[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-171105 Summary of the Invention [Problem to be solved by the invention]
[0004] However, at a service station that sells fuel oil, if the person filling the tank is trying to use a lighter or pour fuel into a container other than the vehicle's, refueling is not permitted. Therefore, service station staff visually check the situation before allowing the fuel to be dispensed from the fuel nozzle. This also applies to service stations that use self-service fueling systems. For this reason, even in service stations that use self-service fueling systems, it is necessary to have staff available to check the situation. However, in today's society where population imbalances are becoming more prevalent, maintaining a service station in sparsely populated areas is difficult due to the balance between the labor costs of hiring staff and fuel oil sales. However, in these areas, service stations are an essential piece of infrastructure, and there is a need to reduce the burden on staff at service stations.

[0066] According to the present invention, a fuel supply management system for a service station can be provided that reduces the workload of staff. [Brief explanation of the drawings]
[0067] [Figure 1] 1 is an overall configuration diagram of a fuel supply management system according to a first embodiment of the present invention; [Figure 2] FIG. 10 is an overall configuration diagram of a fuel supply management system according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0068] Hereinafter, embodiments of the present invention will be described with reference to the drawings. For the sake of convenience, the description of components having the same reference numerals as those already described in the description of the embodiments will be omitted.
[0069] (First embodiment) FIG. 1 shows an overall configuration diagram of a refueling control system 1A according to a first embodiment. As shown in FIG. 1, the refueling control system 1A includes a refueling machine 11 capable of supplying fuel oil from a tank 10, a camera 15 capable of monitoring a fuel filler 13 of a vehicle 12, the refueling machine 11, and a refueling person 14, an antenna 17 capable of detecting the radio wave intensity of a mobile phone 16, a display device 18 that displays information to the refueling person 14, and a control unit 19. The control unit 19 is communicatively connected to the refueling machine 11, the camera 15, the antenna 17, and the display device 18. The control unit 19 is connected to the refueling machine 11, the camera 15, the antenna 17, and the display device 18 via a wired or wireless connection. The refueling control system 1A can be used, for example, as a system installed in a service station that sells fuel oil and the like.
[0070] The refueling machine 11 is equipped with a switching valve 21. The switching valve 21 is provided midway through a pipeline 23 connecting the refueling nozzle 22 and the tank 10. The switching valve 21 is a valve that switches between an allowed state in which the discharge of fuel oil from the refueling nozzle 22 is permitted, and a disallowed state in which the discharge of fuel oil from the refueling nozzle 22 is not permitted. The switching valve 21 is a normally closed solenoid valve. When a permission signal is sent from the control unit 19 to the switching valve 21, the switching valve 21 opens to the allowed state. When a disallowance signal is sent from the control unit 19 to the switching valve 21, the switching valve 21 closes to the disallowed state. Note that when no signal is sent from the control unit 19, the switching valve 21 is closed to the disallowed state.
[0071] The fuel dispenser 11 is equipped with a fuel dispenser detection unit 24. The fuel dispenser detection unit 24 is capable of detecting the start of fuel dispenser by the fuel dispenser 14. The fuel dispenser detection unit detects the start of fuel dispenser by, for example, detecting that oil has started to flow in the pipeline 23, that the fuel dispenser meter of the fuel dispenser 11 is operating (rotating), or that the fuel dispenser lever provided on the fuel dispenser nozzle 22 is being operated (pulled). The fuel dispenser detection unit 24 may be configured, for example, with the camera 15 or various sensors.
[0072] The control unit 19 includes a determination unit 31 and a switching unit 32. The determination unit 31 determines whether or not to permit the discharge of fuel oil based on information acquired from the outside by the camera 15, the antenna 17, various sensors described below, and the like. The determination unit 31 outputs the determination result as to whether or not to permit the discharge of fuel oil to the switching unit 32. The switching unit 32 outputs, to the switching valve 21, a permission signal that permits the discharge of fuel oil or a non-permission signal that does not permit the discharge of fuel oil, depending on the determination result output from the determination unit 31. The determination unit 31 and the switching unit 32 may be configured as separate units or as a single unit.
[0073] (Static electricity removal: camera) The fuel tanker 11 is provided with a static eliminator 25. Because fuel vapor is likely to be generated at the fuel filler opening 13 of the vehicle 12 to be refueled, it is necessary to remove static electricity using the static eliminator 25 to prevent the fuel vapor from igniting due to a static spark. The static eliminator 25 includes, for example, a conductive contact portion provided at a position where the hand will come into contact, and a connection portion that electrically connects the contact portion to the ground (earth). When the fuel dispenser 14 touches the contact portion of the static eliminator 25 with their hand, the static electricity charged to the fuel dispenser 14 flows to the static eliminator 25 and is discharged to the ground via the connection portion. This removes static electricity from the fuel dispenser. Note that the static eliminator 25 does not necessarily have to be provided in the fuel tanker 11, and may be provided, for example, near the fuel tanker 11, where the fuel dispenser 14 can touch it before refueling.
[0074] The camera 15 is installed so as to be able to monitor one or more locations in the space where refueling operations are performed, including the refueling machine 11, the refueling person 14, and the vehicle 12. Therefore, the camera 15 is able to monitor the static eliminator 25 installed in the refueling machine 11. Images captured by the camera 15, including the static eliminator 25, are transmitted from the camera 15 to the control unit 19. The determination unit 31 of the control unit 19 analyzes and processes the images captured by the camera 15 to determine whether the refueling person 14 has touched the static eliminator 25 with their hand and whether the static eliminator 25 has eliminated the static electricity. For example, if the camera 15 is installed so as to capture images of the static eliminator 25 from the side, the determination unit 31 determines that the refueling person 14 has eliminated the static electricity with the static eliminator 25 when the distance between the contact portion of the static eliminator 25 and the hand of the refueling person 14 is less than a predetermined value.
[0075] For example, when the determination unit 31 determines that the static electricity charged on the fuel dispenser 14 has been removed by the static electricity eliminator 25, the determination unit 31 outputs a determination result permitting the discharge of fuel oil to the switching unit 32. The switching unit 32 outputs a permission signal permitting the discharge of fuel oil to the switching valve 21 in accordance with the determination result from the determination unit 31. The switching valve 21 switches to an open state allowing the discharge of fuel oil based on the permission signal output from the switching unit 32. In this way, the control unit 19 permits refueling by the refueling aircraft 11 after determining, based on the image acquired by the camera 15, that the fuel dispenser 14 has removed static electricity by the static electricity eliminator 25. Conversely, when the control unit 19 determines, based on the image acquired by the camera 15, that the fuel dispenser 14 has not removed static electricity by the static electricity eliminator 25, the control unit 19 does not permit refueling by the refueling aircraft 11.
[0076] According to this configuration, for example, the staff at the service station do not have to visually check whether the fuel dispenser 14 has removed static electricity with the static eliminator 25, and the decision as to whether or not to permit fuel dispense is automatically made, thereby reducing the workload of the staff.
[0077] (Static electricity removal: sensor) The static electricity eliminator 25 is equipped with a current sensor 26 (an example of a sensor) that can detect the flow of static electricity from the fuel dispenser 14. When the current sensor 26 detects that static electricity has flowed from the fuel dispenser 14 toward the contact or connection part of the static electricity eliminator 25 and that the static electricity of the fuel dispenser 14 has been eliminated, it transmits an elimination signal to the control unit 19 indicating that the static electricity has been eliminated.
[0078] When the determination unit 31 of the control unit 19 determines that it has received an elimination signal from the current sensor 26 indicating that the fuel dispenser 14 has removed static electricity, it outputs a determination result permitting the discharge of fuel oil to the switching unit 32. The switching unit 32 outputs an authorization signal permitting the discharge of fuel oil to the switching valve 21 in accordance with the determination result from the determination unit 31. In this way, the control unit 19 permits refueling by the refueling machine 11 after receiving an elimination signal indicating that the fuel dispenser 14 has removed static electricity from the current sensor 26. Conversely, the control unit 19 does not permit refueling by the refueling machine 11 while it has not received an elimination signal from the current sensor 26 indicating that the fuel dispenser 14 has removed static electricity. Note that the elimination signal indicating that static electricity has been removed may be input directly to the switching unit 32 without using the determination unit 31. The switching unit 32 may output an authorization signal permitting the discharge of fuel oil to the switching valve 21 based on the elimination signal indicating that static electricity has been removed.
