Description

  The present disclosure relates to a fuel supply device that supplies fuel to a fuel tank or the like of a vehicle.

  Conventionally, as an example of a fuel supply station where a fuel supply device is installed, there is a self-service type gas station. In a self-service type gas station, a customer himself operates a fuel nozzle provided in a meter (fuel supply device) to perform a fueling operation on a fuel tank of a vehicle.

  On the other hand, there are increasing opportunities for fuel such as gasoline and light oil to be carried in fuel tanks other than vehicles such as carrying cans due to driving engine equipment, vehicle emergency fuel, and the like. However, for safety reasons, such as when fuel flows (e.g., shakes the container violently), it tends to generate static electricity, and its vapor is heavier than air, so it tends to accumulate in the recess. The refueling staff are responsible for refueling the fuel cans.

JP 2010-241469 A

  However, in a self-service type gas station, there is a possibility that the customer may operate the fuel nozzle provided in the metering machine without himself or herself and try to fuel the carrying can.

  For this reason, at a self-service filling station, for the sake of safety, the filling station staff must carefully monitor what the customer is trying to refuel, and try to refuel the carrying can. If this is the case, refueling work must not be allowed.

  In particular, there are cases where the refueling of gasoline or light oil to a carrying can as an emergency fuel for a vehicle is performed by the customer along with the refueling operation to the fuel tank of the vehicle. Even after refueling is permitted, until the refueling nozzle is housed in the weighing machine and the refueling operation is completed, the filling station staff will be careful not to change the refueling target from the fuel tank of the vehicle to the carrying can. There was a need to monitor.

  As a result, at the self-service refueling station, the customer's own refueling work, taking care not to operate the refueling nozzle on the weighing machine and refuel the carrying can. Monitoring was a heavy burden for gas station staff.

  The present disclosure has been made in view of the above-described problems, and is suitable for being applied to a self-service fuel supply station. It is an object of the present invention to provide a fuel supply device that reduces the burden on a fuel supply station staff member who monitors whether there is any abnormality or error in the fuel supply operation performed by the above.

  In order to solve the above-described problem, a fuel supply device according to the present disclosure includes a nozzle connected to a fuel supply port to be supplied with fuel during a fuel supply operation, and a nozzle storage portion in which the nozzle is stored during a non-fuel supply operation. And a nozzle detector that is provided in the nozzle storage portion and detects a storage / non-storage state of the nozzle with respect to the nozzle storage portion, and a fuel supply path that supplies fuel to the nozzle, A fuel supply device provided with a liquid supply unit for supplying fuel to the nozzle, a connection detection sensor for detecting whether or not the nozzle is connected to a fuel supply port to be supplied with fuel; The fuel supply target is captured from the target image acquisition unit that captures the fuel supply target that appears in the liquid area and acquires the captured image information of the fuel supply target, and the captured image information acquired by the target image acquisition unit. A fuel supply target determination unit for determining whether or not the target is a vehicle; an input of a non-storage state detection output from the nozzle detector; an input of a connection detection output from the connection detection sensor to the fuel supply port; and A liquid supply control unit that permits liquid supply driving of the liquid supply unit only while the input of the vehicle determination output from the fuel supply target determination unit is complete.

  According to the fuel supply device according to the present disclosure, the liquid supply control unit inputs the non-contained state detection output from the nozzle detector, the input of the connection detection output to the fuel supply port from the connection detection sensor, and the fuel supply target determination Since the liquid feed drive of the liquid feed section is allowed only while the vehicle judgment output from the section is ready, the customer himself / herself in the self-service filling station ) Even if you try to supply fuel such as gasoline or light oil to the carrying can by operating the oil supply nozzle provided in), the liquid supply equipment (liquid supply part) that supplies oil to the oil supply nozzle is not driven to supply liquid It is possible to ensure the safety of fuel supply work performed by the customer himself.

  In addition, a fuel supply staff member who monitors the customer's own fuel supply work for any abnormalities or errors can operate gasoline or light oil by operating the refueling nozzle provided on the meter (fuel supply device). Even if it is going to refuel the carrying can, etc., the liquid feeding device (liquid feeding part) that supplies the oil to the fuel nozzle is not driven, so there is no abnormality or error in the fuel supply work performed by the customer. It is also possible to reduce the burden on the monitoring staff at the fuel supply station.

