DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0026] 1 is a block diagram showing an example of a determination system 200 according to an embodiment of the present invention. The determination system 200 includes a determination device 100 and a mobile terminal 300. The mobile terminal 300 has a CO2 (carbon dioxide) sensor 400. The mobile terminal 300 is, for example, a smartphone, a tablet, an HMD (Head Mounted Display), or a wearable device. A wearable device refers to a computer that is attached to a part of the body, such as an arm, a leg, or a head. An example of a wearable device is a smart watch.

[0027] The CO2 (carbon dioxide) sensor 400 measures the CO2 (carbon dioxide) concentration in a determination target 500. The determination target 500 is an object that is the subject of a determination regarding the CO2 (carbon dioxide) concentration. The object is, for example, an indoor room. The object may also be a specified space outdoors. The CO2 (carbon dioxide) sensor 400 measures the concentration of CO2 (carbon dioxide) 510 contained in the air present in the object.

[0028] When the object to be determined 500 is an indoor room, the mobile terminal 300 may be placed inside the room. When the object to be determined 500 is an indoor room, the determination device 100 may be placed inside the room or outside the room.

[0029] In this example, the mobile terminal 300 includes a wireless transmission unit 310. In this example, the wireless transmission unit 310 transmits the concentration of CO2 (carbon dioxide) 510 measured by the CO2 (carbon dioxide) sensor 400 to the determination device 100.

[0030] The determination device 100 includes a determination unit 10. The determination unit 10 determines the state of the CO2 (carbon dioxide) concentration in the determination object 500 and the measurement state of the CO2 (carbon dioxide) concentration in the determination object 500 based on the CO2 (carbon dioxide) concentration in the determination object 500. In this example, the CO2 (carbon dioxide) concentration in the determination object 500 is transmitted by the wireless transmission unit 310.

[0031] The determination unit 10 may be a CPU (Central Processing Unit). The determination device 100 may be a computer including the CPU, a memory, an interface, etc. The determination device 100 may be a portable computer such as a tablet.

[0032] The status of the CO2 (carbon dioxide) concentration in the determination object 500 is referred to as a status Sd. The measurement status of the CO2 (carbon dioxide) concentration in the determination object 500 is referred to as a measurement status Sm. The status Sd refers to at least one of the level of concentration and the level of concentration change of CO2 (carbon dioxide) 510 in the determination object 500. The status Sd refers to, for example, whether the CO2 (carbon dioxide) concentration in the determination object 500 is an abnormal value, a normal value close to an abnormal value, or is rapidly approaching an abnormal value.

[0033] The measurement situation Sm refers to a situation related to the measurement environment of the concentration of CO2 (carbon dioxide) 510 in the determination target 500. The measurement situation Sm refers to a situation in which the concentration of CO2 (carbon dioxide) 510 in the determination target 500 is measured, for example, in a situation where the CO2 (carbon dioxide) sensor 400 is in contact with human breath, in a situation where the CO2 (carbon dioxide) sensor 400 is placed in a position close to a wall, or in which the mobile terminal 300 having the CO2 (carbon dioxide) sensor 400 is moving.

[0034] The determination unit 10 may output a determination result between the situation Sd and the measurement situation Sm. The determination result is set as a determination result Rd. This allows the user of the determination device 100 to know the concentration situation Sd of the CO2 (carbon dioxide) 510 in the determination target 500 and the measurement situation Sm.

[0035] The determination unit 10 may determine the state Sd of the concentration of CO2 (carbon dioxide) 510 based on the time change of the concentration of CO2 (carbon dioxide) 510. By determining the state Sd based on the time change of the concentration of CO2 (carbon dioxide) 510, the user of the determination device 100 can know the state Sd determined based on the time change of the concentration of CO2 (carbon dioxide) 510 and the measurement state Sm of the concentration of CO2 (carbon dioxide) 510. When the concentration of CO2 (carbon dioxide) 510 increases with time change, the determination unit 10 may determine that the state Sd is in an abnormal state even if the concentration of CO2 (carbon dioxide) 510 is less than a certain reference value. The time change of the concentration of CO2 (carbon dioxide) 510 may include a time differential value, a time integral value, a statistical distribution, a statistical amount, a time average value, a variance per time, a deviation amount from the average value per time, and a predicted value after a certain time predicted from the time change.

[0036] 2 is a block diagram showing another example of a determination system 200 according to an embodiment of the present invention. In this example, the determination device 100 further includes a control unit 20, a notification unit 30, and a position information acquisition unit 40. The determination system 200 of this example differs from the determination system 200 shown in FIG. 1 in this respect.

[0037] The notification unit 30 notifies the determination result Rd by the determination unit 10. The notification unit 30 may notify the determination result Rd in a form that can be recognized by human vision. The notification unit 30 is, for example, a display, a monitor, etc. The position information acquisition unit 40 acquires position information of the determination target 500. The position information acquisition unit 40 is, for example, a GPS (Global Positioning System). When the determination device 100 is a portable computer such as a tablet, the notification unit 30 may be a display of the computer, and the position information acquisition unit 40 may be a GPS provided in the computer. The position information acquisition unit 40 may acquire position information of the determination device 100.

[0038] The control unit 20 controls whether to notify the notification unit 30 of the judgment result Rd by the judgment unit 10 based on the position information of the judgment target 500 acquired by the position information acquisition unit 40. The control unit 20 may control whether to notify the notification unit 30 of the judgment result Rd. The control unit 20 may be a CPU (Central Processing Unit). The judgment unit 10 and the control unit 20 may be one CPU.

[0039] For example, when the location information of the determination target 500 acquired by the location information acquisition unit 40 is in the vicinity of a factory that burns fossil fuels, the concentration of CO2 (carbon dioxide) 510 may be constantly higher in the vicinity of the factory than in other areas. In such a case where the situation Sd of the CO2 (carbon dioxide) concentration is predicted in advance and no action is required for the situation Sd, the control unit 20 does not need to notify the notification unit 30 of the determination result Rd by the determination unit 10.

