By the way, at the gas station, when the setting related to refueling by the refueling person is completed (that is, when the state of waiting for refueling permission is reached), the staff member confirms the image (image) around the measuring machine displayed on the monitor of the management device. Or, after visually checking the vicinity of the measuring machine, the management device sends a refueling permission signal to the measuring machine by operating the button of the management device. Here, after the staff member sends the refueling permission signal, for example, the refueling person mistakenly operates the lever of the refueling nozzle while the discharge pipe of the refueling nozzle is not deeply inserted into the fuel filling port (fueling port) of the fuel tank. If this happens, a large amount of fuel may be discharged from the refueling nozzle.

An object of an embodiment of the present invention is to provide a gas station management system capable of suppressing a large amount of fuel from being discharged from a refueling nozzle due to an erroneous operation of a refueling person or the like.

One embodiment of the present invention is a detection that detects a situation in a gas station in a gas station management system including a measuring machine that supplies fuel to a vehicle and a management machine that manages the fuel supply by the measuring machine. The fuel supply speed or flow rate of the measuring machine is changed according to the means, the abnormality determining means for determining the presence or absence of an abnormality in the gas station from the situation detected by the detecting means, and the determination result by the abnormality determining means. It is equipped with control means.

According to one embodiment of the present invention, it is possible to prevent a large amount of fuel from being discharged from the refueling nozzle due to an erroneous operation of the refueling person or the like.

It is an overall block diagram which shows typically the gas station management system by embodiment. It is a flow chart which shows the control process performed by the management apparatus (management machine) in FIG. It is a flow chart which shows the process which follows FIG.

Hereinafter, a case where the refueling station management system according to the embodiment is applied to a refueling station (gas station, service station) that refuels a vehicle such as an automobile will be described as an example, and will be described with reference to the attached drawings. Each step of the flow chart shown in FIGS. 2 and 3 uses the notation "S" (for example, step 1 = "S1").

In FIG. 1, the gas station 1 is configured as a self-service gas station in which the driver of a vehicle (not shown) can refuel as a gas station. The gas station 1 serving as a fuel supply station is provided with a measuring machine 2 that supplies fuel (fueling) to the vehicle. At the gas station 1, refueling work (supply work) of refueling (replenishing) the vehicle with fuel such as regular gasoline, high-octane gasoline, and light oil is performed using the measuring machine 2. The measuring machine 2 which is a fuel supply device (fuel supply machine, refueling machine) is installed in a refueling lane (refueling booth) of a gas station 1. Note that FIG. 1 shows one of a plurality of measuring machines 2 installed in the gas station 1 in order to avoid complicating the drawings.

The ground-mounted weighing machine 2 has a housing 3 having a substantially square shape. A monitor device 18, a setting device 19, and the like are provided on the front side of the housing 3. The measuring machine 2 includes a liquid supply line 6, a supply pump 13 (hereinafter referred to as a refueling pump 13), a flow meter 14, a supply hose 8 (hereinafter referred to as a refueling hose 8), and a supply nozzle 9 (hereinafter referred to as a refueling nozzle 9). ) Is provided. A liquid feed pipe line 6, a refueling pump 13, a flow meter 14, a pump motor 15, a control valve 17, a control device 20, and the like are provided in the housing 3 of the measuring machine 2.

On the other hand, in the basement of the gas station, for example, a storage tank 4 (hereinafter referred to as an underground tank 4) for storing fuels such as regular gasoline, high-octane gasoline, and light oil is buried. The underground tank 4 is provided separately or divided into a plurality of tanks, and fuels having different liquid types (for example, regular gasoline, high-octane gasoline, and light oil) are stored in each tank. The liquid level 5 in the underground tank 4 is detected using, for example, a dedicated liquid level detector (not shown), whereby the remaining amount of liquid in the underground tank 4 is monitored.

Note that FIG. 1 simplifies the internal structure of the measuring machine 2 (that is, the piping structure of the liquid feeding pipe line 6, the refueling pump 13, the flow meter 14, the control valve 17, and the like). Actually, a plurality of refueling hoses 8 are provided for each liquid type on the left and right sides or the front side of the housing 3, but in FIG. 1, one refueling hose 8 is shown, and the other refueling hoses are described. It is omitted for the sake of simplicity. The same applies to the underground tank 4.

The liquid supply pipe line 6 is connected between the underground tank 4 and the refueling hose 8. That is, one end (lower end) side of the liquid feed pipe line 6 extends downward from the inside of the housing 3. One end side of the liquid feed pipe line 6 becomes a suction pipe 6A and is connected to the underground tank 4. On the other hand, the other end (tip) side of the liquid feed pipe line 6 is connected to the flexible oil supply hose 8 via, for example, a joint 7. The liquid supply line 6 together with the refueling hose 8 constitutes a fuel supply path.

A refueling nozzle 9 for supplying liquid fuel to a fuel supply body (not shown) such as a fuel tank of a vehicle is provided on the tip end side of the refueling hose 8. The refueling nozzle 9 is hooked on the nozzle hook 11 while waiting for the refueling work. For example, a refueling person (including a self-refueling person) who refuels removes the refueling nozzle 9 from the nozzle hook 11, and in this state, refuels the fuel tank of the vehicle.

Here, the vehicle is provided with a fuel filler port (lubricating port, supply port) for refueling (replenishing) fuel in the fuel tank. The refueling nozzle 9 is provided with a discharge pipe 9A as a nozzle tip. The discharge pipe 9A is refueled to the fuel tank in a state of being inserted into the refueling port. Further, the refueling nozzle 9 has a nozzle lever that is manually operated. A valve (not shown) is provided in the refueling nozzle 9, and the opening degree of this valve is adjusted by the operating position of the nozzle lever.

The housing 3 of the weighing machine 2 is provided with a nozzle hook 11 as a nozzle accommodating portion. A refueling nozzle 9 is detachably hooked to the nozzle hook 11. That is, the refueling nozzle 9 is usually housed in the nozzle hook 11. When the vehicle arrives at the gas station 1, the refueling nozzle 9 is removed from the nozzle hook 11 by the refueling person and inserted into the refueling port of the fuel tank of the vehicle. Further, a nozzle switch 12 is attached to the nozzle hook 11. The nozzle switch 12 is connected to the control device 20.

The nozzle switch 12 detects whether or not the refueling nozzle 9 is hooked on the nozzle hook 11, and outputs the detection signal to the control device 20. While the refueling nozzle 9 is hooked on the nozzle hook 11, for example, an ON signal is output from the nozzle switch 12 to the control device 20. While the refueling nozzle 9 is removed from the nozzle hook 11, an OFF signal is output from the nozzle switch 12 to the control device 20.

