Abstract

The present disclosure relates to a plug load management system having automatic and dynamic load detection, meaning it has the ability to identify devices that are plugged into outlets of a building and determine the location of the plug load down to the specific outlet. When a device is moved, the plug load management system can determine this change and update accordingly.

Claims (50)

1. A system for plug load management, the system comprising:

a tag connected to a receptacle comprising an identifier assigned to the receptacle;

a reader connected to the plug load; and

a processor; wherein:

the plug load is connected to the receptacle,

the tag is configured to provide the identifier to the reader,

the plug load is configured to send the identifier to the processor,

the processor is configured to determine the receptacle the plug load is plugged in to based on the identifier.

2. The system of claim 1 , wherein:

the tag comprises a radio frequency identification (RFID) tag, and

the reader comprises a RFID reader.

3. The system of claim 1 , wherein:

the receptacle comprises an electrical outlet.

4. The system of claim 1 , wherein:

the receptacle comprises a universal serial bus (USB) outlet.

5. The system of claim 1 , wherein the processor contains a database which associates the identifier with the receptacle.

6. The system of claim 1 , wherein the plug load comprises a smart device capable of communicating with the processor using a form of wireless communication.

7. The system of claim 1 , wherein the processor is configured to send an instruction to the plug load.

8. A system for plug load management, the system comprising:

a plug load having a power over ethernet (PoE) connector;

a PoE receptacle having an identifier; and

a processor; wherein:

the plug load is connected to the PoE receptacle via the PoE connector,

the PoE receptacle is configured to communicate the identifier to the plug load,

the plug load is configured to communicate the identifier to the processor, and

the processor is configured to determine the receptacle based on the identifier.

9. The system of claim 8 , wherein the processor contains a database which associates the identifier with the receptacle.

10. The system of claim 8 , wherein the plug load comprises a smart device configured to communicate with the processor using a form of wired communication.

11. the system of claim 8 , wherein the processor is configured to send an instruction to the plug load.

12. A method of plug load management, the method comprising:

providing an identifier via a tag to a reader when a plug load is connected to a receptacle;

communicating the identifier to a processor via the plug load;

identifying the receptacle to which the plug load is connected based on the identifier; and

sending an instruction to the plug load.

13. The method of claim 12 , wherein the providing comprises using a form of near field communication (NFC).

14. The method of claim 13 , wherein:

the form of NFC comprises radio frequency identification (RFID).

15. The method of claim 12 , further comprising before the providing:

recording the identifier and the receptacle in a database within the processor.

16. The method of claim 15 , wherein the determining comprises:

receiving the identifier; and

searching the database for the identifier; wherein:

the database connects the identifier to the receptacle.

17. The method of claim 15 , wherein the plug load comprises a smart device capable of communicating with the processor wirelessly.

18. The method of claim 12 , wherein the sending comprises:

directing the plug load to reduce its energy usage.

19. The method of claim 12 , wherein the sending comprises:

directing the plug load to power off.

20. The method of claim 12 , wherein the sending comprises:

directing the plug load to enter standby mode.