  Further, problems, configurations, and effects of the present disclosure other than those described above will be clarified by the following description of embodiments.

It is a schematic structure figure of one example of a measuring machine as one embodiment of a fuel supply device concerning this indication. It is a system block diagram of the weighing machine shown in FIG. It is a flowchart of the liquid supply control process performed by the weighing machine shown in FIG. FIG. 4 is a continuation of the flowchart of the liquid supply control process shown in FIG. 3.

  A fuel supply apparatus according to an embodiment of the present disclosure is applied to a self-service fueling station, and a fuel supply nozzle is inserted into a fuel supply port of a vehicle or the like, and fuel such as gasoline or light oil is supplied to the vehicle or the like An example will be described.

  FIG. 1 is a schematic diagram of an example of a fueling system in a fueling station to which a measuring machine as an embodiment of a fuel supply device according to the present invention is applied. In FIG. 1, only one weighing machine 10 is shown for convenience of explanation, but the number of weighing machines 10 installed at the gas station is arbitrary.

  The self-service type fueling station refueling system shown in FIG. 1 includes a measuring machine 10 in which a customer himself refuels a refueling target vehicle with a refueling nozzle, and a refueling staff member who is also a refueling manager includes a measuring machine 10 and its refueling work. A refueling work management machine 60 that monitors the work status in the area, and a refueling terminal 70 that sets work information related to a refueling work to be performed, such as full / preset, or issues a slip of a finished refueling work, are provided. It has been configured.

  Further, in the illustrated fueling system, the weighing machine 10 is provided with a work situation photographing device 40 for photographing an image of a fueling work area where a vehicle receiving the fueling work stops. The work situation imaging device 40 shoots, for example, a bird's-eye view video of a refueling work area where a refueling target vehicle stops as a monitoring video of a refueling work situation for a refueling target.

  In the illustrated fueling station, the refueling system is such that the weighing machine 10, the refueling work management device 60, and the refueling terminal 70 can transmit and receive data and signals to each other via an SS-LAN (local area network within refueling) 80, respectively. The transmission connection is configured.

  The weighing machine 10 is a ground-mounted weighing machine, and the meter body 10 ′ houses a pump 11 driven by a pump motor 12 and a flow meter 13 for measuring the amount of fuel discharged from the pump 11. ing. An oil supply hose 16 is connected from the weighing machine main body 10 'to the outflow side of the flow meter 13 via an internal pipe 15, and an oil supply nozzle 17 is connected to the tip. The suction side of the pump 11 is connected to the liquid in the underground tank 52 for storing the fuel oil liquid via the underground pipe 51.

  In the weighing machine 10, the fuel oil liquid pumped up from the underground tank 52 by the pump 11 as the liquid feeding device is supplied to the flow meter 13 as the flow measuring device, and the amount of the liquid is measured. A flow rate transmitter 14 is attached to the flow meter 13 to output a flow rate pulse proportional to the flow of the fuel oil liquid for each unit flow rate.

  The oil supply nozzle 17 is stored in a nozzle storage portion 18 provided in the measuring machine main body 2 when not used in an oil supply operation. The refueling nozzle 17 is taken out from the nozzle storage portion 18 during refueling work, and a discharge pipe at the tip is inserted into a refueling port of a vehicle or the like, and a built-in on-off valve is opened by operating an operation lever. Supply is now possible.

  The discharge pipe at the tip of the oil supply nozzle 17 has a nozzle connection detection sensor 20 that detects that the oil supply nozzle 17 is connected to the oil supply port of the oil supply target by inserting the discharge pipe into the oil supply port of the oil supply target. Is provided.

  The nozzle connection detection sensor 20 includes, for example, a light detection sensor that detects whether or not the discharge pipe is inserted into a fuel supply target oil supply port based on a change in brightness between the outside of the fuel supply port and the inside of the fuel supply port, and a supersonic sensor that detects whether the discharge pipe is inserted or not. Based on the presence or absence of reflection of sound waves, there is a force from an ultrasonic detection sensor that detects whether or not the discharge pipe is inserted into the oil supply port to be refueled, or from the inner wall surface of the oil supply port where the discharge pipe abuts the peripheral surface of the discharge pipe. A stress detection sensor or the like is used to detect whether or not the discharge pipe is inserted into the fuel filler port to be lubricated based on whether or not it is acting. Note that the specific configuration of the nozzle connection detection sensor 20 is not limited to these detection sensors as long as the outside / inside of the filler opening can be distinguished and detected.

