Further, the main monitor 5B of the management device 5 and the monitor 8 of the mobile terminal 7 display the determination result of the presence or absence of abnormality in the gas station 1 by the abnormality determination means 9 as necessary. Here, the numbers "01" to "08" in FIG. 2 correspond to the identification numbers individually given to the plurality of fueling machines ₂₁ to ₂₈ , respectively. In other words, the numbers “01” to “08” correspond to the numbers of the refueling lanes in which the refueling machines 2 ₁ to 2 ₈ are respectively provided.

A list screen (the screen shown in FIG. 2) collectively displays the operation statuses of all the fueling machines 2 ₁ to 2 ₈ . _{On the other} hand, the detailed screen ₍ Fig. 3) is displayed. On the detailed screen (FIG. 3), it is possible to display the judgment result (for example, "nozzle insertion OK") of one fueling machine 2 ₁ to 2 ₈ judged by the abnormality judging means 9. FIG. Further, the detailed screen (FIG. 3) can display the set oil type and oil supply amount (for example, "regular", etc.). The determination result determined by the abnormality determining means 9 and/or the set oil type and oil supply amount may be displayed on a list screen (FIG. 2).

The list screen in FIG. 2 and the detailed screen in FIG. 3 are updated to the latest information by the display control means 10, which will be described later. In addition, the mobile terminal 7 can be operated by a staff member touching the monitor 8 (for example, by touching the "permission" button 8H (FIG. 3) or the selection buttons 8A ₁ to 8A ₈ (FIG. 2) displayed on the monitor 8 to allow refueling. A permission signal, a screen switching signal, or the like can be transmitted to the management apparatus 5 by touching the screen with a fingertip or a pen.

The list screen in _FIG . 2 includes, for example, selection buttons 8A ₁ to 8A ₈ individually corresponding to the refueling machines _{2 1 to} 2 ₈ and a "simultaneous A "stop" button 8B, a "stop" button 8C for stopping the refueling operation of the refueling machine 2 ₁ to 2 ₈ selected from the refueling machines 2 ₁ to 2 ₈ , and a staff member performing work such as confirmation of abnormality. A "Confirm" button 8D to be operated (pressed) when performing (or performing) is displayed. The selection buttons 8A ₁ to 8A ₈ are displayed as rectangular display areas partitioned for each of the fuel tankers 2 ₁ to 2 ₈ , and when the display area is touched by the staff, a selection signal (screen switching signal, etc.) is generated. is sent to the management device 5 . The information included in the selection signal here includes, for example, "the ID of the mobile terminal, the No. of the refueling machine, and the state of the refueling machine."

For example, when the staff member wants to switch from the list screen (Fig. 2) to the detailed screen (Fig. 3) of No. 8 (NO.08) refueling machine ₂₈ , the selection button 8A for No. 8 (NO.08) in the list screen is pressed. Touch (specify, press) ₈ . By this operation, the screen of the portable terminal 7 is switched from the list screen to the detailed screen of the refueling machine ₂₈ of No. 8 (NO.08). In addition, if you touch (specify, press) the selection button 8A ₈ of No. 8 (NO. No. 08), the detailed screen of the refueling machine ₂₈ may be displayed.

Further, the selection buttons 8A ₁ to 8A ₈ have icons 12 in the _shape of "nozzles" as shown in the first and third selection buttons 8A ₁ and 8A ₃ . An icon 12 (hereinafter referred to as a nozzle icon 12) can be displayed to indicate that the nozzle has been removed. For this reason, each of the fuel dispensers 2 ₁ to 2 ₈ is provided with a nozzle sensor as detection means (nozzle detection means) for detecting that the fuel nozzle 2B has been removed from the fuel dispensers 2 ₁ to 2 ₈ . . The nozzle sensor can be composed of, for example, a two-position switching type switch capable of detecting the presence or absence of the fuel nozzle 2B. For example, when the fueling nozzle 2B is hooked to the fueling machines 2 ₁ to 2 ₈ and pushed by the fueling nozzle 2B, the nozzle sensor is turned on (ON), and the fueling nozzle 2B is engaged with the fueling machines 2 ₁ to 2 ₈ . It can be configured to switch off when removed from. The nozzle sensors are connected to controllers of the fuel dispensers 2 ₁ to 2 ₈ .

