  The awakening state determination unit 3 compares the user's biological information acquired by the biological information acquisition unit 2 with information indicating the user state stored in the user state storage unit 4 to determine whether the user is in an awakening state. I do. The user state storage unit 4 stores the user's biological information and information indicating the user's arousal state or non-awake state in association with each other.

  The control condition determination unit 5 determines the control condition in the corresponding control mode based on the determination result of the need determination unit 1 and the determination result of the arousal state determination unit 3. The control modes are an awakening mode and a nap mode. When transitioning to the awakening mode, the control condition determining unit 5 refers to the biological information acquired by the biological information acquiring unit 2 and the control condition accumulating unit 6, selects the device 50 that gives the user a stimulus for awakening, The control condition of the selected device 50 is determined. On the other hand, when the mode transitions to the nap mode, the control condition determination unit 5 refers to the biological information acquired by the biological information acquisition unit 2 and the control condition storage unit 6, selects the device 50 for prompting the user to sleep, The control condition of the selected device 50 is determined. The control condition accumulation unit 6 accumulates the device 50 to be controlled and the control condition of each device 50 in association with each control mode. The control conditions of each device 50 may be classified and set based on the gender and preferences of the user.

Realized. The user state storage unit 4 and the control condition storage unit 6 constitute a memory 12. Further, a plurality of processors 11 and a plurality of memories 12 may be configured to cooperate to execute the above-described functions.

Next, the operation of the environment control apparatus 10 will be described with reference to FIGS.
FIG. 3 is a flowchart showing the operation of the environment control apparatus 10 according to the first embodiment.
In addition, the biometric information acquisition part 2 shall acquire a user's biometric information based on the information always input from the various sensors 40. FIG.

  When the needs determination unit 1 receives an input of the user's needs from the HEMS remote controller 20 or the wearable device 30 (step ST1), the needs determination unit 1 refers to the input needs and the user wishes to guide to the awake state. It is determined whether it is desired to guide to a nap state, or whether it is desired to guide to an awake state and a nap state (step ST2). When the user wishes to be in the awake state (step ST2; awake), the mode shifts to the awake mode. On the other hand, when the user does not wish to be guided to the awake state (step ST2; nap), the process shifts to the nap mode. Furthermore, when the user does not wish to be guided to an awake state or a nap state (step ST2; neutral), the process returns to step ST1.

  First, the operation when shifting to the awakening mode will be described. The awake state determination unit 3 acquires the user's biometric information from the biometric information acquisition unit 2 (step ST3). The awake state determination unit 3 compares the biological information acquired in step ST3 with the information stored in the user state storage unit 4, and determines whether or not the user is in an awake state (step ST4). If the user is awake (step ST4; YES), the process returns to step ST1.

  On the other hand, when the user is not in the awake state (step ST4; NO), the control condition determining unit 5 determines whether or not each device 50 is already controlled in the awake mode (step ST5). When each device 50 is already controlled in the awakening mode (step ST5; YES), the control condition determining unit 5 determines whether or not the number of times of increasing the stimulation level for awakening the user has reached the set number. (Step ST6). If the set number of times has been reached (step ST6; YES), the process proceeds to step ST13 described later. On the other hand, when the set number of times has not been reached (step ST6; NO), the control condition determination unit 5 refers to the information stored in the control condition storage unit 6 and further increases the stimulation level for awakening the user. Control conditions are determined (step ST7). On the other hand, when not operating until now in the awakening mode (step ST5; NO), the control condition determining unit 5 refers to the information accumulated in the control condition accumulating unit 6 to determine the control conditions for awakening the user. (Step ST8).

  The device control unit 7 controls each device 50 under the control conditions determined in step ST7 or step ST8 (step ST9). The control condition determination unit 5 determines whether or not the device control unit 7 has executed control for each device 50 for a preset time or a preset number of times (step ST10). If control for a preset time or number of times has not been executed (step ST10; NO), the process returns to step ST9. On the other hand, when control is performed for a preset time or a preset number of times (step ST10; YES), the process returns to step ST3.

