SYSTEM AND METHOD OF MONITORING RAILWAY TRACK Russian patent published in 2010 - IPC G01C3/08 B61K9/08 

FIELD: physics.

SUBSTANCE: method of monitoring a railway track involves steps on which: a line is illuminated from one end of the railway track to another; part of the light reflected from the track is received; a set of images are generated; the set of images is analysed; the set of images is compiled; corresponding geographical locations of the images are recorded; physical characteristics of a part of the railway track is displayed. A system which realises the method of monitoring a railway track and which is installed on a vehicle includes: at least one light source which is a laser lying next to the railway track for projecting a light beam from one end of the track to the other, one optical receiver lying next to the railway track. The optical receiver has a digital camera, one processor for analysing the set of images and determining geographical location of the set of images. The processor can compile the set of images and record the corresponding geographical location of the set of images.

EFFECT: simplification of the procedure of monitoring the state of a railway track.
