城市轨道交通全自动运行系统及安全需求

Fully Automatic Operation System and Its Safety Requirement of Urban Rail Transit

结合国内外全自动运行系统的运营研究资料,介绍国际轨道交通全自动运行系统发展状况,探讨全自动运行系统的功能结构。结合IEC62267与IEC62290等国际标准,论述全自动运行系统典型的系统功能与安全需求。以系统FAM与CAM模式转换为例,对运营场景进行分析研究,如实反映列车全自动驾驶系统真实的运营过程,在建模之前需对系统的功能进行梳理,实现需求到场景的追踪,以确保所建模型与功能需求的一致性,即此模型表达系统最终需要完成哪些功能,这些功能之间的关系如何以及系统完成这些功能需要与哪些外部参与者或系统实现交互。对全自动运行系统展开深入而全面的研究,对我国自主研发全自动运行系统提出参考建议,为全自动运行系统的安全运营保驾护航。

This paper discusses the development and function structure of automatic operation system for international rail transit by using the operation and research data of the system at home and abroad. It examines the typical automatic operation system and security requirements in line with IEC62267 and IEC62290 and other international standards. By taking the mode transfer of FAM and CAM system as an example, the operational scenarios are analyzed and the real operation process of the automatic driving system is reflected. The function of the system needs to be reviewed before modeling to meet the demand of the scene, which can guarantee the consistency between modeling and functional requirements. Specifically, the following aspects should be considered： what functions the model expression system should perform, what the relationship between these functions is and what external actors or systems are needed to interact with for these systems to complete their functions. In-depth and compre- hensive study of the whole automatic operation system is needed for research and for the development of independent system de- sign in China.