[0079] According to this configuration, as in the case where the camera 15 is used, the staff does not have to visually check whether the fuel dispenser 14 has removed static electricity with the static eliminator 25. Furthermore, since permission or denial of fuel dispense is automatically determined and switched on, the workload of the staff can be reduced.
[0080] As a sensor capable of detecting the flow of static electricity from the fuel dispenser 14, a voltage sensor, a power sensor, or the like may be used in addition to a current sensor.
[0081] (Static electricity removal: display device) The display device 18 is provided in a location where it can be seen by a fuel supplier 14 who is about to refuel the vehicle 12. The display device 18 displays predetermined attention-grabbing information to the fuel supplier 14 based on a display signal output from the control unit 19.
[0082] When monitoring with the camera 15 or detecting with the current sensor 26, if the control unit 19 does not permit refueling by the refueling machine 11, it closes the switching valve 21 to prevent the discharge of fuel oil, and displays information on the display device 18 urging the refueling person 14 to remove static electricity with the static eliminator 25. The control unit 19 displays, for example, text such as "You have not touched the static eliminator yet. Please touch it," or a picture of a static eliminator on the display device 18.
[0083] In this manner, when refueling is denied, the display device 18 displays a message that the fuel dispenser 14 has not removed static electricity, thereby visually alerting the fuel dispenser 14 to the danger and reducing the workload of staff.
[0084] (Fuel nozzle: camera) As described above, the camera 15 is installed so as to be able to monitor the fuel filler opening 13 of the vehicle 12, the fuel dispenser 11, and the person dispensing fuel 14. Therefore, the camera 15 can monitor the fuel filler nozzle 22 provided in the fuel dispenser 11, and can also monitor the fuel filler nozzle 22 inserted into the fuel filler opening 13. Images captured by the camera 15, including the fuel filler nozzle 22, etc., are transmitted from the camera 15 to the control unit 19. The determination unit 31 of the control unit 19 analyzes and processes the images captured by the camera 15 to determine whether the fuel filler nozzle 22 is inserted into the fuel filler opening 13. For example, if the camera 15 is installed so as to capture an image of the fuel filler opening 13 from the side, the determination unit 31 determines that the fuel filler nozzle 22 is inserted into the fuel filler opening 13 when a predetermined length of the tip of the fuel filler nozzle 22 is hidden within the fuel filler opening 13.
[0085] For example, when the determination unit 31 determines that the fuel filler nozzle 22 is inserted into the fuel filler opening 13, it outputs a determination result permitting the discharge of fuel oil to the switching unit 32. The switching unit 32 outputs an permission signal permitting the discharge of fuel oil to the switching valve 21 in accordance with the determination result from the determination unit 31. As a result, the switching valve 21 switches to an open state in which the discharge of fuel oil is possible, based on the permission signal output from the switching unit 32. In this way, the control unit 19 permits refueling by the refueling machine 11 while it determines, based on the image acquired by the camera 15, that the refueling nozzle 22 is inserted into the fuel filler opening 13. Conversely, when the control unit 19 determines, based on the image acquired by the camera 15, that the refueling nozzle 22 is not inserted into the fuel filler opening 13, it does not permit refueling by the refueling machine 11.
[0086] The determination of whether the fuel nozzle 22 is inserted into the fuel filler opening 13 is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on images captured by the camera 15. After determining that the fuel nozzle 13 is not inserted and disallowing fueling by the fuel dispenser 11, if a subsequent determination determines that the fuel nozzle 13 is inserted, the control unit 19 permits fueling by the fuel dispenser 11.
[0087] (Before refueling) The refueling detection unit 24 detects whether the refueling person 14 has started refueling the fuel filler opening 13 of the vehicle 12, and transmits the detection result to the control unit 19. The control unit 19 does not permit refueling by the refueling machine 11 until a refueling detection signal indicating that refueling has started is input from the refueling detection unit 24, that is, until the refueling person 14 starts refueling. However, if the control unit 19 determines that the refueling nozzle 22 has been inserted into the refueling opening 13 based on an image captured by the camera 15, it determines that refueling is possible and permits refueling by the refueling machine 11.
[0088] (Refueling) The control unit 19 permits refueling by the refueling machine 11 until a refueling completion signal indicating that refueling has been completed is input from the refueling detection unit 24 after refueling has started, i.e., while the refueler 14 is refueling. However, if the control unit 19 determines based on an image captured by the camera 15 that the refueling nozzle 22 is not inserted into the refueling opening 13, the control unit 19 does not permit refueling by the refueling machine 11. For example, if the refueling nozzle 22 is removed from the refueling opening 13 while the refueling nozzle 22 is inserted into the refueling opening 13 and is being refueled, the control unit 19 determines that refueling is not possible and does not permit refueling by the refueling machine 11.
[0089] According to this configuration, for example, staff do not have to visually check whether the fuel nozzle 22 is inserted into the fuel filler opening 13, and the decision as to whether or not to permit fueling is made automatically, thereby reducing the workload of staff. Furthermore, by repeatedly determining at predetermined intervals whether the fuel nozzle 22 is inserted into the fuel filler opening 13, it is possible to accurately and automatically determine whether fueling is permitted or not depending on the state. Furthermore, before the start of refueling by the refueler 14 is detected, refueling by the refueling machine 11 is not permitted unless it is confirmed that the refueling nozzle 22 has been inserted into the refueling opening 13 and refueling is permitted, so that refueling can be accurately permitted or not permitted depending on the state. Furthermore, from the time when refueling by the refueler 14 starts until the end of refueling is detected, refueling by the refueling machine 11 is permitted unless, for example, it is detected that the refueling nozzle 22 is not inserted into the refueling opening 13 and refueling is not permitted, so refueling can be permitted or not permitted accurately depending on the situation.
[0090] (Fuel nozzle: sensor) An illuminance sensor 27 (an example of a sensor) is attached to the tip of the fuel filler nozzle 22 provided in the fuel dispenser 11. The illuminance sensor 27 is a sensor that can detect whether or not the fuel filler nozzle 22 is inserted into the fuel filler neck 13. For example, because the inside of the fuel filler neck 13 is darker than the outside of the fuel filler neck 13, the illuminance inside the fuel filler neck 13 measured by the illuminance sensor 27 is lower than a predetermined value, and it can be detected that the fuel filler nozzle 22 is inserted into the fuel filler neck 13. When the illuminance sensor 27 detects that the fuel filler nozzle 22 is inserted into the fuel filler neck 13, it transmits an insertion signal indicating this to the control unit 19. Furthermore, when the illuminance sensor 27 detects that the fuel filler nozzle 22 is not inserted into the fuel filler neck 13, it transmits a non-insertion signal indicating this to the control unit 19.
[0091] When the determination unit 31 of the control unit 19 determines that an insertion signal indicating that the fuel filler nozzle 22 is inserted into the fuel filler opening 13 has been input, it outputs a determination result permitting the discharge of fuel oil to the switching unit 32. The switching unit 32 outputs a permission signal permitting the discharge of fuel oil to the switching valve 21 in accordance with the determination result from the determination unit 31. Furthermore, when the determination unit 31 determines that a non-insertion signal indicating that the fuel filler nozzle 22 is not inserted into the fuel filler opening 13 has been input, it outputs a determination result prohibiting the discharge of fuel oil to the switching unit 32. The switching unit 32 outputs a prohibition signal prohibiting the discharge of fuel oil to the switching valve 21 in accordance with the determination result from the determination unit 31.
[0092] In this way, the control unit 19 permits refueling by the refueling machine 11 while an insertion signal indicating that the refueling nozzle 22 is inserted into the refueling opening 13 is input. On the other hand, the control unit 19 does not permit refueling by the refueling machine 11 when a non-insertion signal indicating that the refueling nozzle 22 is not inserted into the refueling opening 13 is input. Note that the determination by the determination unit 31 may be omitted, and the switching unit 32 may output a permission signal that permits or a non-permission signal that does not permit the discharge of fuel oil to the switching valve 21 based on the insertion signal and non-insertion signal output from the illuminance sensor 27.
