单线铁路提速区段列车控制系统方案研究

Research on the Plan of Train Control System in Speed-up Sections on Single-track Line

针对单线铁路提速至120km/h以上带来的新问题,分析信号系统的技术性、安全性、经济性和可行性。在充分利用目前国内外先进、成熟的信号技术和设备的基础上,提出适合我国单线提速铁路的列车控制的系统方案:采用双接近区段+点式应答器+主体机车信号与列车运行监控记录装置相结合的集成系统。

Technology, safety, economy and feasibility of the signaling system are analyzed to tackle a series of new issues emerged while increasing the speed of existing single-track railway to 120km/h or above. By fully introducing domestic and foreign leading and proven signaling technologies and equipment, train control solution adapted to speed-increased single-track railway is proposed, which is an integrated system combining train operation monitoring and recording device as well as double-approach section + intermittent balise + cab signal of master locomotive.
