Title:
FIBER GRATING SENSOR INSERT FOR SMART PLASTIC PIPE, AND IMPLANTATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/010830
Kind Code:
A1
Abstract:
A fiber grating sensor insert for a smart plastic pipe, comprising: a base resin (7), a fiber grating temperature sensor (1), a fiber grating strain sensor (2) and reinforcing fibers (6); the fiber grating temperature sensor (1) and the fiber grating strain sensor (2) are placed side-by-side in parallel, the two being provided with multiple grating units (4); the positions of the grating units (4) correspond to each other so as to jointly form a grating pair having the function of monitoring both temperature and strain. The fiber grating temperature sensor and the fiber grating strain sensor are embedded within the base resin (7), the base resin also being filled with the reinforcing fibers; the reinforcing fibers are evenly distributed in parallel within a strip-shaped insert of the fiber grating sensor so as to support the entire frame of the strip-shaped insert of the fiber grating sensor. Further disclosed are an implantation system for the strip-shaped insert of the fiber grating sensor and a method for preparing the smart plastic pipe. According to the present invention, by combining the conventional processing technology of continuous extrusion of a plastic pipe material and fiber-optic communication technology, fabricated smart plastic pipes may monitor parameters, such as temperature, strain and pressure, online and in real-time.
