Abstract

An apparatus for providing automatic metering capabilities to a resource grid is provided. The apparatus includes a plurality of existing automatic meter reading (AMR) meters and a plurality of interface devices. Each of the plurality of existing automatic meter reading (AMR) meters is coupled to a resource consumption point, the each is configured to periodically broadcast respective meter readings. Each of the plurality of interface devices is coupled to a corresponding one of the plurality of existing AMR meters, and each of the plurality of interface devices is configured to receive one or more of the respective meter readings, and is configured to provide the one or more of the respective meter readings over an existing communications infrastructure.

Claims

1. An apparatus for providing automatic metering capabilities to a resource grid, the apparatus comprising:

a plurality of existing automatic meter reading (AMR) meters, each coupled to a resource consumption point, said each configured to periodically broadcast respective meter readings; and

a plurality of interface devices, each of said plurality of interface devices coupled to a corresponding one of said plurality of existing AMR meters, said each of said plurality of interface devices configured to receive one or more of said respective meter readings, and configured to provide said one or more of said respective meter readings over an existing communications infrastructure.

2. The apparatus as recited in claim 1, wherein said each of said plurality of interface devices comprises a meter collar that attaches to a standard meter.

3. The apparatus as recited in claim 1, wherein said each of said plurality of interface devices comprises a circuit card assembly that is inserted into a card slot in a standard meter.

4. The apparatus as recited in claim 1, wherein one of said plurality of interface devices is coupled to a high speed device to provide for two-way communication over said existing communications infrastructure.

5. The apparatus as recited in claim 4, wherein remaining ones of said plurality of interface devices are coupled together and are coupled to said one of said plurality of interface devices via a wired star network having legs comprising drops of said existing communications infrastructure.

6. The apparatus as recited in claim 5, wherein said high speed device comprises a digital subscriber line (DSL) modem, and wherein said one of said plurality of interface devices communicates with said remaining ones of said plurality of interface devices via adaptive variable rate serial data transfers over said wired star network.

7. The apparatus as recited in claim 4, wherein all of said plurality of interface devices are coupled together via a wireless mesh network.

8. The apparatus as recited in claim 1, wherein the resource grid comprises an electrical power distribution grid, and wherein said existing communications infrastructure comprises the public switched telephone network, and wherein said respective meter readings are provided via one or more digital subscriber line (DSL) links between the resource grid and a network operations center.

16. The apparatus as recited in claim 1, wherein the metering grid comprises an electrical power distribution grid, and wherein said existing communications infrastructure comprises the public switched telephone network, and wherein first meter readings are provided via one or more digital subscriber line (DSL) links between the metering grid and a network operations center.

9. A metering grid, comprising:

an automatic metering infrastructure (AMI) meter, configured to provide for two-way communications to monitor consumption of a resource and to control consumption of said resource, said AMI meter comprising;

a first automatic meter reading (AMR) meter, configured to periodically broadcast first meter readings corresponding to consumption of said resource; and

a first interface device, configured to receive said first meter readings, and configured to provide said first meter readings over an existing communications infrastructure.

10. The apparatus as recited in claim 9, wherein said first interface device comprises a meter collar that attaches to said AMR meter.

11. The apparatus as recited in claim 9, wherein said first interface device comprises a circuit card assembly that is inserted into a card slot in said AMR meter.

12. The apparatus as recited in claim 9, wherein said first interface device is coupled to a high speed device to provide for two-way communication over said existing communications infrastructure.

13. The apparatus as recited in claim 12, wherein said first interface device is coupled together to a plurality of second interface devices via a wired star network having legs comprising drops of said existing communications infrastructure.

14. The apparatus as recited in claim 13, wherein said high speed device comprises a digital subscriber line (DSL) modem, and wherein said first interface device communicates with said plurality of second interface devices via adaptive variable rate serial data transfers over said wired star network.

15. The apparatus as recited in claim 12, wherein said first and said plurality of interface devices are coupled together via a wireless mesh network.

17. A method for providing automatic metering capabilities to a resource grid, the method comprising:

first coupling each of a plurality of existing automatic meter reading (AMR) meters to a respective resource consumption point;

second coupling each of a plurality of interface devices to the each of a plurality of AMR meters, wherein the each of the interface devices receives meter readings that are broadcast by one or more of the plurality of AMR meters; and

transmitting the meter readings over an existing communications infrastructure to a resource provider.

18. The method as recited in claim 17, further comprising:

third coupling one of the plurality of interface devices to a high speed device to provide for two-way communication over the existing communications infrastructure.

19. The method as recited in claim 18, further comprising:

fourth coupling remaining ones of the plurality of interface devices together and to the one of the plurality of interface devices via a wired star network having legs comprising drops of the existing communications infrastructure.

20. The method as recited in claim 19, wherein the high speed device comprises a digital subscriber line (DSL) modem, and wherein the one of said plurality of interface devices communicates with the remaining ones of the plurality of interface devices via adaptive variable rate serial data transfers over the wired star network.

21. The method as recited in claim 18, wherein all of the plurality of interface devices are coupled together via a wireless mesh network.

22. The method as recited in claim 17, wherein the resource grid comprises an electrical power distribution grid, and wherein the existing communications infrastructure comprises the public switched telephone network, and wherein the meter readings are provided via one or more digital subscriber line (DSL) links between the resource grid and the resource provider.
