In the latter means, when the oil-feeding price is preset by the preset device 13, the set data is dealed with as the oil-feeding price as it is in such a case that the set data is larger than a predetermined lower limit value and automatically dealed with as the oil-feeding amount in such a case that said set data is larger than said lower limit value.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a refueling device for refueling a fuel tank of a vehicle with an oil liquid such as gasoline. The present invention relates to a refueling device having a preset refueling function that performs fixed refueling according to the set amount.

[Conventional technology]

Generally, in order to perform refueling work using a refueling device equipped with a preset refueling function, the customer's desired amount of refueling or amount of refueling is set in advance by the presetting device prior to refueling, and then the refueling nozzle is inserted into the fuel tank. By inserting the oil in the tank and opening the valve, the oil in the oil storage tank is discharged from the oil supply nozzle via the pump, flow meter, and hose, and the pump motor automatically stops when the actual oil supply amount matches the preset value. When the stop valve closes automatically, fixed amount refueling is carried out.

By the way, various types of presetting devices are known, but ten-key type devices are often used so that the amount of refueling or amount of refueling to be set can be freely and precisely preset. To perform settings using this numeric keypad preset device, first operate the numeric keypad to input numerical data corresponding to the preset value, and then operate either the refueling amount setting key or the refueling amount setting key. Type data can be entered using

For example, when setting 50 sentences as a preset value, the key operation is performed as (5) Doguchi, and when setting 5000 yen, the key operation is performed as Rororo n country.

[Problem to be solved by the invention]

However, with the numeric keypad presetting device, after inputting numerical data using the numeric keypad, it is possible to accidentally operate the refueling amount setting key and the refueling amount setting key, and refueling without realizing it. .

In such a case, there is a problem that refueling is performed in an amount larger than the amount ordered by the customer, or refueling ends with an amount of refueling less than the amount ordered. Therefore, if you refuel more than the amount ordered by the former, you must apologize to the customer for the setting error and ask them to pay the amount equivalent to the actual amount of refueling. This has the problem of losing customer trust and causing trouble. On the other hand, if the actual amount of refueling is less than the latter ordered amount, it is necessary to end refueling and then restart preset refueling for the remaining amount, which is not only time-consuming but also creates duplicate documents. There is a problem that it becomes a slip and causes distrust among customers.

The present invention was developed in view of the problems of the prior art, and it is possible to determine whether the set preset value specifies the amount of refueling or the amount of refueling, depending on the capacity of the fuel tank and the actual situation of the transaction. It is also an object of the present invention to provide a refueling device that can relieve erroneous operation by determining authenticity.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a fixed pipe whose one end is 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 presetting device that presets the amount of oil discharged from the refueling nozzle as a refueling amount or refueling amount, and a preset value of the refueling amount measured by the flowmeter by the presetting device. In order to stop the refueling when the preset device reaches the preset amount, the refueling device is equipped with a refueling stop device consisting of a pump motor that drives the pump or a stop valve installed in the middle of the fixed piping, in order to stop the refueling when the amount reaches the preset amount. If the setting data is smaller than a predetermined upper limit value, the setting data is treated as the refueling amount as is, and if it is larger than the specified upper limit value, the setting data is automatically treated as the refueling amount. and when preset as the refueling amount by the preset device,
The present invention is characterized by comprising a refueling amount setting truth/falsity determining means which directly handles the setting data as the refueling amount when it is larger than a predetermined lower limit value, and automatically handles it as the refueling amount when it is smaller.

[Effect]

By configuring in this way, among the setting data by the preset device, based on the size of the setting numerical value of the numerical data and the setting type such as whether the type data is the amount of refueling or the amount of refueling,
The refueling amount setting authenticity determination means and the refueling amount setting authenticity determination means determine whether it is the refueling amount or refueling amount from the upper and lower limits, respectively, depending on the actual circumstances of the transaction, and even if there is an incorrect setting, it is determined that the refueling amount is correct. The refueling operation is performed according to a type that can be determined.

