Abstract
The present invention relates to a device for monitoring a magnetic brake on rail vehicles, the magnetic brake being connected to a source of voltage for current supply, the device comprising switching on and monitoring of the brake magnet current and the monitoring device including a determining device and an evaluating device, the determining device continuously monitoring the function of the circuit for the current supply to the magnetic brake during braking, and recording the current and/or voltage profile. Here, the evaluating device determines the placement of the magnetic brake on the rail on the basis of the recorded current and/or voltage profile by detection of two zero crossings of the first derivative of the current and/or voltage profile.