A detection result of the nozzle sensor is input to the management device 5 . That is, when a signal corresponding to OFF is input from the nozzle sensor, the controller of the refueling machines 2 ₁ to 2 ₈ transmits (outputs) a signal to that effect (refueling permission request signal) to the management device 5. do. Based on the signals from the controllers of the refueling machines 2 ₁ to 2 ₈ , the management device 5 displays nozzle icons 12 on the selection buttons 8A ₁ to 8A ₈ corresponding to the refueling machines 2 ₁ to 2 ₈ from which the refueling nozzle 2B has been removed. display. More specifically, the information stored in the storage device 5A of the management device 5 is updated to "nozzle icon present", and based on this update, the display screens of the monitor 8 of the mobile terminal 7 and the main monitor 5B of the management device 5 are displayed. is updated. As a result, when the nozzle sensor detects that the fuel nozzle 2B has been removed, the management device 5 can notify that the fuel nozzle 2B has been removed on the list screen.

In addition to the nozzle icon 12, the selection buttons 8A ₁ to 8A ₈ also display an icon 13 indicating that fuel is being supplied (hereinafter referred to as a fueling icon 13), an icon indicating that fueling is temporarily stopped (not shown), and the like. can do. For example, as shown in FIG. 2, the refueling icon ₁₃ is displayed on the No. 6 selection button 8A6. This indicates that the No. 6 refueling machine ₂₁ is refueling. Further, for example, when it is determined that there is an abnormality in the refueling machines 2 ₁ to 2 ₈ by the abnormality determination means 9 to be described later, the selection buttons 8A ₁ to 8A ₈ of the refueling machines 2 ₁ to 2 ₈ determined to be abnormal The display area can also be displayed in red. As a result, the person in charge can grasp that an abnormality has occurred in the refueling machines 2 ₁ to 2 ₈ .

The detailed screen of FIG. 3 includes, for example, a "stop all" button 8B, a "stop" button 8C, and an "permit" button 8H on the list screen, as well as one specified when switching to the detailed screen. An image display section 8E displaying a video (image) of the refueling lane including the refueling machines 2 ₁ to 2 ₈ of the above, a refueling state display section 8F displayed on the upper side of the image display section 8E, and a lower side of the image display section 8E can be displayed. The detailed screen can also display the type of oil, the amount of oil to be supplied, and the like. The detailed screen of FIG. 3 corresponds to the detailed screen of the first fuel dispenser _2-1 , and a nozzle icon 12 indicating that the fuel nozzle 2B has been removed from the fuel dispenser _2-1 is displayed in the fuel supply status display area 8F. ing. Further, since the abnormality determination means 9 has determined that the fuel nozzle 2B is properly inserted, "nozzle insertion OK" is displayed in the abnormality determination result display section 8G.

Here, for example, when the abnormality determination means 9 determines that there is an abnormality (when the abnormality determination result is Danger or Caution), a confirmation button 8D is displayed instead of the permission button 8H. At this time, the video (image) judged to be abnormal by the abnormality judgment means 9 is displayed on the image display section 8E. Further, the contents of the abnormality such as "nozzle insertion failure" are displayed in the abnormality determination result display section 8G. It should be noted that the detailed screen described above is an example, and the layout, the number of displays, and the like are not limited to this.

In the refueling state display section 8F, as the operation status of the refueling machines 2 ₁ to 2 ₈ , "waiting" waiting for the vehicle 101, and "refueling" after the refueling person sets the refueling amount etc. with the setting device 2D. "Waiting", "Waiting for permission" waiting for permission to refuel by the staff member after the refueling nozzle 2B is removed, "Refueling" during refueling, etc. can be displayed by characters or icons. Also, in the abnormality determination result display section 8G, danger items such as "smoking" and "nozzle insertion failure", caution items such as "refueler's mobile phone use", and whether the refueling nozzle 2B is correctly inserted into the refueling port 102 are displayed. Items including normal items such as "nozzle insertion OK" and "no detection" in which the operating status of the refueling machines ₂₁ to ₂₈ cannot be detected due to equipment failure, etc., can be displayed with characters or icons. can.

When the abnormality determining means 9 determines that there is an abnormality, the staff can confirm the status of the abnormality from the video (image) on the image display section 8E. At this time, the "permit" button 8H in FIG. 3 is replaced with the "confirm" button 8D. This "confirmation" button 8D is pressed (touched) when the staff determines that there is no abnormality in the fuel dispensers ₂₁ to ₂₈ from the video (image) displayed on the image display section 8E. When the "confirm" button 8D is pressed, it is determined that the abnormality has been resolved, and the "confirm" button 8D is switched to the "permit" button 8H for permitting refueling.

