The invention discloses a train positioning system combining instant positioning and map construction. The train positioning system comprises a beacon database, a vehicle-mounted controller and a positioning correction module, wherein beacon data is stored in the beacon database; the vehicle-mounted controller is provided with a beacon recognition module and a speed acquisition module, and train mileage data, train section positioning information and train real-time speed are sent to the positioning correction module; and the positioning correction module comprises an environment sensing sensor and a vehicle-mounted data processor, and the vehicle-mounted data processor obtains the position of the train through the SLAM technology according to the environment information and achieves positioning correction in combination with data provided by the vehicle-mounted controller. The invention further provides a train positioning method, and the train positioning system is adopted for positioning. According to the method, the train positioning precision is improved, positioning is carried out without depending on satellite signals, the application scene is wide, meanwhile, new beacons and trackside equipment do not need to be added, and the maintenance cost is low.

    本发明公开了一种结合即时定位与地图构建的列车定位系统,包括信标数据库、车载控制器、定位修正模块:信标数据库中存储有信标数据;车载控制器设有信标识别模块、速度获取模块,将列车里程数据、列车区段定位信息以及列车实时速度发送给定位修正模块;定位修正模块包括环境感知传感器和车载数据处理器,车载数据处理器根据环境信息,利用SLAM技术获取列车的位置,并结合车载控制器提供的数据,实现定位修正。本发明还提供了一种列车定位方法,采用所述的列车定位系统进行定位。本发明不仅实现了列车定位精度的提高,而且不依赖卫星信号进行定位,适用场景较广,同时也不需要新增信标和轨旁设备,维护成本较低。
