It is characterized by providing.

  The program of this invention is for making a computer function as a ventilation assistance apparatus.

  According to the configuration of the present invention, the recommended information for managing the indoor air quality is output according to the environmental information related to the outdoor air quality of the building, so that the support for maintaining the indoor air in a clean state is provided. Has the advantage of becoming possible.

It is a figure which shows the example of a display of the recommendation information in embodiment. It is a block diagram which shows the other modification of embodiment. It is a block diagram which shows the further another modification of embodiment.

  Embodiment described below assumes the structural example which implement | achieves a ventilation assistance apparatus with a smart phone. However, the ventilation support device may be realized by a tablet terminal, and if it is not necessary to carry the ventilation support device, the ventilation support device may be realized by a personal computer. You may use the apparatus selected from a smart phone, a tablet terminal, a personal computer etc. as a presentation apparatus provided with the display. In this case, many functions of the ventilation support device to be described later are realized by a HEMS (Home Energy Management System) controller, a home information board integrated with a home intercom, or a server that communicates through an electric communication line such as the Internet. May be.

  The buildings described below are basically assumed to be houses. The house may be a detached house or an apartment house. In the case of an apartment house, the building means an individual dwelling unit that is a part of the building, not the entire building in which a plurality of dwelling units are assembled. Furthermore, the building may be a tenant in an office building or a commercial building. Alternatively, the building may be read as a room.

  It is desirable that the controller of the HEMS arranged in the house has a function of communicating with at least a part of equipment used in the house and instructing the equipment to operate. As will be described later, a controller having this type of function can be used as an instruction unit for instructing the equipment to operate.

  The server preferably has a configuration using a plurality of computers rather than a configuration using a single computer. In addition, a server configured using a plurality of computers is not limited to a configuration that is concentrated in one place, and may be configured as a cloud computing system.

  In the configuration example shown in FIG. 1, a building 30 is a house, and as a facility 20 that changes indoor air quality, a mechanical ventilation device 21 and a natural ventilation device 22 are provided as the facility 20. The configuration will be described as an example. However, the building 30 may include only one of the ventilation device 21 and the ventilation device 22 as the facility 20.

  The ventilator 21 may be either a ventilator that exhausts air from the indoor 31 to the outdoor 32 or a ventilator that exhausts air from the outdoor 32 to the indoor 31, or a combination of both. That is, the ventilator may be configured to perform any of the first type ventilation, the second type ventilation, and the third type ventilation. However, in the present embodiment, it is assumed that the ventilation device 21 exhausts air from the indoor 31 to the outdoor 32. Therefore, the ventilator 21 may be a range hood arranged in a kitchen, in addition to a ventilation fan arranged in a living room.

  The ventilation device 21 has a configuration in which a user (resident) using the building 30 manually performs operation and stop instructions, and also performs operation and stop operations according to instructions from an external device such as a HEMS controller. There may be.

  The ventilation device 22 basically assumes a window, but may have a configuration other than the window as long as air is circulated between the indoor 31 and the outdoor 32. For example, the ventilation device 22 may be configured to be disposed in an opening such as a window or to penetrate a wall. The ventilation device 22 can be selected between an open state that permits air flow between the indoor 31 and the outdoor 32 and a closed state that blocks air flow.

  If the ventilation device 22 is a window, the open state and the closed state correspond to the open state and the closed state of the window. Further, in the ventilation device 22 other than the window, the open state and the closed state are realized by an opening / closing device such as a damper or a valve. In addition to the normal configuration in which the user (resident) who uses the building 30 manually selects the open state and the closed state, the ventilator 22 opens and closes in accordance with instructions from an external device such as a HEMS controller. The configuration may be such that and are performed electrically.

