Abstract
(DE) Die vorliegende Erfindung betrifft im Allgemeinen die Überwachung eines Rückzugsystems (100). Im Speziellen betrifft die vorliegende Erfindung eine Vorrichtung (10) zur Überwachung eines Rückzugsystems (100) mit mindestens einer Feder (12), ein solches Rückzugsystem (100) mit einer derartigen Vorrichtung (10), einen Roboter mit einer derartigen Vorrichtung (10) oder einem solchen Rückzugsystem (100) und ein Verfahren zur Überwachung eines solchen Rückzugsystems (100). Ein Ausführungsbeispiel der Vorrichtung (10() weist auf: mindestens einen mit der mindestens einen Feder (12) derart zusammengeschalteten Kondensator (14), dass die Zusammenschaltung aus der mindestens einen Feder (12) und dem mindestens einen Kondensator (14) einen Schwingkreis (16) bildet; eine Frequenzermittlungskomponente (20), die ausgebildet ist, Informationen über eine Frequenz des Schwingkreises (16) zu ermitteln; und eine Auswerteeinheit (30), die ausgebildet ist, aus den Informationen über die Frequenz des Schwingkreises (16) Informationen über eine Länge der mindestens einen Feder (12) abzuleiten.
(EN) The present invention relates to the monitoring of a retraction system (100) in general. In detail, the present invention relates to a device (10) for monitoring a retraction system (100) having at least one spring (12), to such a retraction system (100) having a device (10) of this kind, to a robot having a device (10) of this kind or such a retraction system (100), and to a method for monitoring such a retraction system (100). One embodiment of the device (10) has: at least one capacitor (14) connected to the at least one spring (12) in such a manner that the connection of the at least one spring (12) and the at least one capacitor (14) forms a tuned circuit (16); a frequency determination component (20), which is designed to determine information regarding a frequency of the tuned circuit (16); and an evaluation unit (30), which is designed to derive information regarding a length of the at least one spring (12) from the information regarding the frequency of the tuned circuit (16).
(FR) L’invention concerne de manière générale la surveillance d’un système de retour (100). En particulier, cette invention concerne un dispositif (10) pour surveiller un système de retour (100) comportant au moins un ressort (12), un tel système de retour (100) équipé d’un tel dispositif (10), un robot comportant un tel dispositif (10) ou un tel système de retour (100), et un procédé pour surveiller un tel système de retour (100). Un mode de réalisation du dispositif (10) comprend : au moins un condensateur (14) connecté avec le ou les ressort(s) (12), de manière que cette interconnexion comprenant le ou les ressort(s) (12) et le ou les condensateur(s) (14) forme un circuit oscillant (16) ; un composant de détermination de fréquence (20) conçu pour déterminer des informations sur une fréquence du circuit oscillant (16) ; et une unité d’évaluation (30) conçue pour déduire, à partir des informations sur la fréquence du circuit oscillant (16), des informations sur une longueur du ou des ressort(s) (12).
