Abstract: In order to make the signaling system of intelligent high-speed railway better meet the requirement of construction, operation and maintenance, and better coordinate with the technical system architecture of intelligent high-speed railway under the new situation, this paper analysed the current situation of intellectualization and integration of the main signaling systems of high-speed railway in China, and on this basis sorted out the revelent contents of signaling system among intelligent building, intelligent equipment and intelligent operation in Technical Architecture of Intelligent High-speed Railway 1.0. The paper discussed the development direction of intelligent and integrated technology of main signaling systems of high-speed railway in China, and put forward some developing suggestions for standards about the technical architecture with the purpose of providing references for the integration of signaling system and technical architecture of intelligent high-speed railway.
