The invention relates to accurate positioning of a freight train, in particular to a positioning method and device which are invented for solving the problem of low carrying efficiency caused by inaccurate positioning when a train loads goods and dispatches, and particularly relates to a method and device for improving real-time positioning accuracy of a railway freight train. The positioning device comprises a Beidou positioning module installed in a cab, a data processing module installed in the cab, and a data display module and a data transmission module which are installed in the cab. The positioning method comprises the following steps: establishing a geodetic coordinate system, numbering vehicles, acquiring locomotive coordinates through the Beidou positioning module, converting longitude and latitude coordinates into geodetic coordinates, performing calculation processing for multiple times by adopting a simulated spherical surface and a simulated track, converting the geodetic coordinates of the vehicles into the longitude and latitude coordinates, and performing positioning. And repeating the steps to obtain real-time latitude and longitude coordinate information of all n sections of vehicles. Therefore, cargo loading and transporting efficiency of the freight train can be improved, train dispatching and commanding are facilitated, and loss of manpower and material resources is reduced.
本发明涉及到货运列车车辆精确定位,具体涉及到为解决在列车装载货物和调度时由于定位不准而造成的运载效率低下的问题而发明的一种定位方法及装置,尤其涉及一种提高铁路货车车辆实时定位精度的方法及装置。定位装置包括安装在司机室的北斗定位模块、安装在司机室的数据处理模块、安装在司机室的数据显示模块和数据传输模块。定位方法步骤为,建立大地坐标系并对车辆进行编号,通过北斗定位模块获知机车坐标后,将经纬度坐标转换为大地坐标,采用模拟球面和模拟轨道进行多次计算处理,之后将所得车辆的大地坐标转换为经纬度坐标,重复以上步骤得到全部的n节车辆的实时经纬度坐标信息。如此可以提高货运列车装载货物和运输效率,方便列车调度指挥,减少人力物力的损耗。
