Control system for the independent operation of a plurality of model vehicles such as model railway trains, model cars etc., which are supplied with power via a common circuit

摘要

The invention relates to a control system for the independent operation of a plurality of model railway trains on one track. In order to reduce the size of the receiver, it is provided for the data outputs to be supplied to a summing point via in each case one resistor, which summing point is preferably connected via a capacitor to earth. The impedance values in the data outputs form an impedance row, the impedance value in one data output being selected in each case to be approximately double the value of the adjacent, lower data output. Via a comparator stage, which compares the obliterated sum signal with a sawtooth-wave form voltage, a pulse-width-modulated output signal is obtained for controlling power transistors in the power circuit of the motor.
