南京地铁宁溧线信号控制4/6节编组列车混合运行技术方案

根据南京地铁宁溧线和机场线贯通运营的要求,空港新城江宁站至无想山站小交路需要支持4/6节编组列车混合运行.为此,信号系统需对车载信号和轨旁信号进行特殊设计,除在轨旁增加混合运行控制设备,并配置不同的车载数据库,实现自动识别列车编组外,还需对不同编组列车的定位、超速防护、对标停车、试车线测试以及站台门联动进行设计,增加混合运行功能,实现4/6节编组列车的安全运行控制.

Technical Scheme of Signal Control for Mixed Operation of 4/6-car trains in NingLi Line of Nanjing Metro

For the operation of NanJing Mtro's NingLi line in connection with the airport line,it is required that the short routing from Jiang Ning station at the airport new town to W uxiangshan station must support mixed operation of 4-car trains and 6-car trains.So,special designs were made to both the on-board and wayside signaling system to meet the requirement of mixed-opera-tion.By adding wayside control device for mixed-operation and equipping with different on-board databases,automatic train identification had been realized.In addition,the function of mixed operation was also added to location of trains in different form,over-speed protection,and train stop alignment,and testing line as well as linkage control of platform screen door,attaining safe operation of 4-car/6-car trains.
