[0010] As shown in FIG. 1, the control system according to the present embodiment includes an environmental sensor 2, a plurality of devices 3 installed in a building H, a terminal device 5, and a cloud server 1. The plurality of devices 3 include, for example, an air conditioner 3A and a ventilator 3B. The plurality of devices 3 are each connected to a local network NW2 constructed in the building H. The local network NW2 is connected to a wide area network NW1 via a broadband router (hereinafter referred to as "BBR") 42. The cloud server 1 and the terminal device 5 can communicate with each other via the wide area network NW1, and the cloud server 1 can communicate with the environmental sensor 2 and the devices 3 via the wide area network NW1 and the local network NW2. A weather server 6 is connected to the wide area network NW1. The local network NW2 is, for example, a wired LAN (Local Area Network) or a wireless LAN, and the wide area network NW1 is, for example, the Internet.

[0011] When the weather server 6 acquires air quality request information including regional information indicating the region where the building H is located, the weather server 6 generates air quality information including information indicating the temperature, humidity, PM2.5 concentration, and pollen concentration in the region where the building H is located, which is indicated by the regional information included in the acquired air quality request information. The weather server 6 then transmits the generated air quality information to the sender of the air quality request information. When the weather server 6 acquires weather information request information transmitted from the cloud server 1, for example, the weather server 6 generates air quality information based on the regional information included in the acquired weather information request information, and transmits the generated air quality information to the cloud server 1.

[0012] The air conditioner 3A has an environmental sensor (not shown) that measures the air quality inside the building H. The environmental sensor that measures the air quality inside the building of the air conditioner 3A consists of a temperature sensor, a humidity sensor, etc. provided in an indoor unit installed inside the building H.

[0013] The environmental sensor 2 measures, for example, the temperature, humidity, and CO 2 The environmental sensor 2 is a sensor that measures air quality such as concentration, PM2.5 level, pollen concentration level, etc. The environmental sensor 2 transmits air quality information indicating the measured air quality to the cloud server 1 every time a preset information transmission time arrives.

[0014] As shown in Fig. 2, the cloud server 1 includes a CPU (Central Processing Unit) 101, a main memory unit 102, an auxiliary memory unit 103, a communication unit 106, a clock unit 108, and a bus 109 connecting these units to each other. The CPU 101 is, for example, a multi-core processor. The main memory unit 102 has a volatile memory such as a RAM (Random Access Memory) and is used as a working area for the CPU 101. The auxiliary memory unit 103 is composed of a large-capacity non-volatile memory and stores programs for realizing various functions of the cloud server 1. The communication unit 106 is connected to a wide area network NW1. The clock unit 108 has, for example, an RTC (Real Time Clock) and notifies the CPU 101 of the clocked time information.

[0015] The CPU 101 reads out the program stored in the auxiliary storage unit 103 into the main storage unit 102 and executes it, thereby functioning as an operating state acquisition unit 111, an operating state notification unit 112, an air quality acquisition unit 113, a control mode notification unit 114, a function classification acquisition unit 115, a selected controllable mode specification unit 116, a selected controllable mode notification unit 120, a control mode selection unit 117, an equipment control unit 118, and a control mode setting acquisition unit 119, as shown in Fig. 3. The auxiliary storage unit 103 shown in Fig. 2 also has an operating state storage unit 131, an air quality storage unit 132, a control mode storage unit 133, a function classification storage unit 134, and a selected control mode storage unit 135, as shown in Fig. 3. The operating state storage unit 131 stores operating state identification information indicating the operating state of each of the multiple equipment 3 in association with equipment identification information for identifying the equipment 3, as shown in Fig. 4(A), for example. Furthermore, the operation state storage unit 131 stores device identification information of the multiple devices 3 in association with user identification information of a user who owns the multiple devices 3. Here, as the device identification information, for example, a MAC (Media Access Control) address assigned to each device 3 can be adopted. As the user identification information, an email address or a user ID registered by the user in the cloud server 1 can be adopted. In the example shown in FIG. 4(A), the air conditioner 3A and the ventilator 3B identified by the device identification information IDE[2] and IDD[3] are in heat exchange ventilation and heating operation, respectively, identified by the operation state identification information IDM[2] and IDM[3].

[0016] 4(B), the air quality storage unit 132 stores air quality information indicating the air quality inside and outside the building H in which the device 3 is installed, in association with information source identification information indicating the source from which the air quality information was obtained. The air quality storage unit 132 also stores the air quality information in association with the user identification information of the user residing in the building H corresponding to the information. Here, the air quality information includes indoor temperature information and indoor humidity information indicating the temperature and humidity inside the building H, and CO 2 Shows concentration of CO 2The air quality information includes outdoor temperature information and outdoor humidity information indicating the temperature and humidity outside the building H, PM2.5 concentration information indicating the concentration of PM2.5, and pollen concentration information indicating the concentration of pollen. In the example shown in FIG. 4(B), indoor temperature information, indoor humidity information, CO 2 It indicates that concentration information, outdoor temperature information, and outdoor humidity information are acquired. It also indicates that indoor temperature information and indoor humidity information are acquired from the environmental sensor of the air conditioner 3A identified by the information source identification information IDS[1]. It also indicates that outdoor temperature information, outdoor humidity information, PM2.5 concentration information, and pollen concentration information are acquired from the weather server 6 identified by the information source identification information IDS[2].

