Abstract

Un systeme de controle de detection des conditions dans une installation en fonctionnement comprend un groupe de detecteurs d'entrees pour detecter des conditions respectives, dont les sorties sont explorees en sequence par chacun des differents scanners. Les scanners stoppent des donnees representant temporairement les sorties des detecteurs. Chacun des processeurs de donnees fonctionne pour analyser les sorties de tous les scanners en sequence, et un reseau de "circuits de vote" connecte aux processeurs de donnees sort les donnees representant les conditions detectees en reponse a la concordance entre les articles de donnees produits par un nombre predetermines de processeurs de donnees. Le reseau de "circuits de vote" peut s'adapter pour repondre a la concordance entre les articles de donnees produits par un nombre different de processeurs de donnees dans le cas d'une defaillance de l'un ou plusieurs des processeurs de donnees. Un reseau de circuit de sorties connecte aux processeurs centraux commande des dispositifs d'alarme et/ou pour faire fonctionner des dispositifs de commande de traitement dans l'installation.