  Next, the operation when the nap mode is entered will be described. The awake state determination unit 3 acquires the user's biometric information from the biometric information acquisition unit 2 (step ST11). The awake state determination unit 3 compares the biological information acquired in step ST11 with the information stored in the user state storage unit 4, and determines whether or not the user is sleepy (step ST12). If the user is not sleepy (step ST12; NO), the process returns to step ST1.

  On the other hand, when the user is sleepy (step ST12; YES), the control condition determining unit 5 refers to the information accumulated in the control condition accumulating unit 6 and determines a control condition for relaxing the user (step ST13). ). The device control unit 7 controls each device 50 under the control condition determined in step ST13 (step ST14). The control condition determination unit 5 determines whether or not the device control unit 7 has performed control for each device 50 for a preset time or a preset number of times (step ST15). When the control for the preset time or the preset number of times has not been executed (step ST15; NO), the process returns to step ST14. On the other hand, when control is performed for a preset time or a preset number of times (step ST15; YES), the process returns to step ST11.

Here, accumulation examples of the user state accumulation unit 4 and the control condition accumulation unit 6 will be described.
FIG. 4 is a diagram illustrating an example of the user state stored in the user state storage unit 4 of the environment control apparatus 10 according to the first embodiment.
FIG. 4 shows a case where the user state is associated with the biological information acquired from the body motion sensor 40c. It is assumed that the user is in the awake state when the user's body movement more than the set number of times is detected within a certain time. Further, it is assumed that the user is sleepy when the user's body movement is detected within a certain time but is less than the set number of times. In addition, it is assumed that the user is not awake when the user's body movement is not detected within a certain period of time. The awakening state determination unit 3 determines the state of the user from the biological information acquired by the biological information acquisition unit 2 and the control conditions stored in the control condition storage unit 6.

FIG. 5 is a diagram illustrating an example of control conditions stored in the control condition storage unit 6 of the environmental control apparatus 10 according to the first embodiment of the present invention. FIG. 5 shows an example of control conditions that the control condition determination unit 5 refers to in the awakening mode.
As the control condition, the temperature of the air to be blown is set in accordance with the sex of the user and the preference of the user. Control conditions for blowing cooler air than male users are set for male users. In addition, a control condition is set for a hot male user to blow cooler air by −1 ° C. at the head and the foot than a cold male user. Specifically, a hot male user is blown by a wind (Ht in FIG. 5) lowered from room temperature by 3 ° C. near the head, and a wind (Ft in FIG. 5) raised by 1 ° C. from the room temperature to the feet. Control conditions for blowing air are set. In addition to the user's gender and preferences, control conditions according to the user's age and physique may be set and accumulated. In addition, the control conditions shown in FIG. 5 are examples, and are not limited to the numerical values shown by the control conditions.

  The biometric information acquisition unit 2 determines the user's gender, preference, age or age, physique, and the like from the captured image of the camera 40f. The biological information acquisition unit 2 outputs the user information to the control condition determination unit 5. Specifically, the biological information acquisition unit 2 measures the user's height, surface area, body temperature, and the like from the captured image of the camera 40f, further acquires information about the user's clothing, and whether the user is a man or a woman, Judge whether it is hot or cold. Further, the needs determination unit 1 may accept input of user information including age, physique, and preferences from the user and output the user information to the control condition determination unit 5. The control condition determination unit 5 collates the input user information with the information shown in FIG. 5 stored in the control condition storage unit 6 and determines the control condition of each device 50.

  In the example of FIG. 5, the principle of cold head heat that cools the head and warms the foot is applied as the stimulation by the wind to wake the user. In general, it is known that when a wind cooler than room temperature is blown near the user's head and a wind warmer than room temperature is blown near the user's feet, sleepiness is suppressed. FIG. 6 is a diagram showing a comparison of drowsiness levels depending on the presence / absence of air blowing of the air conditioner. FIG. 6A is a diagram illustrating the transition of the sleepiness level of the user when there is no wind blowing the user. FIG. 6B shows the transition of the sleepiness level of the user when the wind cooler than the room temperature is blown to the head when the sleepiness of the user is detected. The horizontal axis of FIG. 6 represents time, and the vertical axis represents sleepiness level (NEDO evaluation representing sleepiness).

