The invention provides a two-stage fusion perception and safety fault tolerance train speed measurement positioning system, which is characterized in that the train speed measurement positioning system comprises a first-stage fusion module group and a second-stage fusion module group, and the first-stage fusion module group comprises an inertial navigation module, a visual processing module, a first-stage data fusion module and a data correction module; and the secondary fusion module group comprises a left side module group detection module, a right side module group detection module, a front and rear side module group detection module and a secondary data fusion module. The method comprises the following steps: the primary fusion module group performs primary fusion correction on inertial navigation and visual processing data, and then the secondary fusion module group performs secondary fusion on data of each primary fusion module group without intermittent faults to obtain speed positioning data of the whole vehicle. By adopting the system and the method provided by the invention, the speed measurement and positioning accuracy of train operation can be improved, and the safety guarantee of train operation is further improved.

    本发明提供了一种两级融合感知和安全容错的列车测速定位系统,其特征在于:所述列车测速定位系统包括一级融合模块组和二级融合模块组,一级融合模块组包括惯性导航模块、视觉处理模块、一级数据融合模块和数据修正模块;二级融合模块组包括左侧模块组检测模块、右侧模块组检测模块、前后侧模块组检测模块和二级数据融合模块。所述方法包括:一级融合模块组对惯性导航和视觉处理的数据进行一级融合修正,然后二级融合模块组对各个无间歇故障的一级融合模块组的数据进行二级融合得到整车的速度定位数据。采用本发明所述的系统和方法能提高列车运行的测速定位准确性,进而提高对列车运行的安全保障。