[0040] The determination unit 10 may determine a measurement situation Sm of the concentration of CO2 (carbon dioxide) 510 in the determination object 500 based on the position information of the determination object 500 acquired by the position information acquisition unit 40. The determination unit 10 may determine the measurement situation Sm based on the concentration of CO2 (carbon dioxide) 510 and the position information of the determination object 500. The determination unit 10 may determine the measurement situation Sm based on the position information of the determination object 500, not based on the concentration of CO2 (carbon dioxide) 510.

[0041] Fig. 3 is a block diagram showing another example of a determination system 200 according to an embodiment of the present invention. In this example, the determination device 100 further includes an information acquisition unit 42. The determination system 200 of this example differs from the determination system 200 shown in Fig. 2 in this respect. The information acquisition unit 42 acquires improvement information corresponding to at least one of the carbon dioxide concentration status Sd and the carbon dioxide concentration measurement status Sm. The improvement information is referred to as improvement information Si.

[0042] In this example, the improvement information Si according to the situation Sd refers to advertisement information or the like of a company that can improve or eliminate the cause of the situation Sd. For example, when the situation Sd is a situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value, a company that can improve or eliminate the cause is a ventilation company that can eliminate the abnormal value. For example, when the situation Sd is a situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value, the improvement information Si may include improvement information, maintenance information, etc. for eliminating the abnormal value.

[0043] In this example, the improvement information Si according to the measurement situation Sm refers to advertisement information of a company that can improve the measurement situation Sm. For example, when the measurement situation Sm is a situation in which the CO2 (carbon dioxide) sensor 400 is measured in an insufficiently calibrated state, a company that can improve the measurement situation Sm is a calibration company that can resolve the insufficient calibration state.

[0044] In this example, the control unit 20 controls the notification unit 30 to notify the determination result Rd by the determination unit 10 and the improvement information Si based on the location information of the determination target 500. For this reason, when the situation Sd is, for example, a situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value, the control unit 20 can cause the notification unit 30 to notify advertisement information, etc. of one or more businesses that are close to the location of the determination target 500 and can resolve the situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value. This allows the user of the determination device 100 to know the businesses that can resolve the situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value. When the notification unit 30 is caused to notify the determination result Rd and the improvement information Si, the notification unit 30 may notify multiple businesses. The order in which the multiple businesses are notified or the size of the notification may be prioritized. For example, the order in which the above-mentioned businesses are notified may be changed for each carbon dioxide concentration range, and a specific business may be notified preferentially at the top.

[0045] The control unit 20 may change the judgment result Rd and the improvement information Si to be notified by the notification unit 30 based on the position information of the judgment target 500. The control unit 20 may control the notification unit 30 to notify the changed judgment result Rd and the improvement information Si to the notification unit 30. When the judgment device 100 is, for example, a portable tablet or the like, the position information of the judgment device 100 changes with the movement of the judgment device 100. For this reason, for example, a company that can resolve a situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value and is close to the current location of the judgment target 500 may change with the movement of the judgment device 100. When the company close to the current location of the judgment target 500 changes with the movement of the judgment device 100, the control unit 20 may change the judgment result Rd and the improvement information Si to be notified by the notification unit 30 according to the position information of the judgment target 500.

[0046] FIG. 4 is a block diagram showing another example of a determination system 200 according to an embodiment of the present invention. In this example, the determination device 100 includes an audio output unit 32 instead of the notification unit 30. The determination system 200 of this example differs from the determination system 200 shown in FIG. 3 in this respect. The audio output unit 32 outputs audio related to the determination result Rd by the determination unit 10. The audio output unit 32 may output the determination result Rd in a form that can be recognized by human hearing. The audio output unit 32 is, for example, a speaker. The notification unit 30 may be a light notification unit that notifies by light or a vibration notification unit that notifies by vibration.

[0047] In this example, the control unit 20 controls the audio output unit 32 to output audio related to the judgment result Rd by the judgment unit 10 and the improvement information Si based on the position information of the judgment target 500. The audio related to the judgment result Rd and the improvement information Si is, for example, the name of a company that can resolve the situation where the concentration of CO2 (carbon dioxide) 510 is an abnormal value.

[0048] Fig. 5 is a block diagram showing another example of the determination system 200 according to an embodiment of the present invention. In Fig. 5, the determination target 500 and the mobile terminal 300 shown in Figs. 2 to 4 are omitted. In this example, the determination device 100 further includes a transmission unit 50. The determination system 200 of this example differs from the determination system 200 shown in Fig. 3 in this respect. The transmission unit 50 transmits the determination result Rd and the improvement information Si. The transmission unit 50 may transmit the determination result Rd and the improvement information Si wirelessly.

[0049] The information acquisition unit 42 may further acquire destination information regarding a destination to which the judgment result Rd and the improvement information Si are transmitted. The destination is referred to as the destination 52. The destination information is referred to as the destination information Is. The destination 52 may be at least one of a company capable of eliminating the cause of the CO2 (carbon dioxide) concentration status Sd in the judgment target 500 and a company capable of improving the measurement status Sm of the CO2 (carbon dioxide) concentration in the judgment target 500.

[0050] The information acquisition unit 42 may acquire destination information Is related to multiple destinations 52. The information acquisition unit 42 may acquire the destination information Is via an Internet line. In this example, the information acquisition unit 42 acquires destination information Is related to at least one of the five destinations 52 (destination 52-1 to destination 52-5). The information acquisition unit 42 may acquire the destination information Is wirelessly. In FIG. 5, the acquisition path of the destination information Is is indicated by a thick dashed arrow.

[0051] In this example, destination 52-1 is a ventilation equipment business, destination 52-2 is a calibration equipment business, destination 52-3 is a cleaning company, destination 52-4 is a fire station, and destination 52-5 is an e-commerce business. The ventilation equipment business is, for example, a manufacturer of air conditioning equipment (air conditioners). If the determination target 500 is an indoor room, the cleaning company is, for example, a company that cleans ducts that exhaust indoor air to the outdoors. The e-commerce business is, for example, a business that sells products via the Internet. These destinations are just examples. Destination 52 is, for example, an air conditioning equipment manufacturer. quality The application may be a company that operates an application such as management, or may be an insurance company.

