[Patent Literature 1] Japanese Unexamined Patent Application, Publication No. 2020-071621
The above summary of the invention does not enumerate all of the features of the invention. Subcombinations of these feature groups may also be inventive.
Hereinafter, the present invention will be described by way of embodiments of the invention, but the following embodiments are not intended to restrict the invention according to the claims. In addition, not all combinations of features described in the embodiments necessarily have to be essential to solving means of the invention.
The CO2 (carbon dioxide) sensor 400 is configured to measure a CO2 (carbon dioxide) concentration in a determination target 500. The determination target 500 is a target object that is a determination target related to the CO2 (carbon dioxide) concentration. The target object is, for example, a room in doors. The target object may be a predetermined space in open air. The CO2 (carbon dioxide) sensor 400 measures a concentration of CO2 (carbon dioxide) 510 contained in the air present in the target object.
When the determination target 500 is a room in doors, the mobile terminal 300 may be arranged inside the room. When the determination target 500 is a room in doors, the determination apparatus 100 may be arranged inside the room or may also be arranged outside the room.
In the present example, the mobile terminal 300 includes a wireless transmission unit 310. In the present example, the wireless transmission unit 310 is configured to transmit the concentration of the CO2 (carbon dioxide) 510 measured by the CO2 (carbon dioxide) sensor 400 to the determination apparatus 100.
The determination apparatus 100 includes a determination unit 10. The determination unit 10 is configured to determine, based on the CO2 (carbon dioxide) concentration in the determination target 500, a situation of the CO2 (carbon dioxide) concentration in the determination target 500 and a measurement situation of the CO2 (carbon dioxide) concentration in the determination target 500. In the present example, the CO2 (carbon dioxide) concentration in the determination target 500 is transmitted by the wireless transmission unit 310.
The determination unit 10 may be a central processing unit (CPU). The determination apparatus 100 may be a computer including the CPU, a memory, an interface, and the like. The determination apparatus 100 may also be a portable computer such as a tablet.
The situation of the CO2 (carbon dioxide) concentration in the determination target 500 is set as a situation Sd. The measurement situation of the CO2 (carbon dioxide) concentration in the determination target 500 is set as a measurement situation Sm. The situation Sd refers to at least one of an extent of the concentration and an extent of a concentration change of the CO2 (carbon dioxide) 510 in the determination target 500. The situation Sd refers to, for example, whether the CO2 (carbon dioxide) concentration in the determination target 500 is an abnormal value, is a normal value close to the abnormal value, rapidly approaches the abnormal value, or the like.
The measurement situation Sm refers to a situation related to a measurement environment of the concentration of the CO2 (carbon dioxide) 510 in the determination target 500. The measurement situation Sm refers to a situation such as, for example, whether the concentration of the CO2 (carbon dioxide) 510 in the determination target 500 is measured in a situation where human breath is in contact with the CO2 (carbon dioxide) sensor 400 or is measured in a situation where the CO2 (carbon dioxide) sensor 400 is arranged in a location close to a wall, whether the mobile terminal 300 having the CO2 (carbon dioxide) sensor 400 is on the move, or the like.
The determination unit 10 may output a determination result of the situation Sd and the measurement situation Sm. The determination result is set as a determination result Rd. With this configuration, a user of the determination apparatus 100 can find out the situation Sd and the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510 in the determination target 500.
The determination unit 10 may determine the situation Sd of the concentration of the CO2 (carbon dioxide) 510 based on a change over time of the concentration of the CO2 (carbon dioxide) 510. Since the situation Sd is determined based on the change over time of the concentration of the CO2 (carbon dioxide) 510, the user of the determination apparatus 100 can find out the situation Sd determined based on the change over time of the concentration of the CO2 (carbon dioxide) 510 and the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510. If the concentration of CO2 (carbon dioxide) 510 is increasing with time change, the determination unit 10 may determine that the situation Sd is in an abnormal state even if the concentration of CO2 (carbon dioxide) 510 is below a certain reference value. Time changes in the concentration of CO2 (carbon dioxide) 510 may include the time derivative, time integral, statistical distribution, statistic, time mean, variance per hour, deviation from the mean per hour, and predicted values of the concentration of CO2 (carbon dioxide) 510 after a certain time that are predicted from the time changes.
The notification unit 30 is configured to notify 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 perceived by a human visual sense. The notification unit 30 is, for example, a display, a monitor, or the like. The location information acquisition unit 40 is configured to acquire location information of the determination target 500. The location information acquisition unit 40 is, for example, a global positioning system (GPS). When the determination apparatus 100 is a portable computer such as a tablet, the notification unit 30 may be a display of the computer, and the location information acquisition unit 40 may be the GPS included in the computer. The location information acquisition unit 40 may also acquire location information of the determination apparatus 100.
