Monitoring method and system for detecting the torsion along a cable provided with identification tags

摘要

A method for monitoring the torsion of a cable includes the steps of: providing a cable having an outer surface and extending along a longitudinal direction, the cable being provided with at least one identification tag, preferably an RFID tag, arranged in a tag angular position in a cross-sectional plane taken transverse to the longitudinal direction, the at least one tag storing a tag identification code and being capable of transmitting a tag electromagnetic signal; interrogating the at least one identification tag to receive the tag electromagnetic signal, and detecting the tag electromagnetic signal, wherein the step of detecting the tag electromagnetic signal includes the step of reading the tag identification code and determining the tag angular position of the at least one identification tag. A torsion monitoring system of a cable includes at least one identification tag.

1. A method for monitoring torsion of a cable comprising:
providing a cable having an outer surface and extending along a longitudinal direction, the cable being provided with a plurality of identification tags arranged along a cable length in respective tag angular positions in cross-sectional planes taken transverse to the longitudinal direction, each tag storing a tag identification code and being capable of transmitting a tag electromagnetic signal; interrogating at least one identification tag to receive the tag electromagnetic signal; and detecting the tag electromagnetic signal for monitoring torsion of the cable, wherein detecting the tag electromagnetic signal comprises reading the tag identification code and determining the tag angular position of the at least one identification tag.