[0052] The control unit 20 may control the transmission unit 50 to transmit the judgment result Rd and the improvement information Si to the transmission destination 52 based on the location information of the judgment target 500. The judgment result Rd and the improvement information Si may be transmitted to the transmission destination 52 via an Internet line. In Fig. 5, the transmission path of the judgment result Rd and the improvement information Si is indicated by a thick dashed line arrow.

[0053] In this example, the judgment result Rd and the improvement information Si are transmitted based on the position information of the judgment target 500. Therefore, when the situation Sd is, for example, a situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value, the control unit 20 can control the transmission unit 50 to transmit the judgment result Rd and the improvement information Si to a company that can resolve the situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value and is closest to the current position of the judgment target 500. This allows the closest company to arrive at the judgment target 500 more quickly than a company that is farther from the current position of the judgment target than the closest company.

[0054] The control unit 20 may control the transmission unit 50 to transmit the determination result Rd and the improvement information Si to the transmission destination 52 based on the determination result Rd, the improvement information Si, and the transmission destination information Is. The control unit 20 may select the transmission destination 52 to which the determination result Rd and the improvement information Si are transmitted from among the multiple transmission destinations 52 based on the determination result Rd, the improvement information Si, and the transmission destination information Is. When the situation Sd is, for example, a situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value, the control unit 20 may control the transmission unit 50 to transmit the determination result Rd and the improvement information Si to at least one of the transmission destination 52-1 (a ventilation equipment company in this example) and the transmission destination 52-3 (a cleaning company in this example). When the measurement situation Sm is, for example, a situation in which the CO2 (carbon dioxide) sensor 400 is measured in an insufficiently calibrated state, the control unit 20 may control the transmission unit 50 to transmit the determination result Rd and the improvement information Si to the transmission destination 52-2 (a calibration equipment company in this example).

[0055] The determination device 100 may or may not further include a storage unit 43. In this example, the determination device 100 includes the storage unit 43. When the determination device 100 includes the storage unit 43, the storage unit 43 may store the destination information Is acquired by the information acquisition unit 42. The storage unit 43 may store at least one of the determination result Rd and the improvement information Si. When the determination device 100 does not include the storage unit 43, at least one of the destination information Is, the determination result Rd, and the improvement information Si may be stored in a server or a cloud server arranged outside the determination device 100.

[0056] Fig. 6 is a block diagram showing another example of a determination system 200 according to an embodiment of the present invention. In this example, the determination device 100 does not include a position information acquisition unit 40, and further includes an image acquisition unit 44. The determination system 200 of this example differs from the determination system 200 shown in Fig. 3 in this respect. The image acquisition unit 44 acquires an image of the determination target 500.

[0057] The mobile terminal 300 may include an imaging unit 410 that captures an image of the determination target 500. The imaging unit 410 is, for example, a camera. When the mobile terminal 300 is a smartphone, the imaging unit 410 may be a camera built into the smartphone. The wireless transmission unit 310 may transmit the image of the determination target 500 captured by the imaging unit 410 to the determination unit 10. The image acquisition unit 44 may acquire the image of the determination target 500 transmitted to the determination unit 10.

[0058] The control unit 20 may control the notification unit 30 to notify the determination result Rd and the improvement information Si to the notification unit 30. In this example, the control unit 20 controls the notification unit 30 to notify the determination result Rd and the improvement information Si to the notification unit 30 based on the image of the determination target 500 acquired by the image acquisition unit 44. In this example, the improvement information Si includes, for example, warning information, advertisement information of the transmission destination 52 (see FIG. 5), etc. The warning information is, for example, alert information indicating that the CO2 (carbon dioxide) concentration of the determination target 500 measured by the CO2 (carbon dioxide) sensor 400 has exceeded a predetermined concentration. The advertisement information of the transmission destination 52 (see FIG. 5) is, for example, advertisement information of a ventilation equipment company, advertisement information of a calibration equipment company, etc.

[0059] In this example, the judgment result Rd and the improvement information Si are notified to the notification unit 30 based on the image of the judgment target 500. Therefore, the user of the judgment device 100 can know the judgment result Rd and the improvement information Si by visually checking the notification unit 30.

[0060] The determination unit 10 may correct the determination result Rd based on the image acquired by the image acquisition unit 44. When the image acquired by the image acquisition unit 44 is an image of an equipment that may cause a deviation from the steady emission amount of CO2 (carbon dioxide) in the determination target 500, the determination unit 10 may correct the determination result Rd to the determination result Rd in the case where the concentration of CO2 (carbon dioxide) 510 measured by the CO2 (carbon dioxide) sensor 400 is corrected.

[0061] The judgment unit 10 may correct the judgment result Rd when an image of a predetermined device that emits a predetermined amount of CO2 (carbon dioxide) or more is acquired by the image acquisition unit 44. The predetermined amount of CO2 (carbon dioxide) may refer to the volume or mass of CO2 (carbon dioxide) emitted per unit time. A case where a predetermined amount or more of CO2 (carbon dioxide) is emitted means a case where the amount of CO2 (carbon dioxide) emission is unsteady, such as when fossil fuels are being burned in the judgment target 500.

[0062] The predetermined appliance that emits a predetermined amount of CO2 (carbon dioxide) or more may refer to an appliance that is highly likely to emit a predetermined amount of CO2 (carbon dioxide) or more. The appliance is, for example, an appliance that burns fossil fuel. The appliance is, for example, a stove. When the image acquired by the image acquisition unit 44 is an image of an appliance that burns fossil fuel, the appliance is highly likely to emit more CO2 (carbon dioxide) per unit time than an appliance that does not burn fossil fuel. Therefore, when the image acquired by the image acquisition unit 44 is, for example, an image of an appliance that burns fossil fuel, the determination unit 10 may correct the determination result Rd to a determination result Rd that indicates a higher concentration of CO2 (carbon dioxide) 510 than the concentration of CO2 (carbon dioxide) 510 measured by the CO2 (carbon dioxide) sensor 400.

