Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The cable model construction method provided by the application can be applied to computer equipment integrated with CST simulation software. The CST simulation software is used for performing simulation analysis on a long cable harness and surrounding environments which are formed by various types of wires under real working conditions, and solving the problem of cable harness crosstalk. When CST simulation software is used for simulation analysis of cable crosstalk problems, a CAD base model obtained by modeling the whole 3D environment by CAD software can be imported, a cable 3D topological structure is automatically built according to the CAD base model, and then a cable model is generated and simulation analysis is carried out.
With the rapid development of electronic information technology, a large number of communication cables are required for communication between various electronic products and devices, and the crosstalk problem between the cables directly affects the communication quality, so that the research on crosstalk between the cables is particularly important. With the development of computational electromagnetics, electromagnetic simulation techniques are increasingly applied to various electromagnetic problems including cable crosstalk, so that modeling simulation of cable crosstalk has important significance. When the cable crosstalk problem is researched, CST simulation software can be adopted for simulation analysis, but because most of CST simulation software is applied to the actual cable crosstalk problem, CAD base models are required to be directly imported to replace manual modeling, but at the moment, the imported CAD base models often contain multi-bifurcation wire harness structures, cables at bifurcation positions are disconnected from a main line and do not accord with the actual cable conditions, at the moment, after the cable 3D topological structure is manually built according to the CAD base models, the cable models can be generated and simulated analysis is carried out, and the problem of low modeling efficiency of the cable 3D topological structure exists. Based on this, the following embodiments of the present application provide a cable model building method, which can solve the above technical problems. The embodiments of the present application are specifically described below.
In one embodiment, as shown in fig. 1, a cable model construction method is provided, and the method is applied to a computer device integrated with CST simulation software for illustration, and includes the following steps:
s102, identifying a bifurcation point of the cable in the cable basic model.
The cable basic model refers to a data model generated by 3D modeling of cables and surrounding structures. Wherein, the model can be built by CST simulation software according to the actual conditions of the cable and surrounding structures; other software with the function of constructing the cable base model can be used for modeling, and the established cable base model is imported into CST simulation software, so that the modeling is not limited. For example, CAD software, PSCAD software, ETAP software, and the like may be employed to model the 3D of the cable and surrounding structures, without limitation.
Specifically, the cable basic model may include a cable bundle model with a bifurcation and a cable surrounding structure model, where the cable bundle model includes at least one bifurcation point, after the CST simulation software obtains the cable basic model, a macro command program stored in advance in the CST simulation software for automatically building the cable model may be called, and a macro command window is popped up, and by clicking a cut cable in the macro command window and creating a cable node option, the CST simulation software automatically analyzes the cable basic model, identifies a cable bundle model in the cable basic model, and then identifies a cable intersection point, i.e., a bifurcation point of the cable, in the cable bundle model. Alternatively, the macro command program in the prestored love CST simulation software may be written through a VBA development platform of the CST software itself. The macro window may include, among other things, the cut cable and create cable node option (Trim Curves and Create Cable Nodes), create cable node (Create Cable Bundles) option as shown in fig. 2.
S104, dividing the cable in the cable basic model according to the bifurcation points to obtain a plurality of bifurcation segments, and constructing nodes of each bifurcation segment.
Specifically, after the bifurcation point of the cable is identified, the system cuts the cable according to the bifurcation point of the cable to form a plurality of bifurcation segments, wherein each bifurcation segment after cutting has two endpoints to form a bifurcation segment topological structure diagram of the cable, namely, a node of each bifurcation segment is constructed. For example, a cable branching section topological diagram as shown in fig. 3 may be built for a cut cable, where the cable base model is a cable model with a binary branch port, and the cable base model is divided into three sections, namely, a N1-N2 section, a N2-N3 section, and a N2-N4 section, according to a branching point N2 of the cable. Wherein, the nodes of the N1-N2 line segments are N1 and N2; the nodes of the N2-N3 line segments are N2 and N3; the nodes of the N2-N4 line segments are N2 and N4.
S106, determining a main line node from the nodes.
The main line is a bus cable used for receiving power signals and transmitting the power signals to each branching cable. The main line node is a node of an input end of a bus cable in the cable harness model.
