Description

The present invention relates to a building notification system.

In recent years, a technique has been proposed in which the amount of dust indoors is detected by a dust sensor, and based on the detected amount of dust, dust is removed indoors by a self-propelled vacuum cleaner or the like (for example, Patent Document 1, 2). According to this technique, it is possible to suitably clean the interior.

JP-A-2015-197250 Japanese Unexamined Patent Publication No. 2015-205681

By the way, when a window is opened in a building to ventilate indoors, it is conceivable that dust may flow from the outside to the inside through the window. In such a case, even if the above-mentioned cleaning technique is applied, the removal of dust cannot keep up, and as a result, dust may be accumulated indoors.

Therefore, in such a case, it is necessary to close the window to prevent dust from flowing from outdoors to indoors, but when dust is flowing from outdoors to indoors, people indoors will notice it. Is considered difficult. Therefore, it is considered difficult for a person indoors to close the window to prevent the inflow of dust from the outside.

The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a building notification system capable of preventing the inflow of dust from the outside.

In order to solve the above problems, the building notification system of the first invention is applied to a building provided with a plurality of windows communicating indoors and outdoors and a plurality of opening / closing bodies provided in each of the windows. An opening / closing determining means for determining whether or not at least one of the opening / closing bodies is in the open state, a dust amount acquiring means for acquiring the amount of dust indoors, and at least one of the opening / closing bodies by the opening / closing determining means. When it is determined that is in the open state, the amount of indoor dust acquired by the dust amount acquisition means and the amount of indoor dust generated indoors are determined in advance as the amount of indoor dust generated from the outside. The opening / closing body that is opened to the user based on a calculation means for calculating the amount of outdoor inflow dust, which is the amount of dust flowing into the room through the window, and the amount of outdoor inflow dust calculated by the calculation means. It is characterized by comprising a notification control means for performing a notification process for prompting the user to close the window.

Indoor dust includes indoor dust generated indoors and outdoor inflow dust that has flowed indoors from the outdoors. Therefore, in the present invention, paying attention to this point, the amount of dust generated indoors is set in advance as the reference amount of dust generated indoors, and when at least one of the opening / closing bodies is in the open state, the amount of dust is generated. Based on the indoor dust amount (measured value of the dust amount) acquired by the acquisition means and the indoor dust generation reference amount, the outdoor inflow dust amount flowing from the outside to the indoor through the opened window is calculated. It is said. Then, based on the calculated amount of outdoor inflow dust, a notification process is performed to urge the user to close the open / close body that is in the open state. In this case, when the amount of dust flowing from the outside to the inside is large, the user can take measures to prevent the dust from flowing in from the outside by closing the opening / closing body by performing the notification process. Therefore, it is possible to prevent dust from flowing in from the outside.

In the building notification system of the second invention, in the first invention, the indoor dust generation reference amount is determined for each period in one year, and the calculation means is the indoor of the period to which the present belongs. It is characterized in that the outdoor inflow dust amount is calculated based on the generated dust reference amount.

The amount of dust generated indoors (the amount of dust generated indoors) may vary depending on the season. For example, in winter, the amount of fiber waste generated from clothing increases, so it is possible that the amount of dust generated indoors will increase accordingly. Therefore, in the present invention, the indoor dust standard amount is set for each period in one year, and the outdoor inflow dust amount is calculated based on the indoor dust standard amount of the period to which the present belongs. In this case, it is possible to calculate the amount of outdoor inflow dust with high accuracy in consideration of the amount of indoor dust generated for each season.

In the first or second invention, the building notification system of the third invention is the dust amount when the open / close determination means determines that each of the open / close bodies is in a fully closed state. Based on the storage execution means for carrying out the storage process of storing the indoor dust amount acquired by the acquisition means in the storage means as dust amount data and the dust amount data stored in the storage means, the indoor dust generation standard. It is characterized by comprising a setting means for setting an amount.

According to the present invention, when each opening / closing body is fully closed, that is, when the inflow of dust from the outside to the inside through the window is blocked, the indoor is acquired by the dust amount acquisition means. The amount of dust is stored in the storage means as dust amount data. In this case, the dust amount data (indoor dust amount) stored in the storage means is considered to be close to the dust amount generated indoors (indoor dust amount). Then, since the indoor dust generation reference amount is set based on the dust amount data stored in the storage means, an amount close to the dust amount actually generated indoors (inside the building) is set as the indoor dust generation reference amount. be able to. This makes it possible to calculate the amount of outdoor inflow dust with high accuracy according to the building (building scale, etc.).

In the third invention, the building notification system of the fourth invention measures the duration of the fully closed state when each of the opened / closed bodies is determined to be in the fully closed state by the open / close determining means. The storage executing means includes means, and the storage performing means executes the storage process when the duration measured by the measuring means exceeds a predetermined time.

