[0001]
BACKGROUND OF THE INVENTION
  The present invention is for gas station managementsystemIn particular, the service station management system is designed so that the refueling work can be performed efficiently, especially when refueling at multiple refueling points simultaneously.systemAbout.
[0002]
[Prior art]
For example, a plurality of measuring machines are installed in a gas station or the like. Each metering machine is provided with refueling nozzles for regular gasoline, high-octane gasoline, and light oil. In addition, in a gas station where this type of metering machine is installed, (1) a full-service oiling system in which workers at the gas station operate the fuel nozzle operation, window cleaning, and ashtray cleaning; Semi-self-service lubrication system in which workers at the gas station perform the lubrication nozzle operation when setting operation is performed, and (3) Self-service lubrication system in which the driver performs the lubrication setting operation, lubrication nozzle operation, window cleaning, and ashtray cleaning. is there.
[0003]
In any of the above oil supply methods (1) to (3), when the oil type to be supplied and the oil supply amount are set and operated, the oil supply nozzle removed from the nozzle hook is inserted into the oil supply port of the vehicle and the oil supply is performed. Done. When the preset preset value or full tank fueling is completed, the fueling nozzle is removed from the fueling port and returned to the nozzle hook. Thereafter, a slip printed with the type of oil supplied, the amount of oil supplied, the amount of oil supplied, etc. is issued and the fee is settled.
[0004]
[Problems to be solved by the invention]
However, in the conventional service station, in the case of the full service lubrication system and the semi-self service service system, when the preset value or full tank is completed, an operator at the service station removes the fuel nozzle from the fuel filler port. Perform the operation to return to the hook. In general, a worker at a gas station is responsible for a plurality of fueling points (usually two measuring machines) and performs a fueling operation in the order of arrival at the fueling points.
[0005]
Therefore, when refueling a vehicle at a plurality of refueling points at the same time, the driver of another vehicle waits until the refueling nozzle return operation or window wiping, ashtray cleaning, etc. to the vehicle that has arrived first ends. Become. In other words, when the service to the first arriving vehicle is being performed and the refueling of the second arriving vehicle is completed and the metering machine is stopped, the second vehicle driver arrives first. There is a problem that time is wasted just waiting without doing anything until the service to the finished vehicle is completed.
[0006]
In the case of the self-service refueling method, the driver himself operates the refueling nozzle, so there is no waiting time in the state where preset refueling or full tank refueling is completed even if multiple vehicles refuel simultaneously. When the fuel is settled, a plurality of drivers are waiting in line at the filling station office, and there is a problem that it takes extra time for the driver to finish paying the fuel charge.
[0007]
  Therefore, the present invention is a gas station management that solves the above problems.systemThe purpose is to provide.

[0019]
Also, the weighing machine 12₁, 12₂An external POS 14 is provided adjacent to the POS 14. The weighing machine 12 is located above the external POS 14.₁, 12₂A display lamp 15 is provided for displaying the operating states (refueling, refueling end, standby, etc.) of the respective refueling points P1 to P3 by color.
FIG. 3 is a configuration diagram for explaining a schematic configuration of the weighing machine.
[0020]
As shown in FIG. 3, the weighing machine 12 has an oil supply path 17 for each oil type (for example, regular gasoline, high-octane gasoline, light oil, etc.), and the oil supply path 17 includes an underground tank (not shown). An inserted oil supply line 18, a pump 19 provided in the oil supply line 18, a flow meter 21, and a flow rate adjusting valve 23 are disposed.
An oil supply hose 25 and an oil supply nozzle 27 are provided at the end of the oil supply system path 17. The oil filler nozzle 27 is hooked on a nozzle hook 29 provided on the side surface of the weighing machine 12 when not fueled. The nozzle hook 29 is provided with a nozzle switch 31 that detects the presence or absence of the fueling nozzle 27. Furthermore, the weighing machine 12 is provided with a preset input unit 32 for inputting the oil type and the oil supply amount.
[0021]
The control circuit 33 of the weighing machine 12 activates the motor 19 a of the pump 19 based on the detection signal from the nozzle switch 31 and opens the flow rate adjustment valve 23. Further, when the fuel supply nozzle 27 is opened to start the fuel supply, the flow rate pulse output from the pulse transmitter 21 a of the flow meter 21 is counted and the integrated flow rate is displayed on the flow rate display 35.
