Description

Technical Field

[0001] This invention relates to the field of aircraft electrical wiring harness design, and more specifically, to a method and system for the interaction of two-dimensional logical data and three-dimensional physical data for aircraft wiring harnesses. Background Technology

[0002] Currently, in aircraft wiring harness design, signal logic and wiring relationships are designed using two-dimensional system electrical schematics or electrical circuit diagrams, with related design results and data stored in two-dimensional design software, such as Siemens' CHS software. Conversely, the three-dimensional spatial installation design of wiring harnesses is designed using three-dimensional digital models of wiring harness installation, with related design results and data stored in three-dimensional installation design software, such as Dassault Systèmes' CATIA software.

[0003] However, the 3D installation design of aircraft wiring harnesses requires 2D signal wiring information, and similarly, the 2D wiring diagram design of aircraft requires 3D conductor length information. Other scenarios, such as wiring harness safety analysis and line voltage drop current carrying capacity calculation, also require the simultaneous use of 2D and 3D wiring harness data. Therefore, a method is needed to enable the interaction between 2D logical data and 3D physical data of aircraft wiring harnesses.

[0004] Analysis of existing technologies reveals that currently used industry software such as CHS and CATIA do not offer native wire harness data interaction capabilities, and other existing technologies also lack relevant solutions. In existing aircraft wire harness design processes, it is typically necessary to export two-dimensional and three-dimensional wiring data separately, and then find the correspondence between them based on the terminal connection device's serial number. This approach is not only inefficient and labor-intensive, but also highly susceptible to human error when processing the massive amounts of data (millions of records) in aircraft wire harness design, posing a potential risk to the accuracy and reliability of the design work.

[0005] Therefore, there is a need in this field for improved technologies to realize the interaction between two-dimensional logical data and three-dimensional physical data of aircraft wiring harnesses. Summary of the Invention

[0034] The accompanying drawings are not drawn to scale. Detailed Implementation

[0035] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0037] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this disclosure.

[0040] Figure 1A flowchart illustrating a method for interacting two-dimensional logical data and three-dimensional physical data for an aircraft wiring harness according to an embodiment of the present invention is shown.

[0041] like Figure 1 As shown, in step 102, a storage unit can be set up to store information associated with multiple wires in the aircraft wiring harness.

[0042] In a non-limiting example, the information associated with the plurality of conductors may include: conductor attribute information; conductor path information; and channel physical location information.

[0043] In a further non-limiting example, setting up a storage unit may include: creating a storage table for each type of information in the information; and linking the storage tables using a universally unique identifier to store the information.

[0044] In step 104, a two-dimensional data interface for the multiple wires can be constructed based on the storage unit.

[0045] In a non-limiting example, a two-dimensional data interface can be used to display information associated with the plurality of wires.

[0046] In step 106, communication between the two-dimensional data interface and the three-dimensional engine can be established.

[0047] In a non-limiting example, establishing communication between the 2D data interface and the 3D engine may include: embedding the 3D engine into the main window interface of a cross-platform application development framework, and calling the application programming interface associated with the 3D engine to achieve customized development.

[0048] In step 108, the three-dimensional digital model of the multiple wires can be reproduced in the three-dimensional engine.

[0049] In a non-limiting example, reproducing the 3D model of the plurality of conductors in a 3D engine may include: reproducing the structure tree of the plurality of conductors in a window of the 3D engine, the structure tree including the starting device, ending device, points where the conductors enter channels, and conductor paths; and reproducing the 3D model of the plurality of conductors in a window of the 3D engine, the 3D model including combinations of multiple channels, the access points of the multiple channels, and fly lines between corresponding starting devices and / or corresponding ending devices.

[0050] The following provides two examples of interaction: one by selecting a 3D model in the 3D engine, and the other by selecting a wire in the 2D data interface.

[0051] In a non-limiting example, the interaction between the two-dimensional data of the plurality of conductors and the three-dimensional model may include: in response to selecting the three-dimensional model in the three-dimensional engine, determining the name of the geometry set corresponding to the three-dimensional model; and searching for data corresponding to the name of the geometry set in an embedded cross-platform application development framework, thereby displaying information associated with the plurality of conductors in the selected three-dimensional model in the two-dimensional data interface.

