摘要
A device is configured to detect whether a track section is occupied or free. The device includes at least one transmitter on the vehicle side, and pairs of receivers on the track side, which are disposed at the ends of the track section, each having first and second receivers disposed at a distance in the track direction. The receivers receive signals from the transmitter as the vehicle passes. They are connected to an analysis unit. In order to ensure exact association between the track section ends and the current vehicle position, the invention provides that for a coupling range between the transmitter and the receiver, plus a maximum driving segment, which results from a minimum pulse duration of the receivers and a maximum segment speed, a response of the receivers during passage is preset such that the responses of the receivers of the receiver pair overlap in the event of increase of the coupling range due to an error.