The control unit 20 is configured to control, based on the location information of the determination target 500 which is acquired by the location information acquisition unit 40, whether the determination result Rd by the determination unit 10 is to be notified by the notification unit 30. The control unit 20 may control whether the determination result Rd is to be notified by the notification unit 30. The control unit 20 may be a central processing unit (CPU). The determination unit 10 and the control unit 20 may be a single CPU.
When the location information of the determination target 500 which is acquired by the location information acquisition unit 40 indicates, for example, a vicinity of a factory that causes combustion of a fossil fuel, the concentration of the CO2 (carbon dioxide) 510 in the vicinity of the factory may be steadily high as compared with a location other than the vicinity of the factory. In the situation Sd of the CO2 (carbon dioxide) concentration which is previously expected as described above where a response to the situation Sd is not necessary, a configuration may be adopted where the control unit 20 does not notify the determination result Rd by the determination unit 10 on the notification unit 30.
The determination unit 10 may also determine the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510 in the determination target 500 based on the location information of the determination target 500 which is acquired by the location information acquisition unit 40. The determination unit 10 may also determine the measurement situation Sm based on the concentration of the CO2 (carbon dioxide) 510 and the location information of the determination target 500. The determination unit 10 may also determine the measurement situation Sm not based on the concentration of the CO2 (carbon dioxide) 510, but based on the location information of the determination target 500.
In the present example, the improvement information Si according to the situation Sd refers to advertisement information or the like of a contractor who can improve or eliminate a factor causing the situation Sd. When the situation Sd is, for example, a situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value, the contractor who can improve or eliminate the factor is a ventilation contractor who can eliminate the abnormal value. When the situation Sd is, for example, a situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value, the improvement information Si may include improvement information for eliminating the abnormal value, maintenance information, or the like.
In the present example, the improvement information Si according to the measurement situation Sm refers to advertisement information or the like of a contractor who can remedy the measurement situation Sm. When the measurement situation Sm is, for example, a situation where the CO2 (carbon dioxide) sensor 400 performs the measurement in an insufficiently calibrated state, a contractor who can remedy the measurement situation Sm is a calibration contractor who can eliminate the insufficiently calibrated state.
In the present example, the control unit 20 controls the notification unit 30 in such a way as to notify the determination result Rd by the determination unit 10 and the improvement information Si on the notification unit 30 based on the location information of the determination target 500. Therefore, when the situation Sd is, for example, a situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value, the control unit 20 can notify the advertisement information or the like of one or more contractors who are close to the location of the determination target 500 and who can eliminate the situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value on the notification unit 30. With this configuration, the user of the determination apparatus 100 can find out the contractor who can eliminate the situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value. When having the notification unit 30 notify the determination result Rd and improvement information Si, the notification unit 30 may notify a plurality of contractors. The order in which the plurality of contractors are notified or the size of the notification or the like, may be prioritized. For example, the order of the above a contractor to be notified may change for each carbon dioxide concentration range, and certain a contractor may be notified at a higher priority.
The control unit 20 may change the determination result Rd and the improvement information Si which are to be notified by the notification unit 30 based on the location information of the determination target 500. The control unit 20 may control the notification unit 30 in such a way as to notify the determination result Rd and the improvement information Si which have been changed on the notification unit 30. When the determination apparatus 100 is, for example, a portable tablet or the like, the location information of the determination apparatus 100 changes along with the movement of the determination apparatus 100. Therefore, for example, the contractor who can eliminate the situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value and who is close to the current location of the determination target 500 may change along with the movement of the determination apparatus 100. When the contractor who is close to the current location of the determination target 500 changes along with the movement of the determination apparatus 100, the control unit 20 may change the determination result Rd and the improvement information Si to be notified by the notification unit 30 according to the location information of the determination target 500.
In the present example, the control unit 20 controls the sound output unit 32 in such a way as to cause the sound output unit 32 to output a sound related to the determination result Rd by the determination unit 10 and the improvement information Si based on the location information of the determination target 500. The sound related to the determination result Rd and the improvement information Si is, for example, a name or the like of a contractor who can eliminate the situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value.
The information acquisition unit 42 may further acquire transmission destination information regarding a transmission destination to which the determination result Rd and the improvement information Si are to be transmitted. The transmission destination is set as a transmission destination 52. The transmission destination information is set as transmission destination information Is. The transmission destination 52 may be at least one of the contractor who can eliminate the factor causing the situation Sd of the CO2 (carbon dioxide) concentration in the determination target 500 and the contractor who can remedy the measurement situation Sm of the CO2 (carbon dioxide) concentration in the determination target 500.
