DIRECT VIEW REMOTE CONTROL METHOD FOR WORKINGS MACHINE AND TRANSMITTER AND RECEIVER ASSEMBLY FOR CARRYING OUT SUCH METHOD

摘要

ABSTRACT OF THE DISCLOSUREA direct view remote control method, and acorresponding transmitter and receiver assembly, for rapid andreliable transmission of simultaneous orders to a works machinesuch as for mines and quarries. Orders from a driver areconverted into binary signals ; a sequential binary signal iselaborated therefrom so that each sequence comprisessynchronisation bits with a synchronization binary periodicsignal and information bits occupied by a biphased encoded binarysignal representative of said binary signals ; Amplitude ofcarrier wave is modulated by said sequential binary signal so asto form a remote control signal to be transmitted ; afterreceiption thereof the sequential signal is restored and, throughrecognition therein of the synchronization signal, converted intoappropriate electric signals for the machine.
