Abstract

L'INVENTION CONCERNE UN SYSTEME DE TRANSMISSION ET DE CENTRALISATION D'INFORMATIONS. CE SYSTEME COMPORTE UN POSTE CENTRAL EMETTEUR-RECEPTEUR DE TRAINS D'IMPULSIONS, UN NOMBRE QUELCONQUE DE POSTES SECONDAIRES, CONNECTES EN PARALLELE SUR UNE LIGNE UNIQUE RELIEE AU POSTE CENTRAL, CHACUN D'EUX COMPORTANT DES MOYENS POUR ENVOYER EN RETOUR AU POSTE CENTRAL AU MOINS UN SIGNAL LORSQUE LE NOMBRE D'IMPULSIONS QU'IL RECOIT EST EGAL A UN NOMBRE PREDETERMINE CARACTERISTIQUE DE CHAQUE POSTE SECONDAIRE ET DIFFERENT POUR CHACUN D'EUX, LEDIT SIGNAL AYANT DES CARACTERISTIQUES QUI DEPENDENT DE L'ETAT DU POSTE EN QUESTION, ET LE POSTE CENTRAL COMPORTE UN CIRCUIT RECEVANT ET ANALYSANT LESDITS SIGNAUX ET ALIMENTANT UN PANNEAU D'AFFICHAGE QUI INDIQUE L'ETAT CORRESPONDANT DE CHAQUE POSTE SECONDAIRE. UN TEL SYSTEME EST PARTICULIEREMENT ADAPTE A LA TRANSMISSION DES SIGNAUX D'ALARME.
