Abstract

DANS LES DISPOSITIFS DE SURVEILLANCE CONNUS LES GRANDEURS A SURVEILLER SONT TRANSFORMEES EN SIGNAUX ELECTRIQUES QUI SONT CONVOYES PAR DES CONDUCTEURS ELECTRIQUES VERS UN CENTRE DE SURVEILLANCE. EN RAISON DU FAIT QUE LES INDICATEURS DE SIGNAL ELECTRIQUE NE PEUVENT ETRE UTILISES DANS DES ENDROITS PRESENTANT DES DANGERS D'EXPLOSION ET PEUVENT INDUIRE DANS LES CONDUCTEURS ELECTRIQUES DES SIGNAUX PARASITES, ON A DEJA PROPOSE DES DISPOSITIFS DE SURVEILLANCE A CONDUCTEURS OPTIQUES. SELON L'INVENTION, LES CAPTEURS POUR DISPOSITIF DE SURVEILLANCE OPTIQUE PERMETTENT DE SURVEILLER LA VARIATION CONTINUE ETOU LE DEPASSEMENT D'UNE VALEUR LIMITE DE GRANDEURS DE NATURE ELECTRIQUE, MECANIQUE OU THERMIQUE.