A refueling pump 13, a flow meter 14, and a control valve 17 are arranged in the housing 3 in the middle of the liquid feed pipe line 6. The flow rate of the liquid fuel (for example, regular gasoline) in the underground tank 4 sucked up from the suction pipe 6A by the refueling pump 13 is measured by the flow meter 14 when flowing in the liquid supply pipe line 6. The refueling pump 13 is rotationally driven by the pump motor 15 in order to supply the fuel in the underground tank 4 to the refueling nozzle 9 side. In this case, the rotation of the pump motor 15 is transmitted to the rotating shaft of the refueling pump 13 via the belt 16 wound between the drive pulley 15A of the pump motor 15 and the driven pulley 13A of the refueling pump 13.

The flow meter 14 is a flow rate detecting device that individually measures the amount of liquid fuel supplied to the refueling nozzle 9 by the refueling pump 13 for each refueling nozzle 9. For example, the flow meter 14 is provided with a flow pulse transmitter 14A. The flow rate pulse transmitter 14A is connected to the control device 20. The flow rate pulse transmitter 14A outputs a flow rate pulse signal corresponding to the flow rate of the liquid fuel flowing in the liquid feed line 6 to the control device 20.

The control valve 17 is composed of an electromagnetic flow rate control valve whose valve opening degree is variably controlled. The control valve 17 adjusts the flow rate of the liquid fuel supplied from the liquid feed pipe line 6 to the refueling nozzle 9 via the refueling hose 8. The control valve 17 is connected to the control device 20. The valve opening degree of the control valve 17 is variably controlled, for example, by variably controlling the drive current supplied to the control valve 17 according to the frequency and duty ratio of the control signal output from the control device 20. .. Regarding the opening and closing of the control valve 17, the flow rate of the liquid is continuously controlled by ON / OFF control (fully open / fully closed control of the valve opening) using pulse width modulation. May be good.

On the front side of the housing 3, there is a monitor device 18 as a display means (display means on the measuring machine side) for displaying the fuel refueling amount, amount, etc. by the measuring machine 2, and the refueling amount, etc. by manual operation by the refueling person. A setting device 19 is provided as a setting means for making settings related to the above. The monitor device 18 includes, for example, a liquid crystal monitor and a speaker (acoustic output device). The liquid crystal monitor (display screen) of the monitor device 18 displays the amount of refueling and the like. Further, voice information, a warning sound, and the like are output from the speaker of the monitor device 18 as needed. The monitoring device 18 constitutes a notification means (refueler side notification means) for notifying (displaying and outputting voice) information necessary for the refueling person.

Further, on the display screen of the monitor device 18, for example, a setting item selected by the setting device 19 is displayed. By operating each switch of the setting device 19, the refueling person can perform an operation of selecting a full tank refueling, an operation of setting an arbitrary preset refueling amount, and the like. Note that FIG. 1 shows a case where the monitor device 18 and the setting device 19 are separately provided. For example, by configuring the monitor device 18 with a touch panel, the monitor device 18 and the setting device 19 can be provided. It may be configured integrally.

In the housing 3 of the measuring machine 2, a control device 20 is provided as a control means for controlling refueling based on the refueling amount set by the setting device 19. The control device 20 causes the monitor device 18 to display the amount of refueling measured by the flow meter 14 when the fuel is refueled by the refueling nozzle 9. As shown in FIG. 1, the input side of the control device 20 is connected to the nozzle switch 12 of the nozzle hook 11, the flow pulse transmitter 14A of the flow meter 14, the setting device 19, and the like. The output side of the control device 20 is connected to a pump motor 15, a control valve 17, a monitor device 18, etc. that drives the refueling pump 13. The control device 20 is also connected to the management device 23, which will be described later.

The control device 20 starts the pump motor 15 when the refueling nozzle 9 is removed from the nozzle hook 11 and an OFF signal from the nozzle switch 12 is input. As a result, the refueling pump 13 sucks the fuel in the underground tank 4 from the liquid feed pipe line 6. Further, the control device 20 controls the control valve 17 by outputting a drive signal having a predetermined frequency to the control valve 17. In this case, the control device 20 controls the control valve 17 so as to maintain a predetermined valve opening degree by changing the duty ratio of the drive signal.

When the nozzle lever of the refueling nozzle 9 is operated in this state, refueling to the fuel tank of the vehicle is started. At this time, the flow rate pulse is output to the control device 20 from the flow rate pulse transmitter 14A of the flow meter 14. The control device 20 integrates the flow rate pulses output from the flow rate pulse transmitter 14A and displays the refueling amount on the display screen of the monitor device 18. Further, the control device 20 stops refueling when the tank is full or when the refueling amount set by the setting device 19 is reached, for example, such as full tank refueling control or preset refueling control.

The control device 20 controls various devices such as the pump motor 15, the control valve 17, and the monitor device 18 of the measuring machine 2. For this purpose, the control device 20 includes, for example, a microprocessor, a power supply circuit, a drive circuit, and the like. The microcomputer of the control device 20 has a memory including a ROM, a RAM, and / or a non-volatile memory, in addition to an arithmetic processing unit called a CPU.

The memory stores (stores) a processing program for controlling refueling such as full tank refueling control or preset refueling control. Further, in the memory of the control device 20, a processing program or the like for displaying and / or outputting voice of the monitoring device 18 based on a command (notification command) from the management device 23 described later is also stored.

The static electricity removing sheet 21, which is a static electricity removing unit, is provided, for example, on the front surface of the housing 3 of the measuring machine 2. The static electricity removing sheet 21 is formed in a circular shape using, for example, a conductive material, and is grounded. The refueling person touches the static electricity removing sheet 21 by hand before refueling. When the refueling person touches the static electricity removing sheet 21, the static electricity charged on the refueling person is removed.

The emergency stop notification lamp 24 (hereinafter referred to as an alarm lamp 24), which is an emergency stop notification means, is provided, for example, on the front surface of the housing 3 of the measuring machine 2. The alarm lamp 24 lights up when the refueling by the measuring machine 2 is stopped by operating the emergency stop button (not shown) or the like to notify the refueling person or the like that the refueling by the measuring machine 2 is stopped. .. The alarm lamp 24 is connected to, for example, the control device 20, and is turned on by the output from the control device 20.

A surveillance camera 22 as a means of photographing is installed in the gas station 1. The surveillance camera 22 photographs the vicinity of the weighing machine 2 in order to monitor the state of the refueling lane, the entry / exit of the vehicle, the refueling operation of the refueling person, and the like. The surveillance camera 22 constitutes a detection means for detecting the situation in the gas station 1. The surveillance camera 22 is arranged so that, for example, a refueling lane, a vehicle, a measuring machine 2, a refueling person who refuels, and the like are included in an image (shooting range). In this case, although not shown, the images may be acquired separately by installing a plurality of surveillance cameras 22. The surveillance camera 22 is connected to the management device 23 wirelessly or by wire. The image taken by the surveillance camera 22 is transmitted to the management device 23.