The abnormality determination means 9 is built in the management device 5, for example. The abnormality determination means 9 determines whether or not an abnormality has occurred in the gas station 1 based on the information of the videos (images) captured by the surveillance cameras 3 ₁ to 3 _n . Specifically, the abnormality determination means 9 uses videos (images) of the refueling work in the refueling lane captured by the surveillance cameras 3 ₁ to 3 _n and a trained model that has learned the correct refueling work in advance, If the correct lubrication work cannot be detected, it is judged to be abnormal. That is, the abnormality determination means 9 determines the presence or absence of abnormality by image recognition technology based on AI (artificial intelligence) machine learning.

In this case, the AI determines whether there is an abnormality in the refueling work based on information such as the action of the refueling person, the position of the refueling port 102 of the vehicle 101, the position of the refueling nozzle 2B, and the orientation of the refueling nozzle 2B. In some cases, the abnormality determination means 9 cannot determine the presence or absence of an abnormality from comparison with a pre-learned correct refueling work video (image). As a result, the abnormality determination means 9 can determine any one of "danger level", "caution level", and "normal level" when determining abnormality. In addition to the above, the abnormality determination means 9 also determines whether or not there is an abnormality in the refueling machines 2 ₁ to 2 ₈ and each device in the refueling station 1 .

The display control means 10 is built in the management device 5, for example. The display control means 10 causes the main monitor 5B of the management device 5 and the monitor 8 of the portable terminal 7 to display a list screen (FIG. 2) or a detailed screen (FIG. 3). Also, the display control means 10 updates the display contents of the list screen (FIG. 2) or the detailed screen (FIG. 3) to the latest information. In addition, the display control means 10 displays the information used when the abnormality determination means 9 determines whether or not there is an abnormality in the refueling lane and the determination result by the abnormality determination means 9 on the list screen (Fig. 2) or the detailed screen (Fig. 3). display.

Specifically, the display control means 10 collectively displays the operation status of each of the plurality of refueling machines 2 ₁ to 2 ₈ (that is, each refueling lane) on the list screen of FIG. Further, the display control means 10 causes the image display section 8E of the monitor 8 to display the videos (images) captured by the monitoring cameras 3 _{1 to} 3 _n on the detailed screen of _FIG . The operation status of (fueling lane) is displayed on the fueling status display section 8F. Along with this, on the detailed screen of FIG. 3, the presence or absence of an abnormality in the specified refueling machine 2 ₁ to 2 ₈ (refueling lane), that is, the result determined by the abnormality determining means 9 is displayed on the abnormality determination result display section 8G.

Further, the display _control means 10, for _example , on the list screen in _{FIG .} is displayed in red. As a result, it is possible to notify the refueling machines 2 ₁ to 2 ₈ (refueling lanes) determined to be abnormal. On the other hand, when the abnormality determination means 9 determines that there is no abnormality (abnormality does not occur), the display control means 10 displays the selection buttons 8A ₁ to 8A ₈ on the list screen in green, for example. . As a result, the person in charge can easily grasp what kind of judgment is made by the abnormality judging means 9 .

The refueling control means 11 transmits to the refueling machines 2 ₁ to 2 ₈ a refueling permission signal for permitting refueling by the refueling machines 2 ₁ to 2 ₈ . That is, when the clerk presses the "permission" button 8H for permitting refueling displayed on the detailed screen (FIG. 4) of the monitor 8, the portable terminal 7 transmits a signal to that effect (permission signal). Send to the management device 5 . The refueling control means 11 of the management device 5 transmits a refueling permission signal permitting refueling to the refueling machines 2 ₁ to 2 ₈ when receiving the signal (permission signal) transmitted from the mobile terminal 7 . Refueling machines 2 ₁ to 2 ₈ that have received this refueling permission signal are enabled to drive refueling pumps (not shown). As a result, it is possible to refuel the object to be refueled by the refueling machines 2 ₁ to 2 ₈ . Permission for such refueling can be given not only from the mobile terminal 7 but also from the management device 5 .

By the way, at the self-service gas station 1, a plurality of staff members each carry a mobile terminal 7, and from the images of the monitoring cameras 3 ₁ to 3 _n displayed on the screen of the mobile terminal 7, the refueling waiting for refueling permission can be confirmed. It is conceivable to check the state of the machines 2 ₁ to 2 ₈ (safety for refueling, such as whether the refueling nozzle 2B is inserted into the refueling port 102) and permit refueling using the portable terminal 7. be done. However, if each staff member cannot grasp which staff member is checking which tanker 2 ₁ to 2 ₈ , there is a possibility that the same tanker 2 ₁ to 2 ₈ will be checked redundantly.

This is inefficient. Therefore, in the embodiment, the portable terminal 7 of another attendant can recognize that one of the attendants is monitoring the fuel dispensers 2 ₁ to 2 ₈ with the portable terminal 7 . As a result, staff members can understand each other's work status and reduce duplication of work. These points will be described below.

