THE USE OF COMPUTER TECHNOLOGY FOR AUTOMATION OF CAMERA PROCESSING OF RAILWAY INFRASTRUCTURE ELEMENTS IN THE PREPARATION OF TECHNICAL DOCUMENTATION

Purpose. When developing technical passports of industrial enterprises' sidings, as well as preparing large-scale schemes of main tracks on the runs and station tracks of mainline railway transport, the first stage involves geodetic surveying of the track development of the objects to be certified. On the one hand, the most accurate determination of the radii of curves of track sections is a rather laborious task, on the other hand, the presence of curves with variable radii complicates its solution and can lead to incorrect results. The aim of the study is to develop a method for determining the parameters of circular curves connecting adjacent straight sections of railroad tracks based on the results of a geodetic survey. The software implementation of the proposed method in the AutoCAD environment will automate the process of synthesizing curved track sections in drawings and accelerate the formation of track development plans for stations, main, connecting, and access tracks of industrial enterprises. Research methods. The methods of analytical geometry were used in the study. Results. At present, with the current level of development of computer and information technologies, it is advisable to use automated design systems to perform technical certification of railway tracks, which allow efficient processing of geodetic survey results and generate the necessary drawings. At the same time, when preparing plans for the track development of sidings, operations to determine the reliable parameters of curved track sections take considerable time. It was found that this takes an average of 35 minutes per 1 km of deployed track length. In this regard, we propose a method for selecting the best parameters of curved track sections based on the results of a geodetic survey, which is implemented as a software module for the AutoCAD computer-aided design system. Experiments with this module have shown its high efficiency, which has reduced the time for cameral processing of curved sections of railway tracks to 5 minutes per 1 km of their extended length and improved the quality of the results obtained. The scientific novelty is to improve the method for determining the reliable parameters of circular curves connecting adjacent straight sections of railway tracks based on the results of geodetic surveying using modern computer technologies. The practical significance lies in the software implementation of the proposed method in the AutoCAD environment, which allows automating the process of synthesizing curved track sections and accelerating the formation of track development plans for stations, main, connecting, and access tracks of industrial enterprises.