  In addition, a nozzle switch (nozzle detector) 19 is provided in the nozzle housing portion 18 of the weighing machine main body 10 ′ for detecting removal and withdrawal of the fueling nozzle 17. For example, the nozzle switch 19 is configured by a detection switch that opens / closes in accordance with the removal / retraction of the fuel supply nozzle 17.

  The meter body 10 ′ is provided with a display surface of a fuel indicator 21 that displays fuel information such as the amount of fuel in the current refueling operation, facing the outside from the body surface of the meter body 10 ′. . Furthermore, a state indicator 22 for notifying the operation state of the fueling nozzle 17 is provided on the main body surface of the weighing machine body 10 ′.

  In the measuring machine main body 10 ′, a measuring machine control device 30 for controlling each part of the measuring machine including the work state photographing device 40 is provided in addition to a liquid feeding device such as a pump 11 and a flow meter 13 and a flow measuring device. The weighing machine control device 30 includes a microcomputer device including a memory, an input / output interface, and the like.

  FIG. 2 is a system configuration diagram schematically showing the control system of the weighing machine shown in FIG. Control by each weighing machine control unit 30 will be described with reference to FIG.

  A detection signal from the nozzle connection detection sensor 20, a detection signal from the nozzle switch 19, a monitoring image from the work situation photographing device 40, a flow rate pulse from the flow rate transmitter 14, and the like are input to the weighing machine control device 30. In addition, the weighing machine control device 30 is connected to the SS-LAN 80 via a communication interface (not shown), and between the refueling work management device 60 and the refueling terminal 70 that are also connected to the SS-LAN 80 for transmission. , Mutual information and signals can be transmitted and received.

  In the fueling system of the present embodiment, specifically, the metering device control device 30 uses the metering device 10 to set the fueling terminal 70 previously operated by the customer to operate the fueling terminal 70 before starting the fueling operation. Work information related to the work is supplied. Further, the weighing machine control device 30 receives an overhead view image of the fueling work area photographed by the work situation photographing device 40.

  The weighing machine control device 30 transfers the overhead view video of the refueling work area photographed by the work situation photographing device 40 to the refueling work management device 60 via the SS-LAN 80 as a monitoring video of the refueling work situation.

  In addition, the weighing machine control device 30 analyzes the overhead view image of the refueling work area photographed by the work situation photographing device 40 as the refueling target determination unit 31, and the refueling nozzle 17 is connected during refueling work. It is determined whether the refueling object (refueling object) including the refueling port is a vehicle or a refueling object other than a vehicle including a carrying can.

  In addition, the weighing machine control device 23 receives work information of a refueling operation to be performed which is set by operating the refueling terminal 70 and transmitted from the refueling terminal 70. When the weighing machine control device 23 receives the work information of the refueling operation from the refueling terminal 70 and detects the removal of the refueling nozzle 17 from the nozzle housing portion 18 based on the detection signal from the nozzle switch 19, A work start permission request is transmitted to the refueling work management machine 60.

  When the metering device control device 30 receives a refueling operation start permission for itself as a response from the refueling operation start permission request transmitted to the refueling operation management device 60, Based on the detection signal from the switch 19, the determination output of the lubrication target by the lubrication target determination unit 31, and the detection signal from the nozzle connection detection sensor 20, the liquid feeding device drive unit 25 is controlled to control the pump 11 as the liquid feeding device. Control drive / stop. Then, the operation state of the fuel supply nozzle 17 at that time is notified by controlling the display of the state indicator 22.

  Further, the meter control device 23 serves as a refueling calculation unit 33 from the flow rate transmitter 14 when the refueling nozzle 17 is in a refueling operation state in which the refueling nozzle 17 is taken out from the nozzle storage unit 18 based on the detection signal from the nozzle switch 19. Based on the input of the flow rate pulse, oil supply information such as the oil supply amount in the current oil supply operation is calculated, and the oil supply amount indicator 21 is displayed and controlled.

  Further, when the weighing machine control device 23 detects the return of the fuel supply nozzle 17 to the nozzle storage unit 18 based on the detection signal from the nozzle switch 19, the metering device control device 23 transmits a fuel supply work end report to the fuel supply work management device 60.

