Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refueling device, and more particularly to a refueling device configured to measure a refueling amount discharged from a refueling nozzle and refuel a preset target refueling amount.

[0002]

2. Description of the Related Art For example, a plurality of weighing machines are installed in a gas station or the like. Each weighing machine is provided with a refueling nozzle for regular gasoline, high-octane gasoline, and light oil. In this type of weighing machine, a preset value desired by the customer, such as a fixed amount or a fixed amount, is set in advance, and when the measured value reaches the preset value, refueling ends. Generally, a weighing machine is provided on a pump for sending an oil liquid, a flow meter for measuring a refueled flow rate, a two-stage solenoid valve (for a large flow rate, for a small flow rate), a refueling hose, a refueling nozzle, and a nozzle hook. A refueling nozzle, a setter for setting the amount or amount of refueling as a preset value, a display for displaying the refueling amount discharged from the refueling nozzle, and the like.

In a weighing machine having a preset refueling function,
Execute the preset refueling process in the following procedure. Set the preset value using the setting device. And P
It receives a refueling permission message from the OS terminal. When the nozzle switch is turned on, the pump is started and the solenoid valve (for large flow rate) is opened. Reset the measurement value of the display unit.

[0004] Refueling is started by a refueling nozzle. The measured value output from the flow meter is displayed on the display. The solenoid valve (for large flow rate) is closed 0.5 liters before the preset value, and the solenoid valve (for small flow rate) is opened to refuel the remaining amount up to the preset value. When the measured value of the flow meter reaches the preset value, the solenoid valve (for small flow rate) is closed and the pump is stopped.

When the refueling nozzle is returned to the nozzle hook and the nozzle switch is turned off, a message indicating refueling end is output to the POS terminal.

[0006]

In the conventional lubricating apparatus configured as described above, foreign matter may be caught between the valve of the solenoid valve and the valve seat, and the clearance between the solenoid valve and the valve seat may be reduced due to aging. If it goes wrong, even if the measured value reaches the preset value and the solenoid valve is closed, the solenoid valve is not actually closed and the measured value sometimes exceeds the preset value.

When replenishing the tank in such a state,
The driver performs the payment using the value displayed on the display as the refueled flow rate value.In the case of preset refueling, the difference between the set refueling amount and the value displayed on the display is different. A trouble may occur between the driver and the gas station. For example, when a numerical value equal to or more than the set preset value is displayed on the display, the driver pays more than the planned amount, and the driver is dissatisfied.

[0008] Therefore, an object of the present invention is to provide a refueling device that solves the above-mentioned problems.

[0009]

The present invention has the following features to solve the above-mentioned problems. According to the first aspect of the present invention, there is provided a flowmeter for measuring a refueling amount discharged from a refueling nozzle, a display for displaying a total refueling value measured by the flowmeter, and a preset for setting a refueling value to be refueled. A refueling device having an operation unit and control means for stopping refueling when a target refueling value set by the preset operation unit is measured by the flow meter, wherein the refueling is stopped when refueling is stopped by the control means. Determining means for determining whether or not there is an error exceeding a total refueling value measured by a meter and a target refueling value set by the preset operation unit; and abnormal when the determining means determines that the refueling error is equal to or more than a predetermined value. And a notifying means for notifying occurrence.

Therefore, according to the first aspect of the present invention, it is determined whether there is an error exceeding the total refueling value measured by the flow meter and the target refueling value set by the preset operation unit when refueling is stopped, By notifying the occurrence of an abnormality when it is determined that the refueling error is equal to or greater than the predetermined value, the refueling station can recognize that some abnormality has occurred in the refueling system and deal with it.

[0011] The second aspect of the present invention is directed to the first aspect.
In the refueling system described above, the refueling prohibition means for prohibiting refueling from the next time when the determination means determines that the refueling error is equal to or more than a predetermined value is provided. Therefore, according to the second aspect of the present invention, when it is determined that the refueling error is equal to or more than the predetermined value, refueling is prohibited from the next time. Can be prevented to prevent reoccurrence of troubles with customers.

Here, an operation procedure of self-service refueling in the present embodiment will be described. FIG. 5 is a flowchart for explaining a refueling procedure between the devices when performing self-service refueling.

As shown in FIG. 5, the customer arriving at the gas station moves to an empty fueling point among fueling points No. 1 to No. 8 in (operation 10). Then, the vehicle is stopped at an empty refueling point. Next (Action 1)
In 1), the refueling conditions such as the type of oil to be refueled, the refueling value, and the payment method are set using the setting unit 25 of the self-service unit 18 installed at the refueling point.

