    By the way, when the user's life rhythm changes, such as weekdays and holidays, late and early work, etc., sleep time and wake-up time change. Therefore, in order to accurately perform temperature control for prompting the user to sleep, it is necessary to change the time change of the set temperature corresponding to the change of the life rhythm.

    However, the air conditioning control system of Patent Document 1 has only one operation mode for encouraging sleep of a sleeper. Therefore, every time the life rhythm changes, the user has to change the setting content of the operation mode to change the time change of the set temperature, which is troublesome for the user.

    This invention is made | formed in view of this point, and it aims at reducing the user's setting burden for changing the time change of preset temperature corresponding to the change of a life rhythm.

    1st invention presupposes the air-conditioning control system which controls the preset temperature T of the air conditioner (10) in a bedroom (5) during bedtime. And this air-conditioning control system has a storage part (36) which memorize | stores the several operation mode from which the time change of setting temperature T differs, and the operation mode of each day is selected by the user among the operation modes of a memory | storage part (36). The input part (37) selected and input, and the execution part (47) which performs the said operation mode input into the input part (37) are provided.

    In the first aspect of the invention, a plurality of operation modes having different time changes of the set temperature T are stored in the storage unit (36), and the operation mode of each day is selected by the user from the operation modes of the storage unit (36). It is selected and input to the input unit (37). Therefore, the user can change the time change of the set temperature T only by selecting a different operation mode. Further, the user can select a plurality of days of operation mode collectively.

    According to a second aspect, in the first aspect, the plurality of operation modes are set such that different scheduled wake-up times ta are set, and the set temperature T rises before each scheduled wake-up time ta.

    In the second aspect of the invention, different scheduled wake-up times ta are set for a plurality of operation modes. Therefore, when the user wants to change the scheduled wake-up time ta, a different operation mode is selected by the user and input to the input unit (37). Then, when the operation mode is executed in the execution unit (47), the set temperature T increases in accordance with the scheduled wake-up time ta after the change.

    In a third aspect based on the first aspect, the plurality of operation modes include a first operation mode in which the scheduled wake-up time ta is set and the set temperature T rises before the planned wake-up time ta, and the planned wake-up time ta And a second operation mode in which is not set.

    In the third aspect, the first operation mode in which the scheduled wake-up time ta is set and the second operation mode in which the scheduled wake-up time ta is not set are set as the operation modes. When the first operation mode is executed in the execution unit (47), the set temperature T before the scheduled wake-up time ta increases. On the other hand, when the second operation mode is executed, the set temperature T does not increase unlike the first operation mode. Accordingly, the first operation mode is set when the user wants to increase the set temperature T before getting up, and the second operation mode is set when the user does not want to increase the set temperature T.

    According to a fourth aspect of the present invention, in the first aspect, the input unit (37) selects a weekday operation mode and a holiday operation mode from the operation modes of the storage unit (36) by the user. Is selected and input.

    In the fourth aspect of the invention, when the user selects the operation mode for weekdays and the operation mode for holidays, the operation mode for weekdays is input all at once on weekdays, and the operation mode for holidays is collectively input on holidays. Entered. Therefore, the user need only select the weekday operation mode and the holiday operation mode in the input unit (37), and does not need to select the operation mode for each day individually.

    According to the present invention, a plurality of operation modes having different time changes of the set temperature T are stored in the storage unit (36), and the user selects the operation mode for each day from the operation modes of the storage unit (36). And it was made possible to input to the input part (37). Thereby, the user can change the time change of the set temperature T only by selecting a different operation mode according to daily life rhythm. Therefore, the user's setting work for changing the time change of the set temperature T can be made easier than before. In addition, the user can select and input the operation modes for a plurality of days at a time using the input unit (37). Therefore, for example, if the user inputs the operation mode for one month at a time, it is not necessary to change the time change of the set temperature T every time the life rhythm is changed as in the prior art. In this way, the user's setting burden can be reduced.

    Further, according to the second invention, different scheduled wake-up times ta are set for a plurality of operation modes. Therefore, even if the user's scheduled wake-up time ta changes, if another operation mode is set and executed, the set temperature T can be raised in accordance with the changed wake-up scheduled time ta. Therefore, as the set temperature T rises, the body temperature of the user who goes to sleep is promoted, and the user's awakening can be improved.

    According to the third aspect of the invention, the first operation mode in which the scheduled wake-up time ta is set and the second operation mode in which the scheduled wake-up time ta is not set are set as the operation modes. When the first operation mode is executed, the set temperature T rises before the scheduled wake-up time ta, so that the body temperature rise before wake-up is promoted, and the user can obtain a pleasant awakening. On the other hand, when the second operation mode is executed, the set temperature T does not increase, so that the state of prompting sleep is continued and comfortable sleep can be obtained. Therefore, the user can select the first operation mode when he / she wants to wake up comfortably at the wake-up time, and can select the second operation mode when he / she wants to sleep comfortably without worrying about the wake-up time.

