User authentication is performed by this user information, and the building 100 used by the user is specified.

The control unit 35 connects to the device 200 that adjusts the sleeping environment via the network NW2, and controls the device 200 set as the operating device. The control unit 35 controls the operation device so that the sleep environment is set according to the biological information in the time zone from the sleep onset time set in the storage unit 34 to the wake-up time.

For example, the control unit 35 may control the device so that the sleep environment acquired by the sleep environment acquisition unit 32 becomes a sleep environment according to the biological information in the time zone from the sleep onset time to the wake-up time. As an example, the control unit 35 controls the air conditioner 200-1 according to the body temperature, which is the biological information acquired by the biological information acquisition unit 31, in the time zone from the time of falling asleep to the time of waking up, in the control space 110. Adjust the temperature. The information processing device 30 can provide a more comfortable sleeping environment to the user.

The control unit 35 connects to the lighting device 200-2 in the control space 110 via the network NW2. The control unit 35 controls the lighting device 200-2 so that the illuminance in the control space 110 decreases as the current time approaches the time set as the sleep onset time. The information processing device 30 can realize a comfortable sleep onset for the user.

The control unit 35 is connected to the switchgear 200-3 that opens and closes the switchgear in the control space 110 via the network NW2. When the current time reaches the time set as the wake-up time, the control unit 35 controls the switchgear 200-3 to operate the switchgear in the open state. The information processing device 30 can realize a user's awakening.

The information processing device 30 may be configured by one or more servers. For example, the information processing apparatus 30 may include an application server, a database server, and a client server. For example, the application server has the functions of the biological information acquisition unit 31, the sleep environment acquisition unit 32, the setting unit 33, and the control unit 35. For example, the database server stores device information, weather information, and the like obtained from the device 200. The client server stores user information of the user. For example, an application server sends and receives data to and from each of a database server and a client server using an API (Application Programming Interface).

For example, the information processing apparatus 30 collates the authentication information of the user information stored in the storage unit 34 with the authentication information obtained from the communication terminal 20, and if the collation is successful, the access from the communication terminal 20 is performed. Allow. Then, the information processing apparatus 30 determines, for example, the building 100 used by the user based on the user information stored in the storage unit 34.

The flow of the operation of the process for controlling the sleep environment in the information processing apparatus 30 will be described with reference to FIG. In the example shown in FIG. 2, each device 200 of the building 100-m is an operating device.

The control unit 35 controls the lighting device 200-2 in the control space 110 from a time before a predetermined time from the sleep onset time, and gradually reduces the illuminance in the control space 110 (step S101). For example, the control unit 35 gradually or continuously lowers the illuminance so that the illuminance in the control space 110 becomes a set value at the time of falling asleep.

The control unit 35 determines whether or not the current time is the sleep onset time (step S102). When the current time reaches the sleep onset time, the control unit 35 shifts to the sleep mode. After shifting to the sleep mode, the biological information acquisition unit 31 starts acquiring the biological information of the user (human body) in the control space 110 (step S103). Further, when the mode shifts to the sleep mode, the sleep environment acquisition unit 32 starts acquiring the environment data in the control space 110 (step S103).

The control unit 35 grasps the sleeping environment in the control space 110 by the environment data. The control unit 35 controls the air conditioner 200-1 according to the body temperature information obtained at regular intervals (step S104). For example, the temperature drops at night or at dawn due to radiative cooling. Therefore, the body temperature of the user drops, and the user may get up in the cold. When the control unit 35 detects a decrease in the body temperature of the user, the control unit 35 raises the air temperature in the control space 110 according to the decrease. As a result, the control unit 35 can provide a comfortable sleeping environment.

To sleep, if the body temperature is high, it may not be possible to cool the body well and fall asleep. The control of step S104 may be performed after a predetermined time has elapsed from the user falling asleep. The control unit 35 may lower the air temperature in the control space 110 according to the body temperature of the user. For example, the control unit 35 may control the air temperature in the control space 110 so that the user's body temperature falls within a preset range.

The control unit 35 determines whether or not the current time is the wake-up time (step S105). If the control unit 35 determines that the current time is not the wake-up time, the control unit 35 returns to step S104. On the other hand, when the control unit 35 determines that the current time is the wake-up time, the control unit 35 cancels the sleep mode and raises the illuminance in the control space 110 (step S106). For example, when the control unit 35 determines that the current time is the wake-up time, the control unit 35 controls the lighting device 200-2 to increase the illuminance. For example, when the control unit 35 determines that the current time is the wake-up time, the control unit 35 may control the switchgear 200-3 to control the switchgear to the open state. When the opening / closing body is controlled to be in the open state, sunlight is incident on the control space 110, and the illuminance in the control space 110 is increased. In step S106, the control unit 35 may control at least one of the lighting device 200-2 and the switchgear 200-3. The information processing device 30 can provide a user's awakening.

The sleep environment control system 1 of the first embodiment includes a biological information acquisition unit 31 and a control unit 35. The biological information acquisition unit 31 acquires the biological information of the human body in the control space 110 via the network NW2. The control unit 35 controls the device 200 by connecting to the device 200 that adjusts the sleeping environment via the network NW2. The control unit 35 controls the device 200 so that the sleep environment corresponds to the biological information acquired by the biological information acquisition unit 31 during the time period from falling asleep to waking up.

With such a configuration, the sleep environment control system 1 can provide a sleep environment according to the sleeping user.

The control unit 35 may adjust the sleeping environment such as temperature and humidity in the control space by controlling the air conditioner 200-1 in the control space 110 according to the biological information. With such a configuration, the sleep environment control system 1 can provide a sleep environment according to the temperature and humidity of the sleeping user.

The control unit 35 may control the lighting device 200-2 so that the illuminance in the control space 110 decreases as the current time approaches the time set as the sleep onset time. The control unit 35 can provide a comfortable sleep-onset environment and a sleep environment by adjusting the temperature and the illuminance in the control space 110.

When the current time becomes the wake-up time, the control unit 35 may increase the illuminance in the control space 110 to a predetermined illuminance. With such a configuration, the control unit 35 can provide a comfortable wake-up environment.

The control unit 35 may determine whether or not the person has fallen asleep based on the biological information. In this case, the control unit 35 sets the time when it is determined to fall asleep based on the biological information as the sleep onset time. The user may operate the communication terminal 20 when falling asleep. In this case, the control unit 35 sets the time when the communication terminal 20 is operated as the sleep onset time.
