Abstract
Systems and methods are provided to transmit a data encoded power signal to addressable devices. A data signal includes address and command data that varies between logical states. A controller provides a low loss rectified power signal. The controller further provides data within the power signal by forming a positive polarity rectified power waveform corresponding to data in a first state and a negative polarity rectified waveform signal corresponding to data in a second state using substantially loss-less circuitry.
Claims23
A lighting control system configured to power and modify a behavior of a plurality of lighting modules, each lighting module including one or more LED lights and being serially addressable over a two-wire communication network, the lighting control system comprising:
- a master lighting controller comprising an operator interface that accepts user input regarding the behavior of the one or more LED lights of the plurality of lighting modules and outputs command and address data having a first protocol, the command and address data responsive to the user input, the master lighting controller further comprising a first power supply that encodes the command and address data having the first protocol onto a power waveform according to a second protocol to generate a first data encoded power signal that includes the command and address data having the second protocol for transmission over a first two-wire communication network to power and control a first portion of the plurality of lighting modules according to the user input, the second protocol different from the first protocol, each lighting module of the first portion comprising a microcontroller to decode the command and address data having the second protocol from the first data encoded power signal into a format usable to control the one or more LED lights;
- a protocol converter separate from the plurality of lighting modules and the master lighting controller, the protocol converter operably coupled to the first two-wire communication network to receive the first data encoded power signal, the protocol converter comprising processing circuitry to convert the first data encoded power signal having the second protocol to the command and address data having the first protocol and a transceiver to transmit the command and address data having the first protocol over a communication path;
- and
- a slave lighting controller separate from the protocol converter, the plurality of lighting modules, and the master lighting controller, wherein the protocol converter and the slave lighting controller are operably coupled to the communication path to receive the command and address data having the first protocol and encode the command and address data having the first protocol onto a power waveform according to the second protocol to generate a second data encoded power signal that includes the command and address data having the second protocol for transmission over a second two-wire communication network to power and control a second portion of the plurality of lighting modules according to the user input, each lighting module of the second portion comprising a microcontroller to decode the command and address data having the second protocol from the second data encoded power signal into the format usable to control the one or more LED lights, wherein the second protocol utilized by the master lighting controller is the same as the second protocol utilized by the slave lighting controller.

A protocol converter configured to relay information from a master lighting controller to a slave lighting controller, the protocol converter comprising:
- a conditioning circuit operably coupled to a first two-wire communication network to receive a first data encoded power signal from a master lighting controller, wherein the master lighting controller accepts user input to control a behavior of a plurality of lighting modules, provides command and address data having a first protocol, and encodes the command and address data having the first protocol onto a power waveform according to a second protocol that is different from the first protocol to form the first data encoded power signal that includes the command and address data having the second protocol, the command and address data responsive to the user input;
- processing circuitry to convert the first data encoded power signal that includes the command and address data having the second protocol to the command and address data having the first protocol;
- and
- a transceiver to transmit the command and address data having the first protocol over a communication path to at least one slave lighting controller that is separate from the plurality of lighting modules and the master lighting controller, wherein the at least one slave lighting controller receives the command and address data having the first protocol, encodes the command and address data having the first protocol onto the power waveform according to the second protocol to generate a second data encoded power signal that includes the command and address data having the second protocol for transmission over a second two-wire communication network to power and control a plurality of lighting modules, wherein each lighting module of the plurality of lighting modules comprises a microcontroller to decode the command and address data having the second protocol from the second data encoded power signal into the format usable to control one or more LED lights.