[0093] The determination of whether the fuel nozzle 22 is inserted into the fuel filler opening 13 is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on the detection result of the illuminance sensor 27. After determining that the fuel nozzle 13 is not inserted and disallowing refueling by the fuel dispenser 11, if a subsequent determination determines that the fuel nozzle 13 is inserted, the control unit 19 permits refueling by the fuel dispenser 11.
[0094] (Before refueling) The control unit 19 does not permit refueling by the refueling machine 11 until a refueling detection signal indicating that refueling has started is input from the refueling detection unit 24, i.e., until refueling is started by the refueler 14. However, when an insertion signal indicating that the refueling nozzle 22 has been inserted into the refueling opening 13 is input from the illuminance sensor 27, the control unit 19 determines that refueling is possible and permits refueling by the refueling machine 11.
[0095] (Refueling) The control unit 19 permits refueling by the refueling machine 11 until a refueling completion signal indicating that refueling has been started and completed is input from the refueling detection unit 24, i.e., while the refueler 14 is refueling. However, if the control unit 19 receives a non-insertion signal indicating that the refueling nozzle 22 is not inserted into the refueling opening 13 from the illuminance sensor 27, the control unit 19 does not permit refueling by the refueling machine 11. For example, if the refueling nozzle 22 is inserted into the refueling opening 13 and is being refueled, and the illuminance measured by the illuminance sensor 27 becomes higher than a predetermined value, the control unit 19 determines that refueling is not possible and does not permit refueling by the refueling machine 11.
[0096] According to this configuration, as in the case where the camera 15 is used, permission or denial of refueling is automatically determined, thereby reducing the workload of the staff. Furthermore, by repeatedly determining at predetermined intervals whether the refueling nozzle 22 is inserted into the refueling opening 13, it is possible to accurately automatically determine whether refueling is permitted or not depending on the situation. Furthermore, permission or denial of refueling can be accurately switched depending on the situation between when the start of refueling by the refueler 14 is detected and when the end of refueling is detected.
[0097] (Fuel nozzle: display device) When monitoring with the camera 15 or detecting with the illuminance sensor 27, the control unit 19, when refueling by the refueling machine 11 is not permitted, closes the switching valve 21 to prevent the discharge of fuel oil, and displays information on the display device 18 urging the refueler 14 to insert the refueling nozzle 22 into the refueling opening 13. The control unit 19 displays, for example, text such as "Please insert the refueling nozzle into the refueling opening," or pictures of the refueling nozzle and the refueling opening on the display device 18.
[0098] According to this configuration, when refueling is denied, the display device 18 displays that the refueler 14 has not inserted the refueling nozzle 22 into the refueling opening 13, thereby visually alerting the refueler 14 to the danger and reducing the workload of staff.
[0099] (Source of fire: camera) As described above, the camera 15 is installed so as to be able to monitor the fuel filler 13 of the vehicle 12, the fuel dispenser 11, and the fuel dispenser 14. Therefore, the camera 15 can monitor whether the fuel dispenser 14 is using a fire source such as a lighter, cigarette, mobile phone, or Smartphone. Images captured by the camera 15, including the fuel dispenser 14, are transmitted from the camera 15 to the control unit 19. The determination unit 31 of the control unit 19 analyzes and processes the images captured by the camera 15 to determine whether the fuel dispenser 14 is using a fire source such as a lighter or cigarette. For example, the determination unit 31 determines whether the fuel dispenser 14 is using a fire source based on the brightness of the image captured by the camera 15. The determination unit 31 determines whether the fuel dispenser 14 is using a fire source when an area with a brightness higher than a certain value is detected around the mouth of the fuel dispenser 14. It should be noted that the determination is not limited to the area around the mouth of the fuel dispenser 14, and it may also be determined that the fuel dispenser 14 is using a lighter, cigarette, etc. when an area with a high brightness equal to or greater than a certain value is detected on the hand, such as the fingertips of the fuel dispenser 14. Furthermore, for example, when the fuel dispenser 14 has his / her hand close to his / her ear, the determination unit 31 may determine that the fuel dispenser 14 is using a mobile phone, etc.
[0100] For example, when the determination unit 31 determines that the fuel dispenser 14 is not using a lighter, cigarettes, or the like, it outputs a determination result permitting the discharge of fuel oil to the switching unit 32. The switching unit 32 outputs a permission signal permitting the discharge of fuel oil to the switching valve 21 in accordance with the determination result from the determination unit 31. As a result, the switching valve 21 switches to an open state allowing the discharge of fuel oil based on the permission signal output from the switching unit 32. In this way, the control unit 19 permits fuel dispense by the fuel dispenser 11 after determining, based on the image acquired by the camera 15, that the fuel dispenser 14 is not using a lighter, cigarettes, or the like. Conversely, when the control unit 19 determines, based on the image acquired by the camera 15, that the fuel dispenser 14 is using a lighter, cigarettes, or the like, it does not permit fuel dispense by the fuel dispenser 11.
[0101] The determination of whether the fuel dispenser 14 is using a fire source such as a lighter or cigarette is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on images captured by the camera 15. After the control unit 19 determines that the fuel dispenser 14 is using a lighter, cigarette, etc. and denies fuel dispenser 11 from dispensing fuel, if it subsequently determines that the fuel dispenser 14 is not using a lighter, cigarette, etc., the control unit 19 permits fuel dispenser 11 from dispensing fuel.
[0102] (Before refueling) The fuel dispensing detection unit 24 detects whether or not the fuel dispenser 14 has started dispensing fuel into the fuel filler opening 13 of the vehicle 12, and transmits the detection result to the control unit 19. The control unit 19 does not permit refueling by the fuel dispenser 11 until a refueling detection signal indicating that refueling has started is input from the fuel dispensing detection unit 24, that is, until the fuel dispenser 14 starts dispensing fuel. However, after the control unit 19 determines based on the image captured by the camera 15 that the fuel dispenser 14 is not using a lighter, cigarettes, etc., it determines that the vehicle is in a state where refueling is possible and permits refueling by the fuel dispenser 11.
[0103] (Refueling) The control unit 19 permits refueling by the refueling machine 11 from the start of refueling until a refueling completion signal indicating that refueling has ended is input from the refueling detection unit 24, i.e., while the refueler 14 is refueling. However, if the control unit 19 determines that the refueler 14 is using a lighter, cigarette, etc. based on an image captured by the camera 15, it will not permit refueling by the refueling machine 11. For example, if the refueler 14 lights a lighter or a cigarette while refueling, it will determine that refueling is not possible and will not permit refueling by the refueling machine 11.
[0104] (Fire source: display device) When monitoring with the camera 15, if the control unit 19 does not permit refueling by the refueling machine 11, it closes the switching valve 21 to prevent the discharge of fuel oil, and displays information on the display device 18 urging the refueling person 14 to stop using the fire source. For example, the control unit 19 displays on the display device 18 pictures, letters, etc. of fire sources such as a "lighter" or "cigarette."
[0105] According to this configuration, for example, staff do not need to visually check whether the fuel dispenser 14 is using a fire source such as a lighter or cigarette, and the decision to permit or deny fuel dispense is made automatically, thereby reducing the workload of the staff. Furthermore, by repeatedly determining whether the fuel dispenser 14 is using a lighter, cigarette, or other such ignition source at predetermined intervals, an automatic decision to permit or deny fuel dispense depending on the situation can be made accurately. Furthermore, before the start of fuel dispense by the fuel dispenser 14 is detected, fuel dispense by the fuel dispenser 11 is not permitted, allowing for accurate management of fuel. Furthermore, from the start of fuel dispense by the fuel dispenser 14 until the end of fuel dispense is detected, fuel dispense by the fuel dispenser 11 is permitted unless, for example, the fuel dispenser 14 is determined to be using a lighter, cigarette, or other such ignition source and refueling is denied. Therefore, fuel dispense can be accurately permitted or denied depending on the situation. Furthermore, when refueling is denied, the display device 18 displays that the fuel dispenser 14 is using a lighter, cigarette, or other such ignition source, thereby visually alerting the fuel dispenser 14 and reducing the workload of the staff.
