深圳地铁2号线列车自主化牵引系统在列车自动运行模式下冲标问题分析

Analysis of Stop Mark Exceeding Problem of Shenzhen Metro Line 2 Train Independent Traction System under ATO Mode

ATO(列车自动运行)模式下列车停车对标不准问题涉及多个系统,原因较复杂。以深圳地铁2号线T 240车自主化牵引系统在运营过程中发生冲标问题为实例,阐明了ATO模式下对标停车的基本原理。在此基础上,重点对牵引系统可能引起对标不准的几个原因进行深入剖析,详细分析了案例列车冲标的具体原因及所采取的整改措施,并通过正线试验验证了整改措施的可行性。

The problem of train inaccurate parking under ATO(automatic train operation)mode involves multiple systems,and the causes are complex.Based on the actual case of Shenzhen Metro Line 2 T240 train independent traction system encountering the problem of stop mark exceeding during operation,the basic principle of accurate parking under ATO mode is elaborated.On this basis,several reasons of traction system potentially causing inaccurate parking are analyzed in-depth.Specific reasons and the corrective measures taken for train stop mark exceeding in the study case are expounded.Finally,the feasibility of the rectification measures is verified through main line test.
