Abstract

The present invention provides a system including a utility network including a product distribution pathway for delivering a product, a plurality of electronic utility devices associated with the utility network to monitor at least one parameter associated with the product distribution pathway, and a management processor in communication with the devices and operable to poll at least a subset of the electronic utility devices in response to an input to evaluate performance of one of the utility network and the system in response to information relating to the at least one parameter. The evaluation can include a rule-based analysis of one of the parameter and the information relating to the parameter.

Claims

1. A product delivery monitoring system comprising:

a plurality of electronic devices configured to monitor delivery of a product; and

a management processor configured to;

enter a first polling mode;

poll the plurality of electronic devices by transmitting a first polling message to the plurality of electronic devices via a first message format associated with the first polling mode,

receive an input indicating a potential outage, and

in response to receiving the input, enter an exception polling mode, and

poll a subset of the plurality of electronic devices included in the plurality of electronic devices by transmitting a second polling message to the subset of the plurality of electronic devices via a second message format associated with the exception polling mode, wherein the second polling message is shorter than the first polling message.

2. The system of claim 1, wherein, when in the exception polling mode, the management processor is further configured to suspend the first polling mode.

3. The system of claim 1, wherein, when in the exception polling mode, the management processor is further configured to operate the first polling mode at a reduced rate.

4. The system of claim 1, wherein, when in the exception polling mode, the management processor is further configured to poll a group of electronic devices included in the plurality of electronic devices that are suspected of not receiving the product.

5. The system of claim 1, wherein, when in the exception polling mode, the management processor is further configured to poll a group of electronic devices included in the plurality of electronic devices that are neighboring an electronic device suspected of not receiving the product.

6. The system of claim 1, wherein, when in the exception polling mode, the management processor is further configured to:

operate according to a predetermined set of rules; and

poll a plurality of pre-selected electronic devices included in the plurality of electronic devices.

7. The system of claim 6, wherein the pre-selected electronic devices have been rated as reliable.

8. The system of claim 1, further comprising a gateway device linking the management processor to the plurality of electronic devices.

9. The system of claim 8, wherein the gateway device enters an exception polling mode following a transition from AC power to DC power.

10. The system of claim 1, wherein the management processor remains in the exception polling mode for a period of time following a determination that an outage is over.

11. The system of claim 1, wherein the management processor periodically enters the exception polling mode to verify that an outage has not occurred.

12. The system of claim 1, wherein the input comprises a health exception unicast message transmitted by a first electronic device included in the plurality of electronic devices.

13. The system of claim 12, wherein an intermediate electronic device proxies and coalesces a plurality of health exception messages and correlates the plurality of health exception messages into a single health exception message representing a neighborhood of electronic devices included in the plurality of electronic devices.

14. The system of claim 1, wherein an electronic device included in the plurality of electronic devices responds to the second polling message with at least one of a local health indication and a neighborhood health indication.

15. The system of claim 1, wherein the management processor is further configured to evaluate responses in the exception polling mode based on a historical performance of the subset of the plurality of electronic devices.

16. A method of polling a plurality of electronic devices associated with a product delivery system by a network management center having an outage detection module and a management module, the method comprising:

entering a first polling mode;

polling, by the network management center, the plurality of electronic devices by transmitting a first polling message to the plurality of electronic devices via a first message format associated with a first polling mode;

receiving, at the network management center, an input indicating a potential outage; and

in response to receiving the input, entering a second polling mode, and polling, by the network management center, a subset of the plurality of electronic devices included in the plurality of electronic devices by transmitting a second polling message to the subset of the plurality of electronic devices via a second message format, wherein the second polling message is shorter than the first polling message.

17. The method of claim 16, further comprising suspending the first polling mode when in the second polling mode.

18. The method of claim 16, further comprising reducing a rate at which the first polling mode operates when in the second polling mode.

19. The method of claim 16, further comprising, when in the second polling mode, polling a group of electronic devices included in the plurality of electronic devices that are neighboring an electronic device suspected of not receiving the product.

20. The method of claim 16, further comprising rating a subset of the plurality of electronic devices as highly reliable based on the first polling mode, and polling the subset of the plurality of electronic devices in the second polling mode.

21. The method of claim 16, further comprising remaining in the second polling mode for a period of time following a determination that an outage is over.

22. The method of claim 16, wherein the input comprises a health exception unicast message transmitted by a first electronic device included in the plurality of electronic devices.

23. The method of claim 22, further comprising proxying, coalescing, and correlating a plurality of health exception message by an intermediate electronic device into a single health exception message representing a neighborhood of electronic devices included in the plurality of electronic devices.
