System for monitoring the state of a cable through distributed transferometry

A system for monitoring a state of a cable, the system comprising a plurality of transferometry devices each being capable of injecting a test signal at an injection point of the cable and measuring a signal being propagated in the cable at a measurement point of the cable, the transferometry devices being intended to be positioned along the cable at predetermined positions so as to break down the cable into successive sections, the system comprising:

• a control member capable of communicating with the transferometry devices and configured so as to perform at least one transferometry test consisting in injecting a test signal into the cable with a first transferometry device and measuring the test signal after its propagation in the cable with a second transferometry device different from the first transferometry device, the system further comprising:
• a post-processing member capable of communicating with the transferometry devices and configured to compare the measured signal to a reference signal to deduce therefrom an indicator of degradation of a cable section disposed between the first transferometry device and the second transferometry device, the control member being configured to control, according to a predefined test procedure, each transferometry device by activating or deactivating the injection of a test signal into the cable with said device and by activating or deactivating an acquisition of a measurement of a signal being propagated in the cable with said transferometry device,
• wherein the control member is configured to simultaneously activate several tests procedures for several sections of the cable, a test procedure consisting in successively executing the following commands:
• activating the injection of a test signal by a first transferometry device situated at a start of a first section of the cable, and
• activating the acquisition of a signal measurement by a second transferometry device disposed at an end of the first section.