According to the present invention, the duration of the fully closed state of each open / close body is measured, and when the measured duration exceeds a predetermined time, the amount of indoor dust acquired by the dust amount acquisition means is It is stored in the storage means as dust amount data. In this case, when the inflow of dust from the outside to the inside is blocked for a certain period of time, the amount of dust inside the room is acquired and stored, so the stored dust amount data is closer to the amount of dust actually generated indoors. It is thought that Therefore, the indoor dust reference amount set based on the dust amount data can be set to an amount even closer to the amount of dust actually generated indoors.

In the fourth invention, the building notification system of the fifth invention determines whether or not the open state is temporary when any of the open / close bodies is determined to be in the open state by the open / close determination means. When it is determined that the open state of the opening / closing body is temporary, the measuring means continues to fully close the opening / closing body before and after the open state. It is characterized in that the duration is measured as if it were present.

In a window portion where a person can enter and exit, such as a sweep-out window, it is conceivable that the opening / closing body is temporarily opened when a person enters and exits through the window portion. While such temporary opening is performed at a relatively high frequency, it is considered that the amount of dust flowing in from the outside through the window during the temporary opening is extremely small. Therefore, in view of this point, in the present invention, when the opening / closing body is opened, it is determined whether or not the opening is temporary, and when it is determined that the opening is temporary, the opening is opened. It is assumed that the fully closed state of the open / close body is continued in the front and rear, and the duration is measured. In this case, since it is possible to avoid losing the opportunity to store (accumulate) the dust amount data due to the temporary opening, it is possible to preferably store the dust amount data.

In any of the third to fifth inventions, the building notification system of the sixth invention includes means for determining whether or not indoor cleaning has been performed in the fully closed state, and the storage execution means It is characterized in that the storage process is performed after it is determined that the indoor cleaning has been performed.

According to the present invention, after the indoor cleaning is performed in the fully closed state, the indoor dust amount acquired by the dust amount acquiring means is stored as the dust amount data. In this case, even if dust flows from the outside to the inside when the opening / closing body is open, the dust amount data can be stored after removing the inflowing dust to some extent, so that the dust amount data includes the outdoor inflow amount. It can be stored in an amount close to the amount of dust generated indoors.

In the building notification system of the seventh invention, in any of the third to sixth inventions, the indoor dust generation reference amount is determined for each period in one year, and the setting means is stored in the storage means. It is characterized in that the indoor dust generation reference amount of the predetermined time is set based on the dust amount data of the predetermined time.

According to the present invention, the indoor dust generation reference amount at a predetermined time is set based on the dust amount data at a predetermined time stored in the storage means. In this case, the reference amount of indoor dust generated for each period can be set to an amount close to the amount of dust actually generated indoors for each period.

In the building notification system of the eighth invention, in any of the third to seventh inventions, the indoor dust generation reference amount is set for each period in one year, and the indoor dust generation is the amount of dust generated indoors. How the dust amount changes for each period The dust amount transition data showing the tendency of the transition is stored in advance, and any one of the dust amount transition data is referred to and stored in the storage means. The setting means includes an estimation means for estimating the amount of indoor dust generated in the remaining time based on the dust amount data of the said time, and the setting means is based on the estimation result by the estimating means and said the indoor dust generated in the remaining time. It is characterized by setting a reference amount.

According to the present invention, the amount of indoor dust generated in the remaining period is estimated based on the dust amount data of any period stored in the storage means with reference to the dust amount transition data prepared in advance. Then, based on the estimation result, the reference amount of indoor dust generated in the remaining period is set. In this case, even if only one of the above periods has passed since the system was installed in the building, the standard amount of indoor dust generated in the remaining period is set indoors in that period based on the dust amount data at that period. The amount can be set close to the amount of dust generated.

In any one of the first to eighth inventions, the building notification system of the ninth invention opens and closes windows to neighboring residents living in the vicinity of the building based on the amount of outdoor inflow dust calculated by the calculation means. It is characterized by having an advice means for sending advice on.

If the amount of dust that flows into a building from the outside is large, it is possible that the amount of dust that is scattered outdoors around the building is large, so dust can also be collected from the outside through windows in buildings near the building. It is considered that there is a high possibility of inflow. Therefore, in view of this point, in the present invention, advice regarding opening and closing of windows is sent to the neighbors of the building based on the amount of outdoor inflow dust calculated in the building. In this case, for example, when the amount of dust flowing outdoors is large, it is possible to advise neighboring residents to close the windows, so that it is possible to prevent dust from flowing into the building of the neighboring residents from the outside. It will be possible.

Is targeted for cleaning.

Subsequently, the electrical configuration of the notification system will be described with reference to FIG. FIG. 2 is a diagram showing an electrical configuration of the notification system.