The information acquisition unit 42 may acquire the transmission destination information Is regarding a plurality of the transmission destinations 52. The information acquisition unit 42 may acquire the transmission destination information Is through an Internet line. In the present example, the information acquisition unit 42 acquires the transmission destination information Is regarding at least one of five transmission destinations 52 (transmission destination 52-1 to transmission destination 52-5). The information acquisition unit 42 may wirelessly acquire the transmission destination information Is. In
In the present example, the transmission destination 52-1 is a ventilation facility contractor, the transmission destination 52-2 is a calibration equipment contractor, the transmission destination 52-3 is a clearing contractor, the transmission destination 52-4 is a fire station, and the transmission destination 52-5 is an electronic commerce contractor. The ventilation facility contractor is, for example, a manufacturing contractor of an air conditioning facility. When the determination target 500 is a room in doors, the clearing contractor is, for example, a clearing contractor for a duct for discharging indoor air to an outdoor space. The electronic commerce contractor is, for example, a contractor who sells a product via the Internet. These transmission destinations are examples. The transmission destination 52 may be, for example, a contractor operating an application such as air quality management, or it may be an insurance company.
The control unit 20 may control the transmission unit 50 in such a way as to transmit the determination result Rd and the improvement information Si to the transmission destination 52 based on the location information of the determination target 500. The determination result Rd and the improvement information Si may be transmitted to the transmission destination 52 through the Internet line. In
In the present example, the determination result Rd and the improvement information Si are transmitted based on the location information of the determination target 500. Therefore, when the situation Sd is, for example, a situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value, the control unit 20 can control the transmission unit 50 in such a way as to transmit the determination result Rd and the improvement information Si to the contractor who can eliminate the situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value and who is the closest to the current location of the determination target 500. With this configuration, the closest contractor can more quickly arrive at the determination target 500 than a contractor farther from the current location of the determination target than the closest contractor.
The control unit 20 may control the transmission unit 50 in such a way as to transmit the determination result Rd and the improvement information Si to the transmission destination 52 further based on the determination result Rd and 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 to be transmitted from among the plurality of transmission destinations 52 based on the determination result Rd and the improvement information Si, and the transmission destination information Is. When the situation Sd is, for example, a situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value, the control unit 20 may control the transmission unit 50 in such a way as to transmit the determination result Rd and the improvement information Si to at least one of the transmission destination 52-1 (in the present example, the ventilation facility contractor) and the transmission destination 52-3 (in the present example, the clearing contractor). When the measurement situation Sm is, for example, a situation where the CO2 (carbon dioxide) sensor 400 performs the measurement in an insufficiently calibrated state, the control unit 20 may control the transmission unit 50 in such a way as to transmit the determination result Rd and the improvement information Si to the transmission destination 52-2 (in the present example, the calibration equipment contractor).
It should be noted that the determination apparatus 100 may further include a storage unit 43, or it may be sufficient without the storage unit 43. In the present example, the determination apparatus 100 includes the storage unit 43. When the determination apparatus 100 includes the storage unit 43, the storage unit 43 may store the transmission 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 apparatus 100 does not include the storage unit 43, at least one of the transmission 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 apparatus 100.
The mobile terminal 300 may include an image capturing unit 410 configured to capture an image of the determination target 500. The image capturing unit 410 is, for example, a camera. When the mobile terminal 300 is a smartphone, the image capturing unit 410 may be a camera built in the smartphone. The wireless transmission unit 310 may transmit the image of the determination target 500 which is captured by the image capturing unit 410 to the determination unit 10. The image acquisition unit 44 may acquire the image of the determination target 500 which is transmitted to the determination unit 10.
The control unit 20 may control the notification unit 30 in such a way as to notify the determination result Rd and the improvement information Si on the notification unit 30. In the present example, the control unit 20 controls the notification unit 30 in such a way as to notify the determination result Rd and the improvement information Si on the notification unit 30 based on the image of the determination target 500 which is acquired by the image acquisition unit 44. In the present example, the improvement information Si includes, for example, warning information, advertisement information of the transmission destination 52 (see
In the present example, the determination result Rd and the improvement information Si are notified by the notification unit 30 based on the image of the determination target 500. Therefore, the user of the determination apparatus 100 can find out the determination result Rd and the improvement information Si by visually recognizing the notification unit 30.
The determination unit 10 may correct the determination result Rd based on an image acquired by the image acquisition unit 44. When the image acquired by the image acquisition unit 44 is an image of equipment that may cause a deviation from a steady emission amount of the CO2 (carbon dioxide) in the determination target 500, the determination unit 10 may correct the determination result Rd to the determination result Rd in a case where the concentration of the CO2 (carbon dioxide) 510 measured by the CO2 (carbon dioxide) sensor 400 is corrected.
