Abstract

The present invention relates to a system for detecting the presence or absence of a rail vehicle (2) on a track section unit (3) of a track (1), comprising: - a track section unit transmitter (5) generating a BPSK signal that carries a digital message which is transmitted into the track section unit (3) and carries a unique code dependent upon the track section unit (3), and - at least one track section unit receiver (7) of said BPSK signal, the receiver (7) only indicating that the track section unit (3) is clear having received and demodulated a BPSK signal, found that the correlation of the demodulated BPSK signal with the unique code is greater than or equal to a preset threshold and found that said correlation represents a pre-determined minimum proportion of the total energy of the demodulated BPSK signal. The present invention also relates to a method for monitoring such a system.
