摘要
分析了城市轨道交通传统CBTC(基于通信的列车控制)系统的系统架构、各子系统的安全完整性等级,以及存在的主要问题。提出了基于车-车通信和基于联锁列控一体化两种不同系统设计理念的CBTC系统。对两种系统从系统结构、性能、成本、维护、后备模式、兼容性等6个方面进行了分析比较,认为基于联锁列控一体化的CBTC系统更适合成为我国新一代城市轨道交通信号系统。
The system architecture of the traditional urban rail transit CBTC (communication based train control) system, the safety integrity level of each subsystem, and the main problems exist in the system are analyzed.On this basis, two CBTC systems based on different system design concepts: the vehicle- vehicle communication and the interlocking train control integration are proposed.The two systems are analyzed and compared from aspects of system structure, performance, cost, maintenance, backup mode and compatibility, the CBTC system based on the interlocking train control integration is considered more suitable to become the next generation urban rail transit signal system in China.
