Title
(EN) CLASSIFYING VIBRATIONS
(FR) CLASSIFICATION DE VIBRATIONS
Abstract
(EN)
It is provided a method for classifying vibrations detected in a structure of a building. The method is performed in a vibration classifier and comprising the steps of: determining a measurement period of a vibration signal; splitting the measurement period in a plurality of sequential sub-periods; calculating, for each one of the sub-periods, a variation indicator of at least one component of the vibration signal; and classifying a source of the vibration signal based on the variation indicators.
(FR)
L'invention concerne un procédé de classification de vibrations détectées dans une structure d'un bâtiment. Le procédé est mis en œuvre dans un classificateur de vibrations et comprend les étapes suivantes consistant : à déterminer une période de mesure d'un signal de vibration ; à diviser la période de mesure en une pluralité de sous-périodes séquentielles ; à calculer, pour chacune des sous-périodes, un indicateur de variation d'au moins une composante du signal de vibration ; et à classifier une source du signal de vibration sur la base des indicateurs de variation.
