Description

[Technical field]

[0001] The present invention relates to a gate device. [Background technology]

[0002] A technology is known that determines whether or not a subject has cancer by the reaction of nematodes to the smell of urine (Patent Document 1). It is also said that COVID-19, a new coronavirus that has been raging in recent years, has a unique odor in the patient's metabolites. There is also a technology known that uses trained dogs to detect the odor of metabolites from patients infected with COVID-19.

[0003] Also known is an odor sensor including a plurality of sensor elements each having different sensitivity selectivity to gases. Also known is a technology for identifying the type of odor by using an algorithm such as AI (Artificial Intelligence) based on sensor data detected by an odor sensor including a plurality of sensor elements.

[0004] Patent Document 2 describes a security gate that manages the entrance and exit of users. This security gate opens when the body temperature of a user is lower than a set value. This makes it possible for this security gate to restrict people with a body temperature higher than the set value from entering an office or the like, thereby preventing mass infections of influenza or the like. Patent Document 3 describes an individual processing method that changes processing depending on whether or not a person passing through the gate corresponds to a specific person. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-031649 A [Patent Document 2] JP 2011-085004 A [Patent Document 3] JP 2017-167931 A Summary of the Invention [Problem to be solved by the invention]

[0006] Incidentally, in an environment where an epidemic disease such as COVID-19 is prevalent, it is effective to install a gate device that allows people to enter a specific area on the condition that they are not infected with a specific disease or virus in order to prevent mass infection. For example, known methods for testing whether or not someone is infected with COVID-19 include PCR (Polymerase Chain Reaction) testing, antibody testing, and antigen testing. However, all of these tests take time to obtain results. Therefore, none of these tests are effective as a testing method to be performed in a gate device.

[0007] One option is to use trained dogs to carry out inspections at gate devices, but training dogs takes a lot of time and there is a possibility that the detection accuracy may vary.

[0008] Another possible method is to check the body temperature of people passing through the gate device. However, this method has poor detection accuracy, as people with a body temperature higher than a set value are not necessarily infected with a specific virus, and people with a body temperature below the set value may still be infected with a specific virus.

[0009] The present invention has been made in consideration of the above, and aims to provide a gate device that can simply, quickly and accurately restrict people suffering from a specific disease or infected with a specific virus from entering a specific area. [Means for solving the problem]

[0010] In order to solve the above problems and achieve the object, the gate device according to the present invention includes a first gate that restricts a subject from entering a first area from an inspection area; A second gate that guides the subject from the examination area to a second area different from the first area; The odor sensor detects odors located in the inspection area. BeforeDetect the smell of a specific object worn by the subject, The subject is wearing An inspection device that outputs odor data representing the odor of the specific object, and The subject is wearing Indicating whether the odor of the specific object is a specific odor or not No. 1 Judgment result and a second determination result indicating whether the odor of the specific object worn by the subject is the odor of the specific object when not worn by the subject. Get The first gate and the second gate are controlled based on the first determination result and the second determination result. A control device. The control device controls the first gate to allow the subject to enter the first area when the odor of the specific object worn by the subject is not the specific odor and is not the odor of the specific object when not worn by the subject, and controls the second gate to guide the subject to the second area when the odor of the specific object worn by the subject is the specific odor or the odor of the specific object when not worn by the subject. . Effect of the Invention

[0011] According to the present invention, it is possible to restrict people suffering from a particular disease or infected with a particular virus from entering a particular area. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] FIG. 1 is a diagram showing a gate system 10 according to an embodiment.

[0014] The gate system 10 determines whether or not an odor emitted by a specific metabolite in a subject or a specific object worn by the subject is a specific odor. If the odor emitted by the specific metabolite or specific object is not the specific odor, the gate system 10 permits the subject to enter the first area, and if the odor of the specific metabolite or specific object is the specific odor, the gate system 10 restricts the subject from entering the first area.

