[Figure 3] FIG. 10 is a diagram illustrating an example of a schematic configuration of a sleeping environment control system according to a second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0008] A sleep environment control system according to this embodiment will be described with reference to the drawings.

[0009] First Embodiment The sleep environment control system 1 according to the first embodiment is a system capable of wirelessly remotely controlling multiple devices 200 in a controlled space 110 installed in a building 100 such as a house, hospital, or nursing home. This controlled space 110 is, for example, a bedroom.

[0010] The multiple devices 200 are devices that adjust the sleep environment within the controlled space 110. A user who uses the sleep environment control system 1 goes to sleep within the controlled space 110. The sleep environment is the environment within the controlled space 110 when the user goes to sleep. For example, the sleep environment includes the temperature within the controlled space 110. The sleep environment may also include the humidity and illuminance within the controlled space 110.

[0011] As an example of the first embodiment, an air conditioner 200-1, a lighting device 200-2, and an opening / closing device 200-3 are installed in the controlled space 110. The air conditioner 200-1 adjusts the temperature and humidity in the controlled space 100. The lighting device 200-2 adjusts the illuminance in the controlled space 100. The lighting device 200-2 is, for example, an LED (light emitting diode) light. The opening / closing device 200-3 opens and closes an opening / closing body provided in the controlled space 110 to let sunlight into the controlled space 110. The opening / closing device 200-3 opens and closes an opening / closing body provided in the controlled space 110 to let outside air into the controlled space 110. The opening / closing body may be a curtain, a blind, a window (including a skylight), or the like. When the air conditioner 200-1, the lighting device 200-2, and the opening / closing device 200-3 are not distinguished from one another, they will be referred to as "devices 200."

[0012] The environment measuring device 300 is installed in the controlled space 110. The environment measuring device 300 measures the sleep environment in the controlled space 110. For example, the environment measuring device 300 measures the temperature and humidity in the controlled space 110. The environment measuring device 300 may also measure the illuminance, amount of carbon dioxide, and amount of carbon monoxide in the controlled space 110. The environment measuring device 300 transmits the measured temperature, humidity, illuminance, amount of carbon dioxide, and amount of carbon monoxide (hereinafter referred to as "environmental data") to the sleep environment control system 1.

[0013] The biological information detection device 400 measures the biological information of a user. The biological information of the user includes at least the user's body temperature. The biological information of the user may also include information such as heart rate, respiratory rate, and non-REM sleep. The biological information detection device 400 may be equipped with multiple sensors to measure the biological information, or these sensors may be separate. The biological information detection device 400 may use a contact sensor in which a sensor element is in contact with the human body to measure the biological information, or a non-contact sensor in which a sensor element is not in contact with the human body to measure the biological information. For example, the biological information detection device 400 may be a wearable device that measures the biological information. The biological information detection device 400 may also measure body temperature using a thermal camera. The biological information detection device 400 transmits the measured biological information to the sleep environment control system 1.

[0014] An example of the configuration of the sleeping environment control system 1 according to the first embodiment will be described below. As shown in FIG.

[0015] The gateway 10 connects the information processing device 30 and one or more devices 200. For example, the gateway 10 communicates wirelessly with one or more devices 200. The gateway 10 of the first embodiment relays information between the information processing device 30 and each of the air conditioner 200-1, the lighting device 200-2, and the opening and closing device 200-3. For example, the gateway 10 is connected to the air conditioner 200-1, the lighting device 200-2, and the opening and closing device 200-3 via a first network NW1, and is connected to the information processing device 30 via a second network NW2.

[0016] The gateway 10 connects the information processing device 30 and the environment measuring device 300. The gateway 10 relays information exchange between the environment measuring device 300 and the information processing device 30. The gateway 10 connects the information processing device 30 and the biological information detecting device 400. The gateway 10 relays information exchange between the biological information detecting device 400 and the information processing device 30. For example, the gateway 10 is connected to the environment measuring device 300 and the biological information detecting device 400 via a first network NW1, and is connected to the information processing device 30 via a second network NW2.