As shown in FIG. 2, the notification system includes a controller 50 as a notification control means. The controller 50 is configured to include a well-known microcomputer having a CPU or the like, and is provided on the wall surface of the living room 15, for example.

The controller 50 includes a reference amount storage unit 51, a dust amount data storage unit 52, and a communication unit 53. The reference amount storage unit 51 stores a predetermined indoor dust reference amount as the amount of dust generated indoors. In the present embodiment, the indoor dust reference amount is set for each month in one year, and the indoor dust reference amount for each month is stored in the reference amount storage unit 51. Specifically, as shown in FIG. 3, the reference amount storage unit 51 stores the indoor dust reference amount for each month as a reference amount table.

The dust amount data storage unit 52 stores the indoor dust amount detected by the dust sensor 42 as dust amount data. Specifically, as will be described later, the dust amount data storage unit 52 collects dust amount data in the room detected by the dust sensor 42 in a fully closed state in which each glass door 27 is in a fully closed state. Remember as. Then, the controller 50 sets and updates the indoor dust reference amount α stored in the reference amount storage unit 51 based on the dust amount data stored in the dust amount data storage unit 52. The dust amount data storage unit 52 corresponds to the storage means.

The communication unit 53 is capable of wireless communication with each self-propelled vacuum cleaner 47. As described above, the self-propelled vacuum cleaner 47 has a built-in vacuum cleaner controller 48, and the vacuum cleaner controller 48 has a communication function capable of wireless communication with the communication unit 53. When the vacuum cleaner controller 48 receives the cleaning start signal transmitted from the controller 50, the self-propelled vacuum cleaner 47 starts the cleaning process, and when the cleaning process is completed, the vacuum cleaner controller 48 transmits the cleaning end signal to the controller 50.

Each open / close sensor 41 and each dust sensor 42 are connected to the controller 50. Sequential detection results are input to the controller 50 from these sensors 41 and 42. The controller 50 determines whether or not at least one of the glass doors 27 is in the open state based on the detection result from each open / close sensor 41.

A notification device 45 is connected to the controller 50. When it is determined that at least one of the glass doors 27 is in the open state in the above determination, the controller 50 detects the detection result from each dust sensor 42 and the indoor generation stored in the reference amount storage unit 51. Based on the dust reference amount, the amount of dust flowing from the outside to the inside through the window 26 (hereinafter, also referred to as the amount of dust flowing outdoors) is calculated, and the notification process is performed by the notification device 45 based on the calculation result.

Further, in the above determination, when it is determined that each glass door 27 is in the fully closed state, the controller 50 uses the indoor dust amount detected by the dust sensor 42 as the dust amount data and the dust amount data storage unit 52. Remember in.

Next, the content of the control process executed by the controller 50 will be described with reference to FIG. FIG. 4 is a flowchart showing the control process. This process is repeatedly executed at a predetermined cycle.

As shown in FIG. 4, first, in step S11, it is determined whether or not at least one of the glass doors 27 is in the open state based on the detection result from each open / close sensor 41 (as an open / close determination means). Equivalent). In other words, in this step, it is determined whether or not any of the glass doors 27 is opened and indoor ventilation is performed through the window portion 26. If at least one of the glass doors 27 is in the open state, the process proceeds to step S12, and the window opening process is executed. On the other hand, when each glass door 27 is in the fully closed state, the process proceeds to step S13, and the window fully closed processing is executed. After the process of step S12 or step S13, this process ends.

Subsequently, the window opening process in step S12 and the window fully closing process in step S13 will be described. First, the window opening process will be described with reference to FIG. FIG. 5 is a flowchart showing the window opening process.

As shown in FIG. 5, first, in step S21, the indoor dust amount is acquired based on the detection result from each dust sensor 42 (corresponding to the dust amount acquisition means). Specifically, based on the detection result from each dust sensor 42, the average value of the indoor dust amount detected by each of the dust sensors 42 is calculated, and the calculated average value is used as the indoor dust amount (dust amount). (Measured value of).

In step S22, the indoor dust reference amount α corresponding to the current month is read out from the reference amount storage unit 51.

In step S23, the amount of dust flowing from the outside to the inside through the window 26 (outdoor inflow) based on the indoor dust amount (measured value) acquired in step S21 and the indoor dust reference amount α read out in step S22. Calculate the amount of dust) (corresponding to the calculation means). Specifically, the outdoor inflow dust amount is calculated by subtracting the indoor dust generation reference amount α from the acquired indoor dust amount (measured value of indoor dust amount-indoor dust generation standard amount α = outdoor inflow dust amount). ).

In step S24, it is determined whether or not the calculated amount of outdoor inflow dust exceeds a predetermined reference value. Here, the predetermined reference value is a value defined as an allowable upper limit value of the amount of dust flowing from outdoors to indoors, and when the amount of dust equal to or less than this reference value flows from outdoors to indoors, it is indoors. The comfort is maintained. If the amount of dust flowing into the outdoors is equal to or less than the predetermined reference value, this process is terminated, and if it exceeds the predetermined reference value, the process proceeds to step S25.

