Abstract

Embodiments of the present technology may include a method to enable real-time data requests. The method may include subscribing to real-time data enable requests for a device on an energy generation (EG) network. The method may also include intercepting, from a requester, a request for real-time data for the device on an EG system within the EG network. The method may further include publishing a single request to the device to post a single measurement corresponding to the real-time data request. The single request may be published at less than or equal to a predetermined frequency for a request cycle that lasts for a predetermined duration.

First claim

What is claimed is:

1. A method comprising:
subscribing to real-time data enable requests for a device on an energy generation (EG) network;
intercepting, from a first requester, a first request for real-time data for the device on an EG system within the EG network;
intercepting, from a second requester, a second request for real-time data for the device within a predetermined period after intercepting the first request; and
publishing a single request to the device to post a single measurement corresponding to the real-time data request; wherein:
publishing the single request comprises publishing at less than or equal to a predetermined frequency for a predetermined duration, and
the predetermined period is a reciprocal of the predetermined frequency.

2. The method of claim 1 , further comprising:
receiving the single measurement from the device, and
sending the single measurement to the first requester.

3. The method of claim 1 , further comprising:
sending the single measurement to the first requester, and
sending the single measurement to the second requester.

4. The method of claim 1 , wherein the single request is published at the predetermined frequency.

5. The method of claim 1 , wherein the single request to the device is a first single request to the device to post the single measurement, and
further comprising:
determining that the single measurement was not posted in response to the single request, and
publishing a second single request to the device to post the single measurement when the single measurement is not received within a predetermined period after publishing the first single request to the device to post the single measurement, wherein the predetermined period is greater than a reciprocal of the predetermined frequency.

6. The method of claim 5 , wherein the predetermined period is greater than or equal to 20% longer than the reciprocal of the predetermined frequency.

7. The method of claim 5 , wherein the predetermined period is from 10 seconds to 1 minute.

8. The method of claim 1 , wherein the request originates from a web client or a data logger.

9. The method of claim 1 , wherein the predetermined frequency is one request every 100 milliseconds to 30 seconds.

10. The method of claim 1 , wherein the predetermined duration is from 5 to 30 minutes.

11. The method of claim 1 , wherein the intercepting is performed by a real-time enabler operating on a message bus system, and wherein the real-time enabler intercepts all real-time data requests from any requester on the EG network.

12. The method of claim 11 , wherein the EG network comprises a plurality of EG systems.

13. The method of claim 1 , wherein the predetermined frequency is based on the device.

14. The method of claim 1 , wherein the real-time data is comprises energy generation or load data of the device.

15. A computer system comprising:
a non-transitory computer readable medium storing a plurality of instructions that when executed control the computer system to send a single measurement corresponding to a real-time data request to a first requester, the plurality of instructions comprising:
intercepting, from the first requester, a first request for real-time data for the device on an energy generation (EG) system within an EG network;
intercepting, from a second requester, a second request for real-time data for the device within a predetermined period after intercepting the first request; and
publishing a single request to the device to post the single measurement corresponding to the real-time data request; wherein:
publishing the single request comprises publishing at less than or equal to a predetermined frequency for a request cycle that lasts for a predetermined duration, and
the predetermined period is a reciprocal of the predetermined frequency.

16. The method of claim 1 , wherein the predetermined duration is from 1 minute to 5 minutes.

17. The computer system of claim 15 , wherein the predetermined frequency is one request every 100 milliseconds to 1 minute.
