ATP车载设备自动过分相问题分析

Problem Analysis of Automatic Passing Neutral Zone of On-board ATP Equipment

装备CTCS-3级列控车载设备的动车组在运营中由ATP控制自动过分相。对装备300H型ATP的动车组在多种场景下发生的过分相问题进行分析;阐述了ATP车载设备在C2/C3等级下控制自动过分相的工作原理;从ATP逻辑处理角度,对可能出现的带电过分相及执行假分相的原因进行针对性研究;对后续如何避免该问题提出可行性解决方案。

For EMUs equipped with on-board CTCS-3 train control equipment,ATP is responsible for controlling automatic passing neutral zone during operation.This paper analyzes some problems of passing neutral zone of EMU equipped with 300H ATP under various scenarios and briefly expounds the working principle of automatic passing neutral zone controlled by on-board ATP equipment working at C2/C3 level.From the perspective of ATP logic processing,a targeted study is made on the causes of potential abnormalities such as passing neutral zone under power load and passing pseudo neutral zone.And feasible solutions are put forward on how to avoid those problems in the future.
