  Embodiments of the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is an explanatory diagram of a sleep environment control system 1 in the present embodiment. A bed 4 is installed on the floor 2 of the bedroom. The bed 4 has a frame 5, four legs 6 below the frame 5, a mattress 7 on the frame 5, and a headboard 8 on the side surface of the frame 5. A load meter 11 (load sensor) is installed between the four legs 6 and the floor surface 2. In the headboard 8, the user's sleep state and / or arousal state (sleepiness) is measured by measuring the amount of body movement and / or weight loss of the user (person on the bed) from the load of the load cell 11. ) Is determined. A control board (control unit) 12 is installed. On the wall surface 3 of the building, there is an air conditioner 13 that controls the temperature of the bedroom (room that accommodates the bed) in response to a set temperature signal that is determined by the control board 12 and is output from the control board 12 according to the user's sleep difficulty. is set up.

  The load meter 11 may use another load sensor such as a strain meter instead of the load meter 11. The room that accommodates the bed can be applied to other rooms such as a sickroom and a nursing room in addition to the bedroom.

  Next, the operation of this embodiment will be described.

  FIG. 2 is an operation flowchart of the sleep environment control system 1 in the present embodiment, and includes a start step S0 to a high temperature step S7 as follows.

(Start step S0)
The control board 11 detects that the AC 100V AC power source is connected to the sleep environment control system 1 and uses the load meter 11 to start measurement of the load applied to the mattress 7. In this step, the control board 11 reads the load applied to the load meter 11 in a state where the user such as the bed 4 or the mattress 7 is not on or allows the input separately. Then, when the user gets on the mattress 7, the user's weight can be read or separately input. Instead, a battery called an AA dry battery may be used as the AC 100V AC power source.

(Initial setting temperature input step S1)
When the user does not set the temperature of the air conditioner 13 at the time of entering or before and after the entry, the set temperature set when the user starts using the air conditioner 13 is set. When set, the set temperature is read into the control board 12 as an initial set temperature. The method of reading the initial set temperature into the control board 12 uses WiFi communication. It should be noted that instead of WiFi communication, other communication means such as a wireless LAN or the Internet can be substituted or combined with other communication means.

(Room temperature reading step S2)
The control unit measures the room temperature of the bedroom and reads it into the control board 12. It is also possible for the air conditioner to measure the room temperature in the bedroom and transmit it to the control board 12 using WiFi communication instead of the control unit.

(Air conditioner 13 control step S3)
The control unit controls the air conditioner 13 using WiFi communication so that the room temperature of the bedroom becomes the set temperature. The set temperature is set to the initial set temperature until the number of body movements exceeds a predetermined number before entering the bed and / or after entering the bed, or until the weight loss amount becomes a predetermined amount or less after entering the bed. The set temperature is set to a temperature 2 ° C. lower than the initial set temperature when the number of body movements exceeds a predetermined number after entering the floor. The set temperature is set to a temperature 2 ° C. higher than the initial set temperature when the weight loss amount becomes a predetermined amount or less after entering the floor. The predetermined number of body movements corresponds to a value of 0 in the calculation result of the sleep determination formula shown in FIG. The predetermined amount of weight loss corresponds to a value of 0 for weight loss.

(Load reading step S4)
The control unit reads the load applied to the load sensor installed on the leg 6 of the bed 4 every minute, converts the number of fluctuations of the load into the number of body movements of the user, and stores the number of body movements. The load reading interval can be changed.

(Body motion number calculation step S5)
The control unit converts the number of fluctuations of the load applied to the leg 6 of the bed 4 into the number of body movements, and stores the number of body movements.

(Number of body movements (sleep state) determination step S6)
The control board 12 converts the number of body movements into a sleep state from the sleep determination formula illustrated in FIG. That is, the control board 12 sleeps by subtracting a constant from the value obtained by multiplying the number of body movements per minute from 10 minutes before to 1 minute before each minute stored by the coefficient. Is calculated. If the calculation result exceeds 0, the control board 12 determines that the user is awake and feels sleepless. If the calculation result is 0 or less, the control board 12 determines that the user is in a sleep state and does not feel sleepiness.

(First temperature changing step S7)
If the calculation result of the sleep determination formula exceeds 0, the control board 12 determines that the user is awake and feels uncomfortable, and sets the set temperature from the initial set temperature to make it easier for the user to fall asleep. Also change the temperature to 2 ° C lower. Thereafter, the control board 12 returns the control to the room temperature reading step S2.

If the calculation result is 0 or less, the control board 12 determines that the user is in a sleep state and does not feel sleepiness, and maintains the current set temperature. In this case, the current set temperature is the set temperature set in the second temperature changing step S11 described later.

(Weight calculation step S8)
The control board 12 reads the load applied to the load sensor installed on the leg 6 of the bed 4 every minute, converts the load into the weight of the user, and stores the weight. The load reading interval can be changed.

(Weight loss calculation step S9)
The control board 12 calculates the weight loss amount of the user from the stored weight of the user.

