Abstract
A system is described for transmitting a plurality of commands to peripheral means, particularly to motor-driven transport means and principally to automatic carriages on rails for the overhead conveyance of material, which provides a main station that generates and sends command signals to the peripheral means which house on-board reception and handling circuits for the command signals. The main characteristic lies in the fact that the plurality of commands is obtained through a coded signal formed from a sine wave which is sent to the peripheral means through a single conductor.
Claims23
A system for the transmission of a plurality of commands to peripheral means, including:
- a main station that generates and sends command signals through a single conductor to the peripheral means which house on-board circuits for receiving and handling the command signals, wherein said plurality of commands is obtained by means of a coded signal formed from a sine wave;
- and
- electrical supply conductors which provide an electrical supply to the peripheral means and a conductor connected to earth, for constituting a return path for said command signals, wherein said single conductor is supplementary to said electrical supply and return path conductors;
- and
- wherein the sine wave is formed from the mains voltage of the electrical supply.
