Description

 Report of the Invention Patent for "SYSTEM AND METHOD FOR AUTOMATIC PAYMENT FOR FUEL GAS FILLING",

 [001] The present invention relates to a system for automatic payment of gas station fueling using vehicle identification by means of an RFID (radio frequency identification) transponder. In general, the system includes an in-vehicle RFID device that will be fueled at the gas station and cabinets installed on the gas station fueling islands. The offices concentrate the equipment used to identify, process and complete the financial discharge operation.

 [002] In accordance with the present invention, cabinets installed on supply islands provide decentralized control of supply and payment thereof. In addition, the cabinets described in the present invention allow a very small number of modifications to be made to supply islands already installed at gas stations.

 [003] The present invention further relates to a method for operationalizing said system.

Description of the prior art

 [004] Usually the payment for gas station supplies is made by traditional means such as credit and debit cards, checks and cash.

 [005] In addition, state-of-the-art payment systems using RFID technology to collect supplies comprise a number of antennas installed on the gas station roof that receive information from vehicles parked for supply.

Thus, as the antennas are arranged far from the transponders installed on the windshields of vehicles, it is common for interference, impairing the reading of electronic transponders, the processing of vehicle identification and the making of payment.

Thus, the state of the art presents as a problem the interference between the various readings that are taken at the gas station, which generates errors and interruption of the payment system.

In addition, the antennas on the gas station canopy communicate with a control center, usually installed at a convenience store or gas station office, which is responsible for processing all payment transactions using payment through vehicle identification through an RFID fransponder.

 Thus another disadvantage of the state of the art is the reliance on a single control center for sending and receiving payment data for all vehicles parked on the gas station islands. In the event that the control center becomes inoperative, there is no possibility of identifying the vehicle and processing the fuel payment.

A further disadvantage of the state of the art is the need for major structural works to be carried out at the gas station for the installation of antennas, the control center, and for the communication cables.

 Brief Description of the Invention

 The present invention utilizes RFID (Radio Frequency Identification) vehicle identification technology as its main tool.

[0012] The system of the present invention is comprised of an ephonic fransponder with RFID technology installed in a vehicle, which is used to identify the vehicle.

[0013] The system also includes cabinets or totem poles installed on the gas station supply islands. Cabinets or totems comprise all the equipment necessary for the identification, processing and completion of the financial discharge operation, which facilitates maintenance and adjustments. In addition, with the installation of the totems, it is possible to maintain the aesthetics of the pre-existing supply island at the gas station, avoiding the installation of equipment on the columns or the roof of the supply island.

 In the proposed system, vehicle identification and payment control are performed in a decentralized manner, without relying on rooftop antennas or a single control center.

[0016] The system of the present invention is considerably economical as it utilizes the existing infrastructure of the filling stations, requiring only minor modifications to the supply pump cabinets or supply islands, minimizing the need for cable routing work. and other installation infrastructure needs.

Brief Description of the Drawings

 The present invention will hereinafter be described in more detail based on an exemplary embodiment. To aid understanding the following figures are presented:

 Figure 1 shows a first exemplary embodiment of a gas station containing the payment system of the present invention;

Figure 2 shows a second exemplary embodiment of a gas station containing the payment system of the present invention; and Figure 3 - presents the equipments that make up the system proposed by the present invention.

Detailed Description of the Invention

 As shown in Figure 1, vehicle 12 parked at gas station 10 comprises an electronic transponder with RFID technology 11, which is used to identify vehicle 12.

In a preferred embodiment, the transponder 11 is an electronic tag composed of an electronic microcircuit connected to an antenna that allows access to stored data via radio frequency reading. As shown in Figure 2, the gas station 10 comprises cabinets or totem poles 3A, 13B, 3C, installed on the supply island 14 and comprising the necessary equipment for vehicle identification as well as for processing and completion. financial discharge operation.

 Preferably, the totems 13A, 13B, 13C are installed such that their faces are each facing one side of the supply island 14, allowing simultaneous servicing of both sides of the supply pump 15.