  This embodiment demonstrates using the example which a user operates the switch attached to the ventilation apparatus 21 like a ventilation fan or a range hood, or the user directly operates the ventilation apparatus 22 like a window manually. In other words, the configuration in which the user performs an operation on the facility 20 instead of the configuration in which the facility 20 is automatically controlled will be described as an example. That is, the ventilation support device 10 has a function of notifying the user of the operation of the facility 20, but does not have a function of changing the operation of the facility 20.

  As the recommended information, the ventilation support device 10 of the present embodiment stops the operation of the ventilation device 21 and closes the ventilation device 22 when the air quality of the outdoor 32 of the building 30 does not satisfy the criterion. , Configured to notify the user. Therefore, the ventilation support apparatus 10 acquires information on the air quality of the outdoor 32 of the building 30. Here, the air quality means the concentration of particulate matter, dust, yellow sand, pollen, sulfur oxide, nitrogen oxide and the like. The particulate matter means PM2.5 (PM: Particulate Matter), PM10, or the like.

  In the following example, AQI information (AQI: Air Quality Index) known as an air quality index or an air quality index is used as air quality information. That is, the criterion is set for AQI. For example, when the AQI exceeds a threshold that is a predetermined criterion, the user is notified as recommended information that the operation of the ventilator 21 is stopped and the ventilator 22 is closed. The relationship between AQI information and recommended information will be described later.

  In this embodiment, since the ventilation assistance apparatus 10 assumes the smart phone, the communication part 11 acquires the information on the air quality of the outdoors 32 through an electric communication line. The communication unit 11 performs wireless communication using radio waves as a transmission medium. The telecommunication line is the Internet or a mobile telephone network.

  In order for the ventilation support apparatus 10 to acquire air quality information through the telecommunication line, the ventilation support apparatus 10 needs to specify the location of the building 30. The location of the building 30 may be registered in advance in the ventilation support device 10 by the user of the ventilation support device 10. In this case, the air quality information is obtained for an area including a place registered in the ventilation support device 10.

  Moreover, in this embodiment, since the smart phone is assumed as the ventilation assistance apparatus 10, the current position of the ventilation assistance apparatus 10 is detected by the position detection unit 12 such as GPS (Global Positioning System) provided in the ventilation assistance apparatus 10. It is desirable to obtain position information. In this configuration, when the current position obtained by the position detection unit 12 is in the vicinity of the registered position of the building 30, the ventilation support apparatus 10 acquires air quality information regarding the corresponding place. In this configuration, when the user carries the ventilation support device 10, the air quality information of the outdoor 32 is not acquired and unnecessary communication traffic does not occur unless the user approaches the building 30. As described above, when the position information of the current position is registered in the ventilation support device 10 and the ventilation support device 10 is used in the corresponding building 30, the position detection unit 12 is not essential.

  In order to acquire air quality information on the outdoor 32 of the building 30, it is possible to install a sensor for measuring the air quality on the outdoor 32. In this case, the ventilation assistance apparatus 10 should just acquire the information of the air quality which the sensor acquired directly or indirectly. When the ventilation support device 10 directly acquires air quality information from the sensor, wireless communication with the sensor is performed through the communication unit 11 of the ventilation support device 10. In addition, when the ventilation support device 10 indirectly acquires air quality information from the sensor, for example, the sensor communicates with the controller of the HEMS, and the ventilation support device 10 transmits the air quality of the outdoor 32 through this controller. Get information.

  The ventilation support apparatus 10 includes a processing unit 13 that obtains environmental information that classifies the air quality using the air quality information in the outdoor 32 of the building 30. In this embodiment, since AQI information is used as air quality information, the environment information uses information obtained by dividing the AQI value into stages. For example, the environmental information is set as “good” when the AQI is from 1 to 100, “attention” when the AQI is from 101 to 150, “bad” when the AQI is 151 or more, and the like. Here, the environmental information is divided into three stages, but the number of stages is not particularly limited, and may be divided into, for example, five stages.

