[0014] It should be noted that the drawings are schematic diagrams and are not necessarily strict illustrations. In addition, in the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

[0015] (Embodiment) [composition] The configuration of a control system according to an embodiment will be described.

[0016] FIG. 1 is a block diagram showing a functional configuration of a control system according to an embodiment.

[0017] The control system 10 is a system for improving the quality of sleep, in other words, a sleep support system.

[0018] The control system 10 is installed in a residential facility such as a detached house or an apartment building. The control system 10 is not limited to a residential facility, and may be installed in a care facility, accommodation facility, or the like. A room for people to sleep is provided in the facility, and the room where people sleep may be a bedroom, a child's room, or a living room. A room where people sleep includes not only a room where a person is currently sleeping, but also a room where a person will sleep soon.

[0019] The control system 10 includes a control device 20, air conditioning equipment 60, and a sensor 80. The control system 10 also includes an electric device 30, a distribution board 35, a router 36, and a server 40. The control system 10 also includes an information terminal 95.

[0020] The control device 20, the air conditioning device 60, the sensor 80, the electrical device 30, the distribution board 35, and the router 36 are installed within the facility 70 (more specifically, within the premises of the facility 70), and the server 40 is installed outside the facility 70. The information terminal 95 is located outside the facility 70, but may also be located within the facility 70.

[0021] The sensor 80 is an environmental sensor that detects air quality. The sensor 80 is installed in a room 75 where a person sleeps, and detects air quality such as temperature, humidity, gas concentration, and PM2.5 concentration. The sensor 80 is communicatively connected to the control device 20 via a local communication network. The sensor 80 outputs sensing information detected in the room to the control device 20 as needed or periodically.

[0022] The air conditioning equipment 60 is equipment that adjusts the air quality environment in a room. Examples of the air conditioning equipment 60 include an air conditioner, a humidifier, a ventilator, and an air purifier. The air conditioning equipment 60 is communicatively connected to the control equipment 20 via a local communication network. The air conditioning equipment 60 is registered in the control equipment 20, and the operation of the air conditioning equipment 60 is controlled by the control equipment 20. Note that if the air conditioning equipment 60 is manually operated using a remote controller or the like, this manual operation takes priority. Information about the manual operation is transmitted from the air conditioning equipment 60 to the control equipment 20. The information about the manual operation includes the operation content for adjusting the air quality environment, and also includes information about power on / off.

[0023] The plurality of electrical appliances 30 are IoT (Internet of Things) devices installed in the facility 70. The plurality of electrical appliances 30 includes lighting appliances 32. The plurality of electrical appliances 30 also includes cooking appliances (including a rice cooker, a cooking heater, a microwave oven, and an electric kettle) 33, a refrigerator, and a heat pump water heater. The plurality of electrical appliances 30 also includes electric shading devices 34 such as electric shutters, electric blinds, and electric curtains. In other words, the plurality of electrical appliances 30 includes home appliances. The electrical appliances 30 are communicatively connected to the control device 20 via a local communication network. At least some of the plurality of electrical appliances 30 are registered in the control device 20 and thereby operated and controlled by the control device 20. Note that if the electrical appliance 30 is manually operated using a remote controller or the like, the manual operation takes priority. Information on the manual operation is transmitted from the electrical appliance 30 to the control device 20. The information on the manual operation includes the operation content of the electrical appliance 30 and information on power on / off.

[0024] The distribution board 35 is capable of monitoring the on / off state of the power supply to the air conditioning equipment 60 and the electrical equipment 30. The distribution board 35 has a power measurement function and is also capable of measuring the power consumption (amount of power consumption) in the facility 70. The distribution board 35 is communicatively connected to the control device 20 via a local communication network. The distribution board 35 outputs information relating to the on / off state of the power supply to the air conditioning equipment 60 and the electrical equipment 30 and the power consumption state to the control device 20.

[0025] The control device 20 is a device that can control the sensors 80, the air conditioning devices 60, and the electrical devices 30, as well as monitor their status, and is, for example, a gateway device. The control device 20 may be an EMS (Energy Management System) controller that has an energy management function. The control device 20 is installed, for example, on a wall in a living room.

[0026] Control device 20 of this embodiment controls air conditioning equipment 60 and the like based on information about indoor air quality obtained by sensor 80. Control device 20 includes an operation receiving unit 21, a display unit 22, an information processing unit 23, a memory unit 24, a first communication unit 25, and a second communication unit 26.

[0027] The operation reception unit 21 receives operations from people using the facility 70. The operation reception unit 21 is realized by, for example, a touch panel, but may also be realized by hardware keys or the like.

[0028] The display unit 22 displays an image. The display unit 22 is realized by a display panel such as a liquid crystal panel or an organic EL (Electro-Luminescence) panel. Note that the display unit 22 may be separate from the control device 20.

[0029] The information processing unit 23 performs display processing to display various pieces of information obtained by the information processing unit 23 on the display unit 22. The information processing unit 23 is realized by, for example, a microcomputer, but may also be realized by a processor. The functions of the information processing unit 23 are realized, for example, by the microcomputer or processor constituting the information processing unit 23 executing a computer program stored in the storage unit 24.

[0030] The storage unit 24 is a storage device that stores computer programs and the like executed by the information processing unit 23. The storage unit 24 is realized by, for example, a semiconductor memory.

