Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to an IC for a refueling device that is applied to a refueling fee payment system that allows refueling without paying cash on the spot at the time of refueling, for example. The present invention relates to a card, and particularly to an IC card for a refueling device that can prevent unauthorized use.

"Prior Art" In recent years, a storage device called an IC card has been developed in which an IC module including a CPU (central processing unit), memory, etc. is provided inside a credit card-like plastic case.

This IC card has a much larger storage capacity than conventional magnetic cards, and the information stored in the memory will not be erased by external magnetic fields.
Since it has the advantage of being able to reliably retain information, it is being considered for use in many fields.

"Problems to be Solved by the Invention" By the way, when attempting to use the above-mentioned IC card to omit the exchange of cash (refueling fee) at the time of refueling,
For example, the following fee payment system can be considered. That is, each customer is provided with an IC card, and the refueling device is provided with a read/write device for exchanging data with the IC card. Then, the customer sets the IC card in the refueling amount read/write device to start refueling, and when refueling is finished, the data corresponding to the current refueling amount is stored on the IC card. to be written to memory. On the other hand, the customer inserts his/her IC card into an automatic payment machine installed in a gas station office or the like every predetermined period, and pays the fee corresponding to the amount of fuel refueled (refueling record) during the predetermined period. Do it like this. However, in the above-mentioned fee payment system using an IC card, there are cases where the customer does not pay the refueling fee and continues to refuel illegally without paying the fee, or when a third party obtains the IC card that the customer has lost. It is conceivable that a person may refuel illegally, so it has been a challenge to prevent such unauthorized use.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an IC card for a refueling device that can prevent unauthorized use.

"Means for Solving Problems" The present invention includes a customer-specific registration number storage area that stores registration number data set in advance for each owner, and a storage means having a refueling performance storage area in which refueling performance data corresponding to the refueling amount that has been refueled is sequentially written; and a refueling permission determination flag storage area that indicates whether or not the next refueling is permitted; and the customer-specific registration. The data read from the number storage area and the refueling permission determination flag storage area is transferred to the refueling device, and the refueling performance data is calculated based on the data transferred from the refueling device and stored in the refueling performance storage area. The present invention is characterized by comprising a control means for writing and rewriting the storage contents in the refueling permission determination flag storage area based on the refueling performance data in the refueling performance storage area.

"For Collar" By comparing the registration number data read from the customer-specific registration number storage area by the control means of the IC card for the refueling device with the registration number data input by the customer into the refueling device, ownership of the IC card is determined. It is determined whether or not the person is the same as the customer who is about to refuel, and the content stored in the refueling permission determination flag storage area, which is rewritten based on the refueling record data in the refueling record storage area, is referred to. Based on this, it is determined whether refueling is permitted this time.

Each component 31, 32, 45°46.47 of the customer service device 48 described above,
The nozzle switch 24, the refueling amount indicator 25, the motor drive circuit 51, and the flow rate pulse transmitter 53 are all connected to the I10 interface 43.

In the above configuration, the operation when refueling is received from the refueling device 20 using the IC card 1 will be described. 7 and 8 are flowcharts for explaining each operation of the refueling device 20 and the IC card 1. FIG. First, the IC
When the card 1 is inserted into the card insertion slot 33, this is detected by the card insertion detector 45, and the process proceeds from step SPI to step SP2 shown in FIG. Next, step SP2. At the fuel supply level indicator 25 and customer service panel 30
The display unit 31 of the IC card is reset and initialized, and in steps S and P3, the IC card! Request the transfer of customer-specific registration number data, customer-specific unit price data, and refueling permission determination flag.

