摘要/Abstract

摘要： 张吉怀高铁沙堤所至张家界西黔张常场联络线上CTCS-3转CTCS-2级间切换过程中，设置特定的临时限速时部分车载会触发最大常用制动。针对上述场景，分析问题成因，并结合地面、车载设备的匹配关系对解决方案进行探讨。

关键词: 级间切换, 临时限速, 最大常用制动

Abstract: In the process of transition from CTCS-3 to CTCS-2 on the connection line between Zhang-jiajie-Jishou-Huaihua high-speed railway Shadisuo station and Zhangjiajie West Qianzhangchang field, when a specific temporary speed limit is set, some onboard equipment will trigger the maximum service braking. In view of the above scenarios, this paper analyzes the reasons behind the problem and solutions are discussed in terms of the matching relationship between ground and onboard equipment.

Key words: level transition, temporary speed limit, maximum service braking
