广州地铁1号线信号系统改造中站台门联动控制的技术研究

Research on Linkage Control Technology of Platform Screen Door Under Reconstruction in Signalling System of Guangzhou Metro’s Line NO.1

针对城市轨道交通既有线路信号系统改造时涉及的站台门联动控制相关技术问题,以广州地铁1号线为例,从命令同步、车地通信、状态表示、对外接口等方面进行了阐述;从兼容性、安全性、维护成本三个角度对比分析了改造前、后的系统特点,能够为其他轨道交通线路同类系统改造提供参考与借鉴。

In view of the technical problems related to the platform door linkage control involved in the transformation of the signal system in existing line of urban rail transit,the command synchronization,vehicle-ground communication,state representation,external interface and other aspects are described by taking Guangzhou metro line No.1 as an example.The characteristics of the system before and after the transformation are compared from the perspectives of compatibility,safety and maintenance cost,providing reference for similar technical transformation of other rail transit lines.
