Method for ensuring consistency of road plane and longitudinal section data and relevant data of road plane and longitudinal section data

Abstract

The invention discloses a method for ensuring consistency of road plane and longitudinal section data and relevant data of road plane and longitudinal section data. Road plane version relevant data comprise plane line metadata, road longitudinal section version relevant data comprise gradient change point data, plane version information is attached to the plane line metadata, and longitudinal section version information is attached to the gradient change point data. When the plane line metadata are changed, the plane version information is updated, and the plane version information before change is attached at the same time. When the gradient change point data are changed, the longitudinal section version information is updated, and the longitudinal section version information before change is attached at the same time. By means of the method for ensuring the consistency of road plane and longitudinal section data and relevant data of road plane and longitudinal section data, whether the data are modified is not needed to be memorized manually, the design quality is improved, the historical data can be traced, and the data consistency is ensured.

Description

technical field [0001] The invention relates to the field of road route design, in particular to a method for ensuring the consistency of road plane and longitudinal planes and related data. Background technique [0002] Road route design mainly includes three parts: plane design, longitudinal section design and cross section design. Road route design involves a lot of basic data, all kinds of data are interrelated and affect each other, and the design is often revised repeatedly. [0003] Plane design is the basis of the whole route design, it affects every aspect of highway design, and its result is plane line metadata. If the plane line element is modified, the associated data such as broken link data, plane intersection point data, slope change point data, longitudinal section ground line, and cross section ground line will all change accordingly. The longitudinal section design is completed on the basis of the planar design, so it depends on the planar design, and the...

AI Technical Summary

Problems solved by technology

In the existing road CAD design software, there is no correlation between various data. After one or several types of data are modified, the software system cannot guarantee the consistency of related data, nor can it remind users to modify other related data to use keep consistent

Therefore, after the metadata of the plane line or the data of the slope change point is changed, the user needs to ensure that other relevant data have been modified to be consistent with it, so it is difficult to guarantee the correctness of the output design results

If the relevant data is not modified due to the designer's negligence, omission, etc., the final design result is incorrect, which often leads to design repetition or engineering changes
