Abstract

<P>PROBLEM TO BE SOLVED: To provide a fuel supply system which displays the amount of change when a customer fills up a fuel tank in payment in advance. <P>SOLUTION: According to the fuel supply system, a fueling screen 94 appears on the display of a touch panel 49 during fuel supply. The fueling screen 94 has a change amount display area 94a for displaying an updated change amount during fueling, a message display area 94b for displaying a message from a gas station, a fuel charge display area 94c for displaying an updated charge corresponding to a fuel amount, and a fuel amount display area 94d for displaying an updated fuel amount. The change amount display area 94a indicates that the fuel supply is in progress, and updates a figure to be displayed to display a change amount that is reduced in response to an increase in a total flow rate of the fuel measured by a flowmeter 72. Thus a customer can confirm a change amount given by subtracting a charge (tax included) from a payment in advance at a glance. Accordingly, the customer can adjust fuel supply from a fuel supply nozzle 60 to make sure that no small bills are included in a change when performing additional fuel supply. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a fuel supply system, and more particularly to a fuel supply system configured to supply fuel to a fuel tank (supplied body) of a vehicle using a cash advance payment type fuel supply machine.

  Here, a fuel supply system for supplying an oil liquid such as gasoline or light oil to a fuel tank of a vehicle will be described as an example.

  At a liquid supply station or the like where a self-service fuel supply machine is installed, the customer (driver) himself sets the liquid supply mode, performs the liquid supply work, and pays the liquid charge. For this reason, the customer (driver) specifies a liquidation fee settlement method (cash payment or credit card payment) and then a setting device having switches such as the type of oil to be supplied and the amount of liquid supplied before supplying the liquid. After performing a setting operation for inputting a predetermined oil type, a liquid supply amount or a liquid supply amount, the liquid supply operation is performed.

In addition, in the case of the so-called island settlement method, in which a setting device for setting the amount of liquid to be supplied or the amount of money to be supplied and an automatic payment machine for depositing banknotes are provided in a cash advance payment self-service fuel supply device It is possible to settle the liquid supply fee at the place. This automatic payment machine is provided with a banknote insertion part and a banknote storage part, and has a banknote discrimination part which discriminates the kind of inserted banknote, and a display part which displays the inserted banknote amount (payment amount).
Then, in the island settlement type fuel supply system, when the liquid is supplied in the full tank supply mode, the customer (driver) predicts the supply amount in advance before supplying the liquid, and inserts it into the bill insertion portion of the automatic payment machine. Insert extra banknotes. Then, after the deposited amount is read by the bill reader and the deposited amount is displayed on the display unit, a desired oil type (regular, high-octane, light oil, etc.) is input to enable the fuel supply machine to supply liquid become.

  When the liquid supply is started, the integrated flow rate measured by the flow meter is displayed on the display unit as the liquid supply amount, and the liquid supply amount obtained by multiplying the current liquid supply amount by the unit price of the fuel (yen / L) Is displayed on the display (see, for example, Patent Document 1).

  After the liquid supply is completed, the change amount is calculated by subtracting the total amount of the supply amount and the consumption tax corresponding to the supply amount from the deposit amount, and the change amount is paid to the customer. At that time, the customer receives a 1-yen coin change when the change is in one digit, so the nozzle operation is to adjust the liquid supply amount so that the smallest change is not possible. May do.

Therefore, when the liquid supply nozzle operates the automatic valve closing mechanism by the liquid level rise in the fuel tank and closes the main valve, the customer calculates the change amount from the liquid supply amount displayed on the display, and is small. Adjust the additional liquid supply amount so that the change of the amount does not come out. As a result, for example, when the deposit amount is 5,000 yen, the nozzle lever of the liquid supply nozzle is opened little by little so that the fraction does not appear in one digit (for example, the change is 300 yen or 150 yen). It is operating.
Japanese Patent Laid-Open No. 5-77895

However, since the amount of liquid supply and the amount of liquid supply are conventionally displayed on the display of the fuel supply machine, the customer himself / herself calculates the amount of change, which not only complicates the operation of the customer, but also makes a calculation error. Even if the nozzle lever of the liquid supply nozzle is opened little by little so that the fraction does not appear at a corner or a single digit, the fraction will appear at a single digit, resulting in a 1-yen change. There is a case.
Therefore, an object of the present invention is to provide a fuel supply system that solves the above problems.