[0017] 5, the control mode storage unit 133 stores control mode information indicating a plurality of types of control modes for controlling the appliance 3 in association with air quality condition information indicating air quality conditions for the air quality inside and outside the building H in which the appliance 3 is installed, appliance information indicating the environment sensor 2 to be used and appliance identification information of the appliance 3, function classification information indicating a function classification when the control mode is classified based on the function realized by the appliance 3, and control mode identification information for identifying the control mode. Here, the function classification includes, for example, an "air quality improvement" function that prioritizes improving the air quality inside the building H, an "energy saving" function that prioritizes reducing the power consumption consumed by the appliance 3, an "automatic" function that maintains vacant rooms in the building H at a preset standard, and a "custom" function that is set by the user according to his / her preference. Here, the "energy saving" function is, in other words, a power consumption reduction function that prioritizes reducing the power consumption consumed by the appliance 3. In addition, the control mode of "control when the number of people increases" is a function that causes the appliance 3 to monitor the CO2 inside the building H. 2The "humidity exhaust control" control mode is a control mode for causing equipment 3 to perform a humidity reduction function that reduces the humidity inside building H. The "dust inflow prevention control" control mode is a control mode for causing equipment 3 to perform an outside air inflow reduction function that reduces the inflow of air from the outside of building H to the inside of building H. The "outside air intake control" control mode is a control mode for causing equipment 3 to perform a temperature difference reduction function that reduces the temperature difference between the temperature inside building H and the temperature outside building H.

[0018] In the example shown in FIG. 5, when the “air quality improvement” function C[0] or the “automatic” function C[2] is selected as the function classification, the CO 2 When the air quality condition of 500 ppm or more is met, the control mode indicated by the control mode information DCM[0], i.e., CO 2 This indicates that the device 3 is controlled based on the control mode of "control when the occupancy increases" which exhausts the condensed air outside the building H. In addition, when the "energy saving" function C[1] or the "automatic" function C[2] is selected as the functional classification, if the air quality conditions are met, that is, the temperature Ti inside the building H detected by the environmental sensor of the air conditioner 3A is 15°C or lower and the humidity Mi inside the building H is 65% or higher, the device 3 is controlled based on the control mode indicated by the control mode information DCM[3].

[0019] The function classification storage unit 134 stores the function classification information selected by the user in association with the user identification information of the user. The selected control mode storage unit 135 stores the control mode information, device identification information, and information source identification information selected by the control mode selection unit 117 in association with the user identification information of the corresponding user.

[0020] Returning to FIG. 3, when the driving state acquisition unit 111 acquires driving state information periodically transmitted from each device 3, the driving state acquisition unit 111 stores the acquired driving state information in the driving state storage unit 131 in association with device identification information that identifies the device 3 that is the transmission source of the driving state information. Here, the driving state acquisition unit 111 extracts, for example, a MAC address included in header information of a packet including the driving state information acquired from the device 3, and stores the extracted MAC address in association with the driving state information in the driving state storage unit 131. In addition, when the driving state acquisition unit 111 acquires driving state information from the device 3, the driving state acquisition unit 111 updates the driving state information stored in the driving state storage unit 131 based on the acquired driving state information. The driving state notification unit 112 transmits the driving state information stored in the driving state storage unit 131 to the terminal device 5 identified by the user identification information associated therewith.

[0021] The air quality acquisition unit 113 acquires air quality information of the building H in which the device 3 is installed. Specifically, the air quality acquisition unit 113 acquires air quality information indicating the air quality inside and outside the building H measured by an environmental sensor provided in the air conditioner 3A from the air conditioner 3A. The air quality acquisition unit 113 also acquires air quality information indicating the air quality measured by the environmental sensor 2 installed in the building H from the environmental sensor 2. Furthermore, the air quality acquisition unit 113 acquires air quality information indicating the air quality in the area in which the building H is located from the weather server 6. Here, the air quality acquisition unit 113 acquires outside-building air quality information from the weather server 6 by transmitting air quality information request information to the weather server 6 requesting the weather server 6 to transmit air quality information indicating the temperature, humidity, etc. of the area in which the building H is located.

[0022] When the functional classification acquisition unit 115 acquires the functional classification notification information described below transmitted from the terminal device 5, it extracts the functional classification information and user identification information contained in the acquired functional classification notification information, and stores the extracted information in the functional classification memory unit 134 in association with each other.

[0023] When new functional classification information is stored in the functional classification storage unit 134, the selectable controllable mode identification unit 116 identifies control mode identification information corresponding to the functional classification information from among the control mode identification information stored in the control mode storage unit 133. The selectable controllable mode identification unit 116 also refers to the device identification information stored in the operating state storage unit 131 and the information source identification information stored in the air quality storage unit 132, and identifies at least one of the environmental sensor 2, the device 3, and the weather server 6 that are linked to the cloud server 1 and can be used. Next, the selectable controllable mode identification unit 116 refers to the use device information corresponding to the identified control mode identification information stored in the control mode storage unit 133, and identifies, as the selectable controllable mode identification information, control mode identification information in which at least one of the environmental sensor 2, the device 3, and the weather server 6 indicated by the use device information can be used. Furthermore, the selectable controllable mode specifying unit 116 specifies control mode identification information in which at least one of the environmental sensor 2, the device 3, and the weather server 6 indicated by the device-in-use information corresponding to the specified control mode identification information is unavailable as unselectable control mode identification information. Then, the selectable controllable mode notifying unit 120 generates selectable controllable mode notification information including the specified selectable controllable mode identification information, unselectable control mode identification information, and unavailable device identification information and unavailable information source identification information indicating the unavailable environmental sensor 2, device 3, or weather server 6, and transmits it to the terminal device 5.

