Problems solved by technology

[0004] 1. Because the sensors (such as fiber grating sensors) are expensive, they generally only monitor the settings of key parts, so that only the status of local points is monitored.
[0005] 2. There is no way to conduct health assessment and analysis on these parts because the data cannot be collected without sensor parts
[0006] 3. Evaluation and analysis methods are all separate and independent
It is only applicable to a specific engineering structure, and it lacks practical research and universality through long-term observation of its data for empirical analysis

Embodiment

[0041] A sensing data monitoring method based on finite element analysis, which is used to monitor and monitor building structures in real time. The finite element analysis in this method forms a class of constrained optimization based on dynamic equations, nominal models, and measurement data of the structure. problem to find the solution of the inverse mapping problem, and then discover, locate, and quantify structural damage by directly checking the difference between the updated matrix and the original matrix, specifically including: figure 1 Steps shown:

[0042] S101: The demodulator collects the sensing data of the physical engineering structure generated by the sensor;

[0043] S102: The demodulator sends the sensing data collected in step S101 to the upper computer;

[0044] S103: The upper computer sends the received sensing data to the data analysis center equipped with finite element analysis components;

[0045] S104: The data analysis center receives the sensin...

Abstract

The invention relates to a method and a device for monitoring sense data based on finite-element analysis. The method comprises the steps of: carrying out real-time monitoring on a physical engineering structure composed of a data analysis centre including a sensor, a demodulator, an upper computer and a user side and provided with a finite-element analysis component, storing the structure data collected by the sensor to the data analysis centre via the demodulator and the upper computer, reading structure data and transferring the finite-element analysis component to analyze by the data analysis centre when a user side transmits an inquiry request, transmitting the analysis result to the user side, and finishing inquiring. Compared with the prior art, the method and the device disclosed by the invention have the advantages of low cost, overall detection, high applicability, high reliability, convenience, fastness and the like.

Description

technical field [0001] The invention relates to a solid engineering structure monitoring system, in particular to a sensing data monitoring method and device based on finite element analysis. Background technique [0002] The health monitoring of engineering facilities has become a research hotspot in the world in recent years, and more and more large-scale engineering buildings in China have installed such health monitoring systems. Generally speaking, a health monitoring system is mainly composed of a data acquisition system, a data transmission storage system, and an evaluation and analysis system. It conducts real-time health and safety assessments of building structures to achieve the goal of safety warnings. [0003] The existing health monitoring systems generally have the following deficiencies and defects. [0004] 1. Because the sensors (such as fiber grating sensors) are expensive, they generally only monitor the settings of key parts, so that only the status of ...