The present invention provides a depositing machine in which money is deposited prior to the supply of fuel to the supply target,
A fuel supply machine that supplies fuel to the supplied body on condition that money is deposited in the depositing machine;
A measuring means for measuring the fuel supply amount;
Fuel supply amount calculation means for calculating a fuel supply amount corresponding to the fuel supply amount based on the measurement value by the measurement means;
A change amount calculating means for calculating a change amount by subtracting a fuel supply amount corresponding to a fuel supply amount from the deposit amount;
Display means for displaying the change amount calculated by the change amount calculation means;
It is provided with.

  According to the present invention, since the change amount calculated by the change amount calculation means is displayed and notified, it is troublesome to calculate the change amount by subtracting the supply amount from the deposit amount while performing the supply operation as in the past. It is possible to adjust the amount of liquid supply relatively easily so that no change is included in the change.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The memory 80 also has a control program I (fuel supply amount calculation means) for calculating a fuel supply amount corresponding to the fuel supply amount based on a measured value by a flow meter 72 described later, and corresponds to the fuel supply amount from the deposit amount. A control program II (change amount calculation means) for calculating the change amount by subtracting the amount of fuel supply to be performed and a control program III (display means) for displaying the calculated change amount on the touch panel 49 are stored.

  Here, a display example of the setting operation screen displayed on the touch panel 49 of the setting device 26 will be described with reference to FIGS. 4 to 10.

  Procedure A: When the customer (driver) stands in front of the setting device 26, the human detection sensor 50 is turned on. As shown in FIG. 4, a payment method input screen 84 is displayed on the screen of the touch panel 49. Is done.

  The payment method input screen 84 has a message display area 84a and a setting operation display area 84b. In the message display area 84a, for example, guidance for an operation procedure such as “Please select a payment method” is displayed. The setting operation display area 84b displays a message such as “Irasement”, a cash selection button 84d for selecting a cash payment method, and a credit card selection for selecting a credit card payment method. A button 84e is displayed.

  The customer (driver) selects the payment method by touching the display area of the cash selection button 84d or the credit card selection button 84e displayed on the touch panel 49. As described above, when a payment method is selected, the process proceeds to the next procedure B.

  Procedure B: For example, when a cash payment method is selected in Procedure A, a bill deposit screen 86 is displayed on the screen of the touch panel 49 as shown in FIG.

  The banknote deposit screen 86 has a message display area 86a and a setting operation display area 86b. In the message display area 86a, for example, an operation procedure guidance such as “Please insert a bill from the right bill insertion slot” is displayed.

  Further, in the setting operation display area 86b, a deposit amount display field 86c for displaying the amount of the bill inserted into the bill insertion section 52, and “OK” if the amount is displayed are displayed in the deposit amount display field 86c. An operation procedure guidance 86d such as “Please”, a cancel button 86e, and an enter button 86f are displayed.

  Therefore, the customer (driver) inserts the banknote into the banknote insertion unit 52, confirms that the amount displayed in the deposit amount display field 86c matches the deposit amount, and presses the decision button 86f. If the amount displayed in the deposit amount display field 86c does not match the deposit amount, the cancel button 86e is pressed.

  As described above, when the determination button 86f or the cancel button 86e is pressed after the bill is inserted, the process proceeds to the next procedure C.

  Procedure C: For example, when the enter button 86f is pressed in Procedure B, a liquid type selection screen 88 is displayed on the screen of the touch panel 49 as shown in FIG.

  The liquid type selection screen 88 has a message display area 88a and a setting operation display area 88b. In the message display area 88a, for example, guidance for an operation procedure such as “Please select a liquid type” is displayed.

  In the setting operation display area 88b, a regular selection button 88c, a high-octane selection button 88d, a light oil selection button 88e, a cancel button 88f, and a button 86g for returning to the deposit screen are displayed.

  Therefore, the customer (driver) presses the liquid type selection button (for example, the regular selection button 88c) of the liquid type corresponding to the engine specification of the vehicle. If the liquid type selection operation is wrong, the cancel button 88f is pressed. When the deposit amount is changed, the button 86g for returning to the deposit screen is pressed.

  As described above, when any one of the liquid type selection buttons 88c, high-octane selection button 88d, and light oil selection button 88e is pressed, the process proceeds to the next procedure D.

  Procedure D: When the liquid type selection operation is performed in the procedure C, a setting confirmation screen 90 is displayed on the screen of the touch panel 49 as shown in FIG.

  The setting confirmation screen 90 has a message display area 90a and a setting operation display area 90b. In the message display area 90a, for example, a guidance for an operation procedure such as “please check the setting contents” is displayed.