[0052] In a non-limiting example, the interaction between the two-dimensional data and the three-dimensional model of the plurality of wires may include: in response to selecting a wire in the two-dimensional data interface, determining the cable name corresponding to the selected wire; and searching for the data corresponding to the cable name in an embedded cross-platform application development framework, thereby locating the three-dimensional model associated with the selected wire in the three-dimensional engine.

[0053] In step 110, the interaction between the two-dimensional data of the multiple wires and the three-dimensional digital model can be achieved through the application programming interface associated with the three-dimensional engine.

[0054] The above describes the interaction method between two-dimensional logical data and three-dimensional physical data of the present invention. By converting the two-dimensional logical data and three-dimensional spatial path model of the conductor into structured data and storing it in a database, and building a front-end interface to communicate with the database, the conductor data in the database is called to present a view, and then the three-dimensional engine is driven in the form of an interface to complete the reproduction of the three-dimensional model of the conductor, thereby realizing the interaction between two-dimensional logical data and three-dimensional physical data of aircraft wiring harness.

[0055] Figure 2 A schematic diagram of a harness interaction framework for an interaction system of two-dimensional logical data and three-dimensional physical data according to an embodiment of the present invention is shown. Figure 2 As shown, the interactive system adopts a front-end and back-end separation model. The front-end creates a two-dimensional data operation platform 202 and a three-dimensional digital model operation platform 204, while the back-end can, for example, use an Oracle database 206. By creating structured data in the Oracle database 206, the three-dimensional model is converted into three-dimensional data for storage, and a mapping relationship between two-dimensional data and three-dimensional data is established.

[0056] Specifically, to achieve communication and data interaction between different systems, and to support data interaction between the front-end and back-end, the functionality of the data interface layer 212 can be implemented, for example, using WebService interface technology. That is, the back-end can provide data interfaces through WebService, and the front-end can obtain data or submit requests by calling these interfaces. In back-end development, the Java programming language can be primarily used, and the mainstream Spring Boot framework can be adopted to integrate various related components. Through the powerful features of the Spring Boot framework, efficient and scalable back-end services can be quickly built. To implement the data persistence layer, the MyBatis framework 210 can be used. MyBatis framework 210 supports customized SQL (Structured Query Language), stored procedures, and advanced mappings, meeting the needs of complex business logic. Furthermore, through simple XML or annotations, the MyBatis framework 210 can flexibly configure and map native information, thereby achieving efficient data operations. In addition, to provide efficient database connection management, the Druid data connection pool 208 can be used. The Druid data connection pool 208 not only optimizes database connection performance but also provides powerful monitoring and security protection functions. This architectural design ensures system flexibility, scalability, and high performance, while meeting the needs of enterprise-level application development. In this system, annotations are used to map interfaces and Java POJOs (Java Entity Class Objects) to records in the database, further simplifying the development process and improving efficiency.

[0057] The following combination Figure 2 This example illustrates a harness interaction process using a harness interaction framework. This example is related to the reference... Figure 1 The corresponding interaction method includes five steps: establishing a storage unit, constructing a front-end interface, establishing communication, reproducing the 3D digital model, and realizing interaction. This achieves the process of transferring wire data from the database to the front-end interface and then reproducing it in the 3D digital model. The specific process is as follows:

[0058] (1) Create a storage unit in a database (such as Oracle Database 206) to store wire data. Link wire attributes with information such as wire paths through bridging relationships.

[0059] Specifically, data storage units can be established based on signal logic and physical installation data to store conductor attribute information, conductor path information, and channel physical location information. A separate data table can be created for each type of information, and these tables can be linked using, for example, a UUID (Universally Unique Identifier) ​​to achieve complete conductor information storage.

[0060] Figure 3A schematic diagram of conductor information according to an embodiment of the present invention is shown. The data table of conductor information may include attributes such as conductor name, wire gauge, conductor part number, conductor type, and the type of multi-core wire it belongs to.

[0061] Figure 4 A schematic diagram of connector information according to an embodiment of the present invention is shown. The connector information data table only displays the connector's own attributes, including connector name, connector part number, device to which it belongs, and connector coordinates.

[0062] Figure 5 A schematic diagram of device information according to an embodiment of the present invention is shown. The data table of this device information only displays the device's own attributes, including device name, device part number, device type, and device coordinates.

