Abstract

A method is provided for remotely controlling a supply of power to a plurality of electrical appliances. In response to attaching a plug of a first electrical appliance of a plurality of electrical appliances to a first socket of the one or more sockets connected to a main power supply, a control system activates a transceiver at a first of the first socket and the plug; stimulates, via the transceiver, a tag at a second of the first socket and the plug to determine a unique identifier of the tag. The control system receives the unique identifier of the tag from the transceiver and uses the unique identifier to activate/deactivate the transceiver which connects/disconnects the main power supply from the first electrical appliance.

Claims

1. A method for remotely controlling a supply of power to a plurality of electrical appliances, wherein the plurality of electrical appliances are connectable to a main power supply via one or more sockets, the method comprising:

in response to attaching a plug of a first electrical appliance of the plurality of electrical appliances to a first socket of the one or more sockets, a control system;

activating a transceiver located at one of the first socket and the plug of the first electrical appliance;

stimulating, via the transceiver, a tag located at a next one of the first socket and the plug of the first electrical appliance, wherein the tag is in close proximity to the transceiver and is capable of receiving communication from the transceiver; and

interrogating, via the transceiver, the tag to determine a unique identifier of the tag, wherein the unique identifier enables the control system to control whether power is applied to the transceiver;

the control system receiving, from the transceiver, the unique identifier of the tag;

in response to the control system receiving an instruction to disconnect power to the first electrical appliance, deactivating the transceiver, wherein deactivation of the transceiver deactivates the plug of the first electrical appliance at the first socket and disconnects the main power supply from the first electrical appliance; and

in response to the control system receiving an instruction to connect power to the first electrical appliance, activating the transceiver, wherein activation of the transceiver stimulates the tag and activates the plug of the first electrical appliance at the first socket and connects the main power supply to the first electrical appliance.

2. The method of claim 1, wherein:

the transceiver is powered by the main supply;

the plug of the first electrical appliance is powered at the first socket only while the transceiver is active and the plug of the first electrical appliance is attached to the first socket; and

the tag allows a current to flow through the plug of the first electrical appliance to the first electrical appliance while the tag is stimulated.

3. The method of claim 1, wherein:

the tag includes an inductor that is coupled to a first relay switch;

the first relay switch is wired in series with and located in between the appliance and the main power supply; and

said stimulating the tag via the transceiver causes the inductor to hold the first relay switch closed, while the tag is being stimulated by the transceiver.

4. The method of claim 1, wherein:

the first socket further comprises a microcontroller that receives instructions from the control system;

the microcontroller is communicatively coupled to the control system via a wireless connection,

the microcontroller is coupled to a second relay switch;

the microcontroller receives instructions from the control system to provide power to or disconnect power from the transceiver by closing or opening of the second relay switch;

the microcontroller and the transceiver are connected in series; and

the microcontroller and the transceiver are wired parallel to a live wire and a neutral wire of the first socket.

5. The method of claim 1, wherein the control system further comprises a web portal having a network connection to each of the one or more sockets.

6. The method of claim 1, wherein the transceiver and the tag are one of:

radio-frequency identification (RFID) devices and near field communication (NFC) devices.
