Embodiment Construction
[0034] figure 1 A device V for detecting an occupied or free state of a track segment G is shown in . The means V has a function for sending the signal SIG in the form of an alternating voltage S Transmitter S feeding rail F of track segment G. In addition, the device V also includes a signal for receiving the signal SIG that will be sent by S Received signal SIG generated by transmission via rail F of track section G E The receiver E.
[0035] corresponds to figure 1 As shown, the track section G is fed with an alternating voltage of frequency f1. In order to be able to reliably distinguish the individual signals, adjacent track sections are operated with alternating voltages of different frequencies f5 or f3. The following assumptions, in figure 1 The device shown in is an audio rail circuit with multiple frequencies in which the transmission signal SIG in the audio range will be S The rails F of the track section G are fed with an alternating voltage in the form of ...