[0022]
When the preset value set by the operation of the preset input unit 32 is supplied, the control circuit 33 closes the flow rate adjustment valve 23 and stops the motor 19a of the pump 19. Further, the control circuit 33 adjusts the valve opening degree of the flow rate adjusting valve 23 by a control signal from the fuel supply management device 11 as will be described later, and controls the flow rate (flow velocity) supplied to the fuel tank (not shown) of the vehicle. Change the flow rate.
[0023]
Here, the configuration of the fuel supply management device 11 will be described.
FIG. 4 is a front view of the fuel supply management device 11. FIG. 5 is a block diagram showing the configuration of the fuel supply management device 11.
As shown in FIGS. 4 and 5, the refueling management device 11 includes a CPU 34 that performs arithmetic processing, a memory 35 that stores each data, and each weighing machine 12 via the communication cable 13.₁~ 12_nAn input / output unit 36 for transmitting / receiving signals to / from the liquid crystal display, a liquid crystal display (display means) 37 for displaying the refueling status at the refueling point of each measuring machine 12, and an operation in which a gas station staff performs flow rate adjustment operations. Part (operation means) 39. The liquid crystal display 37 displays a set value (preset value) for each oil supply point, a remaining oil supply time, a flow rate (flow velocity) of the oil liquid to be supplied, and whether or not the flow rate (flow velocity) has increased.
[0024]
Moreover, the display of the remaining oil supply time of the liquid crystal display 37 is displayed in analog by the length of the horizontal bar graph. Therefore, even when refueling at a plurality of refueling points at the same time, the remaining refueling time at each refueling point can be confirmed at a glance.
The operation unit 39 includes flow rate adjustment operation buttons 41a to 41h and 42a to 42h for adjusting the flow rate (flow velocity) supplied from the fuel supply nozzle 27 to the fuel tank (not shown) of the vehicle, and an emergency stop. Operation buttons 44a to 44h are provided. The flow rate adjusting operation buttons 41a to 41h are switch buttons operated when increasing the flow rate (flow velocity), and the flow rate adjusting operation buttons 42a to 42h are switch buttons operated when decreasing the flow rate (flow velocity). is there.
[0025]
  Accordingly, when refueling is simultaneously performed at a plurality of refueling points, the flow rate adjusting operation buttons 41a to 41h are set so that a predetermined time difference is generated at the refueling point that started refueling earlier than the refueling point that started refueling later. , 42a to 42h. That is, it adjusts so that the valve opening degree of the flow control valve 23 of the said measuring machine 12 may be restrict | squeezed so that the flow volume (flow velocity) supplied at the oil supply point of a back | latter stage may become small flow volume.(This flow rate adjustment by manual operation is a premise example of the present invention.)
[0026]
  Thereby, even if refueling is performed at a plurality of refueling points, the refueling is finished every predetermined time. Therefore, it is prevented that the user waits until the service to the vehicle that has been refueled is finished even though the refueling has been completed.
  Next, control processing executed by the control circuit 33 of the weighing machine 12 will be described.
  FIG.It is a premise of the present inventionIt is a flowchart which shows the procedure of the control process which the control circuit 33 of the weighing machine 12 performs. Note that the control process of FIG. 6 is repeatedly executed at predetermined time intervals.
[0027]
As shown in FIG. 6, the control circuit 33 checks the presence or absence of a preset input from the preset input unit 32 in step S <b> 11 (hereinafter, “step” is omitted). In S11, when a preset value is input from the preset input unit 32, the process proceeds to S12, and it is checked whether the nozzle switch 31 of the nozzle hook 29 is turned on.
[0028]
In S12, when the nozzle switch 31 is turned on, it is determined that the fuel nozzle 27 is removed from the nozzle hook 29 and inserted into the fuel filler of the vehicle, the process proceeds to S13, and the motor 19a of the pump 19 is activated. . Subsequently, the flow rate adjusting valve 23 is opened in S14.
