Description

[Technical field]

[0001] The present disclosure relates to a notification technique, and more particularly to a program for notifying information and a computer that executes the program. [Background technology]

[0002] The purifying section of the air purifier is, for example, a filter made of a fiber or sponge-like material having a certain thickness and having numerous holes inside through which air can pass. The purifying section filters the air drawn in from the intake port by passing the air through the numerous holes. The filtered air is blown out from the air outlet to the outside of the air purifier (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-60584 A Summary of the Invention [Problem to be solved by the invention]

[0004] By connecting devices such as air purifiers to a network, the detection results of sensors installed in the devices are displayed on terminal devices such as smartphones. When multiple sensors are installed in one device, the detection results of each sensor are displayed separately. This makes it difficult for users to understand the detection results that have a large impact.

[0005] The present disclosure has been made in consideration of these circumstances, and has an object to provide a technology that improves the visibility of detection results from multiple sensors. [Means for solving the problem]

[0006] In order to solve the above problem, a program according to an embodiment of the present disclosure causes a computer to execute the steps of: acquiring air quality information including values ​​of a plurality of types of components from one or more devices; generating a single graph showing a time change for each component in the acquired air quality information; and outputting the single generated graph to an external device. In the acquiring step, values ​​of the multiple types of components included in the air quality information and indicated by different physical quantities are acquired, and in the generating step, the values ​​of the components indicated by different physical quantities are converted into a common unit, and then a single graph is generated showing the change over time for each component, and in the acquiring step, the different physical quantities for each component are acquired as dirt levels and converted into each level for each component, and in the generating step, the dirt levels acquired at a predetermined interval for each component are converted into the common unit of number of detections, and by accumulating the number of detections, an integrated value for a predetermined unit time that combines a plurality of the predetermined intervals is derived, and a single graph is generated showing the change over time of the integrated value, and in the conversion of the number of detections, if the dirt level acquired at the predetermined interval is 0, the number of detections is set to 0, and if the dirt level acquired at the predetermined interval is greater than 0, the number of detections is set to 1.

[0007] The problem is also solved by a computer that executes the program.

[0008] Another aspect of the present disclosure is also a program. The present invention provides a method for making a computer execute the steps of: acquiring air quality information including values ​​of a plurality of types of components from one or more devices; generating a single graph showing a time change for each component in the acquired air quality information; and outputting the single graph thus generated to an external device; and outputting the plurality of types of components included in the air quality information in the acquiring step and represented by different physical quantities. The values ​​of the components of the class are obtained, and the different physical quantities for each component are converted into levels for each component as dirt levels.The generating step accumulates the dirt levels obtained for each component at predetermined intervals to derive an accumulated value over a predetermined unit time that combines multiple predetermined intervals, and generates a graph that shows the time change of the accumulated value as the time change for each component.

[0009] The problem is also solved by a computer that executes the program.

[0010] Any combination of the above components, and conversion of the present disclosure into a method, device, system, recording medium, computer program, etc. are also valid aspects of the present disclosure. Effect of the Invention

[0013] Example 1 Before specifically describing the embodiments of the present disclosure, the knowledge on which the embodiments are based will be described. In recent years, by connecting devices to the Internet, device information is displayed on a terminal device such as a smartphone. For example, if the device is equipped with a gas sensor, gas information is displayed as dirt information on the terminal device. In addition, the history of time-varying gas information is displayed as a graph. Here, if the device is equipped with multiple types of sensors, a graph for each sensor is displayed separately. With such a display, it is difficult for the user to grasp the total amount of dirt that is a compilation of the detection results from multiple types of sensors, or the proportion of each type of dirt. Therefore, it is required to easily display the total amount and proportion of dirt at the same time.

[0014] 1(a)-(c) show the configuration of a notification system 1000. The notification system 1000 includes an air purifier 100, a ventilation fan 110, an air conditioner 120, a router 200, a network 300, a server 400, a terminal device 500, and a smart speaker 600. The air purifier 100, the ventilation fan 110, and the air conditioner 120 are collectively referred to as devices.