[0063] The determination unit 10 may determine a measurement status Sm of the concentration of CO2 (carbon dioxide) 510 in the determination target 500 based on an image acquired by the image acquisition unit 44. The determination unit 10 may determine the measurement status Sm based on the concentration of CO2 (carbon dioxide) 510 and the image acquired by the image acquisition unit 44. The determination unit 10 may determine the measurement status Sm based on the image acquired by the image acquisition unit 44, not based on the concentration of CO2 (carbon dioxide) 510.

[0064] 7 is a block diagram showing another example of a determination system 200 according to an embodiment of the present invention. In this example, the determination device 100 includes a position information acquisition unit 40. The determination system 200 of this example differs from the determination system 200 shown in FIG. 6 in this respect.

[0065] In this example, the control unit 20 controls the notification unit 30 to notify the notification unit 30 of the judgment result Rd and the improvement information Si based on the image of the judgment target 500 acquired by the image acquisition unit 44 and the location information of the judgment target 500 acquired by the location information acquisition unit 40. Therefore, for example, when there are multiple destinations 52 (see FIG. 5), the advertising information of the vendor closest to the location of the judgment target 500 is more likely to be notified to the notification unit 30.

[0066] When the determination device 100 is a tablet or the like and the determination device 100 is moving, the dealer closest to the current location of the determination device 100 may change as the determination device 100 moves. When the determination device 100 is moving, the control unit 20 may change the improvement information Si to be notified by the notification unit 30 based on the image of the determination target 500 acquired by the image acquisition unit 44 and the location information of the determination device 100.

[0067] Fig. 8 is a block diagram showing another example of a determination system 200 according to an embodiment of the present invention. In this example, the determination device 100 further includes a motion sensor 60. The determination system 200 of this example differs from the determination system 200 shown in Fig. 3 in this respect. The motion sensor 60 detects at least one of the acceleration, angular velocity, and geomagnetic information of the determination device 100.

[0068] In this example, the improvement information Si is information based on at least one of the acceleration, angular velocity, and geomagnetic information of the determination device 100 measured by the motion sensor 60. When the determination device 100 is a smartphone, tablet, or the like, the determination device 100 is likely to be in a moving state. When the motion sensor 60 detects the acceleration of the determination device 100, the probability that the determination device 100 is moving is high. When the determination device 100 is moving, the user of the determination device 100 may be in a state where the user cannot visually recognize the notification unit 30. For this reason, when the motion sensor 60 detects the acceleration of the determination device 100, the control unit 20 may control the notification unit 30 so as not to notify the notification unit 30 of the determination result Rd. The control unit 20 may control the notification unit 30 to notify the notification unit 30 of the improvement information Si corresponding to the measurement situation Sm that the CO2 (carbon dioxide) concentration is measured in an environment in which the determination device 100 is moving.

[0069] In the case where the living body uses the determination device 100, if the motion sensor 60 detects acceleration associated with the body movement of the living body while sleeping, the determination device 100 may determine that the living body is in a sleeping state. The determination device 100 may control the notification unit 30 so as to notify the notification unit 30 of improvement information Si corresponding to the concentration of CO2 (carbon dioxide) 510 while the living body is sleeping. If the motion sensor 60 detects at least one of acceleration, angular velocity, and geomagnetic fluctuation associated with the movement of the living body while exercising, the determination device 100 may determine that the living body is in an exercising state. The determination device 100 may control the notification unit 30 so as to notify the notification unit 30 of improvement information Si corresponding to the concentration of CO2 (carbon dioxide) 510 while the living body is exercising.

[0070] Fig. 9 is a block diagram showing another example of the determination system 200 according to an embodiment of the present invention. In this example, the determination device 100 further includes an environmental sound measurement unit 62 instead of the position information acquisition unit 40 in Fig. 3. The determination system 200 of this example differs from the determination system 200 shown in Fig. 3 in this respect. The environmental sound measurement unit 62 measures environmental sound in the determination target 500. The environmental sound measurement unit 62 may measure the amplitude of the environmental sound.

[0071] In this example, the improvement information Si according to the measurement status Sm of the carbon dioxide concentration is information based on the environmental sound measured by the environmental sound measurement unit 62. For example, when the concentration of CO2 (carbon dioxide) 510 in the determination target 500 is measured in a situation where the CO2 (carbon dioxide) sensor 400 is placed at a position less than a predetermined distance from a wall, the CO2 (carbon dioxide) 510 is likely to remain within the range less than the predetermined distance.

[0072] The environmental sound measured by the environmental sound measuring unit 62 is defined as environmental sound S. The environmental sound S directed toward a wall is defined as environmental sound S1, and the environmental sound S reflected by the wall is defined as environmental sound S2. The time when the environmental sound S1 is measured by the environmental sound measuring unit 62 is defined as time T1, and the time when the environmental sound S2 is measured by the environmental sound measuring unit 62 is defined as time T2. The difference in time between time T2 and time T1 is defined as time ΔT. The sound speed of the environmental sound S1 and the environmental sound S2 is defined as sound speed Vs. Note that the environmental sound S2 is a so-called reverberant sound.

[0073] The control unit 20 can calculate twice the distance from the CO2 (carbon dioxide) sensor 400 to the wall by dividing the time ΔT by the sound speed Vs. This allows the control unit 20 to calculate the distance between the wall and the CO2 (carbon dioxide) sensor 400. Note that the environmental sound S1 may be a sound output by the audio output unit 32 (see FIG. 4). When the environmental sound S1 is a sound output by the audio output unit 32, the time T1 may be the time when the environmental sound S1 is output by the audio output unit 32.

[0074] The information acquisition unit 42 may acquire improvement information Si based on the environmental sound measured by the environmental sound measurement unit 62. The control unit 20 may control the notification unit 30 to notify the notification unit 30 of the determination result Rd and the improvement information Si.

[0075] The determination unit 10 may determine a measurement situation Sm of the concentration of CO2 (carbon dioxide) 510 in the determination target 500 based on the environmental sound measured by the environmental sound measurement unit 62. The determination unit 10 may determine the measurement situation Sm based on the concentration of CO2 (carbon dioxide) 510 and the environmental sound measured by the environmental sound measurement unit 62. The determination unit 10 may determine the measurement situation Sm based on the environmental sound measured by the environmental sound measurement unit 62, not based on the concentration of CO2 (carbon dioxide) 510.

