  The integrated controller 10 includes a window information collection unit 11, a window open state determination unit 12, a notification unit 13, and a storage unit 14.

  The window information collection unit 11 collects window information from the window sensor 30 installed corresponding to the predetermined window 20 of each dwelling unit. For example, the window information collection unit 11 collects window information from each of the window sensors 30 installed in each of the dwelling units 101 to 104. That is, the window information collection unit 11 collects a plurality of window information by collecting window information from each of the plurality of window sensors 30.

  As described above, the window sensor 30 detects the open / closed state of the window 20. Therefore, the window information obtained from the window sensor 30 is information indicating the open / closed state of the window 20, for example, information indicating the window open state and information indicating the window closed state. The window open state changes from a state where the window 20 is opened (open state) or a state where the window 20 is closed (closed state) to a state where the window 20 is opened (open state). It is a state (closed / open transition state). On the other hand, the window closed state changes from a state in which the window 20 is closed (closed state) or a state in which the window 20 is open (open state) to a state in which the window 20 is closed (closed state). It is a state (opening / closing transition state).

  As an example, in FIGS. 1 and 2, the windows 20 of the dwelling units 101 and 103 are closed, and the windows 20 of the dwelling units 102 and 103 are open. Further, the window 20 of the dwelling unit 105 in FIG. 1 is in a closed / open transition state.

  The window open state determination unit 12 determines whether each window 20 of the plurality of dwelling units is in the window open state based on the window information collected by the window information collection unit 11. For example, when the window information collection unit 11 collects the window information (four window information) of each of the windows 20 of the dwelling units 101 to 104, the window open state determination unit 12 is based on the window information. Whether each window 20 of 104 is in an open state, that is, whether the window 20 is in an open state or a closed-open transition state, or whether the window 20 is in either an open state or a closed-open transition state. to decide.

  In the present embodiment, the integrated controller 10 determines whether the window 20 of each dwelling unit is in the window open state by the window open state determination unit 12, but further, the windows collected by the window information collection unit 11. Based on the information, it may be determined whether or not each window 20 of the plurality of dwelling units is in a window closed state.

  When the window open state determination unit 12 determines that at least one of the plurality of windows 20 corresponding to the plurality of dwelling units is in the window open state, the notification unit 13 determines a predetermined value for at least one user terminal 50 of the plurality of dwelling units. The information is notified. For example, when the window open state determination unit 12 determines that at least one of the windows 20 of the dwelling units 101 to 104 is in the window open state, the notification unit 13 notifies the user terminal 50 of the dwelling units 104 to 104 of predetermined information. And let them know.

  In the present embodiment, the integrated controller 10 notifies the user terminal 50 of predetermined information when it is determined that at least one of the plurality of windows 20 is in the window open state. When it is determined that a predetermined number of windows 20 are open, the user terminal 50 may be notified of predetermined information. In this case, for example, when the ratio of the windows 20 in the window open state among the plurality of windows 20 is equal to or greater than a predetermined value, the user terminal 50 may be notified of the predetermined information.

  The predetermined information notified by the user terminal 50 is, for example, the number of windows 20 that are currently open (two in FIG. 2) among the plurality of windows 20 that can collect the window information, or the window information. Is the ratio of the windows 20 that are in the window open state among the plurality of windows 20 that have been collected (50% (2/4) in FIG. 2).

  For example, the notified predetermined information is displayed on the user terminal 50, but the predetermined information displayed on the user terminal 50 may be the same information as the window information collected by the window information collecting unit 11. Different information may be used, or both the same information and different information may be used.

  The memory | storage part 14 memorize | stores the window information (opening-closing state) of the window 20 collected about each dwelling unit. For example, the storage unit 14 stores window information as shown in FIG. In FIG. 3, “open” indicates that the window 20 is open, and “closed” indicates that the window 20 is closed. The numbers shown in FIG. 3 indicate the number of windows 20 that are open or closed. In addition, in FIG. 3, the living room, the kitchen, and the child room are shown as an example of the living space, and the number when the living spaces of a plurality of dwelling units are grouped for each type of living room is shown for each floor.

