1. A system for detecting deterioration of or cuts C in a cable for transmitting signals between at least one first device A and at least one second device B, comprising:
said first device A being disposed at a first end of the cable and including at least a transceiver, synchronization means, means for communication between the first device A and the second device B, calculation means connected to the transceiver, the transmitter being adapted to transmit a signal SA from A to B, the receiver being adapted to measure times of non-reception of a signal, said second device B being disposed at a second end of the cable, said second device B including at least the following components: a transceiver, synchronization means, means for communication between A and B, calculation means connected to the transceiver, the transmitter being adapted to transmit a signal SB from B to A, the receiver being adapted to measure times of non-reception of a signal, and wherein the means for communicating times of non-reception of the signals measured at the receivers are adapted to transfer the measured time of non-reception of the signal SB at the first device A and the measured time of non-reception of the signal SA at the second device B to said calculation means, said calculation means being adapted to determine the time tC and the location XC of the fault or the cut in the cable from the measured times of non-reception of signals received at the calculation means. |
