Analysis on Structural Health Monitoring System of High-Pile Wharf Based on Optical Fiber Sensor

Abstract

With the continuous development of my country’s economy, the demand for various high-tech products has also increased. Therefore, as an important detection tool for industrial production, optical fiber sensors have become one of the important tools for the development of the Internet of Things industry. Real-time monitoring and diagnosis of structural performance of main engineering structures, timely perception of structural damage, safety evaluation, structural performance changes and remaining life predictions Make maintenance decisions to improve, improve and ensure the operational efficiency of engineering structures and protect people’s lives and property. The structural health monitoring system collects data about the status of structural services in real time, uses specific damage recognition algorithms to determine the location and scope of damage, evaluates structural safety in a timely and effective manner, predicts structural performance changes, and provides early warning for emergencies. In recent years, structural health monitoring systems have become one of the hot topics in international academic research. In response to the needs of large-scale civil engineering health monitoring systems at home and abroad for monitoring methods, a method for structural health monitoring of high-piled wharves based on optical fiber sensor technology is studied. The structural health monitoring system of the high-piled wharf includes an intelligent monitoring system and a signal demodulation system.

Performance Evaluation System Based on Online Monitoring of Internet of Things

“…In order to achieve unity in different dimensions, this method normalizes the eigenvalues in each dimension to the same standard. is method can effectively identify the operating states of different electrical appliances, but its "voltage-current" trajectory value lacks intuitive representation [10]. Sciullo et al uses the clustering method to analyze the power data of the load and aggregates the electric loads with similar power characteristics into the same category, so as to realize the load identification.…”

“…e(u) = B(x)u e (7) where B(x) is called the strain function matrix, which is the derivative of N(x). In order to minimize the error of theoretical strain and actual strain, let the derivative function of Equation ( 5) with respect to u be zero, then Equation ( 8) can be obtained.…”

“…The monitoring of the structure is divided into static monitoring and dynamic monitoring according to the state of the measured structure. Monitoring of static structures has lower requirements on real-time performance, which can be measured directly using measuring equipment, and focuses more on the analysis of the measurement data [ 5 , 6 , 7 ]. However, the monitoring of dynamic structures requires higher real-time performance.…”

“…Researchers have also done many studies in the field of terminal health monitoring of Internet of Things (IoT) sensors. Guo et al (2021) [5] pointed out that in recent years, the health detection system of constructions had grown to be one of the research hotspots in the global scholarly community. In response to the demand for monitoring methods in the largescale civil engineering health inspection systems at the domestic and international levels, they researched a method for monitoring the health of high pile pier structures based on the technology of fiber optic sensors.…”