  Next, control of the air quality monitoring system 1 and the air quality monitoring device (integrated controller 10) in the present embodiment will be described.

  First, the integrated controller 10 acquires information on the open / closed state of the windows 20 of each dwelling unit at the current time as window information by the window sensor 30 installed in each dwelling unit (room) of the apartment 100.

  Specifically, the window information collection unit 11 collects the window information of the window 20 from the window sensor 30 installed in each dwelling unit via the home controller 40 of each dwelling unit. Then, the window open state determination unit 12 determines whether or not the windows 20 of each dwelling unit are in the window open state based on the window information collected by the window information collection unit 11.

  Note that the window information of the window 20 obtained by the window sensor 30 may be set to notify the integrated controller 10 via the home controller 40 periodically or when the open / close state of the window 20 changes. Good.

  Next, the integrated controller 10 notifies the user terminal 50 of each dwelling unit of information regarding the open / closed state of the window 20 for another dwelling unit different from the dwelling unit based on the acquired information regarding the open / closed state of the window 20. The user terminal 50 is notified of predetermined information.

  Specifically, when the window open state determination unit 12 determines that at least one of the plurality of windows 20 corresponding to the plurality of dwelling units is in the window open state, the notification unit 13 notifies the user terminal 50 of each dwelling unit. The information about the window open state of the windows 20 of the plurality of dwelling units in the apartment 100 is notified and notified. The information regarding the window open state of the window 20 is notified by being displayed on the user terminal 50 (monitor) via the home controller 40, for example. In addition, the user terminal 50 (dwelling unit) to alert | report may be one, multiple may be sufficient, and all the houses may be sufficient.

  The user who owns the user terminal 50 notified of the information about the open / closed state of the window 20 is based on the information on the window open state of the window 20 notified by the user terminal 50, and the window of the window 20 of the user's own dwelling unit. Determine whether to open.

  For example, when the information about the open / closed state of the window 20 is information that there are many open windows 20, it can be assumed that other users are opening the window because the outside air is not dirty. Therefore, in this case, the user can determine that the indoor air quality can be improved by opening the window 20 of his / her dwelling unit.

  On the other hand, when the information regarding the open / closed state of the window 20 is information that there is almost no open window 20, it can be estimated that other users are not opening the window because the outside air is dirty. Therefore, in this case, the user can determine that the indoor air quality cannot be improved even if the window 20 of his / her dwelling unit is opened.

  As described above, the integrated controller 10 (air quality monitoring device) in the present embodiment includes the window information collection unit 11 that collects window information of the window 20 from the window sensor 30 of each dwelling unit of the apartment 100, and the window information collection.

Further, the air quality monitoring system 1 in the present embodiment includes the integrated controller 10.

  Therefore, according to the air quality monitoring system 1 and the integrated controller 10 in the present embodiment, it is possible to provide the user with appropriate information as to whether or not to open the window. Specifically, information regarding the open / closed state of the window 20 of each dwelling unit is notified to the user in real time as information as to whether or not it is suitable for opening a window.

  Thereby, since the user of the said dwelling unit can obtain the information regarding the window opening of the user (other person) of another dwelling unit, he can guess the state of the air quality of external air. Therefore, it is not possible to open the window when the air quality of the outside air is considered to be poor, and it is possible to open the window when the air quality of the outside air is considered to be good.

  That is, even if the air quality state of the outside air cannot be directly grasped, it is possible to appropriately open the window at a timing at which it can be estimated that the air quality of the outside air is good. As a result, the probability that the indoor air quality in the dwelling unit can be improved can be increased.

  In addition, according to the air quality monitoring system 1 and the integrated controller 10 in the present embodiment, it is possible to provide the user with future prediction information as to whether or not it is suitable for window opening. An indoor air quality improvement prediction (level, time) or deterioration prediction (level, time) can also be provided to the user.

The integrated controller 10A is communicable with each of the dwelling units 201 to 204. Specifically, the integrated controller 10A has the window sensor 30, the in-home controller 40, the user terminal 50, the in-house controller 40 in each dwelling unit, The air quality sensor 60 and the air quality improvement device 70 can communicate with each other.

