Abstract

A system is described for determining a relative location of a plurality of items upon a plurality of platforms. The system may include a memory, an interface, and a processor. The memory may store a first item, a second item, a first period of time and a second period of time. The interface may be operative to communicate with a user and an antenna. The antenna may be able to detect an item for a period of time. The processor may be operative to receive from the antenna, via the interface, the first item, the first period of time, the second item and the second period of time. The processor may determine whether the periods of time overlap. If the periods of time overlap the processor may communicate to the user that the items are upon the same platform, otherwise that the items are on consecutive platforms.

Claims

1. A method for determining a relative location of a plurality of tagged slabs, the method comprising:

tagging a plurality of slabs with a plurality of radio frequency identification tags, wherein each slab of the plurality of slabs is tagged with a respective radio frequency identification tag of the plurality of radio frequency identification tags;

loading the plurality of slabs onto a plurality of wagons;

moving the plurality of slabs past a reader;

detecting, with the reader, a first radio frequency identification tag on a first slab of the plurality of slabs for a first period of time and a second radio frequency identification tag on a second slab of the plurality of slabs for a second period of time;

performing an analysis on the first period of time and the second period of time to determine whether the first slab and the second slab were loaded onto the same wagon or onto consecutive wagons; and

storing in a data store a data describing that the first slab and the second slab were loaded onto the same wagon when the analysis determines the first slab and the second slab were loaded onto the same wagon, otherwise storing in the data store a data describing that the first slab and the second slab were loaded onto consecutive wagons.

2. The method of claim 1 wherein the analysis on the first period of time and the second period of time to determine when the first slab and the second slab are upon one wagon or are upon consecutive wagons further comprises:

identifying a time interval threshold, wherein the time interval threshold indicates a maximum allowable time interval between slabs on the same wagon;

calculating a time interval between a start of the first time period and a start of the second time period; and

determining that the first slab and the second slab are on the same wagon when the time interval is less than the time interval threshold, otherwise determining that the first slab and the second slab are on consecutive wagons.

3. The method of claim 1 wherein performing an analysis on the first period of time and the second period of time to determine when the first slab and the second slab are upon one wagon or are upon consecutive wagons further comprises determining that the first slab and the second slab are on the same wagon when the first time period overlaps the second time period, otherwise determining that the first slab and the second slab are on consecutive wagons.

4. The method of claim 1 wherein the plurality of wagons comprises a plurality of train wagons.

5. The method of claim 1 wherein the plurality of slabs comprises a plurality of steel slabs.

6. The method of claim 1 wherein at least one of the antenna, the plurality of slabs and the plurality of wagons is fixed and at least one of the antenna, the plurality of slabs and the plurality of wagons is moving.

7. The method of claim 1 wherein each tag includes a data describing the slab.