That is, the fueling station 1 of the embodiment includes a plurality of fueling machines 2 ₁ to 2 ₈ that refuel a vehicle 101, and a management system that is communicably connected to these fueling machines 2 ₁ to 2 ₈ and controls whether fueling is permitted or not. It comprises a device 5 and a plurality of portable terminals 7 which are communicatively connected to the management device 5 and perform operations regarding permission to refuel to the refueling machines 2 ₁ to 2 ₈ . The management device 5 and the mobile terminal 7 are management machines that manage refueling by the refueling machines 2 ₁ to 2 ₈ (more specifically, manage permission or non-permission of refueling).

On the display screens of the management device 5 and the mobile terminal 7, a list screen as shown in FIG. 2 and a detailed screen as shown in FIG. 3 are displayed so as to be switchable. On the list screen of FIG. 2, the state of each refueling machine 2 ₁ to 2 ₈ (for example, standby, refueling waiting, permission waiting, refueling in progress, refueling stopped, etc.) can be selected for each refueling machine 2 ₁ to 2 ₈ . Displayed within buttons 8A ₁ to 8A ₈ . When the staff presses the selection buttons 8A ₁ to 8A ₈ , the display screen switches from the list screen in FIG. 2 to the detailed screen in FIG. 3 . Note that switching from the list screen in FIG. 2 to the detailed screen in FIG. 3 can be done by, for example, pressing the selection buttons 8A ₁ to 8A ₈ and pressing the "confirm" button 8D. good.

In any case, in the embodiment, one of the staff members (for example, three staff members A, B, and C) (for example, A) displays the list screen of the mobile terminal 7 that he/she carries ( When one of the selection buttons 8A ₁ to 8A ₈ in FIG. 2) is pressed, an icon 14 to that effect is displayed on the list screen of the mobile terminals 7 carried by other staff members (eg, B, C). That is, on the list screen of the mobile terminal 7 of the other staff member (for example, B, C), the staff member (for example, A) among the pressed selection buttons 8A ₁ to 8A ₈ has the selection button 8A ₁ to 8A. An icon 14 (hereinafter referred to as confirmation icon 14) indicating that the fueling machines 2 ₁ to 2 ₈ corresponding to ₈ are confirmed is displayed.

The confirmation icon 14 can be, for example, the identification symbol or identification number of the pressed portable terminal 7, or the name of the person in charge who performed the operation. In FIG. 2 , “A” and “B” are displayed as the confirmation icon 14 , and “A” and “B” correspond to the identification symbols of the portable terminal 7 . For example, there are three mobile terminals 7, A, B, and C. Staff A uses A's mobile terminal 7, staff B uses B's mobile terminal 7, and staff C uses C's mobile terminal. Consider the case where the user has (carries) 7. In this case, when staff member A presses the selection button 8A ₁ on the list screen of A's mobile terminal 7, that is, the selection button 8A ₁ of "01", the mobile terminals of other staff members B and C A confirmation icon 14 of “A” is displayed in the selection button _8A1 of the list screen of the machine 7 . Therefore, other staff (for example, B and C) can understand that staff A is checking (responsible for) the refueling machine 2 ₁ (fueling lane) of "01" (or what he did). .

Further, when the staff member B presses the selection button 8A ₆ of the list screen of the mobile terminal 7 of B, that is, the selection button 8A ₆ of "06", the mobile terminals of the other staff members A and C The confirmation icon 14 of "B" is displayed in the selection button _8A6 of the list screen of the machine 7. As shown in FIG. Therefore, other staff members (for example, A and C) can understand that staff member B is in charge of checking (responsible for) the refueling machine 2 ₆ (fueling lane) of "06" (or what he did). . As a result, it is possible to prevent two or more staff members from redundantly confirming the same tanker 2 ₁ to 2 ₈ (the first tanker 2 ₁ and the sixth tanker 2 ₆ ).

As described above, the gas station 1 of the embodiment has a fueling management system that manages a plurality of fueling machines 2 ₁ to 2 ₈ (for example, management of permission or non-permission of fueling). The refueling management system includes a plurality of mobile terminals 7 and a management device 5, each serving as a management device, and a plurality of refueling machines 2 ₁ to 2 ₈ . In the embodiment, the configuration includes three mobile terminals 7, one management device 5, and eight refueling machines 2 ₁ to 2 ₈ , but the present invention is not limited to this. The refueling management system uses the portable terminal 7 and the management device 5 to refuel from the refueling machines 2 ₁ to 2 ₈ to refueling objects (for example, the vehicle 101, fuel cans, plastic tanks, etc.). In this case, the refueling management system notifies other portable terminals that confirmation operation has been performed on the specific refueling machine 2 ₁ to 2 ₈ regarding the refueling work using one portable terminal 7 (or management device 5). 7 (or management device 5).