[0017] The first network NW1 and the second network NW2 may be wireless communication transmission paths (e.g., wireless LANs) or a combination of wireless communication transmission paths and wired communication transmission paths. The first network NW1 and the second network NW2 may be a mobile communication network such as a mobile phone network, a wireless packet communication network, the Internet, a dedicated line, or a combination thereof. For example, the first network NW1 and the second network NW2 may use a low-power wide-area network (LPWAN), or may use short-range wireless communication standards such as ZigBee (registered trademark), Wi-Fi (registered trademark), or BLE.

[0018] In the first embodiment, the first network NW1 and the second network NW2 are different communication networks, for example. For example, the first network NW1 is Wi-Fi or BLE. For example, the second network NW2 is a wireless LAN.

[0019] The communication terminal 20 transmits and receives information to and from the information processing device 30 by wireless or wired communication. In the first embodiment, the communication terminal 20 wirelessly communicates with the information processing device 30 via a third network NW3. The third network NW3 may be a wireless communication transmission path (e.g., a wireless LAN) or a combination of a wireless communication transmission path and a wired communication transmission path. The third network NW3 may be a mobile communication network such as a mobile phone network, a wireless packet communication network, the Internet, a dedicated line, or a combination thereof. For example, the third network NW3 may use a low-power wide-area network (LPWAN), or may use a short-range wireless communication standard such as ZigBee, Wi-Fi, or BLE. The third network NW3 may be the same network as the second network NW2.

[0020] The communication terminal 20 is, for example, a portable information terminal that can be carried by a user. For example, the communication terminal 20 is any one of a mobile phone, a smartphone, a tablet terminal, and a laptop computer. The communication terminal 20 may also be a wearable terminal, etc. There is no particular limitation on whether the communication terminal 20 can be carried by a user. For example, the communication terminal 20 may be a computer. In the following explanation, a case where the communication terminal 20 is a portable information terminal will be explained.

[0021] The communication terminal 20 includes an operation unit 21, a display unit 22, and a processing unit .

[0022] The operation unit 21 is operated by a user. When the operation unit 21 receives an operation from the user, it outputs an operation signal corresponding to the received operation to the processing unit 23. For example, the operation unit 21 is a touch panel or a button. In an example of the first embodiment, the operation unit 21 is a touch panel that is integrated with the display unit 22. For example, the user can input their own sleep onset time and wake-up time into the communication terminal 20 by operating the operation unit 21. The communication terminal 20 can set the user's sleep onset time and wake-up time in the information processing device 30 by transmitting the input information on the sleep onset time and wake-up time to the information processing device 30.

[0023] The user can select a device 200 (hereinafter referred to as an "operating device") that the user wants to operate by the information processing device 30 by operating the operation unit 21. The communication terminal 20 can set the device 200 to be controlled by the information processing device 30 by transmitting information about the operating device (hereinafter referred to as "device information") selected by the operation unit 21 to the information processing device 30.

[0024] The display unit 22 displays information. For example, the display unit 22 is provided with a touch panel display screen.

[0025] The processing unit 23 includes a processor, a memory, and a communication interface. The processing unit 23 displays information obtained from the information processing device 30 via the third network NW3 on the display unit 22. The processing unit 23 includes a processor, a memory, and a communication interface. The processing unit 23 transmits information (e.g., sleep time, wake-up time, and device information) corresponding to an operation signal obtained from the operation unit 21 to the information processing device 30 via the third network NW3. For example, the function of the processing unit 23 is executed by a pre-installed application.

[0026] When the application is started, the processing unit 23 can acquire biometric information from the information processing device 30 and display the acquired biometric information on the display unit 22. When the application is started, the processing unit 23 acquires environmental data from the information processing device 30. The processing unit 23 can display the acquired environmental data on the display unit 22. The processing unit 23 can display the biometric information and environmental data of the user while he or she is asleep in chronological order on the display unit 22. The processing unit 23 can display the user's current biometric information and environmental data on the display unit 22.

