The invention discloses a whole-line-network train positioning method based on beacons, and relates to the technical field of train positioning. According to the method, under the fault scene of CC downtime, updating and tracking of the train position of the whole line network are achieved by reading the beacon ID, providing the backup train positioning information and interacting the beacon information with the GTS, and compared with existing axle counting positioning and manual positioning schemes, the positioning precision is higher. By multiplexing the existing beacon device, the beacon ID of the beacon laid along the track is read, and the beacon ID is matched with the beacon position in the electronic map, so that the positioning of the train is realized. According to the scheme, only a small number of independent hardware devices are needed, secondary devices are few, system laying cost and maintenance cost are low, and economic benefits are obvious. Beacon laying design and position data are included in existing urban rail construction design, construction and operation difficulty and complexity do not need to be increased, an interface is simple, the reuse degree is high, and the scheme landing difficulty is low.
本发明公开了一种基于信标的全线网列车定位方法,涉及列车定位技术领域。本发明在CC宕机的故障场景下,通过读取信标ID,提供后备列车定位信息,与GTS交互信标信息,实现全线网列车位置的更新和追踪,相比既有的计轴定位和人工定位方案,定位精度的更高。通过复用既有信标设备,读取沿轨道铺设信标的信标ID,并与电子地图中的信标位置做匹配,实现列车的定位。该方案仅需少量和独立的硬件设备,次级设备少,系统铺设成本和维护成本低,经济效益明显。信标铺设设计和位置数据,包含在既有城轨施工设计中,无需增加施工和运营的难度和复杂度,接口简单,可复用程度高,方案落地难度低。
