Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Nothing in the following detailed description is intended to indicate that any particular component, feature, or step is essential to the application. Those of skill in the art will understand that various features or steps may be substituted for or combined with one another without departing from the scope of the disclosure.
FIG. 1 illustrates a flow chart of a method of loading chemical industry nonstandard equipment based on 3D modeling in accordance with an exemplary embodiment of the present disclosure. The disclosure provides a method for loading chemical industry nonstandard equipment based on 3D modeling, which comprises the following steps: S1-S6. Specifically, the method may include S1. At S1, a 3D model library of related vehicles of the transporter may be established. Fig. 2 shows a schematic diagram of a 3D model of a related vehicle according to an exemplary embodiment of the present disclosure. Specifically, information of the transporter and its related vehicles can be added and deleted according to the authority. For example, a library of vehicle models may be drawn and built by a third party software platform, and then models of the vehicles are categorized according to the attributes of different types of vehicles (e.g., length, width, height, load limits, etc.). In other embodiments, models of vehicles may also be categorized according to any other attribute deemed appropriate by those skilled in the art.
The method may further comprise S2. And S2, searching for a matched vehicle in the 3D model library according to the parameters of the chemical non-standard equipment. For example, suitable vehicles may be automatically matched for screening and providing a preview of the vehicle model. In a preferred embodiment, S2 may further include: after finding a matching vehicle in the 3D model library, information of the matching vehicle may be pushed to the transporter. In a preferred embodiment, in S2, the parameters of the chemical non-standard equipment may include the diameter, weight, length and pre-weld location of the chemical non-standard equipment, or any other parameters deemed necessary by those skilled in the art to be needed for loading.
The method may further comprise S3. At S3, 3D modeling may be performed on the chemical non-standard device to obtain a 3D model of the chemical non-standard device, and then light-weight processing may be performed on the model of the chemical non-standard device. In a preferred embodiment, S3 may further include: s31, converting the format of the 3D model of the chemical non-standard equipment into OBJ, FBX and STL format files; s32, other surfaces except the outline can be subtracted under the condition that the outline of the 3D model is reserved; and S33, reconstructing the contour of the 3D model. For example, the face-subtracting process may be performed with the original structure left and the original structure not left. In addition, the original model can be lightened, the method is suitable for a multi-terminal display, interaction and editing driving drawing model, and the method can automatically perform surface reduction, UV display (the UV display information is stored in the UV channel 2 for AO processing) and thumbnail derivation processing. In addition, topology light weight can be carried out, the method is suitable for a multi-terminal display, interaction and editing ultra-large magnitude model, a complete contour reconstruction new model is reserved for an original model based on a bottom layer algorithm, texture merging and compression are carried out under the condition that an original structure is not reserved, and color mapping, normal mapping and AO mapping can be output. In addition, the oblique photography is light, is suitable for oblique photography models with multi-terminal display, interaction and editing, can automatically cut the model into multi-block multi-level models, and performs operations such as automatic face reduction, automatic UV unfolding, full-field baking, texture compression and merging on the model based on the three-dimensional model appearance of the oblique photography live-action; and realizing the precision loading of different blocks and different levels of the model according to the automatic identification of human eyes. After the light-weight operation, the occupied volume of the model can be further reduced, and meanwhile, the operation speed of carrying out the 3D model interference inspection in the loading process is also increased.
The method may further include S4. At S4, a tool for loading may be designed based on the matched vehicle model and the 3D model of the chemical non-standard equipment. The method may further comprise S5. At S5, an interference check is performed on the tooling designed for loading. Fig. 3 illustrates a schematic diagram of collisions and interference that may occur with tool and chemical non-standard equipment according to an exemplary embodiment of the present disclosure. In a preferred embodiment, in S5, collision and interference that may be generated by the vehicle, the tool, and the chemical non-standard equipment during transportation of the chemical non-standard equipment may be simulated, and states of the vehicle, the tool, and the chemical non-standard equipment may be determined. For example, a fixed branch may make tooling for equipment loading according to a process notice prior to the delivery order being placed, e.g., requiring the loading to be completed the day prior to loading. Then, the manufacturing of the tool can be determined according to the design drawing of the equipment; and according to the size, tonnage and pre-welding position of the equipment, performing interference check on the designed three-dimensional model of the tool and the equipment for loading, and showing the interference position among the vehicle, the tool and the chemical non-standard equipment. The interferometry can be divided into static interferometry and dynamic interferometry. The static interference can simulate the interference relation between a vehicle flat plate and workpieces such as equipment, tools and the like in the loading process. Dynamic interference can simulate collisions and interference that may occur during the loading motion. The interference gap can be preset by using three-dimensional software, and if the gap between the workpieces is smaller than the preset size of the interference gap, the interference result is highlighted. Further, the states of equipment, tools and a vehicle panel can be judged through interference inspection, and the effect of simulating loading is achieved so as to shorten loading time. The types of interference can be roughly classified into 5-clock types: 1) No interference: the distance between 2 workpieces is larger than the gap area; 2) Contact interference: the two workpieces are in contact with each other but do not interfere, and the system gives a point representing contact interference; 3) Hard interference: the two workpieces are intersected, a common part exists, and the system establishes an interference entity; 4) Soft interference: the minimum distance is smaller than the gap area, but is not contacted, and the system represents the minimum distance by a line; 5) And (3) interference is contained: the system may create a copy that identifies the interfering enclosed entity.
The method may further include S6. At S6, for example, after the completion of the interference check, a 3D loading model of the chemical non-standard equipment, that is, a 3D model of the chemical non-standard equipment mounted on the vehicle by the tooling, may be constructed according to the matched vehicle, the designed tooling for loading, and the 3D model of the chemical non-standard equipment. In a further preferred embodiment, in S6, the stack of vehicles, i.e. the outer contour of the vehicle when the chemical non-standard device is installed, can be automatically planned as a function of the information of the matched vehicle. In a preferred embodiment, the method may further comprise S7. At S7, a loading angle and orientation may be determined from the constructed 3D loading model. In a preferred embodiment, the method may further comprise S8. At S8, the loading process of the chemical non-standard equipment may be simulated multiple times according to the determined loading angle and azimuth, and a 3D animation of the loading process may be drawn.
Compared with the prior art, the beneficial effects of the present disclosure are: the invention solves the problems that the matching degree of equipment and a car cannot be perceived in advance and collision possibly occurs in the loading process of chemical non-standard equipment and the like through 3D modeling. By adopting the 3D modeling technology and the interference model, multiple simulation can be performed before loading, and the most suitable vehicle type, loading angle and mode are selected. Meanwhile, the model size of the 3D model in the loading simulation process is further reduced through various lightweight model modes, the problems that the model is too large to cause clamping and cannot be simulated accurately and the like are solved, and therefore loading adaptation and loading speed of chemical non-standard equipment are improved, and transportation cost of the chemical non-standard equipment is effectively saved.
