Abstract:
1. A method of tracking inventory transferred within a freight yard, comprising the steps of: creating a plurality of digital records, wherein each record includes position data representing a physical position of a vehicle; updating a first position data of a first record corresponding to a first vehicle, within the freight yard, wherein the first vehicle is carrying inventory, and wherein the first position data is updated with position data transmitted by and received from a first navigation system attached to the first vehicle; unsecuring the inventory from the first vehicle whereby a signal that an unlatch event has occurred is sent by the first navigation system; securing the inventory to a second vehicle within the freight yard, said second vehicle having a second navigation system attached thereto, whereby a latch event signal is sent from the second navigation system; detecting the latch and unlatch event signals sent from the, respective, first and second navigation systems and determining the proximity of the first vehicle that sent the unlatch event signal relative to the second vehicle that sent the latch event signal; comparing the first position data of the first record with the position data of the plurality of digital records to determine if the second vehicle is a closest vehicle that had a latch event, and if the second vehicle associated with the sent latch event signal is determined to be the closest vehicle to the first vehicle associated with the unlatch event signal, the inventory carried by the first vehicle is determined to be transferred from the first vehicle to the second vehicle; updating the first record to reflect that the first vehicle is no longer carrying the inventory; and updating a record of the second vehicle to reflect that the second vehicle is now carrying the inventory.
