Abstract

A computing device receives a first digital signal from a data acquisition system. It is determined that a first value includes in the first signal indicates an event. A second digital signal is received from the data acquisition system. It is determined that a second value included in the second signal includes a value that indicates the event, and that the event has occurred based at least in part on the first value, the second value, and a passage of a predetermined duration of time between a time of the first digital signal and a time of the second digital signal.

Claims

1. A system, comprising a computing device that includes a processor and a memory, wherein the computing device is configured to:

receive a first digital signal from a data acquisition system;

determine that a first value included in the first signal indicates an event;

receive a second digital signal from the data acquisition system;

determine that a second value included in the second signal includes a value that indicates the event;

determine that the event has occurred based at least in part on the first value, the second value, and a passage of a predetermined duration of time between a time of the first digital signal and a time of the second digital signal.

2. The system of claim 1, wherein the computing device is further configured to receive at least one third digital signal between the time of the first digital signal and the time of the second digital signal.

3. The system of claim 1, wherein the computing device is further configured to record the time of the first digital signal as the event start time and the time of the second digital signal as the event end time.

4. The system of claim 1, wherein the computing device is further configured to provide event data to a fact stack of a rules engine.

5. The system of claim 4, wherein the computing device is further configured to provide the event data in a message sent via a network.

6. The system of claim 5, further comprising a second computer that is configured to receive the message via the network.

7. The system of claim 1, wherein the computing device is further configured to receive a third digital signal from a second data acquisition system, the third digital signal including data indicating a status of a component being monitored by the second data acquisition system.

8. A method, comprising:

receiving, in a computing device, a first digital signal from a data acquisition system;

determining that a first value included in the first signal indicates an event;

receiving a second digital signal from the data acquisition system;

determining that a second value included in the second signal includes a value that indicates the event;

determining that the event has occurred based at least in part on the first value, the second value, and a passage of a predetermined duration of time between a time of the first digital signal and a time of the second digital signal.

9. The method of claim 8, further comprising receiving at least one third digital signal between the time of the first digital signal and the time of the second digital signal.

10. The method of claim 8, further comprising recording the time of the first digital signal as the event start time and the time of the second digital signal as the event end time.

11. The method of claim 8, further comprising providing event data to a fact stack of a rules engine.

12. The method of claim 11, further comprising providing the event data in a message sent via a network.

13. The method of claim 12, further comprising receiving the message via the network in a second computing device.

14. The method of claim 8, further comprising receiving a third digital signal from a second data acquisition system, the third digital signal including data indicating a status of a component being monitored by the second data acquisition system.

15. A system, comprising a computing device that includes a processor and a memory, wherein the computing device is configured to:

receive a first digital signal from a data acquisition system;

determine that a first value included in the first signal indicates an event;

identify a start time for the event;

identify and end time for the event; and

provide the event to a fact stack of a rules engine.

16. The system of claim 15, the computing device further configured to receive at least one second digital signal including a second value, and to include the second value in the event.

17. The system of claim 16, the computing device further configured to record the time of the first digital signal as the event start time and the time of the second digital signal as the event end time.

18. The system of claim 16, the computing device further configured to provide event data to the fact stack of the rules engine only after the event end time has been recorded.

19. The system of claim 15, the computing device further configured to provide the event data in a message sent via a network.

20. The system of claim 16, computing device further configured to receive a third digital signal from a second data acquisition system, the third digital signal including data indicating a status of a component being monitored by the second data acquisition system.
