temperature, humidity, and brightness indicating the state of the bedroom where the bed 11 (first bedding) and the temporary sleep chair 21 (second bedding) are arranged. The data detected by the hygrometer and the illuminometer and detected by the second control unit 24 are acquired.

  In step S103, the second control unit 24 acquires “main sleep depth cycle” data in the main sleep immediately before (for example, the night of the previous day). The “present sleep depth cycle” data to be acquired is data that has already been acquired by the first control unit 15 that controls the flowchart 2 and is recorded by the depth cycle recording unit 15 c.

  Here, the flowchart 2 of FIG. 5 will be described. As described above, the flowchart 2 is an operation program of the bed assembly 10. The flowchart 2 includes a first biological information detection step S201, a main sleep / sleep determination step S202, a main sleep depth calculation step S203, and a depth cycle recording step S204.

  In step S201 (biological information detection step), the first control unit 15 causes the first biological information detection sensor 13 provided in the bed 11 (first bedding) to detect the body movement vibration of the user 1, and the body movement vibration data. To get. In step S202 (main sleep onset determination step), the main sleep onset determination unit 15a determines the main sleep onset in the user 1 sleep based on the first biological information signal 13a. In this sleep / sleep / sleep determination unit 15a, the first control unit 15 moves the control process to step S203 if it is determined to be sleep / sleep / sleep, and if it is determined to be awake, the first control unit 15 determines the determination result. Repeats the process of step S202 until this sleep falls asleep.

  In step S203 (main sleep depth calculation step), the main sleep depth calculation unit 15b sequentially calculates the main sleep depth after reaching the main sleep falling asleep as time elapses. In step S204 (depth cycle recording step), the main sleep depth cycle calculated by the main sleep depth calculation unit 15b is recorded by the depth cycle recording unit 15c. Thus, whenever the user 1 sleeps in the bed 11 and makes a main sleep, the program of the flowchart 1 is activated, and the “main sleep depth cycle” data is recorded by the depth cycle recording unit 15c. And this time, the state of this sleep depth cycle is very good, and it is assumed that the user 1 sleeps for a sufficient time at night, and therefore has no great fatigue or drowsiness during temporary sleep. The above is the program of the flowchart 2.

  Here, it returns to the flowchart 1. In the next step S104 (optimum temporary sleep depth setting step), the optimal temporary sleep depth setting unit 24b acquires the bedroom state data acquired in step S102 and the “main sleep depth cycle” data acquired in step S103 ( Based on the circles A and 2 in the flowcharts 1 and 2, the optimal temporary sleep depth and the external devices 61, 62, 63, and 64 are set for temporary sleep. As described above, the “present sleep depth cycle” data is in a good state as the present sleep. Thereby, the optimal temporary sleep depth setting unit 24b sets the optimal temporary sleep depth in the temporary sleep and the optimal temporary sleep depth setting step S104 in which each external device 61, 62, 63, 64 is set. Set a minimum state for Moreover, the setting which the optimal temporary sleep depth setting part 24b performs with respect to each external device 61, 62, 63, 64 is made to turn off only lighting, after closing a curtain. Specifically, the optimum nap depth is set so that the state of nap for 5 minutes becomes the optimum nap depth when it is determined that the user 1 on the nap chair 21 has fallen asleep. For each external device 61, 62, 63, 64, the second wireless communication unit 24 g wirelessly communicates with the relay device 40, and the optimal temporary sleep depth setting unit 24 b is set via the relay device 40. Information is transmitted so that the state is satisfied. Accordingly, the external device 62 (lighting device) is operated to be turned off, the external device 63 (curtain opening / closing device 63) is operated in the closing direction, and the room is darkened.

  In step S105 (a nap sleep determination step), the nap sleep determination unit 24c determines the user 1's nap sleep in the temporary sleep chair 21 (second bedding). At this time, the user 1's nap sleep is determined based on body motion vibration (biological information) detected by the second biological information detection unit 23. If the nap sleep / sleep determination unit 24c determines that a nap sleep has been reached, the process of the program moves to step S106. If the nap does not result in a sleep nap, step S105 is performed until the process of the program reaches a sleep nap. Repeated. However, at this time, if the user 1 does not readily fall asleep, the elapsed time that allows the state that does not lead to a nap fall is determined, and when the determined elapsed time is reached, the process returns to step S104, and each external device 61, 62 is reached. , 63, 64 may be set so as to be the optimal condition for the user 1 to fall asleep.