[0031] The memory unit 24 stores various types of information for improving sleep quality. For example, the memory unit 24 stores information related to the reference values ​​and reference ranges of gas concentrations in the rooms of the facility 70. The memory unit 24 also stores operation history information of the air conditioning equipment 60. The period of the operation history information is, for example, log information for the most recent month, but is not limited to this and may be log information for the most recent week, and the period is not particularly limited. The same applies to the operation history information described below.

[0032] The storage unit 24 also stores information relating to the bedtimes and wake-up times of the users of the control system 10. The various types of information stored in the storage unit 24 will be described in detail in the following operation examples.

[0033] The first communication unit 25 is a communication circuit that enables the control device 20 to communicate with the sensors 80, the air conditioning devices 60, the electrical devices 30, etc. via a local communication network. There are no particular limitations on the communication standard used for communication by the first communication unit 25.

[0034] The second communication unit 26 is a communication circuit for the control device 20 to communicate with the server 40 and the like via the router 36 and the wide area communication network. There are no particular restrictions on the communication standard used for communication by the second communication unit 26.

[0035] The router 36 is, for example, a wireless LAN (Local Area Network) router installed in the facility 70. The router 36 is connected to a wide area communication network such as the Internet, and the control device 20 can be connected to the wide area communication network via the router 36. In FIG. 1 , the plurality of electrical devices 30 are communicatively connected to the control device 20 without going through the router 36, but they may also be communicatively connected to the control device 20 via the router 36.

[0036] The server 40 is a cloud server that acquires the usage status of the plurality of electric appliances 30 from the control device 20 and sends notifications to the control device 20 based on the acquired usage status. The configuration of the server 40 will be described in detail later.

[0037] The information terminal 95 is, for example, a portable information terminal such as a smartphone or a tablet terminal, but may also be a stationary information terminal such as a personal computer. The information terminal 95 has a display unit that displays various information transmitted from the control device 20. Furthermore, the information terminal 95 is capable of receiving operation inputs from the user, similar to the operation receiving unit 21 of the control device 20.

[0038] The control system 10 of this embodiment includes a sensor 80 that detects the indoor air quality of a room 75 where a person sleeps, an air conditioner 60 that adjusts the indoor air quality environment, and a control device 20 that is communicatively connected to the sensor 80 and the air conditioner 60 via a communication network. The control device 20 controls the air conditioner 60 based on information about the indoor air quality obtained by the sensor 80. In this way, controlling the air conditioner 60 based on the information about the indoor air quality can improve the quality of sleep.

[0039] An example of the operation of the control system 10 or the control device 20 will now be described in detail.

[0040] [Example 1] A description will be given of a first operational example of the control system 10. In the first operational example, an example will be described in which the air conditioner 60 is controlled based on the concentration of carbon dioxide (CO2) in the room.

[0041] FIG. 2 is a flowchart of a first operational example of the control system 10. In FIG.

[0042] As shown in FIG. 2, the control device 20 acquires information related to indoor air quality (step S11). The information related to indoor air quality is, for example, information related to indoor temperature, humidity, gas concentration, PM2.5 concentration, etc. The control device 20 acquires the information related to indoor air quality based on sensing information transmitted from the indoor sensor 80. The sensing information may be raw data such as sensor parameters, or processed data generated based on the raw data. The air conditioner 60 in Operation Example 1 acquires information related to the indoor carbon dioxide concentration.

[0043] Next, the control device 20 determines whether the air conditioning equipment 60 is in operation (step S12). For example, the control device 20 determines whether the air conditioning equipment 60 is in operation based on information transmitted from the air conditioning equipment 60 or the distribution board 35.

[0044] If the air conditioning equipment 60 is operating (Yes in S12), the control device 20 determines whether the carbon dioxide concentration has fallen below a reference value (step S13). The reference value is a value that is set in advance and stored in the storage unit 24 of the control device 20. For example, the reference value of the carbon dioxide concentration is set appropriately within the range of 800 ppm or more and 1000 ppm or less.

[0045] If the carbon dioxide concentration is not lower than the reference value (No in S13), the control device 20 continues the operation of the air conditioning device 60 and proceeds to step S19. The control device 20 determines whether or not an operation end signal has been received (S19). If an operation end signal has not been received (No in S19), the process of step S11 is executed from the beginning.

[0046] Control device 20 again acquires information regarding indoor air quality (S11) and determines whether or not air conditioner 60 is operating (S12). In this situation, air conditioner 60 is still operating, so the process proceeds to step S13. Control device 20 determines whether or not the carbon dioxide concentration has fallen below the reference value (S13). If the carbon dioxide concentration has not fallen below the reference value (No in S13), control device 20 repeatedly executes steps S11 to S13 and S19.

[0047] If the carbon dioxide concentration becomes lower than the reference value (Yes in S13), the control device 20 stops the operation of the air conditioning device 60 (step S14). Then, the control device 20 proceeds to step S19 and determines whether or not an operation end signal has been received. If an operation end signal has not been received (No in S19), the control device 20 returns to step S11.

[0048] Control device 20 again acquires information regarding indoor air quality (S11) and determines whether air conditioner 60 is operating (S12). In this situation, air conditioner 60 is stopped, so control proceeds to the next step S15, where control device 20 determines whether the carbon dioxide concentration is equal to or greater than the reference value (S15). If the carbon dioxide concentration is not equal to or greater than the reference value (No in S15), control device 20 proceeds to step S19 and repeatedly executes the processes of steps S11, S12, S15, and S19.

