摘　　要：为满足高速铁路联调联试需求,研究CRH380型动车组在ATP设备隔离运行的特殊情况下,通过对列车运行监控装置(LKJ)和轨道电路读取器(TCR)进行技术改造和软件开发,并临时安装于动车组上,分别从TCR设备获取机车信号信息,从列控车载设备(ATP)速度传感器获取速度信号信息,从LKJ预存线路数据获取信号机位置及线路限速、坡道、曲线等信息,最终实现CRH380型动车组在新开通高速铁路上开展高速试验时,通过LKJ设备显示动车组工况、列车运行速度、信号机位置及线路限速、坡道、曲线等信息,为司机操作提供有效指导,辅助司机安全操纵。To meet the requirements for integrated commissioning&test of high speed railways,this paper explores the technical solution for the CRH380 EMU train under the special circumstance of operation with isolated onboard train control equipment(ATP).The study involves technical modifications and software development for the train operation monitoring device(LKJ)and the track circuit reader(TCR),which are temporarily installed on the EMU train.Locomotive signal data is obtained from the TCR,while speed signal data is sourced from the ATP’s speed sensor.Additionally,information such as signal locations,speed restrictions,slopes and curves is derived from pre-stored line data within the LKJ.This arrangement facilitates the display of the operating conditions of the CRH380 EMU,as well as train running speeds,signal locations,speed restrictions,slopes and curves during high-speed testing on newly opened high speed railway lines,which provides effective guidance to the driver and contributes to safe operation.