[0015] The air purifier 100 is a device having a removal function for removing dust, pollen, house dust, and the like suspended in the air. The air purifier 100 is equipped with, for example, a thermometer for measuring temperature, a hygrometer for measuring humidity, a particulate matter sensor for measuring the density of particulate matter such as PM2.5, a gas sensor for measuring the density of gas, and a dust sensor for measuring the density of dust. The thermometer, hygrometer, particulate matter sensor, gas sensor, and dust sensor are collectively referred to as sensors.

[0016] The exhaust fan 110 is a device that forcibly exhausts indoor air and smoke or replaces it with outdoor air (ventilation) by using a fan. The exhaust fan 110 is equipped with, for example, a thermometer for measuring temperature, a hygrometer for measuring humidity, and a CO2 sensor for measuring CO2 density. The thermometer, hygrometer, and CO2 sensor are also collectively referred to as sensors. The air conditioner 120 is one type of air conditioning equipment, and is a device that adjusts the temperature and humidity of indoor air. The air conditioner 120 is equipped with, for example, a thermometer for measuring temperature, and a hygrometer for measuring humidity. The thermometer and hygrometer are also collectively referred to as sensors. In this way, different types of sensors are equipped for each device.

[0017] The air purifier 100, the ventilator fan 110, and the air conditioner 120 have a communication function for wireless or wired communication, and can communicate with a router 200 installed in the facility in which they are installed. The router 200 communicates with a terminal device 500 and a smart speaker 600 in the facility, and also communicates with a network 300 outside the facility. The network 300 is, for example, the Internet, and is configured by wired communication, wireless communication, or a combination thereof. A server 400 is connected to the network 300.

[0018] With this configuration, the detection results of the sensors of the air purifier 100, the ventilation fan 110, and the air conditioner 120 can be confirmed on the terminal device 500 or the smart speaker 600. The terminal device 500 or the smart speaker 600 transmits a signal for requesting transmission of the detection results (hereinafter referred to as a "request signal") to the server 400 via the router 200 and the network 300. The server 400 transmits the request signal to the air purifier 100, the ventilation fan 110, and the air conditioner 120 via the network 300 and the router 200. The air purifier 100, the ventilation fan 110, and the air conditioner 120 transmit the detection results to the server 400 via the router 200 and the network 300. The server 400 transmits the detection results to the terminal device 500 and the smart speaker 600 via the network 300 and the router 200. The terminal device 500 and the smart speaker 600 display the detection results or output them as sound.

[0019] In the following, for clarity of explanation, it is assumed that the air purifier 100 transmits the detection result and the detection result is displayed on the terminal device 500. It is also assumed that the terminal device 500 displays the time variation of the detection result, that is, the history, as a graph. When the air purifier 100 is equipped with multiple types of sensors, it is required to easily display the total amount and percentage of dirt at the same time. Such processing is described in detail below.

[0020] 2(a)-(b) show the configuration of the server 400 and the terminal device 500. The server 400 in FIG. 2(a) includes a communication unit 410, a control unit 420, and a storage unit 430. The communication unit 410 receives the detection result from the air purifier 100 via the router 200 and the network 300. Here, the detection result from the air purifier 100 will be explained first. In the air purifier 100, the above-mentioned sensors detect the temperature, humidity, gas, dust, and PM2.5. The air purifier 100 holds the detected temperature and humidity values ​​as they are.

[0021] On the other hand, the air purifier 100 converts the gas detection value, dust detection value, and PM2.5 detection value into six dirt levels from 0 to 5. For example, the larger the detection value, the closer the dirt level is to "5". For such six-level evaluation, multiple thresholds are preset in the air purifier 100, and the detected value is compared with the multiple thresholds. Furthermore, the air purifier 100 indicates the pollen detection value in two dirt levels from 0 to 1. The dirt level "0" indicates that no pollen is detected, and the dirt level "1" indicates that pollen is detected. Although each detection value is indicated by a dirt level, it is a different physical quantity from each other. Such multiple types of detection values ​​correspond to the values ​​of multiple types of components included in the air quality information. Therefore, it can be said that the communication unit 410 receives air quality information from the air purifier 100. Here, the air quality information is a collective term for information on temperature, humidity, gas, dust (small and large), particulate matter (PM2.5), pollen, etc. in the air.