  The refueling terminal 70 is usually arranged outdoors in a refueling station, for example, in the vicinity of a refueling work area of the weighing machine 10, and is equipped with input / output devices such as a card information reader, a screen operation setting device, and a slip issuing machine. It is comprised by the computer apparatus which has. The card information reader reads the recorded information from a storage medium such as a customer card, prepaid card, credit card or the like. The screen operation setting device sets and inputs work information related to a refueling work to be performed such as full / preset or sets the contents thereof. The slip issuing machine issues a refueling slip after the refueling operation is completed.

  When the setting of the work information by the customer is completed and the reading of the card information such as the customer card, the prepaid card, and the credit card is completed by the card information reader, the refueling terminal 70 is set via the SS-LAN 80. The work information is transmitted to the weighing machine control device 30 and the refueling work management machine 60 of the weighing machine 10.

  The refueling work management machine 60 is normally disposed in a filling station indoors, for example, in a filling station office, and a refueling staff member who is a refueling manager permits and manages the implementation of self-service refueling work by a customer using the measuring machine 10. . The refueling work management machine 60 is configured by a computer device having an operation screen panel and having a communication function. On the operation screen panel of the refueling work management machine 60, the monitoring video imaged by the work situation photographing device 40 for each refueling work area can be displayed, and the “stop” and “ The operating status such as “waiting”, “waiting for refueling”, “during refueling”, and the operating state of the refueling nozzle 17 in the weighing machine 10 are also displayed in OSD.

  Here, regarding the operating status, “stop” means that the power of the weighing machine 10 is not turned on, and “standby” means that the weighing machine 10 in which the power is turned on is not used for refueling work. The state “Wait for oiling” is a state in which the weighing machine 10 in the operating state is used for refueling work and is waiting for the refueling administrator to confirm the refueling work. The state where the manager has already received permission to confirm the refueling work and is used for the refueling work is shown.

  When the refueling work management machine 60 receives the work information from the refueling terminal 70, the work information is displayed on the operation screen panel in association with the corresponding weighing machine 10 or the refueling work area. Accordingly, the display of the operating status of the corresponding weighing machine 10 changes from “standby” to “waiting for refueling”. When a refueling work permission request is received from the weighing machine 10, confirmation guidance for the corresponding refueling work area pops up on the operation screen panel. In this case, the refueling manager monitors the actual situation of the measuring machine 10 and the refueling work area on which the confirmation guidance is displayed, and monitors the work situation photographing apparatus 40 from the measuring machine control device 30 displayed on the operation screen panel. Check on the video, and if there is no error or abnormality in the work situation so far, permit the refueling work. As a result, the refueling work permission is transmitted via the SS-LAN 80 to the weighing machine 10 that has received a permission request from the refueling work management machine 60. Along with this, in the refueling work management machine 60, the display of the operation status of the corresponding measuring machine 10 changes from “Waiting for fueling” to “Refueling”. Thereafter, when the refueling work management machine 60 receives a refueling work end report from the weighing machine 10 via the SS-LAN 80, work result information such as a refueling amount is displayed on the operation screen panel. Accordingly, the display of the operating status of the corresponding weighing machine 10 changes from “refueling” to “standby”. In this manner, in the refueling work management machine 60, the refueling manager can remotely manage the operation itself and the operation status of the weighing machine 10 on the screen of the operation screen panel.

  In the refueling system configured as described above, the refueling control unit 32 of the weighing machine 10 performs the self-service type refueling work performed by the customer himself / herself operating the refueling nozzle 17 of the weighing machine 10 as shown in FIG. An oil supply control process is performed to control the supply of oil from the oil supply nozzle 17 to the object to be supplied.

FIG. 3 is a flowchart of liquid supply control processing performed by the weighing machine shown in FIG.
FIG. 4 is a continuation of the flowchart of the liquid supply control process shown in FIG.

  When the weighing machine control device 30 receives the work information from the refueling terminal 70, it sets the work information as work information of the self-service refueling work to be performed by the customer (step S010).

  After setting the work information, in the weighing machine control device 30, the oil supply control unit 32 determines whether or not the oil supply nozzle 17 has been taken out from the nozzle storage unit 18 based on the detection signal from the nozzle switch 19 (step S020). Based on the detection signal from the detection sensor 20, whether or not the fueling nozzle 17 is connected to the fueling port to be lubricated (step S021), the fueling target determination unit 31 detects the fueling work area photographed by the work situation photographing device 40. From the current image, it is determined whether or not the refueling nozzle 17 is connected to the refueling port of the refueling target vehicle (step S022).