When an image of predetermined equipment that emits a predetermined amount or more of CO2 (carbon dioxide) is acquired by the image acquisition unit 44, the determination unit 10 may correct the determination result Rd. The predetermined amount of CO2 (carbon dioxide) may refer to a volume or a mass of CO2 (carbon dioxide) emitted per unit time. A case where the predetermined amount or more of CO2 (carbon dioxide) is emitted is a case where the emission amount of CO2 (carbon dioxide) is not steady such as a case where combustion of a fossil fuel is caused in the determination target 500.
The predetermined equipment that emits the predetermined amount or more of CO2 (carbon dioxide) may refer to equipment having a high probability that the predetermined amount or more of CO2 (carbon dioxide) is to be emitted. The equipment is, for example, equipment that causes combustion of a fossil fuel. The equipment is, for example, a space heater. When the image acquired by the image acquisition unit 44 is an image of the equipment that causes the combustion of the fossil fuel, the equipment has a high probability that the emission amount of CO2 (carbon dioxide) per unit time is higher than that of equipment that does not cause the combustion of the fossil fuel. Therefore, when the image acquired by the image acquisition unit 44 is, for example, an image of the equipment that causes the combustion of the fossil fuel, the determination unit 10 may correct the determination result Rd to the determination result Rd indicating a concentration higher than the concentration of the CO2 (carbon dioxide) 510 measured by the CO2 (carbon dioxide) sensor 400.
The determination unit 10 may also determine the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510 in the determination target 500 based on the image acquired by the image acquisition unit 44. The determination unit 10 may also determine the measurement situation Sm based on the concentration of the CO2 (carbon dioxide) 510 and the image acquired by the image acquisition unit 44. The determination unit 10 may also determine the measurement situation Sm not based on the concentration of the CO2 (carbon dioxide) 510, but based on the image acquired by the image acquisition unit 44.
In the present example, the control unit 20 controls the notification unit 30 in such a way as to notify the determination result Rd and the improvement information Si on the notification unit 30 based on the image of the determination target 500 which is acquired by the image acquisition unit 44 and the location information of the determination target 500 which is acquired by the location information acquisition unit 40. Therefore, for example, when the plurality of transmission destinations 52 (see
When the determination apparatus 100 is a tablet or the like and the determination apparatus 100 is on the move, the contractor closest to the current location of the determination apparatus 100 may change along with the movement of the determination apparatus 100. When the determination apparatus 100 is on the move, 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 which is acquired by the image acquisition unit 44 and the location information of the determination apparatus 100.
In the present example, the improvement information Si is information based on at least one of the acceleration, the angular rate, and the terrestrial magnetism information of the determination apparatus 100 which are measured by the motion sensor 60. When the determination apparatus 100 is a smartphone, a tablet, or the like, the determination apparatus 100 tends to be in a moving state. When the motion sensor 60 detects the acceleration of the determination apparatus 100, a probability that the determination apparatus 100 is on the move is high. When the determination apparatus 100 is on the move, the user of the determination apparatus 100 may be in a state where it is not possible to visibly recognize the notification unit 30. Therefore, when the motion sensor 60 detects the acceleration of the determination apparatus 100, the control unit 20 may control the notification unit 30 in such a way as to avoid notification of the determination result Rd on the notification unit 30. The control unit 20 may also control the notification unit 30 in such a way as to notify, on the notification unit 30, the improvement information Si according to the measurement situation Sm indicating that the CO2 (carbon dioxide) concentration is measured under an environment where the determination apparatus 100 is on the move.
When a living body uses the determination apparatus 100, if the motion sensor 60 detects acceleration associated with body movements during sleep of the said living body, the determination apparatus 100 may determine that the said living body is in a sleep state. The determination apparatus 100 may control the notification unit 30 to notify the notification unit 30 of the improvement information Si according to the concentration of CO2 (carbon dioxide) 510 while the said living body is sleeping. If the motion sensor 60 detects at least one of acceleration, angular velocity, and geomagnetic variation associated with the motion of the said living body in motion, the determination apparatus 100 may determine that the said living body is in motion. The determination apparatus 100 may control the notification unit 30 to notify the notification unit 30 of the improvement information Si according to the concentration of CO2 (carbon dioxide) 510 during exercise by the said living body.
In the present example, the improvement information Si according to the measurement situation Sm of the carbon dioxide concentration is information based on the environmental sound measured by the environmental sound measurement unit 62. When the concentration of the CO2 (carbon dioxide) 510 in the determination target 500 is measured in a situation where, for example, the CO2 (carbon dioxide) sensor 400 is arranged in a location at a distance that is shorter than a predetermined distance from a wall, the CO2 (carbon dioxide) 510 tends to remain in a range under the predetermined distance.