In step S25, a notification process for urging the resident to close the glass door 27 that is in the open state is executed (corresponding to the notification control means). In this notification process, by outputting a notification signal to the notification device 45, the device 45 urges the glass door 27 to be closed by voice. For example, make an announcement such as "Please close the window" or "Dust is flowing in from the outside". After this notification process, this process ends.

Subsequently, the window fully closed processing (step S13) will be described with reference to FIG. FIG. 6 is a flowchart showing the processing when the window is fully closed.

As shown in FIG. 6, first, in step S31, it is determined whether or not the stored flag (the flag set in step S40 described later) is set. If the stored flag is set, this process ends, and if the stored flag is not set, the process proceeds to step S32.

In step S32, a fully closed timer (corresponding to the measuring means) is set. As a result, when each glass door 27 is fully closed, time counting by the fully closed timer is started. At this time, if the time counting by the fully closed timer has already been executed, the time counting is continued as it is.

In step S33, the communication unit 53 transmits a cleaning start signal to the vacuum cleaner controller 48 of each self-propelled vacuum cleaner 47. When this cleaning start signal is received by the vacuum cleaner controller 48, the cleaning process by the self-propelled vacuum cleaner 47 is started by the controller 48.

In step S34, it is determined whether or not the glass door 27a of the balcony 38 is in the open state based on the detection result from the open / close sensor 41 (of the glass door 27a). When the glass doors 27a of the balcony 38 are closed, that is, when each glass door 27 is fully closed, the process proceeds to step S35.

In step S35, it is determined whether or not the cleaning process by the self-propelled vacuum cleaner 47 is completed. This determination is made based on whether or not a cleaning end signal is received from the vacuum cleaner controller 48 of each self-propelled vacuum cleaner 47. When the cleaning process by the self-propelled vacuum cleaner 47 is completed, the process proceeds to step S36, and when the cleaning process is not completed, the main process is ended.

In step S36, the cleaning end timer is set, and the time counting by the timer is started. At this time, if the time counting by the cleaning end timer has already been executed, the time counting is continued as it is.

In the following step S37, it is determined whether or not the elapsed time from the start of time counting by the cleaning end timer exceeds a predetermined time. That is, here, it is determined whether or not a predetermined time has elapsed since the cleaning process by the self-propelled vacuum cleaner 47 was completed. The predetermined time is set to, for example, about 30 minutes to 2 hours. If a predetermined time has elapsed since the cleaning process was completed, the process proceeds to step S38, and if the predetermined time has not elapsed, the present process is terminated.

In step S38, it is determined whether or not the elapsed time from the start of time counting by the fully closed timer exceeds a predetermined time. That is, here, it is determined whether or not a predetermined time has elapsed since each glass door 27 was fully closed. The predetermined time is set to, for example, about 4 to 8 hours. If a predetermined time has elapsed since each glass door 27 was fully closed, the process proceeds to step S39, and if the predetermined time has not elapsed, this process ends.

In step S39, the amount of indoor dust (actual measurement value) is acquired based on the detection result from each dust sensor 42, and the acquired indoor dust amount is stored in the dust amount data storage unit 52 as dust amount data. Perform amnestics (corresponds to amnestics). In this case, when acquiring the indoor dust amount, the average value of the dust amount detected by each dust sensor 42 is calculated based on the detection result from each dust sensor 42 as in step S21 (FIG. 4). Then, the calculated average value is acquired as the amount of dust in the room.

In the following step S40, a stored flag indicating that the storage process has been performed is set. After that, this process ends. The stored flag is reset when it is determined in step S11 of FIG. 4 that any of the glass doors 27 is in the open state.

In the previous step S34, when the glass door 27a of the balcony 38 is in the open state, the process proceeds to step S41, and a standby process of waiting for a predetermined time to elapse is performed. In this case, the predetermined time is set to a sufficient time required for opening the glass door 27a and entering and exiting between the master bedroom 31 and the balcony 38 through the window portion 26a, for example, about 5 to 10 seconds. ..

In the following step S42, it is determined whether or not the glass door 27a of the balcony 38 is closed based on the detection result from the open / close sensor 41 (of the glass door 27a). When the glass door 27a of the balcony 38 is closed, it can be considered that the glass door 27a is temporarily opened in order to enter and exit the balcony 38 through the window portion 26a. Therefore, in this case, it is assumed that the inflow of dust from the outside through the window portion 26a does not occur, and the process proceeds to step S35. That is, in this case, the time counting by the fully closed timer (and the cleaning end timer) is continuously performed before and after the open state of the glass door 27a.

