摘要
时速350km客运专线传输系统作为承载CTC调度集中、GSM-R、综合视频监控、防灾安全监控等子系统的基础传输平台,是行车安全的根本保证。文章围绕传输系统的组网方案展开讨论,从安全可靠性、生存能力、网络结构、业务扩展性、运维管理成本和工作量等方面详细分析了各种组网方案的优缺点,对时速350km客运专线传输系统组网方案提出了一些合理建议。
The transmission system for 350 km/h passenger dedicated line, as the basic transmitting platform to support sub-system such as CTC dispatching concentration, GSM-R, comprehensive video monitoring and control for accidents, has provides a guarantee for traffic operation. This paper initiates the discusses on the organization of transmission system and analyses in detail the merits and demerits of various programs from the respects of safety, reliability, survival capacity, network structure, business expansibility, cost of operation, maintenance and management and workload etc. and offers some sensible suggestions to the transmission system program on 350 km/h passenger dedicated line.