The environmental sound measured by the environmental sound measurement unit 62 is set as an environmental sound S. The environmental sound S heading towards a wall is set as an environmental sound S1, and the environmental sound S reflected by the wall is set as an environmental sound S2. A clock time at which the environmental sound S1 is measured by the environmental sound measurement unit 62 is set as a clock time T1, and a clock time at which the environmental sound S2 is measured by the environmental sound measurement unit 62 is set as a clock time T2. A time period of a difference between the clock time T2 and the clock time T1 is set as a time period ΔT. A sound velocity of the environmental sound S1 and the environmental sound S2 is set as a sound velocity Vs. It should be noted that the environmental sound S2 is a so called reverberant sound.
The control unit 20 can calculate a distance that is twice as long as a distance from the CO2 (carbon dioxide) sensor 400 to a wall by dividing the time period ΔT by the sound velocity Vs. With this configuration, the control unit 20 can calculate a distance between the wall and the CO2 (carbon dioxide) sensor 400. It should be noted that the environmental sound S1 may be a sound output by the sound output unit 32 (see
The information acquisition unit 42 may acquire the 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 in such a way as to notify the determination result Rd and the improvement information Si on the notification unit 30.
The determination unit 10 may also determine the measurement situation Sm of the concentration of the 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 also determine the measurement situation Sm based on the concentration of the CO2 (carbon dioxide) 510 and the environmental sound measured by the environmental sound measurement unit 62. The determination unit 10 may also determine the measurement situation Sm not based on the concentration of the CO2 (carbon dioxide) 510, but based on the environmental sound measured by the environmental sound measurement unit 62.
When the living body uses the determination apparatus 100, if the environmental sound measurement unit 62 detects a sound associated with the sound of breathing during sleep of the living body, the determination apparatus 100 may determine that the living body is in a sleep state. The determination apparatus 100 may control the notification unit 30 to notify the notification unit 30 of the improvement information Si according to the concentration of CO2 (carbon dioxide) 510 while the said living body is sleeping.
The determination apparatus 100 may include the image capturing unit 410 configured to capture an image of the determination target 500. The image capturing unit 410 is, for example, a camera. When the determination apparatus 100 is a computer such as a tablet, the image capturing unit 410 may be a camera built in the computer. The image acquisition unit 44 may acquire the image of the determination target 500 which is captured by the image capturing unit 410.
The target object 520 is a structural object in the determination target 500 which is a structural object that may affect at least one of the situation Sd and the measurement situation Sm of the CO2 (carbon dioxide) concentration in the determination target 500. The structural object is, for example, a building. The target object 520 may be a wall, floor, a ceiling, a window, or a door of the structural object or a living body. The living body may be a human body or may also be a body of an animal.
When the distance d acquired by the distance acquisition unit 46 is shorter than a predetermined distance, the control unit 20 may control the notification unit 30 in such a way as to notify warning information on the notification unit 30. The warning information may be warning information indicating that the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510 is inappropriate.
When the target object 520 is, for example, a wall, the CO2 (carbon dioxide) 510 tends to remain in a range under a predetermined distance from the target object 520. For this reason, when the distance d between the CO2 (carbon dioxide) sensor 400 and the target object 520 (wall) is shorter than the predetermined distance, the determination result Rd in the determination target 500 may be inaccurate. Therefore, when the distance d between the CO2 (carbon dioxide) sensor 400 and the target object 520 (wall) is shorter than the predetermined distance, the warning information may be notified by the notification unit 30. The predetermined distance is, for example, 50 cm.
When the target object 520 is, for example, a window or a door, a probability is high that two spaces where the concentration of the CO2 (carbon dioxide) 510 is different from each other are interconnected by the window or the door. For this reason, the concentration of the CO2 (carbon dioxide) 510 tends to fluctuate in a range under a predetermined distance from the target object 520 (window or door). For this reason, when the distance d between the CO2 (carbon dioxide) sensor 400 and the target object 520 (window or door) is shorter than the predetermined distance, the determination result Rd in the determination target 500 may be inaccurate. Therefore, when the distance d between the CO2 (carbon dioxide) sensor 400 and the target object 520 (window or door) is shorter than the predetermined distance, the warning information may be notified by the notification unit 30. The predetermined distance is, for example, 1.5 m.