  Here, the oil supply control unit 32 is based on the detection signal from the nozzle switch 19, although the oil supply nozzle 17 has not been taken out from the nozzle storage unit 18 (NO in step S020), If it is confirmed based on the detection signal that the fuel nozzle 17 is connected to the fuel filler opening (step S021, YES), the status indicator 22 is notified of the abnormality of the nozzle connection detection sensor 20 (step) S023).

  Similarly, based on the detection signal from the nozzle switch 19, the fuel supply control unit 32 determines that the fuel supply nozzle 17 has not been taken out from the nozzle storage unit 18 (NO in step S020) and uses the detection signal from the nozzle connection detection sensor 20 as a detection signal. Based on this, the current image of the refueling work area captured by the work situation photographing device 40 by the refueling target determination unit 31 even though the refueling nozzle 17 is not connected to the refueling target refueling port (step S021, NO). Therefore, if it is confirmed that the refueling nozzle 17 is connected to the refueling port of the refueling target vehicle (step S022, YES), the state indicator 22 causes the refueling target determination unit 31 to recognize a recognition error or work. An imaging error of the situation imaging apparatus 40 is notified (step S024).

  When there is an abnormality in the nozzle connection detection sensor 20, a recognition error by the refueling target determination unit 31, or a photographing error of the work situation photographing apparatus 40, an abnormality report is transmitted to the refueling work management machine 60, and this refueling work The refueling control process according to is temporarily terminated.

  Accordingly, while the refueling control unit 32 repeats the processes of steps S020 to S022, the weighing machine 10 is in a state of waiting for a refueling operation to wait for the customer to take out the refueling nozzle 17 from the nozzle storage unit 18. Then, during this refueling work start waiting state, it is confirmed whether or not the nozzle connection detection sensor 20 and the work situation photographing apparatus 40 have a failure or abnormality.

  When the oil supply control unit 32 confirms that the oil supply nozzle 17 has been removed from the nozzle storage unit 18 based on the detection signal from the nozzle switch 19 (step S020, YES), the oil supply nozzle 17 is displayed on the status indicator 22. Is in a state of being taken out from the nozzle storage unit 18 (step S030). This notification indicates that a refueling operation using the weighing machine 10 is started by the customer and the weighing machine 10 is in a refueling work in progress state. Further, by confirming that the refueling nozzle 17 has been removed from the nozzle storage portion 18, the display on the refueling amount indicator 21 and the like are reset or initialized in preparation for a refueling operation to be performed.

  When it is confirmed that the fuel supply nozzle 17 has been taken out from the nozzle storage portion 18, the fuel supply control unit 32 determines whether the fuel supply nozzle 17 is connected to the fuel supply port to be refueled based on the detection signal from the nozzle connection detection sensor 20. It is confirmed whether or not (step S040). If it is not yet possible to confirm that the fuel supply nozzle 17 is connected to the fuel supply port to be refueled based on the detection signal from the nozzle connection detection sensor 20 (step S040, NO), the fuel supply control unit 32 displays the status indicator 22. To notify the connection guide of the fueling nozzle 17 to the fueling port (step S041), and based on the detection signal from the nozzle switch 19, the fueling nozzle 17 determines whether or not the started fueling operation has been stopped. Confirmation is made based on whether or not the nozzle is housed in the nozzle housing 18 (step S042). Then, if it is not confirmed that the fuel supply nozzle 17 is stored in the nozzle storage unit 18, the fuel supply control unit 32 returns to step S <b> 040, and until the fuel supply nozzle 17 is connected to the fuel supply port by the customer, the steps S <b> 040- Repeat the process of S042.

  Therefore, while the refueling control unit 32 repeats the processes of steps S040 to S042, the weighing machine 10 normally waits for the customer to connect the refueling nozzle 17 to the refueling target refueling port. Applicable.

  At this time, if it is confirmed that the fuel supply nozzle 17 is stored in the nozzle storage unit 18 (step S042, YES), the fuel supply control unit 32 displays the status display as if the current fuel supply operation was stopped halfway. The notification that the refueling nozzle 17 is in the state of being taken out from the nozzle storage portion 18 in the container 22 is terminated (stopped) (step S043), and the refueling control process related to the current refueling operation is terminated.