[0106] (Mobile phone: sensor) Antenna 17 (an example of a sensor) capable of detecting the intensity of radio waves emitted from mobile phone 16 is provided, for example, near fuel tanker 11 so as to detect radio waves from mobile phone 16 carried by fuel dispenser 14. When antenna 17 detects radio waves emitted from mobile phone 16 of fuel dispenser 14, it transmits the radio wave intensity to control unit 19.
[0107] The determination unit 31 of the control unit 19 determines whether the radio wave intensity received from the antenna 17 is less than a predetermined value. If the determined radio wave intensity of the mobile phone 16 is less than the predetermined value, the determination unit 31 outputs a weak radio wave signal indicating this to the switching unit 32. If the determined radio wave intensity of the mobile phone 16 is equal to or greater than the predetermined value, the determination unit 31 determines that the fuel dispenser 14 is using the mobile phone 16 and outputs a strong radio wave signal indicating this to the switching unit 32. If the signal received from the determination unit 31 is a weak radio wave signal, the switching unit 32 outputs an authorization signal to the switching valve 21 that authorizes the discharge of fuel oil. If the signal received from the determination unit 31 is a strong radio wave signal, the switching unit 32 outputs a non-authorization signal to the switching valve 21 that prohibits the discharge of fuel oil. In this way, the control unit 19 permits refueling by the refueling machine 11 while the radio wave intensity detected by the antenna 17 is less than the predetermined value. On the other hand, the control unit 19 does not permit refueling by the refueling aircraft 11 while the radio wave intensity detected by the antenna 17 is equal to or greater than a predetermined value.
[0108] The determination of whether the radio wave strength received from antenna 17 is less than a predetermined value is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on the detection results of antenna 17. After determining that the radio wave strength of mobile phone 16 is equal to or greater than the predetermined value and disallowing refueling by refueling machine 11, if a subsequent determination determines that the radio wave strength of mobile phone 16 is less than the predetermined value, control unit 19 permits refueling by refueling machine 11.
[0109] (Before refueling) The control unit 19 does not permit refueling by the refueling machine 11 until a refueling detection signal indicating that refueling has started is input from the refueling detection unit 24, i.e., until refueling is started by the refueler 14. However, after the control unit 19 determines that the radio wave intensity received from the antenna 17 is less than a predetermined value, it determines that refueling is possible and permits refueling by the refueling machine 11.
[0110] (Refueling) The control unit 19 permits refueling by the refueling machine 11 from the refueling detection unit 24 after refueling has started until a refueling completion signal indicating that refueling has ended is input, i.e., while the refueling person 14 is refueling. However, if the control unit 19 determines that the radio wave strength received from the antenna 17 is equal to or greater than a predetermined value, it will not permit refueling by the refueling machine 11. For example, if the refueling person 14 starts using the mobile phone 16 while refueling and the radio wave strength received from the antenna 17 exceeds a predetermined value, it will determine that refueling is not possible and will not permit refueling by the refueling machine 11.
[0111] (Mobile phone: display device) When the control unit 19 detects this with the antenna 17 and does not permit refueling by the refueling machine 11, it closes the switching valve 21 to prevent the discharge of fuel oil, and displays information on the display device 18 urging the refueling person 14 to stop using the source of the radio waves. For example, the control unit 19 displays on the display device 18 a picture of a mobile phone or text such as "The use of mobile phones while refueling is prohibited."
[0112] According to this configuration, for example, staff do not need to visually check whether the fuel dispenser 14 is using the mobile phone 16, and the decision to permit or deny fuel dispense is made automatically, thereby reducing the workload of the staff. Furthermore, by repeatedly determining whether the fuel dispenser 14 is using the mobile phone 16 at predetermined intervals, an automatic decision to permit or deny fuel dispense can be made accurately depending on the situation. Furthermore, before the start of fuel dispense by the fuel dispenser 14 is detected, fuel dispense by the fuel dispenser 11 is not permitted, allowing for accurate management of fuel oil. Furthermore, from the start of fuel dispense by the fuel dispenser 14 until the end of the dispense is detected, fuel dispense by the fuel dispenser 11 is permitted unless, for example, the fuel dispenser 14 is determined to be using the mobile phone 16 and refueling is denied. Therefore, fuel dispense can be accurately permitted or denied depending on the situation. Furthermore, when refueling is denied, the fact that the fuel dispenser 14 is using the mobile phone 16 is displayed on the display device 18, thereby visually alerting the fuel dispenser 14 and reducing the workload of the staff.
[0113] (Space temperature: Thermosensor) The fuel tanker 11 is equipped with a thermal camera 28 (an example of a thermal sensor) that can measure the temperature of the space including the fuel tanker 14. The thermal camera 28 displays, for example, an image of the heat distribution of each part of the image of the fuel tanker 14, the fuel tanker 11, the fuel filler opening 13, the ground, etc. The thermal camera 28 transmits the measured temperature of the space (including the image of the heat distribution) to the control unit 19.
[0114] The determination unit 31 of the control unit 19 determines whether the space temperature received from the thermal camera 28 is below a predetermined temperature. If the determined temperature is below the predetermined temperature, the determination unit 31 outputs a low-temperature signal indicating this to the switching unit 32. If the determined temperature is equal to or higher than the predetermined temperature, the determination unit 31 outputs a high-temperature signal indicating this to the switching unit 32. If the signal received from the determination unit 31 is a low-temperature signal, the switching unit 32 outputs an enable signal to the switching valve 21 that enables the discharge of fuel oil. If the signal received from the determination unit 31 is a high-temperature signal, the switching unit 32 outputs a disable signal to the switching valve 21 that disables the discharge of fuel oil. In this way, the control unit 19 allows refueling by the refueling machine 11 while a thermal distribution image below the predetermined temperature is input from the thermal camera 28. On the other hand, the control unit 19 disables refueling by the refueling machine 11 when a thermal distribution image above the predetermined temperature is input from the thermal camera 28.
[0115] The determination of whether the temperature of the space received from the thermal camera 28 is below a predetermined temperature is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on the measurement results of the thermal camera 28. After the control unit 19 determines that the temperature of the space including the fuel dispenser 14 is above a predetermined value and denies fuel dispense by the fuel dispenser 11, if a subsequent determination determines that the temperature of the space is below the predetermined temperature, the control unit 19 permits fuel dispense by the fuel dispenser 11.
[0116] (Before refueling) The control unit 19 does not permit refueling by the refueling machine 11 until a refueling detection signal indicating that refueling has started is input from the refueling detection unit 24, i.e., until refueling is started by the refueler 14. However, after the control unit 19 determines that the temperature of the space received from the thermal camera 28 is below a predetermined temperature, it determines that refueling is possible and permits refueling by the refueling machine 11.
[0117] (Refueling) The control unit 19 permits refueling by the refueling machine 11 from the refueling detection unit 24 until a refueling completion signal indicating that refueling has been completed is input, i.e., while the refueling person 14 is refueling. However, if the control unit 19 determines that the temperature of the space received from the thermal camera 28 is equal to or higher than a predetermined value, the control unit 19 will not permit refueling by the refueling machine 11. For example, if the refueling person 14 uses a fire source such as a lighter or cigarette while refueling and the temperature of a part of the space exceeds a predetermined temperature, the control unit 19 determines that refueling is not possible and will not permit refueling by the refueling machine 11.
[0118] (Space temperature: display device) When the control unit 19 determines that refueling by the refueling machine 11 is not permitted in the case where measurement is made by the thermal camera 28, it closes the switching valve 21 to prevent the discharge of fuel oil, and displays information on the display device 18 urging the refueling person 14 to stop the action that is causing heat above a predetermined temperature or to stop using the device. The control unit 19 displays, for example, a distribution map of the thermal image acquired by the thermal camera 28 (thermogram) or the like on the display device 18.
