  • control unit 48 and the data acquisition unit 46 can be combined into one unit, whereby the valve unit 43 is activated by the combined unit.

Abstract

La présente invention concerne un groupe hydraulique multifonctionnel servant à l'entraînement d'outils hydrauliques avec pour objectif de satisfaire à autant d'exigences que possible pour des applications les plus diverses du système. Cet objectif est réalisé d'une part par un concept de refroidissement et de filtration performant, d'autre part par la possibilité de mise en cascade modulaire du moteur et de l'électronique, ou encore par la possibilité de pouvoir monter des réservoirs supplémentaires quelconques par le biais de conduites d'aspiration ou de systèmes communicants. Pour satisfaire aux exigences de l'industrie en matière de gestion, d'accès et d'actualité des données, il est possible de commander et d'actualiser le groupe et d'échanger des données de manière bidirectionnelle par le biais d'un serveur central ou aussi par le biais d'un cloud. Les données de programme et/ou les données de processus et/ou les données de système du groupe hydraulique sont enregistrées au moyen d'un portail en ligne faisant office de service de cloud, puis analysées en vue de l'évaluation du processus et mises à la disposition d'un groupe de personnes autorisées pour téléchargement ou par le biais d'un navigateur Web. Un autre service de cloud informe automatiquement les utilisateurs et les clients lorsque des opérations de maintenance de l'équipement ou du système sont en cours ou nécessaires. En plus de cela, il est possible d'intégrer par le biais du cloud tous les accessoires utilisés du système afin d'inclure les intervalles d'entretien, ce qui permet d'obtenir un système global flexible et de garantir l'utilisation multifonctionnelle du groupe hydraulique dans le système composé.
