Abstract

La présente invention concerne un système d'automatisation de construction ainsi qu'un procédé d'automatisation de construction faisant appel à ce dernier et consistant à recevoir un message de demande en provenance d'un premier dispositif de construction qui communique au moyen d'un protocole BACnet, à vérifier la destination du message de demande et à réaliser un routage, puis à transmettre le message de demande à une passerelle en vue du traitement dudit message de demande. La passerelle convertit le message de demande en un protocole non BACnet et transmet le message de demande converti à un second dispositif de construction qui communique au moyen d'un protocole non BACnet. Par la suite, la passerelle reçoit un message de réponse en provenance du second dispositif de construction, convertit le message de réponse reçu en protocole BACnet, et transmet le message de réponse converti au premier dispositif de construction. La mise en oeuvre de ce procédé permet d'établir une compatibilité entre les deux dispositifs de construction qui utilisent des protocoles différents.
