Abstract

Cette invention concerne un système de commande (10) extrêmement flexible et modulaire qui peut être équipé ou remis à jour de manière à offrir un nombre ou une combinaison quelconques de caractéristiques telles que la sécurité, le théâtre/audio chez soi (54A), le CVC (54C), la gestion d'énergie (54F) et l'éclairage, chaque caractéristique étant associée à une unité remplissant une tâche distincte. Les unités remplissant une tâche peuvent être ajoutées ou retirées d'un ensemble principal d'unités tout en minimisant les répercussions sur ledit ensemble. L'ensemble principal d'unités comprend une unité de type base de données de commande (44) où des ensembles d'instructions sont stockés dans une base de données relationnelle en fonction d'un événement d'entrée/sortie, ainsi qu'une unité d'exécution des instructions (50) qui va envoyer les instructions vers les unités de tâche appropriées en vue de leur exécution. L'ensemble principal d'unité n'a pas besoin de comprendre l'événement d'entrée/sortie ni les instructions, et va plutôt envoyer ces instructions vers les unités de tâches concernées en vue de leur exécution. Ce système comporte une base de données de variables (48) qui comprend une base de données relationnelle des variables partagées entre les différentes unités de tâche, et qui renferme des objets tels que des affichages claviers. Les unités de tâche individuelles vont envoyer une requête à l'unité de la base de données de variables (48) concernant les valeurs de toutes les variables partagées, et recevoir automatiquement de l'unité de la base de données de variables (48) toute remise à jour des valeurs des variables partagées. Le logiciel (14) du système est stocké dans une ROM flash et peut être automatiquement remis à jour par l'intermédiaire d'une unité de tâche de téléchargement (52). Ce système peut également comporter une unité de tâche pour l'énergie (54F) qui va réguler la consommation électrique en fonction de toute modification du taux, et qui va établir une voie de communication avec une compagnie d'électricité.
