摘　　要：针对目前机车车载过分相方式存在的问题,文章提出一种不依赖地面设备、基于组合定位技术的自动过分相系统,从系统工作原理、定位模式判断、组合定位模型、分相点捕获等方面阐述了设计原理,并介绍了装车验证情况。验证结果表明,该系统在多数应用场景中能准确实施列车自动过分相。Aiming at the problems existing in the current locomotive with on-board neutral section passing mode,this paper puts forward an automatic neutral section passing system that does not rely on ground equipment and is based on integrated positioning technology.It expounds the design principle from the aspects of system working principle,positioning mode judgment,integrated positioning model,and phase separation point capture,and presents its installation verification situation.The verification results show that the system can accurately implement automatic train passing through neutral section in most application scenarios.
