动车组进站掉码问题分析及改进措施

Problem Analysis of Code Missing and Improvement Measures When EMU Entering Stations

针对动车组在普速车站越过进站信号机内方区段发生掉码并紧急制动问题,经过对该场景掉码原因从车载数据和地面数据深入分析,提出延长进站信号机内方第一区段的区段长度的整治建议,以此为其他涉高车站的设计和施工提供参考,减少该场景下的动车组掉码情况。

For the occurrence of code missing and emergency braking problems when EMU running over the section in rear of a home signal at the conventional speed station,after in-depth analysis of the cause of code missing in this scenario from onboard data and ground data,the paper puts forward the improvement suggestion of extending the length of the first section in rear of a home signal,which can provide reference for the design and construction of other high speed related stations,and reduce the situation of EMU code missing in this scenario.
