2. The distribution primitive three-dimensional model library, as shown in fig. 2, displays various distribution primitives on a screen. The manufacturing method of the power distribution primitive three-dimensional model comprises the following steps:
(1) distribution primitive equipment photo material collection
The photo material of the distribution primitive equipment is the first step of manufacturing a three-dimensional model of the distribution primitive equipment, and the real distribution primitive equipment is known firstly when a real and detailed three-dimensional model is manufactured, and the process is finished through the field material drawing work.
(2) Power distribution primitive equipment information data collection
The equipment nameplate information of each power distribution primitive needs to be carefully collected, which provides an important basis for equipment type selection in the scheme design in the future.
(3) Power distribution primitive three-dimensional model production
As shown in fig. 1, a model resource of an FBX file is created using Maya modeling software based on photographed photo material and related information material.
(4) Distribution primitive three-dimensional model import
Because the FBX file directly exported after the model is manufactured by Maya is often large, large hard disk resources are occupied when a large batch of power distribution primitive three-dimensional models are manufactured, but model packaging and compression can be carried out by using a packaging plug-in independently developed by a Unity3d engine to form a model resource package, so that the hard disk space occupied by the three-dimensional model is greatly reduced, and the loading speed of the power distribution primitive three-dimensional model is further accelerated.
(5) Power distribution primitive equipment information entry
The distribution primitive equipment information comprises information such as an equipment three-dimensional model path, a thumbnail, an equipment model, a manufacturer and related parameters, and is manually input into a system database through a background management page.
With the equipment information data, a user can check the contents of the three-dimensional model, the equipment model, the parameters and the like of the currently selected power distribution primitive at any time when designing a power distribution scheme, and meanwhile, the user can design more reasonably and more efficiently.
(6) Distribution primitive three-dimensional model display and setting
How to accurately and completely fuse the manufactured power distribution primitive three-dimensional model into the three-dimensional geographic information display platform needs to perform relevant setting on each power distribution primitive three-dimensional model. The model settings include model coordinate center, physical impact zone, relative size correction settings.
The model coordinate center refers to the degree of displacement of the three-dimensional model with respect to its three-dimensional coordinates.
And the physical collision area defines a physical area occupied by the three-dimensional model, so that the interpenetration of personnel and a wall body is prevented.
The relative size correction method is that the three-dimensional model can be corrected to the real size through the relative size due to the relation of a scale in the manufacturing process.
(7) Distribution primitive three-dimensional model library
As shown in fig. 2, all the power distribution primitives are uniformly integrated and classified to form a power distribution primitive three-dimensional model library, which is convenient for users to check and use.
3. Power distribution primitive visual arrangement module
The step of visually arranging the power distribution primitives in the three-dimensional geographic information display platform comprises the following steps:

The moving and placing of the three-dimensional distribution graphic primitive equipment in the distribution line scheme design are the basis for realizing the whole scheme, and a user can freely select a distribution graphic primitive to be added through a mouse and drag the distribution graphic primitive to a specified position of the three-dimensional geographic information display platform.
(3) Three-dimensional model physical collision zone detection
The three-dimensional model physical collision area detection mainly has two aspects, namely, the direct physical collision detection between the virtual character and the three-dimensional model when the first person roams is used for preventing the character from penetrating through a mountain, a wall surface, equipment and the like. On the other hand, when the three-dimensional model of the power distribution primitive equipment is subjected to visual mobile control, the power distribution primitive equipment is prevented from being overlapped and inserted with the ground, the wall surface and other equipment.
(4) Distribution line design template referencing and adding
Distribution line scheme design often involves a wider range, and many similar schemes often have more common points. The distribution line design template is a standard template formed by integrating several types of distribution line typical schemes and is used for reference of designers.
The designer can select distribution lines design template to introduce as required before designing the distribution lines, and the designer can quickly complete the design only by modifying and arranging the template on the basis of the template after the template is introduced.
(5) Distribution line design information storage and reading
After the distribution line scheme is designed by a user, data can be stored in the database at any time, and the designed distribution line scheme can be checked and retrieved at any time and read and modified.
(6) Distribution line design information evaluation mode
After logging in, the review user can check the condition along the line, compare and select multiple schemes, check the equipment type selection condition, check the reasonability of a corridor along the line, and safely distance from a building to the existing design scheme, and meanwhile, comments can be added to any position of the design scheme at any time in the review process.

Meanwhile, the user can control the person to freely roam in the three-dimensional geographic information display platform by himself.
(2) Visual browsing and inquiring of power distribution graphics primitives
The selection of the power distribution graphic elements in the scheme design of each power distribution line is usually based on the appearance, model and related parameters of the power distribution graphic element equipment. When a designer selects a power distribution primitive, the system automatically displays a three-dimensional model preview of the primitive, and provides detailed parameter description. The designer can also screen the distribution primitives by name, category, model, parameter range, etc.
