城市轨道交通全自动运行系统(FAO)根据自动化等级分为GoA3有人职守的全自动运行和GoA4无人职守的全自动运行。针对全自动运行系统“中心强化管控、故障快速恢复”的功能需求特点,阐述全自动运行的核心专业——信号系统,从GoA2级向GoA4级过渡中在系统架构和功能上优化设计方案的重要性。以中心直接管控列车为出发点,重点从中央集中管控、设备安全可靠、故障快速恢复等方面,提出了采用双活中心、全电子联锁、集雷达与视频分析技术于一体的智能探测设备的优化建议,为提高全自动运行系统的可靠性、稳定性提供参考。

According to the grade of automation, the fully automatic operation (FAO) system of an urban rail transit can be divided into driverless train operation (GoA3) and unattended train operation (GoA4). FAO is a typical functional requirement about “center intensive control, and fast recovery of faults.” The signal system is the core of FAO. In view of the above- mentioned facts, this paper expounds on the importance of the system architecture and function of the optimized design scheme when the signal system transitions from level GoA2 to level GoA4. Beginning from the event of a center controlling train directly, this paper focuses on a center centralized control, equipment safety and reliability, and a fast recovery of faults. Optimization suggestions that provide a reference direction for improving the reliability and stability of FAO systems are raised with intelligent detection equipment that adopts a dual active center, fully electronic interlock, integrated radar, and video analysis technology.
