Title (EN) SYSTEM FOR MONITORING PIPE-RETAINING STRUCTURES
(FR) SYSTÈME DE SURVEILLANCE DE STRUCTURES DE RETENUE DE TUBES
Abstract:
(EN) Methods for monitoring the positions of latch members in a fingerboard structure through use of wireless sensors include using wireless sensor data to determine the angular position of a given latch member, in real-time. If the angular position of the latch member deviates from an expected position by more than a threshold value, this may indicate a possible malfunction of the latch member, and a pipe moving operation may be cancelled. The wireless sensors may also measure rates of movement of a latch member toward the open and closed positions. The rates of movement may be used to estimate the health and useable life expectancy of the latch member. Additionally, if the movement of the latch does not fall within threshold minimum and maximum values, or if the movement of a latch does not correspond to a command, pipe moving operations associated with the latch member may be canceled.
(FR) Cette invention concerne des procédés de surveillance des positions d'éléments de verrouillage dans une structure de râtelier à tiges par l'utilisation de capteurs sans fil, comprenant l'utilisation de données de capteur sans fil pour déterminer la position angulaire d'un élément de verrouillage donné, en temps réel. Si la position angulaire de l'élément de verrouillage s'écarte d'une position attendue de plus d'une valeur de seuil, cela peut indiquer un éventuel dysfonctionnement de l'élément de verrouillage, et une opération de déplacement de tube peut être annulée. Les capteurs sans fil peuvent également mesurer des vitesses de déplacement d'un élément de verrouillage vers les positions ouverte et fermée. Les vitesses de déplacement peuvent être utilisées pour estimer la santé et la durée de vie utile de l'élément de verrouillage. De plus, si le déplacement du verrou n'est pas à l'intérieur de valeurs seuil minimale et maximale, ou si le déplacement d'un verrou ne correspond pas à une commande, des opérations de déplacement de tube associées à l'élément de verrouillage peuvent être annulées.