More specifically, the display screens of the mobile terminal 7 and the management device 5 include a "list screen (FIG. 2)" that displays the fueling status of the plurality of fueling machines ₂₁ to ₂₈ , and a list of specific fueling machines ₂₁ to A "detailed screen (Fig. 3)" that displays the refueling status of ₂₈ can be switched and displayed. Then, the management device 5 assumes that the confirmation operation for the specific refueling machines 2 ₁ to 2 ₈ is performed by operating the selection buttons 8A ₁ to 8A ₈ corresponding to the confirmation buttons displayed on the list screen. In this case, the management device 5 displays the mobile terminal 7 (or the management device 5) on the list screen of the mobile terminals 7 (or the management device 5) other than the mobile terminal 7 (or the management device 5) for which the confirmation operation has been performed. ) to display that the confirmation operation has been performed. As shown in FIG. 2, on the list screen of the mobile terminals 7 (or the management device 5) other than the mobile terminal 7 (or the management device 5) for which the confirmation operation has been performed, as an indication that the confirmation operation has been performed, A confirmation icon 14 is displayed within the selection button 8A ₁ (or selection button 8A ₆ ) corresponding to the particular tanker 2 1 ₍ or tanker 2 ₆ ). Thus, in the embodiment, the confirmation buttons are the selection buttons 8A ₁ to 8A ₈ displayed on the list screen corresponding to the plurality of fuel dispensers 2 ₁ to 2 ₈ , respectively. The selection buttons 8A ₁ to 8A ₈ are buttons that are operated when switching from the list screen to a detailed screen of a specific fueling machine 2 ₁ to 2 ₈ .

Further, each fuel dispenser 2 ₁ to 2 ₈ has a nozzle sensor as detection means for detecting that the fuel filler nozzle 2B is removed from the fuel dispenser 2 ₁ to 2 ₈ . When the nozzle sensor detects that the fuel nozzle 2B has been removed, the management device 5 notifies that the fuel nozzle 2B has been removed by displaying the nozzle icon 12 on the list screen. In this case, the refueling machines 2 ₁ to 2 ₈ from which the refueling nozzle 2B has been removed are notified. For this reason, the selection buttons 8A ₁ to 8A ₈ have the refueling nozzles 2B removed when the refueling nozzles 2B of the refueling machines 2 ₁ to 2 ₈ corresponding to the selection buttons 8A ₁ to 8A ₈ are removed. A nozzle icon 12 corresponding to that is displayed. Furthermore, the management device 5 includes an abnormality determination means 9 as determination means for determining whether or not there is an abnormality in the gas station 1 from images (videos) of the monitoring cameras 3 ₁ to 3 _n as cameras that capture the inside of the gas station 1 . I have it. The management device 5 can also display the judgment result by the abnormality judging means 9 on the list screen. In this case, the selection buttons 8A ₁ to 8A ₈ display the determination results of the abnormality determination means 9 of the fueling machines 2 ₁ to 2 ₈ corresponding to the selection buttons 8A ₁ to 8A ₈ .

Next, the flow charts (flow charts) shown in FIGS. 4 to 8 will be described. FIG. 4 is a flow chart (flowchart) showing control processing performed by the fueling machines 2 ₁ to 2 ₈ . 5 and 7 are flow charts (flowcharts) showing the control processing performed by the management device 5. FIG. 6 and 8 are flow charts (flowcharts) showing control processing performed by the mobile terminal 7. FIG. The processes of FIGS. 4 to 8 are repeatedly executed at a predetermined control cycle.

First, the processing performed by the fueling machines 2 ₁ to 2 ₈ shown in FIG. 4, more specifically, the processing performed by the control device incorporated in the fueling machines 2 ₁ to 2 ₈ will be described. The control process shown in FIG. 4 is started, for example, when the vehicle 101 enters the fuel lane. When the process of FIG. 4 is started, in S1, it is determined whether or not the refueling setting by the refueling person has been completed. That is, in S1, the fueling person uses the setting device 2D of the fueling machines 2 ₁ to 2 ₈ to select the payment method, select the oil type, select full tank fueling, select any preset fueling amount, etc., and start fueling. Determine whether the previous setting is complete. If it is determined "NO" in S1, that is, if it is determined that the setting of refueling by the refueling person has not been completed, the process of S1 is repeated. On the other hand, if "YES" in S1, that is, if it is determined that the refueling setting by the refueling person has been completed, the process proceeds to S2.

