“…Corresponding initial conditions are set according to different load loading methods. Substituting the above initial values and the strain values of the fiber cores 1-1 and 2-2 obtained by simulation into equations (19) and (20), the coordinates of each measuring point on the deformed flexible substrate can be obtained. Figure 12 compares the actual shape and the reshaped flexible substrate.…”

“…The first measurement of curvature made using FBGs written in separate cores of a multicore optical fiber was reported by Gander et al [16]. With the advent and diffusion of space division multiplexing and wavelength division multiplexing, quasi-distributed shape sensing was also finally demonstrated [17][18][19][20]. An innovative method was proposed based on the numerical resolution of a set of Frenet-Serret equations to reconstruct complex three-dimensional fiber shapes as a continuous parametric solution [21].…”

Intelligent perception of a scraper conveyor straightness and attitude monitoring of mechanical supporting equipment in the stope have practical and theoretical values for mining. This study proposed an optical fiber curvature sensor and a scraper conveyor’s curve reconstruction method. The optical fiber curvature sensor comprises the fiber grating strain sensing optical cables, the flexible substrate, and the packaging material. The coordinate positions of each monitoring point are obtained through the strain-curvature conversion relationship and the slope recurrence algorithm, and then the reconstruction curve is obtained by fitting. The finite element simulation verifies the feasibility of the curve reconstruction method used for the deformation monitoring via optical fiber curvature sensors. The reconstruction error analysis results show that the root mean square error of reconstructions for two kinds of 2D plane bending and 3D space bending are 2.98, 1.89, and 3.13%, respectively. Their mean absolute errors are 8.9, 3.56, and 9.82 mm, respectively, verifying the feasibility and high accuracy of the proposed curve reconstruction equation. The research results provide a theoretical basis for the shape perception and straightening control of scraper conveyors in the intelligent working surface.

“…Vigilant monitoring of plastic water pipelines is imperative, particularly in the context of strain surveillance within the pipeline framework. Cutting-edge, expansive distributed intelligent sensing components, exemplified by Fiber Bragg Grating (FBG) sensors, lay the groundwork for the evolution of health monitoring systems for pipeline structures [3,4]. FBG strain sensors, characterized by robust immunity to electromagnetic interference, elevated precision, commendable longevity, and the capacity for distributed measurement, are instrumental in this regard.…”

The metrological performance of FBG strain sensing systems is a critical premise for the precision of plastics water support pipeline structural deformation measurement, but the strain transfer loss of FBG attached on the plastics pipe subjected by dynamic force is unclear. This paper presents the first study on the effects of strain transfer between FBG, and acrylate polymer blended with poly resin (ABR)pipe sheets loaded by static and dynamic force. Theoretical methods of dynamic strain transfer theory combine with the exponentially decaying sinusoidal shock force time course is deduced and various dynamic parameters sensitivities studies are carried out, as well as that of the geometric parameters. The result of the dynamic theory is compared with the calibration test outcomes, while the ASTR of FBG attached on ABR sheet is compared with distributed optical fiber sensors (DOFS) and other pipe materials such as PVC, concrete, and steel. Results show that the ASTR of FBG is more accurate than that of the DOFS, and the grows of ASTR depending on the paste length of FBG, the Young's modulus of the middle materials, the thickness of the middle materials and attenuation coefficient. Paste length produced the largest increase, yet the magnitude and loading speed of the external force has unexpectedly little effect on ASTR. FBG seem low error, insensitive with dynamic force and independent with the material of matrix, and this demonstrates benefits that are stronger across the board than DOFS. This is not currently recognized by standards or by most reported studies.