When the target object 520 is, for example, a living body, since the living body emits CO2 (carbon dioxide) through breathing, the concentration of the CO2 (carbon dioxide) 510 tends to be higher in a range under a predetermined distance from the target object 520 (living body) than that in a range at and beyond the predetermined distance. For this reason, the distance d between the CO2 (carbon dioxide) sensor 400 and the target object 520 (living body) is shorter than the predetermined distance, the determination result Rd in the determination target 500 may be inaccurate. Therefore, when the distance d between the CO2 (carbon dioxide) sensor 400 and the target object 520 (living body) is shorter than the predetermined distance, the warning information may be notified by the notification unit 30. The predetermined distance is, for example, 1 m from the target object 520 (living body). The predetermined distance may be 2 m from a front of the target object 520 (living body), or may also be 1 m from a side of the target object 520 (living body). When the living body is a person, the front of the living body refers to an orientation in which the person has bilateral symmetry by setting a spine as a center line. The side of the living body refers to an orientation in which the person is rotated by 90 degrees in either left or right direction with respect to the front by setting the spine as the center line.
In the present example, the determination apparatus 100 may include a proximity sensor instead of the CO2 (carbon dioxide) sensor 400. In the present example, the determination apparatus 100 may include one of the CO2 (carbon dioxide) sensor 400 and the proximity sensor, and may also include both of those sensors. The proximity sensor can detect that the distance d to the target object 520 is shorter than a predetermined distance. When the target object 520 is, for example, a human body and also the determination apparatus 100 is, for example, a smartphone, the proximity sensor may detect whether a person is in a call. When the person is in a call, since the person may emit more CO2 (carbon dioxide) as compared with a case where the person is not in a call, the determination result Rd in the determination target 500 may be inaccurate. Therefore, when the distance d between the proximity sensor and the target object 520 is shorter than the predetermined distance, the warning information may be notified by the notification unit 30. The predetermined distance is, for example, 10 cm. It should be noted that the proximity sensor may be an induction type proximity sensor, may also be a capacitive proximity sensor, or may also be a magnetic proximity sensor.
In a case where the sound is communicated by the sound communication unit 48, the determination unit 10 may correct the determination result Rd. A case where the sound is communicated is, for example, a case of an active call when the determination apparatus 100 is a smartphone. As described above, when the person is in a call, the person may emit more CO2 (carbon dioxide) as compared with a case where the person is not in a call. For this reason, the CO2 (carbon dioxide) sensor 400 tends to be in a state in steady contact with a human breath that is a breath containing CO2 (carbon dioxide). The human breath is, for example, an expiratory air of a person. Therefore, in a case where the sound is communicated by the sound communication unit 48, the determination unit 10 may correct the determination result Rd to the determination result Rd indicating a concentration lower than the concentration of the CO2 (carbon dioxide) 510 measured by the CO2 (carbon dioxide) sensor 400.
Each of the plurality of mobile terminals 300 may include the wireless transmission unit 310 and the CO2 (carbon dioxide) sensor 400. In the present 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 is configured to measure a CO2 (carbon dioxide) concentration in a determination target 500-1. The CO2 (carbon dioxide) sensor 400-2 is configured to measure a CO2 (carbon dioxide) concentration in a determination target 500-2. The wireless transmission unit 310-1 is configured to transmit a concentration of CO2 (carbon dioxide) 510-1 measured by the CO2 (carbon dioxide) sensor 400-1 to the determination apparatus 100. The wireless transmission unit 310-2 is configured to transmit a concentration of CO2 (carbon dioxide) 510-2 measured by the CO2 (carbon dioxide) sensor 400-2 to the determination apparatus 100.
The determination unit 10 may determine the situation Sd of the CO2 (carbon dioxide) concentration based on the concentration of the CO2 (carbon dioxide) 510 in the determination target 500 and a concentration of CO2 (carbon dioxide) 510 in another determination target 500 different from the determination target 500. In the present example, the determination unit 10 determines the situation Sd of the CO2 (carbon dioxide) concentration based on the concentration of the CO2 (carbon dioxide) 510-1 in the determination target 500-1 and the concentration of the CO2 (carbon dioxide) 510-2 in the determination target 500-2. The determination target 500-1 and the determination target 500-2 are not interconnected.
In the present example, the determination unit 10 determines the situation Sd of the CO2 (carbon dioxide) concentration of one of the determination target 500-1 and the determination target 500-2. In the present example, when the determination unit 10 is to determine the situation Sd of the CO2 (carbon dioxide) concentration in the determination target 500-1, the determination unit 10 compares the CO2 (carbon dioxide) concentration in the determination target 500-1 with the CO2 (carbon dioxide) concentration in the determination target 500-2 to determine the situation Sd of the CO2 (carbon dioxide) concentration in the determination target 500-1. Therefore, the determination unit 10 more easily determines the more accurate situation Sd as compared with a case where the situation Sd of the CO2 (carbon dioxide) concentration in the single determination target 500 is to be determined.