In S<b>2 , a fueling setting completion signal, which is a signal indicating that the fueling setting has been completed, is transmitted (output) to the management device 5 . That is, the refueling machines 2 ₁ to 2 ₈ that have completed the refueling setting transmit a refueling setting completion signal to the management device 5 . In S3 following S2, it is determined whether or not the fuel nozzle 2B has been removed from the fuel dispensers 2 ₁ to 2 ₈ . This determination can be made depending on whether the nozzle sensor (nozzle switch) is OFF or ON. That is, in S3, it is determined whether or not the nozzle sensor (nozzle switch) is "off" corresponding to the OFF state of the nozzle sensor.

If it is determined "NO" in S3, that is, if it is not "refueling nozzle OFF", it is "refueling nozzle ON" corresponding to the state in which the nozzle sensor (nozzle switch) is ON. In this case, the nozzle sensor (nozzle switch) is ON and the fuel nozzle 2B is not removed from the fuel dispensers 2 ₁ -2 ₈ . For this reason, when the determination in S3 is "NO", the processing in S3 is repeated. On the other hand, if "YES" in S3, that is, if it is determined that the "fueling nozzle is OFF", the nozzle sensor (nozzle switch) is OFF. In this case, since the fuel nozzle 2B has been removed from the fuel dispensers 2 ₁ to 2 ₈ , the process proceeds to S4. In S<b>4 , a refueling permission request signal, which is a signal requesting permission of refueling to the person in charge, is transmitted (output) to the management device 5 . That is, the refueling machines 2 ₁ to 2 ₈ from which the refueling nozzle 2B is removed transmit a refueling permission request signal to the management device 5 .

In S5 following S4, it is determined whether or not a fuel supply permission signal has been received. That is, in S5, it is determined whether or not a fueling permission signal for permitting fueling by the fueling machines 2 ₁ to 2 ₈ from which the fueling nozzle 2B has been removed has been received from the management device 5 . If "NO" in S5, that is, if it is determined that the refueling permission signal has not been received from the management device 5, the process of S5 is repeated. On the other hand, if "YES" in S5, that is, if it is determined that the fueling permission signal has been received from the management device 5, the process proceeds to S6. In S6, the fuel pump is driven. That is, in S6, fuel can be supplied by the fuel dispensers 2 ₁ to 2 ₈ from which the fuel nozzle 2B has been removed. As a result, the refueling person can refuel the fuel tank of the vehicle 101 according to the lever operation of the refueling nozzle 2B.

In S7 following S6, it is determined whether or not the fuel nozzle 2B has been returned to the fuel dispensers 2 ₁ to 2 ₈ . That is, in S7, it is determined whether or not the nozzle sensor (nozzle switch) is "on" corresponding to the ON state of the nozzle sensor. If it is determined “NO” in S7, that is, if it is not “on”, the fuel nozzle 2B is not returned to the fuel dispensers 2 ₁ to 2 ₈ . In this case, the process of S7 is repeated. On the other hand, if it is determined "YES" in S7, ie, "fueling nozzle ON", the fueling nozzle 2B has been returned to the fueling machines 2 ₁ to 2 ₈ , so the process proceeds to S8. In S8, the fuel pump is stopped, and in subsequent S9, a fueling end signal, which is a signal indicating that fueling has ended, is transmitted (output) to the management device 5. FIG. That is, the refueling machines 2 ₁ to 2 ₈ that have finished refueling transmit a refueling end signal to the management device 5 . When the fueling end signal is transmitted to the management device 5 in S9, the process is terminated. That is, the process returns to the start via the end, and repeats the processes after S1.

Next, processing performed by the management device 5 shown in FIG. 5 will be described. The control process shown in FIG. 5 is started, for example, when the management device 5 is activated. When the process of FIG. 5 is started, in S11, it is determined whether or not a fueling setting completion signal has been received from the fueling machines 2 ₁ to 2 ₈ . If "YES" in S11, that is, if it is determined that the fueling setting completion signal has been received from the fueling machines 2 ₁ to 2 ₈ , the process proceeds to S12. In S12, the information in the storage device 5A (storage means) of the management device 5 is updated.

That is, as shown in FIG. 10, the storage device 5A (storage means) of the management device 5 stores the “state” of the fueling machines _{2 1 to 2 8 ,} nozzle Whether or not the icon 12 is displayed, whether or not the confirmation icon 14 is displayed, and whether or not there is an update are stored in an updatable manner. These pieces of information correspond to information (display screen information) displayed on the main monitor 5B of the management device 5 (and the monitor 8 of the mobile terminal 7). As shown in FIG. 10, in the storage device 5A of the management device 5, monitors are stored corresponding to the mobile terminals 7, that is, the mobile terminals 7 of "A", "B", and "C".

