Abstract

There is a system for queue-based processing of RFID locating and sequencing at a site comprising one or more queues that are maintained and updated as locating and sequencing occurs, to ensure that out of sequence, or other complex processing, does not render inaccurate the locating and sequencing.

Claims

1. A method for accurate processing of a locating action event for an asset using queues, wherein a park queue, a parked queue, an unpark queue and a delay queue each may comprise one or more packets of one or more assets that have information about the asset, received from one or more gateways, that are separately processed and stored in a database by a system that can analyze packets to determine and process locating actions, wherein the system potentially processes packets and locating actions out of order based on one or more external factors or internal factors, the method comprising:

receiving a packet relating to the asset;

determining, from the packet, a packet type;

obtaining a result of a locating action, performed on the packet and based on the packet type;

removing the asset from one or more inappropriate queues, if the asset is in one or more inappropriate queues, based on the packet type and the result;

placing the asset in one or more appropriate queues based on the packet type and the result; and

updating the information about the asset in one or more appropriate queues based on the packet.

2. The method of claim 1 wherein the receiving is from an arrival queue that obtains all packets from one or more gateways.

3. The method of claim 2 wherein the receiving further comprises removing duplicate packets from the arrival queue.

4. The method of claim 1 wherein, if the appropriate queue is the parked queue, the placing further comprises confirming that the packet has been processed in the database.

5. The method of claim 1 wherein the receiving is from one of the park queue or the delay queue.

6. The method of claim 1 wherein, if the appropriate queue is the park queue or the delay queue then repeating the obtaining, removing, placing and updating until the appropriate queue is not the park queue or the delay queue.

7. The method of claim 6 wherein the locating action is a parking calculation, the result is a real parking spot, the packet type is a stopped packet or a stationary packet, the inappropriate queues are the delay queue and the unpark queue and the appropriate queue is the park queue.

8. The method of claim 1 wherein the locating action is an unparking action, the packet type is a motion packet, the inappropriate queues are the park queue, delay queue and the parked queue and the appropriate queue is the unpark queue.

9. The method of claim 8 further comprising removing the packet from the unpark queue after confirming that the packet has been removed from the database.

10. A system for accurate processing of a locating action event for an asset using queues, wherein a park queue, a parked queue, an unpark queue and a delay queue each may comprise one or more packets of one or more assets that have information about the asset, received from one or more gateways, that are separately processed and stored in a database by a system that can analyze packets to determine and process locating actions, wherein the system potentially processes packets and locating actions out of order based on one or more external factors or internal factors, the method comprising:

one or more assets configured to transmit packets to one or more gateways;

one of more gateways configured to receive packets from one or more assets and transmit packets to a location management system; and

a location management system further comprising a database, a park queue, a parked queue, an unpark queue and a delay queue that each may comprise one or more packets of one or more assets that have information about the asset, configured to;

analyze, process and store packets in the database to determine and process locating actions;

receive a packet relating to the asset;

determine, from the packet, a packet type;

obtain a result of a locating action, performed on the packet and based on the packet type;

remove the asset from one or more inappropriate queues, if the asset is in one or more inappropriate queues, based on the packet type and the result;

place the asset in one or more appropriate queues based on the packet type and the result; and

update the information about the asset in one or more appropriate queues based on the packet.

11. The system of claim 10 wherein the receiving is from an arrival queue that obtains all packets from the one or more gateways.

12. The system of claim 11 wherein the receiving further comprises removing duplicate packets from the arrival queue.

13. The system of claim 10 wherein, if the appropriate queue is the parked queue, the placing further comprises confirming that the packet has been processed in the database.

14. The system of claim 10 wherein the receiving is from one of the park queue or the delay queue.

15. The system of claim 10 wherein, if the appropriate queue is the park queue or the delay queue then repeating the obtaining, removing, placing and updating until the appropriate queue is not the park queue or the delay queue.

16. The system of claim 15 wherein the locating action is a parking calculation, the result is a real parking spot, the packet type is a stopped packet or a stationary packet, the inappropriate queues are the delay queue and the unpark queue and the appropriate queue is the park queue.

17. The system of claim 10 wherein the locating action is an unparking action, the packet type is a motion packet, the inappropriate queues are the park queue, delay queue and the parked queue and the appropriate queue is the unpark queue.

18. The system of claim 17 wherein the location management system is further configured to remove the packet from the unpark queue after confirming that the packet has been removed from the database.
