STATISTICAL AND RELIABILITY ANALYSIS OF FAILURES OF SIGNALLING DEVICES IN RAILWAY TRANSPORT

Emiliya Dimitrova, Vasil Dimitrov

High ments are set on the elements of signalling systems in railway transport in order to ensure traffic safety. Contemporary signalling systems perform multiple functions and are an integral part of remote monitoring and control systems in railway transport. The number of elements and new technologies in them is increasing - electronic, electrical, hydraulic, mechanical components, software, etc. interact synergistically. In the process of work, there is a constant interaction between them, and a possible failure even in one should not disrupt the proper functioning of the system as a whole. This determines the particular importance of the system reliability problem, and the increase in complexity makes the reliability analysis significantly more difficult.

In this paper, an approach is developed to analyse the failures of signalling devices in railway transport, which s statistical analysis of failures in subsystems and their elements and analysis of the reliability of individual components. Specific data are presented and the reliability indicators are determined.
