System and method for identifying related events in a resource network monitoring system
DCFirst Claim
1. A computerized method performed using a processor for identifying related events in a water network monitoring system, the events represented by stored event data derived from data received from one or more sources including sensor data received from a plurality of sensors in the water network, each event data comprising data identifying an event and one or more characteristics of the event, the method comprising:
- retrieving event data from an event database, the event data representing a plurality of events which have been processed from anomalies received from the water network monitoring system and which each contain a plurality of data fields including event start time and event magnitude;
identifying at least two events from the event data as being candidate events that are likely to constitute parts of a composite event, the identified candidate events each being determined by the water network monitoring system not to be statistically significant enough to be reported as events by themselves;
selecting an event combination rule, the event combination rule including one or more tests to determine whether the candidate events are related and can be combined to form a composite event of a given event type;
comparing one or more event characteristics between the at least two candidate events based on the event combination rule;
determining, based at least in part on the comparison, that at least two candidate events are related to one another and are processible as a single event of the given event type; and
reporting the determination of the at least two candidate events as being related and as the single event of the given event type to a user via a user interface.

Abstract
A computerized method for detecting related events in a water monitoring system. The method includes receiving event data from a plurality of sensors in a water network. The method also includes identifying at least two candidate events from the event data as being candidate events which are likely to constitute part of a common anomaly event, the candidate events each being substantially anomalous. An event combination rule is selected. One or more event characteristics are compared between the at least two candidate events based on the event combination rule. The at least two candidate events are determined whether they are related and associated with a common event causing the at least two candidate events on the basis of the comparison. The determination of the at least two candidate events are related and associated with a common event is reported to a user via a user interface.
