Main benefits of MDC
High reliability of detecting rail’s defects:
-
24 channel ultrasonic scheme with four methods of ultrasonic inspection and patented inspection modes;
-
defects detection under the surface of the railhead by magnetic channel at temperature - 50ºC;
-
complex analysis of diagnostic information by acoustic and magnetic defectogram and video frames;
-
localization sectors of the track with corrosion damage of the rail foot;
-
contactless (magnetic) alignment of inspection system concerning to rail longitudinal axis.
Video reporting of rail’s elements:
-
different types of cameras for video documentation of rails condition, rail braces, bolted and welded joints and elements of track switches (speed of up to 65 kmh);
-
high quality of image due to economical flash lighting of camera and system of protective shutters at any climatic conditions;
-
program regulation of brightness additional lighting, also directions of review and optical zoom of operated video cameras;
-
video information transmission for future monitoring of rail track condition and infrastructure facilities.
Automation of handling diagnostic information:
-
output of information processing results of the track geometry control system with determination of deviation from the standards;
-
synchronization of the inspection signals with video information;
-
automatic defining bolted, isolated and welded joints, track switches with protocol generation;
-
automatic determination gap’s value of bolted joint;
-
synchronic analysis of current and previous inspection (monitoring of the developing flaws and rail’s condition);
-
automatic search of the track’s sections with absence acoustic contact;
-
recoding of inspection protocol, telegrams for the purpose of changing of high defective rails and subsequent transmission it via GPRS from the car.
Minimization of maintains expanses:
-
contactless sensors for measurement geometry of rail track geometry;
-
contactless (magnetic) alignment of the inspection system concerning to rail longitudinal axis;
-
electro drive for moving up/down measure;
-
pneumatic drive of moving up/down of inspection system;
-
displaying an information about consumption and temperature of couplant;
-
two cameras for looking after the inspection system during testing;
-
comfortable living and working conditions of the crew.
