介绍了北京轨道交通机场线综合信号控制系统体系结构及系统功能,并详细说明了各信号子系统的结构及系统功能。该系统采用先进的基于无线通信的无人驾驶移动闭塞列车自动控制系统。这种基于无线通信技术的自动控制系统将使机场轨道交通成为国内第一条完全无人驾驶的线路。机场线信号系统采用先进的列车控制系统,信号传送稳定可靠,列车间的安全防护距离更短,列车运营可以进一步缩短发车间隔,提高运营效率。 The architecture and system functions of Beijing Rail Transit Airport Line integrated signal control system are introduced. The structure and system functions of each signal subsystem are described in detail. The system uses advanced wireless communication-based unmanned mobile closed train automatic control system. This automatic control system based on wireless communication technology will make the airport rail transit the first complete driverless line in the country. Airport line signal system uses advanced train control system, the signal transmission is stable and reliable, the safety distance between trains is shorter, and train operation can further shorten the departure interval and improve operational efficiency.
