Risk Analysis of Station Computer Interlocking in Railway Station

摘要

Railway signal system is an important infrastructure to ensure safe operation, loaded safe operation of railway, It has the characteristics of high scientific and technological content and complex security system. The safety of each signal subsystem determines the reliability and safety of the whole system, which takes computer interlocking equipment at ground station as an example, through a comprehensive safety risk analysis of the interlocking system, build a risk matrix based on risk frequency and risk severity, form a risk confidence interval. The constructed risk confidence interval provides a reference method for the safety assessment of the high-speed railway signal system.
