Technological communication on low-intensity railway sections

Abstract

The purpose of the study is to develop proposals for increasing the efficiency of the functioning of low-intensity railway sections (LIRS) by improving technological communication systems, taking into account the specifics of train traffic control on LIRS, as well as assessing the possibilities of using short-wave ionospheric radio communications and satellite communications in remote and extended LIRS. The study used methods for analyzing the characteristics of LIRS existing on Russian railways, methods for assessing radio communication channels based on Russian and international experience. As a result of the research, a classification of LIRS was proposed from the point of view of options for organizing technological radio communication systems on them, a unified scheme for constructing a radio communication system on LIRS was developed, and an algorithm was compiled for selecting the optimal option for the radio communication system in relation to each specific LIRS.