On the other hand, when the glass door 27a of the balcony 38 is in the open state, it can be considered that the glass door 27a is continuously opened in order to ventilate the room through the window portion 26a. Therefore, in this case, it is assumed that dust may flow in from the outside, and the process proceeds to step S43 to reset (stop) the fully closed timer and the cleaning end timer. After that, this process ends.

Next, the reference amount setting process executed by the controller 50 will be described with reference to FIG. 7. FIG. 7 is a flowchart showing a reference amount setting process. The reference amount setting process is a process of setting (setting update) the indoor dust generation reference amount α based on the dust amount data stored in the dust amount data storage unit 52. This process is started when the predetermined set timing is reached. In the present embodiment, the setting timing is set once a month on a predetermined day, for example, the first day of the month (that is, the first day).

As shown in FIG. 7, first, in step S51, it is determined whether or not the current setting is the initial setting. That is, it is determined whether or not this setting is the first setting process since the introduction of this notification system. If this setting is the initial setting, the process proceeds to step S52 to perform the reference amount table creation process. Hereinafter, this reference amount table creation process will be described with reference to FIGS. 8 and 9. FIG. 8 is a flowchart showing a reference quantity table creation process. FIG. 9 is a diagram for explaining the flow of the reference amount setting process.

As shown in FIG. 8, first, in step S61, the dust amount data (measured value) of the previous month is read out from the dust amount data storage unit 52. For details, read all the dust amount data of the previous month. Here, it is assumed that this notification system was introduced in the building 10 in June (for example, the beginning of June), and therefore the first setting process (reference amount) is performed in July (specifically, July 1). Setting process) is to be carried out. Therefore, in this step, all the dust amount data for June is read from the dust amount data storage unit 52.

In step S62, based on the dust amount data of the previous month (that is, the dust amount data of June), the indoor dust generation reference amount α of the previous month (June) is set (corresponding to the setting means). In this case, first, the average value of each dust amount data of the previous month read out is calculated, and the indoor dust generation reference amount α of the previous month is set based on the average value of the calculated dust amount data. Specifically, the average value of the calculated dust amount data is set (stored) in the reference amount storage unit 51 as the indoor dust amount reference amount α of the previous month. In FIG. 9A, the dust amount data (average value) in June is indicated by a diagonally hatched bar (bar), and the indoor dust amount reference amount α in June is indicated by a dot-hatched bar. ..

In step S63, an estimation process for estimating the amount of dust generated indoors (hereinafter, also referred to as the amount of dust generated indoors) in each of the remaining months (that is, each month other than June) is performed (corresponding to the estimation means). In this estimation process, the indoor dust amount for each remaining month is estimated using the initial table for the indoor dust amount initially registered in the storage area of the controller 50 in advance.

FIG. 10 shows the initial table. As shown in FIG. 10, the initial table is dust amount transition data showing the tendency of the transition of the indoor dust amount for each month in one year. The initial table is, for example, statistical data created by measuring the amount of dust actually generated indoors (inside a building) for a plurality of buildings every month and based on the measured measurement data. For convenience, FIG. 9 also shows the amount of indoor dust generated in each month on the initial table by a bar painted in black.

In FIG. 10, in addition to the transition of the amount of indoor dust generated for each month, the breakdown of the amount of dust generated for each type of dust is shown (By the way, such a breakdown is not stored in the actual initial table). According to this breakdown, for example, the amount of hair and dandruff generated is stable throughout the year. In addition, it can be seen that the amount of textile waste generated in clothing and the like increases in winter. Moreover, it can be seen that the amount of fiber debris generated in clothing and the like is larger than the amount of hair / dandruff and mites generated. Therefore, as a result, it can be seen that the amount of dust generated indoors tends to be larger in winter than in summer.

In the estimation process of step S63, referring to the initial table, based on the dust amount data (specifically, the average value) of the previous month (June) read out in step S61, the remaining months (January to May and). Estimate the amount of indoor dust generated from July to December). Specifically, the dust amount ratio between the dust amount data of the previous month (June) and the indoor dust amount of the previous month (June) in the initial table (dust amount ratio = dust amount data of the previous month / in the initial table) The amount of indoor dust generated in the previous month) is calculated, and the amount of indoor dust generated in the remaining months is calculated based on the calculated dust amount ratio. More specifically, the amount of indoor dust generated in the remaining months in the initial table is calculated (estimated) by multiplying the amount of indoor dust generated in the remaining months by the above-calculated dust amount ratio. In FIG. 9A, the estimated amount of indoor dust generated in each of the remaining months (that is, January to May and July to December) is shown by a white bar.

