The invention discloses a train multi-source information fusion positioning method based on 5G positioning, which fuses multi-source data information such as 5G positioning information, satellite positioning information, speed sensor information, transponder information and the like, and provides more reliable train position and speed information through redundancy complementation of the multi-source data information. The defect that positioning depends on satellite positioning and is greatly influenced by terrains and environments is overcome, and the problems that in the prior art, in the environments where satellite signals are shielded in tunnels, valleys and the like, satellite positioning fails, a system only uses a wheel axle speed sensor for speed measurement and distance measurement, and errors are large are solved.
本发明公开了一种基于5G定位的列车多源信息融合定位方法,融合了5G定位信息,卫星定位信息,速度传感器信息,应答器信息等多源数据信息,通过多源数据信息冗余互补提供了更加可靠的列车位置及速度信息。避免定位时依赖于卫星定位而受地形、环境影响大的弊端,解决了现有技术在隧道、山谷等内等卫星信号受遮挡的环境内,卫星定位失效,系统仅使用轮轴速度传感器进行测速测距,误差较大的问题。
