Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an oil supply device for supplying an oil liquid such as gasoline to a fuel tank of a vehicle, and in particular, by setting an amount of oil supply, an amount of oil supply, and the like in advance, The present invention relates to an oil supply device having a preset oil supply function for performing a fixed amount oil supply for the set amount.

[Conventional technology]

Generally, in order to perform a refueling operation using a refueling device having a preset refueling function, the refueling amount or the refueling amount desired by the customer is preset by the preset device before refueling, and then the refueling nozzle is connected to the fuel tank. The oil in the oil storage tank is discharged from the oil supply nozzle through the pump, flow meter, and hose when the valve is inserted into the tank and the valve is opened, and the pump motor automatically stops when the actual amount of oil supply matches the preset value. The metering or refueling is executed by automatically closing the stop valve or the stop valve.

By the way, various types of preset devices are known, but a numeric keypad type is often used so that the amount or amount of refueling to be set can be freely and finely preset. Then, in order to perform setting operation using this numeric keypad type preset device, first operate the numeric keypad to input the numerical data corresponding to the preset value, and then operate either the refueling amount setting key or the refueling amount setting key. Type data is input.

For example, when setting 50 as the preset value, If you operate the key as and set 5000 yen, The key operation is as.

[Problems to be Solved by the Invention]

However, in the ten-key type preset device, the user may mistakenly operate the refueling amount setting key and the refueling amount setting key after inputting numerical data with the ten keys, and may refuel without noticing this.

In such a case, there is a problem that refueling is carried out in excess of the customer's ordered quantity, or refueling is completed with less than the ordered quantity. For this reason, if you refuel more than the former order quantity, you must be aware that the customer made a mistake in setting and must perform processing such as having you pay the amount equivalent to the actual refueling amount. There is a problem that it loses customer credibility and causes trouble. On the other hand, if the actual refueling amount is smaller than the latter order amount, it is necessary to end the refueling once and restart the preset refueling for the remaining amount, which is not only time-consuming, but also the slip is a double slip. Therefore, there is a problem that the customer is distrusted.

The present invention has been made in view of the problems of the related art as described above, and the set preset value specifies the amount of refueling or whether the amount of refueling is specified, the capacity of the fuel tank,
It is an object of the present invention to provide a refueling device that saves an erroneous operation by determining the authenticity according to the actual situation of a transaction.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a fixed pipe having one end connected to an oil storage tank, a pump and a flow meter provided in the middle of the fixed pipe, and a hose connected to the other end of the fixed pipe. , A refueling nozzle provided at the tip of the hose, a preset device that presets the amount of oil discharged from the refueling nozzle as a refueling amount or a refueling amount, and a refueling amount measured by the flow meter is a preset value by the preset device. In the oil supply device having a pump motor for driving the pump or an oil supply stop device including a stop valve provided in the middle of the fixed pipe, the oil supply should be stopped by the preset device as the oil supply amount. When the setting data is smaller than the predetermined upper limit value, the setting data is treated as it is as the refueling amount, and when it is larger, And oil supply amount setting authenticity determination means for handling the setting data as automatically fueling amount, when preset as oil amount by the preset device,
When the set data is larger than a predetermined lower limit value, it is treated as it is as a refueling amount, and when it is smaller, it is automatically treated as a refueling amount.

It is composed of a lower limit refueling amount storage area 26 for storing 100 yen / 1).

The present embodiment is configured in this way, and its operation will be described next.

First, the timing at which the presetting operation is performed by the presetting device 13 is to refuel in order to correct the preset value before removing the refueling nozzle 9 from the nozzle hook 10 (during the loop of step S1 in FIG. 5). In the middle (in the middle of the loop of steps S4 and S5 in FIG. 5),
After the customer stops ordering the pump motor 4 because the customer's order volume and the actual refueling volume are different (step S1 in FIG. 5).
2, S13 loop) is possible.

Therefore, FIG. 5 shows a processing operation in the case where the presetting is performed in any of the above three stages or the normal refueling is performed without presetting.

That is, in FIG. 5, step S1 is a waiting loop for removing the refueling nozzle 9 from the nozzle hook 10 and monitoring whether or not the nozzle switch 11 is turned on. When the nozzle switch 11 is turned on at step S1, the CPU 16 Based on the processing of step S2, the pump motor 4 is turned on in step S2 to start the pump 5, and in step S3, the oil supply amount indicator 12A of the indicator 12 is displayed.
Reset the refueling amount display 12B to zero.