[0027] An example of a schematic configuration of the information processing device 30 according to the first embodiment will be described. The information processing device 30 includes a biological information acquisition unit 31, a sleeping environment acquisition unit 32, a setting unit 33, a storage unit 34, and a control unit 35. The information processing device 30 may be located on the Internet or on a cloud.

[0028] The biometric information acquiring unit 31 acquires biometric information of a user (human body) in the control space 110 via the second network NW2. In the first embodiment, the biometric information acquiring unit 31 acquires the biometric information measured by the biometric information detecting device 400 via the gateway 10.

[0029] The sleeping environment acquisition unit 32 acquires the sleeping environment in the control space 110 via the second network NW2. In the first embodiment, the sleeping environment acquisition unit 32 acquires the environmental data measured by the environment measuring device 300 via the gateway 10.

[0030] The setting unit 33 stores the user's sleep onset time and wake-up time in the storage unit 34 based on information from the communication terminal 20. The setting unit 33 sets the user's sleep onset time and wake-up time. The setting unit 33 stores information about the operating device in the storage unit 34 based on device information from the communication terminal 20. The setting unit 33 sets an operating device from among the multiple devices 200.

[0031] The storage unit 34 stores the biometric information acquired by the biometric information acquisition unit 31 in chronological order. The storage unit 34 stores the environmental data acquired by the sleep environment acquisition unit 32 in chronological order. The storage unit 34 stores information on the user's fall asleep time and wake-up time. The storage unit 34 stores information on the operating device (device information). The storage unit 34 stores information on the user (hereinafter referred to as "user information"). The user information is information on the user who uses the service provided by the information processing device 30, and is registered in advance in the storage unit 34. The user information is associated with authentication information and building information for each user. For example, the authentication information is information for the communication terminal 20 to log in to the information processing device 30 via the third network NW3. For example, the authentication information has the user's identification information (e.g., ID) and password. The building information is information for identifying the building 100. For example, if a user is using building 100-m among multiple buildings 100-1 to 100-n, the user's authentication information is associated with building information 100-m. Note that a user of building 100-m is a person who lives in building 100-m or a person who manages building 100. User authentication is performed using this user information, and the building 100 that the user is using is identified.

[0032] Control unit 35 is connected to device 200 that adjusts the sleep environment via network NW2, and controls device 200 that is set as an operating device. Control unit 35 controls the operating device so that the sleep environment is created according to the biological information during the time period from the sleep onset time to the wake-up time set in storage unit 34.

[0033] 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 that corresponds to the biological information during the time period from the time of falling asleep to the time of waking up. As an example, the control unit 35 adjusts the temperature in the controlled space 110 by controlling the air conditioner 200-1 during the time period from the time of falling asleep to the time of waking up according to the body temperature, which is the biological information acquired by the biological information acquisition unit 31. The information processing device 30 can provide the user with a more comfortable sleep environment.

[0034] The control unit 35 is connected 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 time. The information processing device 30 can enable the user to fall asleep comfortably.

[0035] The control unit 35 is connected via the network NW2 to an opening / closing device 200-3 that opens and closes the opening / closing body in the control space 110. When the current time reaches the time set as the wake-up time, the control unit 35 controls the opening / closing device 200-3 to operate the opening / closing body to an open state. The information processing device 30 can realize a pleasant wake-up for the user.

[0036] The information processing device 30 may be configured with one or more servers. For example, the information processing device 30 may include an application server, a database server, and a client server. For example, the application server includes the functions of a biological information acquisition unit 31, a sleeping environment acquisition unit 32, a setting unit 33, and a control unit 35. For example, the database server stores device information and weather information obtained from the device 200. The client server stores user information of the user. For example, the application server transmits and receives data to and from the database server and the client server using an API (Application Programming Interface).

