摘要
The transmission operates with modulated alternating voltages of a train control device, which has on the track side a preset number of modulation frequency generators, corresponding to the signals to be transmitted. The rail vehicles carry receivers, demodulators, and evaluators. For the transmission of a single signal of two individually or simultaneously switchable light signals (LSR, LSG) the control of the generators (140-143) is carried out by three optical couplers (OR1,OR2,OR3). Each coupler comprises a radiation transmitter (OR11) with an optically coupled radiation receiver (OR12). The radiation transmitter of the first coupler, or both transmitters (OR21, OR31) of the second and third coupler, are connected to the circuit (L6,L8) of the signal lamp of one or the other light signal. The radiation receivers (OR12, OR21) of the first two couplers serve for enabling of the associated generators. The receiver (OR32) of the third coupler blocks the first coupler.