[0024] The control mode selection unit 117 refers to the device identification information stored in the operating state storage unit 131 and the information source identification information stored in the air quality storage unit 132 to identify at least one of the environmental sensor 2, the device 3, and the weather server 6 that are linked to the cloud server 1 and available. When new functional classification information is stored in the functional classification storage unit 134, the control mode selection unit 117 identifies control mode information corresponding to the newly stored functional classification information in the functional classification storage unit 134 from the control mode identification information stored in the control mode storage unit 133. Next, the control mode selection unit 117 selects at least one control mode from the identified control mode information based on the air quality information stored in the air quality storage unit 132. Here, when the control mode selection unit 117 determines that the air quality indicated by the air quality information stored in the air quality storage unit 132 satisfies the air quality condition indicated by the air quality condition information corresponding to the control mode information corresponding to the newly stored functional classification information in the functional classification storage unit 134, it selects the control mode information. Then, the control mode selection unit 117 updates the device identification information, information source identification information, and control mode information stored in the selected control mode memory unit 135 using the selected control mode information and the information included in the device identification information and information source identification information corresponding to the selected control mode information stored in the control mode memory unit 133 for at least one of the identified environmental sensors 2, devices 3, and weather server 6.

[0025] The device control unit 118 controls the device 3 in the control mode selected by the control mode selection unit 117. Specifically, the device control unit 118 generates control information for controlling the device 3 owned by the user identified by the corresponding user identification information, based on the control mode information, information source identification information, and device identification information stored in the selected control mode storage unit 135, and controls the operation of the device 3 by transmitting the generated control information to the device 3.

[0026] When control mode setting acquisition unit 119 acquires control mode setting information transmitted from terminal device 5, it updates the air quality condition information stored in control mode storage unit 133 based on the control mode identification information and air quality condition information included in the acquired control mode setting information. Alternatively, control mode setting acquisition unit 119 updates the function classification information stored in control mode storage unit 133 and corresponding to the control mode identification information based on the control mode identification information and function classification information included in the acquired control mode setting information.

[0027] Returning to FIG. 2, the terminal device 5 is, for example, a smartphone, and includes a CPU 501, a main memory unit 502, an auxiliary memory unit 503, a display unit 504, an input unit 505, a communication unit 506, and a bus 509 connecting these units to each other. The main memory unit 502 has a volatile memory such as a RAM, and is used as a working area for the CPU 501. The main memory unit 502 also has an image-only memory (not shown) that temporarily stores image information to be displayed on the display unit 504. The auxiliary memory unit 503 is a non-volatile memory such as a semiconductor flash memory, and stores programs for the CPU 501 to execute various processes. The display unit 504 is a display device such as a liquid crystal display or an organic EL (Electro-Luminescence) display. The input unit 505 is, for example, a transparent touch pad that is placed on top of the display unit 504. The communication unit 506 is connected to the wide area network NW1 and transmits information transferred from the CPU 501 to the cloud server 1 via the wide area network NW1, and transfers information received from the cloud server 1 via the wide area network NW1 to the CPU 501.

[0028] The CPU 501 reads out the program stored in the auxiliary storage unit 503 into the main storage unit 502 and executes it, thereby functioning as an operating state acquisition unit 511, a control mode acquisition unit 512, a display control unit 513, a reception unit 514, a function classification notification unit 515, a selected controllable mode acquisition unit 516, and a control mode setting notification unit 517, as shown in FIG. 3. The auxiliary storage unit 503 shown in FIG. 2 also has an operating state storage unit 531 and a control mode storage unit 532, as shown in FIG. 3. The operating state storage unit 531 stores operating state information indicating an operating state of at least one of the devices 3 installed in the building H, which is acquired from the cloud server 1, in association with the device identification information of the device 3. The control mode storage unit 532 stores control mode information for controlling the device 3.

[0029] When the driving state acquisition unit 511 acquires driving state information transmitted from the cloud server 1, it stores the acquired driving state information together with corresponding device identification information in the driving state storage unit 531. When the control mode acquisition unit 512 acquires control mode information transmitted from the cloud server 1, it stores the acquired control mode information in the control mode storage unit 532.

[0030] The reception unit 514 receives the operation content performed by the user on the input unit 505, generates operation information according to the received operation content, and notifies the display control unit 513, the function classification notification unit 515, or the control mode setting notification unit 517.

[0031] When the functional class notification unit 515 is notified of operation information indicating a functional class selection operation in which the user selects a functional class, the functional class notification unit 515 generates functional class notification information including functional class information indicating the functional class selected by the user and transmits the functional class notification information to the cloud server 1.

[0032] When the selectable controllable mode acquisition unit 516 acquires the selectable controllable mode notification information transmitted from the cloud server 1, it extracts the selectable controllable mode identification information, the non-selectable controllable mode information, the unusable device identification information, and the unusable information source identification information contained in the acquired selectable controllable mode notification information and notifies the display control unit 513.

