Systems and methods for direct current system digital carried message conveyance
View Patent ↗The systems and methods of the present invention provide for conductive emissions communication without requiring dedicated communications wires. The systems and methods have the capability to send digital messages over the same wires that are used to power DC, systems. Hardware filter circuits are combined with advanced algorithms in a communications control chip to permit the elimination of the dedicated wires, thereby needing zero additional wires to accomplish the task of digital control.
1. A method of transmitting a digital communication comprising
transmitting a command signal directly over a direct current (DC) system power line from an input device, through an output device, and to a load without the use of a designated communications line;
processing the command signal, the command signal comprising a binary serial signal comprising a group of three or less bytes, wherein one of the bytes identifies a group of targets to receive a message, one of the bytes identifies that a message is to be transmitted, and one of the bytes corresponds to a designated command function;
assigning a series of individual modules into a group, transmitting said binary signal series to a plurality of groups, said groups receiving said binary signal series and interpreting said binary signal series to determine whether said binary signal series applies to said group, and if said binary signal series applies to said group, activating or deactivating an output based on the content of said binary signal series; and
filtering interfering signals from the command signal.