The management device 23 as a management machine is a refueling management device that manages the fuel supply (refueling) by the measuring machine 2. The management device 23 is provided, for example, in a management building (not shown) on the premises of the gas station 1. The management device 23 is connected to the control device 20 of the weighing machine 2. The management device 23 receives the state of the weighing machine 2 from the control device 20 of the measuring machine 2. Further, the management device 23 is connected to the surveillance camera 22. The management device 23 receives an image (shooting result) from the surveillance camera 22. The management device 23 transmits a refueling permission signal to the control device 20 of the measuring machine 2. When the control device 20 of the measuring machine 2 receives the signal of the refueling permission from the management device 23, the control device 20 can refuel the vehicle through the refueling nozzle 9.

The management device 23 is composed of, for example, a desktop computer, and includes a monitor 23A. The monitor 23A corresponds to a display means (display means on the management machine side) for displaying information related to refueling. The monitor 23A can be configured by, for example, a touch panel (liquid crystal touch panel) capable of input operation, selection operation, and the like. The monitor 23A displays an image (image) of the surveillance camera 22, that is, a live image (live image) of a refueling lane, a vehicle, a measuring machine 2, a refueling person, and the like.

Further, the monitor 23A displays the refueling status of each refueling lane and each measuring machine 2. For example, on the monitor 23A, the oil type, the amount of refueling, etc. set by the refueling person are displayed for each measuring machine 2 in each refueling lane, and the judgment information, the judgment result, the judgment image, etc. by the abnormality determination means described later are displayed. Judgment items and operation buttons (menu button, confirmation button, stop button, release button, permission button, emergency stop button, etc.) are displayed. Further, the management device 23 includes a storage device such as a hard disk. A processing program for managing the weighing machine 2 is stored (stored) in the storage device of the management device 23. Further, the storage device of the management device 23 also stores (stores) a processing program for executing the processing flow shown in FIGS. 2 and 3 described later.

In the illustrated example, the management device 23 is connected to one measuring machine 2 in the gas station 1, but a plurality of measuring machines 2 (for example, refueling) in the gas station 1 including another measuring machine (not shown). It is connected to all the weighing machines 2) in the place 1. Further, the management device 23 is a management server that transmits and receives information (data) signals and signals corresponding to commands to and from "a management device of another refueling station (not shown)" and / or "a plurality of management devices 23". (For example, main server, data server, cloud server, etc.) ”. The management device 23 and / or the management server corresponds to a management machine that manages refueling by the measuring machine 2.

By the way, at the gas station 1, a staff member (refueling manager) monitors the refueling operation of the refueling person (self-refueling person) visually or by the image of the monitoring camera 22. For example, when the refueling setting by the refueling person is completed (waiting for refueling permission), the staff member confirms the image (image) around the measuring machine 2 displayed on the monitor 23A of the management device 23, or After visually confirming the vicinity of the measuring machine 2, the management device 23 transmits a refueling permission signal to the measuring machine 2 by operating the button (switch) of the management device 23.

Here, for example, consider a case where a staff member goes to the site to perform further confirmation or the like after the staff member has transmitted a refueling permission signal, that is, in a state where refueling by the measuring machine 2 is possible. In such a case, if the fuel discharge flow rate from the refueling nozzle 9 is large, if the refueling person accidentally operates the refueling nozzle 9 on the way to the site, the refueling nozzle 9 will be used. There is a possibility that a large amount of fuel will be discharged. That is, after the staff member transmits the refueling permission signal, for example, the refueling person mistakenly inserts the refueling nozzle 9 into the refueling port (lubricating port) of the fuel tank of the vehicle without the discharge pipe 9A of the refueling nozzle 9 being inserted deeply. If the lever is operated, a large amount of fuel may be discharged from the refueling nozzle 9.

On the other hand, in recent years, due to the shortage of personnel, there is a tendency that a small number of staff members must monitor the refueling person's abnormal behavior in addition to the refueling person's refueling monitoring. In addition, for example, depending on the gas station, the number of self-service gas stations with retail stores such as convenience stores and coffee shops is increasing, and the tasks (work volume) of staff members tend to increase. On the other hand, in order to reduce the burden on the staff, for example, it is conceivable to support the safety confirmation performed by the staff by the image recognition technology by machine learning of AI (artificial intelligence).

Specifically, whether or not there is an abnormality (unfavorable situation, operation) in the situation of the gas station 1 and / or the operation of the refueling person by using the abnormality determination means (abnormality analysis means) using the image recognition technology by AI. It is conceivable to judge (analyze) whether or not. However, for example, if the weighing machine 2 is simply stopped automatically based on the AI determination result (analysis result), the measuring machine 2 is stopped unnecessarily and it takes time to complete the refueling. The efficiency of refueling work may decrease.

Therefore, the gas station management system of the embodiment determines the presence or absence of an abnormality in the gas station 1 from the image (video) taken by the surveillance camera 22. This determination (abnormality determination) is performed by a management server (hereinafter, simply referred to as "management device 23") connected to the management device 23 and / or the management device 23 via a network. From the image (video) of the monitoring camera 22, for example, whether the refueling person touches the static electricity removing sheet 21 and whether the discharge pipe 9A of the refueling nozzle 9 is inserted into the refueling port of the fuel tank of the vehicle. Whether or not there is the use of fire such as cigarettes or lighters, whether or not the vehicle suddenly started during refueling, whether or not the engine of the vehicle is stopped, and whether or not the refueling person is changed during refueling. Whether or not there is a person other than the refueling person during refueling, whether or not the discharge pipe 9A of the refueling nozzle 9 is shallowly inserted into the refueling port of the fuel tank during refueling, and whether or not refueling is performed during refueling. It is determined whether or not the person is making extra observations, whether or not the refueling person is using a mobile phone, and the like.

Here, for example, "the refueling person is not touching the static electricity removing sheet 21", "the discharge pipe 9A of the refueling nozzle 9 is not inserted into the refueling port of the fuel tank of the vehicle, or is inserted shallowly", "Fire such as cigarettes and lighters is used", "The vehicle suddenly started during refueling", "The engine of the vehicle is not stopped (the engine was started)", "Refueling during refueling" Refueling station 1 The situation is not preferable as the behavior of the refueling person. Therefore, the management device 23 (abnormality determination means) determines that there is an abnormality when there is such an unfavorable situation of the gas station 1 or the operation of the refueling person. Such a determination can be made by using, for example, an image recognition technique based on AI (artificial intelligence). The determination of abnormality by AI is, for example, "an image (video) of an appropriate operation (favorable operation) and an inappropriate operation (unfavorable operation) of a refueling person", "an appropriate situation (favorable situation) of a refueling station 1", and "an appropriate situation (favorable situation) of a refueling station 1". An image (video) of an inappropriate situation (unfavorable situation) ”or the like can be machine-learned in advance by AI, and this can be performed based on the learning result and the image (video) of the surveillance camera 22.

