It is a flowchart for demonstrating the control process which the control circuit of a fuel supply apparatus performs following the control process of FIG.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a schematic configuration of a fuel supply system to which an embodiment of a fuel supply apparatus according to the present invention is applied. As shown in FIG. 1, the fuel supply system 10 includes a self-service fuel supply device 16 installed in a fuel supply area 12 and a management computer 20 installed in an office 18. The management computer 20 manages each device installed in the fuel supply station, and when the fuel supply request signal is output from the fuel supply device 16, the staff member is in a normal state around the fuel supply device 16. The fuel supply permission signal is transmitted to the fuel supply device 16 by confirming the above and operating the permission button.

  The management computer 20 and the control circuit mounted on the fuel supply device 16 are connected via the SS-LAN 22 so as to be capable of bidirectional communication.

  The fuel supply device 16 includes a weighing machine 24, a setting device 26, and a display device 27. The weighing machine 24 is provided with a setting device 26 on the front and back of the weighing machine main body 28, and each oil type (in this embodiment, for example, three types of oils such as light oil, high-octane gasoline, and regular gasoline). ) A nozzle storage portion 32 for holding each nozzle 30 is provided.

  In addition, a hose 34 to which fuel is supplied is connected to each nozzle 30, and the hose 34 is suspended from a hose support portion 35 provided at the upper part of the weighing machine main body 28. Each hose 34 communicates with a fuel supply path (not shown) disposed inside the measuring machine main body 28, and each fuel supply path is provided with devices such as a flow meter, an electromagnetic valve, and a pump.

  The nozzle 30 is provided with a wireless receiving device (receiving means) 90. The receiving device 90 functions as a detecting means for detecting the position of the customer (operator) X who performs the nozzle operation, and is configured to be able to receive a radio wave having a preset specific frequency.

  The customer (operator) X possesses a transmission device (transmission means) 100 that wirelessly transmits information for specifying the customer when operating the fuel supply device 16. The transmission device 100 is a transmission unit composed of, for example, a card-type transmitter, and is arranged for each weighing machine 24. A transmission device storage unit 110 that stores the transmission device 100 when the input operation is completed is provided on the front surface of the weighing machine 24.

  Therefore, when the setter 26 is operated by the customer X and an oil type, quantity, and the like are input, voice guidance is performed so that the transmission device 100 is taken out from the transmission device storage unit 110 of the weighing machine 24. And the customer X can make the fuel supply apparatus 16 recognize the position with respect to the nozzle 30 by the signal transmitted from the transmission apparatus 100 by having the transmission apparatus 100 concerned.

  In the receiving device 90 and the transmitting device 100, wireless communication is performed using a communication method called narrow-range communication or DSRC (Dedicated Short Range Communication), so that it does not interfere with other weighing machines.

  In addition, the transmission / reception possible range by the reception device 90 and the transmission device 100 can be set to an arbitrary distance in the range of 2 m to 5 m, for example, by adjusting the transmission output of the transmission device 100. Therefore, when the customer (operator) X moves to a position where the separation distance from the nozzle 30 exceeds the transmission / reception range, the reception device 90 cannot receive the signal transmitted from the transmission device 100. Therefore, when the receiving device 90 cannot receive the signal transmitted from the transmitting device 100, the control circuit of the fuel supply device 16 is separated from the customer (operator) X by a predetermined set value (transmission / receivable range) or more. It is possible to determine that the position has been moved.

  Further, the memory of the control circuit of the fuel supply device 16 stores a control program (control) for stopping the fuel supply when the customer (operator) X is separated from the nozzle 30 by a preset value (transmission / reception range) or more. Means) is stored. Therefore, in the fuel supply device 16, when the customer (operator) X opens the nozzle 30 to start fuel supply and then moves away from the nozzle 30 by a preset value (transmittable / receivable range) or more. The fuel supply is stopped by stopping the pump of the fuel supply path with which the nozzle 30 is communicated, or by closing the solenoid valve of the fuel supply path.

  Further, in the memory of the control circuit of the fuel supply device 16, for example, when the customer (operator) X performs the valve closing operation of the lever 30d of the nozzle 30 during the fuel supply, or the automatic refueling stop mechanism of the nozzle 30 is activated. Thus, when the fuel supply from the nozzle 30 is stopped, the customer (operator) X moves away from the nozzle 30 by a predetermined distance or more (the customer (operator) X moves out of the transmission / reception range). A control program for stopping the fuel supply by stopping the pump of the fuel supply path with which the nozzle 30 is communicated or by closing the electromagnetic valve of the fuel supply path.

