Abstract

Interface (fig. 2) entre la clé (2) et le verrou (3) d'un système de serrure électronique (1) et une installation de commande et de contrôle à distance (20), telle qu'un poste central de sécurité, dans un bâtiment de bureau, un hôtel ou tout autre établissement de ce type à plusieurs accès. Cette interface est également conçue pour assurer la commande autonome d'un ou plusieurs dispositifs auxiliaires d'entrée/sortie tels qu'une caméra de surveillance, une alarme incendie ou autre dispositif de ce type. Pour communiquer avec l'unité de verrouillage, l'interface comporte une première voie de communication (11) qui est couplée au contrôleur interne de l'unité de verrouillage (3). De même, une deuxième voie de communication (21) assure la communication avec le processeur de commande au niveau du poste central de contrôle (20). Un processeur de commande d'interface est branché à chacune de deux voies de communication et fonctionne de façon à échanger des messages avec un contrôleur contenu dans l'unité de verrouillage (3) et un processeur de commande dans le site éloigné (20).
