5G宽带移动通信及北斗卫星导航技术在LKJ中的融合应用研究

Research on Fusion Application of 5G Mobile Communication and BeiDou Satellite Navigation Technology in LKJ

5G通信和卫星定位已成为推动列车运行控制系统向前发展的核心技术。基于实时动态差分的卫星定位技术可将列车定位精确至厘米级,5G通信则为车地之间的卫星差分数据传输提供高速通道。结合列车运行监控装置(LKJ)在智能控制方面的需求,采用5G+北斗导航技术,针对LKJ参数设定辅助提示、始发站开车自动对标、轮径自动校正、测距误差消除、调车作业防护等5个应用场景提出解决方案,对于提升LKJ精准高效的控制能力具有一定借鉴意义。

5G Communication and satellite positioning have become the core technologies driving the development of train operation control system in the future.Satellite positioning technology based on real-time dynamic difference can accurately position trains to the centimeter level,and 5G communication provides a high speed channel for satellite differential data transmission between trains and ground.Combined with the intelligent control requirements of LKJ,the 5G+BeiDou navigation technology is adopted,the solutions are put forward in five aspects,including auxiliary prompts for LKJ parameter setting,automatic calibration of departure station,automatic correction of wheel diameter,elimination of distance measurement errors,and protection of shunting operations.This research has certain reference significance for improving the accuracy and efficiency control of LKJ.