  In the setting operation display area 90b, the payment method, liquid type, deposit amount, unit price, liquid supply method (preset liquid supply mode or full tank liquid supply mode) set in steps 1 to 3 and preset liquid supply are displayed. In the case, the preset data amount 90c, the amount designation button 90d, the amount designation button 90e, the confirmation button (pre-operation completion detection means) 90f, the cancel button 90g, and the liquid type screen are displayed. A return button 90h is displayed.

  When setting the liquid supply amount, the amount designation button 90d is pressed. In this case, it is possible to preset an arbitrary liquid supply amount within the range of the deposit amount. In addition, when the amount of liquid supply is set, the amount designation button 90e is pressed. In this case, it is possible to preset an arbitrary liquid supply amount with the deposit amount as a maximum value.

  The confirmation button 90f displays “Confirm” when supplying liquid in the preset liquid supply mode, and displays “Full tank” when supplying liquid in the full tank liquid supply mode. Therefore, the confirmation button 90f is displayed as “full” when the customer (driver) does not press the amount designation button 90d or the amount designation button 90e, and the customer (driver) displays the amount designation button 90d or the amount. When the designation button 90e is pressed, “Confirm” is displayed.

  Therefore, it can be easily understood that when the liquid is supplied in the full tank liquid supply mode, the confirmation button 90f may be pressed after selecting the liquid type. Further, instead of the confirmation button 90f, other detection means can be used as the preliminary operation completion detection means. For example, when the nozzle switch 74 is turned off, it can be determined that the preliminary operation has been completed. Alternatively, it is possible to determine that the preliminary operation is completed by the flow rate pulse output from the flow meter 72.

  Thus, when the setting operation of the preset liquid supply mode or the full tank liquid supply mode is completed, the process proceeds to the next procedure E.

  Step E: When a setting operation is performed in the above step D, a setting completion screen 92 is displayed on the screen of the touch panel 49 as shown in FIG.

  The setting completion screen 92 has a message display area 92a and a setting completion display area 92b. In the message display area 92a, for example, a guidance for an operation procedure such as “please insert the nozzle into the liquid supply port and pull the lever” is displayed.

  The setting completion screen 92 also includes a setting data display unit 92c for displaying the above setting data (payment method, liquid type, deposit amount, liquid supply method, preset amount in preset liquid supply mode, preset amount), and cancel. A button 92d is displayed.

  Therefore, the customer (driver) confirms the setting data displayed on the setting data display unit 92c, and then removes the liquid supply nozzle 60 from the nozzle hook 62 and inserts it into the liquid supply port of the vehicle (not shown). Then, when the nozzle lever of the liquid supply nozzle 60 is opened, liquid supply is started.

  Thus, when the liquid supply to the vehicle is started, the process proceeds to the next procedure F.

  Procedure F: When a liquid supply start operation is performed in the above procedure E, a liquid supply screen 94 is displayed on the screen of the touch panel 49 as shown in FIG.

  The in-liquid supply screen 94 updates and displays a change amount display area 94a for displaying the change amount during supply, a message display area 94b for displaying a message from the supply station, and an amount corresponding to the supply amount. A liquid supply amount display area 94c and a liquid supply amount display area 94d for updating and displaying the liquid supply amount are provided.

  Further, the change amount display area 94a displays that the liquid is being supplied, and the numerical value is updated so that the change amount subtracted with the increase in the integrated flow rate measured by the flow meter 72 is displayed. Thereby, the customer can confirm at a glance the change amount obtained by subtracting the liquid supply amount (including tax) from the deposit amount.

  Procedure G: When the liquid supply is completed in the above procedure E, a liquid supply end screen 96 is displayed on the screen of the touch panel 49 as shown in FIG.

  The liquid supply screen 96 has a message display area 96a and a liquid supply result display area 96b for displaying the liquid supply result. In the message display area 96a, for example, a message such as “end of liquid supply” is displayed to notify the customer (driver) that the liquid supply has ended.

  In addition, in the liquid supply result display area 96b, for example, a message such as “Thank you” is displayed, and the numerical values of the liquid supply amount, the tax-included liquid supply amount, the consumption tax amount, the payment method, the liquid type, the deposit amount, Setting data such as the liquid supply method is displayed.

  Thus, the customer (driver) confirms the liquid supply amount and the tax-included liquid supply amount by the current liquid supply operation from the liquid supply end screen 96 displayed on the touch panel 49.

  The liquid supply end screen 96 is displayed for a predetermined time after the liquid supply nozzle 60 is returned to the nozzle hook 62. Thereafter, a setting start screen 84 shown in FIG. 4 is displayed on the screen of the touch panel 49.

