METHOD OF DETERMINING PARAMETERS OF TRACK GEOMETRY AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC B61K9/08 E01B35/00 

FIELD: transportation.

SUBSTANCE: invention relates to the field of railway automation and telemechanics for continuous recording of the spatial position of track in path diagnostics, design and survey and other types of works. To implement the method of determining parameters of track geometry, a system consisting of a track measuring bogie (1) and a photogrammetric coordinate measuring device (2) is used. Positioning device (1) moves on two wheel pairs (8) connected by longitudinal support frame (12). On the bogie three sighting targets (7, 11) are installed. One has the shape of cylinder and is located vertically upwards on support frame closer to rear wheel pair. Other two are shaped to a ball and are located at the ends of the front axle of the wheel pair. Centre of axis lies on one straight line with their centres. Plate of the laser radiation reflector (9) with a sighting mark is placed above the centre of the said axis. With its help photogrammetric coordinate-measuring device (2) tracks movement of measuring device (1) and performs continuous registration of coordinates of sighting targets (11) installed on axle of wheel pair above left and right threads of track, respectively. These coordinates are used to define parameters of rail track geometry.

EFFECT: result is automation of the process, higher accuracy characteristics when determining parameters of track geometry.
