METHOD FOR AUTOMATIC MONITORING OF STATE OF RAIL BARS OF CONTINUOUS WELDED RAIL TRACK AND SYSTEM THEREFOR Russian patent published in 2017 - IPC B61K9/08 E01B35/12 

FIELD: physics, measurement technology.

SUBSTANCE: invention relates to inspection technology and can be used to inspect railway tracks. The method for automatic monitoring of the state of rail bars of a continuous welded rail track includes placing and fixing at a given point of a rail track a set of markers, detecting the position of the markers with a sensor installed on a vehicle moving on the rail track, sending the detection results to a pre-processing device, processing the obtained results in the pre-processing device and sending the pre-processed information to a server device for final processing, analysis and storage. The set comprises at least three magnetic markers. One of the magnetic markers of the set is placed and fixed directly on a beacon sleeper and the rest on two sides thereof at a distance of at least 0.8 m at the rail base. Detection is carried out using a magnetic field sensor, and detection results are processed using software which enables to determine mutual arrangement of the markers in the set. Also disclosed is a system for implementing said method for automatic monitoring of the state of rail bars of a continuous welded rail track.

EFFECT: providing automatic high-precision monitoring of longitudinal-transverse deformations of rail bars on a section of a main railway line, independent of weather conditions.
