广州地铁3号线B1型联挂列车对标不准问题分析与应对

Cause Analysis and Case Handling of Position Error of Double-Trains in Guangzhou Subway Line 3

广州地铁3号线目前使用Seltrac S40移动闭塞信号系统,车载VOBC由于在线使用数量较多并且与车辆系统存在接口关系,出现问题数量位于整个信号系统子系统的首位,其中影响最大的疑难问题是B1型联挂列车对标不准故障。经深入分析自动列车速度控制原理、车辆系统牵引/制动原理等,通过数据统计分析、原理研究、测试验证等方式,分析出该问题的相关影响因素,并提出相应的应对措施。

The Line 3of Guangzhou Metro is now operating with the Seltrac S40 signal system.Vehicle On Board Controller（VOBC）is one subsystem of the Seltrac S40 signal system.Because too many online VOBC are in use and connected to the vehicle system via interface,the problems of the VOBC top that of all the subsystems of the Seltrac S40 system.Among those problems,the most influential one is that B1 type coupled trains are out of coupling position.Based on the theory of automatic speed control and vehicle traction/braking,relevant factors of the problem are identified and corresponding measures are presented through statistical analysis,theory study and test validation.