[0033] The display control unit 513 forms one operation screen image to be displayed on the display unit 504, including the operating state information and the control mode information of the device 3, in order to provide a screen to be confirmed by the user when operating the device 3, and causes the display unit 504 to display the image. When the display control unit 513 is notified of operation information indicating a functional classification selection preparation operation for the user to select a functional classification, the display control unit 513 forms a functional classification selection image showing a list of functional classifications and causes the display unit 504 to display the image. When the display control unit 513 is notified of selectable controllable mode identification information and non-selectable controllable mode identification information from the selectable controllable mode acquisition unit 516, the display control unit 513 forms a control mode notification image based on the notified selectable controllable mode identification information and non-selectable controllable mode identification information, and causes the display unit 504 to display the image. When the display control unit 513 is notified of operation information indicating a functional classification selection operation for the user to select the classification of the "custom" function to change the contents of the "custom" function, the display control unit 513 forms an image for setting a control mode and causes the display unit 504 to display the image.

[0034] When control mode setting notification unit 517 is notified of operation information indicating a condition change operation by the user to change the air quality conditions in each control mode, it generates control mode setting information including the changed air quality condition information and control mode identification information that identifies the corresponding control mode, and transmits it to cloud server 1. Furthermore, when control mode setting notification unit 517 is notified of operation information indicating a setting change operation by the user to change the contents of the "custom" function, it generates control mode setting information including control mode identification information that identifies a control mode included in the classification of the "custom" function after the change, and function classification information that indicates the "custom" function, and transmits it to cloud server 1.

[0035] Next, the operation of the control system according to the present embodiment will be described with reference to Fig. 6 to Fig. 13. First, as shown in Fig. 6, when the information transmission time preset for the air conditioner 3A arrives, the air conditioner 3A generates operation state information indicating the operation state of the air conditioner 3A (step S1), and generates air quality information indicating the air quality inside the building measured by an environmental sensor provided in the air conditioner 3A (step S2). Next, the generated operation state information and air quality information are transmitted from the air conditioner 3A to the cloud server 1 (step S3). On the other hand, when the cloud server 1 acquires the operation state information and air quality information from the air conditioner 3A, it updates the operation state information stored in the operation state storage unit 131 and the air quality information stored in the air quality storage unit 132 with the acquired operation state information and air quality information (step S4). Furthermore, when the information transmission time preset for the ventilation device 3B arrives, the ventilation device 3B generates operation state information indicating the operation state of the ventilation device 3B (step S5). Next, the generated operating state information is transmitted from the ventilation device 3B to the cloud server 1 (step S6). On the other hand, upon acquiring the operating state information from the ventilation device 3B, the cloud server 1 updates the operating state information stored in the operating state storage unit 131 with the acquired operating state information (step S7).

[0036] Furthermore, when the information transmission time preset for the environmental sensor 2 arrives, the environmental sensor 2 generates air quality information indicating the measured air quality inside the building and the air quality outside the building (step S8). After that, the generated air quality information is transmitted from the environmental sensor 2 to the cloud server 1 (step S9). On the other hand, when the cloud server 1 acquires the air quality information from the environmental sensor 2, it updates the air quality information stored in the air quality storage unit 132 with the acquired air quality information (step S10). Next, when the preset time for acquiring air quality information from the weather server 6 arrives, the cloud server 1 transmits air quality information request information requesting the weather server 6 to transmit air quality information to the weather server 6 (step S11). On the other hand, when the weather server 6 acquires the air quality information request information, it generates air quality information indicating the air quality outside the building of the building H (step S12). Then, the generated air quality information is transmitted from the weather server 6 to the cloud server 1 (step S13). On the other hand, when the cloud server 1 acquires the air quality information from the weather server 6, it updates the air quality information stored in the air quality storage unit 132 with the acquired air quality information (step S14). Thereafter, the air conditioner 3A transmits operating state information and air quality information to the cloud server 1 each time the aforementioned information transmission time arrives, and the ventilator 3B transmits operating state information to the cloud server 1 each time the aforementioned information transmission time arrives. In addition, the environmental sensor 2 transmits air quality information to the cloud server 1 each time the aforementioned information transmission time arrives. In addition, the cloud server 1 acquires air quality information from the weather server 6 by transmitting air quality information request information to the weather server 6 each time the aforementioned air quality information acquisition time arrives.

[0037] 7, it is assumed that a preset control mode update time arrives and the cloud server 1 determines that the air quality indicated by the air quality information stored in the air quality storage unit 132 is satisfied (step S15). In this case, the cloud server 1 selects control mode information corresponding to the air quality conditions satisfied by the air quality indicated by the air quality information stored in the air quality storage unit 132, based on the air quality condition information corresponding to the functional classification selected by the user and stored in the control mode storage unit 133. The cloud server 1 also refers to the device identification information stored in the operating state storage unit 131 and the information source identification information stored in the air quality storage unit 132, and identifies at least one of the environmental sensor 2, the device 3, and the weather server 6 that are linked to the cloud server 1 and available. Then, the cloud server 1 updates the device identification information, information source identification information, and control mode information stored in the selected control mode storage unit 135 using the selected control mode information and the information included in the device identification information and information source identification information of at least one of the specified environmental sensor 2, device 3, and weather server 6 among the device identification information and information source identification information corresponding to the selected control mode information stored in the control mode storage unit 133 (step S16). Next, the cloud server 1 generates control information for controlling, for example, the ventilation device 3B owned by the user identified by the corresponding user identification information based on the control mode information, information source identification information, and device identification information stored in the selected control mode storage unit 135 (step S17). Then, the generated control information is transmitted from the cloud server 1 to the ventilation device 3B (step S18). On the other hand, when the ventilation device 3B acquires the control information from the cloud server 1, it starts operating according to the acquired control information (step S19).

