Paper Abstract

At present there are exist comprehensive studies in the field of railway track condition monitoring systems and development of non-contact photonic systems based on digital CCD-cameras, high-speed board computers and powerful software. Creation of such systems allows to conduct preventive track maintenance work beforehand and to avoid the effects of vibration from wavy rail defects on a wheel set. As a result, the safety of running, durability of permanent way and rolling-stock are increased and the maintenance costs are reduced. The system developed consists of four special digital matrix CCD-cameras and four laser stripe illuminators. An electronic interface for linking the computer with the cameras, contour extraction models of the rail profile have been developed and the analysis of input- output ports has been carried out. According to the algorithms make a cut-off method and a tangent method have been compared.