In step S64, the indoor dust reference amount α of the remaining month is set (corresponding to the setting means) based on the indoor dust amount of the remaining month estimated in step S63 for each remaining month. Here, the estimated amount of indoor dust generated in the remaining month is stored in the reference amount storage unit 51 as the indoor dust reference amount α of the remaining month. As a result, the indoor dust reference amount α for each month is stored in the reference amount storage unit 51, and specifically, is stored as a reference amount table (see FIG. 3). In FIG. 9A, the reference amount α of indoor dust generated in each of the remaining months (January to May and July to December) is shown by a dot-hatch bar. After that, this process ends.

By the way, in the month (June) when this system was introduced, the standard amount table has not been created yet (that is, the indoor dust standard amount α has not been set), so in the month of introduction, the initial table The amount of indoor dust generated in the month of introduction in the above is tentatively set as the indoor dust reference amount α.

Returning to the description of FIG. 7, in step S51, if the current setting is not the initial setting, that is, if the current setting is the second and subsequent settings, the process proceeds to step S53. In step S53, the dust amount data (measured value) of the previous month is read out from the dust amount data storage unit 52. For details, read all the dust amount data of the previous month. For example, if this is the second setting, that is, if this setting is implemented in August (specifically, August 1st), the dust amount data for July is stored in the dust amount data. Read from unit 52.

In step S54, the indoor dust reference amount α of the previous month (July) is set and updated (corresponding to the setting means) based on the dust amount data of the previous month (for example, the dust amount data of July). In this case, the average value of each dust amount data of the previous month read out is calculated, and the indoor dust reference amount α is set and updated based on the average value of the calculated dust amount data. Specifically, the average value of the calculated dust amount data is stored in the reference amount storage unit 51 as the indoor dust amount reference amount α. In this case, since the indoor dust reference amount α is already stored in the reference amount storage unit 51, the indoor dust reference amount α is overwritten and stored as a new indoor dust reference amount α. In FIG. 9B, the dust amount data (average value) in July is indicated by a diagonally hatched bar (bar), and the indoor dust amount reference amount α in July is indicated by a dot-hatched bar. ing. After that, this process ends.

According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

Based on the detection result from each open / close sensor 41, it is determined whether or not at least one of the glass doors 27 is in the open state, and as a result of the determination, any of the glass doors 27 is in the open state. If so, the opened window portion is based on the indoor dust amount (measured value of the dust amount) acquired based on the detection result from each dust sensor 42 and the predetermined indoor dust generation reference amount. From 26, the amount of outdoor dust flowing from the outside to the inside is calculated. Then, when the calculated amount of outdoor inflow dust exceeds a predetermined reference value, a notification process is performed to urge the resident (corresponding to the user) to close the glass door 27 which is in the open state. As a result, when the amount of dust flowing in outdoors is large, the resident can take measures to prevent the dust from flowing in from the outside by closing the glass door 27. Therefore, it is possible to prevent dust from flowing in from the outside.

Obtained based on the detection result from each dust sensor 42 when each glass door 27 is fully closed, that is, when the inflow of dust from the outside to the inside through the window 26 is blocked. The indoor dust amount is stored in the dust amount data storage unit 52 as dust amount data. In this case, it is considered that the dust amount data (indoor dust amount) stored in the dust amount data storage unit 52 is close to the dust amount generated indoors (indoor dust amount). Then, based on the dust amount data stored in the dust amount data storage unit 52, the indoor dust generation reference amount is set. In this case, since the amount of dust actually generated indoors (inside the building 10) can be set as the reference amount of dust generated indoors, the amount of dust inflowing outdoors with high accuracy according to the building (building scale, etc.) Can be calculated.

The duration of the fully closed state of each glass door 27 (specifically, the elapsed time from the start of time counting by the fully closed timer) is measured, and when the measured duration exceeds a predetermined time, each dust sensor 42 The amount of indoor dust acquired based on the detection result of is stored as dust amount data. In this case, when the inflow of dust from the outside to the inside is blocked for a certain period of time, the amount of dust inside the room is stored, so that the stored dust amount data is closer to the amount of dust actually generated indoors. Conceivable. Therefore, the indoor dust reference amount set based on the dust amount data can be set to an amount even closer to the amount of dust actually generated indoors.

When the glass door 27a (sweep window) of the balcony 38 is opened, it is determined whether or not the open state is temporary, and if it is determined to be temporary, the open state is determined. It was assumed that the fully closed state of the glass door 27a was continued before and after, and the time counting by the fully closed timer was continued (in other words, the duration of the fully closed state was measured). In this case, since it is possible to avoid losing the opportunity to store (accumulate) the dust amount data due to the temporary opening, it is possible to preferably store the dust amount data.

It is determined whether or not the cleaning process by the self-propelled vacuum cleaner 47 has been performed (finished) when each glass door 27 is fully closed, and as a result of the determination, when the cleaning process is performed, each dust sensor The amount of indoor dust acquired based on the detection results of 42 is stored as dust amount data. In this case, even if dust flows from the outside to the inside when the glass door 27 is open, the dust amount data can be stored after removing the inflowing dust to some extent. It can be stored in an amount close to the amount of indoor dust that is not included.

