[0056] Further, step S110 further includes:

[0057] The three-dimensional clearance basic information of the target airport includes airport completion materials;

[0058] The airport completion materials include airport completion drawings. For example, in a certain airport project, according to the completion drawings, it can be known that the general layout of the airport, the flight area rating is 4C, the runway is 2,800 meters long and 45 meters wide, and the current elevation of the site is 1,670 - 1,890 m;

[0059] Further, step S120 further includes:

[0060] Using Civil 3D software, establish a three-dimensional terrain surface through the airport's current topographic survey data;

[0061] By analyzing the airport completion materials, it is determined that the flight area rating is 4C and it is a Class I precision approach runway. Then, the parameters of the airport clearance model can be determined, and the airport clearance model is established based on the parameters of the airport clearance model;

[0062] Refer to Figure 2 , the airport clearance model includes an inner horizontal plane, a conical surface, an approach surface, an inner approach surface, a transition surface, an inner transition surface, and a missed approach surface;

[0063] Refer to Table 1.

[0066]

[0067] Further, step S130 further includes:

[0068] The available area of the airport clearance restricted surface of the target airport includes at least the allowable height margin level of the available area and part of the over-clearance area;

[0069] Through the superposition analysis of the three-dimensional terrain surface and the airport clearance model, the allowable height margin levels of the available areas are clustered and divided, including at least the non-clearance area: the allowable height margin is greater than the photovoltaic panel layout height; the partial clearance area: the allowable height margin is greater than or equal to 0 and less than or equal to the photovoltaic panel layout height; the clearance area: the allowable height margin is less than 0.

[0070] Refer to Figure 3 , the schematic diagram of the allowable height margin levels of the available areas for airport photovoltaic in the embodiment, where the left green area is the non-clearance area; the middle yellow area is the partial clearance area; the right red area is the clearance area.

[0071] Optimize the design of the partial clearance area, including the optimization design of photovoltaic equipment components and the adjustment of site leveling.

[0072] Furthermore, step S140 further includes:

[0073] Determining the photovoltaic facility design plan includes determining the plane coordinates, azimuth angle, and installation inclination angle of the photovoltaic facility;

[0074] Calculating the volume of earthwork filling and excavation is to optimize the site leveling plan according to the site leveling adjustment plan, following the design principle of local filling and global excavation, dynamically calculate the earthwork volume, and determine a reasonable plan for the earthwork filling and excavation project volume.

[0075] The dynamic calculation is the Boolean operation between three-dimensional space surfaces.

[0076] Among them, in this embodiment project, considering factors such as lighting, land use conditions, glare, and electromagnetic, the photovoltaic array is arranged. The slope of the cut slope of the airport is about 30° - 40°. The photovoltaic brackets on the cut slope are arranged along the slope to reduce the occupied clearance height. Refer to Table 2, according to the distribution of the cut slope and the fill slope, adjust the parameters such as the plane coordinates, azimuth angle, and installation inclination angle of the photovoltaic facility, and arrange the photovoltaic array along the non-clearance area and the partial clearance area.

[0078]

[0079]

[0080] In this project, considering factors such as investment, following the design principle of local filling and global excavation, continuously optimize the site leveling plan, refer to Table 3, dynamically calculate the earthwork volume, and finally determine a reasonable plan for the earthwork filling and excavation project volume.

[0088] The clearanced area refers to the area where the allowable height margin is less than 0;

[0089] The non-clearance area is used as the available area for the airport clearance limit surface;

[0090] The partially clearanced area is used as the available area for the airport clearance limit surface after optimization design of the partially clearanced area.

[0091] Furthermore, the optimization design of the photovoltaic equipment components further includes:

[0092] By using azimuth adjustment, reducing the inclination angle, translating the plane position, or local excavation, the maximum height of the photovoltaic facility from the ground (such as 2.5 m) is made less than the clearance allowable height of 3.5 m;

[0093] The clearance allowable height is the difference between the clearance surface height and the current terrain surface height. For example, if the clearance surface height is 1741 m and the current terrain surface height is 1737.5 m, then the clearance allowable height is 3.5 m.

[0094] The site leveling adjustment is to level and slope the site for the over-height situation in the partially clearanced area, that is, to reduce the maximum height of the photovoltaic facility from the ground below the clearance allowable height.

[0095] Refer to Figure 4 , which is a schematic diagram of the position of the partially clearanced area.

[0096] Furthermore, when outputting the three-dimensional visualization display diagram of the airport photovoltaic design of the target airport, the adjusted model is integrated using the Unreal Engine and Infraworks platforms, and the relative position relationship between the clearance surface and the photovoltaic equipment is judged three-dimensionally for subsequent simulation deduction and digital delivery of the design results.
