Abstract

The present disclosure is directed to an intelligent electronic device (IED) configured for use in an Internet of Things (IoT) environment. The IoT environment of the present disclosure may include one or more objects or things in addition to the IED coupled together via a network, where each device is configured for IoT communication.

First claim

What is claimed is:

1 . An intelligent electronic device (IED) comprising:
at least one sensor coupled to an electrical distribution system, the at least one sensor configured to measure at least one parameter of the electrical distribution system and generate at least one analog signal indicative of the at least one parameter; at least one analog-to-digital (A/D) converter configured to receive the at least one analog signal and convert the at least one analog signal to at least one digital signal; at least one processor configured to receive the at least one digital signal and calculate at least one power parameter of the electrical distribution system; and a network communication card configured for Internet of Things (IoT) communication and coupled to a network, wherein the network communication card receives at least one first request from at least one first device coupled to the network requesting a list of all available resources of the IED, wherein the at least one processor generates at least one first response including a list of all available resources of the IED to the at least one first request and the network communication card sends the at least one first response to the at least one first device.

2 . The IED of claim 1 , wherein the network communication card receives at least one second request from the at least one device requesting information associated with at least one resource of IED, and the at least one processor generates at least one second response to the at least one first request with the information related to the at least one resource, and the network communication card sends the at least one second response to the at least one first device.

3 . The IED of claim 2 , wherein the at least one resource is at least one power parameter calculated by the at least one processor.

4 . The IED of claim 2 , wherein the at least one second request includes a condition, and the at least one processor is configured include only information satisfying the condition in the at least one second response.

5 . The IED of claim 1 , wherein the at least one processor generates at least one second request requesting information associated with at least one resource from the at least one first device, and the network communication card sends the at least one second request to the at least one first device and receives at least one second response from the at least one first device including information associated with the at least one resource of the at least one first device.

6 . The IED of claim 1 , wherein the network communication card receives at least one second request requesting a confirmation that a requested resource exists on the IED, and the at least one processor determines if the requested resource exists on the IED and generates at least one second response confirming or denying the existence of the requested recourse, and the at least one communication card sends the at least one second response to the at least one first device.

7 . The IED of claim 1 , wherein the network communication card receives at least one second request from the at least one first device to add the at least one first device to a notification list stored in a memory of the IED, the notification list associated with receiving periodic notifications including information associated with at least one resource of the IED, and the at least one processor is configured to periodically generate notifications including information associated with the at least one resource at predetermined intervals, and the network communication card sends each notification to the at least one first device at the predetermined intervals.

8 . The IED of claim 7 , wherein the network communication card receives at least one third request from the at least one first device requesting the at least one first device to remove the at least one first device from the notification list, and the at least one processor removes the at least one first device from the at least one notification list in response to the at least one third request.

9 . The IED of claim 1 , wherein the network communication card receives at least one second request from the at least one first device requesting information associated with at least one resource of the IED and the at least one processor determines that the IED does not currently have the requested information, and scheduling at least one second response to be sent to the at least one first device when the requested information becomes available.

10 . The IED of claim 1 , wherein the IoT communication operates in accordance with at least one of Constrained Application Protocol, Simple Object Access Protocol, Constrained RESTful Environment (CoRE), MQTT, Data Distribution Service Protocol, Extensible Messaging and Presence Protocol, Advanced Message Queuing Protocol, Mosquito, M3DA, Internet Protocol for Smart Objects (IPSO), and/or Wolfram.

11 . The IED of claim 1 , wherein the at least one first request is at least one of a GET, HEAD, POST, PUT, DELETE and/or CONNECT command.

12 . The IED of claim 1 , wherein the at least one first response is at least one of a GET, HEAD, POST, PUT, DELETE and/or CONNECT command.

13 . A method comprising:
connecting, by a network communication card, to a network, the network communication card configured for Internet of Things (IoT) communication; receiving, by the network communication card, at least one first request from at least one first device connected to the network requesting a list of all available resources of an intelligent electronic device (IED), the at least one first device also configured for IoT communication; generating, by at least one processor, at least one first response including a list of all available resources of the IED to the at least one first request; and sending, by the network communication card, the at least one first response to the at least one first device.

14 . The method of claim 13 , further comprising:
receiving, by the network communication card, at least one second request from the at least one first device requesting information associated with at least one resource of IED; generating, by the at least one processor, at least one second response to the at least one first request with the information related to the at least one resource; and sending, by the network communication card, the at least one second response to the at least one first device.

15 . The method of claim 14 , wherein the at least one resource is at least one power parameter of an electrical distribution system that is calculated by the at least one processor.

16 . The method of claim 14 , wherein the at least one second request includes a condition, and the at least one processor is configured include only information satisfying the condition in the at least one second response.

17 . The method of claim 13 , further comprising:
generating, by the at least one processor, at least one second request requesting information associated with at least one resource from the at least one first device; sending, by the network communication card, the at least one second request to the at least one first device; and receiving, by the network communication card, at least one second response from the at least one first device including information associated with the at least one resource of the at least one first device.

18 . The method of claim 13 , further comprising:
receiving, by the network communication card, at least one second request requesting a confirmation that a requested
