摘　　要：为了更好地实现城轨交通CBTC系统与城际铁路CTCS-2系统贯通运行,研究贯通运行的列车自动运行(ATO)技术方案,设计兼容双制式信号系统的ATO软件结构、制式转换逻辑和速度衔接方案。方案通过CBTC制式ATO软件与CTCS-2制式ATO软件前后台运行的方式,实现列车以AM模式在CBTC制式与CTCS-2制式间的无缝转换。在2种制式信号系统线路间设置制式转换区,列车在制式转换区内实现不停车转换。研究制定实验室仿真测试方案,搭建测试环境并执行制式转换功能测试,在测试中列车实现了CBTC制式ATO与CTCS-2制式ATO的双向平稳切换。测试数据分析结果表明,ATO在制式转换时的速度抖动在正常范围内,速度曲线平滑,证明了该技术方案的可行性。下一步将结合现场工程线路的技术条件,优化系统参数与软件结构,为系统功能的完善定型和后续工程化应用提供支撑。To enhance the interoperability of the CBTC system in urban rail transit with the CTCS-2 system in intercity railways,we explore an ATO technical scheme for interoperability.It includes designing dual-system-compatible ATO software architecture,system conversion logic,and speed transition plans.The scheme enables seamless conversion between the CBTC and CTCS-2 systems in AM mode through operating CBTC ATO software and CTCS-2 system ATO software in the foreground and background.A system conversion area is established between lines utilizing the two signaling systems,and the train thus realizes non-stop conversion in this area.We developed and implemented a laboratory simulation test plan,established the test environment,and carried out system conversion function testing.During testing,the train successfully achieves smooth bidirectional switching between CBTC ATO and CTCS-2 ATO systems.The test data analysis results indicate that the speed and jitter during system conversion in ATO mode fall within the normal range,and the speed curve remains smooth,confirming the feasibility of this technical scheme.Next,we will optimize the system parameters and software structure in conjunction with the technical conditions of the on-site project line to provide support for the refinement and finalization of the system functions and facilitate subsequent engineering applications.