[0049] If the carbon dioxide concentration is equal to or greater than the reference value (Yes in S15), the control device 20 determines whether a predetermined time has elapsed since the previous shutdown (step S16). The predetermined time is a time that is set and stored in advance in the storage unit 24, and is set appropriately within the range of, for example, 1 minute to 10 minutes.

[0050] If the predetermined time has elapsed (Yes in S16), the process proceeds to step S18, where the control device 20 starts up the air conditioning device 60 (S18). The control device 20 then proceeds to step S19, where it determines whether or not an operation end signal has been received (step S19). If an operation end signal has not been received (No in S19), the process of step S11 is executed from the beginning.

[0051] On the other hand, if the predetermined time has not elapsed (No in S16), the control device 20 determines whether the carbon dioxide concentration has become higher than the reference value by a predetermined value or more (step S17). The predetermined value is, for example, a set value for determining whether the carbon dioxide concentration has significantly exceeded the reference value, and is appropriately set within a range of 500 ppm to 3000 ppm with the reference value as the base.

[0052] If the carbon dioxide concentration is not higher than the reference value by a predetermined value or more (No in S17), the control device 20 proceeds to step S19. Then, the control device 20 repeatedly executes the processes of steps S11, S12, S15, S16, S17 and S19.

[0053] On the other hand, if the carbon dioxide concentration is higher than the reference value by a predetermined value or more (Yes in S17), the control device 20 proceeds to step S18, and starts up the air conditioning equipment 60 (S18). The control device 20 then proceeds to step S19, and determines whether or not an operation end signal has been received (step S19). If an operation end signal has not been received (No in S19), the control device 20 executes the processing of step S11 from the beginning. If an operation end signal has been received (Yes in S19), the control device 20 stops the operation of the air conditioning equipment 60. In operation example 1, these steps S11 to S19 are executed repeatedly.

[0054] In this operation example, the control device 20 operates the air conditioning device 60 when the carbon dioxide concentration detected by the sensor 80 is equal to or higher than a reference value. Furthermore, the control device 20 stops the air conditioning device 60 if the carbon dioxide concentration falls below the reference value after operating the air conditioning device 60. The control device 20 does not start the air conditioning device 60 if the carbon dioxide concentration does not rise above the reference value by a predetermined value or more within a predetermined time after stopping the air conditioning device 60. On the other hand, the control device 20 starts the air conditioning device 60 if the carbon dioxide concentration rises above the predetermined value or more within a predetermined time. By controlling the air conditioning device 60 in this manner, the carbon dioxide concentration in the room can be maintained at an appropriate level. This can improve the quality of sleep.

[0055] [Example 2] A second operational example of the control system 10 will be described. In the second operational example, the air conditioner 60 is controlled in response to the lighting device 32 being turned on.

[0056] The control system 10 includes a lighting device 32, which is an electrical device 30. The lighting device 32 is installed in a room 75 where the user sleeps, and is registered in advance in the control device 20 as a device installed in the room where the user sleeps. The lighting device 32 is communicatively connected to the control device 20 via a local communication network.

[0057] FIG. 3 is a flowchart of a second operation example of the control system 10.

[0058] As shown in FIG. 3, control device 20 acquires information indicating that lighting device 32 was turned on within a range of one hour before and after a preset bedtime (step S21).

[0059] The preset bedtime is the user's planned bedtime, and is set and saved in advance in the storage unit 24 of the control device 20. The range of one hour around the bedtime is a period with a certain degree of leeway from the bedtime, for example, a period including a leeway of ±1 hour from the bedtime. The bedtime is set and input, for example, through the operation reception unit 21 of the control device 20 or the information terminal 95. The bedtime may be set by clock setting or timer setting. The control device 20 obtains information indicating that the lighting device 32 has been turned on from a signal transmitted from the lighting device 32 or from a signal transmitted from the distribution board 35.

[0060] When the control device 20 acquires the information indicating that the lighting device 32 has been turned on in step S21, the control device 20 starts up the air conditioning device 60 (step S22). At this time, the control device 20 controls the air conditioning device 60 based on the information related to the indoor air quality.

[0061] In this operation example, when the control device 20 determines that the lighting device 32 is turned on within a range of one hour before or after the preset bedtime, the control device 20 controls the air conditioner 60 based on information about the indoor air quality. In this way, by controlling the air conditioner 60 when it is determined that the lighting device 32 is turned on within a range of one hour before or after the bedtime, the user can sleep in an environment with appropriate air quality. This can improve the quality of the user's sleep.

[0062] If the control device 20 does not receive an input to turn off the power to the lighting device 32 for a certain period of time, the control device 20 may gradually dim the brightness of the lighting device 32 and turn it off after a certain period of time has elapsed since the lighting device 32 was turned on or after a certain period of time has elapsed since the air conditioning device 60 was started.

[0063] [Example 3] A description will be given of a third operational example of the control system 10. In the third operational example, a change in indoor air quality is predicted and presented to the user.