(Weight loss (sleep state) determination step S10)
The control board 12 determines that the user is in a sleep state and does not feel uncomfortable when the weight loss amount of the user becomes 0 and the state of 0 continues for 5 minutes. The control board 12 returns the control to the room temperature reading step S2 until the weight loss amount of the user becomes 0 and the 0 state continues for 5 minutes.

(Second temperature changing step S11)
The control board 12 changes the set temperature to a temperature 2 ° C. higher than the initial set temperature in order to prevent the user's body from getting too cold when it is determined that the user is in a sleep state. Thereafter, the control board 12 returns the control to the room temperature reading step S2.

  It should be noted that instead of WiFi communication, other communication means such as a wireless LAN or the Internet can be substituted or combined with other communication means.

  FIG. 3 is a timing chart example of the number of body movements and weight of the user and the system operation and control temperature of the sleep environment control system 1 in the present embodiment. The control board 12 reads the initial setting value of the bedroom air conditioning temperature stored in the air conditioner 13 and starts or continues the air conditioning. When the load board 11 detects the body movement of the user, the control board 12 rapidly cools the user by lowering the bedroom air conditioning temperature of the air conditioner 2 by 2 ° C. from the initial setting value. Thereby, a user's body temperature falls gradually, a user's sleep is promoted, a user's perspiration reduces, and the sweat of a body surface evaporates. The load applied to the load meter 11 gradually decreases due to the evaporation of sweat, and the evaporation of sweat also stops after the user's sweating stops. The control board 12 raises the bedroom air conditioning temperature of the air conditioner 2 by 2 ° C. from the initial set value after the phenomenon that the load applied to the load meter 11 gradually decreases as the user stops evaporation of sweat. This operation is a control incorporated in the control board 12 because the user stops getting hot and sweating stops and the evaporation of sweat also stops, and if the user cools further, the health of the user is adversely affected.

  While the load meter 11 detects whether the user's weight has changed, that is, while the user is sleeping in the bed 4, the control board 12 initially sets the bedroom air conditioning temperature by detecting the amount of body movement through the load meter 11. The operation of lowering the temperature by 2 ° C. below the value and the operation of raising the bedroom air conditioning temperature by 2 ° C. above the initial set value by detecting the weight loss through the load meter 11 are repeated. When the load meter 11 no longer detects the weight of the user, that is, when the user wakes up, the control board 12 returns the bedroom air conditioning temperature to the initial setting value.

  Here, the initial setting value of the bedroom air conditioning temperature is described in a form stored in the air conditioner 13 in advance, but it may be changed by the user on the way. The user's weight reduction amount is set according to how the user normally sleeps, that is, where one or more of the user's face, hands, feet, and trunk are out of the comforter. Can be changed.

  FIG. 4 is an example of a sleep determination formula of the sleep environment control system 1 in the present embodiment. This sleep determination formula represents the “relationship between the number of body movements and the sleep state” based on the result obtained from the monitor evaluation. When the value Z calculated from the number of body movements of the monitor is greater than 0 (zero, a predetermined value of body movement), the monitor is awake, and when Z is 0 or less, it represents the sleep state. . The awake state includes a state in which the monitor's consciousness is on the bed 4 and a state in which the monitor does not remember going to the toilet even though he went to the toilet in a sleepy manner. From the monitoring results, the value of Z of the monitor described above matched the monitor's arousal and / or sleep state.

  FIG. 5 is an example of a sleep determination result inside the sleep environment control system 1 in this embodiment, (a) is an example of a sleep determination result, and (b) is an example of a result of a weight fluctuation amount. 4 is calculated in light of the sleep determination formula of FIG. 4, and the monitor person awakens before and after the time when the sleep determination value Z exceeds 0 in FIG. When the temperature was lowered by 2 ° C. from the initial set value, it was possible to promote the sleep of the monitor. Therefore, also in the sleep environment control system 1 in this embodiment, the operation of lowering the bedroom air conditioning temperature by 2 ° C. from the initial set value is performed based on the sleep determination formula of FIG. 4 and the setting change reference of FIG. Yes.

  In FIG. 5 (b), even when the weight fluctuation amount (change in the user's body movement) falls below the “maximum value of the differential weight fluctuation for five minutes from the time of bed entry” for five consecutive minutes, the bedroom air conditioning temperature is initially set. The operation is performed by 2 ° C. higher than the set value. In this movement, the fact that the user's body movement is smaller than the body movement for 5 minutes after entering the floor is judged to have eliminated the user's difficulty in sleeping. This is to prevent the health of the user from being adversely affected. This operation is performed as a backup control of the method in FIG. 3 which prevents the user from getting hot, stops sweating and stops sweat evaporation and prevents the user's health from being adversely affected by further rapid cooling. It can also be incorporated in the environmental control system 1. That is, even if the load reduction time is too long by the method shown in FIG. 3 and the user's body is cooled too much, the user's body is cooled too much by the method shown in FIG. Is reduced. However, in the monitor evaluation, the results shown in FIG. 3 and the method shown in FIG. 5 showed almost the same result, so this is a control method provided in case.
