Abstract

Le domaine général de l'invention concerne les procédé de sécurisation aux pannes d'un système électronique comportant une pluralité d'équipements reliés entre eux par un réseau de communication asynchrone, ledit système comportant au moins un équipement dit « leader principal», ledit « leader principal » assurant l'organisation des tâches effectuées par les autres équipements. Dans le procédé selon l'invention, chaque équipement possède une liste prédéterminée de « leaders de remplacement », le « leader de remplacement » étant activé en cas de panne du « leader principal ». Le procédé selon l'invention s'applique tout particulièrement aux systèmes de visualisations des cockpits d'aéronef ; les équipements sont alors des calculateurs de bord et/ou des afficheurs ou « Display Unit », le ou les « leaders » ont pour tâches principales d'assurer le respect des règles de gestion des différentes configurations/reconfigurations d'affichage sur les afficheurs.The general field of the invention relates to methods for securing against failures of an electronic system comprising a plurality of items of equipment interconnected by an asynchronous communication network, said system comprising at least one item of equipment called “main leader”, said “ principal leader ”ensuring the organization of the tasks carried out by the other equipment. In the method according to the invention, each item of equipment has a predetermined list of “replacement leaders”, the “replacement leader” being activated in the event of failure of the “main leader”. The method according to the invention applies most particularly to systems for viewing aircraft cockpits; the items of equipment are then on-board computers and / or displays or "Display Units", the main task of the "leader" is to ensure compliance with the management rules for the various display configurations / reconfigurations on the displays.