[0119] According to this configuration, the temperature of the specified space can be measured by the thermal camera 28. This allows for an automatic decision to permit or deny refueling, similar to the case where a fire source such as a lighter or cigarette is monitored by the camera 15, thereby reducing the workload of staff. Furthermore, by repeatedly determining the temperature based on measurements by the thermal camera 28 at predetermined intervals, an automatic decision to permit or deny refueling can be accurately made depending on the situation. Furthermore, since refueling by the refueling machine 11 is not permitted before the start of refueling by the refueler 14 is detected, fuel oil can be managed accurately. Furthermore, from the start of refueling by the refueler 14 until its completion is detected, refueling by the refueling machine 11 is permitted unless, for example, the temperature of the space including the refueler 14 is determined to be above a predetermined temperature and refueling is denied. Therefore, refueling can be accurately permitted or denied depending on the situation. Furthermore, when refueling is denied, an image captured by the thermal camera 28 indicating that the temperature in the specified space is abnormally high is displayed on the display device 18. This visually alerts the refueler 14 and reduces the workload of staff.
[0120] Second Embodiment Fig. 2 shows an overall configuration diagram of a refueling control system 1B according to a second embodiment. As shown in Fig. 2, in addition to the configuration of the refueling control system 1A according to the first embodiment shown in Fig. 1, the refueling control system 1B includes a transmission device 52 capable of transmitting information to an observer (staff member) 51, and a permission device 53 (an example of a permission unit) capable of switching between permission and denial of refueling. The control unit 19 is communicatively connected to the refueling aircraft 11, the camera 15, the antenna 17, the display device 18, and the transmission device 52 via wired or wireless communication. The permission device 53 is communicatively connected to the switching valve 21 of the refueling aircraft 11 via wired or wireless communication.
[0121] The transmission device 52 is a device that transmits to the monitor 51 whether the refueling aircraft 11 is in a refueling permitted state or a refueling prohibited state. The transmission device 52 is installed, for example, in a staff room or the like that is away from the refueling aircraft 11. The transmission device 52 is composed of, for example, a display, a mobile terminal, a lamp, a buzzer, etc. In the case of a display and a mobile terminal, the refueling permitted state or the refueling prohibited state is transmitted, for example, by displaying text. In the case of a lamp, for example, the refueling permitted state is transmitted by lighting up "green" and the refueling prohibited state is transmitted by lighting up "red". Alternatively, the lamp may be configured to light up "red" when the refueling prohibited state is generated, and to be turned off when the refueling permitted state is generated. In the case of a buzzer, the refueling prohibited state is transmitted by sounding the buzzer.
[0122] The permission device 53 transmits a switching signal to the switching valve 21 to switch between permitting and disallowing refueling by the refueling aircraft 11. The permission device 53 is configured by, for example, a selector switch. The permission device 53 is a device operated by the monitor 51.
[0123] The control unit 19 is provided with a notification unit 33 in addition to the determination unit 31 and the switching unit 32. The notification unit 33 notifies the transmission device 52 of the determination result of the determination unit 31, i.e., the determination result as to whether the refueling machine 11 is in a refueling permitted state or a refueling prohibited state.
[0124] (Static electricity removal: camera) As in the first embodiment, the static eliminator 25 provided in the fuel tanker 11 can eliminate static electricity stored on the fuel tanker 14 when the fuel tanker 14 touches a contact portion. The camera 15 can also monitor the static eliminator 25 provided in the fuel tanker 11. The determination unit 31 of the control unit 19 determines whether the fuel tanker 14 has eliminated static electricity using the static eliminator 25, based on an image captured by the camera 15 that includes the static eliminator 25.
[0125] For example, when the determination unit 31 determines that the static electricity charged on the fuel dispenser 14 has been removed by the static eliminator 25, it outputs a determination result permitting the discharge of fuel oil to the notification unit 33. The notification unit 33 transmits a permission signal permitting the discharge of fuel oil to the transmission device 52 in accordance with the determination result from the determination unit 31. The transmission device 52 notifies the observer 51 that the discharge of fuel oil may be permitted, for example, by lighting a blue lamp, based on the permission signal transmitted from the notification unit 33. When the observer 51 sets, for example, a selector switch of the permission device 53 to the refueling permission side based on the transmitted information from the transmission device 52, a permission signal permitting the discharge of fuel oil is transmitted from the permission device 53 to the switching valve 21. Based on the permission signal transmitted from the permission device 53, the switching valve 21 opens, allowing the discharge of fuel oil.
[0126] In this way, after determining, based on the image acquired by the camera 15, that the fuel dispenser 14 has removed static electricity using the static eliminator 25, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling using the fuel tanker 11 is permitted. Conversely, after determining, based on the image acquired by the camera 15, that the fuel dispenser 14 has not removed static electricity using the static eliminator 25, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling using the fuel tanker 11 is not permitted, for example by turning on a red lamp. Furthermore, after determining, based on the image acquired by the camera 15, that it is impossible to determine whether the fuel dispenser 14 has removed static electricity using the static eliminator 25, the control unit 19 communicates to the monitor 51 via the transmission device 52 that the fuel dispenser 14 has removed static electricity using the static eliminator 25.
[0127] According to this configuration, whether or not the fuel dispenser 14 has removed static electricity with the static eliminator 25 can be notified to the supervisor (staff member) 51 via the transmission device 52. This means that the staff member does not need to monitor the behavior of the fuel dispenser 14, and can simply operate the permission device 53 based on the automatic determination of whether or not fuel dispense is permitted. This reduces the workload of the staff member.
[0128] In the above embodiment, the control unit 19 transmits permission or denial of refueling to the observer 51 via the transmission device 52, and the observer 51 switches the switching valve 21 by operating the permission device 53, but the present invention is not limited to this configuration. For example, the switching of the switching valve 21 may be automatically performed by the switching unit 32 of the control unit 19, as in the first embodiment. In this case, permission or denial of refueling is transmitted to the observer 51 via the transmission device 52, and the observer 51 can also reset the switching setting performed by the switching unit 32 of the control unit 19 by operating the permission device 53.
[0129] (Static electricity removal: sensor) The static electricity eliminator 25 is equipped with a current sensor 26. When the current sensor 26 detects that the static electricity of the fuel dispenser 14 has been eliminated, it transmits an elimination signal to the control unit 19 indicating this.
[0130] When the determination unit 31 of the control unit 19 determines that it has acquired a removal signal from the current sensor 26, it outputs a determination result permitting the discharge of fuel oil to the notification unit 33. The notification unit 33 transmits a permission signal permitting the discharge of fuel oil to the transmission device 52 in accordance with the determination result from the determination unit 31. Based on the permission signal from the notification unit 33, the transmission device 52 notifies the monitor 51 that the discharge of fuel oil may be permitted, for example, by lighting a blue lamp. When the monitor 51 sets, for example, a selector switch of the permission device 53 to the refueling permission side, a permission signal permitting the discharge of fuel oil is transmitted from the permission device 53 to the switching valve 21.
[0131] In this way, after the control unit 19 acquires from the current sensor 26 a removal signal indicating that the fuel dispenser 14 has removed static electricity, it notifies the monitor 51 via the transmission device 52 that refueling by the fuel dispenser 11 is permitted. Conversely to the above, while the control unit 19 has not acquired from the current sensor 26 a removal signal indicating that the fuel dispenser 14 has removed static electricity, it notifies the monitor 51 via the transmission device 52 that refueling by the fuel dispenser 11 is not permitted, for example by lighting a red lamp. The removal signal indicating that static electricity has been removed may be input directly to the notification unit 33, omitting the determination unit 31. The notification unit 33 may transmit a permission signal to the transmission device 52 to permit the discharge of fuel oil, based on the removal signal indicating that static electricity has been removed.
[0132] According to this configuration, similar to the case where the camera 15 is used, whether or not the static electricity of the fuel dispenser 14 has been removed can be notified to the supervisor (staff member) 51 via the transmission device 52. Therefore, the staff member only needs to operate the permission device 53 based on the automatic determination of whether or not fuel dispense is permitted, thereby reducing the workload of the staff member.
