Abstract

Disclosed are apparatus and methodology for providing remote system upgrades to utility meters in certain regulatory environments. A utility meter having a metrology section and a registry portion is provided with additional memory in the metrology section, and configured as the primary storage location for billing information. The metrology section is configured for remote upgrade of firmware associated with automatic meter reading (AMR) functions in a manner that maintains the integrity of stored billing material despite any failed upgrade of the associated AMR device or functionality

Claims

1. Methodology for providing remote system upgrades to electricity meters in regulated residential single phase environments, for making in-service modifications to such meters while maintaining the integrity of billing data stored therein, comprising:

providing a plurality of electricity meters, each having automatic meter reading (AMR) functionality and each directly or indirectly associated with a communications link for respectively forwarding billing data to a billing center for processing of such billing data;

providing each of the electricity meters with respective metrology sections and separate register sections, each such metrology section having primary billing data memory configured to serve as the primary storage location for billing data determined by the associated electricity meter, each such register section having transferred billing data memory configured to receive billing data transferred thereto from its respectively associated metrology section memory, and each such electricity meter being configured for remote upgrade of automatic meter reading (AMR) functionality thereof while maintaining the integrity of stored billing data therein, despite any failed upgrade attempt;

conducting an in-service modification to one or more targeted meters of such plurality of electricity meters; and

subsequent to an upgrade or an attempted upgrade of such targeted meters, respectively forwarding billing data from the metrology sections of such targeted meters to the respective register sections thereof, for reporting to the billing center without loss of billing data integrity during any in-service modifications or attempted modifications to such targeted meters.

2. Methodology as in claim 1, wherein:

the in-service modification comprises an in-service firmware update of the Register/AMR system of such meter; and

the register section transferred billing data memory includes one of a memory location in such section or a visual display associated with the electricity meter.

3. Methodology as in claim 1, wherein:

the register section transferred billing data memory includes a memory location in such section; and

the method further includes using one of a handheld device, a laptop, or PC to make the billing data content of such memory location available to the meter owner.

4. Methodology as in claim 1, further including performing periodic checks to ensure that meter billing data and data retrieved via the AMR functionality are in synch.

5. Methodology as in claim 1, further including:

determining that an in-service modification has failed for a targeted meter; and

using billing data recovered from the metrology section of such determined meter for forwarding to the register section thereof.

6. Methodology for providing remote system upgrades to utility meters in regulated residential environments, for making in-service modifications to such meters while maintaining the integrity of billing data stored therein, comprising:

providing a plurality of utility meters, each having automatic meter reading (AMR) functionality for respectively forwarding billing data to a billing center; and

providing each of the utility meters with respective metrology sections and separate register sections, each such metrology section having additional memory configured to serve as the primary storage location for billing data determined by the associated utility meter;

wherein each such meter is configured for remote upgrade of automatic meter reading (AMR) functionality thereof while maintaining the integrity of stored billing data in the metrology section additional memory thereof, despite any failed upgrade attempt.

7. Methodology as in claim 6, further including:

conducting an in-service modification to one or more targeted meters of such plurality of utility meters; and

subsequent to an upgrade or an attempted upgrade of such targeted meters, respectively forwarding billing data from the metrology sections of such targeted meters to the respective register sections thereof, for reporting to the billing center without loss of billing data integrity during any in-service modifications or attempted modifications to such targeted meters.

8. Methodology as in claim 6, wherein:

the register section includes one of a memory location in such section or a visual display associated with the utility meter;

the in-service modification comprises an in-service firmware update of the Register/AMR system of such meter; and

such methodology further includes replacing as necessary a register section of an electricity meter in an on-site operation without requiring recertification of the separate metrology section of such electricity meter, and without loss of billing data therefrom.

9. Methodology as in claim 6, wherein:

the register section includes a memory location in such section; and

the method further includes using one of a handheld device, a laptop, or PC to make the billing data content of such memory location available to the meter owner.

10. Methodology as in claim 6, further including:

performing periodic checks to ensure that meter billing data and data retrieved via the AMR functionality are in synch; and

determining that an in-service modification has failed for a targeted meter, and using billing data recovered from the metrology section of such determined meter for forwarding to the register section thereof.

11. An electricity meter adapted for use in regulated residential single phase environments, for enabling in-service modifications to such meter while maintaining the integrity of billing data stored therein, comprising:

an electricity meter having automatic meter reading (AMR) functionality, and configured for one of direct or indirect association with a communications link for respectively forwarding billing data from such meter to a billing center for processing of such billing data; and

a respective metrology section and separate register section in said electricity meter, said metrology section having primary billing data memory configured to serve as the primary storage location for billing data determined by said electricity meter, and said register section having transferred billing data memory configured to receive billing data transferred thereto from said meter metrology section memory;

wherein said electricity meter is further configured for remote upgrade of automatic meter reading (AMR) functionality thereof while maintaining the integrity of stored billing data therein, despite any failed upgrade attempt.

12. An electricity meter as in claim 11, wherein said electricity meter is configured for remote in-service modification comprising an in-service firmware update of the Register/AMR system of such meter.

13. An electricity meter as in claim 11, wherein:

said register section transferred billing data memory comprises one of a memory location in such section or a visual display associated with said electricity meter; and

said register section of said electricity meter is configured to be replaced in an on-site operation without requiring recertification of the separate metrology section of said electricity meter, and without loss of billing data therefrom.

14. An electricity meter as in claim 11, wherein said electricity meter is configured for performing periodic checks as part of ensuring that meter billing data and data retrieved via the AMR functionality are in synch.

15. An electricity meter as in claim 11, wherein said electricity meter is configured for determining that an in-service modification has failed, and for using billing data recovered from said metrology section thereof for forwarding to said register section thereof, and for subsequently forwarding such transferred billing data from said register section to an associated billing center.