[0076] When a living organism uses the determination device 100, if the environmental sound measuring unit 62 detects a sound associated with the breathing sound of the living organism while sleeping, the determination device 100 may determine that the living organism is in a sleeping state. The determination device 100 may control the notification unit 30 to notify the notification unit 30 of improvement information Si corresponding to the concentration of CO2 (carbon dioxide) 510 while the living organism is sleeping.

[0077] FIG. 10 is a block diagram showing an example of a determination device 100 according to an embodiment of the present invention. In this example, the determination device 100 includes a CO2 (carbon dioxide sensor) 400. In this example, the determination device 100 further includes a distance acquisition unit 46. The distance acquisition unit 46 acquires the distance between the CO2 (carbon dioxide sensor) 400 and the object 520. In this example, the distance acquisition unit 46 acquires the distance between the CO2 (carbon dioxide sensor) 400 and the object 520 based on an image acquired by the image acquisition unit 44. The distance is set as a distance d. Note that, when the distance acquisition unit 46 acquires the distance d not based on an image acquired by the image acquisition unit 44, the distance acquisition unit 46 may acquire the distance d by an optical range finder or LiDAR (Light Detection and Ranging).

[0078] The determination device 100 may include an imaging unit 410 that captures an image of the determination target 500. The imaging unit 410 is, for example, a camera. When the determination device 100 is a computer such as a tablet, the imaging unit 410 may be a camera built into the computer. The image acquisition unit 44 may acquire the image of the determination target 500 captured by the imaging unit 410.

[0079] The object 520 is a structure in the object 500 to be determined, and is a structure that can affect at least one of the state Sd of the CO2 (carbon dioxide) concentration and the measurement state Sm in the object 500 to be determined. The structure is, for example, a building. The object 520 may be a wall, a floor, a ceiling, a window, a door, or a living body of the structure. The living body may be a human body or an animal body.

[0080] The control unit 20 may control the notification unit 30 to notify the notification unit 30 of warning information when the distance d acquired by the distance acquisition unit 46 is less than a predetermined distance. The warning information may be warning information indicating that the measurement status Sm of the concentration of CO2 (carbon dioxide) 510 is inappropriate.

[0081] When the object 520 is, for example, a wall, CO2 (carbon dioxide) 510 is likely to remain within a range less than a predetermined distance from the object 520. Therefore, when the distance d between the CO2 (carbon dioxide sensor) 400 and the object 520 (wall) is less than the predetermined distance, the judgment result Rd for the judgment object 500 may be inaccurate. Therefore, when the distance d between the CO2 (carbon dioxide sensor) 400 and the object 520 (wall) is less than the predetermined distance, warning information may be notified to the notification unit 30. The predetermined distance is, for example, 50 cm.

[0082] When the object 520 is, for example, a window or a door, there is a high probability that two spaces with different concentrations of CO2 (carbon dioxide) 510 are connected by the window or the door. Therefore, the concentration of CO2 (carbon dioxide) 510 is likely to vary within a range less than a predetermined distance from the object 520 (window or door). Therefore, when the distance d between the CO2 (carbon dioxide sensor) 400 and the object 520 (window or door) is less than the predetermined distance, the judgment result Rd of the judgment object 500 may be inaccurate. Therefore, when the distance d between the CO2 (carbon dioxide sensor) 400 and the object 520 (window or door) is less than the predetermined distance, warning information may be notified to the notification unit 30. The predetermined distance is, for example, 1.5 m.

[0083] For example, when the object 520 is a living organism, the living organism exhale CO2 (carbon dioxide) by breathing, so that the concentration of CO2 (carbon dioxide) 510 is likely to be higher in a range less than a predetermined distance from the object 520 (living organism) than in a range of the predetermined distance or more. For this reason, when the distance d between the CO2 (carbon dioxide sensor) 400 and the object 520 (living organism) is less than the predetermined distance, the judgment result Rd of the judgment object 500 may be inaccurate. For this reason, when the distance d between the CO2 (carbon dioxide sensor) 400 and the object 520 (living organism) is less than the predetermined distance, the notification unit 30 may be notified of warning information. The predetermined distance is, for example, 1 m from the object 520 (living organism). The predetermined distance may be 2 m from the front of the object 520 (living organism) or 1 m from the side of the object 520 (living organism). When the living organism is a human being, the front of the living organism refers to a direction that is symmetrical with the spine as the center line. The side of a living body refers to a direction rotated 90 degrees to the left or right from the front, with the spine as the center line.

[0084] In this example, the determination device 100 may include a proximity sensor instead of the CO2 (carbon dioxide sensor) 400. In this example, the determination device 100 may include either the CO2 (carbon dioxide sensor) 400 or the proximity sensor, or may include both. The proximity sensor can detect that the distance d from the object 520 is less than a predetermined distance. When the object 520 is, for example, a human body and the determination device 100 is, for example, a smartphone, the proximity sensor can detect whether the person is talking on the phone. When the person is talking on the phone, the person may emit more CO2 (carbon dioxide) than when not talking on the phone, so the determination result Rd for the determination object 500 may be inaccurate. For this reason, when the distance d between the proximity sensor and the object 520 is less than a predetermined distance, the notification unit 30 may be notified of warning information. The predetermined distance is, for example, 10 cm. The proximity sensor may be an induction type proximity sensor, a capacitance type proximity sensor, or a magnetic proximity sensor.

[0085] Fig. 11 is a block diagram showing another example of the determination device 100 according to an embodiment of the present invention. The determination device 100 of this example differs from the determination device 100 shown in Fig. 10 in that it further includes an audio communication unit 48. The audio communication unit 48 communicates audio. The audio communication unit 48 transmits audio from the determination device 100 and receives audio from another device. The audio communication unit 48 is, for example, a microphone. The other device is, for example, another smartphone. The audio is, for example, a conversation.

