Obviously, the drawings in the following description are only preferred embodiments of the present application, and other drawings can also be obtained by those skilled in the art without any creative effort on the basis of these drawings.

[0026] Figure 1 is a schematic diagram of the overall process of the photovoltaic support building construction simulation method provided by the embodiments of the present application.

[0027] Figure 2 is a schematic diagram of the process of selecting the position of the bored pile provided by the embodiments of the present application. DETAILED DESCRIPTION

[0028] The principles and characteristics of the present application will be described below in combination with the drawings, and the listed embodiments are only used to explain the present application and not to limit the scope of the present application.

[0029] Reference Figure 1The embodiment provides a photovoltaic support construction simulation method, and the method comprises the following steps:

[0030] S101, target position information is acquired, and target position topographic information is searched based on the target position information.

[0031] The target position information is target position information input by a user for preparing to build a photovoltaic support, and the target position topographic information comprises information such as topography and geology of the target position, and specifically can comprise information such as topography, soil type and underground water resource distribution. The target position topographic information can be searched based on specific longitude and latitude information of the target position through a related database and / or the Internet.

[0032] S102, a target position simulation topographic map is displayed in a visual interface based on the target position topographic information. The target position simulation topographic map can clearly show the undulating state of various fixed objects distributed on the ground surface of the target position, and the user can view the target position simulation topographic map from various angles through the visual interface.

[0033] S103, drilling pile preset position information selected in the target position simulation topographic map is acquired, and photovoltaic support selection information is acquired, and a corresponding photovoltaic support construction effect schematic model is generated in the target position simulation topographic map based on the drilling pile preset position information and the photovoltaic support selection information. The drilling pile is used as a photovoltaic support foundation to install and support the support and the solar cell assembly, the user can directly select the specific position of the drilling pile in the target position simulation topographic map according to a construction scheme, and select the type of the photovoltaic support installed on the drilling pile, and it can be understood that the types of the photovoltaic supports installed on different drilling piles can be different. After the user selects the drilling pile preset position and selects the type of the photovoltaic support, the system generates a drilling pile graph in the corresponding position of the target position simulation topographic map, and adds a photovoltaic support graph of a specified type on the drilling pile graph, so that the construction effect of the photovoltaic support is intuitively displayed, and the user can judge whether the final construction effect meets the expectation.

[0034] S104, feasibility analysis is performed based on the target position topographic information, the drilling pile preset position information and the photovoltaic support selection information, and a photovoltaic support construction simulation analysis report is output based on the feasibility analysis result. The user can view the photovoltaic support construction simulation analysis report through the visual interface, judge whether the current construction scheme has sufficient feasibility according to the report content, and judge what needs to be adjusted, so that the efficiency of the early stage work of the photovoltaic support construction is improved.

[0035] Reference Figure 2As a preferred example, in step S013, the preset position information of the selected bored pile in the target position simulation topographic map is acquired, specifically including the following steps:

[0036] S201, acquiring an initial position of the bored pile in the target position simulation topographic map, and generating a bored pile pattern at the initial position. The initial position of the bored pile in the target position simulation topographic map is the first bored pile position selected by the user in the target position simulation topographic map. When the user selects the first bored pile position, a pattern representing the bored pile appears at the corresponding position in the target position simulation topographic map.

[0037] S202, when the user selects a preset arrangement template, generating a corresponding array of bored pile patterns in the target position simulation topographic map based on the initial position and the preset arrangement template selected by the user. In this embodiment, several preset arrangement templates of the bored pile are provided, such as circular arrangement, square arrangement, etc. The user can select a corresponding preset arrangement template according to needs. When the user selects the preset arrangement template, the system generates an array composed of multiple bored pile patterns in the target position simulation topographic map starting from the initial position of the bored pile according to the preset arrangement template. The user can adjust the number of bored piles in the array, or select the starting position of the starting bored pile.

[0038] S203, when the user selects a custom arrangement, dynamically generating a corresponding preview bored pile pattern based on the operation instruction input by the user after selecting the bored pile pattern at the initial position. In this embodiment, in addition to automatically generating the array of bored piles through the preset arrangement template, the user can also customize the arrangement of the bored piles. Illustratively, the user can set the position of the bored pile in the target position simulation topographic map one by one, or generate a corresponding preview bored pile pattern by inputting a specified operation instruction after selecting the bored pile pattern at the initial position. For example, when the user selects the bored pile pattern at the initial position and inputs an extension instruction, the mouse pointer can be moved away from the bored pile pattern at the initial position. At this time, multiple straight-line arranged bored pile patterns with a transparency of 50% will appear between the mouse pointer and the bored pile pattern at the initial position. When the user further inputs a confirmation instruction, these bored pile patterns will be fixed in the target position simulation topographic map. It can be understood that the operation instruction can also have other forms, such as copying, etc., thereby assisting the user to quickly complete the setting of the bored pile in the target position simulation topographic map.