In the determination system 200 of the present example, the determination apparatus 100 has a mode of the determination apparatus 100 illustrated in
In the present example, a radio intensity between the determination unit 10 and the wireless transmission unit 310-1 in the first mobile terminal 300-1 is set as a first radio intensity Sw1. In the present example, a radio intensity between the determination unit 10 and the wireless transmission unit 310-2 in the second mobile terminal 300-2 is set as a second radio intensity Sw2. The determination unit 10 may determine a state of the CO2 (carbon dioxide) sensor 400 based on the first radio intensity Sw1 and the second radio intensity Sw2.
In the present example, since the CO2 (carbon dioxide) sensor 400-1 and the CO2 (carbon dioxide) sensor 400-2 measure the concentration of the CO2 (carbon dioxide) 510 in the identical determination target 500, a probability is high that a ratio of a measured value of the concentration of the CO2 (carbon dioxide) 510 by the CO2 (carbon dioxide) sensor 400-1 to a measured value of the concentration of the CO2 (carbon dioxide) 510 by the CO2 (carbon dioxide) sensor 400-2 is matched within a predetermined error range with 1.0 as a center. Therefore, when the measured value of the concentration of the CO2 (carbon dioxide) 510 by the CO2 (carbon dioxide) sensor 400-1 and the measured value of the concentration of the CO2 (carbon dioxide) 510 by the CO2 (carbon dioxide) sensor 400-2 are out of the predetermined error range, a defect may have occurred in one of the CO2 (carbon dioxide) sensors 400.
When a ratio (Sw1/Sw2) of the first radio intensity Sw1 to the second radio intensity Sw2 is lower than a predetermined value, the determination unit 10 may determine that the CO2 (carbon dioxide) sensor 400-1 in the first mobile terminal 300-1 is faulty. The predetermined value is, for example, 0.1. When a difference (Sw2-Sw1) between the second radio intensity Sw2 and the first radio intensity Sw1 is larger than a predetermined difference, the determination unit 10 may determine that the CO2 (carbon dioxide) sensor 400-1 in the first mobile terminal 300-1 is faulty.
The determination unit 10 may determine a location of the first mobile terminal 300-1 in the determination target 500 based on the first radio intensity Sw1, and determine whether the CO2 (carbon dioxide) sensor 400-1 included in the first mobile terminal 300-1 is operative or faulty based on the determination result. The determination unit 10 may determine a location of the second mobile terminal 300-2 in the determination target 500 based on the second radio intensity Sw2, and determine whether the CO2 (carbon dioxide) sensor 400-2 included in the second mobile terminal 300-2 is operative or faulty based on the determination result.
The determination unit 10 may determine the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510 in the determination target 500 based on the first radio intensity Sw1 and the second radio intensity Sw2. The determination unit 10 may determine the measurement situation Sm based on the concentration of the CO2 (carbon dioxide) 510, and the first radio intensity Sw1 and the second radio intensity Sw2. The determination unit 10 may determine the measurement situation Sm not based on the concentration of the CO2 (carbon dioxide) 510, but based on the first radio intensity Sw1 and the second radio intensity Sw2.
The distance acquisition unit 46 is configured to acquire the distance d between the CO2 (carbon dioxide) sensor 400 and the target object 520. In the present example, the distance acquisition unit 46 acquires the distance d between the CO2 (carbon dioxide) sensor 400 and the target object 520 based on the image acquired by the image acquisition unit 44. As described above, the target object 520 is a structural object in the determination target 500 which is a structural object that may affect at least one of the situation Sd and the measurement situation Sm of the CO2 (carbon dioxide) concentration in the determination target 500. It should be noted that when the distance acquisition unit 46 is to acquire 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 electro-optical distance meter or light detection and ranging (LiDAR).
When the distance d acquired by the distance acquisition unit 46 is shorter than a predetermined distance, the control unit 20 may control the notification unit 30 in such a way as to notify warning information on the notification unit 30. The warning information may be warning information indicating that the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510 is inappropriate.
According to the determination method illustrated in
It should be noted that the measurement situation determination step S102 may be performed after the situation determination step S100, or may also be performed in parallel with the situation determination step S100. The situation determination step S100 may also be performed after the measurement situation determination step S102.
The situation determination step S100 may be a step where the determination unit 10 determines the situation Sd of the concentration of the CO2 (carbon dioxide) 510 based on the change over time of the concentration of the CO2 (carbon dioxide) 510 in the determination target 500. With this configuration, the user of the determination method can find out the situation Sd determined based on the change over time of the concentration of the CO2 (carbon dioxide) 510, and the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510.