  Further, in the memory of the control circuit of the fuel supply device 16, when the customer (operator) X returns from the nozzle 30 within a preset set value (transmission / reception range) after stopping the fuel supply, A control program (control means) for restarting the fuel supply by restarting the pump of the fuel supply path with which the nozzle 30 is communicated or opening the solenoid valve of the fuel supply path is stored.

  And when the fuel supply with respect to the said vehicle is complete | finished, a payment process (payment of change or return of a prepaid card) is performed by returning the transmission apparatus 100 to the transmission apparatus accommodating part 110 of the said measuring machine 24. FIG. A barcode seal 102 on which a barcode for identifying the transmission device 100 attached to the weighing machine 24 is printed is attached to the transmission device 100.

  Further, a transmitter detector 112 is provided on the lower surface of the transmitter storage unit 110 as detection means for detecting that the transmitter 100 is stored. The transmitter detection unit 112 includes a barcode reader. When the barcode printed on the barcode seal 102 is optically read, it is recognized that the transmission device 100 is stored in the transmission device storage unit 110.

  Therefore, when the transmitter 100 is stored in the transmitter storage unit 110 with the barcode seal 102 facing downward, the control circuit of the fuel supply device 16 reads the barcode seal 102 from the transmitter detector 112 and transmits the transmitter. It can be determined that 100 has been returned.

  In this embodiment, the self-service fuel supply device 16 will be described. Similarly, in the case of a full-service fuel supply device in which an attendant performs a nozzle operation, the attendant possesses the transmitter 100. When the clerk is away from the nozzle 30 by a preset set value (transmittable / receivable range) or more, the fuel supply is stopped, and the clerk is returned from the nozzle 30 within the preset set value (transmit / receiveable range). The above control program for resuming fuel supply is executed.

  Further, in the case of a full-service fuel supply apparatus, since the attendant always has the transmission apparatus 100, the transmission apparatus storage section 110 becomes unnecessary.

  FIG. 2 is a side view of the nozzle 30. As shown in FIG. 2, the nozzle 30 includes a discharge pipe 30a inserted into a fuel supply port on the vehicle side, a nozzle body 30b having an automatic valve closing mechanism that automatically closes by detecting the liquid level, and a nozzle body 30b.

A battery 106 is housed. Further, since the transmitting device 100 is packaged by the case 101 that forms one card, the external appearance is a fuel supply ID card that is used only by the fuel supply device 16.

  The control unit 103 causes the wireless transmitter 104 to transmit identification data stored in the memory 105 at a preset time interval. The transmitted identification data includes unique data corresponding to the fuel supply device 16 and is programmed not to be confused with the identification data of other fuel supply devices 16.

  FIG. 4 is a system diagram schematically illustrating the schematic configuration of the transmission device 100, the reception device 90, and the weighing machine 24. As shown in FIG. 4, when the fuel supply by the nozzle 30 is started, the control circuit 36 mounted on the fuel supply device 16 integrates the flow rate pulse output from the flow meter 42, and the integrated fuel A numerical value of the supply amount is displayed on the display 27.

  The receiving device 90 mounted on the nozzle 30 includes a control unit 94 formed of a microcomputer, a wireless receiver 96, and a wireless antenna 98.

  In addition, the receiving device 90 determines whether or not the signal transmitted from the transmitting device 100 is received by the wireless receiver 96 when the fuel is being supplied. It is possible to determine that the distance is 30 or more from the predetermined distance.

  FIG. 5 is a plan view of the fuel supply device and the liquid supply point as seen from above. As shown in FIG. 5, in the fuel supply device 16, when the nozzle 30 is opened while the nozzle 30 is connected to the fuel supply port of the vehicle C, the receiving device 90 mounted on the nozzle 30 Fuel supply is continued on condition that the operator X is in the transmission / reception possible range P1. In addition, when the fuel supply device 16 is a full service system, an attendant becomes an operator, so that the transmission / reception possible range P2 of the reception device 90 is set to P1 of the self service system so that operations such as window cleaning can be performed during fuel supply. (P1 <P2). For example, the transmission / reception possible range P1 is set to a range with a radius of 2 m, and the transmission / reception possible range P2 is set to a range with a radius of 5 m.