[0015] The gate system 10 includes a management device 18, a gate device 20, and a determination device 22. In this embodiment, the gate device 20, the determination device 22, and the management device 18 are connected via a network. Alternatively, the gate system 10 may include at least one of the determination device 22 and the management device 18 within the gate device 20.

[0016] The management device 18 stores user information that identifies a user registered in advance. The management device 18 also acquires, for example, input information input by a subject at the gate device 20 from the gate device 20. The input information is, for example, information read from a card or the like, information input by the subject into a keyboard, or facial image data obtained by capturing an image of the subject's face. The management device 18 authenticates whether or not the subject is a user registered in advance based on the acquired input information. Then, the management device 18 sends the authentication result to the gate device 20.

[0017] The gate device 20 is provided at the boundary between the first area and the external area. The first area is a specific area where it is desired to prevent people suffering from a specific disease or infected with a specific virus from entering. For example, the first area may be an area where it is difficult to take measures to prevent infection. For example, the first area may be an event venue, a live music venue, a sports gym, a gymnasium, etc. For example, general users cannot enter the first area from any entrance other than the gate device 20. The external area is an area different from the first area. For example, it is an area where various people can pass through or stay without any restrictions.

[0018] The gate device 20 includes a shielding wall 32, an inspection area gate 34, an authentication device 36, a first gate 38, a second gate 40, an inspection device 44, and a control device 46.

[0019] The test area is shielded from the surrounding space by the shielding wall 32. The test area is an area for detecting a specific metabolite of a subject or an odor of a specific object.

[0020] The inspection area gate 34 restricts the subject from entering the inspection area from the external area. The inspection area gate 34 opens between the external area and the inspection area in response to control by the control device 46, and permits the subject to enter the inspection area from the external area.

[0021] The authentication device 36 accepts an input operation of input information from the subject before the subject enters the inspection area. The authentication device 36 sends the input information to the management device 18 and obtains the authentication result of the subject from the management device 18. The authentication device 36 causes the inspection area gate 34 to permit the subject to enter the inspection area from the external area on the condition that the subject has been authenticated by the management device 18, for example, on the condition that the subject is a user registered in advance.

[0022] The first gate 38 restricts the subject from entering the first area from the inspection area. The first gate 38 opens between the inspection area and the first area in response to control by the control device 46, and allows the subject to enter the first area from the inspection area.

[0023] The second gate 40 is provided between the inspection area and the second area. The second area is an area different from the first area and the inspection area. The second area may be an external area. The second gate 40 opens between the inspection area and the second area in response to the control of the control device 46, and guides the subject from the inspection area to the second area.

[0024] The inspection device 44 has an odor sensor 30. The inspection device 44 detects the odor of a specific metabolite in the subject or a specific object worn by the subject. Then, the inspection device 44 outputs odor data representing the odor of the specific metabolite or the specific object to the control device 46.

[0025] The specific metabolites are, for example, breath, saliva, sweat, etc. The specific object is a mask, etc. The odor sensor 30 detects odor substances emitted from the specific metabolites or the specific object, and generates odor data representing the odor.

[0026] The control device 46 controls the inspection area gate 34, the first gate 38, and the second gate 40. More specifically, when there is no person in the inspection area, the control device 46 controls the inspection area gate 34 to permit the subject to enter the inspection area from the external area, on condition that the subject has been authenticated by the management device 18.

[0027] The control device 46 also sends the odor data received from the inspection device 44 to the determination device 22, and obtains a determination result indicating whether the odor of the specific metabolite or specific object is a specific odor based on the odor data from the determination device 22. If the odor of the specific metabolite or specific object is not a specific odor, the control device 46 controls the first gate 38 to allow the subject to enter the first area. On the other hand, if the odor of the specific metabolite or specific object is a specific odor, the control device 46 controls the second gate 40 to guide the subject from the inspection area to the second area.

