Unreported event status change determination and alerting

摘要

In a method for determining an unreported event status change for an asset, an asset management system receives a position of an asset from a reporting source coupled with the asset. The position is associated with a particular time by the reporting source. The position is compared to a previous position of the asset, the previous position being associated with a previous time that is earlier than the particular time. Based upon the comparing of the position to the previous position, it is determined if an unreported event status change has occurred for the asset.

主权项

1. A method for determining an unreported event status change for an asset within a computer-based asset management system, the asset management system including a data receiver, a database, a processor, and an alert trigger service, the method comprising:
receiving at the data receiver a first event status of the asset from a wireless reporting source coupled with the asset, the first event status being a most recently received reported event status and indicating that the asset is stationary; storing the first event status as a maintained event status of the asset in the database: receiving at the data receiver a first position of the asset from the wireless reporting source at a first time; receiving at the data receiver a second position of the asset from the wireless reporting source at a second time while the reporting source is in a power conservation operating mode, the second time being later than the first time; determining at the processor a second event status of the asset indicating that the asset is moving based on a distance between the second position and the first position and a time difference between the second time and the first time; determining at the processor that the second event status is different from the first event status by comparing the second event status and the first event status; in response to determining that the second event status is different from the first event status, determining at the processor that the difference is due to a failure to receive an updated event status of the asset from the wireless reporting source: and issuing through the alert trigger service a status alert regarding the asset in response to determining that second event status satisfies a pre-defined alert reporting criterion.
