Description

Technical Field

[0001] The present invention belongs to the technical field of line planning, and in particular relates to a method, device, equipment and medium for planning a path of a power grid line. Background Art

[0002] Transmission lines are an important part of the power system, and their planning and design play a vital role in the normal operation of the power system and power supply. Transmission line planning mainly includes field surveys, line selection calculations, engineering economic analysis and environmental assessment. In the process of line planning, it is also necessary to fully consider factors such as power load, power supply range, voltage level, transmission distance, topography, environmental protection, etc., in order to select the best transmission line direction and structure, and pay attention to safety, economy and environmental protection.

[0003] There are many factors that need to be considered in the planning of transmission lines. Its accuracy and feasibility will directly determine the difficulty of preparing the subsequent feasibility study plan and engineering construction. Traditional line planning has scattered data, incomplete "multi-plan integration" data, a long field survey process, incomplete site selection and line selection dimensions, and some line planning schemes meet urban and rural planning but not land regulations, or meet planning but fail to avoid ecological red line areas and areas prone to geological disasters. It is even impossible to complete the demolition due to the large number of existing above-ground and underground objects, resulting in slow or even impossible construction of subsequent projects. Summary of the invention

[0004] The object of the present invention is to provide a method, device, equipment and medium for planning a path of a power grid line, so as to solve the technical problem of low accuracy of existing path planning methods.

[0018] Determine the starting point coordinates and the end point coordinates according to the preset path;

[0019] Generate a judgment result based on the starting point coordinates, the end point coordinates and the vertex coordinates;

[0020] If the result of the first judgment is crossing, a second judgment is performed;

[0021] If the result of the first judgment is that it is not crossed, the planning layer and the preset path will be output without a second judgment;

[0022] If the secondary judgment result is crossing, the crossing part of the preset path will be highlighted and the planning layer and the marked preset path will be output;

[0023] If the secondary judgment result is not crossed, the planning layer and preset path are output.
