Embodiment Construction

[0063] now by means of figure 1 6 through 6 describe various embodiments of the triangulation system 10 in detail. In this case, the same reference signs at least in principle always designate the same component parts.

[0064] Since this applies to all maglev rails, reference is made to maglev rail high-speed trains in this description here.

[0065] When monitoring the position of the motor winding in the stator laminations of the magnetic levitation track, possible vertical displacements of the stator cables 20 perpendicular to the stator laminations are checked in at least two different positions. The speed of the inspection vehicle and the measured speed in relation thereto shall be at least 100 km / h. The depth resolution is >30kHz.

Abstract

Disclosed is a method for the contactless measurement of an offset of the functional components of a travel path of a magnetic levitation railway driven by a linear motor with the help of at least one optical triangulation system (10) that can be moved along the travel path. Said method is characterized in that at least two triangulation sensors (12, 14) per measuring instrument for the functional components are moved along the travel path at a determined speed and alternately operate as a measurement sensor and as a reference sensor, i.e. using a radiation source in the ultraviolet, visible, or infrared spectral range, said triangulation sensors (12, 14) being fixedly mounted on a movable support (16) and being geometrically offset. In said method, the diffusely reflected light is absorbed at a specific angle of observation, and the position of the light incident on the measurement sensor is used for determining the offset, said process being carried out at a scanning rate that detects measurement points within a screen of < 1.5 mm.

Description

technical field [0001] The invention relates to a method and a device for non-contact measurement of offset of functional components of a magnetic levitation track driven by a linear motor by using at least one optical triangulation system traveling along a driving route. [0002] The invention therefore relates to a laser sensor based on the principle of optical triangulation, which detects and measures the position of the motor windings in the stator laminations, the relative position of the stator laminations in the path of the magnetic levitation track and / or the magnetic levitation without contact The vertical or horizontal offset of the functional parts of the train. Background technique [0003] The triangulation principle makes full use of the light-scattering effect of the light rays generated perpendicularly on the surface by receiving scattered reflected light by the photoelectric sensor element at a defined viewing angle. To determine the distance of the measuri...