[0022] The communication unit 410 outputs the received detection result, that is, the air quality information including the values ​​of multiple types of components, to the control unit 420. The control unit 420 stores the air quality information in the storage unit 430 for a certain period of time. The control unit 420 generates a graph showing the time change of the air quality information based on the air quality information for the certain period stored in the storage unit 430. FIG. 3 shows an overview of the processing in the control unit 420. The horizontal axis indicates time, and the gas detection values ​​acquired at 10-minute intervals are arranged over one hour, for example, as "3", "4", "0", "2", "1", and "3". If the gas detection value is "1" or more, that is, if gas is detected, the control unit 420 converts the gas detection value to "1", and if the gas detection value is "0", it does not convert the gas detection value. In other words, the control unit 420 converts the gas detection value to "1" or "0" depending on whether or not gas is detected in the 10-minute interval. In the above example, the gas detection values ​​are ordered over the course of an hour, for example "1", "1", "0", "1", "1", "1".

[0023] The control unit 420 derives an integrated value of the gas detection values ​​for one hour (hereinafter referred to as the "integrated gas value") by adding up the detection values ​​of the multiple gases contained per hour. Such an integrated gas value indicates the number of times the gas is detected in 10-minute intervals in one hour. In the above example, the integrated gas value is "5." The control unit 420 performs such processing on the gas detection values ​​for other hours to obtain the time change in the integrated gas value for each hour. Return to FIG. 2(a).

[0024] The control unit 420 also executes the same process on the dust detection value and the PM2.5 detection value to obtain the time change of the gas integrated value in one-hour units and the time change of the PM2.5 integrated value in one-hour units. As a result, the gas detection value, dust detection value, and PM2.5 detection value, which are indicated by different physical quantities, are converted into the gas integrated value, dust integrated value, and PM2.5 integrated value, which have a common unit of the number of detections in 10-minute intervals. The control unit 420 generates one graph showing the time change of each component by overlapping the time change of the gas integrated value, the time change of the dust integrated value, and the time change of the PM2.5 integrated value while matching the corresponding times. The graph generated in this way will be described later.

[0025] Furthermore, if at least one of the pollen detection values ​​for 10 minutes included in one hour is "1", the control unit 420 sets the pollen integrated value for that hour to "1". On the other hand, if all of the pollen detection values ​​for 10 minutes included in one hour are "0", the control unit 420 sets the pollen integrated value for that hour to "0". The control unit 420 also includes the time change in the pollen integrated value in one graph. The communication unit 410 transmits the generated graph to the terminal device 500 via the network 300 and the router 200.

[0026] 2(b) includes a communication unit 510, a control unit 520, a display unit 530, and an operation unit 540. Communication unit 510 receives one graph from server 400. Communication unit 510 outputs one graph to control unit 520. Therefore, it can be said that control unit 520 acquires from server 400 one graph showing the time change of air quality information from air purifier 100 and showing the time change of each of the values ​​of multiple types of components included in the air quality information.

[0027] The control unit 520 displays a screen including the acquired graph on the display unit 530. FIG. 4 is a diagram showing a screen displayed on the display unit 530. A graph 900 is displayed in the center of the screen as "air pollution". The horizontal axis of the graph 900 indicates time. In addition, along the vertical axis of the graph 900, hourly changes in the integrated gas value 910, hourly changes in the integrated PM2.5 value 920, and hourly changes in the integrated dust value 930 are superimposed over 24 hours. Here, each component is shown in a different manner, for example, in a different color. In this way, a bar graph is formed by the hourly changes in the integrated gas value 910, the hourly changes in the integrated PM2.5 value 920, and the hourly changes in the integrated dust value 930. Additionally, at the top of the bar graph, hourly changes in the pollen count 940 are indicated by circles.

[0028] The operation unit 540 is an interface that accepts operations by the user. The operation unit 540 is, for example, a touch panel or buttons. When the operation unit 540 is a touch panel, the display unit 530 and the operation unit 540 are integrally configured.

