Abstract

Systems and methods for improving the performance of data collection networks. Such systems are provided for conditioning and aggregating data from data collection elements and provided for presenting this aggregated data through a common interface. Also included are means for data collection and retention in successive hierarchical proxy levels, providing device aggregation.

Claims

1. A method for managing a plurality of objects using RFID tags in a real-time environment, the method comprising:

transferring information in a first format from one or more RFID tags using an RFID network, the one or more RFID tags being coupled to respective objects, each of the objects being capable of movement by a human user;

capturing information in the first format using one or more RFID readers provided at one or more predetermined spatial region using the RFID network;

parsing the information in the first format into a second format;

processing the information in the second format using one or more processing rules to identify if the one or more RFID tags at a time period of T1 is associated with the one or more RFID tags at a time period of T2;

transferring a portion of the information from the RFID network to an enterprise network;

receiving the portion of the information at an enterprise resource planning process using the enterprise network;

determining if the one or more respective objects is physically present at a determined spatial location or not present at the determined spatial location at the time period T2.

2. The method of claim 1 wherein the one or more respective objects is associated with retail merchandise.

3. The method of claim 1 wherein the predetermined spatial region is mobile or fixed.

4. The method of claim 1 wherein the predetermined spatial region is a portion of a building or other physical entity.

5. The method of claim 1 wherein each of the objects is capable of movement by a robotic entity.

6. The method of claim 1 wherein the human user is assisted with a robotic entity.

7. The method of claim 1 wherein the RFID network comprising a wireless portion.

8. The method of claim 1 wherein the RFID network comprising a wireless portion and a wired portion.

9. The method of claim 1 wherein the first format comprises a header and a payload.

10. The method of claim 1 wherein the transferring from the one or more RFID tags comprising a broadcasting process.

11. A method for processing RFID traffic between a first network and a second network, the method comprising:

transferring information associated with a plurality of RFID tags corresponding to respective plurality of objects in a first format through an RFID network;

processing the information in the first format using one or more rules to identify one or more attributes in a portion of the information in the first format, the one or more attributes in the portion of the information being associated with at least one of the plurality of RFID tags;

processing the portion of the information in the first format associated with the change into information in a second format to be transferred from the RFID network;

transferring the portion of the information in the second format through an enterprise network; and

dropping other information in the first format from being transferred through the enterprise network.

12. The method of claim 11 wherein the portion of the information in the first format is on the order of about at least 1/500th of the portion of the information in the first format.

13. The method of claim 11 wherein the processing of the information and the processing of the portion of the information is provided using a gateway process.

14. The method of claim 11 wherein the RFID network is characterized by a data load of about 100 times a data load of the enterprise network.

15. The method of claim 11 wherein the enterprise network comprises a legacy network.

16. The method of claim 11 wherein the dropping of the other information ceases transfer of the information in the first format from being transferred to the enterprise network.

17. The method of claim 11 wherein the dropping of the other information ceases transfer of the information in the first format from being transferred to the enterprise network, whereupon the dropping reduces a quantity of information to the enterprise network from a first level to a second level in order to reduce a level of congestion of traffic through the enterprise network.

18. A system for managing RFID devices operably disposed in a pre-selected geographic region, the system comprising:

at least 3 RFID readers, each of the RFID readers being spatially disposed in selected determined regions of a physical space;

an RFID network coupled to each of the RFID readers;

an RFID gateway coupled to the RFID network, the RFID gateway being adapted to process information in at least a link layer and a network layer of the RFID network from the at least 3 RFID readers;

an enterprise network coupled to the RFID gateway; and

an ERP management process coupled to the enterprise network and coupled to the RFID gateway.

19. The system of claim 18 wherein the RFID gateway is also adapted to process information in at least a transport layer of the RFID network from the at least 3 RFID readers.

20. The system of claim 18 wherein the RFID network comprises a wired portion and a wireless portion.

21. The system of claim 18 wherein the RFID gateway comprises a conditioning process.

22. The system of claim 18 wherein the RFID gateway is adapted to aggregate information from the RFID readers.

23. The system of claim 18 wherein the RFID gateway is adapted to be a proxy of the plurality of rf reading devices for the ERP management process.

24. The system of claim 18 wherein the RFID gateway is adapted to be a data proxy for information from the plurality of RFID readers for the enterprise network.

25. The system of claim 18 wherein the RFID gateway is characterized as a demarcation point between one or more independent downstream elements and an aggregated upstream view of the one or more independent downstream elements.

26. The system of claim 25 wherein the one or more downstream elements comprising an encapsulation for a unified view.

27. The system of claim 18 wherein the RFID gateway is representative of a single point of access to all the rf reading devices.

28. The system of claim 27 wherein the RFID gateway comprises a common interface.

29. The system of claim 18 wherein the RFID gateway is representative of an aggregated view of any and all information derived from the plurality of rf reading devices.

30. The system of claim 18 wherein the RFID gateway is provided with a low latency access to the plurality of rf reading devices.

31. The system of claim 18 wherein the RFID gateway is provided to cause a reduction to a portion of downstream network traffic due to one or more requests from an upstream network traffic.

32. The system of claim 18 wherein RFID gateway is provided to retain information associated with a relevant state for each of the rf reading devices.