  Now, if the facility 20 is a window that is a ventilation device 22, “good” indicates that the window may be opened, and “caution” can open the window, but it is susceptible to air quality. In some cases, it is recommended to keep the window closed. “Bad” represents a level at which the air quality has deteriorated to such an extent that the window is closed. Table 1 shows an example of setting environment information in this case. Information as shown in Table 1 is stored in the storage unit 14 provided in the ventilation support device 10.

  For example, it is assumed that air quality information (AQI information) is obtained every hour in the day, and the air quality information changes as shown in FIG. In FIG. 2, one bar represents AQI in one hour. For example, the AQI at 0:00 represents the AQI from 0:00, that is, from 0:00 to 0:59.

  In the illustrated example, since the AQI is 85 at 7:00, the processing unit 13 refers to the storage unit 14 to obtain environmental information of the category “good” and generates recommended information indicating that the window can be opened. To do. In addition, since the AQI is 133 at 13:00, the processing unit 13 requests environmental information of “caution” and can open the window, but if it is susceptible to air quality (if it is sensitive), the window The recommendation information that it is recommended to close is generated. Furthermore, since the AQI is 194 at 15:00, the processing unit 13 refers to the storage unit 14 to obtain environmental information “bad” and generates recommended information indicating that the window is closed.

  As in the example described above, when the processing unit 13 acquires air quality information, the processing unit 13 obtains a classification of the environmental information, and generates recommended information corresponding to the classification of the environmental information. The recommended information generated by the processing unit 13 is output to the presentation device 16 through the output unit 15 included in the ventilation support device 10. In this embodiment, since the ventilation assistance apparatus 10 is a smart phone, the presentation apparatus 16 is provided in the housing | casing 101 of the ventilation assistance apparatus 10. FIG. The presentation device 16 includes a display 161 composed of a flat panel display such as a liquid crystal display, and a touch panel 162 is superimposed on the screen of the display 161.

  The output unit 15 displays the recommended information on the screen of the display 161 in a format such as the display example of FIG. In the example shown in FIG. 3, the screen of the display 161 shows that the AQI has reached 194 at 15:00, and the recommended information including the message “Please close the window” is displayed on the screen of the display 161. It is shown. Such a display example is an example, and the output unit 15 may be configured to display only recommended information on the screen of the display 161.

  That is, the processing unit 13 generates recommended information for managing the indoor air quality of the building 30 according to the environment information, and the output unit 15 outputs the recommended information generated by the processing unit 13 to the display 161. A format for displaying the recommended information on the display 161 is determined by the output unit 15. Note that the presentation device 16 is not limited to the configuration in which the recommended information is visually presented to the user through the display device 161, and may be configured to present the recommended information to the user by audio.

  In addition, since the recommended information is often unnecessary during a time zone such as sleeping or going out, the ventilation support device 10 can register a time zone in which the recommended information is presented or a time zone in which the recommended information is not presented. It is desirable to include a registration unit 18. If a time zone in which recommended information is presented or a time zone in which recommended information is not presented is registered in the time zone registration unit 18, presentation or non-presentation of recommended information is selected in the corresponding time zone.

  In the operation example described above, a case where the processing unit 13 generates recommended information indicating an operation recommended for the window as the ventilation device 22 in the equipment 20 is shown. However, the recommended information is recommended for the equipment 20. Any operation is acceptable. For example, the recommended information may be an operation recommended for the ventilation device 21.

  By the way, the processing unit 13 generates recommended information when the air quality satisfies a predetermined determination criterion. When the processing unit 13 generates the recommended information, the output unit 15 displays the recommended information on the screen of the display 161. The timing for generating and presenting recommended information is set so as to be displayed. In this operation, for example, when the environmental information becomes “bad”, recommended information is presented to the user to close the window, and then the user performs an operation of closing the window. That is, the user operates the facility 20 with a slight delay from the time when the air quality deteriorates.

