Abstract

An alarm trigger communicating system and methods of using the same are provided. The alarm trigger communicating system can receive data characterizing an operational state of a machine and a timing information associated with the operational state. The system can access, based on the operational state, an alarm trigger of a plurality of alarm triggers, the alarm trigger can include predefined properties including an alarm threshold. The system can also display a graphical object representing the alarm trigger, the graphical object displayed in a graphical display space can have a first axis and a second axis for displaying a plot over time of operational parameter associated with the machine. The graphical object having a first visual characteristic can indicate the alarm threshold.

Claims

1. A method comprising:

receiving data characterizing an operational state of a machine and an associated timing information;

accessing, based on the operational state, an alarm trigger of a plurality of alarm triggers, the alarm trigger including predefined properties including an alarm threshold value; and

displaying a graphical object representing the alarm trigger, the graphical object displayed in a graphical display space having a first axis and a second axis for displaying a plot over time of an operational parameter associated with the machine, the graphical object having a first visual characteristic indicating the alarm threshold,

wherein the graphical object comprises;

a first triangle; and

a second triangle connected by a line to the first triangle, an edge of the first triangle, an edge of the second triangle and the line oriented parallel to the first axis.

2. The method in claim 1, wherein the associated timing information includes a duration of the operational state, the duration represented by a length of the graphical object.

3. The method in claim 1, wherein the associated timing information includes a time of start of the operational state represented by a position of a leading vertex of the graphical object.

4. The method in claim 1, wherein the first visual characteristic comprises a color of at least a portion of the graphical object;

or a position of the graphical object along the second axis.

5. The method in claim 1, wherein the predetermined properties comprise an alarm type including an over alarm type, an under alarm type, and an out of band alarm type.

6. The method in claim 5, wherein the graphical object oriented upwards represents the alarm trigger having an over alarm type.

7. The method in claim 5, wherein the graphical object oriented downwards represents the alarm trigger having an under alarm type.

8. The method in claim 5, wherein the graphical object oriented downward combined with the graphical object oriented upwards represents an alarm trigger having the out of band alarm type.

9. The method in claim 1, wherein the predefined properties of the alarm trigger comprise an alarm status including a current alarm status and a historic alarm status.

10. The method in claim 9, wherein the graphical object comprising the first and the second triangle characterized by a single color represents the current alarm status.

11. The method in claim 9, wherein the graphical object comprising the first and the second triangle characterized by a plurality of colors represents the historic alarm status.

12. The method in claim 1, wherein the predefined properties of the alarm trigger comprise an alarm source including a device protection source and a condition monitoring source.

13. The method in claim 12, wherein the graphical object comprising the line characterized by a thickness greater than a first predetermined thickness represents the device protection source.

14. The method in claim 12, wherein the graphical object comprising the line characterized by a thickness less than a second predetermined thickness represents the condition monitoring source.

15. The method of claim 1, wherein the predefined properties of the alarm trigger comprises an alarm activity including active alarm activity and suppressed alarm activity.

16. The method in claim 15, wherein the graphical object comprises a solid line representing the active alarm activity.

17. The method in claim 15, wherein the graphical object comprises a dashed line representing the suppressed alarm activity.

18. The method in claim 1, further comprising receiving data representative of the operational parameter from a sensor.

19. The method in claim 1, wherein the operational state comprises one of start-up state, steady operation state, shut-down state, slow roll state or machine roll state.

20.

21. The method of claim 1, further comprising:

accessing, based on the operational state, multiple alarm triggers of the plurality of alarm triggers, each of the multiple alarm triggers comprising predefined properties comprising an alarm threshold value; and

displaying a graphical object for each of the multiple alarm triggers, the graphical object for each of the multiple alarm triggers displayed in the graphical display space.

22. The method of claim 1 further comprising:

receiving data characterizing an another operational state of the machine and an associated timing information;

accessing, based on the another operational state, an another alarm trigger of the plurality of alarm triggers, the another alarm trigger comprising predefined properties comprising an another alarm threshold; and

displaying an another graphical object representing the second alarm trigger, the another graphical object displayed in the graphical display space, the another graphical object having a visual characteristic indicating the second alarm threshold.

23. A non-transitory computer readable medium storing instructions, which when executed by at least one data processor forming part of at least one computing system causes the at least one data processor to perform operations that comprise:

receive data characterizing an operational state of a machine and an associated timing information;

access, based on the operational state, an alarm trigger of a plurality of alarm triggers, the alarm trigger comprising predefined properties comprising an alarm threshold; and

display a graphical object representing the alarm trigger, the graphical object displayed in a graphical display space having a first axis and a second axis for displaying a plot over time of operational parameter associated with the machine, the graphical object having a first visual characteristic indicating the alarm threshold,

wherein the graphical object comprises;

a first triangle; and

a second triangle connected by a line to the first triangle, an edge of the first triangle, an edge of the second triangle and the line oriented parallel to the first axis.