Specifically, after the node of each branching section is constructed, the program automatically pops up a setting interface, wherein the setting interface comprises node labels of all branch nodes, and a user can set the node as a main line node by selecting the node label of the corresponding node on the setting interface; or after each junction node is constructed, setting is directly performed at each node position in the cable junction topological graph, and a user triggers a setting instruction by selecting a node in the topological graph, wherein the setting instruction is to set the selected node as a main line node, and the setting instruction is not limited herein.
S108, generating a cable model according to the main line node and the plurality of branching sections.
Specifically, after the main line node is obtained, a plurality of branching sections can be determined according to the main line node, the line section with the main line node is the main line section, the rest line sections are branch line sections, at the moment, the main line section and the branch line sections can be combined to generate different cable path models, and the corresponding cable section models are imported to the plurality of cable path models to generate different cable models; the method may also be that a corresponding cable section model is led into the main wire section to obtain a main wire section model, a corresponding cable section model is led into each branch wire section to obtain each branching cable section model, and then the main wire section model and each branching cable section model are combined to obtain cable section models of different paths, which is not limited herein.
In the cable model construction method, the branching points of the cables in the cable basic model are identified, the cables in the cable basic model are segmented according to the branching points, a plurality of branching line segments are obtained, nodes of each branching line segment are constructed, a main line node is determined from the nodes, and the cable model is generated according to the main line node and the branching line segments. The process of constructing the cable topological structure according to the cable basic model so as to generate the cable model is automatically carried out through a program, so that the cable topological structure is generated without manually processing the cable basic model, and the efficiency of constructing the cable model is improved.
Having described the cable model construction method in the above embodiment, step S108 in the cable model construction method will be further described in one embodiment, as shown in fig. 4, generating a cable model according to the main line node and the plurality of wire segments, including:
s402, combining the plurality of branching sections according to the main line node to obtain a cable path model.
Wherein, the cable path refers to the path between each node.
Specifically, after the main line node is determined, the main line segment can be further determined in a plurality of branch line segments, and each branch line segment is combined with the main line segment to obtain different cable path models. For example, as shown in fig. 5, A1 is a main line node, and the corresponding main line segment is an A1-A2 line segment, and the branch line segment includes: A2-A3 segment, A3-A4 segment, A2-A5 segment and A3-A6 segment, and the main line segment and the branch line segment are combined to obtain an A1-A2-A3 path, an A1-A2-A5 path, an A1-A2-A3-A6 path and an A1-A2-A3-A4 path.
S404, generating a cable model according to the cable path model.
Specifically, generating the cable model from the cable path model means that after different cable path models are generated, the corresponding cable section model is imported into each cable path model to generate the cable model. The cable section model refers to a cable section model stored in advance in CST simulation software.
In this embodiment, a cable path model is obtained by combining a plurality of branch segments according to a main line node, and the cable model is generated according to the cable path model. Because the multiple branching segments are combined according to the main line node, different cable path models can be obtained, and an accurate cable model can be built according to the different cable path models.
In the above embodiment, when the cable model is obtained by combining the plurality of branch segments according to the main line node, it is necessary to determine the cable path model first, and then determine the cable model according to the cable path model, and how to determine the cable path model is further described with an embodiment, in one embodiment, as shown in fig. 6, the cable path model is obtained by combining the plurality of branch segments according to the main line node, which includes:
s602, determining a main line segment and a branch line segment from a plurality of branch line segments according to the main line node.
The main line segment refers to a line segment including a main line node. The branch line segment refers to all line segments except the main line segment in the plurality of branch line segments in the cable topology structure.
Specifically, the main line node is an end point in the main line segment, and the main line segment is determined as long as the main line node is determined, so that the branch line segment can be determined.
S604, combining the main line segment and the branch line segment to obtain a cable path model.
Specifically, when combining the main line segment and the branch line segment, the main line node and all other branch line segments need to be combined to form a cable path model. Referring to FIG. 5, the main line segment is an A1-A2 line segment, and the branch line segment includes: A2-A3 segment, A3-A4 segment, A2-A5 segment and A3-A6 segment, and the main line segment and the branch line segment are combined to obtain an A1-A2-A3 path, an A1-A2-A5 path, an A1-A2-A3-A6 path and an A1-A2-A3-A4 path.
