摘要:
既有线信号系统的升级改造是未来城市轨道交通运维的重点工作之一。基于“既有线改造不应影响日常运营”这一原则，对既有列车车载信号系统的改造施工方案进行研究。介绍了车载信号系统改造施工前准备的主要内容，分析了既有系统改造的总体需求。重点阐述了车载设备安装及控制电路相关电气安装的施工方式、施工工序，并提出了改造施工方案测试验证的主要内容及具体要求。
Abstracts:
The upgrading of existing signal system is a key work for urban rail transit in the future. According to the principle that ′the reconstruction of existing line should not affect daily operation′, the reconstruction scheme of existing train station signal system is studied. In this paper, the main preparation works before the reconstruction of vehicle on-board signal system are introduced, and the overall requirements of the existing system reconstruction are analyzed. Then, the construction method and the installation procedure of vehicle on-board equipment, the control circuit related electrical facilities are highlighted. Finally, the main content and specific requirements for the test and verification of the reconstruction scheme are put forward.