When the management device 23 determines that there is an abnormality in the operation related to the refueling of the refueling person or the condition of the gas station 1, the refueling pump 13 (pump motor 15) of the measuring machine 2, the control valve 17, etc. are set based on the determination result. Control. That is, the management device 23 changes the fuel supply amount by the measuring machine 2, specifically, the fuel supply speed or the flow rate, based on the determination result. Specifically, when the management device 23 determines from the image (video) of the surveillance camera 22 that "a fire such as a cigarette or a lighter is used" based on the image recognition technology of AI, the weighing machine is used. The refueling pump 13 (pump motor 15) of 2 is stopped (emergency stop). In this case, the management device 23 lights the alarm lamp 24 and notifies the refueling person that the emergency stop has occurred via the monitoring device 18 of the measuring machine 2.

For example, "emergency stop" is displayed on the display screen of the monitor device 18, and an alarm sound (buzzer sound) or a voice indicating that the emergency stop is output is output from the speaker of the monitor device 18. For this purpose, the management device 23 outputs a fuel supply stop command and an emergency stop notification command to the control device 20 of the measuring machine 2. The control device 20 of the measuring machine 2 stops the refueling pump 13 and closes the control valve 17 and lights the alarm lamp 24 based on the fuel supply stop command and the emergency stop notification command from the control device 23. , Screen display of the monitor device 18, audio output, and the like. Further, in the case of an emergency stop, the management device 23 notifies the staff that the emergency stop has occurred. For example, "emergency stop" is displayed on the monitor 23A of the management device 23, and a buzzer sound or a voice indicating that the emergency stop is output is output from the speaker of the management device 23.

Further, the management device 23 states that, for example, "the discharge pipe 9A of the refueling nozzle 9 is shallowly inserted into the refueling port of the fuel tank of the vehicle" based on the image recognition technology of AI from the image (video) of the surveillance camera 22. If it is determined, the fuel supply speed or flow rate by the weighing machine 2 is reduced. For example, when the fuel supply speed or flow rate when it is determined by the management device 23 that there is no abnormality is set to a preset value, the management device 23 presets the fuel supply speed or flow rate by the measuring machine 2. Lower than the value given. Further, the management device 23 provides a notification for encouraging the refueling person to take a favorable action via the monitoring device 18 of the measuring machine 2. For example, "Please insert the discharge pipe 9A deeply into the fuel tank filler port of the vehicle" is displayed on the display screen of the monitor device 18, and the speaker of the monitor device 18 outputs a voice to that effect.

For this purpose, the management device 23 outputs a fuel supply reduction command and a notification command to the control device 20 of the measuring machine 2. The control device 20 of the measuring machine 2 controls the refueling pump 13 (pump motor 15) and / or the control valve 17 based on the fuel supply decrease command from the control device 23 to control the fuel supply speed or flow rate in advance. Lower than the set value. Further, the control device 20 of the weighing machine 2 displays the screen and outputs the voice of the monitor device 18 based on the notification command from the management device 23.

Further, even when the management device 23 determines that "it cannot be determined from the image of the surveillance camera 22 whether it is normal or abnormal and is unknown", the fuel supply speed or flow rate by the measuring machine 2 is set in advance. Lower than the value given. In this case, the management device 23 outputs a fuel supply reduction command to the control device 20 of the measuring machine 2. The control device 20 of the measuring machine 2 controls the refueling pump 13 (pump motor 15) and / or the control valve 17 based on the fuel supply decrease command from the control device 23 to control the fuel supply speed or flow rate in advance. Lower than the set value.

Further, when the management device 23 determines, for example, "the refueling person is using a mobile phone" based on the image recognition technology of AI from the image (video) of the surveillance camera 22, the fuel by the measuring machine 2 is used. Maintain supply speed or flow rate. In this case, the management device 23 notifies the refueling person of a favorable action via the monitoring device 18 of the measuring machine 2. For example, "Please refrain from using a mobile phone" is displayed on the display screen of the monitor device 18, and the speaker of the monitor device 18 outputs a voice to that effect. For this purpose, the management device 23 outputs a necessary notification command to the control device 20 of the measuring machine 2. The control device 20 of the weighing machine 2 performs screen display and voice output of the monitoring device 18 as necessary based on the notification command from the management device 23.

Here, the management device 23 divides the degree of abnormality into three stages of "high", "medium", and "low". In this case, the high-risk abnormality is defined as "high" abnormality, the medium-risk abnormality is defined as "medium" abnormality, and the low-risk abnormality is defined as "low" abnormality. For example, if "there is the use of fire such as cigarettes or lighters", "the vehicle suddenly started during refueling", or "the vehicle's engine has not stopped (the engine has started)", refueling is stopped immediately. It is considered as a "high" abnormality that needs to be (emergency stop). For example, "the refueling person is being replaced during refueling", "there is a person other than the refueling person during refueling", and "the discharge pipe 9A of the refueling nozzle 9 is shallow at the refueling port of the fuel tank of the vehicle". If it is "inserted", it is considered to be a "medium" abnormality that does not need to stop refueling at this time but is likely to develop into a dangerous state. If "the refueler is making extra observations during refueling" or "the refueler is using a mobile phone", it is unlikely that the situation will develop into a dangerous state, and it is a "low" abnormality that calls attention. There is.

The management device 23 controls the fuel supply speed or flow rate by the measuring machine 2 according to the degree of abnormality. For example, when the management device 23 determines that the degree of abnormality is "high", it stops the refueling pump 13 of the measuring machine 2 (emergency stop) and gives necessary notification. When the control device 23 determines that the degree of abnormality is "medium", the control device 23 reduces the fuel supply speed or flow rate by the measuring machine 2 and performs necessary notification. When the control device 23 determines that the degree of abnormality is "low", the management device 23 performs necessary notification without reducing the fuel supply speed or flow rate by the measuring machine 2.

Further, after the management device 23 reduces the fuel supply speed or flow rate by the measuring machine 2 based on the abnormality determination result, if it is determined that there is no abnormality, the fuel supply speed or flow rate by the measuring machine 2 is determined in advance. Restores to the set value. That is, the management device 23 constantly determines the abnormality from the image (video) of the surveillance camera 22. When the management device 23 determines, for example, that "the discharge pipe 9A of the refueling nozzle 9 is shallowly inserted into the refueling port of the fuel tank of the vehicle" based on the image (video) of the surveillance camera 22, the fuel supply speed is determined. Alternatively, the flow rate is reduced, and the refueler is notified via the monitor device 18 to encourage proper action.

