摘　　要：朔黄铁路发生了两起安装有LKJ-15C型列车运行监控系统(以下简称LKJ-15C系统)的机车在列车始发车站北斗卫星自动开车对标失败事件。深入研究北斗卫星自动开车对标失败问题,通过分析记录文件和现场勘察推断出问题的原因,并在此基础上提出技术优化方案,优化LKJ-15C系统北斗卫星自动开车对标功能的相关硬件和软件逻辑,以提高北斗卫星自动开车对标成功的概率。In Shuohuang Railway,there were two failures of the locomotive equipped with LKJ-15C train operation monitoring system(hereinafter referred to as LKJ-15C system)at the train departure station.This paper deeply studies the failure of Beidou satellite automatic driving benchmarking,and finds out the cause of the problem by analyzing records and field investigation.On this basis,a technical optimization scheme is proposed to optimize the related hardware and software logic of the Beidou satellite automatic driving benchmarking function of LKJ-15C system,so as to improve the probability of success of Beidou satellite automatic driving benchmarking.
