Referring to fig. 1, the method mainly includes the following steps:

s101, acquiring a plane layout of a factory to be built;

obtaining a CAD layout of a factory to be built, and exporting the CAD layout into a PDF format file through AutoCAD; and opening the PDF format file by using the Adobe Illustrator, exporting the file into a JPG picture format file, and taking the file as a plane layout of a plant to be built. Opening Cinema4D, loading a JPG plane layout diagram, switching to a top view according to F2, selecting a 'background' menu according to shift + V, adjusting the transparency to 92%, and improving the viewing effect.

S102, identifying and determining a target component in the plane layout, wherein the target component comprises the following objects: equipment, walls and aisles;

in order to facilitate the outline delineation of each target component, the display is adjusted to a line mode.

S103, carrying out line hooking on each target component according to the graphic outer contour of the target component to form a closed sample line;

and opening the 'starting capture-vertex capture' function, and drawing lines along the equipment outline, the wall and the factory passageway in the drawing by using a sample line drawing tool to finally form a closed sample line.

Aiming at the fact that a connecting line between two adjacent vertexes of the outline of the graph and a plane rectangular coordinate system form a non-parallel or non-90-degree relation, the connecting line is used as a hypotenuse of a right triangle, the two adjacent vertexes are connected through the other two rectangular sides of the right triangle, and the right triangle is located outside the outline of the graph of the target component; see the device outline as shown in fig. 2.

Aiming at the condition that the outline of the graph is a curve, lines which are parallel/vertical to the plane rectangular coordinate system and tangent to the outline curve are used for hooking; see the device outline as shown in fig. 3. So that the resulting closed spline is a regular right-angled polygon. Therefore, the complexity of the three-dimensional model can be reduced, and the visual viewing effect is not influenced.

S104, setting the height of a Y axis by taking the closed sample line as an X axis Z axis plane to generate a three-dimensional object model;

switching to a perspective view according to F1 in Cinema4D, selecting a drawn closed sample line, pressing an Alt key to click an extrusion button, setting the height to be extruded on a Y axis, and setting the heights of an X axis and a Z axis to be 0, so that a three-dimensional model is formed by extrusion, wherein the built model has the characteristics of high appearance identification and high modeling speed; and in the same way, other equipment, walls and passageways are all extruded into the model.

In order to facilitate visual distinguishing and displaying of three types of components including equipment, walls and passageways, three glass balls with different transparencies can be newly built, the high transparencies are endowed to the passageways, the middle transparencies are endowed to the walls, and the low transparencies are endowed to the equipment.

Wherein, the equipment models are numbered according to S-0001, S-0002 and S-000N rules (N is a variable), and names are put into a model library. In future projects, similar equipment can be directly dragged to use, and the modeling efficiency is improved. Hardware data of the factory equipment can be uploaded by the management background and stored in the database in an excel mode for association.

In order to make the three-dimensional modeling effect more fit with the actual layout of a factory and better restore the actual layout scene of the factory, in the embodiment, the three-dimensional object models of all production equipment are set to be made of glass materials, and the three-dimensional object models of walls and passageways are set to be made of diffuse reflection materials, so that the difference of the production equipment and other components in the display effect is highlighted; the wall body is brick concrete usually, and the passageway is the resin rubber material usually, consequently will correspond the three-dimensional model and set up to the diffuse reflection material, accords with actual visual effect more.

Aiming at production equipment, a plurality of different using states are usually provided, in order to directly realize the visual presentation of the equipment state, when a three-dimensional object model has N states, N glass materials with different colors are established for the three-dimensional object model, and the glass material with each color only corresponds to one state; wherein the N states include a normal state, a fault state, and a deactivated state.

For example, aiming at the three states of normal, fault and halt of the equipment model S-0001 in the daily production process, the equipment model can be established to be made of red glass, green glass and yellow glass; when the equipment is in a fault state, calling a red glass material; the equipment is in a shutdown state, and a yellow glass material is called; the equipment is in a normal state, and green glass materials are called; this information is stored in a database in preparation for subsequent model use procedure calls. If only the glass material of a colour, when the equipment state changes, can't correspond and distinguish through the colour demonstration, be not convenient for enterprise manager directly perceived, conveniently master current mill equipment production condition. When the equipment is in a fault state, the equipment model turns red, and a manager is prompted to pay attention to the equipment model; when the equipment normally operates, the equipment model is displayed to be green; when the equipment is in standby, the equipment displays yellow; clicking equipment in a factory, comparing ID numbers in a database, finding out equipment data and production data bound by the ID, and presenting the information in a bullet layer form; clicking the equipment again, enabling the elastic layer to disappear, and enabling the factory to recover the default visual angle; the equipment model can also bind production data and quality data through the ID number, and the life cycle of the equipment can be comprehensively monitored. The manager can see the red equipment model through a graphical interface, click and check equipment information, quickly inform workers of going to process, change the equipment fault into green again when the equipment fault is solved, and operate normally; the conditions of factory equipment are mastered and processed in real time and rapidly, and the production is ensured to be carried out safely and stably.

Production data generated in the equipment upgrading production process can also be correlated, including but not limited to start-up time, shut-down time, operators, machined parts, current part machining quantity, and current part abnormal quantity; to aid in statistical analysis of data and maintenance of equipment.
