Based on the constitutive safety technology architecture of high-speed train through "Research and design - Manufacturing - Maintenance guarantee" the whole life cycle, constitutive safety typical techniques of the design and development process were introduced in detail, especially fire prevention, collision and anti-icing technology which concerned by key projects of national advanced rail transit. Combining high-speed train product technology and operation demand outlook, the future development direction of the constitutive safety technology of high-speed train was prospected.