    According to the fourth aspect of the invention, the operation mode for weekdays and the operation mode for holidays are selected in batch by the user and input to the input unit (37). Thereby, the user can set the operation mode of each day only by selecting the operation mode of a weekday and the operation mode of a holiday. Therefore, the user does not have to individually select the operation mode for each day, and the user's setting burden can be further reduced.

It is comprised so that it may output to a part (43).

    The heart rate detection unit (42) is configured to derive a heart rate from the body motion signal output from the signal processing unit (41). Specifically, the heart rate detection unit (42) extracts a signal in the frequency band of the heart rate as an actual measurement value from the body motion signal using a heart rate extraction filter, and calculates an average value of heart rate (heart rate per minute from the actual measurement value). Number average value). Then, a value obtained by removing a noise signal due to rough movement such as turning over from the average heart rate value is derived as a heart rate.

    The determination unit (43) is configured to perform a bedtime determination and a sleep determination of the sleeping person based on the body motion signal output from the signal processing unit (41). The determination unit (43) includes an in-bed determination unit (44) and a sleep onset determination unit (45).

    The occupancy determination unit (44) determines whether the sleeping person is in the bedding (6) or is out of the bedding (6). The determination by the presence determination unit (44) is performed by comparing the body motion signal output from the signal processing unit (41) with a predetermined determination threshold value (the presence determination threshold value). Specifically, in the presence determination unit (44), when the body motion signal is below the presence determination threshold, it is considered that no body motion has occurred from the sleeper. Is done. On the other hand, in the presence determination unit (44), when the body motion signal continues for a predetermined time or longer and exceeds the presence determination threshold, it is considered that the body motion has occurred from the sleeping person. The floor is determined.

    The sleep detection unit (45) determines whether or not the sleeper has fallen asleep based on the body motion signal after the bed determination unit (44) determines that the user is “in bed”. The determination by the sleep determination unit (45) is performed by comparing the body motion signal output from the signal processing unit (41) with a predetermined determination threshold (sleep determination threshold). Specifically, when the body motion signal continues for a predetermined time or longer and falls below the sleep determination threshold for the first time in the sleep determination unit (45), it is considered that there is not much body motion from the bedridden in bed. In this case, it is determined as “sleeping”. Further, in the sleep determination unit (45), after the determination of “sleeping”, if the body motion signal continues for a predetermined time or longer and exceeds the sleep determination threshold, it is considered that the body motion is generated from the sleeper. Therefore, it is determined as “awakening”.

    The periodic component extraction unit (46) uses a zero-phase filter to periodically detect signals periodically detected from the heart rate derived by the heart rate detection unit (42) (hereinafter referred to as ultradian rhythm). Is called a period).

    The air conditioning control unit (47) performs an operation mode based on a command signal output from the input unit (37), and derives a set temperature T to be transmitted to the air conditioner (10). The execution part which concerns on is comprised. The set temperature T is derived by superimposing the increase / decrease value T2 on the reference value T1. The air conditioning control unit (47) includes a basic control unit (48), a rhythm operation control unit (49), and a calculation unit (50).

    The basic control unit (48) derives the reference value T1. For example, in the weekday mode and the holiday mode, as shown in FIG. 4A, the reference value T1 decreases until it reaches the lower limit temperature Tb after it is determined to be “sleeping”, and then decreases to the lower limit temperature Tb. Maintains the lower limit temperature Tb, rises a predetermined time before the scheduled wake-up time ta, and reaches the target temperature Ta at the planned wake-up time ta. Thus, when the weekday mode and the holiday mode are executed, the reference value T1 is V-shaped controlled.

    The rhythm operation control unit (49) derives an increase / decrease value T2 (base temperature Tbase + Δt) according to the ultradian rhythm cycle (FIG. 4B). Specifically, the rhythm operation control unit (49) derives the differential value of the ultradian rhythm cycle extracted by the periodic component extraction unit (46), and increases the increase / decrease value T2 when the differential value is maximized. On the other hand, when the differential value becomes minimum, the increase / decrease value T2 is decreased. In the present embodiment, as shown in FIG. 4 (c), the rhythm operation control unit (49) sets the increase / decrease value T2 as Δt = 1 ° C. when the gradient of the forward change in the ultradian rhythm cycle is maximum. Increase by 1 ° C. That is, the increase / decrease value T2 is higher by 1 ° C. than the base temperature Tbase. On the other hand, when the differential value of the ultradian rhythm period becomes minimum, the rhythm operation control unit (49) sets Δt = 0 ° C. and sets the increase / decrease value T2 to the base temperature Tbase itself. That is, it becomes lower by 1 ° C. than the increase / decrease value T2 when the differential value becomes maximum. Here, the base temperature Tbase is set to the lower limit temperature Tb, for example.

