Abstract
A redundant digital address and function code is generated at a central location and transmitted through a signal circuit or an A.C. power distribution circuit to a plurality of receiver locations. At each addressed receiver location, the encoded function is performed to control selected loads in a predetermined manner. A signal may be transmitted back to the central location for controlling a pre-programmed combination of loads in response thereto.
Claims2
A method for performing a selected electrical function at a selected one of a plurality of remote locations from a central location comprising:
- redundantly generating a predetermined number of digital words at said central location;
- transmitting the generated words to each of said remote locations;
- decoding each of said transmitted words at each of said remote locations;
- detecting a predetermined address in each of said digital words at said selected remote location;
- performing said selected function at said selected remote location when identical digital words having said predetermined address have appeared at said selected remote location a predetermined number of times out of the number of times said digital words have been redundantly generated at said central location;
- and
- transmitting from said selected remote location to said central location a control signal intended to control a pre-programmed combination of loads responsive to said control signal.
