The invention discloses a locomotive benchmarking method and system based on UWB positioning. According to position information of a UWB base stations and a real-time distance between a UWB label andeach UWB base station, the real-time spatial position of the UWB label under a WGS coordinate system or a three-dimensional coordinate system can be obtained. The real-time speed of a locomotive can be obtained according to a sampling period and the real-time spatial position of the UWB label, and finally a traction/braking force required for locomotive pull-in benchmarking is calculated accordingto the real-time spatial position of the UWB label and the real-time speed of the locomotive, so that traction/braking control over the locomotive is realized, and accurate benchmarking parking is realized; for locomotives, especially locomotives running on curved tracks, the benchmarking method can more accurately obtain the spatial position information of the UWB labels under a WGS coordinate system or a three-dimensional coordinate system, and more accurately realize positioning and speed measurement of the locomotives, thereby realizing one-time accurate benchmarking and parking of the locomotives.
本发明公开了一种基于UWB定位的机车对标方法及系统,根据UWB基站的位置信息以及UWB标签与各UWB基站之间的实时距离可以得到UWB标签在WGS坐标系下或三维坐标系下的实时空间位置,再根据采样周期和UWB标签的实时空间位置可以得到机车的实时速度,最后根据UWB标签的实时空间位置和机车的实时速度计算出机车进站对标所需牵引/制动力的大小,实现对车辆的牵引/制动控制,从而实现精确对标停车;对于机车,尤其是在曲线轨道上运行的机车,所述对标方法可以更为精确地得到UWB标签在WGS坐标系下或三维坐标系下的空间位置信息,更为精确地实现机车的定位和测速,从而实现机车一次性精准对标和停车。