[0063] Figure 6 A schematic diagram of pin information according to an embodiment of the present invention is shown. The pin information data table only displays the pin's own attributes, including hole number, associated connector, and associated device.

[0064] Figure 7 A schematic diagram of path information according to an embodiment of the present invention is shown. The data table of the path information records various attributes of a path, including the start and end positions of the path, the total length of the path, and the channels traversed, etc.

[0065] Figure 8 A schematic diagram of conductor information according to an embodiment of the present invention is shown. The conductor information data table (also referred to as a conductor data splicing table) uses the UUIDs of various conductor attributes and... Figures 3 to 7 The relevant information shown can be linked together to form a complete wire, which may include the wire name, the devices connected at both ends, connectors, pins, and the path of the wire itself.

[0066] (2) Construct a two-dimensional data interface front-end (such as a two-dimensional data operation platform 202). Through data communication, the wire data is presented on the front-end two-dimensional data interface.

[0067] Specifically, a conductor data interface (i.e., a two-dimensional data interface) can be established to display various attributes of the conductor. This interface can include functions such as data search and filtering, allowing conductor data to be displayed using customized conditions.

[0068] Figure 9 A schematic diagram of a two-dimensional data interface according to an embodiment of the present invention is shown. Figure 10 This is a schematic diagram of a wire data item according to an embodiment of the present invention. Figure 9The text displays various attributes of wires, including drawing number, configuration, isolation code, end-to-end device, connector, hole number, path, etc., organized by wire. All displayed wire attributes (i.e., data items) are shown below. Figure 10 As shown.

[0069] (3) Establish communication between the two-dimensional data interface (such as the two-dimensional data operation platform 202) and the three-dimensional engine to realize the rendering, display, dragging, and rotation of the three-dimensional model.

[0070] Specifically, communication can be established between the guide wire data interface (i.e., the two-dimensional data interface) and the CATIA software (i.e., a three-dimensional engine). CATIA (e.g., CATIA V5R18) can be embedded into the main window interface of Qt (i.e., a cross-platform application development framework). Custom development can be achieved by calling the relevant APIs (Application Programming Interfaces) of CATIA Automation elements such as 3D view control in the background. The above operations can be mainly divided into two parts: starting CATIA, which involves using a Python script to read the registry information of the local machine, automatically identifying multiple installed CATIA versions, and accurately starting the target version CATIA V5R18 (preferably the 64-bit version); and controlling CATIA, which involves using a Qt application to perform three-dimensional interactive operations on CATIA through the Automation API after successfully starting CATIA V5R18.

[0071] in addition, Figure 11 A schematic diagram of a QT / CATIA integration plugin according to an embodiment of the present invention is shown. The following four functions can be packaged into an executable toolkit using the Python packaging tool pyinstaller, allowing Qt to call them through a thread interface, thus implementing logical control functions for CATIA and Windows within Qt:

[0072] 1) BrowseReg_startV5R18.exe: Starts the local CATIA V5R18. Development logic: Obtains the necessary CATIA V5R18 installation path through the registry retrieval interface, then picks up parameters such as CATIA environment variables from different machines to compose a startup script to achieve the startup function.

[0073] 2) embed_in_CATIA.exe: Embeds CATIA V5R18 into the Qt main window interface. Development logic: Obtains the PID numbers of the active process CATIA V5R18 and the Qt main interface through the registry retrieval interface, and uses the Windows window interface to set parent and child windows to achieve the embedding function.

[0074] 3) embed_out_CATIA.exe: Embeds CATIA V5R18 out of the Qt main window interface. Development logic: Obtains the PID numbers of the active process CATIA V5R18 and the Qt main interface through the registry retrieval interface, and uses the Windows window interface to set parent and child windows to achieve the embedding function.

[0075] 4) `if_one_CNEXT_exe_and_Check_V5R18.exe`: This function checks if only one CATIA instance is running in the background and if the running version is V5 R18. Development logic: It retrieves background processes named `CNEXT.exe` or `CNEXT*32.exe` through a registry search interface. For processes that meet the criteria, it switches to a Qt QAxObject object for control, and uses the CATIA Automation API to obtain the prepared CATIA version information to implement the detection function.

[0076] Figure 12 A schematic diagram of an integrated two-dimensional data interface and CATIA according to an embodiment of the present invention is shown, that is, CATIA is embedded in a two-dimensional data interface (i.e., a wire data interface).