The sleepiness level indicated by the vertical axis in FIG. 6 is defined as follows by NEDO evaluation (see Reference 1).
Sleepiness level 1: Not sleepy at all (the movement of the line of sight is fast and frequent, blinking is a stable cycle of about 2 times every 2 seconds)
Sleepiness level 2: Slightly sleepy (lips are open, movement of eye movement is slow)
Sleepiness level 3: Sleepy (blinks occur slowly and frequently, there are mouth movements, sit back, and do hands on the face)
Drowsiness level 4: Very sleepy (There is a blink that seems to be conscious. There is unnecessary movement of the whole body such as shaking the head, vertical movement of the shoulder, yawning frequently and deep breathing. slow)
Sleepiness level 5: Very sleepy (closes eyelids, head tilts forward, head falls back)

  In FIG. 6A, the sleepiness level increases from “1” to “4” or “5” with the passage of time. On the other hand, in FIG. 6B, the stimulus X by the first blow is given when 7 minutes have passed, the stimulus Y by the second blow is given when 9 minutes and 30 seconds have passed, and the stimulus Z by the third blow is given when 15 minutes have passed. Is given. In FIG. 6B, the sleepiness level increases with the passage of time, but the sleepiness level is suppressed to “3” or less even when 16 minutes have passed. From this, it can be seen that the user's sleepiness level can be kept low by blowing wind cooler than room temperature to the head.

Next, a specific example of control according to the subjective evaluation using the VAS described above will be described along the flowchart shown in FIG. In the following, an example will be described in which the needs determination unit 1 determines that the user's mood is “neutral”, “want to relax”, or “want to concentrate” based on the input subjective evaluation value.
<When subjective evaluation is “input value“ 0 ”: neutral”>
In step ST2 of the flowchart of FIG. 3, the need determination unit 1 determines that the user does not want to be guided to the awake state and the nap state, and returns to the process of step ST1. As described above, when the subjective evaluation is neutral, the control condition determination unit 5 stands by without performing either the control for awakening or the control for nap.

<When subjective evaluation is “input value“ −1 ”: I want to relax”>
In step ST2 of the flowchart of FIG. 3, the need determination unit 1 determines that the user does not want to be guided to the awake state. In step ST11 and step ST12, the wakefulness determination unit 3 determines that the user is sleepy (step ST12; YES), determines that the user's need for wakefulness is low, and allows the user to take a nap immediately. Transition to control. In step ST13 to step ST15, the control condition determination unit 5 and the device control unit 7 shift to control of an environment where the user can take a nap, determine a control condition for relaxing the user, and control each device 50. An example of control conditions for relaxing the user is shown below.
Air conditioner: Set the air temperature slightly warmer than the room temperature. A slightly warm wind is blown around the user's foot, and not near the user's head.
Lighting equipment: Make it darker than normal lighting.
Sound equipment: White noise with waves that oscillate up and down irregularly like natural sounds such as waterfalls and small birds.

<When subjective evaluation is “input“ 1 ”: I want to concentrate”>
In step ST2 of the flowchart of FIG. 3, the need determination unit 1 determines that the user desires guidance to the awake state. If it is determined in step ST3 and step ST4 that the user is not in an awake state (step ST4; NO), the awake state determination unit 3 determines that the user has a high need for an awake state, and shifts to control of an environment that can be awakened. . On the other hand, if it is determined that the user is in an awake state (step ST4; YES), the control condition determination unit 5 determines that the user is awake and concentrated. In that case, the control condition determination unit 5 waits without performing control for giving a stimulus for awakening.

