Problems solved by technology

[0002] Existing line measurement is to provide accurate and reliable technical data for the operation management, maintenance, repair, technical transformation and reconstruction of existing railways; during the operation of existing line railways, track measurement is usually carried out after CPIII retesting, but the , the skylight time is short, if the track measurement is carried out after the CPIII retest measurement results are completed, the construction period will be doubled, which also seriously restricts the track measurement efficiency
At the same time, for new lines with tight construction schedules, if the method of track measurement after CPIII retest is still adopted, it will inevitably affect the progress of the project

Embodiment Construction

[0015] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below with reference to the accompanying drawings.

[0016] like figure 1 As shown, a post-processing method for orbit measurement of the present invention comprises the following steps:

[0017] Step 1: Store the CPIII results of the previous stage (CPIII point number, coordinate X, coordinate Y, coordinate H, instrument height, as shown in Table 1) on the data acquisition device;

[0018] Table 1: Results of the previous stage of CPIII

[0019]

[0020] Step 2: When using the CPIII results of the previous stage to measure the orbit, record the name of the site, the name of the target point, the measured slant distance, the horizontal angle and the zenith distance information (as shown in Table 2), no matter how big the CPIII residual is. This piece of information should be measured and saved, ...

Abstract

The invention discloses a post-processing method for orbit measurement, which is applied to the technical field of engineering surveying and mapping. In view of the problem that the existing orbit measurement is usually carried out after CPIII re-measurement, the existing orbit measurement efficiency is low; Measurement and CPIII re-measurement; the preliminary orbit measurement is carried out with the CPIII results of the previous stage; the CPIII results of the previous stage are the network construction results or the last CPIII re-measurement results; the preliminary orbit measurement results can basically reflect the actual situation of the orbit, if there is any deviation If the area is too large, find the cause in time, and reserve time for the problem to be solved. After the current retest results are completed, the final fastener purchase quantity will be submitted in time, thereby shortening the material preparation period and improving the project progress; in the existing line survey, use CPIII The track measurement of the network construction results can be carried out at the same time as the CPIII re-measurement, which reduces the number of guards and the overall time on the road, so as to reduce the measurement cost.

Description

technical field [0001] The invention belongs to the technical field of engineering surveying and mapping, in particular to a track surveying technology. Background technique [0002] Existing line survey is the technical data that provides accurate and reliable for the operation management, maintenance, repair, technical transformation and reconstruction of existing railways; during the operation of , the skylight time is short, if the orbital measurement is performed after the CPIII re-measurement results are completed, the construction period will be doubled, which also seriously restricts the orbital measurement efficiency. At the same time, if the new line with tight construction period still adopts the method of track measurement after CPIII re-measurement, it will inevitably affect the progress of the project. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problems, the present invention proposes a post-processing method for orbit ...