[0077] (4) By setting buttons in the 3D interface (such as the 3D digital model operation platform 204), relevant elements of the secondary development of the 3D engine can be called, and the points and lines of the conductor can be drawn in the 3D interface. The expression of the conductor in the 3D interface structure tree is organized, including the starting device, the channel through which it passes, and the ending device, and finally a 3D digital model of the conductor is formed.

[0078] Figure 13 A schematic diagram of wire analog-to-digital reproduction according to an embodiment of the present invention is shown. Figure 13 As shown, in the window of the 3D engine (i.e., the 3D interface, such as the 3D digital model operation platform 204), the left side is a structure tree, which includes information such as the starting and ending devices, the points where the wires enter the channel, and the specific wire paths.

[0079] The basic principle of reproducing the digital model of a conductor is as follows:

[0080] 1) Create MBD: Use Qt's QAxObject object to control the CATIA process object, and combine business logic to call the relevant APIs of MBD elements in CATIA Automation to achieve customized development.

[0081] 2) Measurement and drawing of elements such as points and lines in signal laying: Use Qt's QAxObject object to control the CATIA process object, and combine business logic to call the relevant APIs of geometric sets, measurement, geometry and other elements in CATIA Automation to achieve customized development.

[0082] 3) Refreshing the structure tree, centering, and centering the model: Using Qt's QAxObject object to control the CATIA process object, and combining business logic to call the relevant APIs of elements such as 3D view control in CATIA Automation, to achieve customized development.

[0083] The final drawn conductor topology digital model (i.e., 3D digital model) is as follows: Figure 13 As shown on the right, the conductor digital model is a combination of multiple channels, as well as the flying wires of the channel access points and equipment.

[0084] (5) Use the program to control the traverse model in the 3D engine, and combine the business logic to call the API (Application Programming Interface) related to the 3D view control and other elements to realize the interaction between the traverse's 2D data and the 3D model.

[0085] Specifically, the interaction between 2D data and 3D models of conductors can be achieved by using APIs related to elements such as 3D view control in CATIA Automation. By selecting the 3D model of the conductor in CATIA, the selected conductor can be located in the 2D data interface, as follows:

[0086] 1) Select a model and obtain the name of the selected CATIA geometry set (VB Automation).

[0087] 2) Obtain the CATIA project file in the activity through the COM object management function in QAxObject, and then read the name of the geometry set (Qt C++).

[0088] 3) Search for rows with the same name in the Qt data interface, and locate unique data by combining factors such as project and configuration (Qt C++).

[0089] 4) This principle can be used to find the set of wires within a certain path.

[0090] Alternatively, you can select the conductor in the 2D data interface to highlight and center the selected conductor's digital model in CATIA. The method is as follows:

[0091] 1) Select a data entry and retrieve the cable name.

[0092] 2) Call VB Automation to read this value and locate this digital model in CATIA.

[0093] You can understand; the above is for reference only. Figures 2 to 13 The described harness interaction process is merely exemplary and can be adjusted, modified, added, and / or deleted according to actual needs, as long as it achieves the desired result. Figure 1 The aforementioned method for interacting between two-dimensional logical data and three-dimensional physical data is sufficient.

Compared with the solutions in the prior art, the present invention has at least the following advantages:

[0100] (1) By linking the three-dimensional digital model of the conductor with the two-dimensional data, the real-time interaction between the conductor data and the digital model is realized, which is conducive to improving the quality and efficiency of the harness design and can support the work of harness safety analysis, line voltage drop performance analysis and other tasks.

[0101] (2) By integrating the logical view of the conductor with the digital model view, the correspondence between the logical attributes of the conductor and the three-dimensional installation attributes can be displayed intuitively, so that the harness can be designed simultaneously from both logical and physical perspectives.

[0102] In summary, this invention solves the problems of low efficiency and high workload caused by manually searching for corresponding relationships based on the device numbers of terminal wiring devices in existing aircraft wiring harness designs, and avoids the potential risk of human error. The interaction method between two-dimensional logical data and three-dimensional physical data of aircraft wiring harnesses defined in this invention can significantly improve the quality and efficiency of aircraft wiring harness design, and conveniently support tasks such as wiring harness safety analysis and line voltage drop performance analysis.
