AI Technical Summary

Technical Problem

Existing technologies cannot achieve real-time dynamic monitoring of submarine cable protection devices, lack the ability to collect multi-dimensional physical quantities such as strain, vibration, and attitude of key components in real time, and cannot perform fatigue damage accumulation analysis and life prediction, resulting in a lack of scientific basis for operation and maintenance decisions.

Method used

Employing a sensor subsystem, an acquisition and edge processing subsystem, a communication and cloud platform subsystem, and an analysis and early warning software subsystem, the system collects and analyzes strain, acceleration, and attitude data of submarine cable protection devices in real time. Through overall hydrodynamic and local finite element analysis, it identifies danger zones, performs resonance risk identification, strain hazard judgment, and fatigue damage accumulation assessment, and outputs graded early warnings.

Benefits of technology

It enables real-time dynamic monitoring of submarine cable protection devices, timely detection of potential problems, shortening the fault warning time to one or several days, improving the advance warning and accuracy of fault warning, reducing the risk of faults caused by information lag, and ensuring the safety margin and operation and maintenance efficiency of the submarine cable system.

Abstract

This invention belongs to the field of marine engineering and intelligent monitoring technology, specifically a real-time submarine cable protection system and its operating method. The real-time submarine cable protection system includes a sensor subsystem, a data acquisition and edge processing subsystem, a communication and cloud platform subsystem, and an analysis and early warning software subsystem. The sensor subsystem is used to collect data characterizing the status of the submarine cable protection device. The sensor subsystem is deployed on the submarine cable protection device within the danger zone determined by overall hydrodynamic analysis and local finite element analysis. Through the coordinated operation of the sensor subsystem, data acquisition and edge processing subsystem, communication and cloud platform subsystem, and analysis and early warning software subsystem, a closed loop of "sensing-processing-transmission-decision" is formed, realizing full-cycle dynamic monitoring and intelligent early warning of the wind turbine structural health status.