[0038] Thereafter, the ventilation device 3B generates operating state information indicating its own operating state (step S20). Next, the generated operating state information is transmitted from the ventilation device 3B to the cloud server 1 (step S21). Meanwhile, upon acquiring the operating state information, the cloud server 1 updates the operating state information stored in the operating state storage unit 131 with the acquired operating state information (step S22). Next, the control mode information stored in the control mode storage unit 133 and the updated operating state information stored in the operating state storage unit 131 are transmitted from the cloud server 1 to the terminal device 5 (step S23).

[0039] On the other hand, when the terminal device 5 acquires the operating state information and the control mode information, the terminal device 5 forms an operation screen image based on the acquired operating state information and control mode information and displays it on the display unit 504 (step S24). Here, the terminal device 5 displays, for example, an operation screen image GA1 as shown in FIG. 8(A) on the display unit 504. The operation screen image GA1 includes a message image M121 indicating the type of control of the device 3, a message image M111 indicating the function classification selected by the user, and a message image M131 corresponding to the control mode. In addition, the operation screen image GA1 includes an icon image GA121 indicating the operating state of the device 3, and a button image BU11 indicating a touch position on the input unit 505 for switching the operation screen image GA1 to a function classification selection image for performing a function classification selection operation described later.

[0040] Returning to FIG. 7, when the user performs a function classification selection preparation operation for selecting a function classification, the terminal device 5 forms a function classification selection image showing a list of function classifications that the user can select, and displays it on the display unit 504 (step S25). Here, the terminal device 5 displays, for example, a function classification selection image GA2 as shown in FIG. 8(B) on the display unit 504. The function classification selection image GA2 includes message images M201, M202, M203, and M204 showing the function classifications, and icon images IC1, IC2, IC3, IC4, IC5, and IC6 showing the control modes adopted in each function classification. Here, the icon images IC1, IC2, IC3, IC4, IC5, and IC6 are displayed in different display modes depending on whether the corresponding control modes are executable or not. For example, among the control modes corresponding to the classification of the "automatic" function in FIG. 9, the control modes corresponding to the icon images IC1, IC3, and IC6 are executable, but the control modes corresponding to the icon images IC2, IC4, and IC5 are not executable. Also, among the control modes corresponding to the "energy saving" function classification, the control modes corresponding to icon images IC2 and IC5 are executable, but the control mode corresponding to icon image CI6 is not executable. Furthermore, among the control modes corresponding to the "air quality improvement" function classification, the control modes corresponding to icon images IC1 and IC3 are executable, but the control mode corresponding to icon image CI4 is not executable. Also, the function classification selection image GA2 includes button images BU201, BU202, BU203, and BU204 that are selected to switch the function classification selection image GA2 to a control mode notification image that notifies the contents of the control modes corresponding to each function classification.

[0041] Returning to FIG. 7, when the user performs a function classification selection operation to select a function classification, the terminal device 5 generates function classification notification information including function classification information indicating the function classification selected by the function classification selection operation (step S26), and the generated function classification notification information is transmitted from the terminal device 5 to the cloud server 1 (step S27). On the other hand, when the cloud server 1 acquires the function classification notification information, it extracts the function classification information and the user identification information included in the acquired function classification notification information, and stores the extracted information in the function classification storage unit 134 in association with each other (step S28). After that, as shown in FIG. 10, the cloud server 1 identifies the control mode identification information corresponding to the function classification information from the control mode identification information stored in the control mode storage unit 133. In addition, the cloud server 1 identifies at least one of the environmental sensor 2, the device 3, and the weather server 6 that are linked to the cloud server 1 and available, by referring to the device identification information stored in the operating state storage unit 131 and the information source identification information stored in the air quality storage unit 132. Then, the cloud server 1 refers to the device-used information corresponding to the identified control mode identification information stored in the control mode storage unit 133, and identifies the control mode identification information in which at least one of the environmental sensor 2, the device 3, and the weather server 6 indicated by the device-used information is available as the selectable controllable mode identification information. The cloud server 1 also identifies the control mode identification information in which at least one of the environmental sensor 2, the device 3, and the weather server 6 indicated by the device-used information corresponding to the identified control mode identification information is unavailable as the non-selectable controllable mode identification information (step S29). Next, the cloud server 1 generates selectable controllable mode notification information including the identified selectable controllable mode identification information and the non-selectable controllable mode identification information (step S30), and the generated selectable controllable mode notification information is transmitted from the cloud server 1 to the terminal device 5 (step S31). On the other hand, when the terminal device 5 acquires the selectable controllable mode notification information, it forms a control mode notification image based on the selectable controllable mode identification information and the non-selectable controllable mode identification information contained in the acquired selectable controllable mode notification information and displays it on the display unit 504 (step S32).

[0042] Here, the terminal device 5 displays, for example, a control mode notification image GA31 as shown in FIG. 11 on the display unit 504. The control mode notification image GA31 includes message images M301, M302, M303, M304, M305, and M306 representing the control modes, and icon images IC1, IC2, IC3, IC4, IC5, and IC6 representing the respective control modes. The control mode notification image GA31 also includes button images BU301, BU302, and BU303 selected when changing the air quality conditions for the control modes represented by "increase in number of people," "discharge of moisture," and "take in outside air." When the selectable control mode notification information includes non-selectable control mode identification information, the terminal device 5 displays, for example, a control mode notification image GA32 as shown in FIG. 12(A) on the display unit 504. In FIG. 12(A), the same components as those in the control mode notification image GA31 are denoted by the same reference numerals. The control mode notification image GA32 includes an icon image IC32 indicating that the control mode cannot be selected. When a portion of the input unit 505, which is a touch pad, that corresponds to the icon image IC32 is touched, the terminal device 5 forms a guide image GA33 including a message image M321 indicating a message including the name of the device 3 identified by the unavailable device identification information or the device 3 identified by the unavailable information source identification information, the environmental sensor 2, etc., as shown in FIG. 12(B), based on the unavailable device identification information or the unavailable information source identification information, and a button image BU331 selected when switching to the control mode notification image GA32, and displays the guide image GA33 on the display unit 504.