The situation determination step S100 may be a step where the determination unit 10 determines the situation Sd of the concentration of the CO2 (carbon dioxide) 510 in the determination target 500 based on the concentration of the CO2 (carbon dioxide) 510 in the determination target 500 and a concentration of CO2 (carbon dioxide) 510 in another determination target 500 different from the determination target 500. A description will be provided while the determination system 200 illustrated in
In the situation determination step S100, the determination unit 10 determines the situation Sd of the CO2 (carbon dioxide) concentration of one of the determination target 500-1 and the determination target 500-2. In the present example, when the determination unit 10 is to determine the situation Sd of the CO2 (carbon dioxide) concentration in the determination target 500-1, the determination unit 10 compares the CO2 (carbon dioxide) concentration of the determination target 500-1 with the CO2 (carbon dioxide) concentration of the determination target 500-2 to determine the situation Sd of the CO2 (carbon dioxide) concentration in the determination target 500-1. Therefore, the determination unit 10 more easily determines the more accurate situation Sd as compared with a case where the situation Sd of the CO2 (carbon dioxide) concentration in the single determination target 500 is to be determined.
The location information acquisition step S104 is a step where the location information acquisition unit 40 acquires the location information of the determination target 500. The control step S108 is a step where the control unit 20 controls whether the determination result Rd by the determination unit 10 is to be notified by the notification unit 30 based on the location information of the determination target 500. As mentioned above in the description of
The location information acquisition step S104 is a step where the location information acquisition unit 40 acquires the location information of the determination target 500. The information acquisition step S106 is a step where the information acquisition unit 42 acquires the improvement information Si according to at least one of the situation Sd of the concentration of the CO2 (carbon dioxide) 510 and the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510. The control step S1081 is a step where the control unit 20 controls the notification unit 30 in such a way as to notify the determination result Rd by the determination unit 10 and the improvement information Si on the notification unit 30 based on the location information of the determination target 500.
Since the determination method of the present example includes the control step S1081, when the situation Sd is, for example, a situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value, in the control step S1081, advertisement information or the like of one or more contractors who are close to the location of the determination target 500 corresponding to contractors who can eliminate the situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value is notified by the notification unit 30. With this configuration, the user of the determination method can find out the contractor who can eliminate the situation where the concentration of the CO2 (carbon dioxide) 510 is an abnormal value.
A description will be provided while the determination system 200 illustrated in
The information acquisition step S106 is a step where the information acquisition unit 42 acquires the improvement information Si according to at least one of the situation Sd of the concentration of the CO2 (carbon dioxide) 510 and the measurement situation Sm of the concentration of the CO2 (carbon dioxide) 510. The control step S1082 is a step where the control unit 20 controls the notification unit 30 in such a way as to notify the determination result Rd by the determination unit 10 and the improvement information Si on the notification unit 30. The control step S1082 may also be a step where the control unit 20 controls the notification unit 30 in such a way as to notify the determination result Rd by the determination unit 10 and the improvement information Si on the notification unit 30 based on the image acquired by the image acquisition unit 44.
According to determination method of the present example, in the control step S1082, the determination result Rd and the improvement information Si are notified by the notification unit 30. Therefore, the user of the determination apparatus 100 can find out the determination result Rd and the improvement information Si by visibly recognizing the notification unit 30.
The carbon dioxide concentration measurement step S90 is a step where the CO2 (carbon dioxide) sensor 400 measures the concentration of the CO2 (carbon dioxide) 510 in the determination target 500. The distance acquisition step S107 is a step where the distance acquisition unit 46 acquires a distance between the CO2 (carbon dioxide) sensor 400 and the target object 520. The distance acquisition step S107 may be a step where the distance acquisition unit 46 acquires a distance between the CO2 (carbon dioxide) sensor 400 and the target object 520 based on the image acquired by the image acquisition unit 44. It should be noted that in the distance acquisition step S107, when the distance acquisition unit 46 is to acquire the distance d not based on the image acquired by the image acquisition unit 44, the distance acquisition step S107 may also be a step where the distance acquisition unit 46 acquires the distance d by an electro-optical distance meter or light detection and ranging (LiDAR).
The target object 520 may be a wall, a floor, a ceiling, a window, or a door of a structural object or a living body as described in the description of
The wireless transmission step S95 is a step where the wireless transmission unit 310 included in each of the first mobile terminal 300-1 and the second mobile terminal 300-2 wirelessly transmits information of the concentration of the 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 where the determination unit 10 determines a state of the CO2 (carbon dioxide) sensor 400 based on the first radio intensity Sw1 between the wireless transmission unit 310 in the first mobile terminal 300-1 and the determination unit 10 and the second radio intensity Sw2 between the wireless transmission unit 310 in the second mobile terminal 300-2 and the determination unit 10.
The state determination step S103 may be a step where when a ratio of the first radio intensity Sw1 to the second radio intensity Sw2 is lower than a predetermined value or a difference between the second radio intensity Sw2 and the first radio intensity Sw1 is larger than a predetermined difference, the determination unit 10 determines that the CO2 (carbon dioxide) sensor 400 of the first mobile terminal 300-1 is faulty.