  Thus, since the transmission / reception range can be changed as appropriate, it can be set to a range according to the request of the customer or the staff so that the nozzle operation is not hindered or the service to the customer is not deteriorated. Is possible.

  FIG. 6 is a block diagram showing the configuration of each device of the fuel supply device 16. As shown in FIG. 6, the control circuit 36 of the fuel supply device 16 is composed of a microcomputer, and a setter 26, an indicator 27, a power supply circuit 37, and a two-stage valve closing provided in each fuel supply path. Type solenoid valve 38, pump 40, flow meter 42, memory 44, human detection sensor 46, intercom 48, nozzle switch 50 provided in the nozzle storage section 32, static electricity removal detection switch 54, slip issuing machine 58 for issuing slips, The speaker 60 that performs voice guidance, the wireless receiver 96, and the transmitter detector 112 are connected.

  The power supply circuit 37 is connected via a power supply cable (not shown) so as to supply power not only to the control circuit 36 but also to all other devices constituting the fuel supply device 16.

  Then, the control circuit 36 lights or blinks a lamp corresponding to an operation to be performed next in accordance with an input operation by the operator, and causes the speaker 60 to utter voice guidance.

  FIG. 7 is a flowchart for explaining the main control process executed by the control circuit 36 of the weighing machine 24. In FIG. 7, when a detection signal (ON) is output from the human detection sensor 46 in S <b> 11, the control circuit 36 proceeds to S <b> 12 and starts guidance of an operation method by sound from the speaker 60. At this time, the operator completes the setting of the oil type and quantity to be supplied with fuel, and performs voice guidance so that the transmitter 100 is held before the nozzle operation is performed.

  In the next S13, the oil to be supplied by the operator by operating the fuel selection buttons 64 to 66, the full tank button 68, the supply amount setting buttons 70 to 73, and the money amount setting buttons 76 to 79 of the setting device 26. The seed and quantity are stored in the memory 44 as setting data. Then, it progresses to S14 and it is checked whether the setting of the oil kind and quantity which should supply fuel is completed. In S14, when the input setting data is corrected, the process returns to S13, and the oil type and quantity to be supplied with fuel are re-input. In S14, when the setting of the oil type and quantity to be supplied with fuel is completed, the process proceeds to S15 to check whether or not the transmission device 100 is stored in the transmission device storage unit 110.

  In S <b> 15, when the barcode printed on the barcode seal 102 of the transmission device 100 cannot be read by the transmitter detection unit 112 provided in the transmission device storage unit 110, the transmission device 100 is stored in the transmission device storage unit 110. In S16, the management computer 20 is informed that the transmission device 100 is not accommodated. Thereby, the operator of the management computer 20 carries the transmitter 100 that can be used in the fuel supply device 16 to the fuel supply device 16 to enable fuel supply.

  In S <b> 15, when the barcode printed on the barcode sticker 102 of the transmission device 100 is read by the transmitter detection unit 112 provided in the transmission device storage unit 110, the transmission device 100 transmits the transmission device storage unit 110. The process proceeds to S17. In S17, the permission request signal is output to the management computer 20. The operator of the management computer 20 confirms the image by the monitoring camera of the fuel supply device 16 and turns on the permission button. As a result, the management computer 20 outputs a permission signal to the fuel supply apparatus 16 that has output the permission request signal.

  In step S18, it is checked whether a fuel supply permission signal is input from the upper management computer 20. In S18, when a fuel supply permission signal is input from the management computer 20, the process proceeds to S19, and the previous fuel supply amount displayed on the display unit 27 is reset to zero.

  Subsequently, in S20, it is checked whether or not the receiving device 90 of the nozzle 30 can receive the signal transmitted from the transmitting device 100. In S20, when the receiving device 90 of the nozzle 30 can receive the signal transmitted from the transmitting device 100, the process proceeds to S21, where the pump 40 in the fuel supply path is activated and the electromagnetic valve 38 is opened. The operator takes out the transmission device 100 from the transmission device storage portion 110 and holds it before picking up the nozzle 30 from the nozzle storage portion 32. Since the transmission device 100 is an ID card for fuel supply, it is held by the operator until the fuel supply is completed. When the fuel supply is completed, the transmission device 100 is returned to the transmission device storage unit 110.

