The invention provides a train positioning correction method based on virtual transponders, and the method comprises the steps: taking the positioning precision of a positioning system as the radius,and taking a plurality of circular regions, which are the distances between adjacent circle centers, as the capturing range of a single virtual transponder, and the correction method comprises the steps of: determining the total number of the circular regions; positioning and capturing the single virtual transponder according to the actual position positioned by the positioning system; and determining the circular region where the position is located and triggering the corresponding virtual responder message, and at the same time, giving the value of the effective confidence interval of positioning correction. According to the invention, the relatively accurate and the reliable confidence interval result can be given, and the effective replacement of the entity transponder is truly realized.

    本发明提供一种基于虚拟应答器的列车定位校正方法,所述方法中,以定位系统定位精度为半径、且为相邻圆心间的距离的若干个圆形区域作为单个虚拟应答器的捕捉范围,所述校正方法包括步骤:确定所述圆形区域的总个数;根据定位系统定位的实际位置进行所述单个虚拟应答器定位捕捉,确定所述位置所在的圆形区域并触发相应的虚拟应答器报文,并同时给出定位校正的有效置信区间的取值,本发明给出相对精确可靠的置信区间结果,真正实现了对实体应答器的有效性替换。
