Title (EN) METHOD AND SYSTEM FOR THE TIME SYNCHRONIZATION OF THE PHASE OF SIGNALS FROM RESPECTIVE MEASUREMENT DEVICES
(FR) MÉTHODE ET SYSTÈME DE SYNCHRONISATION TEMPORELLE DE PHASE DE SIGNAUX PROVENANT DE DISPOSITIFS DE MESURE RESPECTIFS
Abstract:
(EN) According to the invention, the time synchronization of the phase between measurement devices that do not share a single clock for the respective sampling of the signals thereof is carried out by the time tagging of signal samples in time blocks followed by an adjustment of the phase values of components of interest of the signals in the grouped time blocks, such that said values refer to time references which are common between the measuring devices. The tagging is carried out using a synchronization signal that is available for the measuring devices, and that is completed by means of counting values provided by a counter operated by a reference clock for each measurement device.
(FR) Une synchronisation temporelle de phase entre des dispositifs de mesure ne partageant pas une même horloge pour leur échantillonnage respectif des signaux est réalisée par un étiquetage temporel d'échantillons des signaux dans des blocs temporels suivi d'un ajustement des valeurs de phase de composantes d'intérêt des signaux dans les blocs temporels regroupés pour qu'elles se réfèrent à des références temporelles communes entre les dispositifs de mesure. L'étiquetage est réalisé avec un signal de synchronisation disponible aux dispositifs de mesure, complété par des valeurs de compte fournies par un compteur opéré par une horloge de référence pour chaque dispositif de mesure.
