Abstract
The present invention relates to a fuel dispenser control system used in combination with a host computer for controlling the fuel dispensing process, and with newer dispensers, for accepting payment by credit card or cash dispenser. The fuel control system includes a fuel controller application installed on the operating system of the computer, and includes a host application interface, a fuel dispenser control section, and a fuel dispenser brand specific section. The system includes an OLE-II server, residing in the host computer, for receiving and processing commands from the host application section. The host application interface interfaces the fuel controller application to the host computer, the fuel dispenser control section controls the dispensers, and the dispenser brand specific section formats the communication signals according to the type dispenser being controlled. The fuel controller application communicates with the fuel dispensers through a dispenser distribution box by either standard serial communication or Ethernet circuitry for controlling the dispensers and receiving responses from the dispensers.

8. A method for controlling the fuel dispensing process by a fuel dispenser control system used in combination with at least one fuel dispenser having a pump means and a host computer including a fuel controller application means interfaced to the operating system of said computer for controlling said fuel dispensers and for formatting command and response data between said dispensers and said host computer and a dispenser distribution means functionally connecting said dispensers and said fuel controller application means for translating and adjusting command and response data between dispensers and said fuel controller application means, comprising the steps of:
-
(a) initializing on power up a TCP/IP Ethernet connection from said fuel controller application;
(b) sending data from said fuel controller application to configure the serial port used to communicate with said fuel dispensers, followed by an ACK signal back to said fuel controller application indicating the operation is complete;
(c) sending data from said fuel controller application to set or reset the control signal of said dispenser distribution box, followed by an ACK signal to said fuel controller application to indicate the operation is complete; and
(d) sending data from said fuel controller application to said dispensers and sending data from said dispensers back to said fuel controller application.