These pieces of information correspond to information about the mobile terminal 7 . In FIG. 10, the staff member who possesses the portable terminal 7 of "A" is designated as "A", the staff member who possesses the portable terminal device 7 of "B" is designated as "B", and the portable terminal device 7 of "C" is designated. The person in charge is called "Hei".

As described above, in the embodiment, the management device 5 stores the correspondence relationship between the attendant and the portable terminal 7 in the storage device 5A so that the attendant can grasp which portable terminal 7 is being operated (possessed). be. That is, the person who operates the mobile terminal 7 can be managed by the person in charge operating the mobile terminal 7 (specifically, selecting the number associated with the name of the person in charge). The device 5 is designed to be able to grasp it. For example, each attendant is assigned an ID (identification symbol such as a number, alphabet, etc.) for logging in to the mobile terminal 7. By logging in to the mobile terminal 7 with this ID, the attendant and the mobile phone can communicate with each other. The terminal device 7 can be linked. In addition, for example, the owner (name) of each mobile terminal 7 may be stored (registered) in advance so that it is possible to grasp which mobile terminal 7 is currently owned by which staff member. good.

Accordingly, in the embodiment, the login status and refueling permission status of the mobile terminal 7 can be managed by the management device 5 . In this case, the management device 5 can also store which attendant used which mobile terminal 7 to give permission to refuel. That is, in the embodiment, the mobile terminal 7 and the attendant are each associated with an ID. In this case, for example, by the login function performed before the clerk starts operating the mobile terminal 7, the mobile terminal 7 and the clerk (name of the clerk) of the logged-in ID can be linked. As described above, in the embodiment, the login status and refueling permission status of the mobile terminal 7 are stored in the management device 5, and it is configured to be able to store who used which mobile terminal 7 to refuel. there is

In S12 of FIG. 5, the information in the storage device 5A of the management device 5 is changed to "waiting for refueling", _specifically , _the "state ” to “Waiting for refueling”. For example, when the fueling setting completion signal is received from the fueling machine ₂₇ numbered ₇ , as shown in FIG. In addition, since the "state" information has been updated by this, the "update" of the refueling machine ₂₇ of "07" is set to "yes". After updating the information in the storage device 5A of the management device 5 in S12, the process returns. That is, the process returns to START via RETURN, and repeats the processes after S11.

On the other hand, if it is determined "NO" in S11, that is, if it is determined that the fueling setting completion signal has not been received from the fueling machines 2 ₁ to 2 ₈ , the process proceeds to S13. In S13, it is determined whether or not a refueling permission request signal has been received from the refueling machines 2 ₁ to 2 ₈ . If "YES" in S13, that is, if it is determined that the refueling permission request signal has been received from the refueling machines 2 ₁ to 2 ₈ , the process proceeds to S14. In S14, the information in the storage device 5A of the management device 5 is updated. That is, in S14, the "status" of the refueling machines ₂₁ to ₂₈ that have transmitted (output) the refueling permission request signal to the management device 5 is updated to "waiting for permission", and the "nozzle icon display" is changed to "nozzle icon Update to Yes. For example, when a refueling permission request signal is received from refueling machine 2-3 _{No. 3} , as shown in FIG. , update "Nozzle icon display" to "Yes". Since the information of "state" and "nozzle icon display" is updated by this, "update" of the refueling machine ₂₃ of "03" is set to "yes". After updating the information in the storage device 5A of the management device 5 in S14, the process returns.

On the other hand, if it is determined "NO" in S13, that is, if it is determined that the fueling permission request signal has not been received from the fueling machines 2 ₁ to 2 ₈ , the process proceeds to S15. In S15, it is determined whether or not a selection signal has been received from the portable terminal 7. FIG. If "YES" in S15, that is, if it is determined that the selection signal has been received from the portable terminal 7, the process proceeds to S16. In S16, the information in the storage device 5A of the management device 5 is updated. That is, in S16, the "confirmation icon display" of the fuel dispensers ₂₁ to ₂₈ selected by the mobile terminal 7 is updated to "confirmation icon present". For example, when a selection signal for No. 1 refueling machine ₂₁ is received from the mobile terminal 7, as _shown in FIG. do. Since the information of the "confirmation icon display" is updated by this, the "update" of the fueling machine ₂₁ of "01" is set to "yes". Further, for example, when the selection signal is received from the portable terminal 7 of "A" possessed by the staff member "A", as shown in FIG. to 'detailed'. After updating the information in the storage device 5A of the management device 5 in S16, the process returns.