  When the nozzle lever 30d of the nozzle 30 inserted in the fuel supply port of the vehicle C is operated in the valve opening direction, the fuel fed by the pump 40 is supplied to the fuel tank of the vehicle C. In S 22, the supply amount is calculated by integrating the flow rate pulses output from the flow meter 42, and the supply amount is displayed on the display unit 27.

  In next S23, it is checked whether or not the receiving device 90 of the nozzle 30 can receive the signal transmitted from the transmitting device 100 during the fuel supply. In S23, when the receiving device 90 of the nozzle 30 cannot receive the signal transmitted from the transmitting device 100, the operator who owns the transmitting device 100 leaves the nozzle 30 and can transmit and receive the receiving device 90 (see FIG. 5). It moves to the outer side, and it progresses to S24. In S24, 1 is added to the count value of the timer t. Subsequently, in S25, it is checked whether or not the count value of the timer t has reached a preset set time. In S25, when the count value of the timer t has not reached the preset set time, the process proceeds to S27.

  In S23, when the receiving device 90 of the nozzle 30 can receive the signal transmitted from the transmitting device 100, the process proceeds to S26, and the timer t is reset to zero. In the next S27, it is checked whether or not the nozzle switch 50 is on. If the nozzle switch 50 is on, it is determined that the nozzle 30 has been returned to the state of being housed in the nozzle housing portion 32.

  In S27, when the nozzle switch 50 of the nozzle storage section 32 is off, the nozzle 30 is not stored in the nozzle storage section 32, so the process proceeds to S28, and whether or not the flow rate pulse from the flow meter 42 is stopped. Is checked (stop determination means). In S28, when the flow rate pulse is output from the flow meter 42, the fuel supply is continued, so the process returns to S22, and the processes after S22 are repeated.

  If the flow rate pulse from the flow meter 42 is not output in S28, it is determined that the fuel supply from the nozzle to the fuel tank is stopped, and the process proceeds to S29, where the receiving device 90 of the nozzle 30 is transmitted to the transmitting device 100. It is checked whether the signal transmitted from can be received. In S29, when the receiving device 90 of the nozzle 30 can receive the signal transmitted from the transmitting device 100, the fuel supply is continued. Therefore, the process returns to S22, and the processes after S22 are repeated.

  In S25, when the count value of the timer t reaches a preset time, or in S29, when the receiving device 90 of the nozzle 30 cannot receive the signal transmitted from the transmitting device 100, the operator It is determined that the receiver 90 has moved to a position outside the transmission / reception range of the receiving device 90, and the process proceeds to S30 in FIG. 8 where the pump 40 is stopped and the electromagnetic valve 38 is closed. Thereby, since the fuel supply to the nozzle 30 is stopped, the fuel supply to the fuel tank of the vehicle C to which the nozzle 30 is connected is stopped.

  That is, during fuel supply and when fuel supply is temporarily stopped, it can be determined that the operator has moved away from the nozzle 30 and moved outside the transmission / reception range of the receiver 90, and the pump 40 can be stopped. Therefore, while the operator is away from the nozzle 30, another person operates the nozzle lever 30d of the nozzle 30 to supply fuel to a container other than the vehicle C, or the nozzle lever 30d is opened. It is possible to prevent overflow when the fuel is supplied while being locked. Further, according to the present invention, the fuel supply is stopped when the operator leaves the nozzle 30 during fuel supply. Therefore, when the operator is absent during the fuel supply and the nozzle 30 falls out of the fuel supply port, the nozzle 30 is removed. Therefore, fuel can be prevented from being scattered around the vehicle C.

  In S31, the operator is notified by voice from the speaker 60 that the fuel supply is stopped.

  Subsequently, the process proceeds to S32, where it is checked whether or not the nozzle switch 50 is turned on. When the nozzle switch 50 is turned off, the nozzle 30 is not housed in the nozzle housing part 32, so the process proceeds to S33 and fuel is supplied. During this, it is checked whether or not the receiving device 90 of the nozzle 30 can receive the signal transmitted from the transmitting device 100.