[0086] The determination unit 10 may correct the determination result Rd when voice is being communicated by the voice communication unit 48. When voice is being communicated, for example, when the determination device 100 is a smartphone and a call is in progress. As described above, when a person is on a call, the person may emit more CO2 (carbon dioxide) than when the person is not on a call. For this reason, the CO2 (carbon dioxide) sensor 400 is likely to be constantly in contact with human breath that contains CO2 (carbon dioxide). The human breath is, for example, human exhalation. For this reason, when voice is being communicated by the voice communication unit 48, the determination unit 10 may correct the determination result Rd to a determination result Rd that indicates a concentration lower than the concentration of CO2 (carbon dioxide) 510 measured by the CO2 (carbon dioxide) sensor 400.

[0087] Fig. 12 is a block diagram showing another example of the determination system 200 according to an embodiment of the present invention. The determination system 200 may include a plurality of mobile terminals 300. In this example, the determination system 200 includes two mobile terminals 300 (mobile terminal 300-1 and mobile terminal 300-2). The determination system 200 of this example differs from the determination system 200 shown in Fig. 3 in that it includes two mobile terminals 300. In this example, the mobile terminal 300-1 is the first mobile terminal 300-1, and the mobile terminal 300-2 is the second mobile terminal 300-2.

[0088] Each of the multiple mobile terminals 300 may include a wireless transmission unit 310 and a CO2 (carbon dioxide) sensor 400. In this example, the first mobile terminal 300-1 includes a CO2 (carbon dioxide) sensor 400-1 and a wireless transmission unit 310-1, and the second mobile terminal 300-2 includes a CO2 (carbon dioxide) sensor 400-2 and a wireless transmission unit 310-2. The CO2 (carbon dioxide) sensor 400-1 measures the CO2 (carbon dioxide) concentration in the determination object 500-1. The CO2 (carbon dioxide) sensor 400-2 measures the CO2 (carbon dioxide) concentration in the determination object 500-2. The wireless transmission unit 310-1 transmits the concentration of CO2 (carbon dioxide) 510-1 measured by the CO2 (carbon dioxide) sensor 400-1 to the determination device 100. The wireless transmission unit 310-2 transmits to the determination device 100 the concentration of CO2 (carbon dioxide) 510-2 measured by the CO2 (carbon dioxide) sensor 400-2.

[0089] The determination unit 10 may determine the CO2 (carbon dioxide) concentration status Sd based on the concentration of CO2 (carbon dioxide) 510 in the determination target 500 and the concentration of CO2 (carbon dioxide) 510 in another determination target 500 different from the determination target 500. In this example, the determination unit 10 determines the CO2 (carbon dioxide) concentration status Sd based on the concentration of CO2 (carbon dioxide) 510-1 in the determination target 500-1 and the concentration of CO2 (carbon dioxide) 510-2 in the determination target 500-2. The determination target 500-1 and the determination target 500-2 are not in communication with each other.

[0090] In this example, the judgment unit 10 judges the CO2 (carbon dioxide) concentration status Sd of one of the judgment targets 500-1 and 500-2. In this example, when the judgment unit 10 judges the CO2 (carbon dioxide) concentration status Sd of the judgment target 500-1, the judgment unit 10 judges the CO2 (carbon dioxide) concentration status Sd of the judgment target 500-1 by comparing the CO2 (carbon dioxide) concentration of the judgment target 500-1 with the CO2 (carbon dioxide) concentration of the judgment target 500-2. Therefore, the judgment unit 10 can judge the status Sd more accurately than when judging the CO2 (carbon dioxide) concentration status Sd of one judgment target 500.

[0091] In the present example of the determination system 200, the determination device 100 is the same as the determination device 100 shown in FIG. 3, but the determination device 100 may be the same as the determination device 100 shown in any of FIGS. 1, 2, and 4 to 9.

[0092] Fig. 13 is a block diagram showing another example of the determination system 200 according to an embodiment of the present invention. In this example, a CO2 (carbon dioxide) sensor 400-1 of a first mobile terminal 300-1 and a CO2 (carbon dioxide) sensor 400-2 of a second mobile terminal 300-2 measure the concentration of CO2 (carbon dioxide) 510 in the same determination target 500. The determination system 200 of this example differs from the determination system 00 shown in Fig. 12 in this respect.

[0093] In this example, the wireless strength between the determination unit 10 and the wireless transmission unit 310-1 in the first mobile terminal 300-1 is defined as a first wireless strength Sw1. In this example, the wireless strength between the determination unit 10 and the wireless transmission unit 310-2 in the second mobile terminal 300-2 is defined as a second wireless strength Sw2. The determination unit 10 may determine the state of the CO2 (carbon dioxide sensor) 400 based on the first wireless strength Sw1 and the second wireless strength Sw2.

[0094] In this example, the CO2 (carbon dioxide) sensor 400-1 and the CO2 (carbon dioxide) sensor 400-2 measure the concentration of CO2 (carbon dioxide) 510 in the same determination target 500, so the ratio between the measured value of the concentration of CO2 (carbon dioxide) 510 by the CO2 (carbon dioxide) sensor 400-1 and the measured value of the concentration of CO2 (carbon dioxide) 510 by the CO2 (carbon dioxide) sensor 400-2 is highly likely to match within a predetermined error range centered on 1.0. Therefore, if the measured value of the concentration of CO2 (carbon dioxide) 510 by the CO2 (carbon dioxide) sensor 400-1 and the measured value of the concentration of CO2 (carbon dioxide) 510 by the CO2 (carbon dioxide) sensor 400-2 are outside the predetermined error range, a malfunction may occur in one of the CO2 (carbon dioxide) sensors 400.

[0095] The determination unit 10 may determine that the CO2 (carbon dioxide) sensor 400-1 in the first mobile terminal 300-1 is defective when the ratio (Sw1 / Sw2) of the first wireless strength Sw1 to the second wireless strength Sw2 is smaller than a predetermined value. The predetermined value is, for example, 0.1. The determination unit 10 may determine that the CO2 (carbon dioxide) sensor 400-1 in the first mobile terminal 300-1 is defective when the difference (Sw2-Sw1) between the second wireless strength Sw2 and the first wireless strength Sw1 is larger than the predetermined difference.