  The in-home controller 40 communicates with the integrated controller 10A, and communicates with the window sensor 30, the user terminal 50, the air quality sensor 60, and the air quality improvement device 70 in each dwelling unit.

  In the present embodiment, the user terminal 50 is notified of window information of the windows 20 of each dwelling unit and information (air quality information) indicating the air quality of each dwelling unit from the integrated controller 10A. Specifically, information indicating the open / closed state of the window 20 in each dwelling unit and air quality information are transmitted (notified) to the user terminal 50 via the in-home controller 40 from the integrated controller 10A. The user terminal 50 displays the received information (information indicating the open / closed state of the window 20 and air quality information).

  The air quality sensor 60 detects the air quality of each dwelling unit. For example, the air quality sensor 60 detects the degree of air quality contamination in a room where the air quality sensor 60 is installed. Information indicating the air quality detected by the air quality sensor 60 is transmitted to the integrated controller 10A via the home controller 40.

  In this embodiment, since the window sensor 30 and the air quality sensor 60 are installed in each dwelling unit, the air quality is measured by periodically measuring the air quality after the window sensor 30 detects the opening of the window. It is possible to accumulate changes over time. Thereby, it can be grasped whether the air quality is deteriorating or improving.

  The air quality improving device 70 is, for example, an air cleaner. Operation control of the air quality improvement device 70 can be performed directly by the user pressing a switch or the like of the air quality improvement device 70, but can also be performed via the home controller 40.

That is, the air quality information collection unit 15 collects a plurality of air quality information by collecting the air quality information from each of the plurality of air quality sensors 60.

The air quality determination unit 16 determines the air quality of each of the plurality of dwelling units based on the air quality information collected by the air quality information collection unit 15. For example, when the air quality information collection unit 15 collects the air quality information of each of the dwelling units 201 to 204, the air quality determination unit 16 determines the air quality of the indoors of the dwelling units 201 to 204 based on the air quality information. The degree of air quality (contamination level) at the present time, the change in air quality over time (the inclination of air quality with respect to time), the degree of change in air quality, or the like is determined. By determining the change in air quality over time, it is possible to determine whether the air quality is rising and changing (improving) or whether the air quality is decreasing and changing (deteriorating). For example, the air quality determination unit 16 determines the degree, change, or degree of change of air quality by threshold processing. The degree of air quality (an index of the degree of contamination) is a value of PM2.5, Co ₂ value, temperature and humidity, volatile organic compounds (VOC) or dust.

  Further, the plurality of collected air quality information may be divided into necessary information and unnecessary information, and the air quality may be determined based on only necessary information. For example, the air quality information of the west side dwelling unit may be treated as necessary information, and the air quality information of the east side dwelling unit may be treated as unnecessary information. Moreover, the air quality information of the dwelling unit on the higher floor may be necessary information, and the air quality information of the dwelling unit on the lower floor may be treated as unnecessary information.

  Informing part 13 in this embodiment, when it is judged by window opening state judging part 12 that at least one of a plurality of windows 20 corresponding to each of a plurality of dwelling units is a window opening state, each of a plurality of dwelling units. The user terminal 50 is notified and notified of predetermined information.

  Furthermore, when the air quality determination unit 16 determines that the air quality of at least one of the plurality of dwelling units is in a bad state, the notification unit 13 notifies the user terminal 50 of each of the plurality of dwelling units of predetermined information. May be. For example, when the air quality determination unit 16 determines that the air quality of one of the plurality of houses continues in a bad state, the notification unit 13 or one of the plurality of houses When it is determined that the air quality has deteriorated, the user terminal 50 in another residence among the plurality of residences may be notified and notified of predetermined information.

