Background
The cable is often used for the traction of structures such as bridges to provide traction force, so as to achieve the effect of keeping the stability of the bridge structure and dispersing stress, but because the cable is made of metal materials, the cable is still rusted due to humidity and other reasons in spite of being wrapped by the protective shell, and the structural strength is affected.
To detect the humidity inside the cable, it is used to arrange an optical fiber on the steel wire inside the cable. The existing optical fiber is mainly characterized in that a groove is formed in the outer wall of a steel wire, and then the steel wire is embedded into the groove. However, the fiber grating sensor with only a single linear groove senses non-uniformity of humidity inside the cable; if the steel wire is twisted, the grooves are spiral, so that the induction is uniform, but extra processing steps are added, and the cost and the processing time are increased. Therefore, there is a need for an improvement in such a structure to overcome the above-mentioned drawbacks.
