主 题：Strain sensor array fiber grating composite material monitoring pipeline
摘 要：Pipelines are one of the most important modern energy transportation methods,used especially for the transportation of certain dangerous energy media materials such as crude oil,natural gas,and chemical raw *** requirements have been put forward for the health monitoring and early security warning of pipelines because of the large-scale and complicated development trend of the pipe network *** achieve an accurate assessment of the health conditions of pipeline infrastructure,obtaining as many precise operating parameters as possible,particularly at some critical parts of the pipeline,is ***,a novel type of fiber grating strain sensor array is proposed herein to monitor the pipeline hoop *** sensor utilizes fiber grating characteristics such as light weight,corrosion resistance,remote transmission,and strong environmental *** fiber containing the grating measurement points is implanted into the composite material to complete the sensitization encapsulation and protection of the bare fiber *** design of the sensor array fulfills the requirements for monitoring pipeline mass data,making it easy to form a pipeline health monitoring sensor *** sensor sensitivity is researched by using a combination of theoretical and experimental analysis.A sensitivity test,as well as linearity and stability tests,are performed on the *** experimental results show that the average sensitivity of the sensor is 14.86 pm/με,and the error from the theoretical calculation analysis value is 8.75%.Due to its high reliability,good linear response and long-term stability,and the ability to reflect the exact strain change of the outer wall of the pipeline,the designed sensor can support longterm online pipeline *** fiber grating sensor array network has successfully realized the monitoring of the pipeline’s internal operation by using external strain *** addition to the performance benefits,there are other