[0096] The judgment unit 10 may judge the position of the first portable terminal 300-1 in the judgment target 500 based on the first wireless intensity Sw1, and judge whether the CO2 (carbon dioxide) sensor 400-1 included in the first portable terminal 300-1 is good or bad based on the judgment result. The judgment unit 10 may judge the position of the second portable terminal 300-2 in the judgment target 500 based on the second wireless intensity Sw2, and judge whether the CO2 (carbon dioxide) sensor 400-2 included in the second portable terminal 300-2 is good or bad based on the judgment result.

[0097] The determination unit 10 may determine a measurement status Sm of the concentration of CO2 (carbon dioxide) 510 in the determination object 500 based on the first wireless strength Sw1 and the second wireless strength Sw2. The determination unit 10 may determine the measurement status Sm based on the concentration of CO2 (carbon dioxide) 510, and the first wireless strength Sw1 and the second wireless strength Sw2. The determination unit 10 may determine the measurement status Sm based on the first wireless strength Sw1 and the second wireless strength Sw2, not based on the concentration of CO2 (carbon dioxide) 510.

[0098] 14 is a block diagram showing another example of a determination system 200 according to an embodiment of the present invention. In the determination system 200 of this example, the determination device 100 further includes a distance acquisition unit 46. The determination system 200 of this example differs from the determination system 200 shown in FIG.

[0099] The distance acquisition unit 46 acquires the distance d between the CO2 (carbon dioxide) sensor 400 and the object 520. In this example, the distance acquisition unit 46 acquires the distance d between the CO2 (carbon dioxide) sensor 400 and the object 520 based on an image acquired by the image acquisition unit 44. As described above, the object 520 is a structure in the determination object 500, and is a structure that can affect at least one of the status Sd and the measurement status Sm of the CO2 (carbon dioxide) concentration in the determination object 500. Note that when the distance acquisition unit 46 acquires the distance d not based on the image acquired by the image acquisition unit 44, the distance acquisition unit 46 may acquire the distance d by an optical range finder or LiDAR (Light Detection and Ranging).

[0100] The control unit 20 may control the notification unit 30 to notify the notification unit 30 of warning information when the distance acquired by the distance acquisition unit 46 is less than a predetermined distance. The warning information may be warning information that the measurement status Sm of the concentration of CO2 (carbon dioxide) 510 is inappropriate.

[0101] Fig. 15 is a flowchart showing an example of a determination method according to an embodiment of the present invention. The determination method according to an embodiment of the present invention will be described by taking the determination system 200 shown in Fig. 1 as an example. The situation determination step S100 is a step in which the determination unit 10 determines the situation Sd of the concentration of CO2 (carbon dioxide) 510 in the determination target 500 based on the concentration of CO2 (carbon dioxide) 510 in the determination target 500. The measurement situation determination step S102 is a step in which the determination unit 10 determines the measurement situation Sm of the concentration of CO2 (carbon dioxide) 510 in the determination target 500 based on the concentration of CO2 (carbon dioxide) 510 in the determination target 500.

[0102] 15, in a situation determination step S100, the determination unit 10 determines a concentration situation Sd of CO2 (carbon dioxide) 510 in the determination object 500, and in a measurement situation determination step S102, the determination unit 10 determines a measurement situation Sm of the concentration of CO2 (carbon dioxide) 510 in the determination object 500. Therefore, a user of the determination method can know the concentration situation Sd and the measurement situation Sm of CO2 (carbon dioxide) 510 in the determination object 500.

[0103] The measurement situation determination step S102 may be performed after the situation determination step S100, or may be performed in parallel with the situation determination step S100. The situation determination step S100 may be performed after the measurement situation determination step S102.

[0104] The state determination step S100 may be a step in which the determination unit 10 determines the state Sd of the concentration of CO2 (carbon dioxide) 510 based on the time change of the concentration of CO2 (carbon dioxide) 510 in the determination target 500. This allows the user of the determination method to know the state Sd determined based on the time change of the concentration of CO2 (carbon dioxide) 510 and the measurement state Sm of the concentration of CO2 (carbon dioxide) 510.

[0105] The situation determination step S100 may be a step in which the determination unit 10 determines the situation Sd of the concentration of CO2 (carbon dioxide) 510 in the determination target 500 based on the concentration of CO2 (carbon dioxide) 510 in the determination target 500 and the concentration of CO2 (carbon dioxide) 510 in another determination target 500 different from the determination target 500. Taking the determination system 200 shown in Fig. 12 as an example, in the situation determination step S100, the determination unit 10 determines the situation Sd of the CO2 (carbon dioxide) concentration based on the concentration of CO2 (carbon dioxide) 510-1 in the determination target 500-1 and the concentration of CO2 (carbon dioxide) 510-2 in the determination target 500-2. The determination target 500-1 and the determination target 500-2 are not in communication with each other.

[0106] In the state determination step S100, the determination unit 10 determines the state Sd of the CO2 (carbon dioxide) concentration of one of the determination targets 500-1 and 500-2. In this example, when the determination unit 10 determines the state Sd of the CO2 (carbon dioxide) concentration of the determination target 500-1, the determination unit 10 determines the state Sd of the CO2 (carbon dioxide) concentration of the determination target 500-1 by comparing the CO2 (carbon dioxide) concentration of the determination target 500-1 with the CO2 (carbon dioxide) concentration of the determination target 500-2. Therefore, the determination unit 10 can more easily determine the state Sd more accurately than when determining the state Sd of the CO2 (carbon dioxide) concentration of one determination target 500.

[0107] Fig. 16 is a flowchart showing another example of a determination method according to an embodiment of the present invention. The determination method of this example differs from the determination method shown in Fig. 15 in that it further includes a position information acquisition step S104 and a control step S108. The determination method shown in Fig. 16 will be described taking the determination system 200 shown in Fig. 2 as an example.

[0108] The location information acquisition stage S104 is a stage in which the location information acquisition unit 40 acquires location information of the determination target 500. The control stage S108 is a stage in which the control unit 20 controls whether to notify the notification unit 30 of the determination result Rd by the determination unit 10 based on the location information of the determination target 500. As described above in the explanation of FIG. 2, when the location information is near a factory or the like, where the concentration of CO2 (carbon dioxide) 510 is constantly high compared to other areas near the factory, the control unit 20 does not need to notify the notification unit 30 of the determination result Rd by the determination unit 10.

