A mileage mark is required to be established every certain distance on a common railway line. The established mile marks generally comprise hectometer marks, curve key point marks (including such as straight slow point marks, slow circle point marks, circle slow point marks, slow straight point marks and the like), bridge marks, tunnel marks and the like. In the operation process of the railway line, the mileage log on the railway line deviates from the originally established position of the mileage log due to the influence of factors such as the extension of the operation time, the maintenance of the continuous railway line, the drift of the railway line and the like, and the deviation amount is small and may be several meters to tens of meters, so the deviation amount accumulated by a plurality of points is large. Due to the factors, a plurality of mileage milestones on the current common railway line can not correspond to the actual mileage milestone positions, the reference values of the mileage milestones are lost, and railway maintenance personnel can not be accurately guided to accurately confirm the positions of the railway maintenance personnel.
In the past, the mode of manually updating and correcting the milestones is mostly adopted, namely, workers verify and confirm and correct and update the positions of the milestones one by one along a railway line. Therefore, the means for verifying, correcting and updating the milestones by the staff specially patrols along the railway line needs to continuously patrol along the railway line at high frequency if the position of the milestone is accurate, so that the operation causes the workload of the staff to be very large and is difficult to operate and implement in the actual situation.
