(54) System for transmitting commands, particularly to motor-driven transport means


(57) 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 (A to H) 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 (A to H) is obtained through a coded signal formed from a sine wave which is sent to the peripheral means through a single conductor.
