Reliability Analysis of Railway Signaling System Based Petri Net

摘要

Railway signaling system is essential equipment for high speed railway and passenger special line, and it play an important role to ensure safety and improve efficiency. Reliability analysis to railway signaling system is necessary and valuable. Railway signaling system is a complex and dynamic system. Petri net is a powerful mathematic tool to deal with concurrent and dynamic system. Taking hot standby system as an example, this paper uses petri net to analyze hot standby system and establish system modeling under the condition of using fiber-optic. Markov process and stochastic process are also used to compute the system reliability. The analysis process is accord to the actual working condition. It has important reference value to the other system design and analysis.
