摘要:
DCS（数据通信子系统）为CBTC（基于通信的列车控制）信号系统内其他子系统提供安全、可靠的数据交换服务，是CBTC的通信基础。对上海城市轨道交通CBTC信号系统线路进行了研究，首先介绍了既有DCS的功能和基本网络架构，阐述了DCS在CBTC系统中的重要性；然后结合实际城市轨道交通信号项目的现状，分析了既有DCS在上海城市轨道交通系统中的应用及存在的问题，提出了DCS在冗余性、网络性能和可扩展性的优化方案，建立优化后的DCS网络架构；最后，结合研究成果，指出了未来DCS的发展方向。
Abstracts:
DCS (data communication subsystem) provides safe and reliable data exchange services for the other subsystems in the CBTC (communication-based train control) signaling system, which is the communication basis of the entire CBTC system. Research is carried out on Shanghai urban rail transit CBTC signaling system. Firstly, functionality and basic network architecture of the existing DCS are introduced, and the importance of DCS to the CBTC system is expounded. Then, considering the current situation of actual urban rail transit signaling projects, the application and existing problems of current DCS in Shanghai urban rail transit signaling system are analyzed, and optimization plan for DCS in redundancy, network performance and scalability is put forward, and optimized DCS network architecture is established. Finally, combined with the previous analysis results, future development direction of DCS is explained.
