Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Bestimmung von Positionsverlagerungen in wenigstens zwei unterschiedlichen Raumrichtungen zwischen einem ersten Element und einem zweiten Element, welche relativ zueinander beweglich sind, mit wenigstens zwei berührungslos messenden Sensoren, welche in den wenigstens zwei unterschiedlichen Raumrichtungen zu wenigstens zwei mit dem zweiten Element fest verbundenen Maßverkörperungen beabstandet angeordnet sind, wobei Sensorflächen der wenigstens zwei Sensoren den wenigstens zwei Maßverkörperungen in der jeweiligen Raumrichtung gegenüberlie- gen und diese erfassen, wobei: - die wenigstens zwei Sensoren die wenigstens zwei Maßverkörperungen abtasten und in Wechselwirkung mit den wenigstens zwei Maßverkörperungen Ausgangssignale erzeugen, mit welchen in Kombination eine absolute Position des zweiten Elements bestimmt wird, welche mit einer linearen Bewegung in einer weiteren Raumrichtung oder mit einer Drehbewegung verbunden ist, und - wobei ferner mittels der Ausgangssignale der wenigstens zwei Sensoren Werte bestimmt werden, welche den Abstand zwischen dem jeweiligen Sensor und der entsprechenden Maßverkörperung des zweiten Elements in der zugehörigen Raumrichtung charakterisieren, welche in Abhängigkeit von der ermittelten absoluten Position des zweiten Elements korrigiert werden, und aus welchen die Positionsverlagerung des zweiten Elements relativ zu dem ersten Element in der jeweiligen Raumrichtung bestimmt wird.
(EN)
The invention relates to a method for determining shifts in position in at least two different spatial directions between a first element and a second element which are movable relative to each other, with at least two sensors which measure contactlessly and are spaced, in the at least two different spatial directions, from at least two standards which are fixed to the second element, sensor areas of the at least two sensors opposing the at least two standards in the respective spatial direction and sensing said standards, wherein: - the at least two sensors scan the at least two standards and generate, in interaction with the at least two standards, output signals with which in combination an absolute position of the second element is determined, said absolute position being associated with a linear movement in a further spatial direction or with a rotary movement, and - wherein the output signals of the at least two sensors are also used to determine values which characterise the distance between the respective sensor and the corresponding standard of the second element in the associated spatial direction, are corrected as a function of the determined absolute position of the second element, and from which the shift in position of the second element relative to the first element in the respective spatial direction is determined.

L'invention concerne un procédé de détermination de décalages en position dans au moins deux directions spatiales différentes entre des premier et second éléments mobiles l'un par rapport à l'autre, comprenant au moins deux capteurs qui mesurent sans contact et sont espacés, dans lesdites directions spatiales différentes, d'au moins deux étalons fixés au second élément, des zones de capteur desdits capteurs faisant face auxdits étalons dans la direction spatiale respective et détectant lesdits étalons, comprenant les étapes suivantes : - lesdits capteurs balayent lesdits étalons et génèrent, en interaction avec lesdits étalons, des signaux de sortie grâce auxquels, en combinaison, une position absolue du second élément est déterminée, ladite position absolue étant associée à un déplacement linéaire dans une autre direction spatiale ou à un mouvement rotatif. Les signaux de sortie desdits capteurs sont également utilisés pour déterminer des valeurs caractérisant la distance entre le capteur respectif et l'étalon correspondant du second élément dans la direction spatiale associée, sont corrigés en fonction de la position absolue déterminée du second élément, et à partir de ces derniers, le décalage en position du second élément par rapport au premier élément dans la direction spatiale respective est déterminé.
