Abstract

L'INVENTION CONCERNE UN ENREGISTREUR DE SIGNAUX SUR PERTURBATION. UN CIRCUIT D'ENTREE 11 A 14 RECOIT UNE SERIE DE SIGNAUX A SURVEILLER ET LES ECHANTILLONNE POUR FOURNIR A CHAQUE FOIS UN MOT NUMERIQUE A UN CIRCUIT DE PRE-MEMOIRE 31, 32, QUI CONSERVE EN PERMANENCE LES N MOTS NUMERIQUES LES PLUS RECENTS. EN PRESENCE D'UNE PERTURBATION, UNE UNITE CENTRALE 40 EXCITE UN CIRCUIT DE MEMOIRE PRINCIPAL 51 ET 42 POUR QU'IL ENREGISTRE LES N MOTS NUMERIQUES LES PLUS RECENTS AU MOMENT DE LA PERTURBATION, AINSI QUE LES MOTS NUMERIQUES SUIVANTS PENDANT ET APRES LA PERTURBATION. LE CONTENU DE LA MEMOIRE PRINCIPALE 51 EST PAR AILLEURS TRANSFERE A CADENCE LENTE DANS UN CIRCUIT DE SORTIE 61 A 64, QUI RETRANSFORME LES SIGNAUX SOUS FORME ANALOGIQUE ET LES APPLIQUE A UN ENREGISTREUR GRAPHIQUE 70. APPLICATION NOTAMMENT A LA SURVEILLANCE DES RESEAUX ELECTRIQUES.
