Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling system for supplying oil such as Karin 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 special bonus to attract customers.

On the other hand, the amount of oil supplied by the refueling device is limited by the measurement law.
100l 'i:' displays the refueling amount to the 1 yen digit, but the POS terminal that collects all records of the refueling amount for each customer for credit customers only records up to 10 l. /1
Currently, the number of 00Ij is often rounded down, and when this rounded-off amount is added up, the loss on the gas station side becomes enormous.

Therefore, oil supply devices have begun to be used that are equipped with means for automatically stopping oil supply when the amount of oil supplied reaches an infinitesimal amount after changing the flow rate according to a fixed interval by pressing a switch or operating a nozzle. However, even if there is no fraction in the refueling amount, there may be a fraction in the refueling amount depending on the unit price.

In addition, there are few places that charge cash customers in the 1 yen digit, and it is common for them to charge only 1 yen, and the amount for these services can add up to a huge amount.

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 vehicle, and the illustrated embodiment will be described below.

First, to explain based on Figure 1.2, (1) is the refueling device, and on the front there is a refueling amount display (2) and a refueling amount display (3).
, a unit price display (4), and a refueling hose (5) and a refueling nozzle (6) housed in a nozzle case (7). (8) is a box containing a card reader (9) and a change switch Q (l), which will be described later.

Prior to refueling, when the customer's card is read by a card reader (9), the reader (9) determines whether the customer is a credit customer or a cash customer and stores this in the memory circuit 0. At the same time, if it is a credit sale customer, the signal AI is output high to light up the display (2) to notify that the automatic stop for the quantity has been specified, and to give an instruction to the quantity-exact stop circuit. If the customer is a cash customer, a signal is output and the display 04) is turned on to notify that automatic stop for the amount has been designated, and an instruction is given to the amount exact circuit 0e.

At this time, by pressing change switch 00, signal C (one pulse) is output, and it is possible to change between stopping the amount and stopping the amount.

Next, when the nozzle (6) is removed from the nozzle case (7), the output signal n of the nozzle detection switch 0 changes from L (low level) to H (high level). The count values of the counting circuits aη and (g), which are the data for the minute, are returned to zero, and the indicators (31 and (2)) display zero, and the pump is sent to the motor control circuit H (as shown in the diagram).
Energize the motor (E) to drive.

When the nozzle is inserted into the fuel filler port (path shown) of all automobiles and refueling begins, the oil sent from the pump passes through the flow meter (path shown) and is guided to the hose (5) from the nozzle (6). However, each time the flow meter measures the unit oil amount ("/10001Vt), one flow pulse d is output from the transmitter Q, and the counting circuit a'i) counts this pulse d and calculates 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 (2) outputs an amount signal equivalent to 61 pulses to the counting circuit (b) based on the unit price set by the unit price setting circuit. (
g) counts this and displays the counted value on the display (2) as the refueling amount.

Note that the display device (4) displays the unit price set in the unit price setting circuit (E).

As the refueling process progresses and the fuel tank fills without automatic stoppage based on quantity or amount, the nozzle (6
) is returned to the case (7), the signal n changes from H to L, thereby deenergizing the motor (a) and resetting the memory contents of the memory circuit aη to prepare for the next refueling.

However, when the refueling flow rate is changed according to the predetermined "pa" by operating the lever (6) of the nozzle (6), the judgment circuit (c) regards this as a warning operation and sends a signal e (one noggle). ) is output. In the case of a credit customer, the signal a is first output from the memory circuit α, so the quantity stop circuit (to) starts operating due to the presence of the signal e and the signal a, and the counting circuit (17) If the count value is a round number, for example 1/101. When the digit of ``/1001'' becomes zero, a signal f is output and sent to the motor control circuit to de-energize the motor and stop refueling.On the other hand, if the customer is a cash customer, the signal f is output first. Since the amount is exactly in the stop circuit), the operation starts with the presence of signal e and signal
When the count value of the counting circuit (G) is a value with no fractions, for example, 10 yen or 1 yen, the signal g is output and applied to the motor control circuit 0, which completely de-energizes the motor and stops refueling. .

If the content stored in the notebook is not only the data of credit customers and cash customers, but also the data to distinguish between four-wheeled vehicles and two-wheeled vehicles, it will be possible to store four-wheeled vehicles as explained earlier. ni l
Stops are made in increments of 100 yen or 100 yen, and for vehicles with small fuel tanks such as motorcycles, stops are made in 101 increments or 10 yen, and for walk-in passengers who do not have card money. Change switch Q
Press O' once to stop the amount, and press once more to stop the amount.

Figure 3 is a diagram for controlling each oil supply device 0υ (A), NI), and 2 via the POS terminal cn, and the parts corresponding to Figures 1 and 2 are marked with the same numbers and a dash. appear.

The operation (m) includes a cart reader <95, a change switch Q (r), a switch (to) for specifying the refueling device in addition to the display θ6.a41, and a flinter (b) for issuing a refueling slip.
are equipped with υ, each with one card reader (
9r, change switch QQ, display (2), and a→ can control each refueling device, resulting in an inexpensive system.

In addition, when adopting this system, the card is read to confirm whether the amount is stopped or the amount is stopped, and then the designated switch is operated to specify the refueling device, and the next time it is operated for another customer. Later changes will not be possible.

By configuring the system as detailed above, we can obtain an automatic stop method according to the type of customer, and we are able to conduct all transactions accurately without having to cut off the small amount or perform extra services. It is.
