Method and apparatus for identifying an electric load via RFID tag associated with a power plug

摘要

A method and apparatus for identifying a load powered by an intelligent AC outlet, sub outlet and socket via an AC plug including an attached or otherwise associated RFID tag selected from a group of RFID tags structured to fit a given standard AC plug size and shape for attachment to said plug about the plug power pins opposite and facing an RFID antenna included in said intelligent outlet. The tags can be pre-coded or individually coded to identify the load powered via said plug.

1. An RFID tag assigned with a code for identifying a given type of an electrical appliance by attachment to a front surface about the power pins of an AC power plug powering said appliance through an AC socket of an intelligent AC outlet, said RFID tag comprising a low frequency band chip and a coil structured to fit said front surface and power pins of a given standard AC power plug size and shape with said coil directly facing an RFID antenna included in said AC socket opposite said coil;
said intelligent AC outlet including one of said AC socket and plurality of AC sockets comprising one of a built-in and a connected circuit for measuring the power consumed through each AC socket, one of read and read/write RFID circuit and one of a single and a plurality of said RFID antenna, said coil is structured to limit the RFID code signal of said low frequency band for communicating in close proximity with only one said RFID antenna and preventing stray signals from reaching said plurality of antennas.
