Description

  The present invention relates to a gas station system using a card.

In recent years, refueling using various cards has been performed at gas stations.
As the card, a prepaid card having a monetary value (hereinafter referred to as “prica”) and a credit card permitting refueling based on the credit of a user (user) are mainly used (for example, Patent Document 1).
Japanese Patent Laying-Open No. 2005-332017 (FIG. 2)

However, the system using the prica has the following drawbacks.
Because it is necessary to pay the deposit in advance in relation to the law on the rules for prepaid certificates (commonly known as the Prica Law), a financial burden arises at the gas station.
In addition, since a large amount of precursed in advance is stored, strict management such as theft prevention is required.
Furthermore, if the printing area of the precursor is used up, the precars are discarded and a new one is issued, which increases the running cost and is not preferable from the viewpoint of environmental conservation.

  On the other hand, in the case of a credit card, the card itself has the credit value of the individual user. Therefore, if the card is lost, there is a risk that a large amount of loss may occur, so there are many users who do not use from this point of view. For this reason, it is difficult to expand the use of gas stations.

  Therefore, a main object of the present invention is to provide a gas station system using a card that is easier to use than a prepa or credit card for both users and gas stations.

  In order to achieve the above object, a filling station system according to the first aspect of the present invention includes a nozzle that discharges fuel oil, a measuring unit that measures the amount of fuel oil supplied from the nozzle, and an input unit that inputs refueling schedule information. Metering control means for controlling refueling according to the refueling schedule information and the refueling amount, a first reader for reading a first card ID of a first card for storing an identification symbol, and the first reader The POS main body outputs a refueling permission signal to the metering control means with information from an authorization center that stores credit information as to whether or not the first card corresponding to the first card ID read in step S3 can be used. The balance information is received from a second reader that reads the second card ID of the second card that stores the identification symbol, and a balance management center that stores the balance corresponding to the second card ID. Connected to the communication PC for outputting a limited refueling permission signal for permitting refueling within the range of the balance, the metering control means, the second reader, the POS main body and the communication PC, and the refueling permission signal from the POS main body Is input to the metering control means, and when the limited refueling permission signal including the balance is input from the communication PC, the refueling permission signal is calculated from the refueling schedule information. A switching machine that determines whether or not the scheduled usage amount is within the range of the balance and outputs a signal for permitting refueling to the measurement control means when it is within the range; The control of refueling based on the refueling schedule information within the range of the balance by the permission signal and the control of refueling based on the refueling schedule information by the refueling permission signal from the POS main body It means characterized in that said on allow.

  Such a gas station system can be constructed by adding to an existing (existing) gas station in addition to newly installing a gas station.

  That is, the filling station system according to the first aspect of the invention includes a nozzle that discharges fuel oil, a metering unit that measures the amount of fuel oil supplied from the nozzle, an input unit that inputs refueling schedule information, and the refueling schedule information. And a weighing control means for controlling the refueling according to the refueling amount, a first reader for reading the first card ID of the first card for storing the identification symbol, and the first reader read by the first reader. A POS main body that outputs a refueling permission signal with information from an authorization center that stores credit information as to whether or not the first card corresponding to one card ID can be used, and refueling permission from the POS main body In an existing filling station system in which the metering control means can perform control of refueling based on the refueling schedule information by a signal, the second card ID of the second card storing the identification symbol is set. And a communication PC that receives information on the balance from a balance management center that stores a balance corresponding to the second card ID and outputs a limited refueling permission signal that permits refueling within the range of the balance And when the refueling permission signal is inputted from the POS body, the refueling permission signal is output to the weighing control means. On the other hand, when the limited refueling permission signal including the balance is input from the communication PC, it is determined whether or not the planned use amount calculated from the refueling schedule information is within the range of the balance, And a switching machine that outputs a signal for permitting refueling to the metering control means when it is within, the refueling schedule within the range of the balance by a limited refueling permission signal from the communication PC The control of the fuel supply based on the broadcast can be offered by said metering control means.

In the first invention, the first card stores the first card ID corresponding to the credit information, and is therefore a so-called credit card.
On the other hand, the second card stores a second card ID corresponding to the balance of the balance management center, and is therefore a so-called electronic money card.

