Abstract

Selon la présente invention, dans un système de détection de dysfonctionnement de simulateur, une carte de surveillance multi-canal acquière des données de tension durant une période de mesure d'unité et transmet celles-ci à ordinateur. L'ordinateur calcule la valeur moyenne et l'écart-standard des données de tension acquises dans la période de mesure d'unité. S'il n'y a pas de fluctuations dans les données de tension acquises par répétition de multiples fois des périodes de mesure d'unité durant une étape d'acquisition de données initiale, ladite valeur de tension est utilisée en tant que tension de référence. S'il n'y a pas de fluctuations subséquentes dans la différence entre la tension de référence et la valeur de tension acquise par répétition de multiples fois des périodes de mesure d'unité, le système détermine qu'il n'y a pas de dysfonctionnement, et s'il y a des fluctuations subséquentes, le système réalise un traitement de dysfonctionnement. Le système est ainsi apte à acquérir et évaluer des données pour empêcher les dysfonctionnements à l'avance.
