摘要
随着列车运行速度的不断加快,列车发车间隔时间越来越短,列车的精准位置信息成为保证列车行车安全的必要条件。文章在现有列车定位方式下,首先采取组合定位方式,利用速度传感器、加速度传感器、现有的轨道电路和查询/应答器,取得列车位置的多源信息;其次,通过数据融合方法将获取的多源数据信息进行处理;最后,经过仿真软件对方法进行验证。仿真结果表明,文章采取的多源信息融合的列车定位方法能明显减少定位误差,提高列车定位精度,从精确性、连续性、可维护性及安全性多方面提高列车定位性能。
With the continuous acceleration of train running speed,the interval between train departures is getting shorter and shorter,and the accurate location information of the train has become a necessary condition to ensure the safety of the train.In this paper,it is considered that under the existing train positioning mode,a combined positioning mode is adopted,and the multi-source information of train position is obtained by using a speed sensor,an acceleration sensor,an existing track circuit and an inquiry/transponder.Then,the multi-source data information obtained is processed through the data fusion method,and finally the method is verified by the simulation software.The simulation results show that the train positioning method of multi-source information fusion adopted in this paper can significantly reduce the positioning error,improve the train positioning accuracy,and improve the train positioning performance from the aspects of accuracy,continuity,maintainability and safety.
