Abstract

An alarm trend summary display system and method can utilize an alarm trend list that works together with an alarm summary list. A set of rows in the alarm trend list can be organized in a top-to-bottom manner. A set of alarm indicators within each row in the alarm trend list can be arranged in a right-to-left horizontal arrangement. The set of alarm indicators can be aligned with most recent alarms appearing on a right side of the alarm trend list. The specific alarm indicators can be selected in the alarm trend list, so that a corresponding item can be highlighted in the alarm summary list, if the alarms are active. Hence, the system and method can allow an operator to see when alarms occur, their sequence, relations and priority, which aid the operators cope with inevitable alarm floods.

Claims

1. A prioritized alarm trend summary display method operating on a computer, comprising:

graphically displaying a prioritized alarm trend list in conjunction with a prioritized alarm summary list with a plurality of highlighting and filtering functions, and organizing a plurality of rows in said prioritized alarm trend list in a top-to-bottom manner;

prioritizing a plurality of alarm indicators over time within said plurality of rows in said prioritized alarm trend list in a right-to-left horizontal arrangement with qualitative trend arrows indicating a qualitative direction of a parameter that last alarmed in said plurality of rows in said alarm trend list

aligning said plurality of prioritized alarm indicators with a most recent real-time alarm appearing on a right side of said prioritized alarm trend list and a historical representation of said plurality of alarm indicators appearing on a left side of said prioritized alarm trend list, said plurality of prioritized alarm indicators organized logically by location so that said plurality of prioritized alarm indicators are scalable to any level in equipment hierarchy; and

selecting at least one of said plurality of prioritized alarm indicators in said prioritized alarm trend list, so that a corresponding alarm description item is highlighted and displayed in said alarm summary list, if said alarm is active, thereby allowing an operator to see when said alarm occur, their sequence, relation and priority, which helps said operator cope with an inevitable alarm flood.

2. The method of claim 1 further comprising:

displaying a complete alarm description with a tag name in a tool tip field in said alarm trend list, when a mouse is pointed over said plurality of alarm indicators in said alarm trend list.

3. The method of claim 1 wherein said plurality of rows comprises a gray band, a color choice and a font style/size.

4. The method of claim 1 wherein said alarm trend list comprises at least two or three rows per location.

5. The method of claim 1 wherein said plurality of alarm indicators on a left side of a black line in said alarm trend list is a historical representation and on a right side of said black line in said alarm trend list is a real-time representation.

6. The method of claim 1 wherein said tag name comprises a current point value and a deviation from set point.

7. The method of claim 1 wherein said alarm trend list also comprises an alarm type that is embedded in an alarm priority symbol.

12. The method of claim 1 wherein said tag name comprises a current point value and a deviation from set point.

13. The method of claim 1 wherein said alarm trend list also comprises an alarm type that is embedded in an alarm priority symbol.

8. A prioritized alarm trend summary display method operating on a computer, comprising:

graphically displaying a prioritized alarm trend list in conjunction with a prioritized alarm summary list with a plurality of highlighting and filtering functions, and organizing a plurality of rows in said prioritized alarm trend list in a top-to-bottom manner;

prioritizing a plurality of alarm indicators over time within said plurality of rows in said prioritized alarm trend list in a right-to-left horizontal arrangement with qualitative trend arrows indicating a qualitative direction of a parameter that last alarmed in said plurality of rows in said alarm trend list

aligning said plurality of prioritized alarm indicators with a most recent real-time alarm appearing on a right side of said prioritized alarm trend list and a historical representation of said plurality of prioritized alarm indicators appearing on a left side of said prioritized alarm trend list, said plurality of prioritized alarm indicators organized logically by location so that said plurality of prioritized alarm indicators are scalable to any level in equipment hierarchy;

displaying a complete alarm description with a tag name in a tool tip field in said alarm trend list, when a mouse is pointed over said plurality of alarm indicators in said alarm trend list; and

selecting at least one of said plurality of alarm indicators in said alarm trend list, so that a corresponding alarm description item is highlighted and displayed in said alarm summary list, if said alarm is active, thereby allowing an operator to see when said alarm occur, their sequence, relation and priority, which helps said operator cope with an inevitable alarm flood.

9. The method of claim 8 wherein said plurality of rows comprises a gray band, a color choice and a font style/size.

10. The method of claim 8 wherein said alarm trend list comprises at least two or three rows per location.

11. The method of claim 8 wherein said plurality of alarm indicators on a left side of a black line in said alarm trend list is a historical representation and on a right side of said black line in said alarm trend list is a real-time representation.

14. A alarm monitoring system including a prioritized trend summary display, comprising:

a computer;

a graphical display connected to said computer and configured to graphically displaying a prioritized alarm trend list in conjunction with a prioritized alarm summary list with a plurality of highlighting and filtering functions, and organizing a plurality of rows in said prioritized alarm trend list in a top-to-bottom manner;

an alarm trend summary software operating within said computer and configured to prioritize a plurality of alarm indicators over time within said plurality of rows in said alarm trend list in a right-to-left horizontal arrangement with qualitative trend arrows indicating a qualitative direction of a parameter that last alarmed in said plurality of rows in said prioritized alarm trend list

aligning said plurality of prioritized alarm indicators with a most recent real-time alarm appearing on a right side of said alarm trend list and a historical representation of said plurality of prioritized alarm indicators appearing on a left side of said alarm trend list, said plurality of prioritized alarm indicators organized logically by location so that said plurality of prioritized alarm indicators are scalable to any level in equipment hierarchy;

a display connected to said computer and configured to displaying a complete alarm description with a tag name in a tool tip field in said alarm trend list, when a mouse is pointed over said plurality of alarm indicators in said prioritized alarm trend list; and

a user interface configured to enable a user to select at least one of said plurality of prioritized alarm indicators in said alarm trend list, so that a corresponding alarm description item is highlighted and displayed in said prioritized alarm summary list, if said alarm is active, thereby allowing an operator to see when said alarm occur, their sequence, relation and priority, which helps said operator cope with an inevitable alarm flood.