[0133] (Static electricity removal: display device) When monitoring with the camera 15 or detecting with the current sensor 26, the control unit 19 notifies the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted, and then causes the display device 18 to display information urging the refueler 14 to remove static electricity using the static eliminator 25.
[0134] In this manner, when the refueling denial is communicated to the supervisor 51, the display device 18 displays a message that the refueling person 14 has not removed static electricity, thereby visually alerting the refueling person 14 to the danger and reducing the workload of the staff.
[0135] (Fuel nozzle: camera) The camera 15 is capable of monitoring the fuel filler nozzle 22 provided in the fuel tanker 11, and is also capable of monitoring the fuel filler nozzle 22 being inserted into the fuel filler opening 13. An image captured by the camera 15, including the fuel filler nozzle 22, etc., is transmitted from the camera 15 to the control unit 19. The determination unit 31 of the control unit 19 analyzes and processes the image captured by the camera 15, and determines whether the fuel filler nozzle 22 is inserted into the fuel filler opening 13.
[0136] For example, when the determination unit 31 determines that the fuel nozzle 22 is inserted into the fuel filler opening 13, it outputs a determination result permitting the discharge of fuel oil to the notification unit 33. The notification unit 33 transmits a permission signal permitting the discharge of fuel oil to the transmission device 52 in accordance with the determination result from the determination unit 31. Based on the permission signal from the notification unit 33, the transmission device 52 notifies the observer 51 that the discharge of fuel oil may be permitted, for example, by lighting a blue lamp. When the observer 51 sets, for example, a selector switch of the permission device 53 to the refueling permission side, a permission signal permitting the discharge of fuel oil is transmitted from the permission device 53 to the switching valve 21.
[0137] In this way, when the control unit 19 determines, based on the image acquired by the camera 15, that the fuel nozzle 22 is inserted into the fuel filler opening 13, it notifies the monitor 51 via the transmission device 52 that refueling by the fuel tanker 11 is permitted. Conversely, when the control unit 19 determines, based on the image acquired by the camera 15, that the fuel nozzle 22 is not inserted into the fuel filler opening 13, it notifies the monitor 51 via the transmission device 52 that refueling by the fuel tanker 11 is not permitted, for example by lighting a red lamp.
[0138] The determination of whether the fuel nozzle 22 is inserted into the fuel filler opening 13 is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on images captured by the camera 15. If the control unit 19 determines that the fuel nozzle 13 is not inserted and notifies the observer 51 that refueling by the fuel tanker 11 is not permitted, and then if it subsequently determines that the fuel nozzle 13 is inserted, it notifies the observer 51 that refueling is permitted.
[0139] (Before refueling) The control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted until a refueling detection signal indicating that refueling has started is input from the refueling detection unit 24, i.e., until refueling by the refueler 14 has started. However, if the control unit 19 determines based on the image captured by the camera 15 that the refueling nozzle 22 has been inserted into the refueling opening 13, it communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is permitted.
[0140] (Refueling) After refueling has started and until a refueling completion signal indicating that refueling has ended is input from the refueling detection unit 24, i.e., while the refueler 14 is refueling, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is permitted. However, if the control unit 19 determines based on the image captured by the camera 15 that the refueling nozzle 22 is not inserted into the refueling opening 13, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted. For example, if the refueling nozzle 22 is inserted into the refueling opening 13 and then removed from the refueling opening 13 while refueling is being performed, the control unit 19 determines that refueling is not permitted, and communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted.
[0141] According to this configuration, the supervisor (staff member) 51 can be notified via the transmission device 52 whether refueling is permitted or not depending on whether the fuel nozzle 22 is inserted into the fuel filler opening 13. Therefore, the staff member does not need to monitor the refueling situation, but can simply operate the permission device 53 based on the automatic determination of whether refueling is permitted or not. This reduces the workload of the staff member. Furthermore, by repeatedly determining whether the fuel nozzle 22 is inserted into the fuel filler opening 13 at predetermined intervals, the supervisor 51 can be accurately notified whether refueling is permitted or not depending on the situation. Furthermore, before the start of refueling by the refueler 14 is detected, the supervisor 51 is notified via the transmission device 52 that refueling by the refueling machine 11 is not permitted except when it is confirmed that the fuel nozzle 22 is inserted into the fuel filler opening 13 and the supervisor 51 is permitted to refuel. Therefore, the supervisor 51 can be accurately notified whether refueling is permitted or not depending on the situation. Furthermore, from the time when refueling by the refueler 14 begins until its completion is detected, unless, for example, it is detected that the refueling nozzle 22 is not inserted into the refueling opening 13 and the monitor 51 is not permitted to refuel using the refueling machine 11, the monitor 51 is notified via the transmission device 52 that refueling using the refueling machine 11 is permitted, so that it is possible to accurately communicate whether refueling is permitted or not depending on the situation.
[0142] (Fuel nozzle: sensor) The illuminance sensor 27 detects whether or not the fuel filler nozzle 22 is inserted into the fuel filler neck 13. When the illuminance sensor 27 detects that the fuel filler nozzle 22 is inserted into the fuel filler neck 13, it transmits an insertion signal indicating this to the control unit 19. Furthermore, when the illuminance sensor 27 detects that the fuel filler nozzle 22 is not inserted into the fuel filler neck 13, it transmits a non-insertion signal indicating this to the control unit 19.
[0143] When the determination unit 31 of the control unit 19 determines that an insertion signal indicating that the fuel filler nozzle 22 is inserted into the fuel filler opening 13 has been input, it outputs a determination result permitting the discharge of fuel oil to the notification unit 33. The notification unit 33 transmits a permission signal permitting the discharge of fuel oil to the transmission device 52 in accordance with the determination result from the determination unit 31. Furthermore, when the determination unit 31 determines that a non-insertion signal indicating that the fuel filler nozzle 22 is not inserted into the fuel filler opening 13 has been input, it outputs a determination result prohibiting the discharge of fuel oil to the notification unit 33. The notification unit 33 transmits a prohibition signal prohibiting the discharge of fuel oil to the transmission device 52 in accordance with the determination result from the determination unit 31. The operation of the transmission device 52 and the permission device 53 is the same as when the fuel filler nozzle 22 is monitored by the camera 15.
[0144] In this way, when an insertion signal indicating that the fuel filler nozzle 22 is inserted into the fuel filler opening 13 is input, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the fuel filler 11 is permitted. Conversely, when a non-insertion signal indicating that the fuel filler nozzle 22 is not inserted into the fuel filler opening 13 is input, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the fuel filler 11 is not permitted. Note that the determination by the determination unit 31 may be omitted, and the notification unit 33 may output a permission signal that permits or a non-permission signal that does not permit the discharge of fuel oil to the transmission device 52 based on the insertion signal and non-insertion signal output from the illuminance sensor 27.
[0145] The determination of whether the fuel nozzle 22 is inserted into the fuel filler opening 13 is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on the detection result of the illuminance sensor 27. After the control unit 19 determines that the fuel nozzle 13 is not inserted and notifies the observer 51 that refueling by the fuel dispenser 11 is not permitted, if a subsequent determination determines that the fuel nozzle 13 is inserted, the control unit 19 notifies the observer 51 that refueling is permitted.
[0146] (Before refueling) The control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted until a refueling detection signal indicating that refueling has started is input from the refueling detection unit 24, i.e., until refueling by the refueler 14 has started. However, when an insertion signal indicating that the refueling nozzle 22 has been inserted into the refueling opening 13 is input from the illuminance sensor 27, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is permitted.
[0147] (Refueling) After refueling has started and until a refueling completion signal indicating that refueling has ended is input from the refueling detection unit 24, i.e., while the refueler 14 is refueling, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is permitted. However, if a non-insertion signal indicating that the refueling nozzle 22 is not inserted into the refueling opening 13 is input from the illuminance sensor 27, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted. For example, if the refueling nozzle 22 is inserted into the refueling opening 13 and then removed from the refueling opening 13 while refueling is being performed, the control unit 19 determines that refueling is not permitted and communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted.
