Abstract

Communicating data via an advanced metering infrastructure (AMI). An infrastructure is disclosed that includes: a plurality of communication modules incorporated into a plurality of associated utility meters; a data aggregator configured for communicating with each of the plurality of communication modules, wherein the data aggregator includes a system for translating meter specific data formats into an aggregated format that includes data quality attributes and a timestamp, and includes a system for synchronizing aggregated data over a back haul; and a head end system having a communication management system that receives and processes synchronization messages from the data aggregator received over the back haul, wherein the head end system includes a metering system for requesting and obtaining meter data from the associated utility meters via the data aggregator, and issuing signals to individual meters and groups of meters.

Claims

1. A data aggregator for use in an advanced metering infrastructure (AMI), comprising:

a communication system for communicating with a plurality of communication modules resident in a plurality of associated utility meters;

a data collection system for collecting messages from the plurality of communication modules;

an aggregation system for managing messages as aggregated data in an addressable memory space;

a back haul interface for communicating via a back haul to a head end system; and

a data presentation system for transmitting aggregated data to a head end system via the back haul such that the head end system is synchronously updated with changes in data from the data aggregator.

2. The data aggregator of claim 1, wherein the messages are communicated spontaneously between the plurality of associated utility meters and the head end system.

3. The data aggregator of claim 1, wherein the messages include metrology data and status data.

4. The data aggregator of claim 1, wherein the aggregation system includes:

a system for grouping controllable data points such that commanding a change to a single controllable data point affects a set of utility meters in a defined group;

a system for disseminating grouping information to the plurality of communication modules in the plurality of associated utility meters; and

a system for broadcasting a message addressed to groups of utility meters such that all utility meters receive the message.

5. The data aggregator of claim 1, further comprising an asset management agent, wherein the asset management agent interacts with a remote asset management system to implement new utility meters.

6. The data aggregator of claim 4, wherein the asset management agent interacts with a remote asset management system to implement a grouping function to partition utility meters into groups.

7. A communication card for use with an associated utility meter in an advanced metering infrastructure (AMI), comprising:

a meter interface for communicating with the associated utility meter;

a communication interface for communicating data with a data aggregator; and

a message processing system for managing inbound and outbound messages, including transmitting event data relating to charging a plug-in hybrid electric vehicle (PHEV).

8. The communication card of claim 7, wherein the message processing system further includes processing outbound messages selected from a group consisting of:

accumulation/demand data;

detection of event conditions;

a home area network security event;

detection of meter tampering;

detection of a self-test failure;

event data associated with activation of a local communication; and

home area network node addition/removal.

9. The communication card of claim 7, wherein the message processing system further includes processing inbound messages selected from a group consisting of:

a service connection/disconnection request;

a head end system having a communication management system that receives and processes a synchronization message from the data aggregator received over the back haul, and wherein the head end system includes a metering system for requesting and obtaining meter data from the associated utility meters via the data aggregator.

11. The AMI of claim 10, wherein each communication module includes:

a meter interface for communicating with one of the plurality of associated utility meters; and

a communication interface for exchanging data with the data aggregator.

12. The AMI of claim 11, wherein each communication module further includes:

a spontaneous message processing system for managing a spontaneous message; and

a group manager for selective enforcement of and inbound message addressed to an individual meter or a group of meters.

13. The AMI of claim 12, wherein the spontaneous message includes an outbound message selected from a group consisting of:

accumulation/demand data;

a detection of an event condition;

a home area network security event;