A refueling amount setting key 13C for specifying the refueling amount, an upper limit setting key 13D for specifying the upper limit, which will be described later, a lower limit setting key 13E for specifying the lower limit, and a function key 13F for specifying unit price and other information. It is composed of:

Further, reference numeral 14 indicates a control device provided in the housing 2, and as shown in FIG. To store the programs shown in FIGS. 5 and 6, a program memory 17 consisting of RoMg (hereinafter referred to as FROMl 7J),
It is constituted by a microcomputer consisting of a data memory 18 such as a RAM (hereinafter referred to as rRAM 18J) that includes each area shown in the figure. The input side of the control device 14 is connected to the flow rate pulse generator 7, the nozzle switch 11, and the preset device 13, and the output side is connected to the display 12 and a pump motor drive circuit 19 for starting and stopping the pump motor 4. ing.

It has the function of

Furthermore, FIG. 4 is an explanatory diagram showing the basic structure of the RAM 18, which includes a setting data storage area 20 for storing setting data consisting of numerical data A and type data B preset by the presetting device 13. , 6th

A refueling instruction flag area 23 that stores a refueling instruction flag that becomes ON only when the preset device 13 is operated and new setting data is input while the flag is ON, and a unit price that stores the unit price of fuel. When setting the refueling amount using the storage area 24 and the preset device 13, the upper limit refueling amount storage area 25 stores the upper limit refueling amount (for example, 1501) assumed based on the capacity of the fuel tank, and the presetting device 13 stores the refueling amount. When setting, the lower limit oil supply amount storage area 26 stores the lower limit oil supply amount (for example, 1 sentence if the unit price is 100 yen/month) corresponding to the lower limit amount (for example, 100 yen) assumed from the actual situation of the transaction. It is configured.

The present embodiment is configured as described above, and its operation will be described next.

First, the timing at which the presetting device 13 performs the presetting operation is such that the refueling nozzle 9 is connected to the nozzle hook 10.
(during the loop of step S1 in Figure 5), while refueling to correct the preset value (during the loop of steps S4 and S5 in Figure 5), the customer's order amount This may occur after the pump motor 4 is stopped for a fixed amount (loop of steps S12 and S13 in FIG. 5) because the actual amount of oil supplied differs from the amount of oil supplied.

Therefore, FIG. 5 shows processing operations when presetting is performed in any of the above three stages, or when refueling is performed as normal refueling 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 in Step 1, the pump motor 4 is turned ON in step S2 based on the processing of the CPU 16, and the pump 5 is started. Reset to zero.

Next, step S4 is a loop that monitors whether input of the Ii heat pulse from the flow rate pulse generator 7 has started, and step S5 is a loop that monitors whether the nozzle switch 11 has been turned OFF, and the refueling nozzle 9 is removed from the nozzle hook 10. If the nozzle hook 10 is hooked again without actually refueling, step S4. After passing through S5, the pump motor 4 is stopped in step S9, and the process returns from step 318. On the other hand, when the refueling nozzle 9 is inserted into the fuel tank and the valve is opened, the oil in the underground tank flows through the fixed pipe 3, the pump 5, the flow meter 6, and the hose 8.
The oil is discharged from the oil supply nozzle 9 through the oil supply nozzle 9. As a result, the amount of oil dispensed is measured by the flow meter 6, and at this time, a flow pulse corresponding to the measured flow rate is output from the flow rate pulse transmitter 7 to the control device 14, and the counting results are used as the amount of oil to be refilled and the amount of refueling. are displayed on the displays 12A and 12B, respectively (step S
6).

In the next step S7, it is determined whether the measured oil supply amount has reached the preset value P, and in step S8, it is determined whether the nozzle switch 11 has been turned OFF by closing the oil supply nozzle 9 and applying the nozzle hook 10. In the determination loop, if the nozzle switch 11 is turned off even though the amount of oil supply has not reached the preset value, this corresponds to normal oil supply, so after turning off the pump motor 4 in step S9, the process is performed in step S518. Return from.

