[0025] Figure 1 Disclosed is a method for quickly constructing a pole and tower model according to the present invention, including: separately modeling the pole and tower components required for the pole and tower model to obtain pole and tower component models corresponding to different voltage levels; respectively establishing pole and tower assembly anchor point models for each pole and tower of different voltage levels according to the pole and tower composition structure of different voltage levels and the hanging point positions of the pole and tower components; classifying the established pole and tower component models and pole and tower assembly anchor point models according to the voltage level to obtain multiple classification files for the pole and tower component models and pole and tower assembly anchor point models of different voltage levels, and uploading the multiple classification files to the server; when constructing a pole and tower model, according to the voltage level of the power transmission and distribution line, downloading the pole and tower component models and pole and tower assembly anchor point models of the corresponding voltage level from the classification files in the server, and using the corresponding pole and tower assembly relationship information read and downloaded from the server to assemble the pole and tower component models and pole and tower assembly anchor point models together to form a pole and tower model.

[0026] In an embodiment of the present invention, the pole and tower components of the present invention include a tower frame, a conductor insulator string, a jumper insulator string, an optical cable fitting, and a ground wire fitting. Figure 2 Disclosed is the structure of disassembling a pole and tower into pole and tower components according to the present invention; for a straight tower, the present invention disassembles the pole and tower into: a tower frame, an insulator string, an optical cable fitting, and a conductor fitting; for a tension tower, the present invention disassembles the pole and tower into: a tower frame, a conductor insulator string, a jumper insulator string, an optical cable fitting, and a conductor fitting.

[0027] In the above embodiments, separately modeling the pole and tower components required for the pole and tower model includes: based on the entity photos and equipment drawings, using 3D modeling software to separately model the tower, conductor insulator string, jumper insulator string, optical cable fittings, and ground wire fittings, to obtain a tower model, a conductor insulator string model, a jumper insulator string model, an optical cable fittings model, and a ground wire fittings model.

[0028] In an embodiment of the present invention, assembling the pole and tower component model and the pole and tower assembly anchor point model may be: according to the pole and tower assembly relationship information, installing the tower model onto the pole and tower assembly anchor point model to form a combination of the pole and tower assembly anchor point model and the tower model; then installing the conductor insulator string model, the jumper insulator string model, the optical cable fittings model, and the ground wire fittings model onto the pole and tower assembly anchor point model of the combination. Figure 3 Shows the assembly relationship of the pole and tower model of the present invention, including the pole and tower type name, such as the pole number corresponding to different voltage levels. When assembling the pole and tower model, first determine the pole and tower type name, such as the No. X low-voltage pole, and then determine the angle control parameters, anchor point installation path, component name, and size control parameters corresponding to the No. X low-voltage pole. The angle control parameters generally include: X-axis rotation angle, Y-axis rotation angle, and Z-axis rotation angle; the size control parameters include: X-axis scaling value, Y-axis scaling value, and Z-axis scaling value.

[0029] The present invention can also save in the server the power transmission and distribution line information including the longitude and latitude coordinates, elevation coordinates of the pole and tower, and the pole and tower type, so as to generate a power transmission and distribution line composed of multiple poles and towers with longitude and latitude coordinates and elevation coordinates according to the power transmission and distribution line information. Figure 4 Shows the power transmission and distribution line information of the embodiment of the present invention, including the line name and ID, the longitude and latitude coordinates of the pole and tower, the pole and tower type name, and the insulator phase sequence, etc.

[0030] As an option, the present invention can also import the multiple classification files into the Unity3D software, convert each classification file into a prefab file, obtain a classification file including the prefab model, and upload the obtained classification file including the prefab model to the server.

[0031] The present invention uses the virtual reality development engine tool Unity3D to convert the parts library model into a prefab file (i.e., a Unity3D file), serialize the 3D model, and reusing the prefab in Unit3D can endow the pole and tower component model data with new attributes for repeated reference, so that only relatively small data changes will occur. When assembling the pole and tower model, the construction of the pole and tower model can be completed dynamically and quickly in real time according to the pole and tower assembly relationship in the database, thereby solving the problems of 3D model data redundancy and complicated maintenance, and fully realizing the reuse of pole and tower parts and equipment.

[0032] The present invention can package each prefabricated body file into an AssetBundle resource package and upload it to the server.

[0033] When specifically implementing the present invention, according to the voltage level of the power transmission and distribution line, the corresponding AssetBundle resource package can be downloaded from the server; the tower component model and the tower assembly anchor point model corresponding to the voltage level can be obtained from the AssetBundle resource package.