[0064] Air conditioning equipment 60 is installed in room 75 where the user sleeps, and is registered in advance in control device 20 as equipment installed in the room where the user sleeps. Storage unit 24 of control device 20 stores operation history information of air conditioning equipment 60 and information related to the air quality in the room in association with each other.

[0065] FIG. 4 is a flowchart of a third operation example of the control system 10.

[0066] As shown in FIG. 4, the control device 20 acquires information about the indoor air quality (step S31).

[0067] Next, the control device 20 predicts a change in the indoor air quality over time based on the information on the indoor air quality (step S32). As the change in the indoor air quality, the control device 20 predicts a change in the air quality when the air conditioner 60 is not operated and a change in the air quality when the air conditioner 60 is operated.

[0068] Next, control device 20 causes the display unit to display the predicted result (step S33). Control device 20 may cause the display unit 22 of control device 20 to display the predicted result, or may cause the display unit of information terminal 95 to display the predicted result.

[0069] FIG. 5 is a diagram showing an example of a display screen in the third operation example.

[0070] Figure 5 shows the change in carbon dioxide concentration and the change in house dust amount when the air conditioning equipment 60 is operated. Figure 5 also shows the change in carbon dioxide concentration and the change in house dust amount when the air conditioning equipment 60 is not operated. These changes in carbon dioxide concentration and changes in house dust amount are derived, for example, based on the relationship between the operation history information of the air conditioning equipment 60 stored in the memory unit 24 and information related to indoor air quality.

[0071] Next, the control device 20 determines whether or not an operation input instructing the air conditioning device 60 to operate has been received (step S34). The control device 20 may receive the operation input from the operation receiving unit 21, or may receive the operation input via the information terminal 95.

[0072] If the control device 20 receives the above operation input (Yes in S34), it operates the air conditioning equipment 60 (step S35). If the control device 20 does not receive the operation input (No in S34), it ends the process without operating the air conditioning equipment 60.

[0073] In this operational example, the control device 20 predicts changes in indoor air quality over time based on information about the indoor air quality, and displays the information about the changes in air quality on the display unit. Then, when an input commanding operation of the air conditioner 60 is received, the control device 20 operates the air conditioner 60. By displaying information about changes in air quality in this way and operating the air conditioner 60 when an input commanding operation of the air conditioner 60 is received, an environment with air quality that meets the user's desire can be created. This can improve the user's sleep quality.

[0074] [Example 4] A description will be given of a fourth operational example of the control system 10. In the fourth operational example, an example will be described in which an evaluation result regarding the quality of air quality is presented to the user.

[0075] Evaluation criteria regarding the quality of indoor air are stored in advance in the storage unit 24 of the control device 20. The storage unit 24 also stores proposal information for improving the air quality.

[0076] FIG. 6 is a flowchart of a fourth operational example of the control system 10.

[0077] As shown in FIG. 6, the control device 20 acquires information about the indoor air quality (step S41).

[0078] Next, control device 20 assigns a score to the evaluation of air quality for each of a plurality of rooms based on the information related to the indoor air quality (step S42).

[0079] Next, control device 20 causes the display unit to display the scoring result (step S43). Control device 20 may cause display unit 22 of control device 20 to display the scoring result, or may cause information terminal 95 to display the same.

[0080] FIG. 7 is a diagram showing an example of a display screen in the fourth operation example.

[0081] Figure 7 shows the results of air quality evaluations of a living room and a bedroom, which are examples of multiple rooms. The figure also shows scores for carbon dioxide concentration, house dust, and odor as evaluation items. The air quality environment is a comprehensive evaluation of carbon dioxide concentration, house dust, and odor. These displays visualize the good and bad state of air quality in each room.

[0082] The figure also shows suggested information for improving the evaluation results. For example, the control device 20 suggests additional air conditioning equipment that should be activated to prevent the air quality from deteriorating. The control device 20 may periodically share the evaluation results for each room, and may provide advice on cleaning and ventilation of the room, or may encourage the purchase of additional equipment.

[0083] In this operation example, the control device 20 displays, on the display unit, the evaluation results regarding the quality of air quality for each of the multiple rooms 75 provided in the facility 70, and suggested information corresponding to the evaluation results. Displaying the evaluation results and suggested information in this manner can lead to improved sleep quality and health promotion for the user.

[0084] [Example 5] A description will be given of a fifth operational example of the control system 10. In the fifth operational example, a bedtime of the user is estimated and the air conditioner 60 is started before the bedtime.

[0085] The user's bedtime is set and stored in the memory unit 24 of the control device 20. The memory unit 24 also stores operation history information of the air conditioning equipment 60. The operation history information of the air conditioning equipment 60 is information related to the operation time and operation control content of the air conditioning equipment 60, and the operation information is digitized for each day of the week, for example. Note that the operation history information may also be digitized for each weekday and holiday.

[0086] FIG. 8 is a flowchart of a fifth operation example of the control system 10.

[0087] 8, the control device 20 derives the scheduled start time of the air conditioning device 60 based on the bedtime set by the user and operation history information of the air conditioning device 60 (step S51). The scheduled start time is derived based on data for each day of the week or for each weekday and holiday. The control device 20 may estimate the user's bedtime based on the bedtime set by the user and operation history information of the air conditioning device 60, and set the scheduled start time to a few minutes before the estimated time.

[0088] The control device 20 starts up the air conditioner 60 at the scheduled start-up time derived in step S51 (step S52). The control device 20 controls the air conditioner 60 based on information related to the indoor air quality.

