A redundancy system switching control system includes two packages and logic circuits. The two packages are alternately switched as an operating system package and a standby system package. The logic circuits are arranged on the two packages, respectively, and each of the logic circuits outputs selection information/non-selection information to a remote package using self-package alarm information, self-package forcible switching information, remote-package alarm information, and selection information/non-selection information as four inputs. Each of the logic circuits, when a self-package serves as the operating system package, outputs selection information to the remote package by receiving any one of non-selection information from the remote package and the self-package alarm information when the self-package does not receive the remote-package alarm information. Each of the logic circuits, when the self-package serves as the standby system package, outputs non-selection information to the remote package by receiving any one of selection information from the remote package and the self-package forcible switching information.

Système de commande de commutation de systèmes redondants. Comprend deux ensembles systèmes et des circuits logiques. Les deux ensembles systèmes sont commutés en alternance en tant qu'ensemble de système principal et ensemble de système de relève. Les circuits logiques sont adaptés aux deux ensembles, respectivement, et chacun desdits circuits logiques transmet une information de sélection/non-sélection à un ensemble éloigné en utilisant les quatre entrées suivantes : information d'alarme de l'ensemble autonome, information de commutation forcée de l'ensemble autonome, information d'alarme de l'ensemble éloigné, et information de sélection/ non-sélection. Chacun des circuits logiques, lorsque l'ensemble autonome sert d'ensemble de système principal, transmet une information de sélection à l'ensemble éloigné en recevant toute information de non-sélection de l'ensemble éloigné et une information d'alarme de l'ensemble autonome lorsque ce dernier ne reçoit pas d'information d'alarme de l'ensemble éloigné. Chacun des circuits logiques, lorsque l'ensemble autonome sert d'ensemble de système de relève, transmet une information de non-sélection à l'ensemble éloigné en recevant toute information de sélection de l'ensemble éloigné et une information de commutation forcée de l'ensemble autonome.
