Abstract

Disclosed are apparatus and methodology subject matters for providing an interface between a meter in an advanced metering system and an application running on such a system. The interface operates effectively as a device driver to translate communication protocols so that plug-n-play functionality (interchangeability) may be provided for meters provided from various venders in an open operational framework, such as for ANSI standard C12.22 meters. The interface provides a plug-in based library that interfaces between the user interface and a data collection engine that is designed to optimize data collection functionality. Optimization is achieved, at least in part, by providing data request processing separately from response processing. Separate response processing allows for the possibility of unsolicited messages being processed for later association with other possible jobs.

Claims

1. A utility meter for use within an advanced metering system operating relative to a network and having other utility meters, user interfaces, and central collection functionality, comprising:

metrology for monitoring the consumption or production of a commodity;

at least one communications module configured to effect bi-directional communications between said utility meter and other networked devices using an open standard meter communication protocol; and

an interface for permitting transmission of information between said metrology and one or more operational applications associated with said utility meter, said interface functioning as a device driver for said utility meter that is capable of interfacing with a user interface and central collection functionality.

2. A utility meter as in claim 1, wherein said interface employs a message manager for the open standard meter communication protocol, said message manager configured to create message objects merged with one or more destination addresses and wrapped in an application layer format.

3. A utility meter as in claim 2, wherein said message manager is further configured to parse received communications by extracting message objects and destination addresses from the received communications.

4. A utility meter as in claim 1, wherein said interface processes exception requests defining whether power outages have occurred at locations within a metering system.

5. A utility meter as in claim 1, wherein said interface comprises a plug-in based library that allows for interchangeable inclusion of said utility meter in an advanced metering system comprising other utility meters and central collection functionality.

6. A utility meter as in claim 1, wherein said interface is configured to separately customize request processing and response processing for central collection functionality, so as to optimize functionality for the central collection functionality from within the user interface.

7. A method of permitting transmission of information between utility meter metrologies and one or more operational applications associated with a utility meter, said method comprising steps of:

providing a network including central collection functionality and a plurality of end devices;

configuring the network for bi-directional communications between the central collection functionality and each of the plurality of end devices using an open standard meter communication protocol; and

providing an interface at each of the plurality of end devices that is capable of interfacing with a user interface and central collection functionality.

8. A method as in claim 7, wherein said interface employs a message manager for the open standard meter communication protocol, said message manager being configured to create message objects merged with one or more destination addresses and wrapped in an application layer format.

9. A method as in claim 8, wherein said message manager is further configured to parse received communications by extracting message objects and destination addresses from the received communications.

10. A method as in claim 7, further comprising a step of processing exception requests defining whether power outages have occurred at locations within a metering system.

11. A method as in claim 7, wherein the interface comprises a plug-in based library that allows for interchangeable inclusion of said utility meter in an advanced metering system comprising other utility meters and central collection functionality.

12. A method as in claim 7, wherein the interface accommodates separate customization for request processing and response processing for central collection functionality, so as to optimize functionality for the central collection functionality from within the user interface.

13. An advanced metering system, comprising:

a plurality of end devices, at least some of which end devices comprise metrology devices;

a network including central collection functionality comprising a collection engine, said network being configured for bi-directional communications between said central collection functionality and each of said plurality of end devices, said bi-directional communications occurring at least in part based on an open standard meter communication protocol; and

an interface at selected end devices for permitting transmission of information between said metrology devices associated with each of said selected end devices and one or more operational applications associated with each of said selected end devices, said interface functioning as a device driver for each of said selected end devices, and configured for interfacing with a user interface and central collection functionality.

14. An advanced metering system as in claim 13, wherein said interface employs a message manager for the open standard meter communication protocol, said message manager configured to create message objects merged with one or more destination addresses and wrapped in an application layer format.

15. An advanced metering system as in claim 14, wherein said message manager is further configured to parse received communications by extracting message objects and destination addresses from the received communications.

16. An advanced metering system as in claim 13, wherein said interface processes exception requests defining whether power outages have occurred at locations within a metering system.

17. An advanced metering system as in claim 13, wherein said interface comprises a plug-in based library that allows for interchangeable insertion of said utility meter in an advanced metering system comprising other utility meters and central collection functionality.

18. An advanced metering system as in claim 13, wherein said interface is configured to separately customize request processing and response processing for the central collection functionality, so as to optimize functionality for the central collection functionality from within the user interface.
