Abstract

La présente invention se rapporte à un dispositif de commande de surveillance qui permet de collecter efficacement des informations exigées pour l'analyse ou autre de l'apparition d'une anomalie dans le dispositif de commande de surveillance lui-même, et de réduire le volume des informations de journal à mémoriser. Pour ce faire, le dispositif de commande de surveillance qui surveille l'état d'une usine est connecté à un moyen de commande servant à commander l'usine de manière à communiquer avec lui, et il peut émettre un signal de commande afin de donner au moyen de commande un ordre sur le contenu de la commande pour l'usine. Ledit dispositif de commande de surveillance comprend : un moyen d'obtention de journal qui permet d'obtenir des informations de journal relatives à l'état ou autre de ce dispositif de commande de surveillance ; un moyen de déclenchement de sonnerie d'alarme, qui sert à faire sonner des alarmes sonores quand une anomalie se rapportant à l'usine est détectée ; un moyen de détection d'opération qui est conçu pour détecter une opération d'arrêt de sonnerie d'alarmes sonores conformément au dispositif de commande de surveillance ; un moyen d'extraction de journal, qui est prévu pour extraire les informations de journal obtenues par le moyen d'obtention de journal dans un intervalle de temps prédéfini, le moment de la détection de l'opération d'arrêt de sonnerie servant de référence lorsque le moyen de détection d'opération détecte l'opération d'arrêt de sonnerie ; ainsi qu'un moyen de mémorisation d'informations de journal, qui est destiné à mémoriser les informations de journal extraites par le moyen d'extraction de journal.