[0029] Up to now, as described above, it has been assumed that the air purifier 100 in Fig. 1 transmits the detection result, but the ventilation fan 110 or the air conditioner 120 may transmit the detection result. The server 400 generates one graph 900 by performing the same process as before for the detection value of the sensor mounted on the ventilation fan 110 or the air conditioner 120, and the terminal device 500 displays one graph 900. In addition, the smart speaker 600 in Fig. 1 performs the same process as the terminal device 500, so a description thereof will be omitted here. At that time, the smart speaker 600 outputs audio instead of displaying on the terminal device 500.

[0030] The notification system 1000 in FIG. 1(b) includes a first base station device 310a and a second base station device 310b, which are collectively referred to as the base station device 310, in comparison with FIG. 1(a). A SIM (Subscriber Identity Module) card 320 can be inserted into the air purifier 100. The air purifier 100 connects to the first base station device 310a and communicates with the server 400 via the network 300. The terminal device 500 connects to the second base station device 310b and connects to the server 400 via the network 300. That is, the air purifier 100 and the terminal device 500 connect to the server 400 without going through the router 200. The notification system 1000 in FIG. 1(c) does not include the network 300 and the server 400 in comparison with FIG. 1(a). Therefore, the processing in the server 400 so far is executed in the terminal device 500 or the smart speaker 600.

[0031] The subject of the device, system, or method in the present disclosure includes a computer. The computer executes a program to realize the function of the subject of the device, system, or method in the present disclosure. The computer includes a processor that operates according to a program as a main hardware configuration. The type of the processor does not matter as long as it can realize the function by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). The multiple electronic circuits may be integrated into one chip or may be provided on multiple chips. The multiple chips may be integrated into one device or may be provided on multiple devices. The program is recorded on a non-transitory recording medium such as a computer-readable ROM, an optical disk, or a hard disk drive. The program may be stored in the recording medium in advance, or may be supplied to the recording medium via a wide area communication network including the Internet.

[0032] The operation of the notification system 1000 configured as above will be described. FIG. 5 is a sequence diagram showing a display procedure by the notification system 1000. The terminal device 500 transmits a request signal to the server 400 (S10). The server 400 transmits a request signal to the air purifier 100 (S12). The air purifier 100 transmits air quality information to the server 400 (S14). The server 400 generates a single graph 900 showing the time change of each component based on the air quality information (S16). The server 400 transmits the single graph 900 to the terminal device 500 (S18). The terminal device 500 displays a screen including the single graph 900 on the display unit 530 (S20).

[0033] According to this embodiment, when generating one graph 900 showing the time change of the air quality information, the time change of each of the multiple types of components included in the air quality information is shown, so that the visibility of the detection results of the multiple sensors can be improved. In addition, the values ​​of the components shown in different physical quantities are converted into a common unit before generating one graph 900 showing the time change of each component, so that the values ​​of the components shown in different physical quantities can be summarized. In addition, since each component is shown in a different manner in one graph 900, the visibility of the detection results of the multiple sensors can be improved. In addition, the total amount of dirt can be accumulated, and the proportion of each type can be expressed by color coding on one graph 900. In addition, the user can easily see the total amount and proportion of dirt at the same time, so that the dirt state in the room can be grasped in more detail.

[0034] An overview of one aspect of the present disclosure is as follows: A program according to one aspect of the present disclosure causes a computer to execute the steps of acquiring air quality information including values ​​of multiple types of components from one or more devices, generating a single graph 900 showing changes over time for each component in the acquired air quality information, and outputting the single generated graph 900 to an external device.

[0035] In the acquiring step, values ​​of the multiple types of components included in the air quality information and expressed as different physical quantities are acquired, and in the generating step, the values ​​of the components expressed as different physical quantities may be converted into a common unit, and then a single graph 900 showing the change over time for each component may be generated.

[0036] Another aspect of the present disclosure is also a program that causes a computer to execute a step of externally acquiring a single graph 900 showing time-varying changes in air quality information for each of a plurality of components from one or more devices, and a step of displaying the acquired single graph 900. In one graph 900, each component is shown in a different manner. Computers that execute the programs described herein are also within the scope of the present disclosure.