  In S32, when the nozzle switch 50 is on, the fuel supply is completed and the nozzle 30 is stored in the nozzle storage portion 32. Therefore, the process proceeds to S36 described later.

  In S33, when the receiving device 90 of the nozzle 30 cannot receive the signal transmitted from the transmitting device 100, the process returns to S30, and the processes after S30 are repeated. In S33, when the receiving device 90 of the nozzle 30 can receive the signal transmitted from the transmitting device 100, the process proceeds to S34, where the operator operates the speaker 60 to start the stopped pump 40. To inform.

  And it returns to said S21 and restarts the pump 40 and restarts fuel supply. Thereby, when the operator returns from the position away from the nozzle 30 to the inside of the transmission / reception possible range of the receiving device 90, the pump 40 is restarted and the fuel supply to the nozzle 30 is automatically restarted.

  In S27, when the nozzle switch 50 is on, it is determined that the fuel supply to the vehicle has been completed and the nozzle 30 has been stored in the nozzle storage portion 32, and the process proceeds to S35 to operate the pump 40. And the solenoid valve 38 is closed. When the fuel supply operation to the vehicle C is completed, the operator returns the transmission device 100 to the transmission device storage unit 110.

  Subsequently, in S <b> 36, it is checked whether or not the transmission device 100 is stored in the transmission device storage unit 110. In S <b> 36, when the barcode printed on the barcode sticker 102 of the transmission device 100 cannot be read by the transmitter detection unit 112 provided in the transmission device storage unit 110, the transmission device 100 is stored in the transmission device storage unit 110. In step S37, the operator notifies the operator through the speaker 60 that the transmitting device 100 is returned to the transmitting device storage unit 110.

  In S <b> 36, when the barcode printed on the barcode sticker 102 of the transmission device 100 is read by the transmitter detection unit 112 provided in the transmission device storage unit 110, the transmission device 100 transmits the transmission device storage unit 110. The process proceeds to S38.

  In S38, the management computer 20 is notified of the fuel supply amount supplied to the vehicle C by the nozzle 30. Subsequently, in S39, the fuel supply amount is settled. In S39, when there is a change for the cash inserted before the fuel supply, a receipt on which the fuel supply amount, the input amount, the fuel supply fee, and the change are printed is issued from the slip issuing machine 58. The customer can receive the change by having the change machine in the office read the receipt on which the change data (for example, a barcode) is written.

  In addition, when a customer inserts a prepaid card, a prepaid card in which the frequency (amount) corresponding to the current fuel supply amount is subtracted from the amount data stored in the prepaid card, and the frequency corresponding to the difference is overwritten as the remaining amount To return. As described above, when the fuel supply is completed, the settlement process is executed on condition that the transmission device 100 is stored (returned) in the transmission device storage unit 110.

  In the above-described embodiment, the fuel supply apparatus configured to supply liquid fuel such as gasoline or light oil to the fuel tank of the vehicle has been described. However, the present invention is not limited to this. For example, LPG (liquefied petroleum gas) or LNG (liquefied liquefaction) Natural gas), CNG (compressed natural gas), and of course, the present invention can also be applied to a gas supply fuel supply device that is filled with a gas such as hydrogen as fuel for a fuel cell.

  Further, in the above-described embodiment, the case where the transmission device 100 is arranged corresponding to each fuel supply device 16 has been described as an example. However, the present invention is not limited to this. For example, the transmitter is attached to a membership card distributed to each customer. The relative distance between the customer position and the nozzle may be detected. In that case, it is also possible that multiple customers have the same membership card, so the customer's membership card can be read by having the card reader read the customer information stored in the membership card before starting fuel supply. What is necessary is just to comprise so that the position of may be identified.

  Moreover, in the said Example, fuel supply was stopped by stopping a pump or closing a solenoid valve. However, the stop of fuel supply is not limited to this. For example, a mechanical shutoff valve may be provided in the fuel supply path instead of the electromagnetic valve, and the fuel supply may be stopped by opening and closing the shutoff valve.

  Further, in the above-described embodiment, as an example of the stop determination unit that detects whether or not the fuel supply from the nozzle has been stopped, detection is performed using a flow rate pulse from the flow meter. However, the stop determination means is not limited to this. For example, you may make it detect whether the fuel supply from a nozzle was stopped by the measured value of the flowmeter.
