Title:
STRUCTURAL ANOMALY ASSESSMENT METHOD AND ANOMALY ASSESSMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/195536
Kind Code:
A1
Abstract:
Provided are an anomaly assessment method, and a system for the same, for assessing structural anomalies by inputting vibration data, measured in a structure, into a state assessment model. The system according to the present invention comprises: a vibration sensor for measuring vibration data; a database for storing big data including normal vibration data and anomalous vibration data; and a computation unit housing the state assessment model. The state assessment model is created on the basis of the big data by using machine learning, which includes artificial intelligence, and statistical methods. The computation unit further comprises an assessment device that inputs the measured vibration data into the state assessment model and assesses the present state of a structure on the basis of results computed from the state assessment model.
