  • timer relays relate to the ability to set an alarm, or other digital output, on a time-related condition.

A user can decide to program the server in step 86 or to activate, deactivate, or alter a process in step 88. Alternatively, a user can decide to schedule maintenance in step 90, to reset timer or counter relays in step 92, or to lock out unauthorized reconfiguration or resetting in step 94. A user can then resume monitoring data in step 82 and logs out, if necessary, in step 84 when finished.

Abstract

Cette invention a trait à des procédés et à des systèmes permettant à un utilisateur d'assurer une télémaintenance de dispositifs régulés. Dans un mode de réalisation, le système, qui comporte un transducteur intégré à un dispositif régulé, évalue des données émanant de ce dispositif. Un microprocesseur est couplé fonctionnellement à un transducteur et traite les données qu'il reçoit de celui-ci. Le système peut également être pourvu d'un serveur, connecté au microprocesseur et traitant des données émanant de celui-ci. Le serveur peut également être raccordé à un réseau pouvant faire transiter des données entre ledit serveur et un dispositif à distance commandé par l'utilisateur également raccordé au réseau. En exploitation, l'utilisateur peut contrôler les conditions de fonctionnement de dispositifs régulés via le serveur et peut intervenir, de manière sélective, pour agir sur ce ou ces dispositifs régulés. Plus particulièrement, un utilisateur peut analyser l'état d'exploitation d'un processus en utilisant un dispositif à distance commandé par l'utilisateur et, le cas échéant, en utilisant le même dispositif, modifier des paramètres du processus en envoyant une instruction au serveur. Le serveur exécute alors l'instruction grâce à un microprocesseur commandant le processus afin de conserver les conditions de fonctionnement du ou des dispositifs régulés.