The indoor dust standard amount was set for each month (each period) in a year, and the outdoor inflow dust amount was calculated based on the indoor dust standard amount for the current month. In this case, it is possible to calculate the amount of outdoor inflow dust with high accuracy in consideration of the amount of indoor dust generated for each season.

Based on the dust amount data of a predetermined month stored in the dust amount data storage unit 52, the indoor dust generation reference amount of the predetermined month is set. In this case, the reference amount of indoor dust generated for each month can be set to an amount close to the amount of dust actually generated indoors for each month.

Refer to the initial table registered in advance, and based on the dust amount data of the introduction month (June) of this notification system stored in the dust amount data storage unit 52, the remaining months (January to May and July to 12). The amount of indoor dust generated in the month) was estimated. Then, based on the estimation result, the standard amount of indoor dust generated in the remaining months was set. In this case, even if only the above-mentioned introduction month (June) has passed since the introduction of this notification system in the building 10, the indoor dust reference amount for the remaining months is used by using the dust amount data of the introduction month. Can be set in an amount close to the amount of indoor dust generated in the remaining month.

The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

(1) In the above embodiment, an estimation process is performed to estimate the amount of indoor dust generated in each of the remaining months based on the dust amount data of the introduction month in which the system is introduced by referring to the initial table registered in advance. , Such estimation processing does not necessarily have to be performed. In this case, since it is not possible to set the indoor dust reference amount α for the remaining months based on the result of the estimation process, the indoor dust reference amount α is set by the same process as in steps S53 and S54 of FIG. Can be considered.

(2) In the above embodiment, the average value of each dust amount data of the previous month read from the dust amount data storage unit 52 is calculated, and the average value of the calculated dust amount data is used as the indoor dust reference amount α of the previous month. Although it has been set (step S54 in FIG. 7), for example, the value obtained by multiplying the average value of the calculated dust amount data by a predetermined coefficient (correction coefficient) may be used as the indoor dust amount reference amount α. In this case, the correction coefficient may be greater than or less than 1.

(3) In the above embodiment, the indoor dust reference amount α is set (updated) based on the dust amount data stored in the dust amount data storage unit 52, but the indoor dust reference amount α is not necessarily set. It is not necessary to set based on the dust amount data. For example, the indoor dust reference amount α may be set in advance for each month, and the set indoor dust reference amount α for each month may be set as a fixed value.

(4) The indoor dust standard amount α does not necessarily have to be set for each month (each period) in one year, and may be set every three months or every four months, for example. Further, the indoor dust reference amount α may be set to the same value for one year.

(5) In the above embodiment, when the duration of the fully closed state of each glass door 27 exceeds a predetermined time, a storage process for storing the amount of dust indoors as dust amount data is performed. The storage process (step S39 in FIG. 6) may be performed immediately after the glass door 27 is fully closed. Even in that case, since the dust amount data is stored in a state where the inflow of dust from the outside is blocked, it is considered that the dust amount data is close to the dust amount generated indoors.

(6) In the above embodiment, after the cleaning process by the self-propelled vacuum cleaner 47 is performed, the dust amount data storage process (step S39 in FIG. 6) is performed, but the self-propelled vacuum cleaner 47 is provided. In the building 10 which is not used, the dust amount data may be stored after the indoor cleaning by a non-self-propelled vacuum cleaner such as a canister type. In this case, the non-self-propelled vacuum cleaner is provided with a cleaning end switch so that when the switch is operated by a resident who performs cleaning, the non-self-propelled vacuum cleaner transmits a cleaning end signal to the controller 50. Can be considered.

It should be noted that the storage process of the dust amount data does not necessarily have to be performed after the cleaning process is performed.

(7) In the above embodiment, the notification device 45 in the building 10 is used to notify the resident to close the glass door 27 in the open state. For example, a smartphone, a mobile phone, or the like carried by the resident. You may go to a mobile terminal.

(8) In the above embodiment, dust sensors 42 are provided at a plurality of locations in the building 10, and the average value of the dust amount detected by each of these dust sensors 42 is acquired as the indoor dust amount (actual measurement value). However, for example, only one dust sensor 42 may be provided in the building 10, and the amount of dust detected by the one dust sensor 42 may be acquired as the amount of indoor dust.

(9) The building 10 may be provided with an air-conditioning system for the entire building that air-conditions a plurality of rooms (indoor spaces) by a common air-conditioning device. Further, the building 10 may be provided with a whole building ventilation system that ventilates a plurality of rooms (indoor spaces) by a common ventilation device. In the building 10 provided with these whole-building systems, all the glass doors 27 are closed when the system is operated because air conditioning and ventilation are performed while circulating air indoors.

