The invention discloses a method for correcting a parking space during installation deviation of a positioning antenna, which comprises the following steps of: measuring a longitudinal distance and a transverse distance of a locomotive antenna deviating from a locomotive head center point at an I end of a locomotive, and setting the longitudinal distance and the transverse distance as configuration parameters; the Beidou coordinate values are converted into coordinate values in a rectangular coordinate system through a Miller projection method, and the orientation of a station track in a real longitude and latitude map is judged according to the change trend of station track surveying and mapping data in a station yard schematic diagram; in a rectangular coordinate system, judging whether a locomotive coordinate point is above or below a station track by using a formula; according to the up and down azimuth information of the locomotive coordinate point, the locomotive I end locomotive head orientation, the station track orientation and the antenna configuration parameter information, the vertical line distance of each station track in the station yard graph is subjected to addition and subtraction compensation, the station track corresponding to the minimum vertical line distance value is solved, the station track position where the locomotive head is located is calculated, and the influence of the antenna installation position can be effectively eliminated; and the real-time positioning accuracy and the matching success rate of the locomotive are improved.

    本发明公开了一种运用于定位天线安装偏移时矫正车位的方法,包括测量机车天线偏离机车I端车头中心点的纵向距离和横向距离,设定为配置参数;用米勒投影法将北斗坐标值转换为直角坐标系中的坐标值,依据站场示意图中股道测绘数据的变化趋势,判断股道在真实经纬度地图中的朝向;在直角坐标系中,用公式判断出机车坐标点在股道的上方还是下方;根据机车坐标点上下方位信息、机车I端车头朝向、股道朝向和天线配置参数信息,将站场图中每个股道的垂线距离进行加减补偿,求垂线距离值最小时对应的股道,计算出车头所在股道位置,可以有效地消除天线安装位置的影响,提高机车实时定位的准确度和匹配成功率。