Since the card used in the gas station system of the first invention is a credit card and an electronic money card, unlike the pre-curror, it is not necessary to pay a deposit in advance, so that no financial burden is generated at the gas station.
In addition, since it is not necessary to store a large amount of precursed in advance, management such as theft prevention becomes unnecessary.
Further, since there is no need to provide a printing field and it is not necessary to discard the card, there is an advantage that the running cost is reduced.
In addition, unlike Prica, there is a possibility of expanding the usage other than the gas station.

  Since both the electronic money and the credit can be used in this system, the user can select one of them, which is convenient and can aim for sales expansion.

  Here, since the POS main body (POS terminal) has a specification corresponding to the POS system that has existed for a long time, it does not have a communication function via the Internet. Therefore, in the first invention, a communication PC different from the POS main body is provided and can be connected to the balance management center via the Internet.

  In addition, the specifications of the POS main unit, that is, software such as hardware and signal format, etc., are unknown at existing gas stations. However, in this case as well, a separate communication PC is provided to hinder the construction of the system. I try not to come.

  On the other hand, by providing a switching machine, either the POS main body or the communication PC can permit refueling to the measurement control means.

  In particular, in the first aspect of the invention, the same system can be adopted not only for a newly installed gas station but also for an existing gas station, so that it can be easily introduced at an existing gas station.

  On the other hand, the filling station system according to the second aspect of the present invention includes a nozzle that discharges fuel oil, a measuring means that measures the amount of fuel oil supplied from the nozzle, an input means that inputs refueling schedule information, and the refueling schedule information. Information on the balance from a balance control center for storing the balance corresponding to the card ID, a weighing control means for controlling the refueling according to the refueling amount, a reader for reading the card ID of the card storing the identification symbol And a communication PC that outputs a limited refueling permission signal that permits refueling within the range of the balance, and a refueling based on the refueling schedule information within the range of the balance based on the limited refueling permission signal from the communication PC. The metering control means can be controlled.

  In the second invention, the card ID corresponding to the balance of the balance management center is stored, and therefore the card is an electronic money card.

In the second invention, a credit card cannot be used, but it has the advantages of electronic money and has the advantage that the system structure is simple and the initial cost is low.
Therefore, the utility value as a small-scale gas station system is high.

  Embodiments of the present invention will be described below with reference to the drawings.

Example 1

The nozzle detection means 30 detects whether the nozzle of the weighing machine 3 has been removed from the nozzle hanger.

  The first input / output device 10 includes a display 11, a first reader 12, an input means 13, a printer 14, and the like. The input means 13 is used to set oil supply schedule information such as the type and quantity (how many liters or full) of oil to be supplied.

The metering means 31 measures the amount of fuel oil discharged from the nozzle in real time and displays it on a metering display (not shown).
The meter control unit 32 monitors the amount of oil supplied from the metering means 31 in real time, and based on the fuel supply schedule information, the rotation of the pump (not shown), the opening degree of the flow control valve, and the opening / closing of the on / off valve Is controlled so that a predetermined amount of fuel oil is supplied.

The first input / output device 10 in FIG. 2 is connected to a POS main body (POS terminal) 1 by Ethernet (registered trademark) via a HUB.
In FIG. 3B, the first reader 12 reads the card ID of the credit card C1 inserted by the user, and outputs the card ID to the POS main body 1 via the HUB.
The refueling schedule information input from the input means 13 is transmitted to the POS main body 1 via the HUB.

  Each weighing machine control unit 32 is connected to one centralized controller SSC for self through SS-LAN. The centralized controller SSC in FIG. 2 is provided in a self-service gas station, and is connected to the POS main body 1 by SS-LAN.

  The POS main body 1 is connected to an authorization center 19 via a communication line such as ISN. The authorization center 19 stores credit information indicating whether or not the credit card C1 can be used.

  The POS main body 1 outputs a refueling permission signal to the centralized controller SSC using credit information from the authorization center 19. The refueling permission signal is held by the centralized controller SSC, and is output from the centralized controller SSC to the weighing machine controller 32 when the operator operates the centralized controller SSC. When this refueling permission signal is received, refueling is performed by operating the lever of the nozzle, and the meter control unit 32 controls refueling based on the refueling schedule information.

