Abstract

Automatic discovery of configuration or identification information published by a local computer (publisher) connected to electrical monitoring devices in a power monitoring system and to a server that determines whether to approve data packets sent by the publisher. The publisher attempts to send a data packet including identification information to the server, which throws an exception with error code(s) indicating which information is missing in order for the server to approve the pending data transfer. The publisher interprets the error code(s) and sends back to the server the missing information, which may be identification information, configuration information, or both. This process of the server throwing an exception and the publisher attempting to send data packets or configuration information again may iterate more than once until the server approves the publisher, the device, and all topic information associated with the device and accepts the data for storage in the server database.

Claims

1. A method of auto-discovering information associated with devices arranged in a monitoring system that monitors measurable quantities of a utility, comprising:

receiving configuration information from a local computer in the monitoring system at a server, the local computer attempting to send a data packet associated with a device to the server, the device measuring a characteristic of the utility and storing data indicative of the measured characteristic, the data packet including the data and identification information, the configuration information including at least information indicative of a type of the device and topic information indicative of a type of the data in the data packet, the identification information including a unique device identification (ID) associated with the device, a publisher ID indicating an identity of which local computer is attempting to send the data packet, and an originator ID indicating an identity of an installation in which the device is installed;

determining from the configuration information whether the local computer is approved to have the data packet accepted by the server, the determining including comparing the configuration information against system configuration stored in the server;

responsive to the comparing, throwing from the server to the local computer an exception that includes an error code indicating that the configuration information or the identification information in the data packet includes information not recognized by the server;

responsive to the determining, if the local computer is approved, determining whether the device is approved to have the data packet accepted by the server;

responsive to the determining, if the local computer is not approved because the configuration information is not recognized by the server, automatically approving the local computer by updating the system configuration with the configuration information;

responsive to the determining, if the local computer is not approved because the identification information in the data packet is not recognized by the server, learning the identification information by storing the identification information in the server such that subsequent data packets associated with the device sent from the local computer to the server will be recognized as having been sent from the device; and

responsive to the determining, if the local computer is approved and the device is approved to have the data packet accepted by the server, storing in the server the data packet.

2. The method of claim 1, wherein the exception is selected from among a plurality of exception types, each exception type indicating that information which is required by the server to approve the device.

3. The method of claim 2, wherein the configuration information includes local computer information, device information, and topic information.

4. The method of claim 3, wherein a first exception type indicates that the topic information is not approved by the server.

5. The method of claim 4, wherein the topic information is a topic that relates to an electrical characteristic.

6. The method of claim 3, wherein a first exception type indicates that the local computer information is not approved by the server.

7. The method of claim 3, wherein a first exception type indicates that the device information is not approved by the server.

8. The method of claim 1, wherein the utility is selected from the group consisting of water, air, gas, energy, steam, and weather.

9. The method of claim 8, wherein the monitoring system is a power monitoring system and the utility is energy.

10. The method of claim 9, wherein the data packet includes electrical data.

11. The method of claim 1, wherein the data packet includes identification information, the method further comprising:

determining from the identification information whether the device is approved to have the data packet accepted by the server;

if the device is approved, accepting the data packet at the server and storing the data packet in a database of the server; and

if the device is not approved, throwing an exception from the server to the local computer, the exception indicating which identification information is required by the server to accept the data packet, and automatically approving the device.

12. The method of claim 11, further comprising:

queuing the data packet in a queue of the local computer;

responsive to the device not being approved and automatically approving the device, receiving the data packet from the queue and storing the data packet in the database.

13. The method of claim 1, further comprising queuing the data packet in the local computer until the data packet is accepted by the server.

14. The method of claim 1, further comprising queuing the data packet in the server until the data packet is accepted by the server.

15. The method of claim 1, wherein the receiving is carried out behind a firewall imposed between the local computer and the server, the throwing including throwing from the server to the device the exception through the firewall.

16. The method of claim 1, wherein the local computer includes the server.

17. The method of claim 1, wherein the configuration information is information relating to the local computer.

18. The method of claim 1, wherein the configuration information is information relating to the device.

19. The method of claim 1, further comprising:

automatically approving at least some of the unrecognized configuration information; and

repeatedly sending the data packet until the server accepts the data packet.

20. The method of claim 1, further comprising queuing the data packet in the local computer or the server until the server accepts the data packet.

21. A non-transitory computer readable storage medium encoded with instructions for directing a controller to perform the method of claim 1.

22. The method of claim 1, wherein the exception is selected from among a plurality of exception types, each exception type indicating a different type of configuration information that is required by the server.