  For such an operation, the processing unit 13 may predict the timing at which the air quality meets the determination criterion based on the tendency of the air quality to change with time. In this case, the output unit 15 can display the recommended information on the screen of the display 161 before the timing at which the air quality is predicted to satisfy the determination criterion. The output unit 15 desirably displays the recommended information on the screen of the display 161 a predetermined time (for example, 1 minute, 5 minutes, 10 minutes, etc.) before the timing predicted by the processing unit 13.

  If such an operation is performed, the user can easily maintain the air quality of the indoor 31 in an appropriate state by operating the facility 20 before the air quality satisfies the determination standard. The operation for displaying the recommended information on the display 161 before the air quality satisfies the determination criterion may be performed only when the air quality deteriorates. That is, when air quality deteriorates, it is desirable to prevent deterioration of the air quality of the indoor 31 by operating the facility 20 in advance.

  In the configuration example described above, the ventilation support device 10 includes the communication unit 11, the position detection unit 12, the processing unit 13, the storage unit 14, and the output unit 15, and further, the presentation device 16 is provided in the casing 101 of the ventilation support device 10. Is provided. In other words, the ventilation support apparatus 10 is realized by causing a smartphone to execute an application program. The device that can function as the ventilation support device 10 is not limited to a smartphone, and may be a tablet terminal, a personal computer, or the like. In short, the ventilation support apparatus 10 is realized by executing a program by a computer having a main hardware element such as a device including a processor that operates according to the program and a device that constitutes an interface unit with the presentation apparatus 16.

  The program is provided in a state written in a ROM (Read Only Memory), or is provided through an electric communication line such as the Internet. Further, the program may be provided in a state where the program is written in a computer-readable recording medium. When the ventilation support apparatus 10 is selected from a smartphone, a tablet terminal, a personal computer, or the like, the program is preferably provided as an application program (so-called application).

  By the way, in the configuration example described above, the recommended information is only displayed on the screen of the display 161, and the user actually performs the operation of operating the equipment 20 according to the recommended information displayed on the display 161. Assumed. On the other hand, the facility 20 may be configured to receive a radio signal using radio waves or light as a transmission medium and to be operable with the contents instructed by the radio signal. If the ventilation support apparatus 10 can give an instruction to such equipment 20, the user can operate the equipment 20 by operating the ventilation support apparatus 10 without manually operating the individual equipment 20. become.

  FIG. 4 shows an example in which the ventilation support apparatus 10 includes the instruction unit 17 and the instruction unit 17 can give an instruction regarding the operation to the equipment 20. In this configuration, as shown in FIG. 5, a graphic regarding the operation of the facility 20 is displayed on the screen of the display 161. For example, if the facility 20 includes a window as a ventilator 22 and a ventilator 21, the figure of the buttons B1 and B2 for operating the ventilator 21 to operate and stop as in the illustrated example. And the graphic of the window W1 are displayed on the screen of the display 161.

  In the illustrated example, when an operation input is given to the figure of the window W1 from the touch panel 162, an instruction is given to the window as the facility 20 from the instruction unit 17, and the window is opened or closed according to the operation input. It is possible to operate. Further, since the buttons B1 and B2 corresponding to the ventilation device 21 are indicated by a figure simulating a push button switch, when an operation input is given from the touch panel 162 at a portion corresponding to the buttons B1 and B2, the ventilation device 21 is transmitted from the instruction unit 17. Is given instructions for driving or stopping.

  The processing unit 13 performs an operation input to a part corresponding to the graphic on the touch panel 162 during a period in which the output unit 15 displays the graphic such as the window W1 or the buttons B1 and B2 and the recommended information on the screen of the display 161. Is given to the facility 20 through the instruction unit 17. Therefore, the ventilation support device 10 can be used as a remote control device (commander) for the facility 20 and the operation corresponding to the recommended information can be performed from the ventilation support device 10.