[0043] 10, it is next assumed that the cloud server 1 determines that the air quality indicated by the air quality information stored in the air quality storage unit 132 is satisfied (step S33). In this case, the cloud server 1 selects control mode information corresponding to the air quality conditions satisfied by the air quality indicated by the air quality information stored in the air quality storage unit 132, based on the air quality condition information corresponding to the functional classification selected by the user, stored in the control mode storage unit 133. Furthermore, the cloud server 1 refers to the device identification information stored in the operating state storage unit 131 and the information source identification information stored in the air quality storage unit 132, and identifies at least one of the environmental sensor 2, the device 3, and the weather server 6 that are linked to the cloud server 1 and available. Then, the cloud server 1 updates the device identification information, information source identification information, and control mode information stored in the selected control mode storage unit 135 using the selected control mode information and the information included in the device identification information and information source identification information of at least one of the specified environmental sensors 2, devices 3, and weather server 6 among the device identification information and information source identification information corresponding to the selected control mode information stored in the control mode storage unit 133 (step S34). After that, the cloud server 1 generates control information for controlling, for example, the air conditioner 3A and the ventilation device 3B owned by the user identified by the corresponding user identification information based on the control mode information, information source identification information, and device identification information stored in the selected control mode storage unit 135 (step S35), and the generated control information is transmitted from the cloud server 1 to the air conditioner 3A and the ventilation device 3B, respectively (steps S36 and S37).

[0044] On the other hand, when the air conditioner 3A acquires the control information from the cloud server 1, it starts operating according to the acquired control information (step S38). Next, the air conditioner 3A generates operating state information indicating the operating state of the own device (step S39). Next, the generated operating state information is transmitted from the air conditioner 3A to the cloud server 1 (step S40). On the other hand, when the cloud server 1 acquires the operating state information, it updates the operating state information stored in the operating state storage unit 131 with the acquired operating state information (step S41). Also, when the ventilation device 3B acquires the control information from the cloud server 1, it starts operating according to the acquired control information (step S42). Thereafter, the ventilation device 3B generates operating state information indicating the operating state of the own device (step S43). Next, the generated operating state information is transmitted from the ventilation device 3B to the cloud server 1 (step S44). On the other hand, when the cloud server 1 acquires the operating state information, it updates the operating state information stored in the operating state storage unit 131 with the acquired operating state information (step S45). Next, the control mode information stored in the control mode storage unit 133 and the updated operating state information stored in the operating state storage unit 131 are transmitted from the cloud server 1 to the terminal device 5 (step S46). Then, as shown in Fig. 13, when the user performs an operation screen image switching operation on the input unit 505 of the terminal device 5 to switch the control mode notification image to an operation screen image, the terminal device 5 forms an operation screen image based on the operating state information and control mode information transmitted from the cloud server 1 and displays it on the display unit 504 (step S47).

[0045] Also, when the user performs a function classification selection operation to select the classification of the "custom" function, the terminal device 5 forms a control mode setting image and displays it on the display unit 504 (step S48). Here, the terminal device 5 displays, for example, a control mode setting image GA4 as shown in FIG. 14 on the display unit 504. In FIG. 14, the same components as the control mode notification image GA31 are given the same reference numerals as in FIG. 11. The control mode setting image GA4 includes button images BU401, BU402, BU403, BU404, BU405, and BU406 for setting whether or not to select each control mode. In the example shown in FIG. 14, only the control mode for "defrosting" is selected, and other control modes are not selected. Here, as shown in FIG. 13, it is assumed that the user performs a setting change operation to change the control mode to be selected for the "custom" function. In this case, the terminal device 5 generates control mode setting information including the control mode identification information of the changed control mode, the function classification information of the "custom" function, and the user identification information (step S49). Then, the generated control mode setting information is transmitted from the terminal device 5 to the cloud server 1 (step S50). On the other hand, upon acquiring the control mode setting information, the cloud server 1 extracts the control mode identification information, the function classification information, and the user identification information included in the acquired control mode setting information, and updates the function classification information of the "custom" function and the corresponding control mode identification information corresponding to the extracted user identification information, which are stored in the control mode storage unit 133, using the extracted information (step S51).

[0046] Thereafter, the terminal device 5 generates function classification notification information including the function classification information of the “custom” function and the user identification information (step S52), and the generated function classification notification information is transmitted from the terminal device 5 to the cloud server 1 (step S27). Next, a series of processes from step S28 onwards are executed.

[0047] Next, the device control process for controlling the device 3 executed by the cloud server 1 according to the present embodiment will be described with reference to FIG. 15. The device control process is started when a program for executing the device control process is started in the cloud server 1. First, the driving state acquisition unit 111 and the air quality acquisition unit 113 determine whether or not they have acquired driving state information and air quality information (step S101). If the driving state acquisition unit 111 and the air quality acquisition unit 113 determine that they have not acquired driving state information and air quality information (step S101: No), the process of step S103 described below is executed. On the other hand, if at least one of the driving state acquisition unit 111 and the air quality acquisition unit 113 determines that they have acquired driving state information and air quality information (step S101: Yes), the driving state information and air quality information stored in the driving state storage unit 131 and the air quality storage unit 132 are updated with the acquired driving state information and air quality information (step S102).

