Safety function design and application of CTCS on-board equipment in high-speed railway of China

Technical strength of high-speed railway of China such as standard construction, system design and equipment manufacturing has been rapidly enhanced through about ten years of high speed development. As the key part of safety guarantee of high speed railway operation in high speed railway train control system of China, on-board equipment has gradually reached world leading level along with the application and promotion of level CTCS-2 and level CTCS-3 train control system. Its core safety technology and characteristics have been adequately reflected in control type design, train safety positioning, movement authority generation and verification.
