Description

DETAILED DESCRIPTION OF THE INVENTION In a system for refueling using a refueling ticket in which the amount of residual oil is recorded, it is possible to refuel in excess of the amount of residual oil recorded in the refueling ticket. The refueling amount is recorded as a negative value on the refueling ticket, and when the new refueling ticket is issued, the residual oil amount obtained by subtracting the excess refueling amount is recorded on the refueling ticket.

TECHNICAL FIELD The present invention relates to an operating method of a system for refueling using a magnetic card in which the number of refuelable (liters) is recorded as a residual oil amount.

[Prior Art] The above magnetic card is known as a refueling ticket. In some cases, the amount of residual oil recorded on the refueling ticket brought by the customer is less than the amount of refueling desired by the customer. In such a case, conventionally, first of all, the refueling ticket brought by the customer is used to refuel the remaining amount. Then, the customer was asked to purchase a new refueling ticket, refueling was restarted using this new refueling ticket, and refueling was completed for the remaining portion.

According to such an operation method of the refueling system, there is a problem that the refueling operation has to be performed in two steps, which makes the operation complicated. Further, there is a drawback that the processing time is long because the procedure of refueling operation, issuance of a new refueling ticket, and refueling operation is required.

[Object of the Invention] An object of the present invention is to simplify and speed up the processing even when refueling exceeds the residual oil amount indicated by the fuel ticket.

[Structure and Effect of the Invention] The present invention is a system for refueling using a refueling ticket in which the amount of remaining oil is recorded. A new residual oil amount is calculated by subtracting the amount of refueling received from the weighing machine from the stored residual oil amount. If the calculated new residual oil amount is negative, that fact and the new residual oil amount are calculated. When the absolute value is recorded on the refueling ticket, the old residual oil amount of the old refueling ticket is read and stored when the new refueling ticket is issued, and the old residual oil amount read from the old refueling ticket shows a negative value. Is characterized in that a value obtained by subtracting the absolute value of the old residual oil amount from the input purchase amount is recorded as a new residual oil amount on a refueling ticket and a new refueling ticket is issued.

According to the present invention, it is possible to refuel using a refueling ticket brought by a customer in an amount exceeding the amount of residual oil recorded therein. Then, when the fuel is replenished in excess of the residual oil amount, the excess amount is recorded as a negative value on the previous refueling ticket. Then, when issuing a new refueling ticket to the same customer, the negative refueling amount is settled. That is, the amount of residual oil obtained by subtracting the above excess amount from the amount of newly refueled fuel is recorded as the new amount of residual oil on the new refueling ticket.

In this way, even if refueling exceeds the amount of remaining fuel on the refueling ticket, only one refueling operation and one new reissuing ticket issuing operation are required, so that the operation and processing can be simplified and speeded up. can do.

Description of Embodiments 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, and a floppy disk for storing transaction data. -Disk 19 is connected. Further, in the central device 10, a card reader 14 for reading refueling ticket data, a display 15 for displaying refueling data and other transaction data, a purchase refueling amount when issuing a new refueling ticket, and other data are input. Keyboard 16 for issuing, Blinter 17 for issuing sales slips, etc. and Card reader / writer 18 for issuing new refueling tickets
Etc. are provided, and these are connected to the CPU 11. The fueling machine and the weighing machine 30 are controlled by the CPU 11 via the control device 31.

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 selecting a refueling machine, inputting a refueling command, etc., a card reader / writer 22 for reading the magnetic data of the refueling ticket and recording the amount of remaining oil on the refueling ticket. A printer (not shown) for printing refueling data on a refueling ticket or issuing a refueling slip is provided.

FIG. 2 shows an example of a fuel ticket. The refueling ticket is a printable magnetic card, and has a magnetic stripe 40 attached thereto and a print area. On the magnetic stripe 40, a code indicating a refueling ticket, a refueling company code, an expiration date, the latest remaining amount of oil, a code of the owner, etc., if necessary, are 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, the amount of remaining oil, etc. 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 negative, 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 60).

If the refueling ticket is valid, the keyboard of terminal 20
A lubricator is selected using 23, and a lubrication possible command is sent to the central unit 10 (steps 54, 55). The refueling instruction is then sent to the old oil machine. As a result, the refueling machine becomes ready for refueling.

When the refueling is completed (step 56), the refueling amount is transmitted from the corresponding weighing machine 30 through the central device 10, and is received by the corresponding terminal 20 (step 57). Step
The received refueling amount is subtracted from the remaining oil amount in the refueling ticket data read at 51, and the subtraction result is printed as a new remaining oil amount on the refueling ticket and encoded in the magnetic stripe 40. If the subtraction result is negative, that fact is also printed and magnetically recorded (step 58).

Finally, the refueling slip is issued and the refueling ticket is released (steps 59, 60).

FIG. 5 shows the procedure of the refueling ticket issuing process. This processing is mainly performed in the central unit 10.

First, the refueling ticket issuing mode is selected by the keyboard 16,
Since the old refueling ticket is inserted into the card reader / writer 18,
The data is read and stored in the card data area of RAM 13 (see FIG. 3) (step 71). The validity of the refueling ticket is checked based on this card data (step 72), and if OK, the old refueling ticket is invalidated (for example, all zeros are magnetically recorded on the magnetic stripe) (step 73). , 74), discharged (step 7)
Five). If the validity check is NG, an alarm is output and the old refueling ticket is discharged (step 81).

When a blank card is built in the central device 10, this card is transported to the location of the reader / writer 18,
If not, a blank card is inserted (step 76). Next, the number of purchases (liters) (purchased amount) is entered using the keyboard 16, and this is read and R
It is stored in AM13 (step 77) (Q1 in Fig. 3).
Next, the remaining oil amount of the old refueling ticket is checked by the data in the card data area of RAM13, and if the remaining oil amount of the old refueling ticket is negative, the absolute value is read out, and the amount Q2 is RAM13.
Stored in. Then, Q1-Q2 are calculated, and the result becomes the new residual oil amount Q3. (Step 78). Predetermined data excluding the amount of remaining oil in the card data area, new amount of remaining oil Q3, issuance date, effective date, etc. are printed and encoded on a blank card to create a new refueling ticket (step 79). ). Then, a sales slip is issued (step 80), and the created new fuel ticket is discharged (step 80).
81).

If the amount of remaining oil on the old refueling ticket is zero, the process of step 78 is unnecessary and the purchase amount becomes the new amount of remaining oil Q3. If the remaining oil amount of the old refueling ticket is positive, the calculation of Q3 = Q1 + Q2 is performed in step 78.
