复杂站型CTC系统自动排路优化技术方案

Optimizing Technique Solution to Automatic Route Setting of CTC System for Complex Station

复杂、多方向站型条件下,CTC系统在同时满足行车及运输互通的条件下很难实现自动排列进路的功能,使得CTC系统功能没有得到彻底地发挥,既不满足相关技术条件,也降低了行车运输的自动化程度。文章将广元兰渝宝成场CTC系统的设计方案作为一个范例,在站型不变的前提下,将站场、行车运输、信号等专业设计综合考虑,从运输效率、安全性、经济性、系统复杂性等方面入手,通过比较不同的信号设计方案,给出了最佳的现场CTC系统实现方案,达到了在复杂站场环境下既满足运输需求又实现自动排路功能的目的。

At a station with complex arrangement and multi-directional train operation,it is difficult for the CTC system to realize automatic route setting by satisfying the condition of traffic operation and the intereonnection of traffic transportation at the same time.Thus,the CTC system cannot play its full roles so that related technical requirements cannot be met and the level of traffic automation will be lowered.Taking the design scheme of the CTC system of the yard at Guangyuan station connecting Lanzhou-Chongqing railway and Baoji-Chengdu railway as example,an optimum implementation plan of the CTC system is proposed by comparing deferent designs of the signalling system in term of transportation efficiency,safety,economy and system complexity.The requirements from the disciplines of station design,traffic planning and signalling design have been taken into the consideration of the plan on the premise of not changing station arrangement,hence achieving the purpose of meeting transportation demand and realizing automatic route setting at a complex station.