[0037] For example, the information processing device 30 compares 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 comparison is successful, permits access from the communication terminal 20. Then, the information processing device 30 determines the building 100 that the user is using, for example, based on the user information stored in the storage unit 34.

[0038] The flow of operations in the process of controlling the sleep environment in the information processing device 30 will be described with reference to Fig. 2. In the example shown in Fig. 2, each device 200 in the building 100-m is an operating device.

[0039] The control unit 35 controls the lighting device 200-2 in the control space 110 from a time a predetermined time before the sleep onset time to gradually reduce the illuminance in the control space 110 (step S101). For example, the control unit 35 reduces the illuminance in the control space 110 stepwise or continuously so that the illuminance in the control space 110 reaches a set value at the sleep onset time.

[0040] The control unit 35 determines whether the current time is the sleep onset time (step S102). When the current time reaches the sleep onset time, the control unit 35 transitions to the sleep mode. Upon transition to the sleep mode, the biological information acquisition unit 31 starts acquiring biological information of the user (human body) in the control space 110 (step S103). Furthermore, upon transition to the sleep mode, the sleeping environment acquisition unit 32 starts acquiring environmental data in the control space 110 (step S103).

[0041] The control unit 35 grasps the sleeping environment in the controlled space 110 based on the environmental 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 early in the morning due to radiative cooling. As a result, the user's body temperature drops, and the user may wake up due to the cold. When the control unit 35 detects a drop in the user's body temperature, it raises the temperature in the controlled space 110 in response to that drop. In this way, the control unit 35 can provide a comfortable sleeping environment.

[0042] If the body temperature is high, the user may not be able to cool down properly and may not be able to fall asleep. The control of step S104 may be performed after a predetermined time has elapsed since the user fell asleep. The control unit 35 may lower the air temperature in the controlled space 110 in accordance with the user's body temperature. For example, the control unit 35 may control the air temperature in the controlled space 110 so that the user's body temperature falls within a preset range.

[0043] The control unit 35 determines whether 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 process returns to step S104. On the other hand, if the control unit 35 determines that the current time is the wake-up time, the control unit 35 cancels the sleep mode and increases the illuminance in the controlled space 110 (step S106). For example, if 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, if the control unit 35 determines that the current time is the wake-up time, the control unit 35 may control the opening / closing device 200-3 to open the opening / closing device. By controlling the opening / closing device to the open state, sunlight enters the controlled space 110, and the illuminance in the controlled space 110 increases. In step S106, the control unit 35 may control at least one of the lighting device 200-2 and the opening / closing device 200-3. The information processing device 30 can provide the user with a pleasant wake-up.

[0044] 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 biological information of a human body in the control space 110 via a network NW2. The control unit 35 connects to a device 200 that adjusts a sleep environment via the network NW2 and controls the device 200. The control unit 35 controls the device 200 so that the sleep environment is created according to the biological information acquired by the biological information acquisition unit 31 during the time period from falling asleep to waking up.

[0045] With this configuration, the sleeping environment control system 1 can provide a sleeping environment suited to the user while he or she is sleeping.

[0046] The control unit 35 may adjust the sleep environment, such as the temperature and humidity, in the controlled space 110 by controlling the air conditioner 200-1 in the controlled space 110 in accordance with the biological information. With this configuration, the sleep environment control system 1 can provide a sleep environment that suits the temperature and humidity of the sleeping user.

[0047] The control unit 35 may control the lighting device 200-2 to decrease the illuminance in the controlled space 110 as the current time approaches the time set as the sleep time. The control unit 35 can provide a comfortable sleep environment and sleeping environment by adjusting the temperature and illuminance in the controlled space 110.

[0048] When the current time reaches the wake-up time, the control unit 35 may increase the illuminance in the control space 110 to a predetermined illuminance. With this configuration, the control unit 35 can provide a comfortable wake-up environment.