  On the other hand, if the oil supply control unit 32 has confirmed that the oil supply nozzle 17 is connected to the oil supply port to be supplied based on the detection signal from the nozzle connection detection sensor 20 (step S040, YES), the oil supply is performed. The control unit 32 notifies the state display 22 that the fueling nozzle 17 is connected to the fueling target fueling port (step S050).

  At the same time, the refueling control unit 32 refills the refueling nozzle from the image of the current refueling work area in which the refueling target determination unit 31 is photographed by the work situation photographing device 40 and the refueling nozzle 17 is connected to the refueling target refueling port. It is confirmed whether it is determined that 17 is connected to the fuel filler port of the vehicle to be lubricated, or whether it is determined to be a fuel filler port other than the vehicle including the carrying can (step S060).

  By this confirmation, when the refueling target determination unit 31 determines that the refueling nozzle 17 is connected to the refueling target refueling port other than the vehicle including the carrying can (step S060, NO), the refueling control The unit 32 informs the state indicator 22 that the refueling nozzle 17 is connected to a refueling port other than the vehicle including the carrying can and that the refueling target is not a vehicle but is abnormal. (Step S061). Therefore, it is possible to reliably detect whether or not the refueling operation to be performed is an abnormal refueling operation by determining the refueling target determination after it is detected that the refueling nozzle 17 is connected. Can be alarmed. In this embodiment, the notification that the refueling target is abnormal is sent from the weighing machine control device 30 of the weighing machine 10 to the refueling work management machine 60 as a refueling target abnormality report via the SS-LAN 80. To do. In the refueling work management machine 60 that has received the refueling object abnormality report, a refueling object abnormality regarding the refueling work of the measuring machine 10 is warned. Therefore, the refueling station staff can confirm the occurrence of the abnormality of the refueling object with the refueling work management machine 60 even if the refueling work area of the measuring machine 10 is separated.

  In the illustrated example, the work information itself set by the customer at the refueling terminal 70 can be set on the premise that the refueling work is performed on a refueling target other than the vehicle including the carrying can. High nature. Therefore, in the present embodiment, the fuel supply control unit 32 does not allow the customer to reconnect the fuel supply nozzle 17 to another fuel supply target.

  Therefore, in this embodiment, when it is determined that the fuel filler nozzle 17 is connected to a fuel filler port other than the vehicle including the carrying can (step S060, NO), the customer is first asked. The fueling work based on the work information received from the fueling terminal 70 is stopped.

  Therefore, the refueling control unit 32 confirms that the connection of the refueling nozzle 17 to the refueling port to be refueled is released (step S062) and that the refueling nozzle 17 is hooked back on the nozzle storage unit 18 (step S064). ) When the customer starts the current refueling operation, the refueling operation based on the work information set in step S010 is terminated without actually supplying the oil to the refueling target. ing.

  When the oil supply nozzle 17 is removed by the customer from the oil supply port to be refueled (step S062, NO), the oil supply control unit 32 determines that the oil supply nozzle 17 in the status indicator 22 previously performed in step S050 is the object to be refueled. The notification that the fuel filler port is connected is terminated (step S063). Subsequently, when the removed oil supply nozzle 17 is pulled back to the nozzle storage unit 18 by the customer (YES in step S064), the oil supply control unit 32 in the status indicator 22 previously performed in step S061. The notification that the lubrication target is abnormal is terminated (step S065), and the notification that the lubrication nozzle 17 has been taken out from the nozzle storage unit 18 in the status indicator 22 previously performed in step S030. Is terminated (step S066). As a result, the refueling control unit 32 resets the work information previously set in step S010 (step S210), and the weighing machine 10 is “on standby” in which the refueling nozzle 17 is stored in the nozzle storage unit 18. Return to state.

  On the other hand, from the image of the current refueling work area in which the refueling nozzle 17 is connected to the refueling port of the refueling target, the refueling target determination unit 31 photographed by the work situation photographing device 40 in step S060 described above. When it is determined that the fuel filler nozzle 17 is connected to the fuel filler port of the vehicle to be lubricated (YES in step S060), the fuel filler control unit 32 performs steps when the customer starts the current fueling operation. The refueling work based on the work information set in S010 is executed.