[0028] The determination device 22 receives odor data from the gate device 20. Based on the odor data, the determination device 22 uses a determination model generated in advance to determine whether the odor of a specific metabolite or a specific target is a specific odor. The determination device 22 then sends the determination result to the gate device 20. In this embodiment, the determination device 22 exchanges odor data and determination results with the gate device 20 via a network. Alternatively, the determination device 22 may be directly connected to the gate device 20 via a predetermined interface or the like, or may be incorporated inside the gate device 20.

[0029] Fig. 2 is a diagram showing a processing flow of the gate system 10. The gate system 10 performs processing on a subject according to the flow shown in Fig. 2 when there is no person in the inspection area.

[0030] First, in S11, the gate device 20 authenticates the subject before the subject enters the inspection area. If the subject is authenticated, in S12, the gate device 20 opens the inspection area gate 34. Then, in S13, the subject enters the inspection area from the external area. Then, in S14, the gate device 20 closes the inspection area gate 34. This allows the gate device 20 to shield the inspection area from the surroundings.

[0031] Next, in S15, the gate device 20 detects the odor of a specific metabolite of the subject or a specific object worn by the subject using the odor sensor 30 located in the inspection area. Next, in S16, the gate device 20 transmits odor data representing the odor of the specific metabolite or specific object to the determination device 22. Based on the received odor data, the determination device 22 uses a determination model generated in advance to determine whether the odor of the specific metabolite or specific object is a specific odor. Then, the determination device 22 transmits the determination result to the gate device 20.

[0032] Next, in S17, the gate device 20 receives the determination result from the determination device 22. Next, in S18, the gate device 20 opens one of the first gate 38 or the second gate 40 based on the determination result. Specifically, when the odor of the specific metabolite or specific target is not a specific odor, the gate device 20 opens the first gate 38 to allow the subject to enter the first area. Conversely, when the odor of the specific metabolite or specific target is a specific odor, the gate device 20 closes the first gate 38 and opens the second gate 40 to guide the subject to the second area.

[0033] Next, in S19, the subject leaves the inspection area and enters the first area or the second area. This leaves no people in the inspection area. Next, in S20, the gate device 20 closes the first gate 38 and the second gate 40. Then, the gate device 20 executes the processes from S11 to S20 again for the next new subject.

[0034] FIG. 3 is a diagram showing an example of the configuration of the odor sensor 30 and a process for generating a determination model.

[0035] The odor sensor 30 includes a plurality of sensor elements 50 (50-1, 52-2, 52-3, ..., 52-n). Each of the plurality of sensor elements 50 may be of any type. Each of the plurality of sensor elements 50 may be of any type, for example, a transducer type, a semiconductor type, an electrochemical type, or a film stress type. In addition, the plurality of sensor elements 50 may be configured to include sensor elements 50 of different types.

[0036] Each of the multiple sensor elements 50 selectively reacts to a specific type of odor component that is different from the others. The multiple sensor elements 50 may include two or more sensor elements 50 that selectively react to the same type of odor component. In this case, the two or more sensor elements 50 that selectively react to the same type of odor component may include sensor elements 50 with different sensitivities.

[0037] For example, if the sensor element 50 is an oscillator sensor, the sensor element 50 may have a different microstructure of the sensitive film or a different hydrophobicity or hydrophilicity from the other sensor elements 50. If the sensor element 50 is a semiconductor sensor, the sensor element 50 may have a different type of semiconductor as a parent phase or a different type and amount of supported metal used as a catalyst. This allows each of the multiple sensor elements 50 to selectively react to a specific type of odor component that is different from the others.

[0038] The odor data includes a plurality of detection values ​​representing the reaction results for each of the plurality of sensor elements 50. For example, the odor sensor 30 may output a plurality of time-series detection value data when an odor is detected for a certain period of time. In this case, the control device 46 may detect a feature amount from each of the plurality of time-series detection value data, calculate a set of the plurality of feature amounts, and output the calculated set of the plurality of feature amounts as odor data. For example, the control device 46 may calculate, as the feature amount, the difference between the maximum value and the minimum value in the certain period of time for each of the plurality of time-series detection value data. In addition, the control device 46 may calculate, as the feature amount, a value at a specific time in the certain period of time or an integrated value in the certain period of time for each of the plurality of time-series detection value data.