Below, the specific example of the process of transfer to step ST5 is shown.
In step ST5 and step ST6, the control condition determination unit 5 gives a stronger stimulus to awaken the user in step ST7 when the device 50 is already controlled in the awake mode and can further increase the stimulation level. Determine the conditions. An example of control conditions for applying a stronger stimulus to wake the user is shown below.
Air-conditioning equipment: The wind speed is increased from 0.7 m / s to 2.0 m / s.
Stimulation time: Increase from 5 seconds to 15 seconds.
As described above, the user can be awakened by changing the intensity of the stimulus given to the user for awakening. In addition, the time which gives the wind speed mentioned above or irritation | stimulation is an example, and is not limited to the said numerical value.

In addition, in step ST5 and step ST8, the control condition determination unit 5 determines a control condition that gives a stimulus for awakening the user when the device 50 is not controlled in the awakening mode. An example of control conditions for providing a stimulus for awakening the user is shown below.
Air conditioner: Air that is cooler than room temperature is blown near the user's head, and air that is warmer than room temperature is blown to the user's feet.
Lighting equipment: Brighter than normal lighting.
Audio equipment: No sound is played.

  In step ST9 and step ST10, the device control unit 7 controls the various devices 50 and executes control for a set time or a set number of times. Thereafter, the arousal state determination unit 3 determines again in step ST3 and step ST4 whether the user is in the awake state. When the user is not in an awake state and cannot further increase the stimulation level in step ST5 and step ST6, it is determined that the user's physical condition is not excellent, and the process proceeds to step ST13. That is, it shifts to a nap mode and makes a user rest.

  In addition, when it is determined that the user does not wake up even if a stimulus is applied for a predetermined time or a predetermined number of times and the physical condition of the user is not excellent, the user shifts to the nap mode and the family is informed via HMES that the physical condition of the user is not excellent It is good also as a structure which notifies to the set person. For example, in the block diagram of the environment control apparatus 10 illustrated in FIG. 1, a notification unit connected to the device control unit 7 is additionally provided. When the device control unit 7 gives a stimulus to the user for a set time or set number of times and then shifts to the nap mode, the notification unit notifies the set person.

  Here, in the determination process of step ST10 in the flowchart of FIG. 3, the time or number of times for the control condition determination unit 5 and the device control unit 7 to execute control for awakening the user is set. This is because the awakening effect immediately appears in the first few seconds or several times when the user starts to stimulate, but the awakening effect decreases as the time or number of times the stimulus is applied increases. For this reason, the conditions for the time or number of times of stimulation are determined in advance, such as the time A seconds for giving the stimulation or the number of times B for giving the stimulation. If it is determined that the user has not been awakened even after the stimulation of the set condition is applied, the stimulation level is increased or the user is napped.

FIG. 7 is a diagram showing the probability of the user being awakened by the ventilation of the air conditioner for each number of times of ventilation. The horizontal axis indicates the number of air blows, and the vertical axis indicates the user's arousal rate. FIG. 7 shows the results when the air conditioner is controlled in the awakening mode.
The user's arousal rate exceeds 50% until the number of times the stimulus is applied by blowing air is the fourth. On the other hand, when the number of times of stimulation by blowing is 5th or later, the user's awakening rate is decreased, and the user is not awakened by the 8th and 9th blowing. Based on the result, by setting the maximum number of times that the device control unit 7 gives stimulation to the user, for example, 5 times, the user can be promptly rested.

  As described above, according to the first embodiment, the need determination unit 1 that accepts the user's needs and the wakefulness determination that determines whether or not the user is wakeful based on the user's biological information acquired from various sensors. Based on the determination result of the unit 3 and the need determination unit 1 and the determination result of the wakefulness determination unit 3, the control condition determination unit 5 shifts to the corresponding control mode and determines the control condition in the shifted control mode; Since it comprised so that the apparatus control part 7 which controls the apparatus 50 with the control conditions which the control condition determination part 5 determined can be controlled for the awakening according to a user's needs and a user's state.