  In this case, the refueling control unit 32 informs the status indicator 22 that the refueling nozzle 17 is connected to the refueling port of the refueling target vehicle (step S070), and informs the start of refueling (step S070). In step S080, the liquid feeding device driving unit 25 is further controlled to start driving the pump 11 as the liquid feeding device (step S090). Thereby, if a customer operates the operation lever of the fuel supply nozzle 17 to open the built-in on-off valve, the supply of the oil liquid from the fuel supply nozzle 17 to the fuel tank of the fuel supply target vehicle via the fuel supply port, that is, Actual refueling (actual refueling) is started.

  When the actual supply is started, in the weighing machine control device 30, the oil supply calculation unit 33 calculates the oil supply information such as the oil supply amount in the current oil supply operation based on the input of the flow rate pulse from the flow rate transmitter 14, The oil supply amount indicator 21 is displayed and controlled (step S100). In addition, when actual supply is started, the fuel supply control unit 32 removes the fuel supply nozzle 17 from the fuel supply port of the fuel supply target vehicle based on the detection signal from the nozzle connection detection sensor 20, and the fuel supply nozzle 17 is connected to the fuel supply target vehicle. It is monitored whether or not the fuel filler is disconnected (step S110). Therefore, after the actual refueling is started in the weighing machine 10, while the customer is refueling the refueling target vehicle from the refueling nozzle 17, the refueling calculation unit 33 continues to calculate and display the refueling information such as the refueling amount. The fuel supply control unit 32 continues to monitor whether or not the fuel supply nozzle 17 is disconnected from the fuel supply port of the fuel supply target vehicle.

  Thereafter, for example, the customer performs a valve closing operation on the oil supply nozzle 17 and the connection between the oil supply nozzle 17 and the fuel supply port of the fuel supply target vehicle is released by the customer. When the refueling calculation unit 33 detects that the connection with the mouth has been disconnected (step S110, NO), the refueling calculation unit 33 performs actual refueling from the refueling nozzle 17 to the refueling port of the refueling target vehicle. Then, the liquid supply device drive unit 25 is controlled as being interrupted, and the drive of the pump 11 as the liquid supply device is stopped (step S120).

  At the same time, the refueling control unit 32 terminates the refueling start notification at the state indicator 22 previously performed at step S080 (step S130), and at the state indicator 22 previously performed at step S050. The notification that the refueling nozzle 17 is connected to the refueling target refueling port is terminated (step S140), and the refueling nozzle 17 connected in step S070 is connected to the refueling target vehicle refueling port. The notification of the existence is terminated (step S150).

  Thus, when the connection between the fuel nozzle 17 and the fuel filler port of the vehicle to be fueled is released by the customer, the fuel control unit 32 takes a picture with the work situation photographing device 40 previously performed in step S060. The determination that the oil supply nozzle 17 is connected to the fuel supply port of the fuel supply target vehicle is reset from the image of the current fuel supply work area in which the fuel supply nozzle 17 is connected to the fuel supply target fuel supply port. . Therefore, the fuel supply control unit 32 returns to the undetermined state of the fuel supply target to which the fuel supply nozzle 17 is connected before the fuel supply nozzle 17 and the fuel supply target are connected.

  Therefore, the refueling control unit 32 again confirms whether or not the refueling nozzle 17 is connected to the refueling target refueling port based on the detection signal from the nozzle connection detection sensor 20 (step S160), and the nozzle switch. Based on the detection signal from 19, the process of confirming whether or not the oil supply nozzle 17 is stored in the nozzle storage portion 18 (step S170) starts to be repeated.

  In this case, while the refueling control unit 32 repeatedly performs the confirmation processing shown in step S160 and the confirmation processing shown in step S170, in the weighing machine 10, for example, the customer is actually refueling the vehicle to be refueled. After closing the refueling nozzle 17 and releasing the connection between the refueling nozzle 17 and the refueling port, the customer ends the current refueling operation or the customer adds to the same fuel tank for the same refueling target. Whether to refuel, whether the customer will continue to refuel another fuel tank of the same refueling, and whether the customer will refuel to another fuel tank of another refueling It corresponds to the waiting state of the customer waiting for work.

