Title
(EN) METHOD AND SYSTEM FOR DETECTING FASTENING STATE OF FASTENING STRUCTURE
(FR) PROCÉDÉ ET SYSTÈME DE DÉTECTION D'ÉTAT DE FIXATION DE STRUCTURE DE FIXATION
Abstract
(EN)
A method and system for detecting the fastening state of a fastening structure which fixes structural elements. At least a first vibration sensor is mounted on a first structural element for collecting vibration data of the first structural element. At least a second vibration sensor is mounted on a second structural element or on the fastening structure for collecting vibration data of the second structural element or the fastening structure. The fastening state of the fastening structure is determined using the vibration data collected. The method and system enable detection of the fastening state of a fastening structure with low power consumption and low cost.
(FR)
L'invention concerne un procédé et un système de détection de l'état de fixation d'une structure de fixation qui fixe des éléments structurels. Au moins un premier capteur de vibrations est monté sur un premier élément structurel pour collecter des données de vibration du premier élément structurel. Au moins un second capteur de vibrations est monté sur un second élément structurel ou sur la structure de fixation pour collecter des données de vibration du second élément structurel ou de la structure de fixation. L'état de fixation de la structure de fixation est déterminé à l'aide des données de vibration collectées. Le procédé et le système permettent la détection de l'état de fixation d'une structure de fixation avec une faible consommation d'énergie et un faible coût.
