System and method for single conductor power, control, and feedback system

摘要

To control multiple electronic circuits organized in a series configuration, this document introduces a single-wire power, control, and feedback system. Specifically, individually controlled electronic circuits are arranged in a series configuration that is driven by a control unit located at the head of the series. The head-end control unit provides both electrical power and control signals down a single wire to drive all of the electronic circuits in the series in a manner that allows each electronic circuit to periodically draw power from the single wire and receive control information. Each electronic circuit in the series may communicate back to the head-end control unit by drawing power or not during a specified time slot.

主权项

1. A digitally controlled power distribution system, said digitally controlled power distribution system comprising:
a power supply for supplying an electrical current on a single conductor line; a line driver circuit, said line driver modulating a clocked signal onto said electrical current on said single conductor line; and more than one controlled circuit unit coupled in a series arrangement to said single conductor line, each said controlled circuit unit periodically drawing said electrical current on said single conductor line by unshunting said electrical current, each said circuit unit normally shunting said electrical current when not drawing said electrical current wherein one of said more than one controlled circuit units shunts or unshunts said electrical current during a designated time slot of said clocked signal to communicate back to said line driver circuit.
