Estimating Technology of Safety Integrity Level of Safety-Related Systems in High-speed Train

Based on the concept and evaluation methods of safety-related systems and safety integrity levels specified in the relevant international standards, this paper is described Estimating Technology of Safety Integrity Level of high-speed train in detail. Additionally, select a critical electrical system of high-speed train as the analysis object, and then identification and calculation of its SIL grade. This paper provides a basis for SIL level evaluation of High-speed Train.