In the next (operation 12), after the setting is completed, the customer removes the fueling nozzle 27 from the weighing machine 17 and inserts the discharge pipe of the fueling nozzle 27 into the fueling port of the vehicle. Then, in (operation 13), refueling is terminated, and the refueling nozzle 27 is returned to the weighing machine 17. Further, the customer carries the temporary slip issued from the printer 26 in (operation 14) and goes to a checkout station to settle the refueling fee. Then, in (operation 15), the customer leaves the gas station.

The self-service unit 18 executes the following processing in conjunction with the customer (operations 10 to 15). That is, when the customer enters the refueling point, the self-service unit 18 enters a standby mode of waiting for a setting start in step S11 (hereinafter, “step” is omitted). In this case, the weighing machine 17 may be provided with some vehicle detection device, and the signal may be received by the self-service unit 18. However, the setting may be awaited when the previously refueled vehicle leaves the refueling point.

When the customer finishes the setting operation, S1
At 2, the set value is transmitted to the gas station control device 13. The printer 26 receives a print command from the gas station control device 13 in S13, and issues a temporary slip on which the slip number and the like are printed in accordance with the set format. In addition, (operation 1)
The gas station control device 13 executes the following processing in conjunction with 0-15). That is, the gas station control device 13
Is the setting unit 2 of the self-service unit 18 in S14.
When various settings are transmitted from 5 and a permission button (not shown) is turned on, refueling permission is given to the weighing machine 17.

In the next S15, when the refueling end and the refueling amount are transmitted from the weighing machine 17, the total amount is calculated. Then, in S16, the amount, the slip number, and the like are transmitted to the printer, and printing is instructed. On the other hand, in the weighing machine, when the refueling permission is obtained from the refueling station control device 13 in S17, the waiting time starts from the refueling start. In S18, when the customer starts refueling, the pump is operated, and fuel is supplied from the refueling nozzle 27 to the fuel tank of the vehicle. In the next S19, when the customer finishes refueling, the pump is stopped, and the refueling end and the refueling amount are transmitted to the gas station control device 13.

When the refueling is completed, the customer uses the printer 26 of the self-service unit 18 to supply refueling data such as a refueling point number or a weighing machine number, an additional number (a slip number), a date and time, an oil type, a refueling amount, and a refueling amount. Take the temporary slip with displayed and move to the checkout office in the office. The operation procedure for performing self-service refueling is now completed. The setting contents input by the setting unit 25 of the self-service unit 18 are simultaneously displayed on the display device 4 of the gas station control device 13.
6 is displayed. For this reason, the staff of the gas station is required to display the display device 46 of the gas station control device 13 installed in the office of the gas station.
Thereby, the presence or absence of the setting of each of the weighing machines 17 _{1 to} 17 _n and the setting contents can be confirmed.

Also, the staff at the gas station receives the temporary slip from the fueling customer and selects data corresponding to the contents from the screen displayed on the display device 46 of the gas station control device 13,
The payment operation is performed by the input device 47. Thus, the refueling data is transmitted from the gas station control device 13 to the POS terminal 15. As a result, a slip is issued from the printer (not shown) of the POS terminal 15, and the slip is handed to the customer in exchange for the refueling fee.

[0034] In the case where the ATM is installed in the vicinity of the weighing machine 17 ₁ to 17 _n, the issuance of documents is not performed, incidental fueling fee is carried out in situ. Next, weighing machine 1
7 will be described. FIG. 6 is a flowchart of a process of analyzing the refueling permission message transmitted from the POS terminal 15.

As shown in FIG. 6, the control circuit 37
When a refueling permission message is received from the POS terminal 15, S
At 21, the presence / absence of a preset, a limit amount, and unit price data per liter are read from a refueling permission message. Next S
If it is determined in Step 22 that the refueling permission message has a preset and a limit amount, the process proceeds to S23, and the type of the preset is confirmed. If the preset amount is set in S23, the process proceeds to S24, and the target refueling amount is set to the designated refueling amount (preset amount).

In the next step S25, it is checked whether the target refueling amount is 0.1 liter or less. If the target refueling amount is not less than 0.1 liter in S25, S
Proceeding to 26, the refueling permission is set, and the current processing ends. If there is no preset or limited amount in the refueling permission message in S22, the process proceeds to S27, and the target refueling amount is set to zero liter. Then, the process proceeds to S26, in which refueling permission is set, and the current process ends.

