Title (EN) DEVICE FOR MONITORING ABNORMALITY IN SAMPLED SIGNALS
(FR) DISPOSITIF DE CONTROLE D"ANOMALIES DANS DES SIGNAUX ECHANTILLONES
Abstract: front page image
(EN)Device for detecting an abnormal condition in an apparatus on the basis of sampled signals obtained by sampling a periodic AC signal at a predetermined time interval The device includes a memory circuit (3) for storing n (n3) consecutive items of data obtained by digitally converting a periodic AC signal which has been sampled at predetermined time intervals, and a coincidence-detection circuit (4) for checking whether the stored content of the memory circuit is the same for each sampling, thereby to detect an abnormality in the sampled signals. The device is therefore suitable for monitoring malfunctions in the analogue data-input section of a digital processing unit.
(FR)Dispositif de detection d"une condition anormale dans un appareil se basant sur des signaux echantillonnes obtenus par echantillonage d"un signal periodique a courant alternatif a un intervalle de temps predetermine. Le dispositif comprend un circuit memoire (3) pour stocker n(n (Alpha) 3) articles consecutifs de donnees obtenues par conversion digitale d"un signal periodique a courant alternatif qui a ete echantillone a des intervalles de temps predetermines, et un circuit de coincidence-detection (4) pour verifier si le contenu stocke du circuit memoire est le meme pour chaque echantillonnage, de maniere a detecter une anomalie dans les signaux echantillonnes. Le dispositif est approprie pour controler les defauts de fonctionnement dans la section d"entree des donnees analogique d"une unite de traitement digital.
