Системы радиосвязи высокоскоростного железнодорожного транспорта.

Abstract

Objective: To study the main approaches to organization of radio communication on high-speed railroad transport, to determine the requirements for functional capabilities and the structure of radio communication systems. Methods: The analysis of modern international and home practice in the sphere of radio telecommunication systems was applied for railway transport, on the basis of application strategy of interconnected indices’ complex, including reliability, availability, maintainability and safety (Reliability, Availability, Maintainability and Safety – RAMS) and cost (Life Cycle Cost – LCC) at all stages of transportation systems’ life cycle. Results: GSM-R standard was chosen as the basic one for organization of digital systems of engineering radio communication for high-speed mainlines. The choice was conditioned by the fact that the standard in question was developed for the purposes of railroad transport and is the basis for constructing European integrated railway radio enhanced network EIRENE (European Integrated Railway Radio Enhanced Network). Moreover, it was established that the most promising standard of radio communication for railway transport might be LTE (LTE-R) standard. Communication system capacity of the given standard, its applicability for the solution of the extensive range of railway radio communication tasks (including the task of providing customer radio communication) will make it possible to replace several different radio communication systems, solving specific functional tasks, by one which is more convenient and reliable. However, global and domestic experience of the standard in question application on railroad transport (including high-speed mainlines) has yet been insufficient, while the cost of LTE equipment is significantly higher compared to GSM-R standard. Practical importance: The requirements for functionality and structure of radio communication systems for high-speed networks were stated, including the requirements for digital systems of engineering radio communication (basic and reserved), the system of engineering on-line repair radio communication and digital wireless data communication system. Certain standards of radio communication allow for the realization of the given requirements.
