ADAPTIVE METHOD AND SYSTEM OF MONITORING SIGNALS FOR DETECTING ANOMALIES

摘要

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.
