Problems solved by technology

The method to solve this contradiction is to introduce the reference optical fiber as the standard signal and the sensing optical fiber according to the different physical quantities, adding a sensitive coating to form the sensing signal, which is convenient for comparison and signal analysis. Obviously, there are problems that are not easy to engineer and commercialize.

Embodiment Construction

[0024] The cabling structure of the distributed optical fiber sensor according to the present invention will be described in detail below according to the accompanying drawings.

[0025] The figure-8-like optical cable [300] is composed of a small-radius sensing optical cable [200], a large-radius transmission reference optical cable [100], and the large-radius transmission reference cable [100] and the small-radius sensing cable [200] are connected in one process, Together they form a distributed sensing fiber optic cable [300], and the distributed sensing fiber optic cable [300] can be composed of a distributed ( figure 1 ), parallel ( figure 2 ), compact ( image 3 ) or inline ( Figure 4 ).

[0026] For the transmission reference optical cable [100], its composition can be a layered structure ( Figure 5 ), or a skeleton structure ( Image 6 ), or a central beam tube structure ( Figure 7 ), and its composition is shown in the figure.

[0027] Wherein the strength ...

Abstract

This invention relates ton one distribution fiber sensor cable structure, which comprises sensor cable and transmission reference cable section 8 shape cable, wherein, the sensor cable small radium and large radium transmission reference cable are connected together to form the distribution sensor fiber cable and to form distributed and parallel and compact or imbedded structure; the transmission reference cable forms can be of layer twisting structure or skeleton structure or center beam structure; the sensor cable forms skeleton structure or center beam structure.

Description

technical field [0001] The invention relates to a cabling structure of a distributed optical fiber sensor. Background technique [0002] Distributed fiber optic sensors have attracted great attention because they can measure vibration, pressure, stress, temperature, radiation and other quantities in the radial space physical field. According to the principle that the intensity, phase, polarization state and frequency of the light transmitted by the optical fiber are modulated by physical quantities such as vibration, pressure, temperature, radiation, etc. in the space physical field, a large number of distributed optical fiber sensing models are proposed. [0003] At the same time, a method is proposed to locate the distribution points where the intensity, phase, polarization state, and frequency of the light transmitted by the optical fiber are modulated by physical quantities such as vibration, pressure, stress, temperature, radiation, etc. Optical time domain method, dif...