 On each of these faces are windows which allow, for example, the display of information on supply and financial operation.

 In a preferred embodiment, totems 13A, 13B, 13C have a door that can be kept closed by means of a security lock. This door allows access to the equipment installed inside for adjustments, cleaning and maintenance.

Preferably, totems 13A, 13B, 13C are a metal enclosure comprising equipment, cables and power and grounding features. In particular, totem poles 13A, 13B, 13C may be constructed of aluminum with epoxy paint finish.

 Figure 2 shows three models of totem poles 13A, 13B, 13C, which have distinct structures as follows:

 - The first totem model 13A is used when there is no furniture in front of the supply pump. Said totem 13A has a self-supporting structure without the aid of any other structure. Said first totem model 13A is fixed to the floor of the supply island 14 by means of parabolts, preferably at a distance of not less than 1 (one) meter from the supply pump 15.

- the second totem model 13B is installed in place of the product display cabinets on the supply island 14. The display cabinet must be in front (in the traffic direction) of the supply pump 15 using and consists of replacing the glass doors in the cabinets with hinged panels.

 The third totem model 13C is used when the front of the used pump 15 comprises a standard supply island end column structure 14. In this case, the pump facing panel is removed and replaced with a curved panel.

 Thus, as shown in Figure 2, each supply island 14 has at least one totem 13A, 13B, 13B responsible for operationalizing the system for automatic fueling payment using vehicle identification via an RFID fransponder.

 Since each totem 13A, 13B, 13B is responsible for a single supply island 14, there is no interference between simultaneous identification and payment processes performed via RFID transponders.

 Furthermore, as can be seen from Figure 3, totems 13A, 13B, 13C comprise: a central processing unit 20; RFID 21 readers, antennas 22A, 22B, video monitors 23A, 23B, video cameras 24A, 24B, a modem 25; an Ethernet Switch 26, operation override buttons 27A, 27B, power supplies 28, and connection cables.

 Thus, each totem 13A, 13B, 13C installed at gas station 10 contains its own RFID reader 21 and its own antennas 22A, 22B, which are dedicated to identification and payment processes performed on a single supply island.

 Also as can be seen in figure 3, the totem 13A, 13B, 13C may be connected to a non-fiscal printer 29 for the printing of cashier's cashier's proof of operation.

In addition, totem 13A, 13B, 13C may be connected to a second Ethernet Switch 30 for communication with the filling station automation system 34 for exchange of financial transaction information performed by this payment method, and, through the 32, you can connect to a Central 33 Online Authorizer, a Centra! 35 and a Remote Database 36. It should be noted that Central Online Authorizer 33, Supervisory Central 35 and Remote Database 36 are located outside the gas station 10.

In addition, the second Ethernet Switch 30 is also connected to the point of sale system (POS) 31 of supply island 14 via the communication link of the existing POS system 31 on island 14. The PDV 31 system issues invoices of sales to the consumer. Such sales may be made by any means of payment, such as cash, debit or credit cards, or automatic payment.

The central processing unit 20 has the function of controlling the communication and the local operation, accomplishing the following tasks:

 interfacing with the Radio Frequency reader 21, receiving the information from RFID transponders 11 read;

 - decrypt the read RFID transponders 1 1;

 interfacing with 24A, 24B video cameras that capture images of the fueling vehicle;

 - Interface with monitors 23A, 23B, to display messages and information regarding the filling process and about the financial settlement operation to keep the user and attendant abreast of all the steps involved;

 - interface with a station automation system 34 which provides information generated by the supply pumps, receiving information relating to the supply process, such as fuel type, nitriding and operation value;

 - perform the online authentication of the automatic operation through a consultation via internet connection of the station itself or through a modem 25, acting as a contingency of connection; and

- Perform diagnostic routines to verify the proper functioning of hardware and software components by displaying the routines on the video monitor 23A, 23B and transmitting to any Supervisory Center 35 any abnormalities found. Central Processing Unit 20 is further responsible for task management, monitoring of operations and supervision of activities performed,