On the other hand, on the IC card I side, when the card is inserted into the card insertion slot 33 and power is supplied from the connecting device 46, the refueling amount count area 13 and the refueling amount temporary storage area 14 are cleared (steps shown in FIG. 8). 5P51). Then, upon receiving a transfer request from the refueling device 20 (step 5
p52), the registration number data, unit price data, and refueling permission determination flag are read from the customer-specific registration number storage area 101 and the customer-specific unit price data storage area 11 and the refueling permission determination flag storage area 16, and are transferred to the refueling device 20 (step 5P53). Next, the refueling device 20 receives each transferred data (step SP4) and stores it in the RAM.
42 predetermined areas (step SP5).
). Then, it is determined whether or not refueling is possible this time by referring to the refueling permission determination flag temporarily stored in the RAM 42 (step 5P6). That is, the refueling permission determination flag stored in the RAM 42 is stored in the EEPROM of the IC card 1.
Since this corresponds to the refueling permission determination flag in 7, it is determined whether or not refueling is possible at this time by referring to the contents of this refueling permission determination flag (whether or not it is set). Here, if it is determined that refueling is possible this time,
Proceeding to step SP7, if it is determined that refueling is not possible this time, stage 5T3 (card return processing), which will be described later.
Proceed to. Next, in step SP7, the customer service panel 3
The message "Please enter your registration number" is displayed on the display 31 of 0, and the customer is instructed to enter the registration number.

Here, for example, when the customer inputs the registration number by operating the operation keys 32 in the order of 1 → 2 → 3 → 4 → No, the process advances from step SP8 to step SP9, and the registration number stored in the RAM 42 is - Compare the registration number data input from the operation key 32 with the registration number data.

If both registration number data match, proceed from step 5PIO to step 5PII, and if they do not match, proceed to stage 5T.
Proceed to 3 (card return processing).

In this case, since the registration number data stored in a predetermined area in the RAM 42 is a type of PIN number set for the owner of the IC card 1, Even if a person tries to refuel illegally, he cannot receive refueling unless he inputs the customer-specific registration number assigned to the IC card 1 using the operation key 32. Next, in step 5PII, the display 31 of the customer service panel 30 displays the message "Please enter the preset fuel amount or preset fuel amount" and instructs the customer to input the preset value. Here, for example, when the customer operates the operation keys h'2 in the order of 4 → 0 → Q and inputs the preset oil supply amount, during this input, the process advances from step 5P12 to stage STI, where the preset value setting process is performed. , and when the input is completed, the process advances from step 5P12 to step 5P13. Then, when the customer removes the refueling nozzle 22 from the nozzle hook 23, the nozzle switch 24 is turned on, and the pump drive motor 50 is started.Step 5P14
.

), start the preset lubrication processing operation (

stage ST2). Next, while the refueling device 20 is performing the refueling process in stage ST2, when the customer inserts the outlet of the refueling nozzle 22 into the refueling port of the automobile and pulls the operating lever of the refueling nozzle 22, refueling is started. Thereafter, a flow rate pulse signal corresponding to the amount of oil supplied is output from the flow rate pulse transmitter 53.

Then, the CPU 40 on the oil supply device 20 side counts the flow rate pulse signals supplied from the flow rate pulse transmitter 53 via the I10 interface 43, and displays the obtained oil supply amount data one by one on the oil supply amount display 25. On the other hand, a flow rate pulse signal is supplied to the C card l via the 110 interface '43 and the connecting device 46. Then, the CPU 5 on the IC card I side proceeds from step 5P54 to step 5P55 shown in FIG. 8 during the period when the flow rate pulse signal is being supplied. Step 5P5
5, the flow rate pulse signal is counted using the oil supply amount count area 13, and the oil supply amount data is calculated based on this. Next, in step 5P56, the refueling amount data read from the refueling amount count area 13 is multiplied by the unit price data read from the customer unit price data storage area 11, and the refueling amount data obtained thereby is stored in the refueling amount temporary storage area 14. Store in. These steps 5
P55 and step 5P56 are repeated until the flow rate pulse signal is no longer supplied, and then, when the flow rate pulse signal is no longer supplied, the process advances from step 5P54 to step 5P57.