  Here, if an instruction is given from the ventilation support device 10 to the facility 20, a registration work for connecting the ventilation support device 10 to each facility 20 is required, which may impair convenience. When the HEMS controller is arranged in the building 30 and the controller communicates with the facility 20 to manage the facility 20, the ventilation support device 10 communicates with the controller, thereby the facility 20 via the controller. An instruction may be given to. When this configuration is adopted, since the facility 20 has already been registered in the controller, the ventilation support device 10 has only to perform the registration work for only the controller, so the registration work becomes easy.

  In the configuration example described above, the recommended information is displayed on the screen of the display 161, and the user gives an instruction to the equipment 20 from the ventilation support device 10 according to the content of the recommended information. You may automate according to. That is, when the processing unit 13 generates recommended information, an instruction may be given to the facility 20 through the instruction unit 17 according to the content of the recommended information.

  In the configuration example described above, the ventilation support device 10 acquires information on the air quality of the outdoor 32 and, according to the acquired air quality, recommend information including operation details for the facility 20 that manages the air quality of the indoor 31. Output. However, the configuration example described above is an example, and other configurations can be employed.

  For example, as illustrated in FIG. 6, a mobile terminal 41 such as a smartphone is used as the position detection unit 12 and the presentation device 16, and the communication unit 11, the processing unit 13, the storage unit 14, and the output unit 15 are realized by the server 42. May be. The mobile terminal 41 and the server 42 communicate through an electric communication line 40 such as the Internet or a mobile telephone network. That is, the server 42 receives position information from the mobile terminal 41, obtains air quality at a location corresponding to the position information, generates recommended information, and transmits the recommended information to the mobile terminal 41. It may be. The mobile terminal 41 displays the recommended information from the server 42 on the display 161. Moreover, if the instruction | indication part 17 is required, the instruction | indication part 17 may be implement | achieved in the mobile terminal 41, and what is necessary is just to give an instruction | indication from the mobile terminal 41 to the equipment 20 or the controller of HEMS.

  As shown in FIG. 7, the communication unit 11, the processing unit 13, the storage unit 14, and the output unit 15 may be realized by a HEMS controller 43 instead of the server 42. In this configuration, it is desirable to control the facility 20 via the controller 43 by giving an instruction regarding the control content of the facility 20 from the instruction unit 17 to the controller 43.

  The ventilation support device 10 described in the present embodiment provides the processing unit 13 that obtains environmental information that classifies the air quality of the outdoor 32 of the building 30 and the recommended information for managing the air quality of the indoor 31 of the building 30 as environmental information. And an output unit 15 for outputting in response to the above.

  According to this configuration, it is possible to provide recommended information for managing the air quality according to the air quality of the outdoors 32. Therefore, it is possible to reduce the possibility of taking the air of the outdoor 32 into the indoor 31 when the air quality of the outdoor 32 is deteriorated. That is, it is possible to reduce the possibility that a user in the room 31 sucks air with a deteriorated air quality. In addition, if the air quality of the outdoor 32 is reduced, the air of the outdoor 32 is not taken into the indoor 31, and ventilation is possible if the air quality of the outdoor 32 is clean. It can be maintained in a good state. Therefore, when an air purifier is provided in the indoor 31, it is possible to maintain the air quality of the air taken in by the air purifier in a relatively clean state, and as a result, filter replacement of the air purifier, etc. The maintenance frequency can be reduced.

  Moreover, it is preferable that the ventilation assistance apparatus 10 is provided with the communication part 11 which acquires the information regarding the outdoor air quality in a present position by communication. In this case, it is desirable that the processing unit 13 obtains environmental information based on information related to the air quality of the outdoor 32, and the output unit 15 outputs the recommended information to the presentation device 16.

  In this configuration, since information regarding the air quality of the outdoor 32 is acquired through the communication unit 11, the information regarding the air quality of the outdoor 32 is measured by a device different from the ventilation support device 10, and the configuration of the ventilation support device 10 is simplified. .