[0048] Next, the control mode selection unit 117 judges whether or not the control mode update time has arrived (step S103). If the control mode selection unit 117 judges that the control mode update time has not yet arrived (step S103: No), the process of step S110 described later is executed. On the other hand, it is assumed that the control mode selection unit 117 judges that the control mode update time has arrived (step S103: Yes). In this case, the control mode selection unit 117 refers to the air quality condition information stored in the control mode storage unit 133 and corresponding to the function classification information selected by the user, and judges whether or not the air quality inside and outside the building H indicated by the air quality information stored in the air quality storage unit 132 satisfies the air quality condition indicated by the referenced air quality condition information (step S104). If the control mode selection unit 117 judges that the air quality inside and outside the building H does not satisfy the above-mentioned air quality condition (step S104: No), the process of step S109 described later is executed.

[0049] On the other hand, when the control mode selection unit 117 determines that the air quality inside and outside the building H satisfies the air quality condition (step S104: Yes), it selects the control mode information corresponding to the air quality condition from the control mode information stored in the control mode storage unit 133 and corresponding to the function classification information selected by the user (step S105). Next, the device control unit 118 generates control information based on the selected control mode information and transmits it to the device 3 (step S106). After that, when the operating state acquisition unit 111 acquires the operating state information transmitted from the device 3 (step S107), it updates the operating state information stored in the operating state storage unit 131 with the acquired operating state information (step S108). Next, the operating state notification unit 112 transmits the updated operating state information stored in the operating state storage unit 131 to the terminal device 5, and the control mode notification unit 114 transmits the selected control mode information to the terminal device 5 (step S109).

[0050] Next, the function classification acquisition unit 115 judges whether or not the above-mentioned function classification notification information transmitted from the terminal device 5 has been acquired (step S110). Here, when the function classification acquisition unit 115 judges that the function classification notification information has been acquired (step S110: Yes), it extracts the function classification information and the user identification information included in the acquired function classification notification information, and stores the extracted information in the function classification storage unit 134 in association with each other (step S111). After that, when new function classification information is stored in the function classification storage unit 134, the selectable controllable mode specification unit 116 specifies the control mode identification information corresponding to the function classification information from the control mode identification information stored in the control mode storage unit 133. In addition, the selectable controllable mode specification unit 116 specifies at least one of the environmental sensor 2, the device 3, and the weather server 6 that are linked to the cloud server 1 and available, by referring to the device identification information stored in the operating state storage unit 131 and the information source identification information stored in the air quality storage unit 132. Next, the selectable controllable mode identification unit 116 refers to the use device information corresponding to the identified control mode identification information stored in the control mode storage unit 133, and identifies control mode identification information in which at least one of the environmental sensor 2, the device 3, and the weather server 6 indicated by the use device information corresponding to the identified control mode identification information is usable as selectable controllable mode identification information. Also, the selectable controllable mode identification unit 116 identifies control mode identification information in which at least one of the environmental sensor 2, the device 3, and the weather server 6 indicated by the use device information corresponding to the identified control mode identification information is unusable as unselectable controllable mode identification information (step S112). Next, the selectable controllable mode notification unit 120 generates selectable controllable mode notification information including the identified selectable controllable mode identification information, unselectable controllable mode identification information, unusable device identification information, and unusable information source information, and transmits it to the terminal device 5 (step S113). Then, the process of step S104 is executed again.

[0051] Also, when the function classification acquisition unit 115 determines in step S110 that the function classification notification information has not been acquired (step S110: No), the control mode setting acquisition unit 119 determines whether or not the control mode setting information transmitted from the terminal device 5 has been acquired (step S114). Here, when the control mode setting acquisition unit 119 determines that the control mode setting information has not been acquired (step S114: No), the process of step S101 is executed again. On the other hand, when the control mode setting acquisition unit 119 determines that the control mode setting information has been acquired (step S114: Yes), the control mode setting acquisition unit 119 updates the air quality condition information stored in the control mode storage unit 133 based on the control mode identification information and function classification information or the control mode identification information and air quality condition information included in the acquired control mode setting information (step S115). After that, the process of step S110 is executed again.

[0052] As described above, according to the control system of the present embodiment, the control mode selection unit 117 selects one control mode based on the air quality information from at least one control mode associated with function classification information indicating a function classification selected by the user and stored in the control mode storage unit 133. Then, the device control unit 118 controls the device 3 in the one control mode selected by the control mode selection unit. As a result, the device 3 is controlled in one control mode belonging to the functional classification of functions desired to be realized for the multiple devices 3 selected by the user, so that the device 3 can exhibit functions suited to the user's life scene.

[0053] Further, according to the control system of the present embodiment, the selectable controllable mode specifying unit 116 of the cloud server 1 specifies the device 3 linked to the cloud server 1, and specifies as a selectable controllable mode, among the control modes stored in the control mode storage unit 133, a control mode in which all corresponding device identification information is included in the device identification information of each of the specified devices 3, and specifies as a non-selectable controllable mode, among the control modes stored in the control mode storage unit 133, a control mode in which any of the corresponding device identification information is different from any of the device identification information of each of the specified devices 3. Then, the display control unit 513 of the terminal device 5 forms an operation screen image or a function classification selection image such that the icon images IC1, IC2, IC3, IC4, IC5, and IC6 have different display modes when the corresponding control mode is a selectable controllable mode and when the corresponding control mode is a non-selectable controllable mode. This allows the user to easily grasp the selectable control modes simply by checking the display modes of the icon images IC1, IC2, IC3, IC4, IC5, and IC6 included in the operation screen image or function classification selection image displayed on the display unit 504 of the terminal device 5.