  Then, for example, when the customer decides to end the current refueling operation and the refueling nozzle 17 is stored in the nozzle storage unit 18 by the customer, the refueling control unit 32 confirms this by the confirmation processing shown in step S170. (Step S170, YES), the notification that the refueling nozzle 17 is in the state of being taken out from the nozzle storage unit 18 in the status indicator 22 previously performed in Step S030 is ended (stopped) (Step S200). ), Refueling control processing related to the current refueling operation is terminated.

  As a result, the refueling control unit 32 resets the work information previously set in step S010 (step S210), and the weighing machine 10 is “on standby” in which the refueling nozzle 17 is stored in the nozzle storage unit 18. Return to state.

  On the other hand, for example, the customer refuels the same fuel tank of the same refueling vehicle, the customer refuels to another fuel tank of the same refueling vehicle, or the customer refuels another refueling target. When it is determined that the tank is to be refilled, and the customer reconnects the refueling nozzle 17 to the refueling target refueling port, the refueling control unit 32 confirms this by the confirmation process shown in step S160 (step S160). S160, YES).

  Then, when the fuel supply control unit 32 notifies the state indicator 22 that the fuel supply nozzle 17 is connected to the fuel supply port to be supplied with fuel (Step S190), the fuel supply target to which the fuel supply nozzle 17 is connected by the customer is notified. Then, the processing after step S060 described above is performed, and the refueling operation is controlled to be continued or stopped.

  Thereby, when the fuel nozzle 17 is connected again to the fuel filler port to be lubricated by the customer (step S160, YES), in this embodiment, if the lubrication control unit 32 can confirm that the fuel target is a vehicle. Since fuel supply to the refueling target is allowed, additional fuel is supplied to the same fuel tank of the same refueling target vehicle, another fuel tank of the same refueling target vehicle is continued, or multiple refueling target vehicles are continued. It is possible to refuel. However, for example, when fuel is supplied to a fuel tank of a vehicle to be refueled and then an attempt is made to refuel following the loaded carrying cans, the carrying cans cannot be refueled.

  As is clear from the above description, according to the fueling device of the present embodiment, the customer himself / herself operates the fueling nozzle provided in the measuring machine and carries gasoline or light oil at the self-service type fueling station. Even if an attempt is made to supply oil to the can, the liquid supply device for supplying the oil liquid to the oil supply nozzle is not driven to supply liquid, so that the safety of the oil supply work performed by the customer himself can be ensured.

  In addition, gas station staff who monitor customers for any abnormalities or mistakes in refueling work themselves operate the refueling nozzles provided on the weighing machines to refuel gasoline and light oil into carry-on cans. However, since the liquid feeding device that supplies the oil to the fuel nozzle is not driven, it is possible to reduce the burden on the staff of the gas station that monitors whether there is any abnormality or error in the oiling work performed by the customer himself / herself.

  The fuel supply device according to the present invention is not limited to the weighing machine of the above-described embodiment, and various modifications can be made.

  For example, in the weighing machine 10 of the above-described embodiment, when gasoline or light oil is to be supplied to the carrying can, the pump 11 (pump motor 12) is not driven. It is also possible to provide a solenoid valve that does not open when gasoline or light oil is supplied to the carrying can.

  Further, in the weighing machine 10 of the above-described embodiment, whether the refueling target to which the refueling nozzle 17 is connected is a vehicle or a vehicle other than the vehicle based on the image of the refueling area photographed by the work situation photographing device 40. Although it comprised so that it might determine with the lubrication object determination part 31, the determination method is not limited to this.

  Further, in the weighing machine 10 of the above-described embodiment, the work situation photographing device 40 is configured separately from the weighing machine body 10 ′, but may be provided integrally with the weighing machine 10 ′, and further, a fueling nozzle. 17 can also be configured to serve as the nozzle connection detection sensor 20.

  In the weighing machine 10 according to the above-described embodiment, when gasoline or light oil is to be supplied to the carrying can, the fuel supply operation is stopped and reset. However, the fuel supply nozzle 17 is hooked back to the nozzle housing portion 18. If it is confirmed that the staff at the filling station will perform the refueling work on behalf of the customer on the weighing machine 10 side, the refueling work for the suspended cans of gasoline and light oil can be continued. It is also possible to do. In this case, confirmation that the filling station staff member performs the refueling operation on the weighing machine 10 side may be performed by, for example, providing a separate authorization request from the refueling work management machine 60 provided with an authentication device for the filling station staff member on the weighing machine 10 side. Various methods such as receiving can be used.