On the other hand, the fact that the refueling amount and the preset value P match in step S7 means that
4. During the loop of S5, the preset device 13 performs a preset operation, and the amount of oil supplied reaches the fixed value, so in the next step S10, the pump motor 4 is turned off.
FF and turn on the preset refueling end flag. Then, in the next step S12, the refueling instruction flag is turned ON.
If it is OFF, there is no need to re-lubricate, so after the preset lubrication work is completed and it is confirmed that the nozzle switch 11 is OFF in step S13, the next In step S14, data in the setting data storage area 20 and preset value storage area 21 in the RAM 1B are cleared in preparation for the next preset lubrication, and in step S15, the preset lubrication end flag and refueling instruction flag are set for the next lubrication. After turning off, the process returns from step 318. In step S14, when the preset value storage area 21 is cleared, the preset value P is cleared to the maximum value indicating a full tank.

Further, when it is determined in step S12 that the refueling instruction flag is ON, the refueling instruction flag is set to ON in the loop of steps 5PII and 5P12 in the process shown in FIG. 6, which will be described later. Here, the refueling instruction flag indicates that the amount of refueling at the end of the preset refueling in step 311 is insufficient with respect to the customer's order amount, and in order to continue the preset refueling, the refueling instruction flag is set in steps S12 and S13.
During the loop consisting of the following, when the corrected preset value is reset by the preset device 13, the switch is turned ON.

Therefore, in this case, the process proceeds from step S12 to 513, where the pump motor 4 is turned ON again and the oil is discharged from the oil supply nozzle 9, and then, at the next step S17, the preset oil supply end flag and the refueling instruction flag are turned OFF. , Ste.
The process moves to step S4, repeats the same process as described above, performs fixed amount lubrication according to the preset value again, and moves from step S7 to step S5.
Step 318 is reached through a loop of steps 10-15, and the preset oil supply for order b2 is ended.

Now, the above explanation is about the operation of the fixed weighing machine 1 for preset lubrication and normal lubrication.Next, regarding the authenticity determination of the preset setting data by the preset device 13,
This will be described with reference to the preset setting process shown in FIG.

It is now assumed that the precent device 13 is operated, numerical data A is set using the numeric keypad 13A, and type data B is set using the refueling amount setting key 13B or refueling amount setting key 13G.

Then, in step SPl in FIG. 6, the setting data consisting of the numerical data A and type data B is loaded into the setting data storage area 20 in the RAM 1B. Then, in the next step SP2, it is determined whether or not the type data B is monetary data. If it is monetary data, the process proceeds to step SP3, and the numerical data A representing the refueling amount is divided by the unit price to obtain the refueling amount. Convert and find the converted value as (A/unit price).

Then, in the next step SP4, the lower limit oil supply amount stored in the lower limit oil supply amount storage area 25 in the RAM 18 is referred to, and it is determined whether the converted value is larger than the lower limit oil supply amount. Here, the lower limit refueling amount is, as mentioned earlier, the lower limit amount under which an order for gasoline, etc. will not be made considering the actual transaction situation, for example, 100 yen.
It represents one sentence of conversion value equivalent to yen.

Therefore, when it is determined as "YES" in step SP4, since the lower limit oil supply amount is greater than one sentence, it is assumed that numerical data A and type data B have been operated correctly, and the process proceeds to step SP5, where the preset value is stored in the RAM 18. A converted value (A/unit price) is set in area 21 as a preset value P. - On the other hand, when it is determined "NO" in step SP4, the converted value (A/unit price) is, for example, 0.4 sentences, and it is possible that the preset device 13 was operated in a slow manner, when it should have been operated slowly. strong. Therefore, in this case, the process moves to step SP6, where the numerical data A is regarded as an input error in the oil supply amount data, and the numerical data A is stored as the preset value P in the preset value storage area 21 as it is.