[0049] The control unit 35 may determine whether or not the user has fallen asleep based on the biological information. In this case, the control unit 35 sets the time at which it is determined that the user has fallen 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 at which the communication terminal 20 is operated as the sleep onset time.

[0050] <Second embodiment> A sleep environment control system 1A according to a second embodiment will be described. In the following description, parts having the same functions as those described in the first embodiment will be given the same names and symbols, and specific descriptions of those functions will be omitted.

[0051] Fig. 3 is a diagram showing an example of the configuration of a sleeping environment control system 1A. The sleeping environment control system 1 differs from the sleeping environment control system 1 of the first embodiment shown in Fig. 1 in that it has a function of suppressing bedsores.

[0052] The load sensor 500 is provided on the electric bed 600. The measurement result of the load sensor 500 is transmitted via the gateway 10 to the information processing device 30A.

[0053] The electric bed 600 has a turning function that assists the human body in turning over while sleeping. The electric bed 600 is controlled by the information processing device 30A via the gateway 10.

[0054] An example of the configuration of a sleeping environment control system 1A according to the second embodiment will now be described. As shown in Fig. 3, the sleeping environment control system 1A includes a gateway 10, a communication terminal 20, and an information processing device 30A. The information processing device 30A includes a biological information acquisition unit 31, a sleeping environment acquisition unit 32, a setting unit 33, a storage unit 34, a determination unit 40, and a control unit 35A. The information processing device 30A may be located on the Internet or in a cloud.

[0055] The determination unit 40 determines whether or not the person sleeping on the electric bed 600 in the control space 110 is likely to have a bedsore, based on the biological information acquired by the biological information acquisition unit 31. However, without being limited to this, the determination unit 40 may determine whether or not the person sleeping on the electric bed 600 is likely to have a bedsore, based on the measurement results of the load sensor 500. For example, the determination unit 40 determines whether or not the user is sleeping on the electric bed 600, based on at least either the biological information or the measurement results of the load sensor 500. The determination unit 40 determines that there is a possibility of a bedsore if the time spent sleeping on the electric bed 600 exceeds a predetermined time.

[0056] The control unit 35A is connected to the electric bed 600 via the network NW2. When the determination unit 40 determines that there is a possibility of bedsore, the control unit 35A controls the electric bed 600 to assist the sleeping person in turning over in bed.

[0057] The process of controlling the sleep environment in the information processing device 30A is the same as that in the first embodiment, and therefore a description thereof will be omitted.

[0058] The sleep environment control system 1A of the second embodiment not only achieves the same effects as the first embodiment, but also determines whether or not there is a possibility of bedsores, and if there is a possibility of bedsores, controls the electric bed 600 to assist the sleeping person in turning over in their sleep. In this way, the sleep environment control system 1A can prevent bedsores.

For example, the information processing device 30 may be a microcontroller. The information processing device 30, 30A may include at least one of a non-volatile semiconductor and a volatile semiconductor. The information processing device 30, 30A may be realized by the processor executing a program. At least some of the components of the information processing device 30 may be realized by hardware, or may be realized by a combination of software and hardware.

[0061] For example, the hardware is at least one of an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), and a GPU (Graphics Processing Unit). The program may be stored in a storage device in advance. The storage device is a non-transitory storage medium.

In this case, the program may be installed in the storage device by attaching the storage medium to a drive device. The storage medium is a non-transitory storage medium. For example, the recording medium is a ROM or the like.

[0062] In the above embodiment, the control unit 35, 35A may control the opening and closing device 200-3 to perform passive ventilation. For example, the control unit 35, 35A may determine whether to open a window and perform passive air conditioning or to perform air conditioning control using the air conditioner 200-1, based on information on the temperature and humidity inside and outside the building, as well as information on the weather, the amount of carbon dioxide, and the amount of carbon monoxide. Furthermore, when passive air conditioning is performed, the control unit 35, 35A may measure the time the window is open, the temperature, and the humidity in chronological order.