 In addition, central processing unit 20 comprises a Message Manager Module, responsible for communicating with Centrai Online Authorizer 33 whether or not to authorize the operation in accordance with established business rules, and to control the discharge operation. payment of supplies. Generally speaking, the Message Manager Module works as follows:

It receives from RFID reader 21 the identification of RFID transponder 1 1 installed in the vehicle;

 Assembles and forwards a message to Centrai Online Authorizer 33 informing the identification of the RFID transponder 11 and waits for a reply message informing whether that RFID transponder 11 is authorized to perform the supply operation;

If so, it releases the payment transaction through the system for automatic payment of fuel to gas stations via RFID;

 [0039] At the end of the supply, it completes the operation by sending the transaction to a Remote Database 36 and triggers the sending of a text message (SMS) to the client informing the operation data.

In addition, central processing unit 20 further comprises a Test Routine Module which periodically checks and tests the equipment and services involved in the RFID supply payment process. Abnormality information is transmitted to Supervisory Center 35 for recovery measures to be taken.

In a preferred embodiment, the radio frequency identification reader 21 operates at a frequency of 915 MHz and an reading standard ISO / IEC 18000-63 connected to two 8.5 dbi antennas via 80 cm long coaxial cables, which allows installed transponders on vehicles that are in the reading area in the refueling position can be uniquely identified.

 Furthermore, due to the proximity of antenna 22A, 22B and transponder 11, the reading field should preferably be set to a minimum, allowing the power used to be reduced. For example, 1/3 of the power generally used in garage access control and shopping mall parking operation can be used, ie approximately 12 dBm, which is equivalent to 15.85mW of radiated power.

 [0043] RFID reader 21 is also responsible for capturing operation cancellation button actuation information 27A, 27B, one being arranged on either side of the supply island. When the cancel buttons 27A, 27B are pressed, it indicates that the user has requested the cancellation of the automatic payment via RFID operation, choosing to settle the supply by another payment method.

The cancel buttons 27A, 27B have multiple functions according to the moment they are activated, as follows:

Cancellation: During the interval between the supply authorization and the end of the operation, when the attendant replaces the nozzle on the pump, it is possible to cancel the payment operation via RFID transponder by pressing the button 27A, 27B on the side where the supply is being performed. During the interval where cancellation is possible, cancel button 27A, 27B is illuminated;

 [0046] Voucher duplicate printing: All the time the cancel button 27A, 27B is not illuminated, if pressed, the attendant's voucher related to the last operation performed on the side of the RFID-actuated button is reprinted;

[0047] Shift Closure Report Printing: If both 27A, 27B buttons on both sides of the totem are pressed simultaneously for more than three seconds, a shift closure report is printed, showing the operations performed and settled using the system RFID payment theme, since the last closing report was printed.

 Still as can be seen from figure 3, totems 13A, 13B, 13C comprise at least two video monitors 23A, 23B, one for each side of the supply island, so that two supply operations can be performed simultaneously. . In this case, the information displayed on each of the monitors 23A, 23B is independent of each other.

 Like monitors 23A, 23B, two video cameras 24A, 24B are arranged at totem 13A, 13B, 13C, one for each side of the supply island.

 Cameras 24A, 24B are equipped with motion picture capture technology and infrared illumination and are capable of capturing vehicle images at and near the fueling position and passing the image to the central processing unit. 20 .

 The central processing unit 20 temporarily stores the images on a storage medium during the supply process. At the end of the process, the images are transferred to Remote Database 36, where they are associated with the corresponding supply operation, and kept stored for a predetermined period, allowing further consultation in case of doubt or challenge by the user.

 If the connection to Central Online Authorizer 33 cannot be made via the Internet, communication may alternatively be via a modem connected to the central processing unit 20.

 In addition, Ethernet Switch 26 installed on totem 13A, 13B, 13C enables communication of all TCP-IP devices with central processing unit 20.

The central processing unit 20 further comprises a Decryption Module which receives the identification of the free transponders. RFID readers that are encrypted and, using key tables and specific decryption routines, "translates" the fransponder ID so that it can be referenced in an authorization table identifying the vehicle.

