Description

DETAILED DESCRIPTION OF THE INVENTION The present application relates to a refueling system for refueling an automobile with an oil liquid such as gasoline at a refueling station.

In recent years, in order to improve work efficiency, devices with a so-called preset function have become popular at gas stations, allowing users to set the desired amount and amount of refueling in advance, and automatically stop refueling when the refueling amount exceeds the set amount or amount. I've been doing it. When using such a device to refuel a customer who pays in cash, when the customer specifies the amount of refueling, he or she never specifies a fraction to the 10 yen or 1 yen digit, but the customer specifies the amount of refueling. In this case, depending on the unit price, fractions are often generated in the 10 yen or 1 yen digits, and in particular, amounts in the 1 yen digit are often rounded down as services. If the cost of this service increases, the amount will be enormous, resulting in a large loss for the filling station.

This application is proposed in view of the above problem, and when the amount of refueling is specified and set, the amount of refueling is calculated, and if there is a fraction in the calculated value, it is first calculated so that it becomes the nearest amount without the fraction. A set oil supply amount is changed, and an illustrated example will be described below.

In Figure 1, (1) is an island installed on a dirt floor G, with pillars (3) (4) (5) (

Next, as explained based on FIG. 2, nozzle (8) <sr
Since this is a joint composition of two systems involved, only one system will be explained.

In (a), the flowmeter (not shown) is a unit flow rate (here 1/
10001) is a pulse transmitter that outputs one pulse P each time it is measured, (a) is a counting circuit that counts pulses P and outputs the counted value as a refueling amount signal d, and (goods) is a unit price set. The unit price setter displays the unit price on the display 04) by continuously outputting the unit price signal a.
A unit amount output circuit that outputs an amount signal m corresponding to 21 pulses every time one is input; (a) a counting circuit that counts the signal m and outputs the counted value as a refueling amount signal n;
A is a preset value setting key, 2) is a setting circuit that memorizes and retains the set value when the refueling amount is set in setting key A, and outputs a set amount signal, and 2) is the output signal of the counting circuit (C). A comparison circuit that compares n and the output signal S of the setting circuit @, and when they match, outputs a signal S and gives it to the motor control circuit. This is a setting circuit that stores and holds a set amount signal C and outputs a set amount signal C.

Kl is 1 if you want to eliminate fractions less than 10 yen.
This key is used when you want to zero the digit of the yen.
When K2 is operated, signal r1 is output, and K2 is also used when you want to eliminate fractions less than 100 yen, that is, 10.
This key is operated when you want to set the digit of yen or 1 yen to zero, and when the key is operated with 2, a signal r2 is output.

OD is a correction circuit, and the signal r1. When neither r2 is input, the signal C is passed through as is and the comparison circuit (to)
is sent to the display output, but when the signal rz or signal r2 is input, the signal C (i.e., the set amount) is divided by the signal a (i.e., the unit price), and if there is a fraction in the calculated value, the fraction near the calculated value Correct and change the set oil supply amount to a value without
The corrected setting oil supply amount is given to the comparison circuit display Q. The comparison circuit (2) compares the set oil supply amount or the changed set oil supply amount with the signal d, and outputs the signal S when the two match.

SWl is a switch that is installed in connection with the case NC1 and outputs a signal t when the nozzle (8) is stored in the case NC1.SW2 is a switch that is installed in connection with the case NC2 and outputs a signal t when the nozzle (8) is stored in the case NC1.
This is a switch that outputs a signal t' when the nozzle (8) is retracted to the case NC1, and the motor control circuit is a switch that outputs a signal t' when the nozzle (8) is retracted to the case NC1.
, NC2, the motor M of the pump (not shown) is energized.

Here, for one nozzle (8), the nozzle case NC
1 and NC2 are provided because the hose (9) travels a long distance, so it can be returned to either nozzle case.

In the above arrangement, on the premise that the unit price set in the unit price setter (c) is 157 yen, a case will first be described in which the customer specifies an amount, for example, requests for refueling for 3,500 yen.

The worker first keys in a setting key worth 3,500 yen.

Then, the value of 3,500 yen is stored and held in the setting circuit (), and that value is given as a set amount signal to the comparison circuit (c) and the display αη, and the display Qη displays 3500 yen as a preset value. Ru.

Next, when the nozzle (8) t'' is removed from the case NC□ or NC2, the output signal t from both switches sw1 and sw2.

