Abstract

A monitoring system that permits an operator to observe on a visual display operating data for a plurality of dispensing devices. These data displays are visual representations based on signals received from a monitor control. The operator is able to arrange and group the displays of a plurality of dispensing devices as required. In one embodiment, the visual representations include graphical representations of a characteristic of the dispensed fluid on a time line, such as a pressure reading for example. Such graphical representations may include alarm limits or bands. Each visual representation may include fault indications that are time and date stamped. The visual representations may also be color coded to indicate normal and fault conditions. All of this monitoring may conveniently be performed at a location that is remote from the dispensing devices. The collected information may be logged for later analysis such as exporting the data to another program such as a spreadsheet database.

Claims

1. A system for monitoring a fluid dispensing apparatus, comprising:

a plurality of fluid dispensing devices;

a control device for controlling individually at least one operating parameter of each said dispensing devices;

a monitor control for individually monitoring a characteristic of fluid flow through each said dispensing device and producing a respective signal representative thereof;

a visual display; and

a display control that is coupled to said monitor control and receives said respective signals from said monitor control related to each said characteristic for each dispensing device;

said display control providing a respective visual representation of said characteristic for each said dispensing device;

said visual representations being displayed in selectable groupings on said visual display to permit an operator to monitor operation of said dispensing devices.

2. The system of claim 1 wherein said display control is coupled to said monitor control across a network to permit an operator to monitor operation of said dispensing devices from a remote location.

3. The system of claim 1 wherein each said visual representation comprises a graphical representation of each said signal relative to a time line.

4. The system of claim 1 wherein each said visual representation includes a color code to distinguish normal and fault conditions of each dispensing device.

5. The system of claim 1 wherein each said visual representation comprises a graphical representation of each said signal relative to a time line and a visual display of alarm limits for each signal.

6. The system of claim 5 wherein said alarm limits are graphically displayed as warning and fault bands on a time line.

7. The system of claim 1 wherein each said visual representation comprises data representations of each said characteristic, each said data representation being visually associated with a respective dispensing device graphic on said visual display.

8. The system of claim 1 wherein said signals are stored and can be later graphically displayed in a selected manner by an operator.

9. The system of claim 1 wherein said signals are date and time stamped.

10. The system of claim 1 wherein said display control compares said signals with respective limits and generates fault signals when a fault is detected;

each said detected fault being date and time stamped and separately displayable on said visual display.

11. A system for monitoring a fluid dispensing apparatus, comprising:

a plurality of fluid dispensing devices;

control means for controlling individually at least one operating parameter of each said dispensing devices;

monitor means for individually monitoring a characteristic of fluid flow through each said dispensing device and producing a respective signal representative thereof;

a visual display; and

a display control means that is coupled to said monitor means and receives said respective signals from said monitor means related to each said characteristic for each dispensing device;

said display device providing a respective visual representation of said characteristic for each said dispensing device;

said visual representations being displayed in selectable groupings on said visual display to permit an operator to monitor operation of said dispensing devices.

12. A method for monitoring a fluid dispensing apparatus, comprising the steps of:

operating a plurality of fluid dispensing devices;

individually controlling at least one operating parameter of each said dispensing devices;

individually monitoring a characteristic of fluid flow through each said dispensing device and producing a respective signal representative thereof; and

visually displaying a respective visual representation of said characteristic for each said dispensing device;

said visual representations being displayed in selectable groupings on a visual display to permit an operator to monitor operation of said dispensing devices.

13. The method of claim 12 wherein said visual representations comprise a graphical display of each said signal on a time line with alarm bands.

14. The method of claim 13 comprising the step of date and time stamping fault occurrences and visually displaying fault occurrences for each dispensing device.

15. A method for monitoring a fluid dispensing apparatus, comprising the steps of:

operating a plurality of fluid dispensing devices;

individually monitoring a characteristic of fluid flow through each said dispensing device and producing a respective signal representative thereof; and

visually displaying a respective visual representation of said characteristic for each said dispensing device;

said visual representations being displayed in selectable groupings on a visual display to permit an operator to monitor operation of a plurality of said dispensing devices on a single display screen.

16. The method of claim 15 wherein said visual representations comprise a graphical display of each said signal on a time line with alarm bands.

17. The method of claim 15 comprising the step of date and time stamping fault occurrences and visually displaying fault occurrences for each dispensing device.

18. The method of claim 15 wherein said visual representations are color coded to distinguish normal and fault conditions of each dispensing device.
