Title (EN) ADAPTIVE METHOD AND SYSTEM OF MONITORING SIGNALS FOR DETECTING ANOMALIES
(FR) PROCÉDÉ ET SYSTÈME ADAPTATIF DE CONTRÔLE DE SIGNAUX POUR DÉTECTER DES ANOMALIES
Abstract: front page image
(EN)There is described a method for detecting anomalies in a set of signals that normally exhibit analogous behaviour. The method comprises: acquiring a set of signals from at least one measurement source; designating a reference signal Sref from the acquired set of signals; computing a deviation Devi between the reference signal Sref at a reference point in time tref (Sref(tref)) and at least one of the acquired signals Si over time; and generating a deviation alarm trigger when the deviation meets a given deviation criteria.
(FR)L'invention porte sur un procédé de détection d'anomalies dans un ensemble de signaux qui présentent normalement un comportement analogue. Le procédé consiste ä: acquérir un ensemble de signaux provenant d'au moins une source de mesure; désigner un signal de référence Sref à partir de l'ensemble acquis de signaux; calculer un écart Devi entre le signal de référence Sref au niveau d'un point de référence dans le temps tref (Sref(tref)) et au moins un des signaux acquis Si dans le temps, et générer un déclencheur d'alarme d'écart lorsque l'écart correspond à un critère d'écart donné.
