According to such a configuration, the operator of the server device 100 can know the relationship between the contamination status and the contamination location.

Hereinafter, a method of using the detection result acquired by the server device 100 will be described.
(C2. Notification and notification)
The server device 100 refers to the data table D4 and executes one of the following processes.

(1) First Processing Example The server device 100 identifies an air purifier 200 in which the degree of air pollution exceeds a predetermined standard from among a plurality of air purifiers 200. Specifically, the server device 100 refers to the data table D4, and among the plurality of air purifiers 200, the air purifier 200 whose odor concentration (value) is equal to or higher than the reference value, and the dust. The air purifier 200 whose concentration (value) is equal to or higher than the reference value is specified. The odor reference value and the dust reference value are typically set individually.

The server device 100 causes the specified air purifier 200 to execute a predetermined notification. Specifically, when the server device 100 transmits a predetermined command to the specified air purifier 200, the server device 100 causes the air purifier 200 to output by voice that the air is particularly dirty. .. Further, the server device 100 may output the content of the proposal for filter replacement from the air purifier 200 by voice.

By causing the air purifier 200 to execute such a notification, the user of the specified air purifier 200 can visually recognize that the air in a building such as a home is particularly dirty by displaying the operation panel 211. It can be recognized more clearly than. In addition, the content by the above-mentioned voice may be displayed on the operation panel 211 instead of the voice.

In addition, the above-mentioned "predetermined standard" may be set for each region. For example, the standard may be set higher in urban areas and lower in suburbs such as rural areas. According to such a configuration, processing in consideration of the characteristics of the region becomes possible. The server device 100 determines to which area the air purifier 200 belongs based on the position information.

(2) Second Processing Example The server device 100 uses a smartphone or the like registered in advance by the user of the specified air purifier 200 instead of causing the specified air purifier 200 to execute a predetermined notification. Sends a predetermined notification (typically a message) to the electronic device. Specifically, the server device 100 sends an e-mail to the electronic device for notifying the user that the air is particularly dirty. Further, the server device 100 may send an e-mail containing the content proposing the filter replacement to the air purifier 200.

By giving such a notification to the electronic device, the specified user of the air purifier 200 recognizes that the air in the building such as a home is particularly dirty by means other than the air purifier 200. be able to. The server device 100 may perform the first processing example together with the second processing example.

(3) Third Processing Example The server device 100 specifies a predetermined number of air purifiers 200 installed in the same area in order of increasing degree of air pollution.

When the server device 100 identifies the air purifier 200 in this way, the server device 100 causes the air purifier 200 to execute a predetermined notification as described in the first processing example. Further, as described in the second processing example, a predetermined notification is transmitted to an electronic device such as a smartphone registered in advance by the specified user of the air purifier 200. , The server device 100 may be configured. Further, in the case of this configuration, it may be notified or notified that the air in the room (indoor) is dirty as compared with the air in the neighboring building.

According to such a configuration, it is possible to call attention or make a proposal to a user of the air purifier 200 who lives in a building in the same area where the indoor air is particularly dirty.

(C3. Creating and using maps)
In addition to the above-mentioned notification or notification, the server device 100 refers to the data table D4 to create a pollution map showing the indoor air pollution status and a pollution map showing the outdoor air pollution status. create.

(1) Creation of a pollution map showing the pollution status of indoor air The server device 100 uses the detection result of the odor sensor 212 and the detection result of the dust sensor 213 of each air purifier 200, the position information of the data table D4, and the position information of the data table D4. Based on the map data D5 (see FIG. 6) stored in advance, a map showing the degree of contamination (contamination status) of each door (by building) is created. The map data D5 is data for individually classifying and displaying buildings such as houses. As the map data D5, for example, residential map data can be used.

Specifically, the server device 100 includes an odor pollution map using the detection result by the odor sensor 212, a dust pollution map using the detection result by the dust sensor 213, and a detection result by the odor sensor 212 and a detection result by the dust sensor 213. Create an odor and dust pollution map using.

(I) Odor pollution map When creating the odor pollution map, the server device 100 changes the display mode of the figure representing the building on the map to the display mode according to the pollution level indicated by the detection result by the odor sensor 212. ..

For example, when the detection result represents a strong odor, the server device 100 displays the building in which the air purifier 200 that has detected such a result is installed in the first aspect (for example, red). .. Further, when the detection result shows a moderate odor, the server device 100 sets the building in which the air purifier 200 that has detected such a result is installed in the second aspect (for example, yellow). indicate. When the detection result represents a weak odor, the server device 100 displays the building in which the air purifier 200 that has detected such a result is installed in a third mode (for example, green). ..

The server device 100 leaves the default state (typically, white) for the building for which the detection result by the odor sensor 212 has not been obtained.

According to such an odor pollution map, it is possible to easily visually determine which building interior is contaminated by odor.

