摘要 为推进南京智慧城轨的建设发展,提高列车运行智能化程度,在南京地铁6号线建设时期提出设计变更,将既有机场线与宁溧线同步进行改造:提出ATO+方案,即在既有系统功能基础上增加ATO+驾驶模式,以实现部分自动功能;参照全自动运行模式,提出ATO+方案的8个运营场景。该方案涉及既有线信号系统、车辆系统、站台门系统的改造:信号系统改造车载硬件和软件,增加ATO+驾驶模式,轨旁信号系统升级软件兼容不同配置功能的列车混合运行;车辆系统改造与信号系统的接口电路,增加列车控制线,实现ATO+驾驶模式下的列车控制;站台门系统增加站台门与车门间防夹探测功能。具体实施兼顾改造前、后列车的混合运行,以保证改造过渡期不影响列车的正常运营。ATO+方案的实施,可以大大减少司机的干预,提升行车自动化程度和运营效率,为后续类似线路建设和既有线升级改造提供参考。 In order to promote the construction and development of Nanjing smart urban rail transit and improve the intelligent level of train operation,during the construction period of Nanjing Metro Line 6,the design change was proposed,and the existing Airport Line and Ningli Line were reconstructed simultane simultaneously.The ATO+scheme is put forward,that is,an ATO+driving mode is added on the basis of the existing system functions to realize some automatic functions.Referring to the operation scenario of the fully automatic operation line,8 operation scenarios of the ATO+scheme are proposed.The scheme involves the transformation of the existing signal system,vehicle system and platform door system:the transformation of the onboard hardware and software of the signal system,the addition of ATO+driving mode,and the upgrade of the software of the trackside signal system to be compatible with the mixed operation of trains with different configuration functions;the interface circuit between the vehicle system and the signal system is reformed to increase the train control line and realize the train control under ATO+driving mode;the platform door system is provided with anti-clamp detection function between platform door and train door.The mixed operation of trains before and after the transformation is implemented to ensure that the normal operation of trains is not affected during the transition period.The implementation of ATO+scheme can greatly reduce the intervention of drivers,improve the degree of driving automation and operational efficiency,and provide reference for the subsequent construction of similar lines and the upgrading of existing lines.