[0037] Example 2 Next, a second embodiment will be described. As with the first embodiment, the second embodiment relates to a notification system that displays the time change of the detection results of each of a plurality of sensors on a terminal device. When the number of devices connectable to a network increases, a plurality of devices may be installed in one space. Under such circumstances, when the information acquired from the devices is displayed for each device on the terminal device, the user must check and estimate the information of the plurality of devices in order to grasp the detection results of the space. Therefore, it is required to present the information of the space required by the user in a more understandable manner by collecting, calculating, and displaying the information of the devices on a space-by-space basis. The notification system 1000, server 400, and terminal device 500 according to the second embodiment are of the same type as those in FIG. 1 and FIG. 2(a)-(b). Here, the differences from the previous embodiments will be mainly described.

[0038] FIG. 6 shows the configuration of a room in which the notification system 1000 is installed. The facility is, for example, a house, and includes multiple rooms. Each of the multiple rooms includes, for example, a living room 700, a bedroom 710, a dining room 720, and a Japanese-style room 730. The living room 700, the bedroom 710, the dining room 720, and the Japanese-style room 730 can be said to be one space independent of each other. The living room 700 is installed with a first air purifier 100a and a second air purifier 100b, and the bedroom 710 is installed with a third air purifier 100c, a first ventilation fan 110a, and an air conditioner 120. The dining room 720 is installed with a fourth air purifier 100d, and the Japanese-style room 730 is installed with a fifth air purifier 100e and a second ventilation fan 110b. The first air purifier 100a, the second air purifier 100b, the third air purifier 100c, the fourth air purifier 100d, and the fifth air purifier 100e are collectively referred to as air purifier 100, and the first ventilation fan 110a and the second ventilation fan 110b are collectively referred to as ventilation fan 110. Here, a plurality of devices equipped with the same sensor are installed in the living room 700, and a plurality of devices equipped with different sensors are installed in the bedroom 710 and the Japanese-style room 730.

[0039] 7(a)-(b) show information in the notification system 1000. FIG. 7(a) shows the detection results of the first air purifier 100a and the second air purifier 100b installed in the living room 700 of FIG. 2. The temperature and humidity values ​​detected by the first air purifier 100a are shown as they are. Furthermore, the gas detection value, small dust detection value, large dust detection value, and PM2.5 detection value of the first air purifier 100a are each shown with six levels of dirtiness from 0 to 5. Furthermore, the pollen detection value of the first air purifier 100a is shown with two levels of dirtiness from 0 to 1. FIG. 7(b) will be described later.

[0040] The detection results of each of the multiple devices such as the air purifier 100, the ventilation fan 110, and the air conditioner 120 in Fig. 1 and Fig. 6 are transmitted to the server 400 via the router 200 and the network 300 in Fig. 1. Here, each detection result includes identification information "ID" for identifying the device that is the transmission source. Therefore, it can be said that the control unit 420 acquires the detection results of each of the multiple devices from each of the multiple devices. The control unit 420 stores the detection results in the storage unit 430 based on the ID included in the detection results.

[0041] The storage unit 430 stores the detection results for each ID. The storage unit 430 also stores the correspondence between the ID and the identification information of the space in which the device with the ID is installed (hereinafter referred to as "space ID"). For example, the living room 700 in FIG. 6 is assigned the space ID "1", the bedroom 710 is assigned the space ID "2", the dining room 720 is assigned the space ID "3", and the Japanese-style room 730 is assigned the space ID "4". Based on the correspondence stored in the storage unit 430, the control unit 420 organizes the detection results of each device stored in the storage unit 430 as detection results for each space ID. This corresponds to organizing the detection results of each device into detection results for each room, that is, for each same space.

[0042] For example, the detection results for space ID "1" are the detection results of sensors mounted on the first air purifier 100a and the second air purifier 100b arranged in the living room 700. Therefore, these detection results are the detection values ​​of temperature, humidity, gas, dust (small and large), particulate matter (PM2.5), and pollen. In other words, values ​​of multiple types of components are acquired. The control unit 420 derives air quality information that is a compilation of detection results from two or more devices arranged in the same space and that includes values ​​of multiple types of components. To be more specific, the control unit 420 performs statistical processing for each component on the detection results from two or more devices arranged in the same space.

