下一代地铁车辆全自动无人驾驶信号系统关键技术

结合国内外城市轨道交通的发展需求、自动无人驾驶列车运行控制系统的现状及技术发展战略,参考IEC 62279标准对列车运营自动化等级的分级定义,提出Bi TRACON型下一代地铁车辆全自动无人驾驶信号系统解决方案,该系统由综合自动化系统、轨旁控制器、车载控制器、计算机联锁和通信系统等组成,除具备传统的列车驾驶模式外,新增全自动列车自动驾驶模式和蠕动模式,无需工作人员值守,可以进行全自动列车运行控制;并且给出新增驾驶模式和既有驾驶模式之间的转换。Bi TRACON系统解决方案相比传统的轨道交通信号系统解决方案,在实现全过程的列车运行安全防护、灵活的运营组织、高效和节能、高度一体化和深度集成等方面有了显著提升。

Key Technologies for Unattended Train Operation Signaling System for New Generation Metro Vehicles

The paper proposes the BiTRACON system,the unattended train operation signaling system (UTO system) solution,for the new generation metro vehicles by referring to the requirements on mass rail transit and the current development trends of fully automatic unattended train control system as well as the classification of operation levels defined by IEC62279.The BiTR-ACON system is composed of TIAS,trackside controller,on-board controller,computer-based interlocking (CBI) and data communication system (DCS).Itimposes the full automatic driving mode (FAM) and creep automatic driving mode (CAM)in addition to the traditional train driving mode.In the FAM and CAM modes,the train is operated automatically and unattended.At the same time,the mode transition is described.Compared with the traditional train control system,the BiTRACON system solutionhas made great improvement,which can achieve safety protection for the whole operation time,flexible operation,high efficiency,saving energy,as well as deep and high integration.
