Abstract

To determine if a track section (1) is covered by a wagon or foreign object (6) detectors (D1-D5) are arranged as freely selectable intervals along the track. The detectors use an NMR principle with transmitted pulse packets detected by the detectors and response signals converted into the frequency domain using a Fourier transform. An object within range of a detector alters the magnetic field such that largely no response is generated. <??>After Fourier transformation of the response signals, the response signals are assigned to the detectors. Thus the absence of a response signal can be used to indicate the precise location of a possible obstacle on the track. <??>An Independent claim is also included for a corresponding system.