(Ii) Dust pollution map When creating a dust pollution map, the dust pollution map server device 100 changes the display mode of a figure representing a building on the map to a display mode according to the pollution level indicated by the detection result by the dust sensor 213. ..

FIG. 5 is a diagram showing an example of a dust pollution map. With reference to FIG. 5, the server device 100 displays the building in which the air purifier 200 that has detected a large amount of dust is installed in the first aspect (hatching of a thick line in the case of FIG. 5). Further, the server device 100 displays the building in which the air purifier 200 that has detected a medium amount of dust is installed in the second aspect (in the case of FIG. 5, hatching of thin lines). Further, the server device 100 displays the building in which the air purifier 200 that has detected a small amount of dust is installed in a third aspect (in the case of FIG. 5, hatching of fine lines with wide intervals).

According to such a dust pollution map, it is possible to easily visually determine which building interior is contaminated with dust.

(Iii) Odor and Dust Contamination Map When creating an odor and dust contamination map, the server device 100 displays the display mode of a figure representing a building on the map with the pollution level indicated by the detection result by the odor sensor 212 and the dust sensor 213. The display mode will be changed to take into consideration the two levels of contamination indicated by the detection result. For example, when the server device 100 classifies each of the pollution level due to odor and the pollution level due to dust into three stages, the pollution level is classified into six stages by summing each pollution level. The server device 100 changes the display mode of the figure representing the building on the map to the display mode according to the six levels.

According to such a dust pollution map, it is possible to easily visually determine which building's interior is contaminated.

(2) Pollution map showing the pollution status of outdoor air The detection result of the air purifier 200 is affected by the outside air. For example, when a window is opened for ventilation, pollutants in the outside air enter the room. In addition, pollutants in the outside air can enter the room by opening and closing the front door.

Therefore, the detection result of the air purifier 200 may correlate with the pollution of the outside air. In particular, by using the detection results of a plurality of air purifiers 200 in the same area, it is possible to determine the state of pollution of the outside air.

Therefore, the server device 100 creates a pollution map (hereinafter, also referred to as “air pollution map”) showing the degree of pollution (pollution status) of the outdoor air with reference to the data table D4. For example, the server device 100 applies a color scheme according to the pollution level to the entire map displayed based on the map data D5.

When determining the outdoor pollution level in a certain area, the server device, for example, detects a plurality of detection results by a plurality of air purifiers 200 installed in the area, excluding a peculiar detection result. The average of the results can be used.

The area also includes an area smaller than a municipality or ward (for example, a chome). Further, when the number of data obtained in one area is small, the server device 100 may be configured so as to set an area larger than the area as one area.

According to the server device 100, it is possible to create an air pollution map by using the detection result of the air purifier 200.

Further, when the server device 100 further uses the altitude information of GPS as described above, the server device 100 can also create an air pollution map for each altitude.

(3) Other methods of using the pollution map In order for the user of the air purifier 200 to utilize the created pollution map (odor pollution map, dust pollution map, odor and dust pollution map, air pollution map), the server device 100 May transmit a pollution map to an electronic device such as a smartphone 300 owned by the user.

In addition, the created pollution map may be provided (for example, sold) to a third party so that the third party can utilize it. Such provision can be performed, for example, by the server device 100 transmitting pollution map data to an information processing device such as a personal computer owned by a third party.

In particular, by providing odor pollution maps, dust pollution maps, and / or odor and dust pollution maps to the cleaning contractors who are undertaking the cleaning of the building, the cleaning companies shall use these maps for their business activities. Can be done.

Also, in the odor pollution map, the dust pollution map, and / or the odor and dust pollution map, if the pollution state of the building does not change for a long period of time, it is assumed that humans are not active. Therefore, the safety of the elderly and the like can be confirmed by using such a map by the local government and the like. When the server device 100 automatically performs such safety detection, the map display is not always necessary.

(C4. Other uses of detection results)
If the concentrations of carbon monoxide and carbon dioxide obtained by the odor sensor 212 are equal to or higher than the reference values, it is considered that a fire has occurred. It is also considered that a fire has occurred when the detection result by the temperature sensor (shown) is equal to or higher than the reference temperature.

Therefore, the server device 100 detects the occurrence of a fire based on the detection result of at least one of these sensors.

[Embodiment 2]
In the present embodiment, the server device 100 creates an air pollution map after a predetermined time in addition to the four pollution maps described above.

FIG. 8 is a diagram showing a schematic configuration of the information system 1A according to the present embodiment. With reference to FIG. 8, the information system 1A is different from the information system 1 (FIG. 1) according to the first embodiment in that the information system 1A further includes a server device 500 communicably connected to the server device 100.

The server device 500 is a device operated by the Japan Meteorological Agency or a meteorological company. The server device 500 stores weather information from all over the country.

