  • Device for detecting the occupied or available status of a track segment and method for operating such a device
    Patent number: 9139211
    Abstract: A device for detecting an occupied or available status of a track segment has a transmitter for feeding in a transmitted signal into the travel rails of the track segment and at least one receiver for receiving a received signal generated by transmitting the transmitted signal via the travel rails of the track segment. In order to simplify commissioning, the device is implemented for varying the frequency of the transmitted signal, for determining a resonant frequency of the transmitted signal, and for adjusting the frequency of the transmitted signal to the determined resonant frequency. A method for operating the device for detecting the occupied or available status of a rail segment is further discussed.
