摘要
根据下一代列车运行控制系统的发展趋势,青藏铁路列控系统通过采用基于卫星定位系统的列车实时定位方案取代区间大量实体应答器的部署,在降低部署和运营成本的同时,可提供列车的实时精确定位。分析卫星定位的方案,提出在使用卫星定位系统进行列车连续定位时结合车载的测速测距信息,避免列车过道岔情况下定错列车所在轨道的问题。
According to the development trend of the next-generation train operation control system,the Qinghai-Tibet Railway train control system replaces a large number of balise deployed in the section by adopting a real-time train positioning solution based on satellite positioning system.The deployment of this system can reduce the deployment and operation costs of Qinghai-Tibet Railway.At the same time,service of real-time accurate positioning of trains can be provided.This paper analyzes the satellite positioning scheme,and proposes the combination of the on-board speed and distance measurement information when the satellite positioning system is used for continuous train positioning.In this way,the problem of positioning the train at the wrong track can be avoided when the train passes through the switch.