[0148] According to this configuration, similar to the case where the camera 15 is used, the staff member is notified via the transmission device 52 whether refueling is permitted or not depending on whether the fuel nozzle 22 is inserted into the fuel filler opening 13. Therefore, the staff member only needs to operate the permission device 53 based on the automatic determination of whether refueling is permitted or not. This reduces the staff member's workload. Furthermore, by repeatedly determining whether the fuel nozzle 22 is inserted into the fuel filler opening 13, it is possible to accurately notify the monitor 51 whether refueling is permitted or not depending on the status. Furthermore, whether refueling is permitted or not depending on the status is notified to the staff member via the transmission device 52 both before the start of refueling by the refueler 14 is detected and until the end of refueling is detected, so that refueling can be accurately permitted or not depending on the status.
[0149] (Fuel nozzle: display device) When monitoring with the camera 15 or detecting with the current sensor 26, the control unit 19 notifies the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted, and then causes the display device 18 to display information urging the refueler 14 to insert the refueling nozzle 22 into the refueling opening 13.
[0150] In this manner, when the fact that refueling is not permitted is communicated to the monitor 51, the display device 18 displays that the refueler 14 has not inserted the refueling nozzle 22 into the refueling opening 13, thereby visually alerting the refueler 14 to the danger and reducing the workload of the staff.
[0151] (Source of fire: camera) The determination unit 31 of the control unit 19 analyzes and processes the image captured by the camera 15 to determine whether the fuel dispenser 14 is using a fire source such as a lighter, cigarette, or mobile phone 16. For example, the determination unit 31 determines whether the fuel dispenser 14 is using a fire source based on the brightness of the image captured by the camera 15. When an area with a brightness higher than a certain value is detected around the mouth of the fuel dispenser 14, the determination unit 31 determines that the fuel dispenser 14 is using a lighter, cigarette, or the like.
[0152] For example, if the determination unit 31 determines that the fuel dispenser 14 is not using a lighter, cigarettes, or the like, it outputs a determination result permitting the discharge of fuel oil to the notification unit 33. The notification unit 33 transmits a permission signal permitting the discharge of fuel oil to the transmission device 52 in accordance with the determination result from the determination unit 31. Furthermore, if the determination unit 31 determines that the fuel dispenser 14 is using a lighter, cigarettes, or the like, it outputs a determination result prohibiting the discharge of fuel oil to the notification unit 33. The notification unit 33 transmits a prohibition signal prohibiting the discharge of fuel oil to the transmission device 52 in accordance with the determination result from the determination unit 31. The operation of the transmission device 52 and the permission device 53 is the same as when monitoring the fuel nozzle 22 described above.
[0153] In this way, after determining based on the image acquired by the camera 15 that the fuel dispenser 14 is not using a lighter, cigarettes, etc., the control unit 19 notifies the monitor 51 via the transmission device 52 that fuel dispenser 14 is permitted to dispense fuel using the fuel dispenser 11. Conversely, when the control unit 19 determines based on the image acquired by the camera 15 that the fuel dispenser 14 is using a lighter, cigarettes, etc., the control unit 19 notifies the monitor 51 via the transmission device 52 that fuel dispenser 14 is not permitted to dispense fuel using the fuel dispenser 11.
[0154] The determination of whether the fuel dispenser 14 is using a fire source such as a lighter, cigarette, or portable terminal 16 is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on images captured by the camera 15. After determining that the fuel dispenser 14 is using a lighter, cigarette, portable terminal 16, etc. and informing the monitor 51 that fuel dispenser 11 is not permitted to dispense fuel, if a subsequent determination determines that the fuel dispenser 14 is not using a lighter, cigarette, portable terminal 16, etc., the control unit 19 informs the monitor 51 that fuel dispenser 14 is permitted to dispense fuel.
[0155] (Before refueling) The control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted until a refueling detection signal indicating that refueling has started is input from the refueling detection unit 24, i.e., until the refueling person 14 starts refueling. However, after the control unit 19 determines based on the image captured by the camera 15 that the refueling person 14 is not using a lighter, cigarettes, etc., it communicates to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is permitted.
[0156] (Refueling) After refueling has started and until a refueling completion signal indicating that refueling has ended is input from the refueling detection unit 24, i.e., while the refueler 14 is refueling, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling using the refueling machine 11 is permitted. However, if the control unit 19 determines, based on the image captured by the camera 15, that the refueler 14 is using a lighter, cigarette, or the like, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling using the refueling machine 11 is not permitted. For example, if the refueler 14 lights a lighter or a cigarette while refueling, the control unit 19 determines that refueling is not permitted, and communicates to the monitor 51 via the transmission device 52 that refueling using the refueling machine 11 is not permitted.
[0157] (Fire source: display device) When monitoring with the camera 15, the control unit 19 notifies the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted, and then causes the display device 18 to display information urging the refueler 14 to stop using the fire source. For example, the control unit 19 causes the display device 18 to display pictures, letters, etc. of fire sources such as a "lighter" or "cigarette."
[0158] According to this configuration, for example, whether refueling is permitted or not is notified to the staff via the transmission device 52 depending on whether the refueling person 14 is using a fire source such as a lighter or cigarette. Therefore, the staff only needs to operate the permission device 53 based on the automatic determination of whether refueling is permitted or not. This reduces the workload of the staff. Furthermore, by repeatedly determining at predetermined intervals whether the refueling person 14 is using a lighter, cigarette, etc., the automatic determination of whether refueling is permitted or not can be made accurately depending on the situation. Furthermore, before the start of refueling by the refueling person 14 is detected, the fact that refueling by the refueling machine 11 is not permitted is transmitted to the monitor 51 via the transmission device 52, allowing for accurate management of fuel oil. Furthermore, from the time when refueling by the refueling person 14 begins until the end of refueling is detected, unless it is determined that the refueling person 14 is using a lighter, cigarettes, etc. and a notice is sent to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted, the notice is sent to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is permitted, so that permission or denial of refueling can be accurately communicated according to the situation. Furthermore, when a notice is sent to the monitor 51 that refueling is not permitted, the display device 18 shows that the refueling person 14 is using a lighter, cigarettes, etc., so that the refueling person 14 can be visually warned and the workload of the staff can be reduced.
[0159] (Mobile phone: sensor) When the antenna 17 detects radio waves emitted from the mobile phone 16 of the fuel dispenser 14 , it transmits the intensity of the radio waves to the control unit 19 .
[0160] The determination unit 31 of the control unit 19 determines whether the radio wave intensity received from the antenna 17 is less than a predetermined value. If the determined radio wave intensity of the mobile phone 16 is less than the predetermined value, the determination unit 31 outputs a weak radio wave signal indicating this to the notification unit 33. If the determined radio wave intensity of the mobile phone 16 is equal to or greater than the predetermined value, the determination unit 31 determines that the fuel dispenser 14 is using the mobile phone 16 and outputs a strong radio wave signal indicating this to the notification unit 33. If the signal received from the determination unit 31 is a weak radio wave signal, the notification unit 33 transmits an authorization signal to the transmission device 52 that authorizes the discharge of fuel oil. If the signal received from the determination unit 31 is a strong radio wave signal, the notification unit 33 transmits a non-authorization signal to the transmission device 52 that prohibits the discharge of fuel oil. The operation of the transmission device 52 and the authorization device 53 is the same as when detecting the fuel nozzle 22 described above.
[0161] In this way, while the radio wave strength detected by the antenna 17 is below a predetermined value, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is permitted. On the other hand, while the radio wave strength detected by the antenna 17 is equal to or greater than a predetermined value, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is not permitted.
[0162] The determination of whether the radio wave strength received from antenna 17 is less than a predetermined value is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on the detection results of antenna 17. After determining that the radio wave strength of mobile phone 16 is equal to or greater than the predetermined value and informing monitor 51 that refueling by refueling aircraft 11 is not permitted, if a subsequent determination determines that the radio wave strength of mobile phone 16 is less than the predetermined value, control unit 19 informs monitor 51 that refueling is permitted.
[0163] (Before refueling) The control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is not permitted until a refueling detection signal indicating that refueling has started is input from the refueling detection unit 24, i.e., until refueling by the refueler 14 has started. However, after the control unit 19 determines that the radio wave strength received from the antenna 17 is below a predetermined value, it communicates to the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is permitted.
