Geo-information technologies in the rail transport intellectualization

Abstract

Geo-information technologies in the intellectualization of railway transport can be used to monitor the state of the railway track, identify dangerous changes in sections of the railway track, monitor the congestion of the railway network and predict its development, as well as ensure the safety of rail transport. The article presents the possibility of using geo-information technologies for monitoring rail vehicles on the route and monitoring the geometry of the track, which are integrated into the information management system. It was found that the use of geo-information technologies in the intellectualization of railway transport made it possible to confirm the dynamic models of the destructive impact of the train on the track and the most negative parameters of the train and the mode of movement, which must be taken into account when the movement of intelligent railway transport is controlled. The work identifies three main factors that affect the traffic safety of intelligent railway transport and reduce the destructive effect on the track. It is proposed to use the means of global control - space, aviation and ground means of remote sensing with high-precision referencing by GLONASS/GPS equipment for monitoring long sections of the railway track. The concept of integration into a single technological complex of aerospace and traditional technologies for monitoring deformations of long sections of the track and adjacent territories for the prevention and prevention of emergencies has been developed. For the automated recognition of railway tracks on images, a technique has been developed based on the detection of rectilinear objects using the Hawk transformation. The changes in the track geometry under the train rolling stock load have been researched. The key factors have been identified, which been ap-plied will reduce the train's negative impact on the track and negative natural and anthropogenic phenomena in the track adjacent areas. The continuous process of integrating methods, monitoring tools and derailment prevention into a single information control system is shown.