[0089] In this operation example, the control device 20 estimates the bedtime of the user who uses the air conditioner 60 based on a preset bedtime and operation history information of the air conditioner 60, and starts the air conditioner 60 before bedtime. By starting the air conditioner 60 before bedtime in this way, the user can sleep in an environment with appropriate air quality. This can improve the quality of the user's sleep.

[0090] [Example 6] A sixth operation example of the control system 10 will be described. In the sixth operation example, an example in which the air conditioner 60 is operated based on vital sign information of a user wearing the wearable terminal 90 will be described.

[0091] Fig. 9 is a block diagram showing another example of the functional configuration of the control system according to the embodiment, which is a block diagram common to operation examples 6 to 10 described below.

[0092] 9 includes, similarly to FIG 1, a control device 20, an air conditioning device 60, a sensor 80, an electric device 30, a distribution board 35, a router 36, a server 40, and an information terminal 95. The control system 10 further includes a wearable terminal 90.

[0093] The wearable terminal 90 is worn by a user who uses the control system 10. The wearable terminal 90 detects vital information related to the person's heart rate, blood pressure, body temperature, and movement. In this example, the wearable terminal 90 detects vital information while the person is sleeping. The wearable terminal 90 is communicatively connected to the control device 20 via a local communication network. The wearable terminal 90 outputs vital information of the person wearing the wearable terminal 90 to the control device 20. The wearable terminal 90 also has a display unit that displays various information transmitted from the control device 20.

[0094] The server 40 shown in FIG. 9 includes a communication unit 41, an information processing unit 42, and a storage unit 43.

[0095] The communication unit 41 is a communication circuit that enables the server 40 to communicate with each of the control device 20, the wearable terminal 90, the information terminal 95, and the control device 20 via a wide area communication network. The communication unit 41 may be a wired communication circuit that performs wired communication, or a wireless communication circuit that performs wireless communication.

[0096] The information processing unit 42 processes information related to notifications to the control device 20, the information terminal 95, and the wearable terminal 90. The information processing unit 42 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit. The information processing unit 42 includes, as functional components, an acquisition unit, a determination unit, a judgment unit, a notification unit, and a control unit (not shown). The functions of the acquisition unit, the determination unit, the judgment unit, the notification unit, and the control unit are realized by hardware such as a microcomputer or a processor constituting the information processing unit 42 executing a computer program (software) stored in the storage unit 43.

[0097] The storage unit 43 is a storage device that stores information necessary for the above information processing. The information stored in the storage unit 43 includes a computer program executed by the information processing unit 42. The storage unit 43 is realized by, for example, an HDD (Hard Disc Drive), but may also be realized by a semiconductor memory.

[0098] The storage unit 43 stores general attribute data, which is attribute data of ordinary people, and reference operation information, which is operation information of air conditioners corresponding to the general attribute data, in association with each other.

[0099] Furthermore, the storage unit 24 of the control device 20 stores a history of the user's vital information and a reference range of the vital information. The reference range of the vital information is set to a predetermined range based on the average value of the user's vital information. The predetermined range is, for example, a range within which the user's physical and mental state is considered normal.

[0100] FIG. 10 is a flowchart of a sixth operation example of the control system 10 according to the embodiment.

[0101] 10, the control device 20 acquires vital information of the user from the wearable terminal 90 (step S61). The vital information is information related to the heart rate, blood pressure, body temperature, and movement of the person wearing the wearable terminal 90. The control device 20 acquires the vital information when the person wearing the wearable terminal 90 is sleeping.

[0102] The control device 20 determines whether or not the vital information acquired in step S61 is a value that differs from the reference range stored in the storage unit 24 (step S62).

[0103] If the vital information is not a value that differs from the reference range (No in S62), the control device 20 ends the process without operating the air conditioning device 60. If the vital information is different from the reference range (Yes in S62), the control device 20 operates the air conditioning device 60 (step S63).

[0104] The control system 10 in this operational example includes a wearable device 90 that detects vital information related to a person's heart rate, blood pressure, body temperature, and movement while they are sleeping. The wearable device 90 outputs the vital information of the person wearing the wearable device 90 to the control device 20. The control device 20 sets a reference range for the vital information of the person wearing the wearable device 90 based on the vital information. If the vital information of the person wearing the wearable device 90 while they are sleeping differs from the reference range, the control device 20 operates the air conditioning device 60. By controlling the air conditioning device 60 in this way when the vital information differs from the reference range, the quality of the user's sleep can be improved.

[0105] The control device 20 may accumulate this vital information, operation information and performance data of the air conditioner 60, learn the conditions under which the user can sleep comfortably based on the accumulated data, and use this data when controlling the air conditioning thereafter. In other words, the control device 20 may learn the relationship between the vital information and operation information of the air conditioner 60, and control the air conditioner 60 based on the results of learning this relationship. By learning the vital information during sleep and the operation information of the air conditioner 60, it is possible to improve the quality of sleep tailored to the individual user.

[0106] [Example 7] A description will be given of a seventh operational example of the control system 10. In the seventh operational example, an example will be described in which the air conditioner 60 is operated based on the attributes of the user.

