Research and Prospect of Intelligent Control Technology for Virtually Coupled Train Formation

Train operation control method has gone through the development of fixed block, quasimoving block and moving block. With rapid development of a new generation of information technology, such as vehicle networking and swarm intelligence, advanced train operation control technology with more efficient becomes hotspots. Orienting the next generation of train operation control system, this paper researches on a kind of collaborative intelligent control technology of train based on virtual coupling. This paper proposes the method to control the operation of a virtual coupled train group using multi-agent system(MAS), and describes its control rules and built train group in order to stabilize control model aiming for collaborative operation. On this basis, train control and dispatching system framework are designed based on virtual coupling. Using simulation technology to verify the method can reduce train operation intervals and improve operation control efficiency. Finally, this paper analyzes and summarizes the research and development direction of train operation control technology based on swarm intelligence.