Based on this notification, when the refueling person deeply inserts the discharge pipe 9A, the management device 23 determines from the image (video) of the surveillance camera 22 that there is no abnormality. The management device 23 returns the fuel supply speed or flow rate by the measuring machine 2 to a preset value based on the determination that there is no abnormality. In this case, the management device 23 outputs a fuel supply return command to the control device 20 of the measuring machine 2. The fuel supply return command may be configured to be output by the operation of a staff member. That is, the staff member determines that the discharge pipe 9A has been deeply inserted, and the staff member operates the management device 23 based on this determination, so that the management device 23 issues a fuel supply return command to the control device 20 of the measuring machine 2. It may be output.

2 and 3 are flow charts (flow charts) showing control processes performed by the management device 23. The control process performed by the management device 23 will be described with reference to FIGS. 2 and 3. It should be noted that the surveillance camera 22 constantly photographs the inside of the gas station 1.

The control process shown in FIGS. 2 and 3 is started, for example, when the vehicle enters the refueling lane. In S1, it is determined whether or not the refueling setting by the refueling person is completed. That is, in S1, whether or not the refueler has completed the settings before the start of refueling, such as selection of payment method, selection of oil type, selection of full tank refueling, selection of arbitrary preset refueling amount, etc. using the setting device 19. Is determined. If it is determined in S1 that "NO", that is, the setting of refueling by the refueler has not been completed, the process of S1 is repeated. On the other hand, if it is determined in S1 that "YES", that is, the setting of refueling by the refueling person is completed, the process proceeds to S2.

In S2, "whether or not the refueling person touches the static electricity removing sheet 21" is determined from the image of the surveillance camera 22. The determination from the image (video) can be performed by using the image recognition technique by AI (artificial intelligence). The same applies to the determination of S7, S10, and S23 described later. If it is determined in S2 that "NO", that is, the refueling person is not touching the static electricity removing sheet 21, the process of S2 is repeated. In this case, the management device 23 outputs a command signal to the control device 20 of the weighing machine 2, and outputs a voice saying "Please touch the static electricity removal sheet" from the speaker of the monitoring device 18 to the refueling person. You may give a notification to urge you to touch the static electricity removal sheet 21.

On the other hand, if "YES" in S2, that is, it is determined that the refueling person has touched the static electricity removing sheet 21, the process proceeds to S3. At this time, the management device 23 displays the determination result and the determination image to the effect that the refueling person touches the static electricity removal sheet 21 on the monitor 23A. In S3, it is determined whether or not the refueling nozzle 9 has been removed from the nozzle hook 11. This determination can be made based on whether the nozzle switch 12 is ON or OFF. If it is determined in S3 that "NO", that is, the refueling nozzle 9 has not been removed from the nozzle hook 11 (nozzle switch 12 is ON), the process of S3 is repeated. On the other hand, if it is determined in S3 that "YES", that is, the refueling nozzle 9 has been removed from the nozzle hook 11 (nozzle switch 12 is OFF), the process proceeds to S4.

In S4, the staff is notified that the refueling nozzle 9 has been removed from the nozzle hook 11. That is, the management device 23 includes, for example, a buzzer as a notification means (management device side notification means). By sounding the buzzer, the management device 23 urges the staff to select the lane (weighing machine 2) to be refueled. That is, the management device 23 sounds a buzzer in order to have the staff confirm the lane (weighing machine 2) to be refueled. After sounding the buzzer in S4, proceed to S5. In S5, it is determined whether or not the staff member has selected the lane (weighing machine 2) from which the refueling nozzle 9 has been removed. That is, in S5, the staff operates the management device 23 to determine whether or not the lane (weighing machine 2) to be refueled is selected.

If it is determined in S5 that "NO", that is, the person in charge has not selected the lane (weighing machine 2), the process of S5 is repeated. On the other hand, if "YES" in S5, that is, it is determined that the staff member has selected the lane (weighing machine 2), the process proceeds to S6. In S6, the notification to the staff is stopped. That is, the management device 23 stops the buzzer. In the following S7, it is determined from the image of the surveillance camera 22 "whether or not the discharge pipe 9A of the refueling nozzle 9 is inserted into the refueling port of the fuel tank of the vehicle". If it is determined in S7 that "NO", that is, the discharge pipe 9A of the refueling nozzle 9 is not inserted into the refueling port of the vehicle, the process of S7 is repeated. In this case, the management device 23 outputs a command signal to the control device 20 of the measuring machine 2, and "insert the discharge pipe 9A of the refueling nozzle 9 to the back of the refueling port of the vehicle" from the speaker of the monitor device 18. The refueling person may be notified to insert the refueling nozzle 9, such as by outputting the voice of.

On the other hand, if "YES" in S7, that is, it is determined that the discharge pipe 9A of the refueling nozzle 9 has been inserted into the refueling port of the vehicle, the process proceeds to S8. At this time, the management device 23 displays a determination result and a determination image indicating that the discharge pipe 9A of the lubrication nozzle 9 has been inserted into the fuel filler port of the vehicle on the monitor 23A. In S8, it is determined whether or not the staff has given permission to refuel. That is, the staff member visually confirms the live image (live image) of the surveillance camera 22 displayed on the monitor 23A of the management device 23, the determination results of S2 and S7 based on the image of the surveillance camera 22, and the vicinity of the weighing machine 2. Based on the above, it is determined whether or not the refueling by the refueling person is permitted. When permitting refueling, the staff operates the management device 23 to transmit a refueling permission signal from the management device 23 to the measuring machine 2. In S8, it is determined whether or not refueling is permitted by the operation of the management device 23 of the staff. If it is determined in S8 that "NO", that is, refueling is not permitted (the refueling permission signal is not output), the process of S8 is repeated. On the other hand, if it is determined in S9 that "YES", that is, refueling is permitted (a refueling permission signal is output), the process proceeds to S9. In S9, the refueling pump 13 of the measuring machine 2 is driven based on the permission signal from the management device 23. In this case, the refueling pump 13 can be driven with, for example, the maximum discharge amount.

When the refueling pump 13 is driven in S9, the process proceeds to S10 via "A" in FIG. 2 and "A" in FIG. In S10, "abnormality during refueling" is determined from the image of the surveillance camera 22. That is, the management device 23 constantly determines whether or not there is an abnormality in the gas station 1 from the image (video) of the surveillance camera 22 by using the image recognition technique by AI (artificial intelligence) during refueling. In S10, for example, whether or not there is a fire such as a cigarette or a lighter, whether or not the vehicle suddenly starts during refueling, whether or not the engine of the vehicle is stopped, and whether or not the refueling person is changed during refueling. Whether or not it is done, whether or not there is a person other than the refueling person during refueling, whether or not the discharge pipe 9A of the refueling nozzle 9 is shallowly inserted into the refueling port of the vehicle, the refueling person It is determined whether or not the refueling person is using a mobile phone, etc.