    The calculation unit (50) derives a set temperature T to be transmitted to the air conditioner (10). As shown in FIG. 4D, the set temperature T is derived by superimposing the increase / decrease value T2 of the rhythm operation control unit (49) on the reference value T1 of the basic control unit (48).

-Operation of air conditioners and air conditioning control systems-
First, before starting the operation of the air conditioner (10), the setting of the operation mode and the execution date of the operation mode are performed by the user's operation.

    The operation mode is set in the storage unit (36). In the present embodiment, a weekday mode and a holiday mode are set as the operation mode. When setting each operation mode, parameters such as the target temperature Ta and the scheduled wake-up time ta are input.

    The execution date of the operation mode is set by the input unit (37). The execution date of the operation mode is set by the user selecting and inputting the operation mode of each day from the operation modes of the storage unit (36). In the present embodiment, the weekday mode is set in batch for each weekday, and the holiday mode is set in batch for each holiday.

    Next, when the user selects “cooling operation” or “heating operation” before going to bed and starts the operation of the air conditioner (10), the control operation based on the flowchart of FIG. 5 is performed.

    In step ST1, a command signal is output from the input unit (37). The output command signal is input to the air conditioning control unit (47). In the air conditioning control unit (47), the operation mode is executed based on the input command signal.

    In step ST2, the body movement of the sleeping person on the bedding (6) is detected by the pressure-sensitive tube (20) and the pressure receiving part (33). The detected body motion signal is modulated into a predetermined frequency band by the signal processing unit (41), and is output to the heart rate detection unit (42) and the determination unit (43).

    Further, the heart rate detector (42) derives the heart rate from the body motion signal, and the period component extractor (46) extracts the ultradian rhythm period from the heart rate.

    In step ST3, the bed presence / absence determination is performed by the bed determination unit (44). If it is determined that the user is present, the process proceeds to step ST4.

    In step ST4, the sleep determination of the sleeper is performed by the sleep determination unit (45). If it is determined “sleeping”, the process proceeds to step ST5.

    In step ST5, if it is determined as “sleeping”, control of the reference value T1, the increase / decrease value T2, and the set temperature T is started in each part (48, 49, 50) of the air conditioning control part (47).

    In the basic control unit (48), the reference value T1 is V-shaped controlled, and the reference value T1 is increased or decreased as shown in FIG.

    In the rhythm operation control section (49), the increase / decrease value T2 is controlled to increase / decrease corresponding to the ultradian rhythm cycle. Specifically, a differential value of the ultradian rhythm period (see FIG. 4B) extracted by the periodic component extraction unit (46) is derived, and it is detected whether the differential value is a maximum or a minimum. The In the rhythm operation control unit (49), when the maximum of the differential value of the ultradian rhythm cycle is detected (Xt in FIG. 4B), Δt is set to 1 ° C. Thereby, as shown in FIG.4 (c), the increase / decrease value T2 of an air conditioner (10) is set to a value higher 1 degreeC than the base temperature Tbase. On the other hand, when the minimum of the differential value of the ultradian rhythm period is detected (Yt in FIG. 4B), Δt is set to 0 ° C. Thereby, the increase / decrease value T2 of the air conditioner (10) becomes the same as the base temperature Tbase. Therefore, the increase / decrease value T2 increases when the differential value of the ultradian rhythm period becomes maximum, and then decreases when the differential value becomes minimum, which is repeated for each period of the ultradian rhythm.

    In the calculation unit (50), the increase / decrease value T2 of the rhythm operation control unit (49) is superimposed on the reference value T1 of the basic control unit (48), and the set temperature T is derived as shown in FIG. The This set temperature T is output as a signal to the air conditioner (10). The air conditioning capability of the air conditioner (10) is controlled so that the temperature in the bedroom (5) approaches the set temperature T. As described above, when the temperature in the bedroom (5) is V-shaped and the ultradian rhythm is controlled, an increase in body temperature and a decrease in body temperature of the user who is sleeping are promoted. Therefore, a sleeping user can obtain deep sleep without imposing so much burden on the body.

    In step ST6, the air conditioning control unit (47) determines whether or not the scheduled wake-up time ta has been reached. When it is determined that the scheduled wake-up time ta is reached, the process proceeds to step ST7, and the operation of the air conditioner (10) is stopped.

    In the present embodiment, the storage unit (36) stores a weekday mode and a holiday mode as operation modes. In the input unit (37), the weekday mode is set on each weekday, and the holiday mode is set on each holiday. Therefore, during weekdays, a command signal for executing the weekday mode is output from the input unit (37) and the weekday mode is executed. When a holiday occurs, a command signal for executing the holiday mode is output from the input unit (37). The holiday mode is executed.

    In addition, when the weekday mode and the holiday mode are executed, the reference value T1 is V-shaped, and the set temperature T rises before the scheduled wake-up time ta. Therefore, a rise in body temperature before getting up is promoted, and the user can wake up without imposing much burden on the body.
