Description

Technical Field

[0001] The present application relates to the technical field of automobile wiring harness design and development, and in particular to a method, device, equipment and storage medium for automatically generating wiring harnesses based on principles. Background Art

[0002] With the development of industry technology, the length of vehicle wiring harnesses has increased by orders of magnitude with the increase of electrical parts. In addition to the length of the wiring harness and the definition of the interface, it also includes factors such as layout and on-site operation plan. Principle, three-dimensional layout and wiring harness drawing design are inseparable. An error in one of these links will cause abnormal function of the entire vehicle. The existing commonly used design solutions in the industry include principle design, three-dimensional layout design, and wiring harness drawing design.

[0003] For principle design, the over-matching principle is generally adopted. For solutions that include multiple manufacturers and multiple different types of braking systems, which principle to use and which items in the principle are required to be installed and optional items all need to be manually identified; and the interface relationship between the equipment and the principle is not associated. The equipment updates the interface definition. If the principle is not updated in time, it will cause abnormal function of the entire vehicle.

[0004] For three-dimensional layout design, according to different layout situations, it is necessary to convert the three-dimensional data into a two-dimensional device diagram for on-site and design data as a basis. In order to reduce the overall design data, the device Figure 1 Generally, over-matching is used, which leads to more drawing content, and the assembly data and assembly methods under different configuration conditions are different, and the readability of the drawing is poor; in addition, the length in the three-dimensional digital model needs to be measured manually and marked on the wiring harness drawing, which is prone to marking errors.

[0005] For the design of wiring harness drawings, in actual applications, for example, for wiring harness drawings of different emission standards, the workload of wiring harness design has doubled with the change of standards. In addition to the traditional hard-wired connection at the external wiring harness, it also includes special wiring harnesses such as twisted pair and external network. The associated wiring harness is associated with the functions of vehicle power, safety and comfort. Once the design is wrong, the on-site investigation takes a long time and rectification is difficult. In the design of wiring harness drawings, key components such as interface definition, wire diameter, sealing plug, etc. need to be reflected. Due to the existing design schemes, they all rely on manual interpretation of the components, circuits and docking definitions involved in the principle, and project and mark the line number, connector model and other contents. In the design process, it is easy to have marking errors or line number misalignment, missing lines or inconsistency with the principle.

[0006] It can be seen that for the existing principle design, 3D layout design, and harness drawing design, due to the urgent development nodes, most tasks cannot be fully input in advance. If the pre-cursing cannot be achieved, if the principle or layout changes during the design process, the harness cannot be notified and updated in time.

[0007] See Figure 1 As shown in the figure, it is a schematic diagram of the relationship between principle design, three-dimensional layout design, and wiring harness drawing design. Figure 1 It can be seen that the wiring harness design must be completed accurately after the principle design and three-dimensional layout design are completed, and there are many contents that need to be manually marked in the design process of the wiring harness drawings (connector model, wire diameter, blockage, etc.), which makes it difficult for the wiring harness drawings to be completely accurate; in addition, the principle design and three-dimensional layout design currently adopt over-matching design, and the optional parts require manual judgment. At the same time, the entire design steps and process require a lot of manual interpretation process, which cannot ensure the accuracy of the wiring harness. Summary of the invention

[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0045] In a first aspect, an embodiment of the present application provides a method for automatically generating a wiring harness based on principles, using an over-configured equipment library and schematic diagrams, and automatically converting three-dimensional drawings into two-dimensional drawings.

[0046] In one embodiment, referring to Figure 2 , Figure 2 This is a flow chart of the method for automatically generating a wiring harness based on the principle of this application. Figure 2 As shown, the method of automatically generating wiring harness based on the principle includes:

[0047] S1: Build a component library, establish a component electrical performance attribute library, and generate a component principle symbol library. The component library includes component digital models, interface definitions, and docking connector definitions;

[0048] Specifically, through the work of building a component library, including component digital model, interface definition, and docking connector definition, a component electrical performance attribute library is established, and a component principle symbol library is generated.

[0049] In this application, the digital model of the component includes the component's external dimensions and installation coordinate information; the interface is defined as the electrical component connector pin number and the definition of each pin, that is, the electrical component connector pins are numbered and the function of each pin is defined.

[0050] The docking connector is a component that connects with the parts and transmits signals, and the docking connector is determined according to the docking connector model definition and the part definition, and the corresponding pin definition of the docking connector is determined. Specifically, the docking connector is an important component that connects with the parts and transmits signals, and the docking connector is confirmed according to the docking connector model definition and the part definition, and the pin definition of the docking connector is clarified.

[0051] Furthermore, the interface definition of the component is attached to the digital model of the component, and the docking connector is used as the wiring harness drawing design to synchronize the matching end. That is, the interface definition of the component is attached to the 3D digital model of the component, and the docking connector is used as the subsequent wiring harness drawing design to synchronize the matching end. The component principle symbol library is associated with the component library according to the component interface definition, reflecting the component pins and definitions.

