The invention provides a head and tail redundancy positioning system and method. The head and tail redundancy positioning system comprises two sets of speed and distance measuring systems arranged at the head end and the tail end of a train respectively, two sets of transponder positioning systems arranged at the head end and the tail end of the train respectively, and a train control system positioning redundancy processing unit. Wherein the speed measurement and distance measurement system comprises a plurality of different sensors, and the plurality of different sensors are used for respectively obtaining speed measurement and distance measurement data; the train control system positioning redundancy processing unit is used for carrying out train positioning based on train operation speed information and/or acceleration information and transponder information from the transponder positioning system, and the train operation speed information and/or acceleration information are/is obtained based on fusion of the speed measurement and distance measurement data.
本发明提供一种首尾冗余定位系统及方法,首尾冗余定位系统包括:分别设置于列车首端和列车尾端的两组测速测距系统、分别设置于列车首端和列车尾端的两组应答器定位系统、以及列控系统定位冗余处理单元;其中,所述测速测距系统包括多个不同的传感器,所述多个不同的传感器用于分别得到测速测距数据;所述列控系统定位冗余处理单元用于基于列车运行速度信息和/或加速度信息、以及来自所述应答器定位系统的应答器信息,进行列车定位,所述列车运行速度信息和/或加速度信息基于所述测速测距数据融合得到。
