Abstract

Various methods, systems, and device are provided for facilitating communication between a fuel dispenser and a forecourt controller. In some embodiments, the methods, systems, and devices allow data to be combined and compressed for transmission through a reduced number of data connections, and then decompressed for transmission to the forecourt controller or components of the fuel dispenser. In certain exemplary embodiments, the compressing and decompressing can be performed by one or more signal combiners at the forecourt controller and the fuel dispenser.

First claim

What is claimed is:

1. A processing system comprising:
a forecourt signal combiner connected to a forecourt controller by a first pair of wires and a second pair of wires, the forecourt signal combiner configured to receive forecourt payment command signals from the forecourt controller via the first pair of wires and forecourt fuel controller signals from the forecourt controller via the second pair of wires, and to combine and compress the forecourt payment command signals and forecourt fuel controller signals to form forecourt compressed data;
a fuel dispenser signal combiner connected to a payment terminal in a fuel dispenser by a third pair of wires and to a fuel controller in the fuel dispenser by a fourth pair of wires, the fuel dispenser signal combiner configured to receive fuel dispenser payment command signals from the payment terminal via the third pair of wires and fuel dispenser fuel controller signals from the fuel controller via the fourth pair of wires, and to combine and compress the received fuel dispenser payment command signals and fuel dispenser fuel controller signals to form fuel dispenser compressed data, the third pair of wires being dedicated for transmission of the fuel dispenser payment command signals;
wherein the forecourt signal combiner is configured to transmit the forecourt compressed data to the fuel dispenser signal combiner, and to receive the fuel dispenser compressed data transmitted by the fuel dispenser signal combiner; and
wherein the fuel dispenser signal combiner is configured to transmit the fuel dispenser compressed data to the forecourt signal combiner, and to receive the forecourt compressed data transmitted by the forecourt signal combiner.

2. The processing system of claim 1 , wherein the forecourt signal combiner is configured to decompress the compressed data received from the fuel dispenser signal combiner, and the fuel dispenser signal combiner is configured to decompress the compressed data received from the forecourt signal combiner.

3. The processing system of claim 1 , further comprising a fuel controller translator configured to perform operations comprising:
receiving a fuel command having a first format;
translating the fuel command from the first format to a second format; and
transmitting the fuel command in the second format.

4. The processing system of claim 3 , wherein the fuel controller translator is connected in series between the forecourt signal combiner and the fuel dispenser signal combiner.

5. The processing system of claim 3 , wherein the forecourt signal combiner includes the fuel controller translator.

6. The processing system of claim 3 , wherein the forecourt signal combiner and the fuel dispenser signal combiner are in communication over two data channels.

7. The processing system of claim 1 , further comprising:
a server configured to be in communication with a client, wherein the server and the client are configured to provide a TCP/IP connection between the forecourt controller and the fuel dispenser.

8. The processing system of claim 7 , wherein the server and the client are connected in series between the forecourt signal combiner and the fuel dispenser signal combiner and wherein the communication between the server and the client use the same data channels as the data signal.

9. The processing system of claim 1 , wherein the third pair of wires is not coupled to the fuel controller and is thus prevented from transmitting any fuel dispenser fuel controller signals to the fuel controller, and the fourth pair of wires is not coupled to the payment terminal and is thus prevented from transmitting any payment command signals to the payment terminal.

10. A communication method for a fuel dispenser, comprising:
at a fuel dispenser, receiving a compressed data signal from an external source over first and second wires;
at the fuel dispenser, decompressing the compressed data signal into a payment command for processing a payment for fuel and a fuel command for controlling dispensing of fuel from the fuel dispenser;
transmitting the payment command via third and fourth wires to a payment terminal at the fuel dispenser so as to cause the payment terminal to execute the payment command, the third and fourth wires being dedicated for transmission of the payment command; and
transmitting the fuel command via fifth and sixth wires to a fuel controller at the fuel dispenser so as to cause the fuel controller to execute the fuel command.

11. The method of claim 10 , further comprising, at the fuel dispenser, receiving a payment command for processing a payment for fuel and a fuel command for controlling dispensing of fuel from the fuel dispenser, and compressing the payment command and fuel command to form a second compressed data signal, and transmitting the second compressed data signal over the first and second wires.

12. The method of claim 10 , wherein a signal combiner at the fuel dispenser decompresses the compressed data signal.

13. The method of claim 10 , wherein the external source includes a forecourt controller, and the compressed data signal is transmitted to the fuel dispenser by a signal combiner coupled between the forecourt controller and the fuel dispenser.

14. The method of claim 13 , wherein the signal combiner coupled between the forecourt controller and the fuel dispenser receives a payment command and a fuel command from the forecourt controller, and compresses the payment command and fuel command to create the compressed data signal that is received at the fuel dispenser.

15. The method of claim 10 , wherein the third and fourth wires are not coupled to the fuel controller and are thus unable to carry any signals to the fuel controller, and the fifth and sixth wires are not coupled to the payment terminal and are thus unable to carry any signals to the payment terminal.

16. A method for modifying a fuel dispenser, comprising:
installing a forecourt signal combiner such that the forecourt signal combiner is coupled to a forecourt controller by a first pair of wires for receiving forecourt payment data and by a second pair of wires for receiving forecourt fuel command data, and such that the forecourt signal combiner is coupled to a first end of two underground wires; and
installing a fuel dispenser signal combiner in a fuel dispenser such that the fuel dispenser signal combiner is coupled to a second end of the two underground wires, and the fuel dispenser signal combiner is coupled to a payment terminal in a fuel dispenser by a third pair of wires for receiving fuel dispenser payment data and is coupled to a fuel controller in the fuel dispenser by a fourth pair of wires for receiving fuel dispenser fuel controller data, the third pair of wires not being coupled to the fuel controller and thus being unable to transmit the fuel dispenser fuel controller data, and the fourth pair of wires not being coupled to the payment terminal and thus being unable to transmit the fuel dispenser payment data;
wherein the forecourt signal combiner is configured to compress the forecourt payment data and the forecourt fuel command data for transmission through the two underground wires to the fuel dispenser signal combiner; and
wherein the fuel dispenser signal combiner is configured to compress the fuel dispenser payment data and the fuel dispenser fuel controller data for transmission through the two underground wires to the forecourt signal combiner.

17. The method of claim 16 , wherein the forecourt signal combiner is configured to decompress the compressed data received from the fuel disp
