Selective reporting of events in asset tracking system
First Claim
Patent Images
1. A method comprising:
- entering an event masking parameter into a server computer;
generating an event masking rule based at least in part on the entered event masking parameter;
downloading the event masking rule from the server computer to an asset tracking unit;
detecting an event, said detecting occurring at the asset tracking unit; and
determining at the asset tracking unit, based at least in part on the downloaded event masking rule, whether to report the detected event;
wherein the detected event is at least one of;
coupling to a truck tractor of a truck trailer to which the asset tracking unit is attached; and
de-coupling from a truck tractor of a truck trailer to which the asset tracking unit is attached.

Abstract
In GPS based and other types of asset tracking system, event masking rules may be applied at asset tracking units and/or at a central station to determine whether to report events detected by the asset tracking units. The events may pertain to transportation vehicles such as truck trailers or cargo containers to which the asset tracking units are attached. The event masking rules may be defined at the central station and downloaded by satellite communication to the asset tracking units and/or the rules may be defined locally, at the asset tracking units.

8. A method comprising:
-
providing an asset tracking unit that is attached to a transportation vehicle; detecting an event that is related to the transportation vehicle, said detecting occurring at the asset tracking unit; and determining, based at least in part on an event masking rule, whether to report the detected event; wherein the detected event is at least one of;
coupling of the transportation vehicle to a truck tractor; and
de-coupling of the transportation vehicle from a truck tractor. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method comprising:
-
providing an asset tracking unit that is attached to a truck trailer; detecting an event in which the truck trailer is coupled to a truck tractor; and reporting that the truck trailer has been coupled to the truck tractor only if the asset tracking unit detects that the truck trailer is moved by at least a predetermined distance after the asset tracking unit detects that the truck trailer has been coupled to the truck.

17. A method comprising:
-
providing an asset tracking unit that is attached to a transportation vehicle; detecting an event in which a door of the transportation vehicle is opened or closed; and refraining from reporting the event unless the event occurred within less than a predetermined period of time after at least one prior event in which the door was opened or closed.

18. An asset tracking system comprising:
-
a server computer; a plurality of asset tracking units, each attached to a respective transportation vehicle; and a central station; the server computer programmed to; receive inputs from at least one user to enter at least one event masking parameter; generate at least one event masking rule based at least in part on the entered at least one event masking parameter; and download the at least one event masking rule to at least one of the asset tracking units; and the at least one of the asset tracking units programmed to; receive and store a downloaded event masking rule; detect an event; and determine, based at least in part on the downloaded at least one event masking rule, whether to report the detected event to the central station; wherein the detected event is at least one of;
coupling one of the transportation vehicles to a truck tractor; and
de-coupling one of the transportation vehicles from a truck tractor. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