  In the present embodiment, the case where the screens of the procedures A to G are displayed in order has been described. However, for example, the setting completion screen 92 of the procedure E (see FIG. 8) is omitted, and the procedure D is changed to the procedure F. You may make it move.

  Here, a control process executed by the control circuit 66 of the fuel supplier 16 will be described with reference to FIGS. 11 and 12.

  As shown in FIG. 11, the control circuit 66 checks whether or not the human detection sensor 50 is on in step S <b> 11 (hereinafter, “step” is omitted). When the human detection sensor 50 is turned on, it is determined that the customer is in front of the setting device 26, and the process proceeds to S12, where a payment method input screen 84 (see FIG. 4) is displayed on the touch panel 49 of the setting device 26.

  In the next S13, it is checked whether or not the credit card selection button 84e has been pressed. If the credit card selection button 84e is pressed in S13, the process proceeds to S14 to check whether the cash selection button 84d is pressed. If the cash selection button 84d is not pressed in S14, the process returns to S11.

  In S13, when the credit card selection button 84e is pressed, the process proceeds to S15, and it is checked whether or not the card inserted into the card insertion unit 54 is normal. In S15, if the card inserted in the card insertion unit 54 has expired or is not a contract, the process proceeds to S16, returns the card, and returns to S11.

  In S15, if the card inserted into the card insertion unit 54 is usable, the process proceeds to S17, and a normal liquid supply process is performed. When a credit card is used, there is no need to display the change amount, so the description of the subsequent processing is omitted.

  In S14, when the cash selection button 84d is pressed, the process proceeds to S18, and a bill deposit screen 86 (see FIG. 5) is displayed on the touch panel 49 to instruct bill insertion. In next S <b> 19, it is checked whether or not a bill has been inserted into the bill insertion portion 52.

  In S19, when a banknote is inserted into the banknote insertion part 52, the process proceeds to S20, and the type of the banknote inserted into the banknote insertion part 52 (thousand-yen bill, 2,000-yen bill, 5,000-yen bill, 10,000-yen bill) ) Is discriminated by the bill discriminating section 76, and the deposit amount as the discrimination result is displayed (see FIG. 5). Subsequently, in S21, it is checked whether or not the determination button 86f on the banknote deposit screen 86 has been pressed. In S21, when the determination button 86f on the banknote deposit screen 86 is not pressed, the process returns to S19, and the processes after S19 are executed again.

  In S21, when the determination button 86f on the banknote deposit screen 86 is pressed, the process proceeds to S22, and the liquid type selection screen 88 (see FIG. 6) is displayed on the touch panel 49.

  In the next S23, it is checked whether any of the regular selection button 88c, the high-octane selection button 88d, or the light oil selection button 88e displayed on the liquid type selection screen 88 has been pressed. In S23, when any of the regular selection button 88c, the high-octane selection button 88d, and the light oil selection button 88e is pressed to select a liquid type, the process proceeds to S24, and a setting confirmation screen 90 (see FIG. 7) is displayed on the touch panel 49. Confirm the settings.

  At this time, the confirmation button 90f of the setting confirmation screen 90 is displayed as “Confirm” in the preset liquid supply mode, and “Full tank” in the full tank liquid supply mode. As a result, the customer (driver) can easily understand that it is only necessary to press the confirmation button 90f after selecting the liquid type when supplying the liquid in the full tank supply mode. This also eliminates the time required for the liquid supply setting operation.

  Subsequently, as shown in FIG. 12, in S25, it is checked whether or not the confirmation button (full tank) 90f has been pressed. In S25, when the confirmation button (full tank) 90f is not pressed, it is determined that the preset liquid supply mode is selected without selecting the full liquid supply mode, and the process proceeds to S26. It is checked whether or not the amount designation button 90d has been pressed.

  If the amount designation button 90d on the setting confirmation screen 90 is not pressed in S26, the process proceeds to S27 to check whether or not the amount designation button 90e on the setting confirmation screen 90 is pressed. If the amount designation button 90e on the setting confirmation screen 90 is not pressed in S27, the process returns to S25 and repeats the processes of S25 to S27.

  In S25, when the confirmation button (full tank) 90f is pressed, it is determined that the full tank liquid supply mode is selected, and the process proceeds to S28, and a setting completion screen 92 (see FIG. 8) is displayed on the touch panel 49. Display and instruct the start of liquid supply operation.

