高速铁路车载ATO工作模式

High Speed Railway Onboard ATO Working Mode

高速铁路列车自动驾驶(ATO)系统的标准性技术文件中,主要描述了列车超速防护(ATP)系统新增工作模式和系统使用操作,缺乏独立的ATO规范要素,如车载ATO工作模式、转换条件、功能边界等,容易导致标准条款在执行过程中一致性差、内容遗漏的问题,不利于系统互联互通及优化提升。为了完善标准体系中车载ATO功能规格,借鉴欧洲列车控制系统(ETCS)体系下ATO系统需求规范的描述方法和特点,研究和设计了满足中国列车控制系统(CTCS)要求的车载ATO工作模式,并以此为中心串联起状态、功能和流程等完整技术要求,最后从运营场景出发检验了设计的准确性和可行性,对产品研发、技术演进等方面具有重要参考意义。

The standard technical documents of high speed railway automatic train operation(ATO)system mainly describe new working mode and system operation of automatic train protection(ATP),with lack of independent ATO specification elements,such as working mode,conversion conditions and functional boundaries of onboard ATO,which may lead to poor consistency and content omission during implementation of standard clauses,and go against interconnection and system upgrade.In order to solve this problem,this paper studies the ATO system requirements under European Train Control System(ETCS)in terms of specification description methods and characteristics,designs the working mode of onboard ATO that meets the requirements of Chinese Train Control System(CTCS).Besides,the design connects all the technical requirements such as state,function and process,and proves the accuracy and feasibility of the design from operation scenario.The study is of great significance for product R&D and technological evolution.
