Abstract
A gateway node detects loading of a unit load device (ULD) into a vehicle by fusing sensed information. The gateway node, physically coupled to a loading platform of a loader, determines its location and a vehicle identifier (ID) of the vehicle based on the location. The gateway node detects an increase in elevation of the loading platform and receives a movement message containing a unique ID of a tape node attached to the ULD. The gateway node determines that the ULD is being loaded into the vehicle based on the vehicle ID, the detected increase in elevation of the loading platform, and an association of the unique ID with the ULD.