[0107] The memory unit 43 of the server 40 stores general attribute data indicating the attributes of ordinary people, and reference operation information, which is operation information of air conditioners corresponding to the general attribute data. The ordinary people's attribute data is data indicating the characteristics of each of a plurality of ordinary people, and includes, for example, data on the height, weight, age, gender, etc. of the plurality of ordinary people. The reference operation information is stored corresponding to a plurality of ordinary people so that it can be applied to various patterns.

[0108] The storage unit 24 of the control device 20 stores individual attribute data that indicates the individual attributes of users who use the air conditioning equipment 60. The individual attribute data is data that indicates the characteristics of individual users, and includes data on the user's height, weight, age, sex, etc., for example.

[0109] FIG. 11 is a flowchart of a seventh operation example of the control system 10 according to the embodiment.

[0110] As shown in FIG. 11, the control device 20 acquires the user's vital sign information and the current operating status of the air conditioner 60 (step S71).

[0111] The control device 20 transmits the user's vital information, individual attribute data, and the current operating status of the air conditioner 60 to the server 40 (step S72).

[0112] The server 40 compares and analyzes the individual attribute data and the current operating status of the air conditioning equipment 60 transmitted from the control device 20 with the general attribute data and reference operation information stored in the storage unit 43 (step S73). The server 40 derives, from the reference operation information, operation information that would be comfortable for an average person with characteristics similar to the user, as recommended operation information. The server 40 then transmits the recommended operation information for operating the air conditioning equipment 60 to the control device 20 (step S74). The server 40 may also derive the recommended operation information using the user's vital sign information.

[0113] The control device 20 controls the air conditioner 60 based on the recommended operation information transmitted from the server 40 (step S75).

[0114] In the control system 10 of this operation example, the server 40 outputs recommended operation information for operating the air conditioning equipment 60 to the control device 20 based on individual attribute data indicating the attributes of the person using the air conditioning equipment 60, the current operation status of the air conditioning equipment 60, as well as general attribute data and reference operation information. The control device 20 operates the air conditioning equipment 60 based on the recommended operation information. By controlling the air conditioning equipment 60 based on the recommended operation information in this way, the user's sleep quality can be improved. Furthermore, even a user who has just purchased the control device 20 can obtain operation information that people with similar characteristics to the user find comfortable, so the user's sleep quality can be easily improved.

[0115] [Example 8] A description will be given of an eighth operational example of the control system 10. In the eighth operational example, an example will be described in which the lighting device 32 is turned on when the user sits up from a sleeping state.

[0116] The control system 10 includes lighting devices 32 communicatively coupled to a control device 20 via a local communication network.

[0117] FIG. 12 is a flowchart of an eighth operation example of the control system 10 according to the embodiment.

[0118] As shown in FIG. 12, the control device 20 acquires vital information of a user who is sleeping and wearing the wearable terminal 90 (step S81).

[0119] Based on the vital sign information, control device 20 acquires information indicating that the user has sat up from a sleeping state (step S82). Control device 20 can acquire information regarding the depth or lightness of the person's sleep from changes in the heart rate, which is part of the vital sign information. Control device 20 can also acquire information regarding whether the person has sat up, based on an acceleration sensor provided in wearable terminal 90. Based on this information, control device 20 determines whether the user has sat up.

[0120] When the control device 20 acquires the information indicating that the user has sat up in step S82, the control device 20 turns on the lighting device 32 (step S83). The control device 20 may perform dimming control so that the lighting device 32 lights up gradually.

[0121] In this operation example, when it is determined based on the vital sign information that the user wearing the wearable terminal 90 has moved from a sleeping state to a sitting up state, the control device 20 turns on the lighting device 32. This can help the user to avoid falling when, for example, getting up from bed.

[0122] [Example 9] A ninth operation example of the control system 10 will be described. In the ninth operation example, information about the health of the user is output based on vital information of the user and operation history information of the electric appliance 30.

[0123] The control system 10 includes a cooking appliance 33, which is an electric appliance 30. The cooking appliance 33 is installed in a facility 70 and is pre-registered in the control device 20 as an appliance that a user will use for cooking. The cooking appliance 33 is communicatively connected to the control device 20 via a local communication network.

[0124] The memory unit 24 of the control device 20 stores operation history information of the cooking appliance 33. Note that the operation history information stored in the memory unit 24 is not limited to the operation history information of the cooking appliance 33, and may also store operation history information of a refrigerator, a heat pump water heater, etc.

[0125] FIG. 13 is a flowchart of a ninth operation example of the control system 10 according to the embodiment.

[0126] 13, control device 20 acquires operation history information of electric device 30 used by a user and vital information of the user (step S91). Note that the user shown here is a person who uses wearable terminal 90.

[0127] Next, the control device 20 estimates a change in the health condition of the user who owns the wearable terminal 90 based on the operation history information of the electric device 30 and the vital sign information acquired in step S91 (step S92).

[0128] The control device 20 displays the change in the user's health condition (step S93). The control device 20 outputs information about the health of the person who owns the wearable device 90 to at least one of the display unit 22 of the control device 20 and the display unit of the wearable device 90. The display on the wearable device 90 is performed, for example, using a predetermined application program (hereinafter referred to as a predetermined app) that is pre-installed on the wearable device 90. The notification destination, such as the ID of the predetermined app, is stored in the storage unit 24 when the user registers to use the predetermined app.