On the other hand, if it is determined that the selection signal has not been received from the mobile terminal 7, that is, if it is determined to be "NO" in S15, the process proceeds to S17. In S17, it is determined whether a permission signal for permitting refueling has been received from the portable terminal 7, or whether the "permit" button 8H on the main monitor 5B of the management device 5 has been pressed. If "YES" in S17, that is, if it is determined that the permission signal has been received from the mobile terminal 7 or the "permit" button 8H on the main monitor 5B of the management device 5 has been pressed, the process proceeds to S18. In S18, a refueling permission signal is transmitted to the refueling machines 2 ₁ to 2 ₈ permitted to refuel. In S19 following S18, the information in the storage device 5A of the management device 5 is updated.

That is, in S19, the "state" of the fuel dispensers 2 ₁ to 2 ₈ permitted to refuel is updated to "refueling", and the "nozzle icon display" is updated to "no nozzle icon". In this case, although not shown, in order to display the fueling icon 13 instead of the nozzle icon 12, the "fueling icon display" is updated to "fueling icon present".

The mobile terminal 7 updates the stored information stored in the storage device 7A of the mobile terminal 7 based on the display screen information signal from the management device 5, that is, the information to be displayed on the display screen of the monitor 8. , the latest information is displayed on the display screen of the monitor 8 . After updating the display screen of the monitor 8 to the latest information in S52, the process proceeds to RETURN. That is, the process returns to START via RETURN, and repeats the processes after S51. On the other hand, if "NO" in S51, that is, if it is determined that the display screen information signal has not been received from the management device 5, the process proceeds to RETURN without going through S52.

In this manner, the portable terminal 7 transmits the display screen information request signal to the management device 5 in S32 of FIG. 6, thereby updating the display screen of the monitor 8 to the latest information. In S33 following S32 in FIG. 6, it is determined whether or not the selection buttons 8A ₁ to 8A ₈ of the fuel dispensers 2 ₁ to 2 ₈ displayed on the monitor 8 have been pressed. If it is determined "NO" in S33, that is, if it is determined that the selection buttons 8A ₁ to 8A ₈ have not been pressed, the process proceeds to S40. If it is determined "YES" in S33, that is, if it is determined that the selection buttons 8A ₁ to 8A ₈ have been pressed, the process proceeds to S34. In S<b>34 , a selection signal is transmitted to the management device 5 . That is, the mobile terminal 7 transmits signals corresponding to the pressed selection buttons 8A ₁ to 8A ₈ to the management device 5 . In S35 following S34, the display screen of the monitor 8 is switched to the detailed screen. That is, in S35, the detailed screen is displayed on the monitor 8 of the portable terminal 7. FIG.

In subsequent S36, it is determined whether or not the "permit" button 8H (FIG. 3) displayed on the detailed screen of the monitor 8 has been operated (pressed). If it is determined "YES" in S36, that is, if it is determined that the "allow" button 8H has been operated (depressed), the process proceeds to S37. In S37, a permission signal for permitting refueling by the selected refueling machine 2 ₁ to 2 ₈ is transmitted from the mobile terminal 7 to the management device 5 . After transmitting the permission signal from the portable terminal 7 to the management device 5 in S37, the process proceeds to S39.

On the other hand, if it is determined that the "permit" button 8H is not operated (pressed) "NO" in S36, the process proceeds to S38. In S38, it is determined whether or not the "return" button 8J (FIG. 3) displayed on the detailed screen of the monitor 8 has been operated (pressed). If it is determined that the "return" button 8J is not operated (depressed) in S38, the process returns to S36, and the processes after S36 are repeated. On the other hand, if it is determined "YES" in S38, that is, if it is determined that the "return" button 8J has been operated (depressed), the process proceeds to S39. At S39, the display screen of the monitor 8 is switched to the list screen. That is, in S39, the list screen is displayed on the monitor 8 of the mobile terminal 7. FIG.

After the list screen is displayed on the monitor 8 in S39, the process proceeds to S40. Moreover, when it determines with "NO" by S33, it progresses to S40. In S40, it is determined whether or not to end the screen display. For example, in S40, if the clerk does not perform an operation for a predetermined time, or if the clerk turns off the mobile terminal 7, it is determined that the screen display should end. If "YES" in S40, that is, if it is determined to end the screen display, the process ends. That is, the process returns to the start via the end, and repeats the processes after S31. On the other hand, if it is determined not to end the screen display, the process returns to before S32, and the processes after S32 are repeated.
