摘　　要：我国城市轨道交通早期建设开通的列车控制系统已经进入不稳定期,如何保证地铁线路的稳定运营,并顺利完成系统改造过渡,已经成为地铁运营单位的首要工作。本文基于当前城市轨道交通信号领域发展现状,针对采用传统轨道电路制式线路的信号系统大修改造所面临的问题,概述了信号系统改造方案的先决条件,归纳并提出了4种可行的改造方案,分析了其存在的优缺点及适用范围,最后从用户角度提出了影响改造方案制定和实施的几点关键因素,为地铁用户在进行系统改造时降低投资概算和系统改造平稳过渡拓宽了思路。The automatic train control system,the core equipment of subway lines built and opened in the early stage of urban rail transit in China,has entered an unstable period.How to ensure the stable operation of subway lines and successfully complete the reconstruction and transition of those systems has become the primary problem for subway operators.Based on the current development situation of the signal system for urban rail transit,the preconditions of signal system’reconstruction are summarized to deal with the overhaul and reconstruction problems of the signal systems of the lines which adopt traditional track circuit.Meanwhile,several feasible reconstruction schemes are concluded and proposed with an analysis of their advantages,disadvantages and applicable scopes.In the end,key factors which may influence scheme making and implementation from the perspective of the metro users are raised,broadening the thoughts for reducing the budget estimate of such a reconstruction project and making a smooth transition during the reconstruction.
