(2-1-5-2) Prediction Unit The prediction unit 192 predicts the drowsiness cycle of the subject 90 from the pre-nap information D11. The period of drowsiness is information about a time period during which the subject 90 feels drowsy and a time period during which the subject 90 is less likely to feel drowsiness. The drowsiness cycle, for example, is related to the subject's 90 circadian rhythm. The circadian rhythm is information that, for example, a person generally has the highest core body temperature around 4:00 pm and the lowest core body temperature around 4:00 am. Humans tend to feel strongly drowsy during periods of low core body temperature. In addition, during the daytime, people generally tend to feel sleepy between 2:00 pm and 4:00 pm due to the influence of the circa-Semidian rhythm. The subject's 90 circadian rhythm is, for example, information about the subject's 90 average wake-up time and average bedtime. Also, the circadian rhythm of the subject 90 is, for example, information as to whether the subject 90 is a morning person or a night person. For example, in the daytime, it may be considered that the subject 90 who is a morning person feels sleepy earlier than a general person. When the wake-up time on the day of the nap and the bedtime corresponding to the wake-up time on the day of the nap deviate from the average wake-up time and the average bedtime of the subject 90, the time during which the subject 90 feels sleepy. The belt may also shift. In addition, if the wake-up time of the target person 90 on the day of the nap is earlier than the average wake-up time, or if the bedtime corresponding to the wake-up time of the target person 90 on the day of the nap is later than the average bedtime, If the sleep time corresponding to the wake-up time on the day of the nap of the subject 90 is shorter than the average sleep time, the time period during which the subject 90 feels sleepy may be earlier. In the present embodiment, the prediction unit 192 uses, as the pre-nap information D11, the subject person 90's wake-up time on the day of the nap, bedtime corresponding to the wake-up time on the day of the nap, sleep duration corresponding to the wake-up time on the day of the nap, average The drowsiness cycle of the subject 90 is predicted from the typical wake-up time, average bedtime, average sleep time, daily sleep state evaluation value, subjective evaluation of drowsiness before a nap, sex, and age.

The administrator of the environment control content determination device 1, for example, uses data that associates the pre-nap information D11 of various people with the drowsiness cycle, and creates a deep learning model that predicts the drowsiness cycle from the pre-nap information D11. keep building. The prediction unit 192 predicts the drowsiness cycle by inputting the pre-nap information D11 into the deep learning model.

(2-1-5-3) Determining Unit The determining unit 193 determines the degree of arousal of the subject 90 in the scheduled nap time period D12 based on the temporal relationship between the scheduled nap time period D12 and the drowsiness cycle. , determines the contents of environment control for the target space SP where the target person 90 takes a nap.

Specifically, the determining unit 193 identifies a first time period in which sleepiness is felt and a short period of sleep is likely to occur, and a second time period in which sleepiness is less likely to occur and a short period of sleep is difficult to obtain, based on the drowsiness cycle. . The first time period is, for example, the afternoon or a time period in which the core body temperature tends to decrease. The second time period is, for example, the morning or a time period in which the core body temperature tends to rise. Then, the determination unit 193 determines a control pattern depending on whether the scheduled nap time period D12 corresponds to the first time period or the second time period. At this time, for example, if the sleep time corresponding to the wake-up time on the day of the nap is shorter than the average sleep time, or if the wake-up time on the day of the nap is earlier than the average wake-up time, or the wake-up time on the day of the nap If the bedtime is later than the average bedtime, it may be considered that the planned nap time slot D12 falls under the second time slot but falls under the first time slot.

Note that if the subject 90 has taken alcohol or caffeine such as coffee before taking a nap, the subject 90 is more likely to wake up due to alcohol or caffeine. The degree of arousal of the subject 90 may be determined in consideration of the time and amount of ingestion of . In addition, if the difference between the median time of bedtime on weekdays and the median time of bedtime on weekends, the so-called “social jet lag,” is, for example, one hour or more, sleepiness generally tends to occur. Taking this into consideration, the determination unit 193 may determine the degree of arousal of the subject 90 . In addition, when the subject 90 is a woman, the basal body temperature changes due to the influence of female hormones due to the menstrual cycle. The degree of arousal of the subject 90 may be determined. On the other hand, after ovulation, on the contrary, the basal body temperature rises, and considering that it is difficult to feel drowsiness, the determination unit 193 may determine the degree of arousal of the subject 90 .

The determination unit 193 determines the content of environment control by selecting from among a plurality of control patterns. The control pattern is expressed by the form in which the values of the control parameters relating to the environment of the target space SP change. In other words, the contents of environmental control are composed of control patterns and control parameters. The control parameters are at least the air volume, wind direction, wind speed, operation mode of the air conditioner 2 installed in the target space SP, indoor temperature, indoor humidity, illuminance, sound, scent, and inclination of the bedding in the target space SP. including one. For example, when the control parameter is the indoor temperature of the target space SP, the control pattern means when to raise the indoor temperature, when to make it constant, or when to lower it. It does not mean (how much to raise or lower the room temperature). In this embodiment, the determination unit 193 determines the details of environmental control by selecting from the first control pattern and the second control pattern. However, it is not limited to this, and the determination unit 193 may determine the content of environmental control by selecting from three or more control patterns. Further, in this embodiment, the indoor temperature of the target space SP is used as the control parameter.

FIG. 3 is a diagram showing the first control pattern. FIG. 4 is a diagram showing the second control pattern. 3 and 4 show how the room temperature of the target space SP changes from the scheduled nap start time to the scheduled nap end time (in other words, in the scheduled nap time zone D12).