Next, the refueling of the preset value (refueling amount or refueling amount) set by the customer is completed, and the customer operates the refueling nozzle 22.
When applied to the nozzle hook 23, the nozzle switch 24 is turned off, and the process proceeds from step 5P15 to step 5P16 shown in FIG. 7, where the pump drive motor 50 is deenergized.
Step 5P1 to transfer the refueling end signal to the IC card l
7) Read the date data previously stored in a predetermined area in the RAM 42 and transfer it to the IC card 1 (step 5P18). On the other hand, the CPU on the IC card l side
5, when the refueling end signal is supplied from the refueling device 20, the process proceeds from step 5P57 to step 5P58, and when the date data is further supplied, the process proceeds to step 5P58.
Then proceed to step 5P59. And this step 5
At P59, the date data supplied from the refueling device 20 is stored in the date data temporary storage area 12, and then
In step 5P60, the date data in the date data temporary storage area 12, the refueling amount data in the refueling amount count area 13, and the refueling amount data in the refueling amount temporary storage area 14 are stored in the refueling performance storage area 15. Then, in the next step SP61, it is determined whether or not the next refueling is possible based on each data in the refueling record storage area 15. In other words, ■ If the number of refuelings reaches a predetermined number, ■ If the total amount of refueling up to this time reaches a predetermined amount, ■ If the total amount of refueling amount up to this time reaches a predetermined amount, ■ If the total amount of refueling up to this time reaches a predetermined amount, If the date interval between the refueling date and the current refueling date is greater than or equal to the predetermined interval, it is determined that the next refueling is not possible and the process proceeds to step 5.
The process proceeds to step 62, where the refueling permission determination flag is reset, and then the process proceeds to step 5P63. On the other hand, if none of the above conditions (1) to (2) apply, the process directly advances to step 5P63. Finally, the CPU 5 on the IC card 1 side transfers the refueling permission determination flag read from the refueling permission determination flag storage area 16 to the refueling device 20, and ends all operations. At this time, when the CPU 40 on the fueling device 20 side receives the fueling permission determination flag from the IC card 1, the CPU 40 at step SP+9
The process then proceeds to step 5P20, where the data is stored in a predetermined area of the RAM 42.

Then, in step 5, it is determined whether or not the next refueling is possible by referring to the refueling permission determination flag stored in the RAM 42.
p21), if the next refueling is not possible, step 5 P22
After displaying the message "next refueling not possible" on the display 31 of the customer service panel 30 for a predetermined period of time, the process proceeds to stage ST3; on the other hand, if the next refueling is possible, step 5P2
At step ST3, the display 31 displays "Next Refueling Cylinder" for a predetermined period of time, and then the process proceeds to stage ST3. Finally, in stage ST3, the IC card 1 is returned to the customer and all operations are completed. In addition, if the customer confirms that "next refueling is not possible" on the display 31, or at predetermined intervals, the customer must insert the IC card l into an automatic payment machine installed in the gas station office, etc. A fee corresponding to the amount of refueling received (refueling record) is paid. In this case, the storage contents of the refueling record storage area 15 in the EEPROM 7 of the IC card 1 are cleared and the refueling permission determination flag is set.

According to the embodiment described above, even if a third party who has obtained the IC card 1 that the customer has lost attempts to refuel illegally,
Unless the customer-specific registration number assigned to the IC card 1 is input from the operation key 32, refueling cannot be obtained, and unauthorized use can be prevented. In addition, ■ If the number of refueling reaches a predetermined number, ■ If the total amount of refueling up to this time reaches a predetermined amount, ■ If the total amount of refueling amount up to this time reaches a predetermined amount, ■ If the total amount of refueling up to this time reaches a predetermined amount, If the date interval between the refueling date and the current refueling date is longer than the predetermined interval, the next refueling will be impossible and the customer will continue to refuel illegally without paying the refueling fee. can be prevented.

In the embodiment described above, the flow rate pulse signal supplied from the refueling device 20 is counted on the IC card 1 side to calculate the refueling amount data.
Of course, the fuel supply amount data counted on the 0 side may be transferred to the IC card 1.

A control means is provided for writing in a storage area and rewriting the stored content in the refueling permission determination flag storage area based on the refueling performance data in the refueling performance storage area, so that the customer does not pay the refueling fee and is in arrears. It is possible to prevent unauthorized use, such as continuing to refuel illegally while the IC card is left in place, or a third party who obtains the IC card that the customer has lost to refuel illegally.