[0043] When the temperature in the first air purifier 100a indicates 22°C and the temperature in the second air purifier 100b indicates 24°C, the control unit 420 averages these temperatures to derive the temperature "23°C" of the living room 700. The control unit 420 also performs averaging processing on the humidity in the same manner as for the temperature. The control unit 420 also compares the gas detection value in the first air purifier 100a with the gas detection value in the second air purifier 100b to select the maximum value. For example, when the gas detection value in the first air purifier 100a indicates a dirt level "1" and the gas detection value in the second air purifier 100b indicates a dirt level "3," the gas detection value in the living room 700 is determined to be the dirt level "3." The control unit 420 also performs processing on the detection values ​​of dust (small and large), particulate matter (PM2.5), and pollen in the same manner as for the gas detection value. Here, control unit 420 may use any of the minimum, maximum, and average values ​​for each component. Such processing is shown in Fig. 7(b). As a result, control unit 420 generates information on the air quality in living room 700, which includes multiple types of components such as temperature, humidity, gas detection values, dust (small and large) detection values, particulate matter (PM2.5) detection values, and pollen detection values.

[0044] Moreover, the detection results for the space ID "2" are the detection results of the sensors mounted on the third air purifier 100c, the first ventilation fan 110a, and the air conditioner 120 arranged in the bedroom 710. Therefore, these detection results are the temperature, humidity, gas detection values, dust (small, large) detection values, particulate matter (PM2.5) detection values, pollen detection values, and CO2 detection values. Here, the CO2 detection value is output only from the first ventilation fan 110a, and the gas detection value, dust (small, large) detection value, particulate matter (PM2.5) detection value, and pollen detection value are output only from the third air purifier 100c. Therefore, the control unit 420 regards the CO2 detection value from the first ventilation fan 110a as the CO2 detection value in the bedroom 710. Furthermore, control unit 420 regards the gas detection values, dust detection values ​​(small and large), particulate matter (PM2.5), and pollen detection values ​​from third air purifier 100c as those detection values ​​in bedroom 710. The same processing as that in living room 700 is performed for temperature and humidity. As a result, control unit 420 generates information on the air quality in bedroom 710, which includes multiple types of components such as temperature, humidity, gas detection values, dust detection values ​​(small and large), particulate matter (PM2.5), pollen detection values, and CO2 detection values.

[0045] The control unit 420 executes similar processing for the dining room 720 with space ID "3" and the Japanese-style room 730 with space ID "4". For the air quality information generated in this manner, the control unit 420 executes processing similar to that of the first embodiment to generate one graph 900. In other words, the control unit 420 organizes the air quality information obtained from each of the multiple devices by component, and then generates one graph 900 showing the change over time for each component.

[0046] According to this embodiment, the air quality information is derived by combining the detection results from two or more devices among a plurality of devices arranged in the same space, and includes values ​​of a plurality of types of components, so that the air quality in one space can be notified. Also, the detection results from two or more devices arranged in the same space are subjected to statistical processing for each component to derive the air quality information, so that the accuracy of the derived air quality can be improved. Also, the maximum value is selected as the statistical processing, so that the worst air quality can be notified.

[0047] An overview of one aspect of the present disclosure is as follows: The acquiring step may acquire air quality information from each of a plurality of devices arranged in the same space, and the generating step may aggregate the air quality information acquired from each of the plurality of devices for each component, and then generate one graph 900 showing the change over time for each component.

[0048] Computers that execute the programs described herein are also within the scope of the present disclosure.

[0049] The present disclosure has been described above based on the embodiments. These embodiments are merely illustrative, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each treatment process, and that such modifications are also within the scope of the present disclosure.

[0050] In the first and second embodiments, one graph 900 is shown as a bar graph. However, the present invention is not limited to this, and may be, for example, a colored line graph. According to this modification, the degree of freedom of configuration can be improved.

[0051] In the first and second embodiments, the control unit 420 converts the detection values ​​to "1" or "0" depending on whether gas or the like is detected at 10-minute intervals, and then adds these values ​​over one hour to derive the integrated value. However, this is not a limitation, and for example, the control unit 420 may derive the integrated value by adding the detection values ​​at 10-minute intervals as they are over one hour. This modification improves the flexibility of the configuration. [Explanation of symbols]