[0039] The judgment model is generated by machine learning using multiple teacher data. The multiple teacher data include correct answer data and incorrect answer data. The correct answer data includes a set of odor data representing the odor of a specific metabolite or specific object detected from a person suffering from a specific disease or infected with a specific virus, and labeling information representing a positive result. The incorrect answer data includes a set of odor data representing the odor of a specific metabolite or specific object detected from a person not suffering from a specific disease or infected with a specific virus, and labeling information representing a negative result. In this embodiment, the correct answer data includes a set of odor data representing the odor of a specific metabolite or specific object detected from a patient infected with COVID-19, and labeling information representing a positive result. The incorrect answer data includes a set of odor data representing the odor of a specific metabolite or specific object detected from a person not infected with COVID-19, and labeling information representing a negative result. This allows the judgment model to determine whether or not a subject has a specific disease or is infected with a specific virus, for example, whether or not the subject is infected with COVID-19.

[0040] The COVID-19 samples for generating the teacher data may be, for example, the breath or mask of a person who tested positive in a PCR test, and, for example, the breath or mask of a person who tested negative in a PCR test. Alternatively or in addition, the COVID-19 samples for generating the teacher data may be the breath or mask that the dog has determined to be positive and the breath or mask that the dog has determined to be negative, obtained by having a dog trained to detect COVID-19 infected people sniff out the smell of randomly obtained breath or masks.

[0041] The judgment model is, for example, a neural network, but may be another model that uses machine learning, such as a support vector machine.

[0042] For example, it is known that a person suffering from a certain disease or infected with a certain virus has a specific odor due to the odor emitted by a specific metabolite. For example, it is known that a person infected with a certain virus has a specific odor from their breath or sweat. For example, it is known that a person infected with COVID-19 has a specific odor from their breath.

[0043] Therefore, the gate system 10 configured as described above can permit subjects who are not suffering from a specific disease or who are not infected with a specific virus, such as subjects who are not infected with COVID-19, to enter the first area. The gate system 10 can also restrict subjects who are suffering from a specific disease or who are infected with a specific virus, such as subjects who are infected with COVID-19, from entering the first area.

[0044] In addition, when detecting the odor of a specific object such as a mask, the determination device 22 may further use a determination model that determines whether or not the odor of the specific object is the odor of the specific object in a state where the subject is not wearing the mask. In this case, the determination device 22 determines whether or not the odor of the specific object is a specific odor and whether or not the odor of the specific object in a state where the subject is not wearing the mask based on the determination model. In such a case, the control device 46 controls the first gate 38 to allow the subject to enter the first area when the odor of the specific object is not a specific odor and is not an odor in a state where the subject is not wearing the mask based on the determination result obtained from the determination device 22. In addition, the control device 46 controls the second gate 40 to lead the subject to the second area when the odor of the specific object is a specific odor or an odor in a state where the subject is not wearing the mask based on the determination result obtained from the determination device 22. This allows the gate system 10 to guide the subject to the second area, for example, if the subject puts on a mask immediately before entering the inspection area and the odor of the subject's breath is not on the mask.

[0045] Fig. 4 is a diagram showing a first example of the configuration of the inspection device 44. As an example, the inspection device 44 includes a bag providing device 72, a load lock chamber 74, a sensing chamber 76, an opening mechanism 78, an odor sensor 30, a disposal mechanism 80, a gas supplying device 82, and a spraying device 84, as shown in Fig. 4.