Next, in step S4, whether the flow pulse is started to be input from the flow pulse generator 7 or in step S5, the nozzle switch 11 is started.
In the loop that monitors whether the is turned off, the refueling nozzle 9 is removed from the nozzle hook 10, but if it is re-applied to the nozzle hook 10 without actually refueling, then in steps S4 and S5, in step S9. Stop the pump motor 4, step S18
Return from. On the other hand, when the refueling nozzle 9 is inserted into the fuel tank and opened, the oil liquid in the underground tank is discharged from the refueling nozzle 9 through the fixed pipe 3, the pump 5, the flow meter 6, and the hose 8. As a result, the amount of refueling discharged by the flow meter 6 is measured, and at this time, the flow rate pulse transmitter 7 outputs a flow rate pulse corresponding to the measured flow rate to the control device 14, and the counting results are refueling amount and refueling amount, respectively. Display 12A, 12B
Is displayed on the screen (step S6).

In the next step S7, whether or not the measured refueling amount has reached the preset value P is determined in step S8 by closing the refueling nozzle 9 and applying it to the nozzle hook 10 so that the nozzle switch 11 operates.
In the loop for determining whether or not it is OFF, the fact that the nozzle switch 11 is OFF even though the amount of oil supply has not reached the preset value corresponds to the case of normal oil supply, so the pump motor 4 is turned OFF in step S9. After that, the process returns from step S18.

On the other hand, the fact that the refueling amount and the preset value P match in step S7 means that the oil supply amount and the preset value P match in step S1 or
Since the presetting operation is performed by the presetting device 13 in the middle of the loop of 5, and the amount of refueling has reached the fixed value, the pump motor 4 is turned off and the preset refueling end flag is turned on in the next step S10. Then, in the next step S12, it is determined whether or not the refueling instruction flag is ON, and if it is OFF, it is not necessary to refuel, so the preset refueling work is completed, and in step S13 the nozzle switch When it is confirmed that 11 has been turned off, in the next step S14, the data in the setting data storage area 20 and the preset value storage area 21 in the RAM 18 are cleared in preparation for the next preset lubrication, and in the next refueling in step S15. OFF the preset refueling end flag and refueling instruction flag for
After that, the process returns from step S18. In step S14, when the preset value storage area 21 is cleared, the preset value P is cleared to the maximum value indicating fullness.

Further, when it is determined that the refueling instruction flag is ON in step S12, the refueling instruction flag is set to ON in the loop of steps SP11 and SP12 in the process of FIG. 6 described later. Here, the refueling instruction flag indicates that the amount of fuel supplied at the end of the preset refueling in step S11 is insufficient with respect to the customer's order amount, and in order to continue the represet refueling, the refueling instruction flag is set between the loops of steps S12 and S13. , Is turned on when the preset value corrected by the presetting device 13 is reset.

Therefore, in this case, the process proceeds from step S12 to S13, the pump motor 4 is turned on again, the oil liquid is discharged from the oil supply nozzle 9, and then the preset refueling end flag and the refueling instruction flag are turned off in the next step S17. Then, the process proceeds to step S4 and the same process as described above is repeated to carry out the fixed amount refueling for the re-preset value, and the process goes to step S18 through the loop of steps S7 to S10 to S15 to finish the preset refueling for the ordered amount.

Now, the above description is the operation of the fixed weighing machine 1 side with respect to the preset refueling and the normal refueling. Next, regarding the authenticity determination of the preset setting data by the presetting device 13, referring to the preset setting processing of FIG. Describe.

Now, it is assumed that the preset device 13 is operated, the numerical data A is set by the ten keys 13A, and the type data B is set by the refueling amount setting key 13B or the refueling amount setting key 13C.

Then, in step SP1 in FIG. 6, the setting data consisting of the numerical data A and the type data B is taken into the setting data storage area 20 in the RAM 18. And the next step
In SP2, it is determined whether or not the type data B is monetary data, and if it is monetary data, the process proceeds to step SP3, in which the numerical data A as the refueling amount is divided by the unit price to be converted into the refueling amount, and the converted value. Is calculated as (A / unit price). Then, in the next step SP4, it is determined whether or not the converted value is larger than the lower limit oil supply amount by referring to the lower limit oil supply amount stored in the lower limit oil supply amount storage area 25 in the RAM 18. Here, the lower limit refueling amount is, as described above, the lower limit refueling amount such that gasoline will not be ordered at a refueling amount lower than this, for example, a conversion value equivalent to 100 yen. 1
Is represented.

