Abstract: Method for determining relative position indication of a position in a track. Measured values of a plurality of objects in track construction are determined by a measuring device, which measured values describe at least one property of an object of the plurality of objects. The measured values are compared with reference measured values or a reference measurement range, or a measurement pattern of the measured values is compared with a reference measurement pattern of a selected reference object to select a single object from the plurality of objects, determining a degree of similarity between the selected object and the reference object, which reference object is stored as an immovable reference object in the database, which degree of similarity is determined computationally and is indicated by a numerical value. The position in the track is indicated by a vectorial distance between an origin point arranged at the object and the position.

Abstract: A computer-implemented method for creating measurement data describing a railway network or a vehicle travelling on a track. Measurement values are detected by a sensor situated on the vehicle or on the track. A sensor processor in communication with the sensor requests a time value describing a time point and/or a position value describing a position and/or a measurement sample from a processor situated on the vehicle. The time value, the position value, and/or the measurement sample are transmitted from the processor to the sensor processor. The sensor processor assigns a measurement value to the time value, the position value, or the measurement sample, such that the time value, the position value, and/or the measurement sample describe a measurement time point or measurement position, and measurement data comprising the measurement value and the time value and/or the position value and/or the measurement sample are stored in a database.

Abstract: A method for determining an actual geometry of a track by a track inspection vehicle which is movable on the track, wherein reference points positioned in a lateral environment of the track are automatically recorded by a non-contacting recording system arranged on the track inspection vehicle and their respective actual distance from the track is determined. A three-dimensional trajectory of the track is recorded by an inertial measuring system arranged on the track inspection vehicle, wherein the trajectory is divided by a computing unit into trajectory sections each having a section starting point related to a first reference point and a section end point related to a second reference point, wherein a virtual longitudinal chord is defined for each trajectory section in relation to the assigned reference points, and wherein actual distances between the trajectory and the respectively defined longitudinal chord are calculated for each trajectory section.

Abstract: Method for creating a database for recording a railway line including objects, wherein first measurement values and second measurement values, which measurement values include measurement value attributes created by means of a sensor and/or by an input and which measurement values are created using an absolute coordinate reference system and/or relative first coordinate reference system, which measurement values describe a condition of the railway line or a vehicle traveling on the railway line, by performing coordinate transformation of the optionally relative coordinate reference system and the optionally absolute coordinate reference system into a unified coordinate reference system and by generating a unified measurement value set comprising the first measurement values and/or the second measurement values, are stored in the database, wherein, in generating the measurement value set, the measurement value attributes of the measurement values are stored in a database in a defined structure in the unified m

Abstract: The invention relates to a method of controlling a track maintenance machine, particularly a switch tamping- or universal tamping machine, which moves along a track and has working units, particularly a tamping unit and a lifting unit, which are adjustable relative to a machine frame, wherein position data of track objects, particularly sleepers, rails and optionally obstacles, are recorded by means of a sensor device in front of the working units in a working direction, and wherein operating positions of the working units are determined for a working operation at a track location. In this, prior to actuation of the working units, the determined operating positions of the working units are displayed by means of a display device, wherein, prior to carrying out the working operation, the operating positions of the working units can be changed by means of control elements.