  In step S106 (temporary sleep depth calculation step), the temporary sleep depth calculation unit 24d measures the elapsed time from the sleep after falling asleep. Then, in step S107 (optimum temporary sleep depth determination step), the temporary sleep depth calculation unit 24d determines whether or not the elapsed time after falling asleep is the time set in step S104. Step S106 is repeatedly processed until the elapsed time after falling asleep is, for example, 5 minutes. Then, when the elapsed time becomes, for example, 5 minutes, step S106 moves to step S108.

  In step S108 (awakening step), the awakening device control unit 24f sends an activation signal to the awakening device 65, and the awakening device 65 activates the alarm to give the user 1 an auditory stimulus and awaken the user 1. As a result, the user 1 is awakened cleanly, and the originally reduced fatigue is completely recovered.

  In the above embodiment, in the description of the operation, the case where the acquired “present sleep depth cycle” data is data having no problem has been described. However, the “Sleep Depth Cycle” data, for example, has unstable sleep (see the two-dot chain line in FIG. 3) that is not shallow but deepened again at the position where the sleep depth should be shallow, or during sleep In this case, the content set in step S <b> 104 may be changed if the content of the sleep depth is too shallow and the content has been awakened (see the broken line in FIG. 3). In this case, in the flowchart 1, it is determined in step S103a whether the content of the “main sleep depth cycle” data is normal. If it is determined in step S103a that the determination result is “normal”, the process may move to step S104 as described above. However, if it is determined in step S103a that it is “not normal”, the process moves to step S104a, and the optimum temporary sleep depth setting unit 24b may perform a new setting corresponding to the “not normal” state.

  As a new setting according to the “not normal” state, for example, for the optimal temporary sleep depth, the duration of the temporary sleep after entering the temporary sleep is set to 15 minutes. The external devices 61, 62, 63, and 64 are set so that the user 1 has optimum conditions according to the “unnormal” state in order to promptly take a nap and to make a good nap. To do. Thereby, the fatigue of the user 1 is recovered well.

  Moreover, in the said embodiment, the time from the user 1 awakening state to a nap sleep and the quality of a nap was controlled by changing the setting of each external device 61, 62, 63, 64. However, as long as the user 1 can be awakened by the awakening device 65, the time until the nap sleep and the quality of the nap need not be controlled by the external devices 61, 62, 63, 64. This also provides a reasonable effect.

  Moreover, in the said embodiment, when calculating this sleep depth, it calculated | required using body motion vibration among biometric information. However, it is not limited to this aspect. You may obtain | require this sleep depth using other biometric information, such as a user's 1 brain wave, a heartbeat, and respiration. Moreover, although the determination of the sleep asleep and the nap sleep asleep was calculated | required using a body motion vibration, you may obtain | require here also by other biometric information (heartbeat, respiration, etc.).

  In the above embodiment, the second bedding is a chair. However, the present invention is not limited to this mode, and the second bedding may be a bed. Further, the second bedding may be the same bed as the first bedding.

  Moreover, in the said embodiment, although it was the aspect which applies each external device 61, 62, 63, 64, at least one should just be applied.

