[0046] Example 1

[0047] In this embodiment, a method for reconstruction and expansion of overhead transmission lines in a three-dimensional model scenario is disclosed, such as Figure 1 As shown, including:

[0048] Obtain the tower account information of renovation and expansion;

[0049] Extract the line name and tower code from the tower record information of the reconstruction and expansion;

[0050] According to the line name, extract the line ledger information, wherein the line ledger information includes the tower ledger information of all towers in the line, and each tower ledger information includes the tower code, tower type, hanging point information and tower posture information;

[0051] According to the tower code, the tower account information of the reconstruction and expansion is added to the tower account information of the extracted line account information corresponding to the tower code, so as to form the reconstruction and expansion line account information;

[0052] Based on the inventory information of the modified and expanded line, a three-dimensional model of the modified and expanded line is generated.

[0053] Before constructing the three-dimensional model of the line after reconstruction and expansion, this embodiment first builds a transmission line model library, in which various types of tower models, ground wire string models, line ledger information of each line and three-dimensional models of each line are stored, wherein the ground wire string includes insulators and conductors.

[0054] This embodiment also retrieves the three-dimensional model of the original line according to the line name;

[0055] The 3D model of the original line and the 3D model of the line after reconstruction and expansion are displayed synchronously, so that the original line and the line after reconstruction and expansion can be compared intuitively.

[0056] The hanging point information includes the relative coordinates of the tower head hanging point, the overall coordinates of the tower and the nominal height of the tower.

[0057] The line inventory information includes the line name and the tower inventory information of all the towers in the line. The inventory information of each tower includes the tower code, the line name, the tower type, the voltage level, the tower type, the hanging point information, the number of loops, the city, the line arrangement, the phase sequence / pole, whether it is the same pole, the tower model and the tower posture information. Among them, the hanging point information includes the relative coordinates of the tower head hanging point, the overall coordinates of the tower and the tower nominal height, etc. The posture information includes the position information and attitude information. The position information can be reflected in the coordinates.

[0058] The three-dimensional models and line inventory information of each line stored in the database are retrieved using the line name as the index.

[0059] The three-dimensional models of each line stored in the database are three-dimensional models of the original lines before the lines are modified or expanded.

[0060] When it is necessary to renovate or expand a pole tower on a certain line, first generate the tower inventory information based on the tower code, the line name of the tower, the tower position information, the tower type and hanging point information.

[0061] When a three-dimensional model is to be displayed for the line after reconstruction and expansion, the inventory information of the reconstruction and expansion tower is obtained, and the line name, tower code, tower position information and hanging point information in the inventory information of the reconstruction and expansion tower are extracted.

[0062] According to the line name, extract the line account information corresponding to the line name and the three-dimensional model of the original line corresponding to the line name;

[0063] According to the tower code, the tower account information of the reconstruction and expansion is added to the tower account information of the extracted line account information corresponding to the tower code, so as to form the reconstruction and expansion line account information;

[0064] Generate a 3D model of the line after reconstruction and expansion based on the account information of the line to be reconstructed and expanded;

[0065] like Figure 2 As shown, the three-dimensional model of the original line and the three-dimensional model of the line after reconstruction and expansion are displayed synchronously.

[0066] The process of generating the three-dimensional model of the line after reconstruction and expansion in this embodiment is as follows:

[0067] Extract the tower type, hanging point information and tower position information from the tower record information;

[0068] Determine the tower model and hanging point information according to the tower type;

[0069] Determine the ground wire string model and ground wire string posture information according to the tower model and hanging point information;

[0070] Determine the posture information of the ground wire string model and the posture information of the tower model according to the posture information of the ground wire string and the posture information of the tower;

[0071] A three-dimensional model of the corresponding line is generated according to the posture information of the ground conductor string model, the posture information of the pole tower model, the pole tower model and the ground conductor string model.

[0072] Specifically, the terrain information where the tower is located is determined according to the tower posture information;

[0073] According to the terrain information of the tower, the tower posture information and the ground wire string posture information, the posture information of the ground wire string model and the tower model are determined.

[0074] According to the posture information of the tower model, the ground wire is constructed in vector form to obtain the basic form of the line, and the attribute information is stored in the database to realize the construction of the graph attribute query capability of the tower group equipment;

[0075] The pole tower model and the ground conductor string model are retrieved, and according to the posture information of the ground conductor string model and the pole tower model, the pole tower model, the ground conductor string model and the basic form of the line are spliced ​​to form a three-dimensional model of the line.

[0076] The process of determining the ground wire string model in this embodiment includes:

[0077] Extract the tower model, tower position information, voltage level and tower type from the tower record information;

[0078] Determine the tower model and hanging point information according to the tower model and tower type;

[0079] The ground wire string model is determined according to the voltage level and the connection method of the ground wire string between adjacent towers.

[0080] In this embodiment, different colors are used to render different phase lines of the tower and the ground conductor in the three-dimensional model.

[0081] This embodiment draws the ground wire vector in a three-dimensional scene according to the endpoint position, key point position and other data of the ground wire, uses yellow, green, red and gray to render and color the tower and the ground wire phase A, phase B and phase C, organizes and stores the drawing results in the format of vector data, and publishes them as data services that can be loaded on the three-dimensional platform.

[0082] The present embodiment discloses a method for reconstruction and expansion of overhead transmission lines in a three-dimensional model scenario, in which a line name and a tower code are set in the tower ledger information, and the line where the tower to be reconstructed and expanded is located can be determined according to the line name, and then the line ledger information of the line can be extracted, wherein the line ledger information includes the tower ledger information of each tower in the line; thereafter, the tower to be reconstructed and expanded is determined according to the tower code, and the tower ledger information of the reconstructed and expanded tower is added to the line ledger information as the tower ledger information of the reconstructed and expanded tower; the ledger information of the reconstructed and expanded line is formed; and the three-dimensional model of the reconstructed and expanded line is generated using the reconstructed and expanded line ledger information, thereby realizing the rapid generation of the three-dimensional model of the reconstructed and expanded line.

[0083] This embodiment can also synchronously load and display the three-dimensional model of the line after reconstruction and expansion and the three-dimensional model of the original line before reconstruction and expansion, and at the same time analogize the direction of the original line, effectively conduct on-site investigation and deductive analysis of the construction work, and realize the precise and rapid construction of the three-dimensional grid of overhead transmission lines in various scenarios.

[0084] The method disclosed in this embodiment can construct the functions of deduction scheme backtracking and scheme exporting, edit the deduction analysis report of the overall situation of the reconstruction and expansion in the form of pictures and text, support the execution of line reconstruction and expansion business, carry out reconstruction and expansion construction site survey, line reconstruction and expansion process deduction, line reconstruction and expansion deduction backtracking and scheme generation.

[0085] This embodiment has a small amount of modeling work, and only needs to model each model in the model library. After the model in the model library is released, it can be repeatedly called to support the construction of the three-dimensional model of the line; and the line adopts a parametric construction method for three-dimensional construction. After obtaining the line ledger information, after parameter calculation, the three-dimensional construction, rendering display, ledger hanging and other functions of the line can be quickly realized in a short time. Loading is efficient and stable. Since the pole tower and ground wire string of the line are loaded by model, and the ground wire is drawn by vector line drawing, the three-dimensional platform can more flexibly adopt relevant scheduling mechanisms to ensure efficient and stable loading of a large number of overhead line three-dimensional model data.
