Abstract

L'invention concerne en général des systèmes et des procédés pour la commande d'instruments d'une machine de travail. Dans un mode de réalisation, un système de commande d'un instrument d'une machine de travail de tiers à commande hydraulique comprend un module de conversion reposant sur un microcontrôleur permettant de convertir des signaux de commande de l'instrument depuis leur format d'origine (PWM, par exemple) en un format de signal requis par l'instrument pour fonctionner correctement (numérique, par exemple). Un signal d'activation de flux hydraulique peut être simultanément généré et transmis à l'instrument de sorte que le flux hydraulique se produise uniquement lorsque les signaux de commande sont reçus et l'instrument est amené à être en mouvement ou activé d'une autre manière.