[0129] FIG. 14 is a diagram showing an example of a display screen in the ninth operational example.

[0130] 14 shows information about a person's health. The figure shows the cumulative number of days that a rice cooker and a cooking heater have been used as examples of cooking appliances 33. The figure also shows information indicating the user's health level.

[0131] The information about a person's health may include at least one of the following: what the person who owns the wearable device 90 is continuously doing to stay healthy, what has been improved or achieved in terms of health, and information about advice about the person's health. By visualizing changes in the user's health status as shown in Fig. 14, advice linked to specific daily actions can be provided in an interactive format to promote health promotion.

[0132] In this operation example, control device 20 acquires operation history information of electrical device 30 used by the person who owns wearable terminal 90 and vital sign information of the person wearing wearable terminal 90, and outputs information about the health of the person who owns wearable terminal 90 based on the operation history information and the vital sign information. Outputting information about a person's health in this way can lead to an improvement in the quality of sleep and promotion of the user's health.

[0133] [Example 10] A description will be given of an operation example 10 of the control system 10. In the operation example 10, an example will be described in which the electric light blocking device 34 is changed from the closed state to the open state when a person is about to get up.

[0134] The control system 10 includes an electric shading device 34, which is an electrical device 30. The electric shading device 34 is installed in a facility 70 or a room 75, and is registered in advance in the control device 20 as a device to be used by a user. The electric shading device 34 is communicatively connected to the control device 20 via a local communication network.

[0135] The storage unit 24 of the control device 20 stores the wake-up time of the user in advance.

[0136] FIG. 15 is a flowchart of an operation example 10 of the control system 10 according to the embodiment.

[0137] As shown in FIG. 15, the control device 20 acquires vital information of a user who is sleeping and wearing the wearable terminal 90 (step S101).

[0138] Control device 20 determines whether the user is in a physical state that allows the user to wake up based on the vital information (step S102). Specifically, control device 20 determines whether the user's body is in a physical state that allows the user to wake up at a preset wake-up time. Control device 20 acquires information, such as whether the person is in a deep sleep, a light sleep, or a drowsy sleep state, from changes in heart rate, which is part of the vital information, and can determine whether the person is in a physical state that allows the user to wake up.

[0139] If the control device 20 determines that the user is in a physical state to wake up at the preset wake-up time (Yes in S102), the control device 20 changes the electric light blocking device 34 from the closed state to the open state (step S103). If the control device 20 determines that the user is not in a physical state to wake up (No in S102), the control device 20 does not operate the electric light blocking device 34 and keeps it in the closed state.

[0140] In this operation example, when the control device 20 determines based on the vital sign information that the person wearing the wearable device 90 is in a physical state that will cause them to wake up at a preset wake-up time, the control device 20 changes the electric light blocking device 34 from the closed state to the open state. This can support the user in waking up so that the user can be woken up comfortably by natural light.

[0141] [Effects, etc.] Hereinafter, examples of inventions that can be obtained from the disclosure of this specification will be given, and the effects and the like that can be obtained from these inventions will be explained.

[0142] The control system 10 of the first invention includes a sensor 80 that detects the indoor air quality of a room 75 where a person sleeps, an air conditioning device 60 that adjusts the indoor air environment, and a control device 20 that is communicatively connected to the sensor 80 and the air conditioning device 60 via a communication network. The control device 20 controls the air conditioning device 60 based on information about the indoor air quality obtained by the sensor 80.

[0143] In this way, by controlling the air conditioner 60 based on information about the indoor air quality, the quality of sleep can be improved.

[0144] The control system 10 of invention 2 is the control system according to invention 1, in which the sensor 80 detects the carbon dioxide concentration of the air quality. The control device 20 operates the air conditioning device 60 when the carbon dioxide concentration detected by the sensor 80 is equal to or higher than a reference value, stops the air conditioning device 60 when the carbon dioxide concentration falls below the reference value after operating the air conditioning device 60, and does not start the air conditioning device 60 if the carbon dioxide concentration does not become higher than the reference value by a predetermined value or more within a predetermined time after stopping the air conditioning device 60.

[0145] By controlling the air conditioner 60 in this way, the carbon dioxide concentration in the room can be maintained at an appropriate level, thereby improving the quality of sleep.

[0146] The control system 10 of Invention 3 is the control system according to Invention 1, further including a lighting device 32 installed in a room. The lighting device 32 is communicatively connected to the control device 20 via a communication network. When the control device 20 determines that the lighting device 32 is turned on within a range of one hour before and after a preset bedtime, the control device 20 controls the air conditioning device 60 based on information about the indoor air quality.

[0147] In this way, by controlling the air conditioner 60 when it is determined that the lighting device 32 is turned on within an hour before or after bedtime, the user can sleep in an environment with appropriate air quality, thereby improving the quality of the user's sleep.

[0148] The control system 10 of Invention 4 is a control system according to any one of Inventions 1 to 3, in which the control device 20 predicts changes in the indoor air quality over time based on information relating to the indoor air quality, and causes the display unit to display information relating to the changes in air quality.

[0149] This allows the user to be appropriately notified of information regarding changes in indoor air quality.

[0150] The control system 10 of Invention 5 is the control system described in Invention 4, and the control device 20 predicts, as changes in indoor air quality, changes in air quality when the air conditioning device 60 is not operated and changes in air quality when the air conditioning device 60 is operated.

