Title
(DE) SYSTEM UND VERFAHREN ZUR ÜBERWACHUNG VON SPANNUNGSZYKLEN
(EN) SYSTEM AND METHOD FOR MONITORING STRESS CYCLES
(FR) SYSTÈME ET PROCÉDÉ DESTINÉS À SURVEILLER DES CYCLES DE CONTRAINTE
Abstract
(EN) A system for monitoring stress cycles includes memory storing a base value and an inflection value of a stress cycle and one or more processors coupled to the memory. The processor(s) are configured to receive a series of stress values from a stress sensor. For each stress value in the series, the processor(s) are configured to perform operations including performing a first comparison between the stress value and a previous stress value in the series of stress values, detecting an inflection in the series of stress values based on the first comparison, updating the base value and the inflection value in response to detecting the inflection, performing a second comparison between the stress value and the base value, determining whether the stress cycle is complete based on the second comparison, and recording the stress cycle in response to determining that the stress cycle is complete.
(FR) L'invention concerne un système de surveillance de cycles de contrainte comprenant une mémoire stockant une valeur de base et une valeur d'inflexion d'un cycle de contrainte et un ou plusieurs processeurs couplés à la mémoire. Le(s) processeur(s) est/sont configuré(s) pour recevoir une série de valeurs de contrainte provenant d'un capteur de contrainte. Pour chaque valeur de contrainte de la série, le(s) processeur(s) est/sont configuré(s) pour réaliser des opérations comprenant l'exécution d'une première comparaison entre la valeur de contrainte et une valeur de contrainte précédente dans la série de valeurs de contrainte, la détection d'une inflexion dans la série de valeurs de contrainte sur la base de la première comparaison, la mise à jour de la valeur de base et de la valeur d'inflexion en réponse à la détection de l'inflexion, la réalisation d'une seconde comparaison entre la valeur de contrainte et la valeur de base, la détermination si le cycle de contrainte est complet sur la base de la seconde comparaison et l'enregistrement du cycle de contrainte en réponse à la détermination du fait que le cycle de contrainte est complet.
