Use cases of the complex

NDT vehicles NDT decryption

departments

Data visualization: ultrasonic, magnetic and eddy current channels

“Loupe” cursor, zooming-in one of recorded tracks “Distances measurement” cursor

Consolidated B-scan Different views of defectogram: ordinary B-scan, B-Scan with “By front”

mode, B-Scan with colorgraph mode, B-scan with gradient mode

Integrated view of data: ultrasonic, magnetic, eddy current, video, 3D

Integrated view of data from NDT devices

Automatic defect detecting in rail defectograms

Analysis of files from mobile and removable NDT vehicles. The complex can be adopted for any NDT hardware and for different NDT standards.

Ultrasonic channel data filtration

An algorithm for evaluating a signal dynamic threshold is developed for multi-bit defectoscopes. This threshold depends on a noise level and is individually calculated for every ultrasonic channel.

A multistage data filtration based on classical digital processing algorithms adopted for

defectograms is developed. This approach provides suppressing noise and leaving useful signals.

Calculation of flaw danger degree

4 categories of flaw danger degree are appointed in the UIC-725 standard: 0, I, II, III. The complex provides automatic flaw danger degree calculation.

Flaw danger degree in the flaw panel based on the European standard UIC 725

Automatic analysis of additional characteristics

The panel with acoustic contact existence results The panel with ground echo signal loss results

The panel with joint detection results The panel with violation of the control technology results

Automatic analysis result comparison of the same place from several passages

This feature allows to compare defect

markers automatically detected on two or

more passages of the same place in the

rail. To compare the markers, it is

necessary to decode all the opened

passages and apply this feature. After that,

the panel with the coinsident markers will

appear.

Railway object information

Database editor for railway infrastructure

GIS - application

Data visualization on the map: the current position and the route of a NDT vehicle, detected railway defects, joints, GPS-tracks, the results of the control stop, etc.

Reporting system and automatic reports generation

The reporting system provides collecting all the railway information including the results of field inspections and generating all kinds of reports

- Inspection result report 1 - Inspection result report 2 - The report of bolted joints with non-recorded bolt bores - A list of segments with a ground echo signal loss - The report of non-inspected rail segments - The consolidated passage report
