Determination of the reliability of rolling stock derailment control devices

Abstract

The article addresses the issue of determining the reliability of rolling stock derailment control devices.
To enhance reliability, a dual-channel actively redundant and recoverable system has been developed.
The analysis is based on reliability theory and Markov processes with discrete states. The state diagram
of the system and differential equations describing the probability of the system being in each of the three
states are presented. A structural redundancy scheme of the transmitting and receiving parts of the rolling
stock derailment control devices is also provided.