When the scheduled nap time period D12 corresponds to the first time period, the determination unit 193 determines that the subject 90 is likely to fall into deep sleep, and selects the first control pattern. As shown in FIG. 3, the first control pattern raises the indoor temperature of the subject 90 before falling asleep, lowers and maintains the indoor temperature after detection of falling asleep, and maintains the indoor temperature at a predetermined time before the scheduled nap end time (hereinafter referred to as before waking up). This is a control that raises the room temperature during the period of time. The predetermined time is, for example, 5 minutes. If the scheduled nap time period D12 corresponds to the first time period, and the indoor temperature during sleep is maintained in the time period before waking up, the subject 90 will fall asleep too deeply. Select the first control pattern that raises the room temperature. The environment control content determination device 1 acquires the timing of falling asleep detection from, for example, a sleep monitor attached to bedding, and notifies the air conditioner 2 of the timing.

When the scheduled nap time period D12 corresponds to the second time period, the determination unit 193 determines that the subject 90 is in a state where it is difficult to fall asleep, and selects the second control pattern. As shown in FIG. 4, the second control pattern is a control for raising the room temperature before falling asleep of the subject 90, and lowering and maintaining the room temperature after the falling asleep is detected. When the scheduled nap time period D12 corresponds to the second time period, if the room temperature is raised in the time period before waking up, there is a high possibility that the subject 90 will wake up in the middle without getting enough sleep. , the determining unit 193 selects the second control pattern that maintains the room temperature during sleep in the time period before waking up.

The shape in which the value of the room temperature (control parameter) changes in the first control pattern and the second control pattern is determined for each subject 90 . Regarding the subject 90 who uses the environment control content determination device 1 for the first time, the form in which the indoor temperature value changes in the first control pattern and the second control pattern is similar to the subject 90 and the pre-nap information D11. It may be determined in a form in which the value of the indoor temperature of the person different from 90 changes, or in a form in which the value of the indoor temperature of the person in the past determined that the updating unit 194 has taken a sufficient nap. may Here, when the pre-nap information D11 is similar, for example, at least one of the sleep-related information, meal-related information, sex, age, generation, and thermal sensation of the subject 90 in the pre-nap information D11 is It means that they are the same. For example, the subject 90 and a person who has the same thermal sensation of sensitivity to heat or sensitivity to cold is considered similar to the subject 90 . Also, for example, a person whose average wake-up time or average bedtime is roughly the same as the target person 90 is considered similar to the target person 90 . In addition, regarding the subject 90 who uses the environment control content determination device 1 for the first time, the shape in which the indoor temperature value changes in the first control pattern and the second control pattern is the predetermined general-purpose indoor temperature value may be determined in a form in which

Regarding the subject 90 who uses the environment control content determination device 1 for the second time and thereafter, the shape in which the indoor temperature value changes in the first control pattern and the second control pattern is the shape in which the previous indoor temperature value changes. Alternatively, the value of the indoor temperature updated by the updating unit 194 last time changes.

(2-1-5-4) Update Unit The update unit 194 updates the target person 90 to take a sufficient nap based on the pre-nap information D11, the during-nap information D2, or the post-nap information D3 after the target person 90 has finished taking a nap. If it is determined that the target person 90 could not obtain the desired value, or that the subject 90 felt an unpleasant thermal sensation during a nap, the control parameter value transition form in the selected control pattern is updated. For example, when the control parameter is the indoor temperature of the target space SP, the updating unit 194 updates the transition width of the indoor temperature (how much the indoor temperature is increased or decreased) in the selected control pattern.

Specifically, if the nap duration is less than the threshold, if the duration of the predetermined sleep stage is less than the threshold, the update unit 194 updates the heart rate, breathing rate, pulse, or LF/HF during sleep in the nap information D2. If the standard deviation of is greater than the threshold, or if the subjective evaluation for drowsiness after the nap (post-nap information D3) is not better than the subjective evaluation for drowsiness before the nap (pre-nap information D11), enough It is determined that a nap was not taken. The nap time is, for example, the sum of the REM sleep time and non-REM sleep time in the during-nap information D2. The nap time threshold is, for example, a time corresponding to 70% of the scheduled nap time. The predetermined sleep stage time is, for example, the second stage non-REM sleep time. The predetermined sleep stage time threshold is, for example, a time corresponding to 50% of the nap time. For example, in the heartbeat of the subject 90 in the nap information D2, the update unit 194 may determine that the nap was not sufficient when the time during which a stable heartbeat was maintained during the nap is less than a threshold. .

In the first control pattern, if the update unit 194 determines that the subject 90 could not take a sufficient nap or that the subject 90 felt an uncomfortable thermal sensation during the nap, for example, the first control Reduce the gradient of room temperature in the time period before waking up in the pattern. In the second control pattern, if the updating unit 194 determines that the subject 90 did not take a sufficient nap, or that the subject 90 felt an unpleasant thermal sensation during the nap, for example, the second control Adjust the room temperature during sleep in the pattern to an appropriate temperature. In addition, for example, in the first control pattern and the second control pattern, the subject 90 evaluates that the subject 90 was hot during the nap in subjective evaluation of the thermal sensation during the nap. When it is determined that an unpleasant thermal sensation is felt during the nap, the indoor temperature is lowered during the nap. Further, for example, in the first control pattern and the second control pattern, the subject 90 evaluates that the subject 90 was cold during the nap in the subjective evaluation of the thermal sensation during the nap. When it is determined that an unpleasant thermal sensation is felt during the nap, the room temperature is raised during the nap.