In next S15, it is checked whether or not a control signal from the fuel supply management device 11 is input. The staff of the gas station operates the operation unit so as to reduce the flow rate (flow velocity) at the oiling point where the oiling is started later so that the remaining oiling time at each oiling point displayed on the liquid crystal display 37 does not become the same time. 39, the flow rate adjusting operation buttons 42a to 42h are operated. When the flow rate adjustment operation buttons 42 a to 42 h of the operation unit 39 are operated, a control signal from the fuel supply management device 11 is input to the control circuit 33 of the weighing machine 12.
[0029]
When the control signal from the fuel supply management device 11 is input in S15, the process proceeds to S16, and the valve opening degree of the flow rate adjusting valve 23 is adjusted according to the control signal (oil supply amount control means). In this case, the flow rate of the oil liquid is decreased by reducing the valve opening degree of the flow rate adjusting valve 23. Thereby, it can adjust so that the end of refueling in a plurality of refueling points may become every predetermined time interval. Therefore, when the refueling time at a plurality of refueling points is substantially the same, the refueling flow rate of each metering machine 12 can be changed, so that efficient refueling station operation is possible regardless of the order.
[0030]
In the next S17, the flow rate pulse output from the flow meter 21 is counted and the integrated flow rate is displayed on the flow rate display 35. In S18, it is checked whether or not the integrated flow rate measured by the flow meter 21 has reached a preset value. In S18, the processes 15 to 18 are repeatedly executed until the integrated flow rate measured by the flow meter 21 reaches a preset value. When the integrated flow measured by the flow meter 21 reaches a preset value, the process proceeds to S19, and it is checked whether the nozzle switch 31 of the nozzle hook 29 has been turned off.
[0031]
When the nozzle switch 31 is turned off in S19, it is confirmed that the fuel supply nozzle 27 is returned to the nozzle hook 29 and the fuel supply is completed. Next, in S20, the motor 19a of the pump 19 is stopped, and in S21, the flow rate adjusting valve 23 is closed.
If the preset value is not input from the preset input unit 32 in S11, the process proceeds to S22 to check whether the nozzle switch 31 of the nozzle hook 29 is turned on. When the nozzle switch 31 is turned on in S22, it is determined that the tank is full of fuel, and the motor 19a of the pump 19 is started in S23. Subsequently, the flow rate adjusting valve 23 is opened in S24. In the case of full tank refueling, since the remaining time of refueling is unknown, the flow control by the refueling management device 11 is not performed, and the process proceeds to S19 described above.
[0032]
In S22, when the nozzle switch 31 of the nozzle hook 29 is OFF, it is determined that the refueling operation is not performed, and the process returns to S11.
In this way, by operating the flow rate adjustment operation buttons 42a to 42h of the operation unit 39 provided in the oil supply management device 11, the valve opening degree of the flow rate adjustment valve 23 at the oil supply point where the oil supply is started later is reduced. Therefore, even when refueling is performed at a plurality of refueling points, the refueling end time at each refueling point can be shifted by a predetermined time. Therefore, in the case of the full service refueling method or semi-self service refueling method, the waiting time until the service at the refueling point that started refueling is completed by delaying the refueling end time at the refueling point that started refueling later Can be shortened.
[0033]
In addition, in a gas station that employs the self-service fueling method, the settlement waiting time when the fueling fee is settled can be averaged and shortened.
Further, in the fuel supply management device 11, when the flow rate adjustment operation buttons 42a to 42h of the operation unit 39 are operated and the valve opening degree of the flow rate adjustment valve 23 is reduced for a predetermined time (for example, 5 minutes) or more, the flow rate is automatically adjusted. Control is performed so that the valve opening of the adjusting valve 23 is fully opened and the oil supply delay is not excessive.
[0034]
  Here, an embodiment of a gas station management system according to the present invention will be described.
  FIG. 7 illustrates the present invention.Control processing executed by the fuel management device 11 of the gas station management systemIt is a flowchart for demonstrating. As shown in FIG. 7, the refueling management apparatus 11 checks whether or not a preset value is input from the preset input unit 32 in S31. In S31, when there is an input of a preset value, the process proceeds to S32, and the refueling point at which the preset input has been made is determined. In the next S33, the order of refueling start is registered in the memory 35.
[0035]
FIG. 8 is a diagram schematically showing a refueling order data table stored in the memory 35.
As shown in FIG. 8, when the process shown in FIG. 6 is executed, the order of the refueling points for which preset input has been made is registered in the refueling order data table 46 registered in the memory 35. This refueling order is determined by the time when preset input is performed, and the refueling point number is automatically registered in the last order.
