Description

Technical Field

[0001] The invention relates to the technical field of power transmission, and is a three-dimensional design method, terminal equipment and storage medium for a power transmission line construction and transportation scheme suitable for mountainous areas. Background Art

[0002] The transportation plan for power transmission line construction includes design contents such as transportation mode selection, route planning, passability verification, engineering quantity calculation statistics, data comparison and transportation plan demonstration. In the past, there was no relevant and effective three-dimensional design method. In engineering, most of the transportation plans were determined by searching on the map and combining on-site surveys. For mountainous areas, this mode is time-consuming and inefficient.

[0003] For example, Xinjiang Uygur Autonomous Region is located in northwest China, in the hinterland of Eurasia. Its topographical features can be summarized as "three mountains and two basins", namely the Altai Mountains in the north, the Kunlun Mountains in the south, and the Tianshan Mountains running through the middle, dividing Xinjiang Uygur Autonomous Region into north and south. This topography not only shapes the unique natural landscape of Xinjiang Uygur Autonomous Region, but also has a certain impact on the local transportation development. Xinjiang Uygur Autonomous Region has a vast territory, and the transportation of construction materials for power transmission lines must be combined with the topographical characteristics of the area through which the route plan passes.

[0004] Therefore, in order to complete the calculation and analysis of the construction and transportation scheme more quickly and efficiently, a three-dimensional design method for the construction and transportation scheme of transmission lines in mountainous areas is proposed to solve the above problems. Summary of the invention

[0005] The present invention provides a three-dimensional design method, terminal equipment and storage medium for power transmission line construction and transportation schemes suitable for mountainous areas, which overcomes the deficiencies of the above-mentioned prior art and can effectively solve the problem of long time consumption and low efficiency in determining power transmission line construction and transportation schemes in mountainous areas.