If it is determined in step S23 that the preset amount has been set, the flow advances to step S28 to check whether the unit price data per liter is equal to or more than zero yen. If the unit price data per liter is equal to or more than zero yen in S28, the process proceeds to S29, and the preset amount of money is divided by the unit price data to calculate the target refueling amount. afterwards,
The processing of S25 and S26 described above is executed.

If the unit price data per liter is equal to or less than zero yen in S28, the process proceeds to S30.
A set value error is set, and in S31, no refueling permission is set. FIG. 7 is a flowchart of the refueling pre-processing executed by the control circuit 37. As shown in FIG. 7, the control circuit 37 determines in S41 that the nozzle switch 3
Check if 0 is on. That is, when the nozzle switch 30 is ON, the refueling nozzle 27 is hooked on the nozzle hook 29, and the process proceeds to S42. In the next step S42, it is checked whether or not refueling is permitted.
Then, in S42, if there is a fueling permission, S4
Proceed to 3 to check whether the various switches, sensors, and abnormality flags are normal.

In S43, various switches, sensors,
If the abnormality flag is normal, the process proceeds to S44, where the pump motor 38 of the pump 34 is turned on. Subsequently, in S45,
The solenoid valve 36 is opened. In the next S46, the flowmeter 35
Checks whether the measured value is less than the minimum lubrication amount, and if the measured value is less than the minimum lubrication amount,
Proceed to S47. In S47, the target refueling amount and the target refueling amount are reset. Then, in S48, since the conditions before refueling have been cleared, processing during refueling described later (FIG. 8)
See).

In step S41, the nozzle hook 29
If the nozzle switch 30 is off, or if refueling is not permitted in S42, or if various switches, sensors, and abnormality flags are abnormal in S43, S4
Proceeding to 9, the electromagnetic valve 36 is closed to stop refueling. Then, in S50, the pump motor 38 of the pump 34 is turned off and the pump 34 is stopped.

FIG. 8 is a flowchart of the refueling process executed by the control circuit 37. Note that the control circuit 37 repeatedly executes the processing shown in FIG. 8 at predetermined time intervals. As shown in FIG. 8, when performing the processing during refueling, the control circuit 37
First, in S51, it is checked whether or not the nozzle switch 30 of the nozzle holder 29 is turned on, or whether or not an emergency stop switch (not shown) is turned on.

In S51, the nozzle switch 30 of the nozzle hook 29 is turned off, and the emergency stop switch (not shown)
Is OFF, there is no abnormality, so the process proceeds to S52 and the flow meter 3
Check if the flow pulse from 5 is stopped. In step S52, when the flow rate pulse is output from the flow meter 35, the preset refueling is continued, so the process proceeds to step S53, where the measurement value (total refueling amount) measured by the flow meter 35 is set to the preset target. Check whether the refueling amount is obtained by subtracting 0.5 liter from the refueling amount.

In S53, if the measured value (total refueling amount) measured by the flow meter 35 while the preset refueling is continued reaches the refueling amount obtained by subtracting 0.5 liter from the target refueling amount, the preset value is set. Therefore, the process proceeds to S54, in which the solenoid valve 36 is closed to forcibly stop the preset refueling. In the next S55, it is checked whether or not a value obtained by adding a rounding width (for example, 0.25% of the target refueling amount) to the preset target refueling amount is equal to or less than a measured value.

In S55, when the measured value (total refueling amount) measured by the flow meter is equal to or larger than the value obtained by adding the rounding width (for example, 0.25% of the target refueling amount) to the preset target refueling amount, Since the refueling amount exceeds the preset value, the process proceeds to S56, where display data is created from the measured value.
In the next step S57, an abnormality display, which will be described later, is requested (FIG. 10).
Display) to prevent the next refueling.
A message such as "Prohibition of refueling, check of solenoid valve and flow meter" is displayed at 0. Subsequently, in S58, the preset stop abnormality flag is turned on. Then, the above S5
Return to 1.

In step S51, the nozzle hook 2
If the nozzle switch 30 of No. 9 is on or the emergency stop switch (not shown) is on, there is some abnormality, so the process proceeds to S60, where the solenoid valve 36 is closed to stop refueling. Subsequently, in S61, the pump motor 38 of the pump 34 is turned off to stop the pump 34. Next S6
In 2, it is confirmed that the flow rate pulse transmitted from the pulse transmitter 39 of the flow meter 35 has stopped. If the flow rate pulse has not stopped in S62, the process proceeds to S63, in which an abnormality is notified and an instruction to turn off the power of the weighing machine 17 is issued.
If the flow rate pulse is stopped in S62, the process proceeds to S64, shifts to refueling stop processing, and ends the current processing.