[0036]
  When the refueling is completed and the refueling nozzle 27 is returned to the nozzle hook 29, the refueling at the refueling point is “finished”. Then, when refueling at the previously registered refueling point is completed, the order of the next registered refueling point is advanced.
  FIG. 9 shows a valve opening degree control process (oil supply amount control means) executed by the control circuit 33 of the weighing machine 12.ExampleIt is a flowchart for demonstrating.
[0037]
As shown in FIG. 9, in S41, it is checked whether or not there are two or more refueling points currently registered in the refueling rank data table 46 during the preset refueling. In S41, when there are two or more refueling points during preset refueling, the process proceeds to S42 to check whether the priority order of the refueling points registered in the refueling rank data table 46 is the first. And when the priority of the said fueling point is No. 1, it progresses to S43 and makes the valve opening degree of the flow regulating valve 23 large. Further, in S41, when the number of refueling points during preset refueling is currently 1, since there is no need to adjust the flow rate, the process of S42 is omitted and the process of S43 is executed.
[0038]
In S42, when there are two or more refueling points during preset refueling, but the priority of the refueling points registered in the refueling rank data table 46 is not No. 1, the process proceeds to S44, and the refueling rank data table 46 It is checked whether or not the priority order of the refueling point registered in No. 2 is No. 2. And when the priority of the said fueling point is No. 2, it progresses to S45 and makes the valve opening degree of the flow regulating valve 23 into the inside.
[0039]
In S44, when the priority of the refueling point is not the second, the process proceeds to S46 to check whether the priority of the refueling point registered in the refueling rank data table 46 is the third. And when the priority of the said oiling point is No. 3, it progresses to S47 and makes the valve opening degree of the flow regulating valve 23 small.
In S46, when the priority of the fueling point is not the third, the process returns to S41 again, and the processes after S41 are repeated.
[0040]
In this way, the control circuit 33 of the measuring machine 12 automatically adjusts the valve opening degree of the flow rate adjusting valve 23 while constantly checking the priority of the refueling points registered in the refueling rank data table 46. is doing.
That is, since the flow rate of the flow rate adjusting valve 23 of the second and third oil supply points with low priority that has started refueling can be reduced in stages, the flow rate of the oil can be reduced. Even when refueling is performed at points, the refueling end time at each refueling point can be shifted by a predetermined time. Therefore, by delaying the refueling end time at the second and third refueling points with low priority, in the case of the full service refueling method or the semi-self service refueling method, the service at the refueling point where refueling started first is completed. Can be shortened.
[0041]
Moreover, since the flow rate is changed so that the respective oil supply orders at the respective oil supply points are different, the driver of the vehicle, which is a customer, is not given discomfort due to the different end orders.
And when there are a plurality of preset fueling points during preset fueling, in order to adjust the valve opening degree of the flow rate adjusting valve 23 to the valve opening degree according to the priority order at that time, the staff of the gas filling station There is no need to monitor the refueling situation at the plant, saving labor.
[0042]
  In addition, in a gas station that employs the self-service fueling method, the settlement waiting time when the fueling fee is settled can be averaged and shortened.

Next, the weighing machine 57₁~ 57_nA control process executed by the control circuit 74 will be described.
[0051]
FIG. 12 is a flowchart for explaining the lamp / buzzer monitoring control process.
As shown in FIG. 12, in S51, it is checked whether or not refueling by a self-service refueling system in which the customer himself performs a refueling operation is performed. When the self-service refueling method is used in S51, the process proceeds to S52, where the parameter A for constant time monitoring and the parameter B for quantitative monitoring are compared.
[0052]
In this parameter A, any one of determination results 1 to 4 determined at any time in the fixed time monitoring determination process of FIG. 14 described later is set. In addition, any one of determination results 1 to 4 determined at any time in the quantitative monitoring determination process of FIG. Accordingly, in S52, the determination result values set in the parameters A and B are compared, and the ramp / buzzer control is performed for the larger value.
[0053]
That is, in S52, when A> B, the process proceeds to S53, and the determination result of the fixed time monitoring is set. In S52, if A ≦ B, the process proceeds to S54, and the determination result of quantitative monitoring is set.