[0046] The bag providing device 72 provides the test bag 86 to the subject. The test bag 86 is a bag capable of sealingly storing the subject's breath or a specific object. When detecting the odor of a mask as the specific object, the test bag 86 is, for example, a bag with a fastener on one side. In this case, the subject receives the test bag 86 from the bag providing device 72, opens the fastener of the received test bag 86 by hand, stores the mask inside, and then closes the fastener. In this way, the test bag 86 can store the mask inside and be sealed. Also, when detecting the odor of the subject's breath, the test bag 86 is, for example, a bag having an injection tube. In this case, the injection tube can inject the breath exhaled by the subject from the mouth, and has a structure that does not allow the gas inside the test bag 86 to flow back, that is, a mechanism that does not allow the gas inside the test bag 86 to go out.

[0047] The test bag 86 containing the subject's breath or a specific object is placed inside the load lock chamber 74 by the subject. For example, the load lock chamber 74 has a door or lid that can be opened and closed by the subject located in the testing area, and the test bag 86 is placed inside with the door or lid open. After the test bag 86 is placed inside the load lock chamber 74, the door or lid is closed to shield the inside from the testing area. Then, the load lock chamber 74 transports the test bag 86 to the sensing chamber 76 in a state shielded from the testing area.

[0048] The sensing chamber 76 has a space therein. The sensing chamber 76 receives the test bag 86 transferred by the load lock chamber 74 from the load lock chamber 74 in a state in which the sensing chamber 76 is shielded from the external space. For example, the sensing chamber 76 has a shutter mechanism or the like between the sensing chamber 76 and the load lock chamber 74, and receives the test bag 86 with the shutter mechanism or the like open. After receiving the test bag 86 from the load lock chamber 74, the sensing chamber 76 closes the shutter mechanism or the like. As a result, the internal space of the sensing chamber 76 is shielded from the load lock chamber 74 and sealed.

[0049] The opening mechanism 78 is provided inside the sensing chamber 76. The opening mechanism 78 opens the test bag 86 after the test bag 86 is transported inside the sensing chamber 76 and the inside of the sensing chamber 76 is sealed. For example, the opening mechanism 78 may be a mechanism that cuts or tears the test bag 86.

[0050] The odor sensor 30 is provided inside the sensing chamber 76. The odor sensor 30 detects an odor when the test bag 86 is opened by the opening mechanism 78. The odor sensor 30 then outputs a plurality of detection values ​​representing the odor when the test bag 86 is opened. Note that the odor sensor 30 may output a plurality of time-series detection value data for a certain period of time after the test bag 86 is opened.

[0051] After an odor is detected by the odor sensor 30, the disposal mechanism 80 removes the test bag 86 from the sensing chamber 76. If a specific object such as a mask is stored in the test bag 86, the disposal mechanism 80 also removes the specific object such as the mask from the sensing chamber 76. The test bag 86 and the specific object such as the mask that have been removed from the sensing chamber 76 are discarded outside.

[0052] After the test bag 86 is removed from the sensing chamber 76, the gas supply device 82 supplies a reference gas for refreshing the odor sensor 30 into the inside of the sensing chamber 76 while the inside of the sensing chamber 76 is sealed. The reference gas is, for example, air or nitrogen. This allows the odor sensor 30 to detect the odor of a specific object such as a new breath or mask inside the test bag 86 without being affected by the odor of the specific object such as the previous breath or mask.

[0053] The spray device 84 supplies air and sprays a disinfectant into the testing area and inside the load lock chamber 74 while the sensing chamber 76 is shielded from the load lock chamber 74. For example, the spray device 84 sprays air and a disinfectant while the door or lid on the side of the testing area in the load lock chamber 74 is open. The disinfectant is, for example, a drug that inactivates a specific virus such as COVID-19 and has little effect on humans. For example, when detecting the odor of a specific metabolite of a patient infected with COVID-19, the disinfectant may be hypochlorous acid. This allows the spray device 84 to remove viruses in the testing area and inside the load lock chamber 74 to eliminate virus infection to other people, and not to affect the sensitive membrane of the odor sensor 30 in the sensing chamber 76. The spray device 84 may be provided as a part of the testing device 44, or may be provided in the gate device 20 separately from the testing device 44.