In this case, in S10, "there is the use of fire such as cigarettes and lighters", "the vehicle suddenly started during refueling", "the engine of the vehicle has not stopped (the engine has started)", and "refueling". "The refueling person is being replaced", "There is a person other than the refueling person during refueling", "The discharge pipe 9A of the refueling nozzle 9 is shallowly inserted into the refueling port of the vehicle", " If it is determined that "the refueling person is making extra observations during refueling" or "the refueling person is using a mobile phone", it is considered that there is an abnormality. Further, in S10, when it cannot be determined from the image (video) of the surveillance camera 22 whether it is normal or abnormal, it is determined to be unknown. If it is determined to be unknown, the process proceeds to S22 described later.

If it is determined in S10 that "NO", that is, there is no abnormality, the process proceeds to S11. In S11, it is determined whether or not the refueling nozzle 9 has been returned to the nozzle hook 11 (whether or not the nozzle switch 12 is ON). If it is determined in S11 that "NO", that is, the nozzle switch 12 is not ON (the refueling nozzle 9 has not been returned to the nozzle hook 11), the process returns to S10. On the other hand, if it is determined in S11 that "YES", that is, the nozzle switch 12 is ON (the refueling nozzle 9 is returned to the nozzle hook 11), the process proceeds to S12. In S12, the drive of the refueling pump 13 of the measuring machine 2 is stopped. In the following S13, it is determined that the refueling operation by the refueling person has been completed, and the process proceeds to the end. That is, the process returns to the start of FIG. 2 via the end of FIG. 3, and the processing after S1 is repeated.

On the other hand, if "YES" in S10, that is, if it is determined that there is an abnormality, the process proceeds to S14. In S14, the abnormality level is determined. That is, S14 determines the degree of abnormality. In the embodiment, the degree of abnormality is divided into three stages of "high", "medium", and "low". In this case, an abnormality with a high risk is defined as "high", an abnormality with a medium risk is defined as "medium", and an abnormality with a low risk is defined as "low". For example, if "there is the use of fire such as cigarettes or lighters", "the vehicle suddenly started during refueling", or "the vehicle's engine has not stopped (the engine has started)", refueling is stopped immediately. Since it is necessary to (emergency stop), it is regarded as a "high" abnormality. For example, "the refueling person is being replaced during refueling", "there is a person other than the refueling person during refueling", and "the discharge pipe 9A of the refueling nozzle 9 is shallowly inserted into the refueling port of the vehicle". If "yes", it is not necessary to stop refueling at this time, but there is a high possibility that it will develop into a dangerous state, so it is regarded as a "medium" abnormality. For example, if "the refueler is making extra observations while refueling" or "the refueler is using a mobile phone", it is unlikely that the situation will develop into a dangerous state, so it is "low" to alert the user. It is considered to be abnormal. In S14, it is determined to what level of abnormality the abnormality determined in S10 is, that is, which of "high", "medium", and "low" is the abnormality.

In S15 following S14, it is determined whether or not the level of abnormality is "high". If it is determined in S15 that the level of abnormality is "YES", that is, the level of abnormality is "high", an emergency stop process is performed so as not to cause damage in the gas station 1. That is, the process proceeds to S16 and the emergency stop process is issued. That is, in S16, when the emergency stop process is issued, the emergency stop signal is output from the management device 23 to the weighing machine 2, and in S17, the refueling pump of the measuring machine 2 is output based on the emergency stop signal from the management device 23. The drive of 13 is stopped. In the following S18, the abnormality is notified, and in S19, the refueling is forcibly terminated.

That is, in S18, the abnormality is notified in the state where the emergency stop is performed. Specifically, the fact that there is an abnormality having a high degree of danger is displayed on the screen of the management device 23, and the alarm lamp 24 of the measuring machine 2 is turned on. As a result, the staff and the refueling person are notified that there is a high-risk abnormality. In S19, the process of forcibly terminating refueling is performed. Specifically, in S19, the refueling person is notified to return the refueling nozzle 9 to the nozzle hook 11, and the refueling nozzle 9 is returned to the nozzle hook 11 to cancel the issuance of the emergency stop process. As a result, refueling is completed. That is, the process returns to the start of FIG. 2 via the end of FIG. 3, and the processing after S1 is repeated.

On the other hand, if it is determined in S15 that "NO", that is, the level of abnormality is not "high", the process proceeds to S20. In S20, it is determined whether or not the abnormality level is "medium". If "YES" in S20, that is, if the level of abnormality is determined to be "medium", the discharge flow rate of the refueling pump 13 is not necessary, but the discharge flow rate of the refueling pump 13 is suppressed in order to suppress the development into a dangerous state. Is temporarily lowered to make it possible to finish refueling at any time even though it is in a refueling state. That is, the process proceeds to S21 to notify the abnormality, and in the subsequent S22, the discharge flow rate of the refueling pump 13 is reduced.

In S21, an abnormality is notified in a state where refueling is continued. Specifically, the fact that the degree of danger is moderate is displayed on the screens of the monitor 23A of the management device 23 and the monitor device 18 of the weighing machine 2, and the speaker of the monitor device 18 outputs voice. This informs the staff and the refueling person that the risk is a moderate abnormality. In this case, it is preferable to notify the specific content of the abnormality, for example, by displaying "The insertion of the discharge pipe 9A of the refueling nozzle 9 is shallow" and outputting a voice. In S22, the management device 23 outputs a command to reduce the discharge flow rate to the measuring machine 2.

After notifying the abnormality in S21 and S22 and outputting a command to reduce the discharge flow rate, the process proceeds to S23. In S23, it is determined from the image of the surveillance camera 22 whether or not the abnormality has been resolved. That is, in S23, it is determined whether or not it is normal. If it is determined in S23 that it is "NO", that is, it is not normal (the abnormality has not been resolved), the process of S23 is repeated. That is, the state in which the discharge flow rate of the refueling pump 13 is reduced is maintained, and the necessary notification is continued. If "YES" in S23, that is, if it is determined to be normal (the abnormality has been resolved), the process proceeds to S24. In S24, the discharge flow rate of the refueling pump 13 is returned to the state before being reduced. That is, the management device 23 outputs a command to return the discharge flow rate to the measuring machine 2. After returning the discharge flow rate of the refueling pump 13 in S24, the process returns to S10 and the processing after S10 is repeated. The command to return the discharge flow rate may be output by the operation of a staff member. That is, the clerk may determine that the abnormality has been resolved, and the clerk may operate the management device 23 based on this determination to output a command for returning the discharge flow rate from the management device 23 to the measuring machine 2.