The server device 100 acquires wind information for each region from the server device 500. Specifically, the server device 100 acquires information on the wind speed and the wind direction. Based on the wind information and the detection results by the odor sensor 212 and the dust sensor, the server device 100 further creates a prediction map showing the outdoor air pollution status after a predetermined time has elapsed. .. For example, the server device 100 creates a prediction map after one hour for each region.

The server device 100 typically transmits a prediction map of the area where the air purifier is installed to each smartphone 400. The server device 100 may transmit the prediction map to a cleaning company or the like.

According to such a configuration, the user of each air purifier 200 can know in advance the state of pollution of the outside air after a predetermined time has elapsed. Therefore, when it is predicted that the pollution will be severe, the user will take proactive measures such as changing the operation mode of the air purifier 200 to a mode in which the cleaning function is strengthened or refraining from opening and closing the window. be able to.

[Embodiment 3]
In the present embodiment, the server device 100 searches for a building in which the indoor air is locally polluted by using the degree of pollution of the indoor (indoor) air and the degree of pollution of the outdoor air (outside air).

For example, the server device 100 compares the detection results of the odor sensor 212 and the dust sensor 213 shown in the above-mentioned data table D4 with the degree of pollution of the outdoor air (outside air). Specifically, the server device 100 acquires the measurement result from the server device that stores the measurement result of air pollution in each area, and the detection result is a reference value rather than the measurement result from the plurality of air purifiers 200. Identify the higher air purifier 200.

The reason for making such a comparison is that the degree of pollution of the outside air differs depending on the region. For example, in urban areas and suburbs, the degree of pollution of the outside air is higher in urban areas. In order to consider such local circumstances, the server device 100 utilizes the degree of pollution of the outside air.

In the present embodiment, instead of the server device 500, an air pollutant wide area monitoring system operated by the national government (Ministry of the Environment) can be used. Specifically, the server device 100 acquires information indicating the degree of pollution of the outdoor air (outside air) in each region from the server device of the air pollutant wide area monitoring system.

The server device 100 identifies the position of the building where the indoor air is more polluted than the outside air by the reference value or more by using the position information of the air purifier 200. If you are operating the air purifier 200, the indoor air should normally be cleaner than the outside air. Nevertheless, the reason why the indoor air is more polluted than the outside air is that the filter of the air purifier 200 is deteriorated, or the indoor air is not properly cleaned.

Therefore, it is possible to develop various businesses by using the information of the locally polluted building. For example, such information can be sold to cleaners. In addition, the manufacturer of the air purifier 200 can urge the user to replace the filter. For example, the server device 100 can send an e-mail suggesting replacement of the filter to the user's smartphone 400 or the like. Alternatively, the server device 100 sends a command to the air purifier 200 installed in the locally dirty room to output a sound prompting the filter replacement from the speaker 214 of the air purifier 200. With such a configuration, it is possible to keep the air in the room clean.

[Embodiment 4]
In this embodiment, a configuration that does not use the air pollutant wide area monitoring system shown in the third embodiment will be described.

FIG. 9 is a diagram showing a schematic configuration of the information system 1B according to the present embodiment. With reference to FIG. 9, the information system 1B is different from the information system 1 according to the first embodiment in that it further includes a plurality of air conditioners 600a, 600b, 600c, 600d, ....

The air conditioner 600a is installed in the same building as the air purifier 200a. The air conditioner 600a includes an indoor unit 601a and an outdoor unit 602a. The outdoor unit 602a is provided with an odor sensor and a dust sensor. That is, the odor sensor and the dust sensor are installed inside and outside the room where the air purifier 200 is provided.

The odor sensor detects the concentration of gas (particles) that causes pollution of the outside air. The dust sensor detects the concentration of dust by detecting the amount of dust that causes the outside air to become dirty. The detection result by the odor sensor and the detection result by the dust sensor are periodically transmitted to the server device 100 via the indoor unit 601a and the wireless router 300a. When the transmission cycle Td of the detection result of the air purifier 200 is long, it is preferable that the transmission of the detection result by the outdoor unit 602a and the transmission of the detection result of the air purifier 200 are synchronized.

The air conditioner 600b includes an indoor unit 601b and an outdoor unit 602b. The air conditioner 600c includes an indoor unit 601c and an outdoor unit 602c. The air conditioner 600d includes an indoor unit 601d and an outdoor unit 602d. The outdoor units 602b, 602c, and 602d are provided with an odor sensor and a dust sensor like the outdoor unit 602a, and transmit a detection result to the server device 100 like the outdoor unit 602a.

The server device 100 uses the detection results acquired from the outdoor units 602a, 602b, 602c, 602d, ... As the measurement results of air pollution in each region. As a result, the server device 100 does not need to acquire information indicating the degree of pollution of the outdoor air (outside air) in each place from the server device of the air pollutant wide area monitoring system.

Even with such a configuration, the same effect as that of the third embodiment can be obtained.