[0109] Fig. 17 is a flowchart showing another example of a determination method according to an embodiment of the present invention. The determination method of this example differs from the determination method shown in Fig. 15 in that it further includes a position information acquisition step S104, an information acquisition step 106, and a control step S1081. The determination method shown in Fig. 17 will be described using the determination system 200 shown in Fig. 3 as an example.

[0110] The location information acquisition stage S104 is a stage in which the location information acquisition unit 40 acquires location information of the judgment target 500. The information acquisition stage S106 is a stage in which the information acquisition unit 42 acquires improvement information Si corresponding to at least one of the concentration status Sd of CO2 (carbon dioxide) 510 and the measurement status Sm of the concentration of CO2 (carbon dioxide) 510. The control stage S1081 is a stage in which the control unit 20 controls the notification unit 30 to notify the judgment result Rd by the judgment unit 10 and the improvement information Si based on the location information of the judgment target 500.

[0111] Since the determination method of this example includes a control step S1081, when the situation Sd is, for example, a situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value, in the control step S1081, advertisement information or the like of one or more businesses that are close to the position of the determination target 500 and that can resolve the situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value is notified to the notification unit 30. This allows the user of the determination method to know businesses that can resolve the situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value.

[0112] 5 as an example, in the information acquisition step S106, the information acquisition unit 42 may further acquire destination information Is relating to a destination to which the determination result Rd and the improvement information Si are to be transmitted. In the control step S1081, the control unit 20 may control the transmission unit 50 to transmit the determination result Rd and the improvement information Si to the destination based on the location information of the determination target 500. As a result, in the case where the situation Sd is, for example, a situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value, in the control step S1081, the determination result Rd and the improvement information Si are transmitted to a company that can resolve the situation in which the concentration of CO2 (carbon dioxide) 510 is an abnormal value and is closest to the current location of the determination target 500.

[0113] Fig. 18 is a flowchart showing another example of a determination method according to an embodiment of the present invention. The determination method of this example differs from the determination method shown in Fig. 15 in that it further includes an information acquisition step S106 and a control step S1082. The determination method shown in Fig. 18 will be described using the determination system 200 shown in Fig. 6 as an example.

[0114] The information acquisition stage S106 is a stage in which the information acquisition unit 42 acquires improvement information Si corresponding to at least one of the concentration status Sd of CO2 (carbon dioxide) 510 and the measurement status Sm of the concentration of CO2 (carbon dioxide) 510. The control stage S1082 is a stage in which the control unit 20 controls the notification unit 30 to notify the notification unit 30 of the determination result Rd by the determination unit 10 and the improvement information Si. The control stage S1082 may be a stage in which the control unit 20 controls the notification unit 30 to notify the notification unit 30 of the determination result Rd by the determination unit 10 and the improvement information Si based on the image acquired by the image acquisition unit 44.

[0115] In the determination method of this example, in the control step S1082, the determination result Rd and the improvement information Si are notified to the notification unit 30. Therefore, the user of the determination device 100 can know the determination result Rd and the improvement information Si by visually checking the notification unit 30.

[0116] Fig. 19 is a flowchart showing another example of a determination method according to an embodiment of the present invention. The determination method of this example differs from the determination method shown in Fig. 15 in that it further includes a carbon dioxide concentration measurement step S90, a distance acquisition step S107, and a control step S1083. The determination method shown in Fig. 19 will be described using the determination system 200 shown in Fig. 10 as an example.

[0117] The carbon dioxide concentration measurement stage S90 is a stage in which the CO2 (carbon dioxide) sensor 400 measures the concentration of CO2 (carbon dioxide) 510 in the determination target 500. The distance acquisition stage S107 is a stage in which the distance acquisition unit 46 acquires the distance between the CO2 (carbon dioxide) sensor 400 and the target 520. The distance acquisition stage S107 may be a stage in which the distance acquisition unit 46 acquires the distance between the CO2 (carbon dioxide) sensor 400 and the target 520 based on an image acquired by the image acquisition unit 44. Note that, in the distance acquisition stage S107, when the distance acquisition unit 46 acquires the distance d not based on an image acquired by the image acquisition unit 44, the distance acquisition stage S107 may be a stage in which the distance acquisition unit 46 acquires the distance d by an optical range finder or LiDAR (Light Detection and Ranging).

[0118] The object 520 may be a wall, a floor, a ceiling, a window, a door, or a living body of a structure, as described above in the description of Fig. 10. The control step S1083 is a step in which the control unit 20 controls the notification unit 30 to notify the notification unit 30 of warning information when the distance acquired by the distance acquisition unit 46 is less than a predetermined distance. The warning information may be warning information indicating that the measurement situation Sm of the concentration of CO2 (carbon dioxide) 510 is inappropriate.

[0119] Fig. 20 is a flowchart showing another example of a determination method according to an embodiment of the present invention. The determination method of this example differs from the determination method shown in Fig. 15 in that it further includes a wireless transmission step S95 and a state determination step S103. The determination method shown in Fig. 19 will be described using the determination system 200 shown in Fig. 13 as an example.

[0120] The wireless transmission step S95 is a step in which the wireless transmission unit 310 of each of the first portable terminal 300-1 and the second portable terminal 300-2 wirelessly transmits information on the concentration of CO2 (carbon dioxide) 510 measured by the CO2 (carbon dioxide) sensor 400 in the carbon dioxide concentration measurement step S90 to the determination unit 10. The state determination step S103 is a step in which the determination unit 10 determines the state of the CO2 (carbon dioxide) sensor 400 based on a first wireless intensity Sw1 between the wireless transmission unit 310 of the first portable terminal 300-1 and the determination unit 10 and a second wireless intensity Sw2 between the wireless transmission unit 310 of the second portable terminal 300-2 and the determination unit 10.

[0121] The status determination step S103 may be a step in which the determination unit 10 determines that the CO2 (carbon dioxide) sensor 400 of the first mobile terminal 300-1 is defective if the ratio of the first wireless strength Sw1 to the second wireless strength Sw2 is smaller than a predetermined value, or if the difference between the second wireless strength Sw2 and the first wireless strength Sw1 is larger than a predetermined difference.
