京津城际及其延伸线信号接口方案研究和应用

Research and Application of Signal Interface of Beijing-Tianjin Intercity Line and Its extension line

京津城际信号系统技术标准与国内其他高速铁路标准不同,其延伸线接口方案相对比较复杂,尤其是天津站城际场的衔接非常关键。为此,研究CTC系统和列控系统的接口方案,包括CTC进路自动触发、站间信息透明、车次号传输,以及临时限速处理、应答器报文设置等。

The technical standard of signaling system for Beijing--Tianjin intercity line is differ ent with that of other domestic high-speed lines, which makes the interface solution with its ex tension line more complicated, especially the connection with Tianjin Intercity Yard. The inter face solution of the CTC subsystem and train operation control subsystem is studied, includes au tomatic triggering of route, transparency of inter-station information and train number transmis sion, and temporary speed restriction handling, balise telegraph setting, etc.