  In the next S29, it is checked whether the nozzle switch 74 provided on the nozzle hook 62 is off. When the nozzle switch 74 is OFF in S29, it is determined that the liquid supply nozzle 60 is inserted into the liquid supply port of the vehicle (not shown), and the process proceeds to S30, where the liquid supply pump 70 is activated. Then, it progresses to S31 and integrates the flow rate pulse output from the flowmeter 72, and calculates | requires the liquid supply amount.

  In next S32, a liquid supply screen 94 (see FIG. 9) is displayed on the screen of the touch panel 49, and liquid supply information during liquid supply (liquid supply amount, tax-inclusive amount, unit price, etc.) is displayed. Then, the process proceeds to S33, in which the change amount corresponding to the supply amount is subtracted from the deposit amount, and the change amount corresponding to the supply amount is displayed in the change amount display area 94a of the supply-in-progress screen 94 for notification. In this way, the change amount is displayed in the change amount display area 94a of the liquid supply screen 94. Therefore, when the additional supply described later is performed, the change supply nozzle 60 can be easily supplied so that no change is included in the change. It becomes possible to adjust the amount of liquid.

  In next S <b> 34, it is checked whether or not the actual liquid supply amount matches the deposit amount of the bill inserted in the bill insertion unit 52. In S34, when the actual liquid supply amount does not coincide with the deposit amount of the bill inserted into the bill insertion portion 52, the process proceeds to S35, and it is checked whether the nozzle switch 74 provided in the nozzle hook 62 is off. In S35, when the nozzle switch 74 is OFF, it is determined that the liquid supply nozzle 60 is inserted into the liquid supply port of the vehicle (not shown), and the process returns to S31.

  In S35, when the nozzle switch 74 is on, it is determined that the liquid supply nozzle 60 has been returned to the nozzle hook 62 and liquid supply has been completed, and the flow proceeds to S36. In S34, when the actual liquid supply amount coincides with the deposit amount of the banknote inserted into the banknote insertion portion 52, the upper limit is reached so that the process proceeds to S36 and the operation of the liquid supply pump 70 is stopped. Let

  In the next S37, it is confirmed whether or not there is a change obtained by subtracting the liquid supply amount (including tax) from the advance payment amount. If there is no change in S37, the process proceeds to S38, and a liquid supply end screen 96 (see FIG. 10) is displayed on the touch panel 49. In S39, it is confirmed whether or not a predetermined time has elapsed. In S39, when a predetermined time has elapsed, the process proceeds to S40, and the display screen of the touch panel 49 is deleted. This completes the liquid supply process for the full tank liquid supply.

  If there is change in S37, the process proceeds to S41, and the change amount (including consumption tax) is subtracted from the advance payment amount from the change payout unit 57 (see FIG. 2). The calculated change is paid out.

  If the preset liquid supply is set, that is, if the amount designation button 90d on the setting confirmation screen 90 is pressed in S26, the process proceeds to S42, and the amount designation selection screen (not shown) is displayed on the touch panel 49. On the screen.

  In the next S43, it is checked whether the liquid supply amount has been input and the confirmation button 90f has been pressed. In S43, when the confirmation button 90f is pressed, the process proceeds to S44, and the setting confirmation screen 90 is displayed on the screen of the touch panel 49 to confirm the setting contents.

  In the next S45, it is checked whether or not the confirmation button 90f has been pressed to confirm the setting contents such as the liquid supply amount. When the confirmation button 90f is pressed in S45, the process proceeds to S46, and it is checked whether the nozzle switch 74 provided on the nozzle hook 62 is off. When the nozzle switch 74 is off in S46, it is determined that the liquid supply nozzle 60 is inserted into the liquid supply port of the vehicle (not shown), and the process proceeds to S47, where the liquid supply pump 70 is activated. Subsequently, the process proceeds to S48, in which the flow rate pulses output from the flow meter 72 are integrated to determine the liquid supply amount.

  In the next S49, a liquid supply screen 94 (see FIG. 9) is displayed on the screen of the touch panel 49, and liquid supply information during liquid supply (liquid supply amount, tax-included amount, unit price, etc.) is displayed. In step S50, it is checked whether the liquid supply amount or the liquid supply amount measured by the flow meter 72 has reached a preset value. In S50, when the liquid supply amount or the liquid supply amount does not reach the preset preset value, the process returns to S48 and the preset liquid supply is continued.

  In S50, when the liquid supply amount or the liquid supply amount reaches a preset preset value, the process proceeds to S51 and the liquid supply pump 70 is stopped.