The POS main body 1 includes a first storage unit 18 for performing sales management and inventory management described below.
As basic sales management of fuel oil, when and how many nozzles (or what metering machine) how many oils (how many liters, how many yen) were refueled (for sales form management, cash and If it is other than cash, the card number is also recorded in the first storage unit 18. In other words, the first storage unit 18 stores the refueling date and time, nozzle No. , Oil type, amount of oil supplied, amount of oil supplied, (payment method, card No.), etc., and based on this memory, the POS main unit 1 is provided with the amount of oil and the amount of money for each meter, nozzle, and oil type. Calculate daily and monthly reports (weekly reports) and create sales management materials.
The POS main body 1 can also manage the inventory of each underground tank (oil type) by processing the stored contents.

Next, an additional part added to the existing POS system will be described.
As shown in FIG. 1, the additional part includes a communication PC 2, a switching device 4, a router 5, a second input / output device 20, and the like.

The second input / output device 20 is added for each weighing machine 3A.
As shown in FIG. 3A, the second input / output device 20 includes a display 21, a second reader 22, an input means 23, a printer 24, and a bill validator 25.

  The input means 23 is used to set oil supply schedule information such as the type and quantity (how many liters or full) of oil to be supplied.

As shown in FIG. 1, the second input / output device 20 is connected to the communication PC 2 via, for example, RS-232C via the switching device 4.
3A, the second reader 22 reads the card ID of the electronic money card C2 inserted by the user and outputs the card ID to the switching device 4.

  The switching device 4 in FIG. 1 is connected to the second input / output device 20, the centralized controller SSC, the POS main body 1 and the communication PC 2, and selectively connects two of them.

  The communication PC 2 is connected to the balance management center 29 via the router 5. The balance management center 29 stores balance information corresponding to the card ID of each electronic money card C2.

  Refueling schedule information from each second input / output machine 20 is input to the switching machine 4. The communication PC 2 outputs a limited refueling permission signal to the switching device 4 based on the balance information from the balance management center 29.

  The switching device 4 includes a determination unit 41. When the limit refueling permission signal is input from the communication PC 2, the determination unit 41 is within the range of the balance stored in the balance management center 29 from the input unit 23. It is determined whether or not refueling is possible based on the inputted refueling schedule information. As a result of the determination, when the planned usage amount calculated from the refueling schedule information is within the range of the balance, the switching device 4 outputs a refueling permission signal to the centralized controller SSC, while when the balance exceeds the balance range. Sends a signal that causes the second input / output device 20 to reset the oil type and quantity. The refueling permission signal is held by the centralized controller SSC and is output from the centralized controller SSC to the weighing machine controller 32 when the operator operates the centralized controller SSC. When this refueling permission signal is received, refueling is performed by operating the lever of the nozzle, and the meter control unit 32 controls refueling based on the refueling schedule information.

The communication PC 2 includes a second storage unit 28 for performing sales management and inventory management similar to the POS main body 1.
Note that the management contents, the storage contents of the second storage unit 28, and the like are the same as those of the POS system described above, and a description thereof is omitted.

  1 is installed between the centralized controller SSC of FIG. 2 and the POS main body 1, and the second input / output device 20 and the communication PC 2 are connected to the switching machine 4. Connecting.

  When the refueling permission signal is input from the POS body 1, the switching machine 4 outputs the refueling permission signal to the centralized controller SSC.

Next, the operation of the system of FIG. 1 will be described with reference to the charts of FIGS.
First, the case where the credit card C1 is used will be described.

  4, when the user inserts the credit card C1 into the first reader 12, the card ID of the credit card C1 is transmitted from the first input / output device 10 to the POS main body 1 via the HUB.

  In the next step S2, when the POS main body 1 transmits the card ID to the authorization center 19 and inquires about the credit information, in step S3, the credit information indicating whether or not the card with the card ID can be used is displayed. 1, the authorization center 19 transmits and responds.

  On the other hand, when the user who has inserted the credit card C1 sets the oil type in step S50 and the quantity in step S51 from the input means 13, the set oil type and quantity are stored in the POS main body 1 via the HUB. Is output. When the credit information is “usable”, in the next step S4, the POS main body 1 outputs a refueling permission signal S including information on the oil type and quantity to the switching machine 4, and the switching machine 4 outputs the refueling permission signal S. Is sent to the centralized controller SSC. The centralized controller SSC holds the refueling permission signal.

