Research on Equipment Simplification and Cloud Construction of Urban Rail Transit Signal System

The rapid development of new technologies such as cloud computing, informatization and integrated circuit provides more direction for urban rail transit signal system. Starting from the signal system architecture, the simplification scheme of interlocking system, zone controller and on-board equipment system is proposed, and the cloud construction architecture of the central system is discussed. In order to achieve higher reliability, maintainability and expansibility, the scheme simplifies the signal system from the central equipment to the wayside equipment and then to the on-board equipment, providing reference for the development direction of the next generation signal system.
