Sensing data monitoring method and device based on finite element analysis

Abstract

The present invention relates to a sensory data monitoring method and device based on finite element analysis. The method is composed of a sensor, a demodulator, a host computer, a user terminal, and a data analysis center equipped with finite element analysis components. The structure is monitored in real time, and the structural data collected by the sensor is saved to the data analysis center through the demodulator and the host computer. When the client sends a query request, the data analysis center reads the structural data and calls the finite element analysis component for analysis, and The analysis results are sent to the client to complete the query. Compared with the prior art, the invention has the advantages of low cost, comprehensive detection, high applicability, high reliability, convenience and quickness, 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 ...

AI Technical Summary

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
