Description

Description: TECHNICAL FIELD The present invention relates to a system for refueling using a magnetic card in which a refuelable oil amount (for example, represented by liter) is recorded as a residual oil amount.

[Prior Art and its Problems] The above magnetic card is known as a refueling ticket. A customer who has brought a refueling ticket may desire to refuel all the remaining oil amount printed or encoded on the refueling ticket. In this case, conventionally, a clerk instructed the refueling amount to the refueling machine and the weighing machine by reading the remaining refueling amount from the refueling ticket and inputting the remaining refueling amount from the ten keys. Therefore, an error in reading the remaining oil amount or an input error may occur, and
There was a problem that it took 2 hours to operate.

[Object of the Invention] An object of the present invention is to provide a system capable of simplifying the refueling operation and accelerating the processing when refueling the entire remaining amount of the refueling ticket.

[Structure of the Invention] The present invention is a card reader / writer for reading / writing data including a residual oil amount on a fuel ticket, an oil supply amount input device for inputting an oil supply amount, an oil supply for which a given amount of oil supply can be controlled. Machine, refueling machine control means for refueling the refueling machine by the refueling quantity input from the refueling quantity input device, and the refueling quantity by the refueling machine from the remaining oil quantity in the refueling ticket data read by the card reader / writer. Calculate the new residual oil amount by subtracting,
In a refueling system using a refueling ticket equipped with a card renewal means for writing the new amount of remaining oil on the refueling ticket in the card reader / writer, when the remaining oil amount preset key and the remaining oil amount preset key are input. A residual oil amount refueling control means for controlling the refueling machine control means so as to refuel all of the remaining oil amount read by the card reader / writer is provided.

[Operation] When the customer desires to refuel all of the remaining oil amount on the refueling ticket, the clerk presses the remaining oil amount preset key. When there is a key input from the residual oil amount preset key, the residual oil amount refueling control unit controls the refueling machine control unit so that all of the residual oil amount read from the refueling ticket is refueled as the refueling amount, The fueling machine is instructed to refuel in the amount equivalent to the amount of remaining oil. The amount of oil equivalent to the amount of residual oil is supplied by the oil supply machine.

[Effects of the Invention] According to the present invention, in the case where all of the remaining oil amount of the refueling ticket is refueled, the clerk only presses the remaining oil amount preset key to refuel the portion corresponding to the remaining oil amount. There is no need for an operator to input the refueling amount from the refueling amount input device. By this,
The refueling operation can be simplified, and reading errors and key input errors do not occur.

[Embodiment] FIG. 1 shows the entire electrical configuration of a fueling system using a fuel ticket. The refueling system is composed of a central unit 10 and a plurality of terminals 20 connected to the central unit 10 by a transmission line. In addition, the refueling amount measuring machine provided in each of the refueling machines
30 is connected to the central unit 10.

The central unit 10 includes a CPU 11 for controlling refueling, controlling terminals, issuing a refueling ticket, and other controls. The CPU 11 has a ROM 12 for storing the program, a ROM 13 for storing data,
A floppy disk 19 driver for storing transaction data is connected. Further, in the central device 10, a card reader 14 for reading the data of the refueling ticket, an indicator 15 for displaying refueling data and other transaction data, and the amount of refueling purchased when a new refueling ticket is issued and other data are input. A keyboard 16 for issuing, a printer 17 for issuing a sales slip, and a card reader / writer 18 for issuing a new refueling ticket are provided, and these are connected to the CPU 11. The refueling machine and the calculator 30 have a control device 31
Controlled by the CPU 11 via the, the lubrication of the designated lubrication amount is performed.

The terminal 20 also preferably has a built-in CPU (not shown) and is connected to the CPU 11 of the central apparatus 10 via the transmission control circuit 21. Each terminal device 20 has a keyboard 23 for inputting a refueling amount, selecting a refueling device, inputting a refueling command, and the like.
Card reader / writer 22 for reading magnetic data of refueling ticket and recording data such as remaining oil amount on refueling ticket, and for invalidating refueling ticket if necessary, printing refueling data on refueling ticket, A printer (not shown) for issuing a refueling slip and the like are provided.

FIG. 2 shows an example of the keyboard 23 of the terminal device 20.

The keyboard 23 has function keys 41, numeric keys 42,
Product key 43, key 4 to select refueling machine (weighing machine 30)
In addition to 6, a quantity preset key 45 and a residual oil amount preset key 44 used when presetting the oil supply amount are provided.

The refueling ticket is a magnetic card that can be printed. The refueling ticket has a magnetic stripe attached and a printing area. The magnetic stripe has a code indicating that it is a refueling ticket, a refueling company code, an expiration date, the latest remaining oil amount,
If necessary, the owner's code or the like is magnetically recorded. Further, in the print area of the refueling ticket, data relating to refueling such as the date of issuing the refueling ticket, the date of refueling, the amount of refueling, and the amount of remaining oil is printed.

The flow of the refueling process is shown in FIG. This processing is mainly performed in the terminal device 20.

First, a refueling ticket is inserted into the card reader / writer 22 of the terminal 20 and its magnetic data is read (step 51). The validity of the card data is checked based on the read card data (step 52). For example, a formality check, whether the residual oil amount is not zero, and whether the expiration date has not passed are checked.
If the ticket is valid, go to the next step (step
53), if it is invalid, an alarm is issued and the refueling ticket is discharged (step 66).

If the refueling ticket is valid, the keyboard of the terminal 20
It is determined whether or not the 23 remaining oil amount preset key 44 has been pressed (step 54). When the residual oil amount preset key 44 is pressed, the latest residual oil amount read in step 51 is transmitted to the central unit 10 as the lubrication amount (step 55).
When the remaining oil amount preset key 44 is not pressed, the amount of oil supply is input using the number preset key 45 and the ten key 42, and this is read, and the instructed amount of oil supply is sent to the central unit 10 (step 56). ).

After this, press the lubricator selection key 46
Is selected, and this is read and sent to the central unit 10 together with the instruction to allow refueling (steps 57 and 58). The lubricator selection signal and the above-mentioned residual oil amount or oil supply amount together
May be sent to.

Now that the data necessary for refueling has been prepared, the central unit
The CPU 11 of 10 causes the designated refueling machine to start the refueling operation. The corresponding lubricator will refuel by the instructed residual oil amount or refueling amount.

When the refueling is completed (step 59), the refueling amount is transmitted from the corresponding weighing machine 30 via the central unit 10, and is received by the corresponding terminal 20 (step 60). Step
The received refueling amount is subtracted from the latest remaining refueling amount in the refueling ticket data read at 51, and the subtraction result becomes a new remaining refueling amount (step 61).

It is checked whether the new residual oil amount is zero (step 6
2) If it is zero, the inserted fuel ticket is invalidated (step 63). That is, the code 0 is encoded in the entire data area of the magnetic stripe of the fuel ticket and, if necessary, the fact that it is invalid is printed in the print area.

When the new residual oil amount shows a positive value instead of zero, this new residual oil amount is magnetically recorded as the latest residual oil amount on the magnetic stripe of the refueling ticket, and refueling is performed in the printing area of the refueling ticket. The date, refueling amount, latest remaining oil amount, etc. are printed (step 64).

Finally, the refueling slip is issued and the refueling ticket is released (steps 65, 66).