  Thereafter, the user removes the nozzle from the nozzle hanger in step S52, a nozzle ON signal is output from the nozzle detecting means 30 (FIG. 3) to the centralized controller SSC from the meter control unit 32, and the operator at the gas station is concentrated. When the operation button of the controller SSC is pressed, the centralized controller SSC that has held the refueling permission signal sends a refueling permission signal that permits refueling in the range of the set oil type and quantity in step S5. 32.

  Accordingly, the process proceeds to step S53, where fuel oil is discharged from the nozzle (refueling is started), and a refueling start signal is transmitted from the meter controller 32 to the centralized controller SSC.

After that, when refueling is completed and the user returns the nozzle to the nozzle hanger in step S54, this is detected by the nozzle detecting means 30, and a refueling completion signal is output from the meter control unit 32 to the switching machine 4 via the centralized controller SSC. Is done. The switching machine 4 outputs the signal to the POS main body 1. The refueling completion signal includes information such as the type, quantity, and amount of oil actually refueled, and the POS main body 1 stores these in the first storage unit 18.
At the same time, the credit card C1 is discharged from the first reader 12 of the first input / output device 10 and the usage details are printed from the printer 14.

  Thus, the credit card C1 can be refueled based on the credit information and the refueling schedule information by the refueling permission signal S from the POS main body 1.

Next, a case where the electronic money card C2 is used will be described.
In this case, the user inserts a bill into the bill validator 25 in FIG. 3A as needed, and also inserts an electronic money card C2 into the second reader 22 to give money that can be used with the electronic money card C2. Can be charged.
At this time, the balance used for each ID card of the electronic money card C2 is updated and stored in the balance management center 29 via the switching device 4 and the communication PC 2 of FIG.

  When the user inserts the electronic money card C2 into the second reader 22 in step S11 of FIG. 5, the card ID of the electronic money card C2 is transmitted from the second input / output device 20 to the communication PC 2 via the switching device 4. The

  In the next step S12, the communication PC 2 transmits the card ID of the electronic money card C2 to the balance management center 29 and inquires about the balance. In step S13, the balance management center 29 searches for the balance corresponding to the card ID. Then, the balance information is transmitted to respond to the communication PC 2.

  In the next step S <b> 14, the communication PC 2 transmits to the switch 4 a limited refueling permission signal L that permits refueling within the range of the balance for the card ID. The switching machine 4 temporarily stores the balance of the limited refueling permission signal L and the card ID.

On the other hand, when the user who has inserted the electronic money card C2 sets the oil type in step S50 and the quantity in step S51 from the input means 23, the set oil type and quantity are output to the switching device 4. .
The switching machine 4 compares the planned usage amount calculated from the input quantity and oil type with the balance, and if it is within the balance, transmits a refueling permission signal to the centralized controller SSC in step S100. . This signal includes oil type and quantity information within the range of the balance while permitting refueling. On the other hand, when the planned usage amount exceeds the balance, the fact is output to the second input / output device 20 in FIG. 3A, and the second input / output device 20 resets the quantity on the display 21. To display.

That is, when the amount of money or the number of liters is input from the input means 23 as the quantity of the scheduled refueling information, the usage amount calculated from the amount, the number of liters, and the oil type is within the range of the balance. If the input amount or the number of liters is included in the refueling permission signal as quantity information, on the other hand, when it is out of the balance, the resetting is displayed.
Further, when “filled” is input from the input means 23 as the quantity of the refueling schedule information, the balance as the upper limit of refueling instead of the “filled” information as the refueling desired amount as the balance information. Is included in the refueling permission signal.

  Thereafter, in step S15 of FIG. 5, a refueling permission signal is output from the centralized controller SSC to the weighing machine control unit 32 as in step S5.

  Accordingly, the process proceeds to step S53, where fuel oil is discharged from the nozzle (refueling is started), and a refueling start signal is transmitted from the meter controller 32 to the centralized controller SSC.

  Here, in the case where the amount or the number of liters is input from the input means 23 within the range of the balance as the quantity of refueling schedule information, if it is not “filled” during refueling, the amount or the number of liters is reached. When refueling is performed and “filled” is achieved during refueling, refueling is stopped when the fuel is filled.

