通辽铁路枢纽内站(场)间信号结合设计处理措施

Treatment Measures for Signalling Combination Design between Stations(Yards) within Tongliao Railway Terminal

解决好铁路枢纽内两站(场)间联络线较短时信号系统的接口设计问题是确保行车安全的重要因素之一。以通辽枢纽扩能改造工程中的通辽北、哲里木站间及通辽站客、货场间信号结合设计为例,介绍综合考虑既有设备概况、联锁制式、行车效率及运营管理等多方面因素,对信号机的布置、闭塞方式办理、显示关系、电码化设置、信号机点灯电路等问题进行的应用研究,以及解决问题的具体措施。1年多的运营实践证明,系统稳定可靠,运行良好。

Interface design of signaling system is one of the important factors to ensure railway operation safety when the connection line between two stations(yards) within a railway terminal is shorter.This article takes the signaling combination designs as the examples,which are between Northern Tongliao Station and Zhelimu Station,between Tongliao Passenger Station and Tongliao Freight Yard in the project of Tongliao Railway Terminal capacity expansion and reconstruction.And then this article introduces the comprehensive consideration on the existing equipment status,interlocking system,driving efficiency,operation management and other factors,researches the signaling layout,block system,displaying relationship,coding set,signal lighting circuit and other problems,and finally puts forward specific solutions.More than a year of operation practice proves that the system is stable and reliable with well operation status.