[0151] This allows the user to easily decide whether or not to operate the air conditioner 60. Therefore, an environment with air quality that meets the user's desire can be created, thereby improving the quality of the user's sleep.

[0152] The control system 10 of Invention 6 is the control system described in Invention 5, in which the control device 20 displays information regarding changes in air quality on the display unit, and then operates the air conditioning equipment 60 when it receives an input instructing the air conditioning equipment 60 to operate.

[0153] In this way, by operating the air conditioner 60 when an input instructing the operation of the air conditioner 60 is received, an environment with air quality that meets the user's desire can be created, thereby improving the quality of the user's sleep.

[0154] The control system 10 of Invention 7 is a control system according to any one of Inventions 1 to 6, and the control device 20 causes the display unit to display the evaluation results regarding the quality of the air quality of each of multiple rooms in the facility 70, as well as proposal information corresponding to the evaluation results.

[0155] Displaying the evaluation results and suggested information in this manner can lead to improvements in the quality of the user's sleep and promotion of health.

[0156] The control system 10 of Invention 8 is the control system described in Invention 1, in which the control device 20 estimates the bedtime of a user who uses the air conditioning device 60 based on a preset bedtime and operation history information of the air conditioning device 60, and starts the air conditioning device 60 before the bedtime.

[0157] By starting the air conditioner 60 before bedtime in this way, the user can sleep in an environment with appropriate air quality, thereby improving the quality of the user's sleep.

[0158] The control system 10 of Invention 9 is the control system according to Invention 1, further comprising a wearable device 90 that detects vital information related to a person's heart rate, blood pressure, body temperature, and movement while sleeping. The wearable device 90 outputs the vital information of the person wearing the wearable device 90 to the control device 20. The control device 20 sets a reference range for the vital information of the person wearing the wearable device 90 based on the vital information, and operates the air conditioning device 60 when the vital information of the person wearing the wearable device 90 while sleeping is a value different from the reference range.

[0159] In this way, when the vital information is different from the reference range, the air conditioner 60 is controlled, thereby improving the quality of sleep of the user.

[0160] The control system 10 of invention 10 is the control system described in invention 9, in which the control device 20 learns the relationship between vital information and operation information of the air conditioning equipment 60, and controls the air conditioning equipment 60 based on the learned results of the relationship.

[0161] This allows the quality of sleep to be improved in accordance with the individual user.

[0162] The control system 10 of Invention 11 is the control system according to Invention 9, further comprising a server 40 that stores general attribute data indicating the attributes of ordinary people and reference operation information, which is operation information of air conditioning equipment corresponding to the general attribute data. The server 40 and the control device 20 are communicatively connected via a communication network.

The control device 20 operates the air conditioning equipment 60 based on the recommended operation information.

[0163] In this way, controlling the air conditioner 60 based on the recommended operation information can improve the quality of the user's sleep. Furthermore, even for a user who has just purchased the control device 20, the control device 20 can provide operation information that would be comfortable for someone with similar characteristics to the user, so the quality of the user's sleep can be easily improved.

[0164] A control system (10) of a twelfth aspect of the present invention is the control system according to any one of the ninth to eleventh aspects of the present invention, further comprising a lighting device (32) communicatively connected to the control device (20) via a communication network. The control device (20) turns on the lighting device (32) when it determines, based on vital sign information, that the user wearing the wearable terminal (90) has moved from a sleeping state to an upright state.

[0165] This can help the user to avoid falling when getting up from bed, for example.

[0166] The control system 10 of invention 13 is a control system according to any one of inventions 9 to 12, in which the control device 20 acquires operation history information of the electrical device 30 used by the person who owns the wearable terminal 90 and vital sign information of the person wearing the wearable terminal 90, and outputs information relating to the health of the person who owns the wearable terminal 90 based on the operation history information and the vital sign information.

[0167] Outputting information related to a person's health in this way can lead to an improvement in the quality of the user's sleep and promotion of their health.

[0168] The control system 10 of invention 14 is the control system described in invention 13, in which the control device 20 outputs information about the health of the person who owns the wearable terminal 90 to at least one of the display unit 22 of the control device 20 and the display unit of the wearable terminal 90.

[0169] This allows changes in the user's health condition to be visualized, which can lead to improvements in the quality of the user's sleep and promotion of health.

[0170] The control system 10 of invention 15 is the control system according to any one of inventions 9 to 14, further comprising an electric shading device 34 that is communicatively connected to the control device 20 via a communication network. The control device 20 changes the electric shading device 34 from a closed state to an open state when it determines, based on vital sign information, that the person wearing the wearable terminal 90 is in a physical state that will cause them to wake up at a preset wake-up time.

[0171] This can support the user in waking up by allowing the user to wake up comfortably in natural light.

[0172] The control device 20 of the invention 16 includes a communication unit (e.g., a first communication unit 25) that communicates with an environmental sensor provided in a room 75 where a person sleeps and with an air conditioning device 60 provided in the room, and an information processing unit 23 that controls the air conditioning device 60 via the communication unit. The information processing unit 23 acquires information relating to the air quality in the room from the environmental sensor via the communication unit, and controls the air conditioning device 60 based on the information.

[0173] In this way, by controlling the air conditioner 60 based on information about the indoor air quality, the quality of sleep can be improved.
