Method for maintenance of railway infrastructure using digital railway model

FIELD: physics.

SUBSTANCE: method for maintenance of railway infrastructure using a digital railway model involves monitoring and diagnosing the condition of a railway section by monitoring and measuring the position of objects of its infrastructure and their geometric dimensions at different times using means of monitoring railway, overhead system, signalling, neutralising and blocking, synchronised on the linear coordinate of the railway and the geographical coordinate. Measurement data are processed based on a spatial three-dimensional coordinate presentation of the position and geometrical parameters of objects of the infrastructure. The obtained data are compared with data of the design spatial three-dimensional coordinate presentation of the position and geometrical parameters of the same objects of infrastructure presented in the digital model of the railway. Comparison results analysed with existing tolerance values and limitations to the position of objects and their geometry and comparison results are provided in order to bring the objects of the infrastructure to a position close to the design position, through communication channels in the railway operation service.

The invention relates to methods used for current maintenance of road and railway infrastructure, and can be used, in particular, when the control of the state road and track infrastructure and their compliance with the digital model of the path (the design part), and evaluation of such productions in conjunction with other rail infrastructure.

There is a method of measuring the geometry of the track and device for its implementation (EN 2256575, B61K 9/08, EV 35/00, G01B 11/00, G01S 5/00 from 20.07.2005), carried out through the implementation of high-precision measurement scheme using two kinematically connected measuring trucks, form of transport and mechanical part of the measuring system having a sensor of the traversed path and sensors levels of tilt of the cart relative to the horizon, at least one radiating brand (source of optical radiation), rigidly mounted on the first movement of the measuring trolley, providing clamping the flange of the wheel to the inner cylinder, the base of the rail, and opto-electronic receiving and analysis system, rigidly mounted on the second cart. When the second trolley is made with biaxial clamp the flanges of the respective wheel pairs to the inner surface of the head base of the rail, thereby forming the measuring base, identifying p is the position of the base of the rail at the points of tangency of the respective wheel pairs.

A disadvantage of the known technical solution is its narrow focus, lack of control and comparison with baseline (project) provision of road and infrastructure.

As the prototype accepted method of condition monitoring of railway track (EN 2226672, G01C 5/00, EV 35/00, 06.06.2002), which is done by gridding readings potenzmitteln devices to control the network using the on-Board computer installed on vipavadee car. The surveyed section of railway track binding to produce the coordinate system of the reference network. This is done using the database of the control system, which is injected computational coordinates, mark and stationing frames with measurements of distances to the nearest rail. On the basis of these data programmatically build a digital model of the route angles of rotation of the subject site the way, and then combine the coordinate system potenzmitteln device and the fixed network. Next get the exact continuous coordinate model, which is judged on the condition of the railway track for production in the project, or to an optimum position.

In the famous invention of improving the quality and performance of track maintenance is achieved by forming coordinate model based on the database of the control system and programs is but hardware potenzmitteln device, that narrows the possibilities for control of track maintenance.