Further, when it is determined in step SP2 that the type data B is oil supply amount data, the process proceeds to step SP7 to determine whether the numerical data A is smaller than the upper limit oil supply amount stored in the upper limit oil supply amount storage area 25 in the RAM 18. Determine whether Here, the upper limit refueling amount represents the upper limit refueling amount that can be assumed based on the capacity of the fuel tank, for example, 150 liters, as described above.

Therefore, when rYESJ is determined in step SP7, it is smaller than the upper limit oil supply amount, so it is assumed that numerical data A and type data B have been operated correctly, and the process proceeds to step SP8, where numerical data A is preset as preset value P. Set in value storage area 21. On the other hand, when it is determined as rNOJ in step SP7, the numerical data A is more dog than 150, and the preset device 13 should normally operate, for example, DID RORO, Q[C]l.
There is a strong possibility that it was operated as Io[E]E]. Therefore, in this case, the process moves to step SP9 to calculate the oil supply amount from the converted value (A/unit price), and sets the converted value (A/unit price) as a preset value P in the preset value storage area 21 in step 5PIO.

Furthermore, step SP5, SF3, SF3.

When the 5PIO setting process is completed, it is determined in step 5PII whether or not the preset oil supply flag is ON. here,
The fact that the preset oil supply end flag is ON indicates that the pump motor 4 is at 0FFL and the preset oil supply has been completed, as is clear from step S10°Sll in FIG. Therefore, when the determination in step SPI 1 is NO, it means that the preset device 13 was operated before the end of preset oil supply (specifically,
Step S1 or step S4 in FIG. During the loop of S5), there is no need for additional refueling, and step 5P1
Return from 3. −, rY at step SPI 1
When it is determined that EsJ is the case, after the preset oil supply is completed -1, the preset value P is smaller than the customer's order amount and is set to reach the customer's order amount in step S12. It is considered that the preset operation was performed again during the loop consisting of S13.

Therefore, in this case, proceed from step 5PII to 5P12, turn on the refueling instruction flag, and then proceed to step 5P
Return from 13.

As described above, according to the present embodiment, when the preset device 13 performs a preset operation on the refueling amount or refueling amount, even if there is an erroneous operation for some reason, the numerical data A and the type data B are set to the L limit refueling amount. It is possible to determine the authenticity of the setting operation based on the lower limit oil supply amount, and if there is an error in the setting, it can be automatically preset as the correct oil supply amount or amount, which may lead to customer distrust or unnecessary trouble. It is possible to prevent such situations from occurring.

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

In addition, in the embodiment, the pump motor 4 that starts and stops the pump 5 is used as the lubrication stop device during preset lubrication, but as shown by the dashed line in FIG. A stop valve 27 made of a solenoid valve may be provided, and when the amount of oil supplied reaches a preset value P, a valve closing signal output from the control device 14 may be used to stop the stop valve 27 at a fixed amount. In this case, step S1 in FIG.
9 to "Pump motor OFF, stop valve closed", Step 31
0 may be set as "stop valve closed" and step S16 may be set as "stop valve open".

On the other hand, in the embodiment, a fixed weighing machine 1 is used as an example of the fueling device, but a suspended weighing device in which the fueling nozzle is suspended from a high place at a fueling station so as to be movable up and down may be used.

Furthermore, the presetting device 13 is arranged in the casing 2 of the weighing machine l.
The presetting device is not limited to being installed inside the building, but may be installed on the side wall of a gas station building, inside an office, etc., or may be a presetting device using a sales management machine (PO3).

〔Effect of the invention〕

The refueling device according to the present invention is as described in detail above, and when presetting the refueling amount and refueling amount using the presetting device, there are various problems such as erroneous operation or chuckling of the numeric keypad, erroneous operation of the refueling amount designation key, the refueling amount designation key, etc. Even if data is set that differs from the customer's order amount due to a reason, the refueling amount authenticity determination means and the refueling amount authenticity determination means can automatically set the data as the original preset value. Reliable preset lubrication eliminates the problem of refueling more than the ordered amount or stopping at a fixed amount when less than the ordered amount, and prevents situations that may cause customer distrust or trouble with customers. can be done.
