ABSTRACT:
A direct view remote control method, and a corresponding transmitter and receiver assembly, for rapid and reliable transmission of simultaneous orders to a works machine such as for mines and quarries. Orders from a driver are converted into binary signals; a sequential binary signal is elaborated therefrom so that each sequence comprises synchronization bits with a synchronization binary periodic signal and information bits occupied by a biphased encoded binary signal representative of said binary signals; Amplitude of carrier wave is modulated by said sequential binary signal so as to form a remote control signal to be transmitted; after reception thereof the sequential signal is restored and, through recognition therein of the synchronization signal, converted into appropriate electric signals for the machine.