In the absence of t', the following operations are performed in response to this.

■The control circuit energizes the motor M and pumps (path shown)
Rotate.

- The counting circuits (c) and (e) return to zero, and the display α 03 displays zero.

After that, when the nozzle (8) is operated to start refueling, a pulse P is output from the transmitter (a) linked to the flow meter (indicated path), and the counting circuit (2) counts this pulse P and calculates the value. The numerical value is displayed on the display (2) as the amount of oil to be supplied.At this time, every time a pulse P is input from the unit amount output circuit (c), a signal m [in this case 157 yen XI/1000 (a=0
．． 157 yen] is output, the counting circuit (c) counts this signal m and displays the counted value as the refueling amount on the display (to).
to be displayed.

When the refueling work progresses and the count value of the counting circuit (c) matches the set amount (3,500 yen) that was previously input to the comparator circuit (c), the comparator circuit (c) outputs a signal S to control the control circuit (c). b) and de-energizes the motor M, thereby stopping the pump and completing the refueling. After that, when the nozzle (8) is returned to the case NC1, Nc2, the switch 8W1
, SW2 or the signal t' is output, and the following operation is thereby performed.

■If the motor M is still energized at this point (at the time of full lubrication, not preset lubrication), de-energize the motor M.

■Reset the setting circuit @ (to) and prepare for the next preset lubrication.

■Reset the correction circuit 0υ.

(2) Reset the comparator circuit (if the preset oiling signal S or signal S' is being output, it will disappear by this reset).

After this, the customer pays 3,500 yen in cash and leaves.

Next, a case will be explained in which the customer requests refueling for a specified amount, for example, 18A, but the explanation of the part where the same operation as the previous amount specification is performed will be omitted this time.

The operator first keys in 181 to setting key A. Then, the value 11' is stored and held in the setting circuit (to), and the value is given to the correction circuit 6υ as the setting signal C, but at this time, the signal C passes through the correction circuit 0υ and is sent to the comparison circuit. ) and to the display αη, and to the display Q′7) is 1
8/ is displayed as the preset value.

If refueling is carried out under this condition, the customer will receive 18
(You will be charged axxs7 yen = 2826 yen,
Here, in order to make the 1 yen digit zero, 1 is operated on the key and the signal r1 is given to the correction circuit 0◇.The correction circuit c1η rounds off the 1 yen digit to make it zero. Then, the value of 18.0251 [-2830 yen ÷ 157 yen (unit price)] is given to the comparator circuit (To) and display Q7) as a corrected setting amount, and the display 0η shows a value of 18.0251 [-2830 yen ÷ 157 yen (unit price)]. Te 18.0251! is displayed. After that, refueling is carried out, and the counted value of the counting circuit (E), that is, the refueling amount and the corrected setting amount (if they match, it is sent to the comparator circuit), outputs a signal S' and gives it to the control circuit.
deactivate.

At this time, the refueling amount displayed on the display q■ is 283° yen.

Next, to explain the case where the key is operated to set 2 to 10 yen instead of 1 and the 1 yen digit to zero, and the signal r2 is given to the correction circuit 0◇, the refueling amount corresponding to the set amount 181 Round off the 10 yen digit of 2826 yen to 2800.
yen, and further 2800 yen ÷ 157 yen = 17.534 (
A') is given to the comparator circuit as a correction setting amount) and to the display αη.

Here, it was written so that the 1 yen digit or the 10 yen digit is rounded off by the signal rl or signal r2, but it is also possible to always round down or round up, or to perform calculations such as rounding to the nearest whole number or six places. 1 for the key
．． 2 may be configured so that the signal r1 or signal r2 can be continuously outputted without having to be operated for each refueling.

Further, the preset amount may be displayed together with the set amount, the corrected set amount, and the refueling amount for the setting i' or the corrected set amount.

With the configuration as described in detail above, by adopting the present invention, even if the customer specifies the amount of refueling, it is possible to refill the amount of oil without a fraction, so there is no need to service a fraction of the amount, resulting in no loss to the filling station. will be completely eliminated.

Claims (1)

[Claims] In a device that has a preset function that automatically stops refueling when a preset amount of refueling is completed, the refueling amount is calculated by calculating between the preset amount and the unit price of oil. If the calculated value has a fraction, the preset oil supply system is configured to change the set amount to a value close to the calculated value without a fraction.