(Effect by embodiment)
According to the above-described embodiment, the temporary sleep control device 100 includes the bed 11 (first bedding) where the user 1 takes a regular sleep, the temporary sleep chair 21 (second bedding) where the user 1 takes a temporary sleep, and the bed 11. The first biological information detection sensor 13 (first biological information detection unit) that detects the first biological information vibration of the user 1 and outputs the first biological information signal 13a, and the temporary sleeping chair 21 are provided. Based on the second biological information detection sensor 23 (second biological information detection unit) that detects the second biological information vibration and outputs the second biological information signal, and the first biological information signal 13a, the main sleep of the user 1 Sleep sleep / sleep determination unit 15a for determining sleep sleep / sleep, sleep sleep calculation unit 15b for calculating the sleep depth of sleep based on the first biological information signal 13a after sleep sleep, and sleep Awakening time from sleep onset start time The depth cycle recording unit 15c that records the sleep depth cycle in which the sleep depth calculated by the sleep depth calculation unit 15b periodically increases and decreases, and the depth cycle recording unit 15c. The optimal temporary sleep depth setting unit 24b that sets the optimal temporary sleep depth of temporary sleep when taking a temporary sleep with the temporary sleep chair 21 based on the actual sleep depth cycle, and the second biological information signal 23a A temporary sleep onset determination unit 24c that determines a nap sleep onset in a nap, a temporary sleep depth calculation unit 24d that calculates a temporary sleep depth on the basis of the second biological information signal 23a after the nap The temporary sleeping depth calculated by the temporary sleeping depth calculating unit 24d reaches the set optimal temporary sleeping depth, and an optimal temporary sleeping depth determining unit 24e for determining whether or not the temporary sleeping sleep determining unit 24c is set. Depending on nap sleep Is a constant, provided the optimum temporary sleep depth determining unit 24e, when the user 1 is determined to have reached the optimum temporary sleep depth, and awakening device 65 to wake the user by applying a stimulus to the user 1, a.

  Thus, the optimal temporary sleep depth in temporary sleep is set based on the final sleep depth cycle of the final sleep performed before taking a temporary sleep. If it is determined that the sleep time is insufficient based on the main sleep depth cycle of the main sleep, the temporary sleep time is set to be longer, for example. If it is determined that the sleep time is sufficient based on the main sleep depth cycle of the main sleep, the temporary sleep time is set to be short. As a result, the night of the day after taking a nap does not prevent a person from sleeping because the nap time is too long. Also, there will be no temporary sleep time, and the person will not enter this sleep with severe fatigue. For this reason, in this sleep, sleep can be performed as usual, and fatigue is not carried over to the next day.

  Moreover, according to the said embodiment, the optimal temporary sleep depth determination part 24e performs determination by estimating that the optimal temporary sleep depth was reached when predetermined time passed after the temporary sleep falling asleep.

  From the experimental results so far, it has been found that in order to recover fatigue by temporary sleep, it is necessary to keep the sleep up to the second sleep depth of the four stages of sleep depth. Beyond this, it will affect nighttime sleep. And it is known that when a nap is performed, the nap depth reaches the second sleep depth in a relatively short time after nap sleep. Furthermore, it is also known that after reaching the second sleep depth, it does not shift to the third sleep depth within a predetermined time. Therefore, in the above aspect of the invention, the optimum temporary sleep depth is determined by the elapsed time after falling asleep. Thereby, it can determine easily and cost reduction can be achieved.

  Moreover, according to the said embodiment, in the temporary sleep control apparatus 100, the 1st and 2nd biometric information vibration of the user 1 is a user's 1 body motion vibration. Thereby, the biometric data can be easily acquired by an inexpensive load sensor or the like.

By changing, the user 1 includes external devices 61, 62, 63, and 64 that control at least one of the time until the nap falls to sleep and the quality of the nap of the user 1.

  Thereby, the user 1 can obtain comfortable room temperature, humidity, brightness, and the like, which is an environment for taking a good nap, by using the external devices 61, 62, 63, 64. The user 1 can easily fall asleep depending on the state of the environment, and a good quality sleep can be obtained after falling asleep. As a result, sleepiness can be relieved and fatigue can be recovered.

  Moreover, according to the said embodiment, an external apparatus is the temporary sleep chair 21 (2nd bedding) which heats up or cools the contact surface with the air conditioner 61, the illuminating device 62, the window curtain opening / closing device 63, and the user 1. It is at least one of the heater or the cooler (heat exchanger) arrange | positioned. Thus, a comfortable brightness state can be realized by operating the lighting device 62. Also, the brightness from the outside is adjusted by the operation of the window curtain opening / closing device 63, and a comfortable brightness state in the room can be realized. Furthermore, the limbs and the body are warmed or cooled by the heater or cooler of the temporary sleeping chair 21 to obtain a comfortable body temperature state. Thereby, it becomes easy to fall asleep, and a good quality sleep can be obtained after falling asleep.
