Vehicle device for inductive train control

摘要

The device has at least one active oscillation circuit for position-dependent coupling with at least one trackside magnet within a passive oscillation circuit, with detection of the duration of the resulting resonance current reduction, for comparison with a reference value, for initiating a given reaction. The signalling of the inductive control is provided by a monostable multivibrator (M1,M2) controlled by voltage pulses obtained from the half- or full-wave of the resonance current.