  The predetermined information notified by the user terminal 50 is window information and air quality information in each dwelling unit. The window information is the same as in the first embodiment. The air quality information can be collected, for example, among the plurality of dwelling units (living spaces) from which the air quality information can be collected, the dwelling unit in which the air quality is currently bad (that is, the place where the air quality is bad), or the air quality information This is the ratio of dwelling units with poor air quality among multiple units. The state in which the air quality is poor includes not only the case where the air quality continues in a poor state but also the state in which the air quality has deteriorated (changed in a direction in which the air quality becomes dirty). Further, the place where the air quality is bad is, for example, the first floor or top floor dwelling unit or the north side or south side dwelling unit in the apartment 200. Note that the predetermined information notified by the user terminal 50 may include the degree to which the air quality has deteriorated.

  Moreover, the memory | storage part 14 in this Embodiment memorize | stores not only the window information (opening-closing state) of the window 20 collected about each dwelling unit but the air quality information collected about each dwelling unit. For example, the storage unit 14 stores air quality information about living spaces such as living rooms, kitchens, and child rooms in each dwelling unit.

  Next, control of the air quality monitoring system 2 and the air quality monitoring device (integrated controller 10A) in the present embodiment will be described.

  First, the integrated controller 10A acquires information on the air quality of each dwelling unit at the current time by the air quality sensor 60 installed in each dwelling unit (room) of the apartment 200.

  Specifically, the air quality information collection unit 15 collects air quality information from the air quality sensor 60 installed in each dwelling unit via the home controller 40 of each dwelling unit. The air quality determination unit 16 determines the air quality of each dwelling unit based on the air quality information collected by the air quality information collection unit 15.

  Note that the air quality information obtained by the air quality sensor 60 may be set to notify the integrated controller 10A via the home controller 40 periodically or when the air quality changes.

  Next, in the integrated controller 10 </ b> A, when the air quality determination unit 16 determines that at least one air quality of the plurality of dwelling units is in a bad state, the window open state determination unit 12 sets the windows 20 of the plurality of dwelling units. Based on the window information collected from the corresponding installed window sensor 30, it is determined whether or not the windows 20 of the plurality of dwelling units are in the window open state.

  Next, in the integrated controller 10 </ b> A, when the window open state determination unit 12 determines that at least one of the plurality of windows 20 is in the window open state, the notification unit 13 sends predetermined information to the user terminals 50 of the plurality of dwelling units. To let you know.

  For example, the notification unit 13 notifies the user terminal 50 in another dwelling unit of the air quality information in one dwelling unit and the information on the open / closed state of the window 20 as the predetermined information. The air quality information and information about the open / closed state of the window 20 are displayed on the user terminal 50 (monitor) via the home controller 40, for example.

  The user who owns the user terminal 50 informed of the air quality information and the information regarding the open / closed state of the window 20 is based on the air quality information notified to the user terminal 50 and the information regarding the open / closed state of the window 20. It is determined whether to open the window 20 of the dwelling unit.

  For example, as information on the open / closed state of the window 20 of another dwelling unit, there is a large amount of information on the open state in which the window 20 is open among the window open states, and the air quality information of other dwelling units is air. When there is a lot of information that the quality is good, it can be assumed that the user of another dwelling unit is opening the window because the outside air is not dirty. Therefore, in this case, the user can determine that the indoor air quality can be improved by opening the window 20 of his / her dwelling unit.

  In particular, when information about the open / closed state of the windows 20 of other dwelling units includes the window 20 in the closed / open transition state, which is a state that changes from the closed state to the open state, the current outside air is not contaminated. The user can guess that the window 20 is opened.

  In addition, when the air quality information is information that the air quality of other dwelling units is bad or deteriorated while the information that the window 20 is open is included, the outside air is dirty, or It can be inferred that there are factors in the dwelling units that degrade air quality.

  On the other hand, when the information regarding the open / closed state of the windows 20 of other dwelling units is information that there are almost no open windows 20, it can be estimated that other users are not opening the windows because the outside air is dirty. Therefore, in this case, the user can determine that the indoor air quality cannot be improved even if the window 20 of his / her dwelling unit is opened.

  In this case, the air quality information that is reported is information that there are many dwelling units with poor air quality, or that the air quality of other dwelling units is worse than the air quality of its own dwelling unit.