[0054] Furthermore, when a non-selectable control mode is included in the control modes corresponding to the function classification selected by the user, the display control unit 513 of the terminal device 5 forms a control mode notification image including an icon image IC32 indicating that the control mode is a non-selectable control mode. This allows the user to easily grasp the selectable control modes simply by checking the presence or absence of the icon image IC32 with the control mode notification image displayed on the display unit 504 of the terminal device 5.

[0055] Although the embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-mentioned embodiment. For example, the device control unit 118 of the cloud server 1 may control the device 3 in one control mode selected from at least one control mode associated with the function classification information indicating the air quality improvement function, so that the amount of air flowing from the outside of the building H to the inside of the building H is equal to or greater than the first reference flow rate set in advance. For example, when the device control unit 118 selects a control mode corresponding to the control mode information of "control when the number of people increases" and "humidity discharge control" corresponding to the function classification information C[0] of the "air quality improvement" function stored in the control mode storage unit 133, the device control unit 118 may control the ventilation device 3B so that the amount of air flowing from the outside of the building H to the inside of the building H by the ventilation device 3B is equal to or greater than the first reference flow rate set in advance. Alternatively, the device control unit 118 of the cloud server 1 may control the device 3 in one control mode selected from at least one control mode associated with the function classification information indicating the power consumption reduction function, so that the amount of air flowing from the outside of the building H to the inside of the building H is equal to or greater than the first reference flow rate set in advance. For example, when the device control unit 118 selects a control mode corresponding to the control mode information of "outside air intake" corresponding to the function classification information C[1] of the "energy saving" function stored in the control mode storage unit 133, the device control unit 118 may control the ventilation device 3B so that the amount of air flowing from the outside of the building H to the inside of the building H by the ventilation device 3B is equal to or greater than the first reference flow rate. For example, when the temperature outside the building H is lower than the temperature inside the building H, such as in the evening hours of summer, the amount of air flowing from the outside of the building H to the inside of the building H by the ventilation device 3B is increased to actively take in outside air into the building H, thereby reducing power consumption compared to the case of lowering the temperature inside the building H using the air conditioner 3A.

[0056] According to this configuration, by increasing the amount of air flowing from the outside of building H to the inside of building H, ventilation inside building H is promoted, thereby improving the air quality inside building H.

[0057] In the embodiment, the device control unit 118 of the cloud server 1 may control the device 3 in one control mode selected from at least one control mode associated with function classification information indicating a power consumption reduction function, so that the amount of air flowing in from the outside of the building H to the inside of the building H is equal to or less than a preset second reference flow rate that is smaller than the first reference flow rate. For example, when the device control unit 118 selects a control mode corresponding to the control mode information of "defrosting" that corresponds to the function classification information C[1] of the "energy saving" function stored in the control mode storage unit 133, the device control unit 118 may control the ventilation device 3B so that the amount of air flowing in from the outside of the building H to the inside of the building H by the ventilation device 3B is equal to or less than the second reference flow rate.

[0058] According to this configuration, by reducing the amount of air flowing in from the outside of building H to the inside of building H, changes in the temperature, humidity, etc. of the air inside building H can be suppressed. Therefore, for example, the load on the air conditioner 3A installed in building H to heat or cool the air is reduced, and power consumption by the air conditioner 3A can be reduced.

[0059] In the embodiment, the ventilation device 3B may be a ventilation device with an inside / outside building heat exchange function that exchanges heat between the air outside the building H and the air inside the building H. At least one control mode associated with the function classification information indicating the temperature difference reduction function may be a control mode that controls the ventilation device 3B with the inside / outside building heat exchange function.

[0060] According to this configuration, heat exchange can be performed between the air outside the building H and the air inside the building H, which helps to reduce the temperature difference between the air outside the building H and the air inside the building H. Therefore, for example, the load on the air conditioner 3A installed in the building H when heating or cooling the air inside the building H to reduce the temperature difference between the air inside the building H and the air outside the building H is reduced, and the power consumption of the air conditioner 3A can be reduced.

[0061] In addition, the various functions of the cloud server 1 and terminal device 5 according to the present disclosure can be realized by using a normal computer system, not by a dedicated system. For example, a program for executing the above operations may be stored in a non-transitory recording medium (such as a CD-ROM (Compact Disc Read Only Memory)) that can be read by a computer system and distributed to a computer connected to a network, and the cloud server 1 and terminal device 5 that execute the above processes may be configured by installing the program in the computer system.

[0062] The method of providing the program to the computer is arbitrary. For example, the program may be uploaded to a bulletin board (BBS (Bulletin Board System)) on a communication line and distributed to the computer via the communication line. The computer then starts up the program and executes it under the control of an OS (Operating System) in the same way as other applications. In this way, the computer functions as a cloud server 1 or a terminal device 5 that executes the above-mentioned processes.

[0063] Although the embodiments and modifications of the present disclosure have been described above, the present disclosure is not limited to these. The present disclosure includes appropriate combinations of the embodiments and modifications, and appropriate modifications thereto.