[0039] In some embodiments, when generating the cast-in-place pile pattern array, the system automatically adjusts the spacing and position of the cast-in-place pile image according to the target location topography information. For areas with more mountainous terrain, due to the large height difference of mountainous terrain itself, some positions may not be able to generate a cast-in-place pile pattern array according to the user's preset cast-in-place pile spacing. At this time, the system will move the cast-in-place pile pattern at the position where the cast-in-place pile cannot be set to the side, thereby achieving adaptive adjustment and avoiding the final photovoltaic support construction scheme from being unable to be applied to actual use.

[0040] As a preferred embodiment, the display device for displaying the visualization interface includes a computer display and a VR head-mounted display. The user can choose to view the 3D target location simulation topography map and photovoltaic support construction effect schematic model presented in 2D pictures through the computer display; or choose to view the simulation scene of the target location through virtual reality, and input instructions such as setting the position, spacing, and setting depth of the cast-in-place pile through the VR handheld controller. Through the VR device, the user can more intuitively understand the actual topography of the target location, thereby making more reasonable planning for the construction of the photovoltaic support.

[0041] As a preferred example, after the system obtains the photovoltaic support selection information, the load and settlement value of the cast-in-place pile are calculated by combining the target location topography information and the cast-in-place pile preset position information (including the size design information and pile cross-sectional area of the cast-in-place pile), and are dynamically displayed in the target location simulation topography map in a visual form. For example, different font colors can be used to prompt whether the load and settlement value of the cast-in-place pile under the current design scheme is reasonable. When the user moves the mouse pointer over a cast-in-place pile pattern, the corresponding load value and settlement value are displayed in the visualization interface. When the load value or settlement value exceeds the reasonable range, the display font color will change to red to prompt the user that the current design is unreasonable and needs to be adjusted. When the load value and settlement value are within the reasonable range, the display font color is green.

[0042] As a preferred example, after generating the photovoltaic support erection effect schematic model, target position historical climate information is obtained based on the erection target position information, and a dynamic day and night animation effect is added to the target position simulated topographic map and the photovoltaic support erection effect schematic model according to the target position historical climate information and the target position topographic information. The target position historical climate information mainly includes the sunrise and sunset time of different seasons at the target position, and the dynamic day and night animation effect mainly adds an animation effect of the photovoltaic support being irradiated by sunlight from different directions at the simulated sunrise and sunset time to the photovoltaic support erection effect schematic model, so that the user can intuitively feel the angle of the photovoltaic support being irradiated at different positions according to the animation effect, so as to adjust the unreasonable design.

[0043] Since the photovoltaic power station needs to occupy a large area, it is easy to involve forestry and agricultural land, resulting in building land expropriation problems and disputes. In order to solve this problem, the embodiment performs feasibility analysis based on the target position topographic information, the bored pile preset position information and the photovoltaic support selection information, which specifically includes: determining the photovoltaic support erection range based on the bored pile preset position information, connecting a land information database, obtaining the type information and the ownership information of the land covered by the photovoltaic support erection range, determining whether the type information and the ownership information meet the preset conditions, and if not, issuing a prompt to change the bored pile position, and highlighting the land plot that does not meet the preset conditions in the target position simulated topographic map. The preset conditions are set by the user in advance to limit the land type and ownership status that meets the user's expectations. For example, the highlighting of the land plot that does not meet the preset conditions can be highlighting the land plot that does not meet the conditions, or adjusting the color of the corresponding land plot to a bright color that is different from other land plots.

[0044] As a preferred example, the feasibility analysis based on the target position topographic information, the bored pile preset position information and the photovoltaic support selection information specifically further includes: analyzing whether the target position land condition can meet the photovoltaic support erection construction based on the target position topographic information; determining whether the daily minimum sunshine time meets the requirements based on the target position topographic information and the bored pile preset position information; and determining whether the adjacent photovoltaic supports are blocked based on the bored pile preset position and the photovoltaic support selection information.

[0045] It can be understood that when one or more contents in the feasibility analysis do not meet the requirements or do not meet the requirements, it indicates that the current photovoltaic support construction scheme does not completely have or have feasibility, and needs to be adjusted again. In order to help users reduce the time and other costs required for re-adjusting the construction scheme, when the feasibility analysis result is not completely or not completely feasible, the embodiment obtains the expected parameters input by the user, finds the alternative construction target position meeting the expected parameters based on the expected parameters around the construction target position, generates the simulation topographic map corresponding to the alternative construction target position, and generates the photovoltaic support construction effect schematic model in the simulation topographic map of the alternative construction target position based on the expected parameters. The expected parameters include daily minimum sunshine time, daily minimum power generation, and maximum number of photovoltaic supports.

[0046] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
