Abstract

Described herein is a technology for facilitating complex event processing for moving objects. In some implementations, data associated with moving objects is received from multiple data sources. One or more constraints associated with an event-of-interest are determined. The event-of-interest that satisfies the one or more constraints is detected based on the data. A notification of the detected event-of-interest may then be sent. For purposes of illustration, some specific complex event processing scenarios based on maritime vessels have been presented to demonstrate the capabilities of the present framework.

Claims

1. A computer-implemented method of detecting a constant brushing event comprising:

receiving navigational reports associated with at least two vessels;

computing, based on the navigational reports, a domain and a trajectory for each of the two vessels; and

determining a brushing incident by detecting an intersection of the domains of the two vessels along the trajectories.

2. A computer-implemented method of complex event processing comprising:

receiving, from multiple data sources, data associated with one or more moving objects;

determining one or more constraints associated with an event-of-interest;

detecting, based on the data, the event-of-interest that satisfies the one or more constraints; and

sending a notification of the detected event-of-interest.

3. The computer-implemented method of claim 2 further comprising storing the data in an in-memory database.

4. The computer-implemented method of claim 2 wherein receiving the data associated with the one or more moving objects comprises receiving live data from at least one automatic identification system (AIS) receiver.

5. The computer-implemented method of claim 2 wherein receiving the data associated with the one or more moving objects comprises receiving data from an Internet server source.

6. The computer-implemented method of claim 2 wherein receiving the data associated with the one or more moving objects comprises receiving hydrological or meteorological data.

7. The computer-implemented method of claim 2 wherein detecting the event-of-interest that satisfies the one or more constraints comprises detecting an event-of-interest that is a precursor to one or more incidents that are likely to occur in the absence of a preventive measure.

8. The computer-implemented method of claim 2 further comprising tracking a status of the detected event-of-interest.

9. The computer-implemented method of claim 2 wherein sending the notification of the detected event-of-interest comprises sending a maritime intelligence report that identifies one or more vessels involved in the detected event-of-interest.

10. The computer-implemented method of claim 2 further comprising sending the notification of the detected event-of-interest to a port operations system.

11. The computer-implemented method of claim 2 further comprising sending the notification of the detected event-of-interest to a logistics operations system.

12. The computer-implemented method of claim 2 wherein detecting the event-of-interest that satisfies the one or more constraints comprises detecting a restricted zone violation event.

13. The computer-implemented method of claim 12 wherein determining the one or more constraints associated with the event-of-interest comprises receiving, via a user interface, user input that specifies an access control policy, wherein the access control policy designates a specific area as a restricted zone.

14. The computer-implemented method of claim 2 wherein detecting the event-of-interest that satisfies the one or more constraints comprises detecting a flag violation event.

15. The computer-implemented method of claim 2 wherein detecting the event-of-interest that satisfies the one or more constraints comprises detecting a constant brushing event.

16. The computer-implemented method of claim 2 wherein determining the one or more constraints associated with the event-of-interest comprises receiving, via a user interface, user input that defines the one or more constraints.

17. The computer-implemented method of claim 2 wherein determining the one or more constraints associated with the event-of-interest comprises automatically retrieving, from an in-memory database, the one or more constraints.

18. The computer-implemented method of claim 2 wherein sending the notification of the detected event-of-interest comprises displaying, on a map, the notification that indicates a location of the detected event-of-interest.

19. A non-transitory computer-readable medium having stored thereon program code, the program code executable by a processor to:

receive, from multiple data sources, data associated with moving objects;

determine one or more constraints associated with an event-of-interest;

detect, based on the data, the event-of-interest that satisfies the one or more constraints; and

send a notification of the detected event-of-interest.

20. A complex event processing system comprising:

a non-transitory memory device for storing computer-readable program code; and

a processor in communication with the memory device, the processor being operative with the computer-readable program code to;

receive, from multiple data sources, data associated with moving objects;

determine one or more constraints associated with an event-of-interest;

detect, based on the data, the event-of-interest that satisfies the one or more constraints; and

send a notification of the detected event-of-interest.
