Abstract

Methods of operating a communication node are provided. A method of operating a communication node may include receiving data from an electric grid device via a network interface. The method may include processing the data from the electric grid device at the communication node. Moreover, the method may include transmitting a filtered portion of the data to an electric utility head end system, after processing the data at the communication node. In some embodiments, a method of operating a communication node may include using a message broker controlled by a virtual machine in the communication node to provide a protocol to interface with a field message bus that includes a standards-based or open-source Application Programming Interface (API). Related communication nodes and computer program products are also described.

First claim

What is claimed is:

1. A method of operating a first device corresponding to a gas, water, or electric grid, the method comprising:
receiving data, via a network interface, from a second device corresponding to the gas, water, or electric grid;
processing the data from the second device at the first device; and
transmitting a filtered portion of the data to a data center comprising an utility head end system corresponding to the gas, water, or electric grid, after processing the data at the first device,
wherein processing the data comprises determining a response decision at the first device, with respect to the data received from the second device, before transmitting the filtered portion of the data to the data center,
wherein the response decision comprises a response to an event at the second device or at a third device corresponding to the gas, water, or electric grid, and
wherein the response to the event comprises a response to a power outage or to a change in electricity production.

2. The method of claim 1 , wherein the network interface comprises a local area network interface or a wide area network interface.

3. The method of claim 1 , wherein the filtered portion of the data received from the second device comprises at least one electric grid parameter, water grid parameter, gas grid parameter, networking parameter, customer parameter, security parameter, device identification parameter, or time-stamp parameter.

4. The method of claim 1 , further comprising transmitting the response decision to the utility head end system.

5. The method of claim 4 , further comprising transmitting the response decision to the third device corresponding to the gas, water, or electric grid.

6. The method of claim 5 , wherein:
the first, second, and third devices comprise first, second, and third electric grid devices, respectively, corresponding to the electric grid; and
transmitting the response decision comprises transmitting the response decision from the first electric grid device to the utility head end system and to the third electric grid device.

7. The method of claim 5 , wherein:
the first and second devices comprise first and second electric grid devices, respectively, corresponding to the electric grid;
the third device comprises a communication node corresponding to a third electric grid device that corresponds to the electric grid;
transmitting the response decision comprises transmitting the response decision from the first electric grid device to the utility head end system and to the communication node corresponding to the third electric grid device.

8. The method of claim 5 , wherein:
the first device comprises a communication node corresponding to a first electric grid device that corresponds to the electric grid;
the second and third devices comprise second and third electric grid devices, respectively, corresponding to the electric grid; and
transmitting the response decision comprises transmitting the response decision from the communication node corresponding to the first electric grid device to the utility head end system and to the third electric grid device.

9. The method of claim 1 , wherein processing the data comprises reading Application Layer data at the first device.

10. The method of claim 1 , wherein:
the utility head end system is configured to provide communications via a data center message bus; and
the method further comprises transmitting, in response to processing the data from the second device at the first device, the filtered portion of the data to the third device corresponding to the gas, water, or electric grid, via a field message bus that is configured to provide communications independently of the data center message bus.

11. The method of claim 1 , wherein the first and second devices correspond to different first and second vendors, respectively.

12. The method of claim 1 , wherein the first device comprises an electric grid device, a water grid device, a gas grid device, a telecommunications system device, a server, or a home appliance.

13. A computer program product comprising a non-transitory computer readable storage medium including computer readable program code therein configured to perform the method of claim 1 .

14. A method of operating a first device corresponding to a gas, water, or electric grid, the method comprising:
receiving data, via a network interface, from a second device corresponding to the gas, water, or electric grid;
processing the data from the second device at the first device;
transmitting a filtered portion of the data to a data center comprising an utility head end system corresponding to the gas, water, or electric grid, after processing the data from the second device at the first device; and
transmitting the filtered portion of the data to a third device corresponding to the gas, water, or electric grid, via a field message bus, after processing the data from the second device at the first device,
wherein the first, second, and third devices are spaced apart from the data center, and
wherein transmitting the filtered portion of the data to the third device comprises transmitting the filtered portion of the data via peer-to-peer communication between the first and third devices.

15. The method of claim 14 ,
wherein processing the data comprises determining a response decision at the first device, with respect to the data received from the second device, before transmitting the filtered portion of the data to the data center, and
wherein transmitting the filtered portion of the data to the third device comprises transmitting the response decision to a utility grid asset that is configured to implement the response decision and that is spaced apart from the data center.

16. The method of claim 15 , wherein the response decision is implementable by:
the second device;
the third device; and/or
a fourth device corresponding to the gas, water, or electric grid and spaced apart from the data center.

17. A method of operating a first device corresponding to a gas, water, or electric grid, the method comprising:
receiving data, via a network interface, from a second device corresponding to the gas, water, or electric grid;
processing the data from the second device at the first device;
transmitting a filtered portion of the data to a data center comprising an utility head end system corresponding to the gas, water, or electric grid, after processing the data from the second device at the first device; and
transmitting the filtered portion of the data to a third device corresponding to the gas, water, or electric grid, via a field message bus, after processing the data from the second device at the first device,
wherein the first, second, and third devices are spaced apart from the data center, and
wherein receiving data from the second device comprises obtaining voltage and/or current data every second.
