城市轨道交通信号系统改造方案研究

Retrofit Solution Research of Urban Rail Transit Signaling System

分析了旧线信号系统改造的必要性,阐述了改造方案的评估要素。对单系统逐步替换、新老设备兼容共存及全部设备更新换代的3种方案进行了比选。基于不同的线路改造需求,得出了各类改造方案与不同的改造需求之间的匹配关系,以获得针对不同改造需求的适应性最佳的改造方案。

The necessity of existing line retrofit is analyzed.Evaluation factors of retrofit solution are expounded.Comparative selection is conducted among three solutions that are gradual replacement of single system,compatible co-existence of new/old equipment and all equipment replacement.Based on the retrofit requirements of different lines,the matching relationship between different retrofit solutions and retrofit requirements are drawn to acquire the most adaptable retrofit solutions targeting different retrofit requirements.
