摘要

Among the subsystems of railway, signalling system is the most important and key equipment of the automation system. Railway signalling system is responsible for directing and used to ensure the safety of train operation, to improve the efficiency of transport and other important tasks, thus the system has an irreplaceable role and high requirements of reliability. The graphical modeling ability of Stochastic Reward Net (SRN) for system reliability analysis can make the model intuitively described, at the same time, SRN can automatically generate a continuous time Markov chain, which has strong ability in mathematics. In this paper, firstly, the function and equipment structure of the railway signalling system is carried out, and then the reliability model of the system is established based on SRN to provide a reliable basis for the design and analysis of railway signalling system.
