| Abstract: | This paper analyzes reliability and safety of computer interlocking system, which can instruct interlocking system in rail application. Based on Markov model and taking into account of failure covering, this paper discusses in detail reliability and safety of TRM computer interlocking system. The quantitative expression for reliability and safety of the system is given. Its reliability, safety and practical application under normal circumstances is analyzed and conclusion of safe simulation is drawn. |