[0034] In addition, the present invention provides a storage device for storing the method for quickly constructing the above-mentioned tower model that can be executed by a computing device.

[0035] In addition, another important feature of the present invention is to separate the 3D model from the data, which is convenient for later maintenance and management.

[0036] Next, a Figure 5 specific example of using Unity3D to construct a tower model as shown is used to illustrate the present invention in detail. It should be noted that this example is only used to illustrate the present invention and does not limit the present invention.

[0037] Step 1: Further disassemble the tower model structurally into components such as tower frames, conductor insulator strings, jumper insulator strings, optical cable fittings, and earth wire fittings, as Figure 1 shown. According to the entity photos and equipment drawings, only the tower components are separately modeled using 3D modeling software and exported in fbx format, and a corresponding parts library is established according to the corresponding voltage level, that is, after modeling the components such as tower frames and conductor insulator strings, databases of tower frames, conductor insulator strings, etc. corresponding to voltage levels of 500 kV; 220 kV; 110 kV; 35 kV; (20 kV) 10 kV, etc. are established.

[0038] Step 2: According to the composition structure of each level of tower (i.e., the tower ID corresponding to different voltage levels) and the requirements for the hanging point positions of the equipment, use the position coordinates of the empty object to determine the installation position anchor points of each tower component and export them in fbx format.

[0039] Step 3: Classify the fbx models generated in Step 1 and Step 2 according to the voltage level, import them into Unity3D, further convert the parts library models into prefabricated body files, and finally package them into different AssetBundle resource packages according to the voltage level for local or server download and use.

[0040] Step 4: Store the assembly relationships of different tower types, including parameter information such as the name of each component, the installation anchor point path, the rotation angle, and the scaling ratio, in a table of a relational database. As Figure 3As shown

[0041] Step 5: Save the relevant information in the power transmission and distribution line, mainly including the longitude and latitude coordinates, elevation coordinates of each level of tower pole and the corresponding tower pole type, into the table of the relational database. As Figure 4 shown

[0042] Step 6: When adding a new tower pole type or parts library is needed, only need to establish the tower pole position anchor point and the extended parts model, and repeat the above steps 1 to 5 to update the line information, tower pole assembly relationship and resource package file in the database.

[0043] Step 7: Write a C# script. According to the principles of cooperative programs and asynchronous loading, read the power transmission and distribution line information and the assembly relationship information of each level of tower pole (how many parts are composed, the name, parent object path, rotation angle, scaling value, etc. of each part), download the corresponding AssetBundle resource package according to the voltage level of the power transmission and distribution line, use the prefab model of the parts library in the resource package to dynamically assemble into the corresponding type of tower pole model, and finally generate the power transmission and distribution line according to the longitude and latitude coordinates.

[0044] Compared with the prior art, the present invention has the following advantages:

[0045] 1. Each level of tower pole model is composed of a large number of parts. Different types of tower poles may be composed of shared parts, which inevitably causes repeated use of the parts model and increases data redundancy. The present invention adopts the automatic assembly method of the prefab parts library in Unity3D, subdivides the tower pole structure into the smallest assembly unit, makes full use of the repeated reference of the prefab, and only has the advantage of small data changes, realizes the reusability of the parts, and effectively reduces the size of the tower pole model.

[0046] 2. When adding a new tower type or parts in the present invention, only need to create a separate parts model, without constructing a complete tower pole, which greatly improves the modeling efficiency.

[0047] 3. The present invention saves the power transmission and distribution line information and the tower pole assembly relationship in an external relational database, which is convenient for maintenance and management.

[0048] 4. When replacing the tower pole assembly relationship of the line in the present invention, only need to modify the tower pole assembly relationship in the relational database, without other operations, which is convenient and fast, and greatly improves the maintenance efficiency.

[0049] 5. When loading the tower poles of the power transmission and distribution line, only need to download the tower pole model AssetBundle resource package of the current voltage level, realize downloading on demand, and improve the loading efficiency.

[0050] 6. The AssetBundle resource package is a prefab that is the smallest unit of the part library. It uses coroutines and asynchronous loading methods to download quickly and strictly avoid repeated downloads. After the download is completed, the required part prefabs are obtained from the AssetBundle resource package according to the tower assembly relationship, and the target tower is quickly and dynamically assembled.

[0051] Although the present invention has been described in detail above, the present invention is not limited thereto, and those skilled in the art of this technology can make various modifications according to the principle of the present invention. Therefore, all modifications made according to the principle of the present invention should be understood to fall within the protection scope of the present invention.