In step S52, when the flow rate pulse from the flowmeter 35 is stopped, the preset refueling has been completed, so the flow proceeds to S64 to shift to refueling stop processing. Let it. In S53, when the measured value (total refueling amount) measured by the flow meter 35 does not reach the refueling amount obtained by subtracting 0.5 liter from the target refueling amount, the current process is terminated.

In step S55, the measured value (total refueling amount) measured by the flow meter is equal to or less than a value obtained by adding a rounding width (for example, 0.25% of the target refueling amount) to the preset target refueling amount. At this time, since the refueling amount does not exceed the preset value, the process proceeds to S65, where the display data on the display 40 is changed to the preset data (target refueling amount), and the process proceeds to S66.
To request the display of the end of the preset,
Is displayed, and the process returns to S51.

FIG. 9 is a flowchart of the error reset request processing. As shown in FIG.
When an error reset request is received from the remote controller 32, the CPU checks in S71 whether a preset stop abnormality has occurred. If a preset stop abnormality has occurred in S71, the process proceeds to S72, and the preset stop abnormality flag is reset. Further, if no preset stop abnormality has occurred in S71, the process of S72 is omitted.

FIG. 10 is a flowchart of the preset stop abnormality display processing. As shown in FIG. 10, when the preset stop abnormality flag is set, the control circuit 37 checks whether or not the refueling nozzle 27 has been removed from the nozzle hook 29 in S81. In S81, when the nozzle switch 30 of the nozzle hook 29 is turned off, it is determined that the refueling nozzle 27 has been removed from the nozzle hook 29, and the process proceeds to S82 to display an error message on the display 40 flickering.

When the customer who does not notice that the preset stop abnormality flag is set removes the refueling nozzle 27 from the nozzle hook 29, an error message is displayed on the display unit 40 by flickering, and the customer can measure the measurement. The refueling operation is interrupted by noticing that an abnormality has occurred in the machine 17. In S81, when the nozzle switch 30 of the nozzle hook 29 is on, the refueling nozzle 2
It is determined that 7 has been returned to the nozzle hook 29, and the flow advances to S83 to display the previous refueling data on the display 40.

FIG. 11 is a flowchart of the preset stop abnormality display processing executed by the POS terminal 15. FIG.
As shown in FIG. 1, the control circuit (not shown) of the POS terminal 15 checks whether or not the preset stop abnormality flag is turned on in each weighing machine 17 in S91. In S91, when the preset stop abnormality flag is ON, the process proceeds to S92, and the display of the vehicle guidance device (not shown) of the gas station corresponding to the weighing machine 17 is switched to "no refueling".

Subsequently, in S93, the occurrence of the abnormality is notified to the maintenance company of the refueling device via a telephone line. Thereby, after receiving the notification that the abnormality has occurred in the weighing machine 17, the maintenance company dispatches the maintenance staff to the gas station, and immediately performs the work of finding the fault location and the repair work of the fault location. When the preset stop abnormality flag is set, the customer's vehicle is
In order to prevent refueling, the display of a vehicle guidance device (not shown) is prohibited from refueling so that the next customer will not refuel.

In the above-described embodiment, the above-described oil supply device of the ground installation type is taken as an example. However, the present invention is not limited to this, and it is needless to say that the present invention can be applied to a suspension type oil supply device in which the oil supply nozzle is moved up and down.

[0054]

As described above, according to the first aspect of the present invention, when the refueling is stopped, the difference between the total refueling amount measured by the flow meter and the target refueling value set by the preset operation unit is exceeded. By judging the presence / absence and notifying the occurrence of an abnormality when it is determined that the refueling error is equal to or more than a predetermined value, the refueling station can recognize that some abnormality has occurred in the refueling system and can deal with it. . Therefore, in the case of the preset refueling, since the set target refueling value is different from the numerical value displayed on the display, it is possible to prevent a trouble between the driver and the refueling station at the time of settlement.

According to the second aspect of the present invention,
When the refueling error is determined to be equal to or greater than the predetermined value, refueling is prohibited from the next time, so even if any abnormality occurs in the solenoid valve of the weighing machine, refueling can be prohibited to prevent recurrence of trouble with customers. . Since the use of the failed weighing machine is prohibited, it is possible to prevent the trouble with the customer from recurring. Further, it is possible to promptly contact the maintenance company, and the maintenance staff can keep track of the failure state, so that the cause of the failure can be quickly pursued.
