Description

Technical Field

[0001] The present invention relates to the technical field of highway management, and particularly to a method for integrating highway construction, management, and maintenance data and performing three-dimensional display. Background Art

[0002] With the rapid development of transportation infrastructure, highways, as an important means of transportation, have become increasingly complex in terms of their construction, management, and maintenance. Traditional two-dimensional maps and data management methods are no longer sufficient to meet the needs of modern highway management, especially in terms of data integration, information sharing, and visualization display, where there are many limitations.

[0003] In recent years, the informatization of highway management has become an inevitable trend in the industry. Traditional highway management methods have problems such as scattered data and information silos, resulting in low management efficiency. By integrating highway construction, management, and maintenance data and performing three-dimensional display, centralized management and sharing of data can be achieved, and management efficiency can be improved.

[0004] With the increasingly wide application of digital technology in the entire life cycle of highways, a large amount of data has been accumulated in highway construction and operation and maintenance management. However, due to the large amount of data, the wide scope of highways, and the distribution of data in multiple systems, it is difficult to clearly and quickly display the highway environment and technical conditions using traditional data charts, thus affecting the efficiency of operation and maintenance management. Therefore, this application proposes a method for integrating highway construction, management, and maintenance data and performing three-dimensional display to solve the problems mentioned above.

When the route direction is downhill, the position of point P1 is at the starting stake number position and on the left side of the first lane of the left side of the road. The position of point P2 is at the starting stake number position and on the right side of the second lane of the left side of the road. The position of point P3 is at the ending stake number position and on the right side of the second lane of the left side of the road. The position of point P4 is at the ending stake number position and on the left side of the first lane of the left side of the road; S7-2-3. When the route direction is uphill, the position of point P1 is at the starting stake number position and on the left side of the first lane of the right side of the road. The position of point P2 is at the starting stake number position and on the right side of the second lane of the right side of the road. The position of point P3 is at the ending stake number position and on the right side of the second lane of the right side of the road. The position of point P4 is at the ending stake number position and on the left side of the first lane of the right side of the road; S7-2-4. According to the positions of the four points P1, P2, P3, and P4 determined in S7-2-2 and S7-2-3, use the general program in S5 to obtain the coordinates and elevations of the four points.

8. A method for integrating highway construction, management, and maintenance data and performing three-dimensional display according to claim 3, characterized in that, The steps for displaying the highway disease data in the 3D model space in S8 are as follows: S8-1. Read the road disease stake numbers and disease data imported in S4-2; S8-2. Use the general program in S5 to obtain the coordinates and elevations of road diseases; S8-3. According to the coordinates and elevations obtained in S8-2, load road disease icons and disease numbers in the 3D model space; S8-4. Click on the disease icon generated in S8-3 with the mouse to view more detailed disease information.

9. A method for integrating highway construction, management, and maintenance data and performing three-dimensional display according to claim 3, characterized in that, The steps for displaying pavement maintenance data in the 3D model space in S9 are as follows: S9-1. Read the pavement maintenance data imported in S4-3; S9-2. Use the general program in S5 to obtain the coordinates and elevations of pavement maintenance; S9-3. According to the coordinates and elevations obtained in S9-2, load pavement maintenance icons and maintenance numbers in the 3D model space; S9-4. Click on the pavement maintenance icon generated in step S9-3 with the mouse to view more detailed maintenance operation information.
