摘要:
［目的］为了满足市域铁路CBTC(基于通信的列车控制)信号系统与铁路CTCS-2(中国列车控制系统2级)信号系统互联互通的运行需求，特开展本研究。［方法］在现有CBTC和CTCS-2信号系统的架构基础上，提出该两种信号系统的融合方案。对两种融合方案在成本投入、影响范围、改造难度和适用范围这4个方面进行比较，最终选用车载设备同时满足两种不同信号制式地面设备的融合方案。其中，地面设备秉持“CTCS设备尽量少变，增加或修改CBTC设备”的设计原则，车载设备秉持“ATP（列车自动保护）核心设备独立，外围部件尽量共用”的设计原则；在保证系统运营效率、满足CTCS-2相关标准的前提下，提出“列车从CTCS-2线路转换至CBTC线路的转换方案”和“列车从CBTC线路转换至CTCS-2线路的转换方案”，以实现市域铁路CBTC与CTCS-2双向互联互通贯通运行。［结果及结论］研究结果表明，该选用方案的实现能够提升市域铁路运输效率，优化运输组织与管理，完善轨道交通网络化功能，促进中心城市与周边城市的协调发展。
Abstracts:
［Objective］ The research is specially carried out aiming to meet the operational requirements for interoperability between city railway CBTC (communication-based train control) and railway CTCS-2 (China train control system level 2) signaling systems. ［Method］ Based on the existing architectures of CBTC and CTCS-2 signaling systems, a fusion plan for these two is proposed. Two fusion plans are compared in terms of cost investment, impact scope, renovation difficulty, and applicable range. Ultimately, the fusion plan with on-board equipment that accommodates ground equipment of both signaling systems is chosen. The ground equipment design follows the principle of ′minimizing changes to CTCS equipment while adding or modifying CBTC equipment′, and the on-board equipment design follows the principle of ′keeping ATP (automatic train protection) core equipment independent while maximizing the reuse of peripheral components′. Under the premises of ensuring system operational efficiency and compliance with CTCS-2 standards, two conversion plans are proposed, ′train conversion from CTCS-2 line to CBTC line′ and ′train conversion from CBTC line to CTCS-2 line′, aiming to achieve bidirectional interoperability between city railway CBTC and CTCS-2 systems. ［Result & Conclusion］ The research results indicate that the implementation of the chosen plan can enhance city railway transportation efficiency, optimize transportation organization and management, improve the network functionality of rail transit, and promote coordinated development between central cities and surrounding areas.
