摘要:
介绍了CBTC(基于通信的列车控制)列车定位系统的应用现状及局限性,进而分析了基于GNSS-INS(全球卫星导航系统\|惯性导航系统)的列车定位系统以及基于HDMAP(高精电子地图)和图像识别的辅助定位系统,并以此为基础提出了组合定位系统。组合定位系统具有更主动的定位方式、更高的冗余性和定位精度。
Abstracts:
The current application status and limitations of CBTC (Communication-Based Train Control) train positioning system are introduced, then the train positioning system based on GNSS-INS and the train auxiliary positioning system based on HDMAP and image recognition are analyzed, on the foundation of which a combined positioning system is proposed. This combined positioning system has more active positioning mode, higher redundancy and positioning accuracy.