  Further, according to the first embodiment, when the needs determination unit 1 determines the user's desire to guide to the awake state, and the awake state determination unit 3 determines that the user is not in the awake state, the control condition determination unit 5 Is configured to determine the control conditions for awakening, so when the user wants to guide to the awakening state, the control for awakening, such as blowing wind cooler than room temperature to the user's head It can be performed. Thereby, it can suppress that a user feels uncomfortable control for awakening.

  In addition, according to the first embodiment, the device control unit 7 performs control for giving a stimulus for awakening to the user a set number of times or a set time. If the user does not wake up, the device control unit 7 shifts to the nap mode. Therefore, taking into account the physical condition of the user who cannot wake up, the user can be encouraged to take a nap. Thereby, after a user takes a nap, it can be controlled to wake up comfortably.

  Moreover, according to this Embodiment 1, since the control condition determination part 5 was comprised so that a control condition might be determined according to a user's sex and liking, for example in the ventilation control of an air-conditioning apparatus, on a user's head. It is possible to perform a control of blowing wind cooler than room temperature and blowing wind warmer than room temperature to the user's feet, and the user can be awakened without feeling uncomfortable.

In the first embodiment described above, the control condition determination unit 5 performs the air flow control of the air conditioner.
Although an example in which wind cooler than room temperature is blown to the user's head and wind warmer than room temperature is blown to the user's feet has been shown, the control conditions of the air conditioner are not limited to this. Any air conditioning control for awakening the user can be applied. Moreover, although Embodiment 1 mentioned above demonstrated centering on ventilation control of an air conditioner, control for awakening a user using various apparatuses 50 other than an air conditioner or relaxing a user was carried out. Assumed to be performed.

Embodiment 2. FIG.
In this Embodiment 2, the structure for waking up comfortably after a user will be in a nap state is shown.
FIG. 8 is a block diagram showing the configuration of the environmental control apparatus 10a according to the second embodiment of the present invention.
The environment control device 10a of the second embodiment is provided with a nap state determination unit 8 in addition to the environment control device 10 shown in FIG. In the following, the same or corresponding parts as those of the environmental control apparatus 10 according to the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and the description thereof is omitted or simplified. .

  When the device control unit 7 starts controlling the device 50 based on the control conditions for the user to relax, the nap state determination unit 8 uses the electrooculogram measurement value of the electrooculogram sensor 40b acquired by the biometric information acquisition unit 2. It is determined whether or not the user is in a non-REM sleep state and a nap state. Thereafter, it is determined whether or not the non-REM sleep state has shifted to the REM sleep state. If it is determined that the REM sleep state has been entered, it is determined that the user's sleep is shallow, and the control condition determination unit 5 is instructed to determine a control condition for awakening the user.

  The control condition determination unit 5 determines a control condition for awakening based on an instruction from the nap state determination unit 8. The device control unit 7 controls each device 50 based on the determined control condition. The awake state determination unit 3 determines whether or not the user is in an awake state based on the biometric information of the user after performing control for awakening.

FIG. 9 is a flowchart showing the operation of the environment control apparatus 10a according to the second embodiment of the present invention. In the following, the same steps as those of the environmental control apparatus 10 according to the first embodiment are denoted by the same reference numerals as those used in FIG. 3, and the description thereof is omitted or simplified.
When the device control unit 7 controls the device in step ST14, the nap state determination unit 8 acquires the measurement value of the electrooculogram of the electrooculogram sensor 40b from the biological information acquisition unit 2 (step ST21). The nap state determination unit 8 determines whether the user is in a nap state based on the electrooculogram measurement value of the electrooculogram sensor 40b acquired in step ST21 (step ST22). If the user is not in a nap state (step ST22; NO), the determination process in step ST22 is continued. On the other hand, when the user enters the nap state (step ST22; YES), the nap state determination unit 8 determines whether the user has shifted to the REM sleep state (step ST23). When the user is not in the REM sleep state (step ST23; NO), the determination process in step ST23 is continued. On the other hand, when it determines with the user having shifted to the REM sleep state (step ST23; YES), it progresses to the process of step ST8.