In the next step S55, monitoring control (details will be described later) of the lamp / buzzer used in the self-service fueling system is executed according to the determination result of the constant time monitoring or the determination result of the quantitative monitoring.
[0054]
If the full service refueling system in which the operator at the gas station performs the refueling operation instead of the self-service refueling system in S51, the process proceeds to S56 and the small crew control used in the full service refueling system is executed. This small crew control is a lamp / buzzer control for semi-self service lubrication in which the operator at the gas station only performs the operation of the fuel nozzle and full service lubrication in which the operator at the gas station performs all the lubrication operations. A lamp is lit or a buzzer is sounded to notify a worker at a gas station that refueling has been completed at the end of refueling or when refueling is stopped by an auto-stop mechanism provided in a refueling nozzle.
[0055]
FIG. 13 is a flowchart for explaining the lamp / buzzer determination control processing.
As shown in FIG. 13, in S61, it is checked whether or not the determination result is 1. When the determination result by the determination process described later in S61 is 1, the process proceeds to S62, and only the blue lamp 72a is turned on. In step S63, the buzzer 73 is turned off.
[0056]
In S61, when the determination result is not 1, the process proceeds to S64, and it is checked whether the determination result by the determination process described later is 2. When the determination result is 2 in S64, the process proceeds to S65, and the blue lamp 72a and the yellow lamp 72b are turned on. In S66, the buzzer 73 is turned off.
In S64, when the determination result is not 2, the process proceeds to S67, and it is checked whether the determination result by the determination process described later is 3. When the determination result is 3 in S67, the process proceeds to S68 and only the yellow lamp 72b is turned on. In S69, the buzzer 73 is turned on at intervals of 2 seconds to generate a buzzer sound.
[0057]
If the determination result is not 3 in S67, the process proceeds to S70 to check whether the determination result by the determination process described later is 4. When the determination result is 4 in S70, the process proceeds to S71, and the yellow lamp 72b and the red lamp 72c are turned on. In S72, the buzzer 73 is turned on at 1 second intervals to generate a buzzer sound.
In S70, when the determination result is not 4, the process proceeds to S73, and it is checked whether or not the determination result by the determination process described later is 5. When the determination result is 5 in S73, the process proceeds to S74, and the red lamp 72c is turned on. In step S75, the buzzer 73 is turned off.

If the refueling time is not less than 2 minutes in S91, the process proceeds to S93 to check whether the refueling time is 2 to 3 minutes. When the refueling time is 2 to 3 minutes in S93, the process proceeds to S94 and the determination result 2 is set.
[0063]
If it is determined in S93 that the refueling time is not 2 to 3 minutes, the process proceeds to S95 to check whether the refueling time is 3 to 3.5 minutes. When the refueling time is 3 to 3.5 minutes in S95, the process proceeds to S96 and the determination result 3 is set.
In S95, if the refueling time is not 3 to 3.5 minutes, the process proceeds to S97 to check whether the refueling time is 3.5 to 4 minutes. When the refueling time is 3.5 to 4 minutes in S97, the process proceeds to S98 and the determination result 4 is set.
[0064]
In S97, when the refueling time is not 3.5 to 4 minutes, the process proceeds to S99 and the determination result 5 is set.
Thus, since the determination result according to the refueling time for self-service refueling is automatically set, as described above, in the process of FIG. 13, the lamps 72a to 72c are selectively turned on according to the refueling time. When the buzzer 73 is turned on at predetermined time intervals, each weighing machine 57 is turned on.₁~ 57_nThe progress of refueling can be notified.

【The invention's effect】
  As described above, according to the invention described in claim 1,Reads the priority of the weighing machine to be refueled from the memory, and controls the flow rate of the weighing machine so that the flow rate is lower than the refueling flow rate of the weighing machine with a higher priority than the priority level.Therefore, in the case of the full-service refueling system or the semi-self-service refueling system, it is possible to delay the refueling by reducing the flow rate of fuel supplied to the second and third refueling vehicles. It can be adjusted so that the refueling of the vehicle that has started the refueling is finished as the refueling and service of the vehicle are finished. In addition, in a gas station that employs the self-service fueling method, the settlement waiting time when the fueling fee is settled can be averaged and shortened.