In this embodiment, the cable path model is obtained by determining a main line segment and a branch line segment from a plurality of branch line segments according to the main line node, and combining the main line segment and the branch line segment. Because the main line segment and the branch line segment are determined from the plurality of branch line segments according to the main line node, different cable path models of the cable model are comprehensively obtained according to the combination of the main line segment and the branch line segment, and an accurate cable model can be built according to the different cable path models.
The above embodiment has determined a cable path model, and based on the above embodiment, the cable path model generation cable model according to the following embodiment will be further described, as shown in fig. 7, including:
s702, a main cable section model corresponding to the main cable section and a branch cable section model corresponding to the branch cable section are obtained.
The main cable section model and the branch cable section model are cable section data models stored in a cable section model database in CST simulation software.
Specifically, when generating the cable models according to the cable path models, selecting a cable section model corresponding to the actual application, namely a main cable section model, from a cable model database for the main cable section in each cable path model; meanwhile, each branch line segment in each cable path model needs to be selected from a cable model database, and the corresponding cable section model in practical application, namely the branch cable section model, is selected.
S704, generating a cable model according to the main line segment, the main cable section model, the branch line segment and the branch cable section model.
Specifically, different cable path models are formed by a main line segment and a branch line segment, a corresponding main cable interface model is imported to the main line segment in each cable path model, and a corresponding branch cable section model is imported to the branch line segment, namely, the cable model is generated.
In this embodiment, the cable model is generated from the main cable section model, the branch cable section model, and the branch cable section model by acquiring the main cable section model corresponding to the main cable section and the branch cable section model corresponding to the branch cable section. The cable path model is used for guiding the cable section models corresponding to the main line segment and the branch line segment in practical application to generate the cable model, so that the cable model conforming to practical conditions can be accurately constructed.
The foregoing embodiments are all based on the method steps of constructing a cable model based on the cable basic model being obtained, and how to obtain the cable basic model will be further described with an embodiment, as shown in fig. 8, where the cable model constructing method further includes:
s802, importing a cable base model from a CAD application.

S804, acquiring a segmentation instruction based on a preset setting interface.
The preset setting interface refers to a preset macro command window. The window may include a cut cable and create cable node option (Trim Curves and Create Cable Nodes), a create cable node (Create Cable Bundles) option for triggering a split instruction. The splitting instruction is to split the cable in the cable basic model according to the bifurcation point.
Specifically, after the cable basic model is obtained in the CST simulation software, a macro command program which is stored in the CST simulation software in advance and is used for automatically establishing the cable model is called, a macro command window is popped up, and a user triggers a segmentation instruction by clicking a cable cutting option and creating a cable node option in the macro command window.
S806, a step of identifying a bifurcation point of the cable in the cable base model is performed according to the segmentation instruction.
Specifically, after the segmentation instruction is acquired, the system call macro command program identifies the bifurcation point of the cable in the cable base model.
In this embodiment, the step of identifying the bifurcation point of the cable in the cable base model is performed according to the segmentation instruction by importing the cable base model from the CAD application, acquiring the segmentation instruction based on the preset setting interface. Because CAD software modeling has the characteristics of simplicity and easiness in operation, CAD software is used for establishing a cable basic model simply and efficiently, a segmentation instruction is obtained through a preset setting interface, and the step of identifying the branching points of the cable in the cable basic model is executed, and only a user simply selects a preset option to trigger the segmentation instruction, so that the program automatically operates, the cable in the cable basic model is identified and segmented, and the efficiency of establishing the cable model is improved.

The method comprises the steps that nodes of each branch line segment and option labels corresponding to the nodes are determined in a main line node interface, and a user can trigger a selection instruction by clicking the option labels corresponding to the nodes, consistent with the main line nodes of the cable in practical application.
S904, determining the node corresponding to the node identifier as a main line node according to the selection instruction.

Illustratively, if the node in the select instruction is identified as O, and each node of the split segment includes H, I, J, K, L, M, N and O, the mainline node is the node whose node is identified as O.
In this embodiment, by acquiring a selection instruction based on the setting interface, according to the selection instruction, a node corresponding to the node identifier is determined as the main line node. The main line node consistent with the main line node in the practical application of the cable can be accurately obtained.
