SYSTEMS AND METHODS FOR POWERING AND COMMUNICATING WITH WIRELESS SENSOR DEVICES USING BUILDING ELECTRICAL WIRING

摘要

A system and method for powering and communicating with wireless sensors are provided. One system includes a radio-frequency (RF) transmitter configured to transmit at least one of RF power signals or RF communication signals and a coupling circuit configured to couple the RF transmitter to electrical wiring to allow transmission of the RF power signals or the RF communication signals through the electrical wiring. The system also includes a connector configured to couple the RF transmitter to a power outlet of the electrical wiring.

主权项

1. A system comprising:
a radio-frequency (RF) transmitter configured to transmit at least one of RF power signals or RF communication signals, wherein the RF transmitter is a radio-frequency identification (RFID) reader; and an interface sub-system configured to allow the RFID reader to use electrical wiring as an RF antenna. the interface sub-system comprising:
a coupling circuit configured to couple the RFID reader to the electrical wiring to allow transmission of at least the RF communication signals through the electrical wiring from the RFID reader to one or more RFID tagsa connector configured to couple the RFID reader to a power outlet of the electrical wiring; andan AC power adapter configured to convert AC power received from the power outlet to DC power for powering the RFD reader.
