摘要
基于高速铁路临时限速系统原理和既有相关规范及文件,深入分析高速铁路临时限速列控设置存在的安全风险.针对因设置时机不当造成的动车组列车在限速区段超速运行,及列车超速防护系统(ATP)输出紧急制动可能造成车轮磨损或钢轨擦伤的安全风险,通过仿真计算,得出当前主要型号动车组的制动距离,并在此基础上,确定临时限速列控设置的时机.同时,结合中国铁路南昌局集团有限公司运营实践,提出高速铁路临时限速情况下动车组司机操纵作业流程,以及临时限速"接令防漏收、过程防超速、继乘防漏交"等可推广、可操作的具体建议.
Abstract
Based on the temporary speed restriction system for high speed railways,as well as existing relevant standards and documents,this paper carries out in-depth analysis of the safety risks associated with the settings of temporary speed restrictions for train control.In response to the safety risks posed by improper time setting of temporary speed restrictions,which may lead to EMU trains exceeding speed limits in restricted zones,as well as potential wheel wear or wheel burn caused by the ATP system's application of emergency braking,this study employs simulation calculations to determine the stopping distances of the primary models of EMUs and establishes the optimal timing for the implementation of temporary speed restriction for train control based on these findings.In conjunction with the operational practices of China Railway Nanchang Group Co.,Ltd.,this study proposes an operational workflow for EMU drivers under temporary speed restrictions and offers specific and practical recommendations that can be promoted and implemented,focusing on aspects such as preventing the omission of speed restriction instructions,controlling the speed during the process,and preventing the transfer of missed speed restriction information in subsequent operations.