  Furthermore, it is desirable that the ventilation support apparatus 10 includes a position detection unit 12 that obtains position information of the current position. In this ventilation support device 10, it is desirable that the communication unit 11 acquires information related to the air quality of the outdoor 32 using the position information.

  According to this configuration, by obtaining the current position of the ventilation support device 10, information about the air quality of the outdoor 32 at the current position obtained by the position detection unit 12 through the telecommunication line 40 such as the Internet or a mobile telephone network. It becomes possible to get. That is, by accessing a website that discloses information on air quality observed at a number of observation points, it is possible to easily obtain information on air quality. Therefore, it is not necessary to provide a sensor for measuring air quality, which leads to a reduction in cost for realizing the ventilation support device 10.

  The presentation device 16 preferably includes a display 161. The processing unit 13 is configured to generate recommended information representing an operation recommended for the facility 20 that changes the air quality of the indoor 31 of the building 30 according to the environmental information. The output unit 15 is configured to display the recommended information on the screen of the display 161. The facility 20 includes at least one of a ventilation device 21 for mechanical ventilation and a ventilation device 22 for natural ventilation.

  According to this configuration, since the recommended information displayed on the display device 161 represents an operation recommended for the facility 20, if the user views the recommended information and operates the facility 20, the air quality of the indoor 31 is compared. Can be kept clean. Further, since the user operates the facility 20, the facility 20 does not need a remote operation function, and can be used without changing the existing facility 20 used by the user.

  In the ventilation support device 10, the processing unit 13 generates recommended information regarding the equipment 20 when the air quality satisfies a predetermined determination criterion, and the output unit 15 displays the recommended information generated by the processing unit 13 on the display 161. It is desirable to display on the screen.

  According to this configuration, when the air quality of the outdoor 32 satisfies the determination criterion, the recommended information is displayed on the screen of the display 161. Therefore, if the outdoor 32 air quality deteriorates and ventilation becomes inconvenient, recommended information is displayed to stop ventilation, and if the outdoor 32 air quality improves and ventilation is possible, ventilation is performed. It is possible to display recommended information.

  Alternatively, in the ventilation support device 10, the processing unit 13 may predict whether or not the air quality satisfies the determination criterion based on the change tendency of the air quality with time. In this case, when the processing unit 13 predicts that the air quality satisfies the determination criterion, the output unit 15 desirably displays the recommended information on the screen of the display 161 before the air quality satisfies the determination criterion.

  According to this configuration, when the air quality is predicted to satisfy the determination criterion, the recommended information is displayed before the air quality satisfies the determination criterion. Therefore, in particular, when it is predicted that the air quality of the outdoor 32 will deteriorate and ventilation will become inconvenient, the user may operate the equipment 20 to stop ventilation before ventilation becomes inconvenient. It becomes possible. That is, the facility 20 can be operated without delay when the air quality deteriorates.

  The ventilation support apparatus 10 may include an instruction unit 17 that gives an instruction regarding an operation to the facility 20. The presentation device 16 preferably includes a touch panel 162 superimposed on the screen of the display device 161. When the processing unit 13 receives an operation input on the touch panel 162 during a period in which the output unit 15 displays the recommended information on the screen of the display device 161, the processing unit 13 gives an instruction to the equipment 20 through the instruction unit 17 according to the operation input.

  According to this configuration, the ventilation support device 10 can be used like a remote control device (commander) for the facility 20 to remotely operate the facility 20.

  When the ventilation support device 10 includes the instruction unit 17 that instructs the facility 20 to operate, the processing unit 13 generates recommended information regarding the facility 20 when the air quality satisfies a predetermined criterion. An instruction may be given to the facility 20 through the instruction unit 17 according to the content of the recommended information.

  According to this configuration, the facility 20 can be automatically controlled according to the air quality of the outdoor 32.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made according to design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it can be changed.
