The invention provides a train redundancy positioning method and device. The method comprises the steps that the head end and the tail end of a train are determined; the positioning systems at the head end and the tail end are used for positioning the position of the train, and errors between the positions positioned by the positioning systems at the head end and the tail end are obtained; and under the condition that the error is smaller than a threshold value, if the positioning system at the head end breaks down, the positioning system at the tail end is used for positioning the position of the train. According to the invention, under the condition that the head and tail end positioning systems are normal, positioning redundancy is realized, and the positioning accuracy is improved; when the positioning system at one end breaks down, the position information at the other end can be used, normal operation of the train is guaranteed, the operation efficiency is improved, and the operation cost is reduced.
本发明提供一种列车冗余定位方法及装置,该方法包括:确定列车的首端和尾端;使用所述首端和尾端的定位系统分别定位所述列车的位置,并获取所述首端和尾端的定位系统定位的位置之间的误差;在所述误差小于阈值的情况下,若所述首端的定位系统故障,则使用所述尾端的定位系统定位所述列车的位置。本发明在首尾端定位系统均正常的情况下实现定位冗余,提高定位的准确性;当一端定位系统出现故障时,可使用另一端位置信息,保证列车正常运行,调高了运营效率,降低了运营成本。
