High speed railway mileage benchmarking method
The invention belongs to the field of detection of high speed railway tracks, and relates to a high speed railway mileage benchmarking method. The high speed railway mileage benchmarking method comprises the following steps of 1.1) acquiring and processing data by a mileage meter; 1.2) acquiring initial mileage data; 1.3) calculating the mileage; 1.4) acquiring data by a satellite; 1.5) acquiring coordinate-mileage database data of the track; 1.6) performing correction on mileage benchmarking. According to the invention, the positioning technology combining the high-resolution photoelectric mileage meter and the high-precision difference satellite is adopted, thus high speed railway mileage positioning accuracy is higher than 0.1m at multiple conditions of main tracks, bridges, tunnels and the like and less than the layering interval of 0.625m between sleepers, the track fault can be accurately positioned to a concrete sleeper, and therefore the working efficiency of maintenance and detection is improved.
