城市轨道交通信号系统设备精简化及云架构探究

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

云计算、信息化、集成电路等新技术的高速发展,为城市轨道交通信号系统提供了更多的发展方向。从信号系统架构出发,提出了联锁系统、区域控制器和车载设备系统的精简化方案,探讨了中心系统云平台架构,将信号系统从中心设备到轨旁设备再到车载设备进行简化,以期达到更高的可靠性、可维护性和可拓展性,为下一代信号系统发展方向提供参考和借鉴。

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.
