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, at a remote server, navigational reports associated with at least two vessels;

decoding, by the remote server, the navigational reports into a form for display and analysis;

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

determining, by the remote server, a brushing incident by detecting an intersection of the domains of the two vessels along the trajectories; and

in response to determining a number of brushing incidents exceeding a predetermined maximum number, wirelessly transmitting , by the remote server, a report of the brushing incidents to one or more mobile devices remote from the server and the at least two vessels.

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

receiving at a remote server, from multiple data sources, data associated with one or more moving objects;

decoding, by the remote server, the data into a form for display and analysis;

determining, by the remote server, one or more constraints associated with an event-of-interest;

determining, by the remote server based on the data, the event-of-interest that satisfies the one or more constraints;

optimizing, by the remote server and based on the determined event-of-interest, port operations including determining an optimized time, route or place for berthing one or more vessels; and

wirelessly sending a notification of the determined event-of-interest to one or more mobile devices remote from the server and the one or more moving objects.

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 determining the event-of-interest that satisfies the one or more constraints comprises determining 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 determined event-of-interest and transmitting text or graphical updates to the one or more mobile devices.

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

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

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

12. The computer-implemented method of claim 2 wherein determining the event-of-interest that satisfies the one or more constraints comprises determining 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 from a user, via a user interface of the one or more mobile devices, 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 determining the event-of-interest that satisfies the one or more constraints comprises determining a flag violation event.

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

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 determined event-of-interest comprises displaying, on a map, the notification that indicates a location of the determined event-of-interest.

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