[0054] Fig. 5 is a diagram showing a process flow of the gate system 10 equipped with the inspection device 44 shown in Fig. 4. When the gate system 10 is equipped with the inspection device 44 shown in Fig. 4, it processes a subject according to the flow shown in Fig. 5.

[0055] First, in S31, the gate device 20 authenticates the subject before the subject enters the inspection area. If the subject is authenticated, in S32, the gate device 20 opens the inspection area gate 34. Then, in S33, the subject enters the inspection area from the external area. Then, in S34, the gate device 20 closes the inspection area gate 34.

[0056] Next, in S35, the gate apparatus 20 provides the test bag 86 to the subject. Next, in S36, the subject opens the fastener of the test bag 86, stores a mask inside, and then closes the fastener of the test bag 86. Alternatively, the subject may inject exhaled air into the test bag 86 via an injection tube.

[0057] Next, in S37, the subject opens the lid on the inspection area side of the load lock chamber 74. Next, in S38, the subject places the inspection bag 86 inside the load lock chamber 74. Next, in S39, the subject closes the lid on the inspection area side of the load lock chamber 74. This allows the gate device 20 to shield the inside of the load lock chamber 74 from the inspection area.

[0058] Next, in S40, the gate apparatus 20 opens the shutter mechanism to open the space between the load lock chamber 74 and the sensing chamber 76. Next, in S41, the gate apparatus 20 transports the test bag 86 from the load lock chamber 74 to the sensing chamber 76.

[0059] Next, in S42, the gate apparatus 20 closes the shutter mechanism to isolate the load lock chamber 74 from the sensing chamber 76. This enables the gate apparatus 20 to seal the inside of the sensing chamber 76.

[0060] Next, in S43, the gate device 20 opens the test bag 86 inside the sensing chamber 76. This enables the gate device 20 to detect the odor of the specific object, such as the breath or the mask, inside the test bag 86 with the odor sensor 30.

[0061] Next, in S44, the gate device 20 detects the odor of the subject's breath or mask, etc., using the odor sensor 30. Next, in S45, the gate device 20 transmits odor data to the determination device 22. Next, in S46, the gate device 20 receives a determination result from the determination device 22. Next, in S47, the gate device 20 opens either the first gate 38 or the second gate 40 based on the determination result. Next, in S48, the subject leaves the inspection area and enters the first area or the second area. As a result, there is no person in the inspection area. Next, in S49, the gate device 20 closes the first gate 38 and the second gate 40.

[0062] Next, in S50, the gate device 20 takes out the test bag 86 and the specific objects such as the mask inside the sensing chamber 76 to the outside, and discards the test bag 86 and the specific objects such as the mask. Next, in S51, the gate device 20 injects a reference gas such as air or nitrogen into the sensing chamber 76 to refresh the odor sensor 30. Next, in S52, the gate device 20 supplies air and sprays a disinfectant into the testing area and the inside of the load lock chamber 74 to disinfect the testing area and the inside of the load lock chamber 74.

[0063] Then, the gate device 20 executes the processes from S31 to S52 again for the next new target person.

[0064] The testing device 44 according to the first example can disinfect the testing area and the inside of the load lock chamber 74 without affecting the sensitive membrane of the odor sensor 30. Therefore, the testing device 44 configured as described above can safely and accurately detect the odor emitted by a specific metabolite or a specific target in a subject.

[0065] 6 is a diagram showing a second example of the configuration of the inspection device 44. As an example, the inspection device 44 may be configured to include a bag providing device 72, a sensing case 92, an odor sensor 30, a gas supplying device 82, and a spraying device 84.

[0066] The bag providing device 72 provides a test bag 86 to the subject. The test bag 86 has almost the same configuration as the first example shown in Fig. 6. However, the test bag 86 according to the second example further has a gas outlet 90 capable of discharging internal gas.

