摘　　要：针对转速传感器在测速轮对空转、轮滑状态下存在测速测距不准确的问题,LKJ-15型列车运行监控系统中利用雷达、GPS/BDS、地面应答器信息、轨道信号、CIR等多种测速测距信息融合,实现列车测速定位功能。实际应用表明,该方案提升了列控车载系统测速定位的精度和自动化程度,减少了人工对设备的干预以及由此带来的风险。In order to solve the problem of inaccurate speed and distance measurement under the condition of idling and roller skidding of speed measuring wheels by using speed sensor, the speed and distance measurement information fusion of radar, GPS/BDS, ground transponder information, track signal and CIR was used in LKJ-15 train operation monitoring system to realize the speed and location function of train. The practical application showed that the scheme improved the accuracy and automation of speed measurement and positioning of train control vehicle system, and reduced the manual intervention to equipment and the risk caused by it.