[0052] Furthermore, in one embodiment, a component library is built, a component electrical property library is established, and a component principle symbol library is generated, specifically including:

[0053] S101: Build a component electrical performance attribute library by combining 3D digital models of components, pin definitions of electrical component connectors, models of docking connectors, and corresponding interface definitions of docking connectors;

[0054] S102: Project components with electrical performance attributes to obtain relevant schematic diagrams and generate component schematic symbol libraries.

[0055] Specifically, the work of building a component library is carried out. Based on the 3D digital model of the components, the pin definition of the electrical component connector, the model of the docking connector, the corresponding interface definition of the docking connector, etc., a component electrical performance attribute library is constructed, and the relevant schematic diagrams are obtained by projecting the components with electrical performance attributes to ensure that the schematic reference content contains electrical logical relationships.

[0056] S2: Split the super-equipped principle BOM data structure according to function, and mark the optional items. According to the BOM structure, the super-equipped schematic diagram matches the component principle design with the schematic diagram;

[0057] Furthermore, in one embodiment, the over-configuration principle BOM data structure is split according to function, and the optional items are marked, specifically including:

[0058] S201: Split the over-equipment principle BOM data structure according to mandatory functions and optional functions, mark the optional items, and associate the optional items with the vehicle;

[0059] Specifically, the BOM data structure of the over-equipment principle is divided according to functions A, B, C, D, etc., and the optional items and optional items are clearly defined, and the optional items are marked (annotated). Different data structures are divided according to different functions, such as power system, vehicle control, etc.

[0060] S202: Generate a super-matching schematic diagram by combining the component principle symbol library and the split super-matching principle BOM data structure.

[0061] S3: Perform 3D assembly based on the 3D digital model of the parts, and use wiring to connect various devices and channels to form an instantiation schematic and generate instantiation drawings.

[0062] Furthermore, in one embodiment, forming an instantiation schematic diagram and generating an instantiation drawing specifically includes:

[0063] S301: The instantiated vehicle model requirements are extracted by comparing with the corresponding annotations of the super-matching principle to form an instantiated schematic diagram;

[0064] S302: The instantiation schematic diagram generates an instantiation drawing based on the 3D digital model of the component with electrical properties, and based on the docking connectors, line number definitions, wire links, and the dimensions of the 3D digital model of the component.

[0065] It should be made clear that the components, connector definitions, data structures, and schematics need to correspond one to one. The instantiated vehicle model requirements are extracted by comparing with the corresponding symbols of the super-matching principle, and finally an instantiated schematic is formed. The instantiated schematic automatically generates the corresponding instantiated drawings based on the 3D digital model with electrical properties, the associated connectors, line number definitions, and wire links, and the 3D digital model dimensions.

[0066] The method of automatically generating wiring harnesses based on principles in this application will conduct a logical closed-loop test on all configuration functions in the vehicle design and development stage, generate an over-matched three-dimensional wiring harness in combination with the background (physical environment of wiring harness layout such as frame and sheet metal), and generate an over-matched two-dimensional wiring harness drawing by projection. In the development stage of the instantiated vehicle model, the instantiated schematic diagram can be selected and generated through logo matching. For example, principle 1 corresponds to 4-channel ABS-logo 1, and principle 2 corresponds to 6 channels-logo 2. If the whole vehicle selects logo 1, the components and electrical property connection relationships corresponding to logo 2 are filtered out. The instantiated vehicle model logo extracts the corresponding three-dimensional wiring harness and two-dimensional drawings from the over-matched structure through the schematic diagram with electrical properties, and finally generates an instantiated three-dimensional wiring harness and an instantiated two-dimensional wiring harness drawing.

[0067] Through the development model of this application, it is ensured that the instantiation generation process is generated completely in accordance with the vehicle configuration requirements, reducing manual judgment of configuration combination requirements, and all electrical logic relationships ensure that the principles, layouts, and component development are developed according to the same design and development source from the beginning of library construction, avoiding inaccurate design and development problems caused by data version changes, manual interpretation, etc.

[0068] The method for automatically generating wiring harnesses based on principles in the embodiment of the present application, through the concept of forward design and development, decomposes the entire wiring harness design and development into several steps, including equipment library establishment, over-matching principles and three-dimensional assembly. Subsequently, the wiring harness drawings are automatically triggered by instantiated vehicle configuration matching. The use of this technology can ensure: 1. By establishing a parts library, the consistency of parts and principles is ensured; 2. The principles are divided into mandatory and optional according to the functional requirements of the whole vehicle, and related symbols are associated to form an over-matching principle library to ensure that the instantiated vehicle can automatically generate instantiated principles, and check the compliance of instantiated parts with principles. The definition of part changes can remind and trigger the update of principles; 3. The length and size of the wiring harness are automatically picked up and filled in from the three-dimensional model to reduce manual conversion. Subsequent equipment changes (pin definition, wire diameter) and layout changes will automatically trigger the update of the wiring harness drawings.