  On the other hand, when “filled” is input from the input means 23 as the quantity, refueling can be performed until the refueling amount reaches the balance or “fills”.

  The next step S54 is the same as in the case of the credit card C1 described above, but when the refueling completion signal is output to the switching device 4, the switching device 4 outputs the signal to the communication PC. Information such as the oil type, quantity, and amount of money included in the refueling completion signal is stored in the second storage unit 28 of the communication PC 2.

In step S54, the communication PC 2 that has received the refueling completion signal transmits the usage amount corresponding to the usage to the balance management center 29 via the router 5 together with the card ID in step S16.
In the next step S17, the balance management center 29 subtracts the usage amount from the balance corresponding to the card ID, updates and stores the balance corresponding to the card ID, and means that the usage is accepted. A response signal is transmitted to the communication PC 2.

  In the next step S18, when the communication PC 2 transmits a completion notice to the second reader 22 via the switching device 4, the second reader 22 ejects the electronic money card C2 and uses the printer 24 (FIG. 3). Is printed.

  In this way, the electronic money card C2 can be refueled based on the refueling schedule information within the range of the balance by the limited refueling permission signal L from the communication PC2.

  By the way, in Example 1 of FIG. 5, since refueling is performed with the balance remaining in the balance management center 29, there are cases where fraudulent acts due to simultaneous use or the like cannot be prevented. An example in which this fraud prevention can be achieved will be described as a modification.

  FIG. 6 is a chart showing a modification of the first embodiment.

  This modification employs steps S32, 33, 36, and 37 of FIG. 6 instead of steps S12, 13, 16, and 17 of the first embodiment of FIG.

  In FIG. 6, in step S <b> 32, when the second card ID is transmitted from the second reader 22 to the communication PC 2 via the switching device 4, the total amount of the balance is transferred from the communication PC 2 to the balance management center 29. A full usage request is sent requesting the use of. Accordingly, in step S33, the balance management center 29 transmits the balance to the communication PC 2 and updates the balance to 0 yen. Thereby, fraud by simultaneous use can be prevented.

  On the other hand, in step S36, when the communication PC 2 receives a refueling completion signal indicating that refueling has been completed from the measurement control unit 32 via the centralized controller SSC and the switching device 4, the balance is output from the balance management center 29. The remaining usage amount obtained by subtracting the usage amount is output to the balance management center 29. In response to this, in the next step S37, the balance management center 29 transmits a reply indicating that the remaining balance has been received to the communication PC 2 as a balance response, and at the same time updates and stores the remaining balance as a balance.

  In the first embodiment, the POS main body 1 is provided in addition to the communication PC 2. However, when newly installing a gas station, it is not necessary to provide the POS main body 1. This example is shown in Example 2 in FIGS.

Example 2
In the system of the second embodiment, a plurality of units or one weighing machine 3B is provided. Each weighing machine 3B includes a weighing machine control unit 32 in addition to devices such as nozzles and pumps as in the first embodiment.

  The system of the second embodiment is composed of a part added to the system of the first embodiment. Therefore, it is a system using the electronic money card C2, and the credit card C1 cannot be used.

  In this system, the input / output device 20 of FIG. 7, the storage unit 28 of the communication PC 2, and the reader 22 of FIG. 8 are respectively the second input / output device 20, the second storage unit 2, and the second of the first embodiment. It corresponds to the reader 22 and exhibits the same function.

  The operation when the electronic money card C2 is used by the system of the second embodiment is the same as that of the first embodiment as shown in FIGS. 9 and 10, and therefore the description thereof is omitted.

  In the above embodiment, the case of self is described, but the present invention can also be applied to a full service. In the case of full service, the centralized controller SSC is unnecessary. In this case, it communicates with the communication PC and the POS main body via the switching device 4 and serves as a master unit for the two weighing machine control units 32, with one weighing machine control unit 32 as a master and the other as a slave, It is desirable to be able to change the slave to the master so that it can cope with the failure of the master.

  Further, the electronic money card may be a magnetic card, or any other contact type or non-contact type. Further, in the case of the non-contact type, a mobile phone having a function of recognizing the unique number may be used.
