Abstract

A distributed metering platform virtualizes functions of a conventional metrology sensor and separates the virtualized functions from a metrology sensor. One or more virtual meters or applications may be instantiated at a network communication device that is remote from the metrology sensor and processes metrology data received from the metrology sensor. Each virtual meter may include multiple partitioned application spaces that are isolated from one another. In one example, a first application space includes a locked version of code and a second application space includes an unlocked version of code. Furthermore, each virtual meter may be isolated from other virtual meters such that each virtual meter is unable to affect operations and/or data associated with other virtual meters.

3. The network communication device as recited in claim 2, wherein the first virtual meter and the second virtual meter separately receive the digitalized metrology data from the first remote metrology sensor and the second remote metrology sensor over a communication network, the communication network comprising a wireless network and/or a wired network.

4. The network communication device as recited in claim 2, wherein the communication interface sends a control signal to the first remote metrology sensor or the second remote metrology sensor to remotely disconnect a utility service from serving the respective first or second point of service.

5. The network communication device as recited in claim 4, wherein the utility service comprises water, electricity or gas.

6. The network communication device as recited in claim 2, further comprising a networking module to transmit the digitalized metrology data received from the first remote metrology sensor and the second remote metrology sensor to a utility provider.

7. The network communication device as recited in claim 1, further comprising an operating system, wherein the first virtual meter and the second virtual meter are run using the operating system.

8. The network communication device as recited in claim 1, further comprising:

a common data store accessible by the first virtual meter and the second virtual meter.

9. The network communication device as recited in claim 1, wherein each of the at least one of the plurality of applications that has code that is locked is a locked application, wherein each of the at least one of the plurality of applications that has code that is unlocked is an unlocked application, and wherein each of the first and second virtual meters is configured to:

execute the locked application and the unlocked application;

compare output of the locked application and the unlocked application;

lock the unlocked application to create a newly locked application if results of the unlocked application are within a threshold of results of the locked application; and

replace the locked application with the newly locked application, wherein functions performed by the locked application are thereafter performed by the newly locked application.

10. The network communication device as recited in claim 9, wherein:

execution of the locked application and the unlocked application comprises execution of a locked metering application and an unlocked metering application; and

replacement of the locked application with the newly locked application comprises updating a configuration file to indicate the newly locked application.

11. A system comprising:

a first metering element to collect utility consumption data from a first point of service;

a second metering element to collect utility consumption data from a second point of service; and

first and second virtual meters within a network communication device that is remote from each of the first and second metering elements, each of the first and second virtual meters comprising;

a dedicated memory space in each of the first virtual meter and the second virtual meter that is unavailable to the other of the second virtual meter and the first virtual meter, respectively, wherein digitized metrology data is received by each of the first virtual meter and the second virtual meter through a communications network, wherein the digitized metrology data is associated with the first point of service and the second point of service, and wherein the first point of service and the second point of service are associated with the first virtual meter and the second virtual meter, respectively; and
