上海轨道交通3、4号线信号系统改造方案研究

Research on Signaling System Transformation Scheme of Shanghai Urban Rail Transit Line 3/4

自1993年以来,上海城市轨道交通已运营近28年。部分老线已无法满足高密度、高可靠性和高性能的超大规模网络化运营需要。因此,需要通过信号系统改造来解决信号制式落后、设备老化和技术支持薄弱等问题,以提高运营服务质量。以上海轨道交通3、4号线信号系统改造为例,从需求、工期、影响和效益等多维度考量,对信号系统改造项目的前期分析与方案比选进行了研究,最后推荐基于车车通信的列车自主控制系统作为上海轨道交通3、4号线信号系统的改造方案。

Since 1993,Shanghai Urban Rail Transit has been in operation for nearly 28 years,and some old lines have been unable to meet the need of Shanghai's high density,high reliability and high performance super large-scale network operation.Therefore,the problems of backward signaling system,aging equipment and weak technical support need to be solved through signaling system transformation to improve the operation service quality.Taking the signaling system transformation of Shanghai Metro Line 3/4 as an example,from the perspective of multiple dimensions including demand,construction period,impact and benefit,the preliminary analysis and scheme comparison of the signaling system transformation project is studied.Finally,it is recommended to adopt CBTC train control system as the transformation scheme for Shanghai Metro Line 3/4.
