Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling system for supplying oil such as gasoline at a refueling station.

Recently, an increasing number of gas stations are issuing cards that identify the owner not only to credit customers, but also to cash customers, and offering some kind of benefits to attract customers.

On the other hand, as required by the Measurement Act, refueling devices display the amount of refueling down to 1/100 and the amount of refueling up to the 1 yen digit, but POS terminals record and aggregate the amount of refueling for each customer. Currently, aircraft record only up to 1/10th, and the 1/100th place is rounded down, and when this rounded-off amount is added up, the loss to the filling station becomes enormous.

Therefore, as shown in Japanese Patent Publication No. 51-27833, after a stop warning operation such as pressing a switch or operating a nozzle to change the flow velocity according to a certain rule, the amount of refueling or the amount of refueling without a fraction is calculated. Refueling devices that are equipped with a means to automatically stop refueling when the fuel runs out have begun to be used. However, even if there is no fraction in the amount of refueling, there may be a fraction in the refueling amount depending on the unit price, and there are few places that charge cash customers in the 1 yen digit, and it is common to make it a service. If the amount for this service is added up, it will add up to a huge amount, so if you are a cash customer, refueling will be stopped at a fractional amount, whereas if you are a credit card customer, your refueling will be stopped without a fractional amount. It was necessary to ask the customer in advance and manually switch the refueling stop so that the refueling would be stopped according to the amount, but inexperienced workers (part-time workers, etc.) often forgot to do this.

The present invention is proposed in view of the above-mentioned problems, and if the card brought by the customer is for a credit card customer, an automatic stop is performed for the amount of refueling, and if the card is for a cash customer, the amount of refueling is automatically stopped. The above-mentioned problem is solved by automatically stopping the oil, and its configuration includes a transmitter that outputs a number of flow pulses corresponding to the measured amount of oil, and a transmitter that counts the flow pulses. a first counting circuit that calculates the amount of refueling; a second counting circuit that calculates the amount of refueling from the amount per unit amount of oil based on the unit price and the amount of oil;
A determination circuit that outputs a stop signal when a stop warning operation is performed, a reader that reads information from a specific piece owned by the customer and storing information specifying whether the customer is a credit customer or a cash customer; A memory circuit that stores information and outputs an amount stop signal or an amount stop signal, monitors the amount of refueling, and stops refueling at the exact value without fractions by inputting the amount stop signal and the exactly stop signal. An amount exactly stop circuit that outputs a refueling stop signal to make the refueling amount stop, and a refueling stop signal that monitors the refueling amount and stops refueling at the exact value without fractions by inputting the amount stop signal and the exactly stop signal. It is equipped with a stop circuit for just the amount of money. The illustrated embodiment will be described below.

First of all, based on Figures 1 and 2, 1 is a refueling device, and on the front there is a refueling amount display 2, refueling amount display 3, and unit price display 4, and on the side, a refueling hose 5 and a refueling nozzle 6 are attached to the nozzle case. It is deployed in a state where it is stored in 7. 8 is a box containing a card reader 9 and a change switch 10, which will be described later.

When a card owned by a customer is read by a card reader 9 before refueling, the reader 9 determines whether the customer is a credit customer, that is, the quantity is stopped, or whether the customer is a cash customer, that is, the amount is stopped, and stores this in the storage circuit 11. At the same time, if it is a credit card customer, a volume stop signal a is output and display 1 is displayed.
2 lights up to notify that the automatic stop for the amount has been specified, and the amount exactly stop circuit 13
On the other hand, if the customer is a cash customer, an amount stop signal b is outputted, a display 14 is turned on to notify that automatic stop for the amount has been specified, and an instruction is given to the amount exact circuit 15.

At this time, by pressing the change switch 10, a signal c (one pulse) is output, and the metal stop and the quantity stop can be changed to each other.

Next, when the nozzle 6 is removed from the nozzle case 7, the output signal n of the nozzle detection switch 16 changes from L (low level) to H (high level). The count values of the first counting circuit 17 and the second counting circuit 18 return to zero, the displays 3 and 2 display zero, and the motor control circuit 19 starts the motor 20 to drive the pump (not shown). energize.

When the nozzle is inserted into the car's fuel filler port (not shown) and refueling begins, the oil sent from the pump is guided to the hose 5 through a flow meter (not shown) and is discharged from the nozzle 6, but the flow rate is low. The gauge is the unit oil amount (1/1000
) is sent from the transmitter 21 every time a flow rate pulse d is measured.
are output one by one, and the counting circuit 17 receives this pulse d.
is counted, and the counted value is displayed numerically on the display 3 as the amount of oil to be supplied.

Every time one pulse d is input, the calculation circuit 22 outputs an amount signal corresponding to one pulse d to the counting circuit 18 based on the unit price set by the unit price setting circuit 23, and the counting circuit 18 receives this signal. It is counted and the counted value is numerically displayed on the display 2 as the refueling amount.
Note that the display 4 displays the unit price set in the unit price setting circuit 23.

As the refueling operation progresses and the fuel tank is filled without automatic stop based on the amount or amount, when the nozzle 6 is returned to the case 7, the signal n changes from H to L, and the motor 20 At the same time, the memory contents of the memory circuit 11 are reset to prepare for the next refueling.

However, when the refueling flow rate is changed according to a predetermined "rule" by operating the lever 6' of the nozzle 6, the determination circuit 23 takes this as a stop warning operation, and when the stop signal e
(one pulse) is output. In the case of a credit customer, the signal a has been output from the memory circuit 11 first, so the quantity exactly stop circuit 13 starts operating in the presence of the signals e and a, and the count value of the counting circuit 17 is a fraction. When a digit without a digit, such as 1/10 or 1/100, becomes zero, a refueling stop signal f is output and applied to the motor control circuit 19 to de-energize the motor and stop refueling. On the other hand, if you are a cash customer, signal B first.
is being output, so the amount exactly stop circuit 15 starts operating due to the presence of signals e and b, and the count value of the counting circuit 18 is a value without a fraction, for example, 10 yen, and the digit of 1 yen becomes zero. A time signal g is outputted and applied to the motor control circuit 19 to de-energize the motor and stop refueling.

Note that the content stored on the card is not only the data of credit customers and cash customers, but also the data for distinguishing between four-wheeled vehicles and two-wheeled vehicles. Alternatively, stops are made in 100 yen increments, and for vehicles with small fuel tanks such as motorcycles, stops are made in 1/10 or 10 yen increments, and for walk-in passengers who do not have a card. When the change switch 10 is pressed once, the amount is set to stop, and when the change switch 10 is pressed once again, the amount is set to stop.

Since each oil supply device can be controlled by 2' and 14', an inexpensive system can be obtained. In addition, when adopting this system, the card is read to confirm whether the quantity or amount is to be stopped, and the designated switch 36 is operated to designate the refueling device. It will no longer be possible to change.

By configuring the system as described in detail above, automatic suspension methods are provided according to the type of customer, allowing for accurate transactions without the need to round down small charges or perform extra services. be.