[0067] The sensing case 92 includes therein the odor sensor 30. The sensing case 92 also has a first gas inlet 94, a second gas inlet 96, a first pump 98, and a second pump 100.

[0068] For example, the sensing case 92 is attached to the shielding wall 32. The odor sensor 30 is provided in a space provided inside the sensing case 92.

[0069] The first gas inlet 94 can be connected to a gas outlet 90 provided in the inspection bag 86. When the first gas inlet 94 is connected to the gas outlet 90, the first gas inlet 94 can suck in gas discharged from the gas outlet 90. When the gas outlet 90 is not connected to the first gas inlet 94, the gas outlet 90 stops discharging gas from inside the inspection bag 86, and when connected to the first gas inlet 94, the gas outlet 90 allows gas to be discharged from inside the inspection bag 86.

[0070] The second gas inlet 96 is connected to the gas supply device 82 and allows the reference gas discharged from the gas supply device 82 to pass therethrough.

[0071] The first pump 98 draws in gas from the first gas inlet 94 and sends the drawn in gas to the internal space in which the odor sensor 30 is provided. In this way, the first pump 98 can send gas inside the test bag 86 to the internal space in which the odor sensor 30 is provided. The operation of the first pump 98 is controlled by, for example, the control device 46.

[0072] The second pump 100 sucks in gas from the second gas inlet 96 and sends the sucked gas to the internal space in which the odor sensor 30 is provided. In this way, the second pump 100 can send the reference gas discharged from the gas supply device 82 to the internal space in which the odor sensor 30 is provided. The operation of the first pump 98 is controlled by, for example, the control device 46.

[0073] In such a testing device 44, when the gas outlet 90 and the first gas inlet 94 are connected and the first pump 98 is operated, the odor sensor 30 detects an odor. This allows the odor sensor 30 to detect the odor of the subject's breath or a specific object inside the testing bag 86.

[0074] Moreover, in the testing device 44, after the gas outlet 90 is removed from the first gas inlet 94, the gas supply device 82 discharges the reference gas and the second pump 100 operates. This allows the testing device 44 to refresh the odor sensor 30 and detect the odor of the breath or specific object such as a mask inside a new testing bag 86 without being affected by the odor of the immediately previous breath or specific object such as a mask.

[0075] The spray device 84 supplies air and sprays a disinfectant to the testing area after the gas outlet 90 is removed from the first gas inlet 94. In this way, the spray device 84 can remove viruses from the testing area to prevent the virus from infecting other people, while not affecting the sensitive membrane of the odor sensor 30 in the sensing case 92.

[0076] Fig. 7 is a diagram showing a process flow of the gate system 10 equipped with the inspection device 44 shown in Fig. 6. When the gate device 20 is equipped with the inspection device 44 shown in Fig. 6, it processes a subject according to the flow shown in Fig. 7.

[0077] First, in S61, the gate device 20 authenticates the subject before the subject enters the inspection area. If the subject is authenticated, in S62, the gate device 20 opens the inspection area gate 34. Then, in S63, the subject enters the inspection area from the external area. Then, in S64, the gate device 20 closes the inspection area gate 34.

[0078] Next, in S65, the gate apparatus 20 provides the test bag 86 to the subject. Next, in S66, the subject opens the fastener of the test bag 86, stores a mask inside, and then closes the fastener of the test bag 86. Alternatively, the subject may inject exhaled air into the test bag 86 via an injection tube.

[0079] Next, in S67, the subject connects the gas outlet 90 of the test bag 86 to the first gas inlet 94 of the sensing case 92. This allows the subject to connect the test bag 86 to the sensing case 92.

[0080] Next, in S68, the gate device 20 operates the first pump 98 of the sensing case 92 for a certain period of time. This allows the first pump 98 of the gate device 20 to send the gas inside the test bag 86 to the internal space of the sensing case 92.