Therefore, when it is determined to be "YES" in step SP4, since it is larger than the lower limit refueling amount 1, it is assumed that the numerical data A and the type data B are correctly operated.
In SP5, the converted value (A / unit price) is set as the preset value P in the preset value storage area 21 of the RAM 18. On the other hand, when it is determined to be “NO” in step SP4, the conversion value (A / unit price) is, for example, 0.4, and the preset value 13 is originally set. And where to operate, It is highly possible that you operated. Therefore, in this case, the process proceeds to step SP6 and the numerical data A is regarded as an input error of the refueling amount data, and the numerical data A is stored in the preset value storage area 21 as the preset value P as it is.

When it is determined in step SP2 that the type data B is the refueling amount data, the process proceeds to step SP7, and it is determined whether or not the numerical data A is smaller than the upper limit refueling amount stored in the upper limit refueling amount storage area 25 in the RAM 18. Determine whether. Here, as described above, the upper limit refueling amount represents the upper limit refueling amount assumed from the capacity of the fuel tank, for example, 150.

Therefore, when it is determined to be "YES" in step SP7, it is smaller than the upper limit refueling amount, so that it is assumed that the numerical data A and the type data B are correctly operated in step SP8.
Then, the numerical data A is set as the preset value P in the preset value storage area 21. On the other hand, in step SP7, "N
When it is determined to be “O”, the numerical data A is larger than 150, and the preset device 13 originally And where to operate, There is a strong possibility that you have operated. Therefore, in this case, the process proceeds to step SP6 to calculate the amount of refueling from the converted value (A / unit price), and the converted value (A / unit price) is set in the preset value storage area 21 as the preset value P in step SP10.

Further, when the setting process of steps SP5, SP6, SP8, SP10 is completed, it is determined in step SP11 whether the preset refueling flag is ON. Here, the fact that the preset refueling end flag is ON means that the pump motor 4 is turned off and the preset refueling is completed, as is clear from steps S10 and S11 in FIG. Therefore, NO in step SP11
If it is determined that the preset device 13 has been operated before the end of the preset refueling (specifically,
There is no need for additional refueling, and the process returns from step SP13, in the loop of step S1 or steps S4 and S5 in FIG. On the other hand, when it is determined to be "YES" in step SP11, after the preset refueling is finished, the preset value P is set to be smaller than the customer's order quantity and reach the customer's order quantity. It is probable that the preset operation was performed again during the loop consisting of S12 and S13. Therefore, in this case, steps SP11 to SP
Go to 12 and set the refueling instruction flag to ON, then step SP
Return from 13.

As described above, according to the present embodiment, when the preset amount of oil or the amount of oil supplied is preset by the presetting device 13, even if an erroneous operation is performed for some reason, the upper limit and the lower limit of the amount of oil supply and the lower limit for the numerical data A and the type data B are set. Whether the setting operation is true or false can be judged from the refueling amount, and if there is an error in the setting, it can be automatically preset as the correct refueling amount or refueling amount, leading to customer distrust and unnecessary troubles. It can prevent the situation.

In the embodiment, steps SP2 to SP6 in FIG. 6 are specific examples of the refueling amount setting authenticity determining means according to the present invention, and steps SP2, SP7 to SP10 are specific examples of the refueling amount setting authenticity determining means. However, the present invention is not limited to this specific example.

Further, in the embodiment, the pump motor 4 that starts and stops the pump 5 is illustrated as the oil supply stop device at the time of preset oil supply, but as shown by the alternate long and short dash line in FIG. A configuration may be adopted in which the stop valve 27 formed of a solenoid valve is provided and the stop valve 27 is quantitatively stopped by the valve closing signal output from the control device 14 when the amount of oil supply reaches the preset value P. In this case, step S1 in FIG.
"Pump motor ON, stop valve open", Step S9 "Pump motor OFF, stop valve close", Step S10 "Stop valve close",
The step S16 may be "open stop valve".

On the other hand, in the embodiment, the fixed weighing machine 1 is illustrated as the refueling device, but it may be a suspended weighing machine in which the refueling nozzle is suspended from the height of the gas station so that it can be moved up and down.

Further, the presetting device 13 is a casing 2 of the weighing machine 1.
It is not limited to the one provided inside, but may be provided on the side wall of the gas station building, the office room, or the like, or may be a preset device using a sales management machine (POS).

The refueling device according to the present invention is as described above in detail, and when presetting the refueling amount and refueling amount by the presetting device, various operations such as erroneous operation of the numeric keypad, chattering, refueling amount designation key, erroneous operation of refueling amount designation key, etc. Even if the customer sets the data different from the customer's order amount due to the cause, the refueling amount authenticity determining means and the refueling amount authenticity determining means can automatically set the preset value as it should be. It eliminates the problem of refueling more than the ordered amount or stopping quantitatively when the amount is less than the ordered amount, preventing distrust of customers and preventing troubles with customers. Can be done.
