Abstract

A system for monitoring a plurality radio frequency identification tags is described. The system uses at least one set of radio frequency identification tags. Each tag is attached to a container and includes several sensors for detecting physical conditions of said container. The system includes at least one autonomous intermediate reader in wireless communication with the frequency identification tags. The intermediate reader includes external wireless communication system, intermediate reader logic controller, and a self-contained rechargeable power supply. The system uses a central status reporting system in communication the intermediate reader.

First claim

The embodiment of the invention in which an exclusive property or privilege is claimed is defined as follows:

1. A system for monitoring a plurality radio frequency identification tags comprising:
at least one set of radio frequency identification tags wherein each tag comprises a tag body wherein said tag body contains a means to attach said tag body to at least one container, a plurality of sensors for detecting physical conditions of said container, a power supply in communication with said body, tag radio communication means, tag control logic, tag storage memory containing status of said plurality of sensors; wherein power supply comprises a long life battery bank wherein each battery within the bank is used independently;
at least one self-contained autonomous intermediate reader in wireless communication with said at least one set of radio frequency identification tags wherein said intermediate reader comprises tag radio communication means, external wireless communication means, intermediate reader logic controller, a self-contained rechargeable power supply; wherein said self-contained autonomous intermediate reader is not coupled to a vehicle used to convey the self-contained autonomous intermediate reader and tags; and
at least one central status reporting system comprising a data store, a user interface, wireless communication link, and control logic, wherein said wireless communication link is in communication with said at least one autonomous intermediate reader;
wherein said set of radio frequency tags establishes a local network with said intermediate reader which in turn communicates with said central status reporting system transmitting data from the at least one intermediate reader to the central status reporting system data store using the central status reporting system wireless communication link, said data store is in turn is processed by the central reporting system control logic.

2. The system of claim 1 wherein said each tag sensor comprises sensors for shock, temperature, surface gamma radiation load, surface neutron emission load, container structural integrity, container security.

3. The system of claim 1 wherein intermediate reader logic controller and tag control logic is programmed to allow the intermediate reader to alter the tag storage memory.

4. The system of claim 1 wherein each tag comprising the set of radio frequency tags is not in direct communication with the intermediate reader and wherein each tag is addressable by the intermediate reader via messages relayed from other tags in communication with the intermediate reader.

5. The system of claim 1 wherein said intermediate reader sends and receives commands from said central status reporting system without additional intervention.

6. The system of claim 1 wherein said intermediate reader is mobile.

7. The system of claim 1 wherein said intermediate reader is removably installed in proximity to the set of radio frequency identification tags.

8. The system of claim 1 wherein said intermediate reader is only accessible via said central status reporting system.

9. The system of claim 1 wherein said intermediate reader polls the status of said set of radio frequency tags at regular intervals and forwards said status to said central status reporting system at irregular intervals.

10. The system of claim 1 wherein said self-contained rechargeable power supply is selected to provide sufficient power for the duration of transit of said set of radio frequency identification tags.

11. The system of claim 1 wherein said intermediate reader comprises no external wires.

12. The system of claim 1 wherein said means to attach said tag body to the container comprises an insulated conducting wire loop.

13. The system of claim 1 wherein said autonomous intermediate reader further comprises a DC to DC converter.

14. The system of claim 1 wherein said external wireless communication means comprises an intermittent communications channel to the central status reporting system and wherein said autonomous intermediate reader caches data for transmission during periods of availability of communications with the central status reporting system.

15. The system of claim 1 wherein said central status reporting system comprises a data store.

16. The system of claim 1 wherein said autonomous intermediate reader comprises a watchdog process.

17. The system of claim 12 wherein said tag body detects a loss of integrity within the wire loop.

18. A system for monitoring a plurality radio frequency identification tags comprising:
at least one set of radio frequency identification tags wherein each tag comprises a tag body wherein said tag body contains a means to attach said tag body to at least one container, a plurality of sensors for detecting physical conditions of said container, a power supply in communication with said body, tag radio communication means, tag control logic, tag storage memory containing status of said plurality of sensors; a discharge circuit in communication with the power supply; and a set of non-rechargeable batteries integrated into the discharge circuit; wherein
the power supply comprises a long life battery bank wherein each battery within the bank is used independently;
at least one self-contained autonomous intermediate reader in wireless communication with said at least one set of radio frequency identification tags wherein said intermediate reader comprises tag radio communication means, external wireless communication means, intermediate reader logic controller, a self-contained rechargeable power supply; wherein said self-contained autonomous intermediate reader is not coupled to a vehicle used to convey the self-contained autonomous intermediate reader and tags and
at least one central status reporting system in communication with said intermediate reader wherein said central status reporting system comprises a multi-purpose computer having a data store and a link to an external network wherein said intermediate reader communicates with said central status reporting system using said external network;
wherein said set of radio frequency tags establishes a local network with said intermediate reader which in turn communicates with said central status reporting system using the external wireless communications means.

19. A system for monitoring a plurality radio frequency identification tags comprising:
at least one set of radio frequency identification tags wherein each tag comprises a tag body wherein said tag body contains a means to attach said tag body to at least one container, a plurality of sensors for detecting physical conditions of said container, a power supply in communication with said body, tag radio communication means, tag control logic, tag storage memory containing status of said plurality of sensors; wherein
the power supply comprises a long life battery bank wherein each battery within the bank is used independently;
at least one self-contained autonomous intermediate reader in wireless communication with said at least one set of radio frequency identification tags wherein said intermediate reader comprises tag radio communication means, external wireless communication means, intermediate reader logic controller, a self-contained rechargeable power supply; wherein said self-contained autonomous intermediate reader is not coupled to a vehicle used to convey the self-contained autonomous intermediate reader and tags; and
at least one reporting system in communication with said intermediate reader; wherein said repor