[0164] (Refueling) After refueling has started and until a refueling completion signal indicating that refueling has ended is input from the refueling detection unit 24, i.e., while the refueler 14 is refueling, the control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is permitted. However, if the control unit 19 determines that the radio wave strength received from the antenna 17 is equal to or greater than a predetermined value, it communicates to the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is not permitted. For example, if the refueler 14 starts using the mobile phone 16 while refueling and the radio wave strength received from the antenna 17 becomes equal to or greater than a predetermined value, it determines that refueling is not permitted and communicates to the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is not permitted.
[0165] (Mobile phone: display device) When the control unit 19 detects a signal using the antenna 17, it notifies the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is not permitted, and causes the display device 18 to display information urging the refueler 14 to stop using the source of the radio waves. For example, the control unit 19 causes the display device 18 to display a picture of a mobile phone or text such as "The use of mobile phones while refueling is prohibited."
[0166] According to this configuration, for example, whether or not refueling is permitted is notified to staff via the transmission device 52 depending on whether or not the refueling person 14 is using the mobile phone 16. Therefore, the staff only needs to operate the permission device 53 based on the automatic determination of whether or not refueling is permitted. This reduces the workload of the staff. Furthermore, by repeatedly determining at predetermined intervals whether or not the refueling person 14 is using the mobile phone 16, an automatic determination of whether or not refueling is permitted depending on the situation can be made accurately. Furthermore, before the start of refueling by the refueling person 14 is detected, the fact that refueling by the refueling machine 11 is not permitted is transmitted to the monitor 51 via the transmission device 52, allowing for accurate management of fuel oil. Furthermore, from the time when refueling by the refueler 14 begins until the end of refueling is detected, unless it is determined that the refueler 14 is using the mobile phone 16 and a notice is sent to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted, the notice is sent to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is permitted, so that permission or denial of refueling can be accurately communicated according to the situation. Furthermore, when a notice is sent to the monitor 51 that refueling is not permitted, the fact that the refueler 14 is using the mobile phone 16 is displayed on the display device 18, so that the refueler 14 can be visually warned and the workload of the staff can be reduced.
[0167] (Space temperature: Thermosensor) The thermal camera 28 measures the temperature of the space including the fuel dispenser 14 and transmits the measured temperature (including an image of the heat distribution) to the control unit 19.
[0168] The determination unit 31 of the control unit 19 determines whether the temperature of the space received from the thermal camera 28 is below a predetermined temperature. If the determined temperature is below the predetermined temperature, the determination unit 31 outputs a low-temperature signal indicating this to the notification unit 33. If the determined temperature is equal to or higher than the predetermined temperature, the determination unit 31 outputs a high-temperature signal indicating this to the notification unit 33. If the signal received from the determination unit 31 is a low-temperature signal, the notification unit 33 transmits an permission signal to the transmission device 52 that permits the discharge of fuel oil. If the signal received from the determination unit 31 is a high-temperature signal, the notification unit 33 transmits a non-permission signal to the transmission device 52 that prohibits the discharge of fuel oil. The operation of the transmission device 52 and the permission device 53 is the same as when detecting the fuel nozzle 22 described above.
[0169] In this way, while a thermal distribution image below a predetermined temperature is input from the thermal camera 28, the control unit 19 communicates to the monitor 51 via the communication device 52 that refueling by the refueling aircraft 11 is permitted. On the other hand, when a thermal distribution image above a predetermined temperature is input from the thermal camera 28, the control unit 19 communicates to the monitor 51 via the communication device 52 that refueling by the refueling aircraft 11 is not permitted.
[0170] The determination of whether the temperature of the space received from the thermal camera 28 is below a predetermined temperature is made at predetermined intervals (for example, every 0.5 seconds, 1 second, 3 seconds, etc.) based on the measurement results of the thermal camera 28. After the control unit 19 determines that the temperature of the space including the refueling person 14 is above a predetermined value and notifies the monitor 51 that refueling by the refueling machine 11 is not permitted, if a subsequent determination determines that the temperature of the space is below the predetermined temperature, the control unit 19 notifies the monitor 51 that refueling is permitted.
[0171] (Before refueling) The control unit 19 communicates to the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is not permitted until a refueling detection signal indicating that refueling has started is input from the refueling detection unit 24, i.e., until refueling by the refueler 14 has started. However, after the control unit 19 determines that the temperature of the space received from the thermal camera 28 is below a predetermined temperature, it communicates to the monitor 51 via the transmission device 52 that refueling by the refueling aircraft 11 is permitted.
[0172] (Refueling) After refueling has started and until a refueling completion signal indicating that refueling has ended is input from the refueling detection unit 24, i.e., while the refueler 14 is refueling, the control unit 19 transmits to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is permitted. However, if the control unit 19 determines that the temperature of the space received from the thermal camera 28 is equal to or higher than a predetermined value, the control unit 19 transmits to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted. For example, if the refueler 14 uses a fire source such as a lighter or cigarette while refueling and the temperature of a part of the space becomes equal to or higher than a predetermined temperature, the control unit 19 determines that refueling is not permitted and transmits to the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted.
[0173] (Space temperature: display device) When measuring with the thermal camera 28, the control unit 19 notifies the monitor 51 via the transmission device 52 that refueling by the refueling machine 11 is not permitted, and causes the display device 18 to display information urging the refueling person 14 to stop the action that is causing heat above a predetermined temperature or to stop using the device. The control unit 19 causes the display device 18 to display, for example, a distribution map of the thermal image acquired by the thermal camera 28 (thermogram) or the like.
[0174] According to this configuration, the temperature of the specified space can be measured by the thermal camera 28. Similar to the case where a fire source such as a lighter or cigarette is monitored by the camera 15, the staff member is notified via the transmission device 52 whether or not the fuel dispenser 14 is using a lighter, cigarette, or the like. Therefore, the staff member only needs to operate the permission device 53 based on the automatic determination of whether or not the fuel dispenser is permitted. This reduces the workload of the staff member. Furthermore, by repeatedly determining the temperature based on the measurements by the thermal camera 28 at predetermined intervals, the automatic determination of whether or not the fuel dispenser is permitted depending on the situation can be accurately performed. Furthermore, before the start of fuel dispenser 14 by the fuel dispenser 11 is detected, the fact that the fuel dispenser 11 is not permitted to dispense fuel is transmitted to the monitor 51 via the transmission device 52, enabling accurate management of fuel oil. Furthermore, from the time when refueling by the refueler 14 begins until its completion is detected, unless, for example, the temperature of the space including the refueler 14 is determined to be above a predetermined temperature and refueling by the refueling machine 11 is not permitted and the monitor 51 is notified via the transmission device 52 that refueling by the refueling machine 11 is permitted, the monitor 51 is notified via the transmission device 52 that refueling is permitted, so that permission or denial of refueling can be accurately communicated according to the situation. Furthermore, when refueling is not permitted to the monitor 51, an image captured by the thermal camera 28 indicating that the temperature in the predetermined space is abnormally high is displayed on the display device 18, so that the refueler 14 can be visually warned and the workload of the staff can be reduced.
[0175] In the above explanation, an example has been given in which a single camera is used to monitor each checkpoint (fuel filler, fuel pump, fuel dispenser, fuel nozzle, etc.), but for example, a configuration in which each point is monitored separately by multiple cameras may also be used. Also, multiple cameras may be used to monitor each checkpoint from multiple different angles. Antennas may also be provided in multiple locations. An illuminance sensor may also be provided in a location other than the fuel filler nozzle (for example, on the vehicle side (fuel filler)). The illuminance sensor is not limited to an illuminance sensor, and other sensors may also be used.
[0176] Although the embodiments of the present invention have been described above, it goes without saying that the technical scope of the present invention should not be construed as being limited by the description of the present embodiments. The present embodiments are merely examples, and it will be understood by those skilled in the art that various modifications of the embodiments are possible within the scope of the invention described in the claims. The technical scope of the present invention should be determined based on the scope of the invention described in the claims and its equivalents. [Explanation of symbols]