On the other hand, if it is determined in S20 that "NO", that is, the level of abnormality is not "medium", the process proceeds to S25. In S25, it is determined whether or not the level of abnormality is “low”. If it is determined in S25 to be "YES", that is, the level of abnormality is "low", the process proceeds to S26. In S26, the refueling person is alerted during the operation during refueling by using voice or the like. That is, it is displayed on the screen of the monitor device 18 of the measuring machine 2 that there is an abnormality having a low degree of danger, and further, audio is output from the speaker of the monitor device 18. In this case, it is preferable to notify the specific content of the abnormality, for example, by displaying "Please refrain from using a mobile phone" and outputting voice. In this case, the staff will not be notified. After notifying the refueling person in S26, the process returns to S10 and the processing after S10 is repeated. On the other hand, when it is determined in S25 that the level of abnormality is not "NO", that is, the level of abnormality is not "low", the process returns to S10 without going through S26, and the processing after S10 is repeated.

As described above, the gas station management system of the embodiment includes an abnormality determination means and a control means. The abnormality determination means corresponds to, for example, the processing of S10, S14, S15, S20, S23, S25 by the management device 23. The control means corresponds to, for example, the processing of S22 and S24 by the management device 23. The abnormality determining means determines the presence or absence of an abnormality in the gas station 1 from the situation detected by the monitoring camera 22 as the detecting means. That is, the abnormality determining means determines the presence or absence of an abnormality in the gas station 1 from the information (image, video) photographed by the surveillance camera 22 as the photographing means (detecting means). The control means changes the fuel supply amount by the measuring machine 2, specifically, the fuel supply speed or the flow rate, according to the determination result by the abnormality determination means. In this case, the abnormality determination means determines whether the monitoring camera 22 is normal, abnormal, or unknown, and if it is determined to be abnormal, determines the degree of the abnormality. That is, the abnormality determining means determines whether the image taken by the surveillance camera 22 is normal or abnormal, and if it is determined to be abnormal, the degree of the abnormality is determined. For example, when it is determined that there is an abnormality, the abnormality determining means determines which of the three stages of "high", "medium", and "low" the degree of the abnormality is.

The control means lowers the fuel supply speed or the flow rate by the measuring machine 2 from a preset value according to the degree of the abnormality determined by the abnormality determining means. That is, the control means is a measuring machine when the determination result by the abnormality determination means is unknown, or when the degree of abnormality is within a predetermined range set in advance (for example, when the degree of abnormality is "medium"). The fuel supply speed or flow rate according to 2 is lowered below the preset value. The "preset value" corresponds to, for example, the fuel supply speed or the flow rate when it is determined by the abnormality determination means that there is no abnormality. Further, when the control means determines that the abnormality is not abnormal (normal) after reducing the fuel supply speed or the flow rate by the measuring machine 2 based on the judgment result of the abnormality determining means, the measuring machine is used. Restore the fuel supply speed or flow rate according to 2.

According to such an embodiment, the management device 23 can change the fuel supply speed or the flow rate according to the determination result of the abnormality in the gas station 1 based on the image (image) of the surveillance camera 22. Therefore, it is possible to prevent a large amount of fuel from being discharged from the refueling nozzle due to an erroneous operation of the refueling person, and it is possible to improve safety at the time of refueling. Moreover, since the management device 23 determines the abnormality in the gas station 1 based on the image (image) of the surveillance camera 22, the abnormality can be determined more quickly than the staff member, and the abnormality is appropriate according to the abnormality. Processing (stopping of fuel supply, decrease, notification, etc.) can also be performed quickly. Further, since the management device 23 determines the abnormality in the gas station 1 based on the image (image) of the surveillance camera 22, even if the operation of the refueling person is difficult for the staff to determine the abnormality, "is it abnormal?" Whether or not it is possible and the degree of abnormality can be properly determined. As a result, the load (burden) of the staff member's abnormality judgment can be reduced. Further, since the monitor 23A of the management device 23 displays not only the live image (image) of the surveillance camera 22 but also the determination result of the abnormality by the AI of the management device 23 and the information at the time of the determination, the staff member can quickly perform the abnormality. You can know the contents of.

According to the embodiment, when the refueling person makes an erroneous operation, the management device 23 is operated by the measuring machine 2 according to the degree of the erroneous operation (in other words, the degree of abnormality in the gas station 1). The fuel supply rate or flow rate can be reduced. That is, when the abnormality determination result is unknown, the management device 23 reduces the fuel supply speed or flow rate by the measuring machine 2. Therefore, when the determination result is unknown, even if the refueling person makes an erroneous operation, a large amount of fuel is discharged from the refueling nozzle 9 because the fuel supply speed or the flow rate by the measuring machine 2 is low. It is possible to prevent it from being lost. For example, when the abnormality determination result is unknown, the refueling person operates the lever of the refueling nozzle 9 in a state where the discharge pipe 9A of the refueling nozzle 9 is not deeply inserted into the refueling port (lubricating port) of the fuel tank of the vehicle. Even so, it is possible to prevent a large amount of fuel from being discharged from the refueling nozzle 9. Further, when the degree of abnormality is "medium", the management device 23 reduces the fuel supply speed or flow rate by the measuring machine 2. In addition to this, the state in which the discharge pipe 9A of the refueling nozzle 9 is not deeply inserted into the refueling port of the fuel tank is set as a “medium” abnormality. Therefore, even if the refueling person operates the lever of the refueling nozzle 9 in a state where the discharge pipe 9A of the refueling nozzle 9 is not deeply inserted into the refueling port, the fuel supply speed or the flow rate by the measuring machine 2 decreases. , It is possible to prevent a large amount of fuel from being discharged from the refueling nozzle 9.

According to the embodiment, the management device 23 reduces the fuel supply speed or flow rate by the measuring machine 2, and then restores the fuel supply speed or flow rate by the measuring machine 2 when it is determined that there is no abnormality. Therefore, when it is determined that there is no abnormality, it is possible to prevent the state in which the fuel supply speed or the flow rate of the measuring machine 2 is lowered from being unnecessarily continued. As a result, the fuel can be efficiently supplied by the measuring machine 2.

According to the embodiment, even if the refueling permission signal is output from the management device 23 to the measuring machine 2 by the operation of the staff in the process of S8 in FIG. If it is determined that there is a "medium" abnormality, the fuel supply speed or flow rate is reduced. That is, even when the determination result (no abnormality) by the staff and the determination result (“medium” abnormality) by the management device 23 are different, the fuel supply speed or the flow rate can be reduced. As a result, safety during refueling can be improved from this aspect as well.

