Abstract

A.DISPOSITIF AVEC UN EMETTEUR DE SIGNAL DE REFERENCE ET UN EMETTEUR AGISSANT LORS DE L'APPARITION DU PHENOMENE CARACTERISTIQUE AVEC UN GROUPE DE TRAITEMENT ET UN COMPARATEUR. B.CARACTERISE EN CE QUE, D'UNE FACON CONNUE EN SOI, LE GROUPE DE TRAITEMENT 10 EST RELIE A UN CIRCUIT LOGIQUE 6, 7, 8, 9, 11, 14 QUI COMBINE LES SIGNAUX DE SORTIE DU COMPARATEUR 4 QUI PRESENTE UNE VALEUR DE SEUIL QUE PEUVENT DEPASSER MEME DES SIGNAUX PARASITES, AVEC LES SIGNAUX D'UN CIRCUIT D'IDENTIFICATION 3, 6, LE GROUPE DE TRAITEMENT 10 ETANT COMMANDE PAR LES SIGNAUX DE SORTIE DU COMPARATEUR 4, L'INTERVALLE DE TEMPS QUI S'ECOULE ENTRE LE DERNIER DEPASSEMENT DE LA VALEUR DE SEUIL A L'ENTREE DUCOMPARATEUR 4 AVANT APPARITION DU SIGNAL DE SORTIE DU CIRCUIT D'IDENTIFICATION QUI REPOND A UN PHENOMENE CARACTERISTIQUE DE LA MACHINE, ET L'APPARITION DU SIGNAL ANGULAIRE DE REFERENCE, SERVANT AU GROUPE DE TRAITEMENT 10 POUR DEFINIR L'ANGLE DE ROTATION. C.DISPOSITIF APPLICABLE A UNE MACHINE A ARBRE ROTATIF.A. DEVICE WITH A REFERENCE SIGNAL TRANSMITTER AND A TRANSMITTER ACTING ON THE APPEARANCE OF THE CHARACTERISTIC PHENOMENON WITH A TREATMENT GROUP AND A COMPARATOR. B. CHARACTERIZED IN THAT, IN AN ITSELF KNOWN WAY, THE PROCESSING GROUP 10 IS CONNECTED TO A LOGIC CIRCUIT 6, 7, 8, 9, 11, 14 WHICH COMBINES THE OUTPUT SIGNALS OF COMPARATOR 4 WHICH PRESENTS A VALUE THRESHOLD THAT EVEN PARASITE SIGNALS CAN EXCEED, WITH THE SIGNALS OF AN IDENTIFICATION CIRCUIT 3, 6, PROCESSING GROUP 10 BEING CONTROLLED BY THE OUTPUT SIGNALS OF COMPARATOR 4, THE TIME INTERVAL BETWEEN THE LAST EXCEEDING OF THE THRESHOLD VALUE AT THE INPUT OF THE COMPARATOR 4 BEFORE APPEARANCE OF THE OUTPUT SIGNAL OF THE IDENTIFICATION CIRCUIT WHICH RESPONDS TO A CHARACTERISTIC PHENOMENON OF THE MACHINE, AND THE APPEARANCE OF THE REFERENCE ANGULAR SIGNAL, SERVING THE PROCESSING GROUP 10 TO DEFINE THE ROTATION ANGLE. C. DEVICE APPLICABLE TO A ROTATING SHAFT MACHINE.
