Description

Technical Field

[0001] The present invention belongs to the technical field of high-altitude transmission lines, and particularly relates to a three-dimensional precise modeling system and method for high-altitude transmission lines. Background Art

[0002] In high-altitude areas, the construction and operation and maintenance of transmission lines have long faced severe challenges. Due to the complex local geographical environment, traditional topographic survey methods are difficult to obtain high-precision data, resulting in the inability to accurately consider the impact of terrain factors on line layout and tower structure during the design process of transmission lines. At the same time, the meteorological conditions in high-altitude areas are changeable. The existing meteorological data collection methods not only have limited coverage but also lack real-time nature, making it difficult to meet the design and operation and maintenance requirements of transmission lines under different meteorological conditions. In terms of data processing, the previously collected geographical information, meteorological data, and transmission line parameters are often independent of each other, lacking effective integration and analysis, and unable to explore the potential connections between data to provide comprehensive support for the design of transmission lines. In addition, the accuracy of traditional transmission line modeling technology is relatively low. The tower and conductor models cannot truly reflect their actual shapes and mechanical properties in complex environments, and the scene model also lacks dynamic simulation of geographical and meteorological elements, making it difficult for designers to intuitively evaluate the rationality of design schemes and for operation and maintenance personnel to discover potential fault hazards in advance. At the application service level, the existing transmission line design and operation and maintenance platforms have single functions and lack coordination, making it difficult to achieve efficient information sharing and collaboration among designers, constructors, and operation and maintenance personnel. At the same time, due to the lack of effective training and education tools, the professional skills and emergency handling capabilities of relevant personnel are difficult to be rapidly improved, further increasing the cost and risk of transmission line construction and operation and maintenance and reducing the reliability of power supply. Summary of the Invention

[0003] The purpose of the present invention is to provide a three-dimensional precise modeling system and method for high-altitude transmission lines, aiming to solve the problems that in terms of data processing, the previously collected geographical information, meteorological data, and transmission line parameters are often independent of each other, lacking effective integration and analysis, and unable to explore the potential connections between data to provide comprehensive support for the design of transmission lines. In addition, the accuracy of traditional transmission line modeling technology is relatively low. The tower and conductor models cannot truly reflect their actual shapes and mechanical properties in complex environments, and the scene model also lacks dynamic simulation of geographical and meteorological elements, making it difficult for designers to intuitively evaluate the rationality of design schemes and for operation and maintenance personnel to discover potential fault hazards in advance.