In the embodiment, the case where the degree of abnormality is divided into three stages of "high", "medium", and "low" has been described as an example. However, the degree of abnormality may be divided into, for example, two stages (for example, "abnormality of fuel supply stop" and "abnormality of fuel supply decrease"). Further, the degree of abnormality may be further subdivided into four or more stages. In either case, depending on the type and degree (risk) of the anomaly, whether to stop the fuel supply, reduce the fuel supply speed or flow rate, or keep the fuel supply speed or flow rate unchanged. Can be set. Further, depending on the type and degree of abnormality, the degree of decrease in fuel supply speed or flow rate may be changed. As a result, it is possible to prevent a large amount of fuel from being discharged from the refueling nozzle due to an erroneous operation of the refueling person.

In the embodiment, a case where the presence or absence of an abnormality in the gas station 1 is determined by using the information (video, image) of the surveillance camera 22 which is a photographing means has been described as an example. However, the present invention is not limited to this, and for example, it is detected not only by the information (video, image) of the surveillance camera 22 but also by various sensors (detectors) that detect sound, temperature, light, steam concentration, etc. as the situation in the refueling station. The information (sound, temperature, light, fuel vapor concentration, etc. in the refueling station) may also be used to determine the presence or absence of an abnormality in the refueling station 1. That is, the gas station management system shall be configured to include a detection means for detecting the situation in the gas station including the photographing means and an abnormality determination means for determining the presence or absence of an abnormality in the gas station from the situation detected by the detection means. Can be done. The detection means can be configured to include at least a camera (shooting means) among various cameras and various sensors. Further, the detection means may be configured not to include a camera (shooting means). That is, the detection means may be configured by various sensors without including a camera (shooting means).

In the embodiment, a case where an abnormality is displayed on the screen of the management device 23 as an example of notifying the staff member of the abnormality performed in the process of S21 has been described. However, the present invention is not limited to this, and for example, an abnormality may be displayed on the screen of a mobile information terminal such as a tablet terminal or a smartphone owned by a staff member. That is, the notification to the staff may be performed using the management device or the information terminal carried by the staff.

In the embodiment, as an abnormality in the gas station 1, whether or not the refueling person touches the static electricity removing sheet 21, whether or not the discharge pipe 9A of the refueling nozzle 9 is inserted into the refueling port of the vehicle, and whether or not the refueling nozzle 9 is discharged. Whether the pipe 9A is shallowly inserted into the fuel filler port of the vehicle, whether fire such as cigarettes or lighters is used, whether the vehicle suddenly started during refueling, and whether the engine of the vehicle is stopped. Whether or not (whether or not the engine has been started), whether or not the refueling person has been replaced during refueling, whether or not there is a person other than the refueling person, and whether or not the refueling person has made extra observations during refueling. The case where it is configured to determine whether or not the refueling person is using a mobile phone has been described as an example. However, the present invention is not limited to this, and as an abnormality in the refueling station, it may be determined, for example, whether or not refueling is performed by a child, in addition to the above. That is, the abnormality in the refueling station is not limited to the above, and various unfavorable situations (abnormalities) in the refueling station can be determined.

In the embodiment, as the measuring machine 2, a ground-mounted refueling device (fuel supply device) has been described as an example. However, the present invention is not limited to this, and for example, a suspension type refueling device that raises and lowers the refueling nozzle may be used as a measuring machine.

In the embodiment, the fuel tank of the vehicle has been described as an example as the fuel supply body (fuel supply target) to which the measuring machine 2 supplies fuel. However, the present invention is not limited to this, and the measuring instrument serving as the fuel supply device may supply fuel to a fuel supply body other than the fuel tank of the vehicle, such as a gasoline carrying can or a plastic tank.

In the embodiment, the weighing machine 2 installed at the gas station (service station) has been described as an example. However, the present invention is not limited to this, and the measuring machine serving as a fuel supply device may be installed at a refueling station other than a gas station (service station) such as a factory, a store, or a home center.

Further, in the embodiment, the management device 23 is provided in the management building (not shown) on the premises of the gas station 1, and the staff (refueling manager) monitors refueling and transmits a permission signal from the management building. The case of doing this was explained as an example. However, not limited to this, for example, a management device is installed in an office other than the site of the gas station, and a staff member (refueling manager) monitors refueling and sends a permission signal from within the office. You may. In addition, a management device will be installed in the management building on the premises of the gas station, and the AI judgment result (analysis result) will be used to monitor refueling, send permission signals, etc., and the staff (refueling manager) will be in a place other than the management building. You may monitor the gas station from. Furthermore, no management device is installed in offices other than the site of the gas station, and the AI judgment result (analysis result) is used to monitor refueling, send a permit signal, etc., and the staff (refueling manager) is other than the management building. You may monitor the gas station from the location of.

As the gas station management system based on the embodiment described above, for example, the one described below can be considered.

As a first aspect, a detection means for detecting a situation in a gas station in a gas station management system including a measuring machine for supplying fuel to a vehicle and a management machine for managing the fuel supply by the measuring machine. An abnormality determining means for determining the presence or absence of an abnormality in the gas station based on the situation detected by the detecting means, and a control for varying the fuel supply speed or the flow rate by the measuring machine according to the determination result by the abnormality determining means. It has the means.

According to this first aspect, the control means can change the fuel supply speed or the flow rate according to the determination result by the abnormality determination means. Therefore, it is possible to prevent a large amount of fuel from being discharged from the refueling nozzle due to an erroneous operation of the refueling person, and it is possible to improve safety at the time of refueling.

As a second aspect, in the first aspect, the abnormality determining means determines whether the detection means is normal or abnormal, and if it is determined to be abnormal, the degree of the abnormality. The control means reduces the fuel supply speed or the flow rate of the fuel by the measuring machine from a preset value according to the degree of the abnormality determined by the abnormality determining means.

According to this second aspect, the control means reduces the fuel supply speed or the flow rate by the measuring machine according to the degree of the abnormality determined by the abnormality determining means. Therefore, when the refueler makes an erroneous operation, the fuel supply speed or flow rate by the measuring machine decreases according to the degree of the erroneous operation (degree of abnormality), so that a large amount of fuel is supplied from the refueling nozzle. It is possible to suppress the discharge.

As a third aspect, in the first aspect or the second aspect, the control means reduces the fuel supply speed or the flow rate by the measuring machine based on the determination result of the abnormality determination means, and then the control means. If it is determined by the abnormality determination means that there is no abnormality, the fuel supply speed or flow rate by the measuring machine is restored. According to this third aspect, when it is determined by the abnormality determining means that there is no abnormality, it is possible to prevent the state in which the fuel supply speed or the flow rate of the measuring machine is lowered from being unnecessarily continued. As a result, the fuel can be efficiently supplied by the measuring machine.