 [0055] The procedure for automatic fueling payment using an RFID reader installed on the fueling island basically comprises the following steps:

[0056] During the period when no fueling is performed with the system for automatic payment of fuel to petrol stations via RFID, the system is at rest.

When a vehicle carrying an identification RFID transponder is approaching the supply location, one of the video cameras located on the totem pole captures the front or rear image of the vehicle, depending on how the vehicle is approaching.

 It is important to note that the reading can be performed from both the front and rear of the vehicle, except for vehicles with metal buckets or which do not have a glazed area at the rear, as it would not be possible to read the transponder. through the rear window.

 [0059] The reader located on the totem reads RFID fransponder.

 [0060] The transponder is decrypted and the Central Processing Unit passes the translated ID to the Centrai Online Authorizer.

 [0061] The RFID transponder ID is analyzed and checked to see if the transponder is active and the forward account. You can also check other parameters, such as daily and monthly limits for the fill function.

If the authorization is approved, a supply authorization web with the registered vehicle data is displayed on the corresponding monitor installed on the totem, informing that the supply may be paid by the system of the present invention. It is evident that the steps listed above take place within a few seconds, so that when a vehicle is parked next to the supply pump, the entire process has already been performed and automatic operation availability information is already being displayed on the monitor.

In addition, if the data shown on the screen does not match the vehicle stationary at the pump, the filling can still be performed. If the discrepancy is found by the attendant, it can guide the driver to request the correction of the information.

At this point, the driver only needs to inform the attendant the type of fuel and the amount or amount to be filled.

Optionally, the driver may waive the payment of the supply automatically, opting for another form of payment. In this case, the attendant, when informed of this option, must press the cancel button on the totem.

By pressing the button, automatic RFID payment is canceled and this information is displayed on the corresponding monitor, alerting the driver that payment will not be made by the system of the present invention.

 It is noteworthy that the cancellation of the automatic operation can be performed from the moment the authorization of the operation is displayed until the end of the supply. During the entire period in which cancellation is possible, the illumination of the cancel button is activated.

[0069] If the driver chooses to continue automatic operation, when the pump is started, the pump sends an initial message identifying the pump, fuel type and zero value for the liter and for the sale value to the central processing unit. .

 If you do not receive from the pump this first message that ensures the pump is zeroed, the monitor displays an error message, preventing automatic payment from proceeding.

If you normally receive this start message, the pump will display the "supply in progress" message on the monitor. changing the supply evolution in real time, reproducing the information displayed on the pump's digital display,

 During the refueling process, a second image of the vehicle is recorded by the corresponding camera and sent to the central processing unit for storage,

 Upon completion of the supply operation, the pump sends a final supply message, including the litigation and final sale value. At this point, an information message of "Supply Complete" is displayed on the monitor, the liter and the final value,

The central processing unit then sends to the Remote Database data relating to the supply operation, including the supply fines and final amount to be paid, as well as additional information characterizing the supply operation. supply.

The supply operation is processed and the amount to be paid to the account associated with the RFID transponder present in the vehicle is authorized.

 [0076] It is also possible to send an SMS message to the registered user's mobile phone with the operation data.

When the transponder leaves the RF reading field, a third vehicle image is captured and transferred to the central processing unit.

 In the central processing unit, the captured images are renamed with the supply transaction encoding, associating them with the operation that was just performed for storage in the Remote Database.

Note that whenever a supply is identified without the use of RFID transponders, an end-of-operation record associated with the license plate number obtained from the vehicle license plate image OCR can be recorded. This record can be accumulated locally for the purpose of building a database of potential customers. In addition, if during the authorization process communication with the Central Online Authorizer is not possible, an error screen is displayed until communication is reestablished.

 It is important to point out that the information regarding the supply (fuel type, nitriding and value) is obtained directly from the supply pump, avoiding manual entry of this information by the attendant.

 Having described a preferred embodiment example, it should be understood that the scope of the present invention encompasses other possible variations, being limited only by the content of the appended claims, including the possible equivalents.