Here, even in the building 10 provided with such a whole-building system, when the operation of the system is temporarily stopped, the glass door 27 is opened and the indoor ventilation is performed through the window 26. It is possible that it will be. For example, in a building 10 provided with an air conditioning system in the entire building, the operation of the system is stopped according to the climate in an intermediate period such as spring or autumn, and the glass door 27 is opened during the stop period to perform indoor ventilation. There are cases.

Therefore, it is conceivable to apply the notification system of the present invention to the building 10 provided with such a whole-building system to prevent the inflow of dust from the outside. In such a whole-building air conditioning / ventilation system, the system itself may be equipped with a dust sensor. For example, in an air-conditioning system in the entire building, an air conditioner (indoor unit) installed indoors has a suction port for sucking in surrounding (indoor) air, and the air-conditioned air is sucked from the indoor air sucked from the suction port. Generate. Then, the generated conditioned air is supplied to each room to perform air conditioning. In such a whole building air conditioning system, a dust sensor may be provided around the suction port, and in that case, it is conceivable to use the dust sensor for the notification system.

Further, in the whole building ventilation system, the ventilation device provided indoors has a suction port for sucking indoor air, and the indoor air sucked from the suction port is discharged to the outside by the ventilation device. .. Even in such a system, a dust sensor may be provided around the suction port, and in that case, it is conceivable to use the dust sensor for the notification system. As described above, by using the existing dust sensor in the system for the notification system, it is not necessary to newly install the dust sensor, and the effect of cost reduction and the like can be obtained.

Further, in the above-mentioned whole building type air conditioning system or ventilation system, a filter for removing dust is generally provided at the suction port of the air conditioner or the ventilation device. Therefore, in a building equipped with a whole-building air-conditioning system or ventilation system, when storing the amount of indoor dust as dust amount data, the system must be operated for a predetermined period in the fully closed state of each glass door 27. It is desirable to carry out the storage process of the dust amount data (step S39 in FIG. 6). In that case, even if dust flows from the outside to the inside of the window 26 when the glass door 27 is open, the dust amount data can be stored after the dust is removed by a filter to some extent and becomes stable. .. Therefore, it is possible to store the dust amount data in an amount close to the indoor dust amount, not including the outdoor inflow amount.

(10) The building 10 may be provided with an air purifier. In that case, the dust sensor built in the air purifier may be used as the dust sensor of the present notification system. In that case, since it is not necessary to newly provide a dust sensor because the built-in sensor is used, it is possible to obtain an effect such as cost reduction.

(11) By the way, when the amount of dust flowing from the outside to the inside of the building 10 through the window 26 (the amount of dust flowing outdoors) is large, the amount of dust scattered outdoors around the building 10 may be large. Conceivable. Therefore, it is considered that there is a high possibility that dust will flow from the outside to the inside through the window to other buildings in the vicinity of the building 10.

Therefore, in view of these points, a process of sending advice regarding opening / closing of windows to neighboring residents of the building 10 may be performed based on the amount of outdoor inflow dust calculated in step S23. Specifically, a notification device capable of wireless communication is provided in another building near the building 10, and the controller 50 provides advice information regarding opening and closing of windows from the communication unit 53 based on the calculated outdoor inflow dust amount of the neighboring building. It is conceivable to send it to the notification device. In this case, when the advice information is received by the notification device, the content of the advice information is notified by the notification device, for example, by voice. Therefore, neighboring residents can receive advice according to the amount of dust outdoors.

As an advice process, for example, when the amount of outdoor inflow dust calculated above is large, it is conceivable to give advice to neighboring residents to close the window. In this case, it is possible to prevent dust from flowing into the building of a neighboring resident from the outside. In addition, when the calculated amount of outdoor inflow dust is small, it is conceivable to give advice to neighboring residents to open windows. In this case, it is possible to encourage neighboring residents to stop air conditioning and ventilate the building.

In addition, window sensors that detect the opening and closing of windows are installed in each window of a neighboring resident's building, and it is determined whether or not all windows are closed based on the detection results of those window sensors, and all are closed. In the case where it is determined that the amount of dust inflowing outdoors is small, the neighbors may be advised to open the window.

In addition, when the advice processing to the neighboring residents is performed as described above, the resident of the building 10 can also receive a service charge from the neighboring residents.

(12) In the configuration of (11) above, the building 10 (for example, the outer wall) is provided with a temperature / humidity sensor for detecting outdoor temperature and humidity and an air volume sensor for detecting outdoor air volume, and each of these sensors detects the temperature and humidity. Advice processing to neighboring residents may be performed based on the outdoor temperature, humidity, and air volume. For example, it is conceivable to judge (evaluate) the comfort of the outside air based on the outdoor temperature, humidity, and air volume, and if the result of the judgment is that the outside air is comfortable, give advice to neighboring residents to open the window. Be done.
