Definitions

  • the present invention relates generally to systems and methods for controlling and monitoring a variety of systems, using modular object-oriented control software which is operated in a local controller associated with the controlled system, and centrally controlled, monitored, and updated using a communications network such as the Internet.

Abstract

L'invention concerne une méthodologie de système de commande utilisant un logiciel orienté objet pour intégrer de multiples systèmes de commande afin d'obtenir un modèle objet commun. Des techniques orientées objet sont utilisées pour construire des applications Java réparties dans un environnement de système ouvert à vendeurs multiples, s'utilisant dans des systèmes de commande et de surveillance de taille et de configuration variées. Le système comporte un client (101) de navigateur (utilisant un navigateur reconnaissant Java) et un client de serveur. La présente invention comporte des postes multiples : un serveur (110) web BAS, un processeur (111) de réseau (NP) et un organe (112) de commande de champ (FC). Le NP et le FC sont de préférence des machines virtuelles Java installées dans un environnement modulaire Java enfichable. Des informations sont rassemblées pour former un modèle objet commun et sont mises à disposition sur tout le système. Un langage de programmation personnalisé à base de Java est prévu pour produire des objets, l'accès aux objets étant commandé par l'intermédiaire d'un protocole de sécurité multiniveaux. Le flux de données est dirigé par un gestionnaire de synchronisation d'informations en temps réel.