[0081] Next, in S69, the gate device 20 detects the odor of the subject's breath or the mask, etc., using the odor sensor 30. Next, in S70, the gate device 20 transmits the odor data to the determination device 22. Next, in S71, the gate device 20 receives the determination result from the determination device 22.

[0082] Next, in S72, the subject removes the test bag 86 from the sensing case 92 and discards the test bag 86. Note that the gate apparatus 20 may be configured to automatically discard the test bag 86 attached to the sensing case 92.

[0083] Next, in S73, the gate device 20 opens either the first gate 38 or the second gate 40 based on the determination result. Next, in S74, the subject leaves the inspection area and enters the first area or the second area. This leaves no people in the inspection area. Next, in S75, the gate device 20 closes the first gate 38 and the second gate 40.

[0084] Next, in S76, the gate device 20 operates the second pump 100 of the sensing case 92 for a certain period of time. Next, in S77, while the second pump 100 is operating, the gate device 20 operates the gas supply device 82 to inject a reference gas into the inside of the sensing case 92 to refresh the odor sensor 30. Next, in S78, the gate device 20 supplies air to the inspection area and sprays a disinfectant to disinfect the inspection area.

[0085] Then, the gate device 20 executes the processes from S61 to S78 again for the next new target person.

[0086] The testing device 44 according to the second example can disinfect the testing area without affecting the sensitive membrane of the odor sensor 30 in the sensing case 92. Therefore, the testing device 44 configured in this way can safely and accurately detect the odor emitted by a specific metabolite or a specific target in a subject.

[0087] FIG. 8 is a diagram showing a gate system 10 according to a modified example.

[0088] When the control device 46 controls the first gate 38 to permit the subject to enter the first area, the control device 46 may transmit the certificate information to the management device 18. That is, when the control device 46 determines that the odor emitted by the specific metabolite or specific object in the subject is not a specific odor, the control device 46 may transmit the certificate information to the management device 18. When the management device 18 receives the certificate information, the management device 18 stores the certificate information in association with the user information of the subject. In addition, the management device 18 transmits the certificate information to a user terminal device 110 such as a smartphone held by the subject.

[0089] Furthermore, in a modified example, a store or facility not equipped with a gate device 20 is provided with a determination information processing device 112. The determination information processing device 112 acquires certificate information output from a user terminal device 110 held by a subject, and judges whether the acquired certificate information is legitimate. For example, the determination information processing device 112 detects a two-dimensional code displayed on a monitor of the user terminal device 110, and judges whether the certificate information included in the detected two-dimensional code is legitimate. Also, for example, the determination information processing device 112 may acquire certificate information from the user terminal device 110 by wireless communication, and judge whether the acquired certificate information is legitimate. Then, if the certificate information is legitimate, the determination information processing device 112 permits the subject to enter a predetermined area in the store.

[0090] As a result, even in a store or facility where it is difficult to install a gate device 20, the gate system 10 can use the determination results from other gate devices 20 to determine whether to permit a subject to enter a predetermined area. Therefore, the gate system 10 can permit a subject who is not suffering from a specific disease or infected with a specific virus, for example, a subject who is not infected with COVID-19, to enter a predetermined area of ​​a store or facility that does not have a gate device 20. Furthermore, the gate system 10 can restrict a subject who is suffering from a specific disease or infected with a specific virus, for example, a subject who is infected with COVID-19, from entering the predetermined area.

[0091] Furthermore, the control device 46 may include date and time information indicating the date and time when the test was performed in the certificate information. In this case, the determination information processing device 112 can permit the subject to enter the specified area on the condition that the current date and time has not passed a certain period of time since the date and time information included in the certificate information. This allows the determination information processing device 112 to restrict the subject, who has passed through the gate device 20 for a certain period of time and is therefore likely to have a specific disease or be infected with a specific virus, from entering the specified area.

[0092] Although the embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. Various modifications can be made to the embodiments. [Explanation of symbols]
