Description

Technical Field

[0001] The present invention relates to the field of aviation wiring harness technology, and in particular to a method for constructing a comprehensive wiring harness process information model. Background Art

[0002] As the "nervous system" of various industrial products, the wiring harness system connects various power systems inside complex equipment and is the guarantee for the normal operation of complex equipment functions. In the equipment manufacturing process, the manufacturing, laying, installation and power-on testing of the wiring harness are involved. The overall manufacturing process involves various types of wiring harness process information files (such as wiring tables, conduction tables, circuit schematics, three-dimensional digital models, etc.), which need to be referenced by workers and technicians. However, various types of process information files contain different information. When workers and technicians consult them, they need to search and consult many files at the same time. They rely on manual search and judgment to obtain the required information, which is extremely dependent on personnel experience and inefficient. Especially in the process of new product development, workers and technicians are not familiar with the status of the equipment, and the file consultation time is longer, which greatly affects the development cycle. Therefore, it is urgent to build a comprehensive wiring harness process model that can be used to comprehensively query wiring harness process information, reasonably and efficiently integrate the information in various wiring harness process files to achieve efficient query of wiring harness process information, and assist workers and technicians in the product manufacturing process. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiency in the prior art that all kinds of information queried in the manufacturing process of the wire harness rely on manual experience, and proposes a method for constructing a comprehensive wire harness process information model.

[0004] A method for constructing a comprehensive wire harness process information model comprises the following steps:

[0005] Step 1, obtain the circuit schematic diagram, the corresponding wiring harness three-dimensional model, the corresponding conduction table, and the corresponding wiring table required for building the model; the circuit schematic diagram includes the plug number, the dead joint number, the line number, and the associated circuit diagram number; the wiring harness three-dimensional model includes the three-dimensional digital model corresponding to the wiring harness and the three-dimensional digital model corresponding to the plug; each row in the conduction table includes the conduction source plug and pinhole, the conduction destination plug and pinhole, and the wire number information; the wiring table includes the wire number, the starting plug, the terminating plug, and the cable number information;

[0006] Step 2: traverse the conduction table, extract the conduction relationship according to the plug information and the pinhole number, and generate a line number group; and extract the corresponding information of all plugs in the conduction table to form a plug group;

[0007] Step 3, traverse the wiring table, extract the line information in the wiring table, the line information includes line number, start plug, end plug, cable number and three-dimensional digital model number; the extracted line information forms a line group;

[0008] Step 4: Form a comprehensive wiring harness process information model through the plug group, wire group, circuit schematic diagram and wiring harness three-dimensional model.

[0009] Furthermore, in step 2, the plug information includes the plug number, the pinhole number, and the cable number where the plug is located.

[0010] Furthermore, step 2 also includes the step of supplementing the missing plugs in the conduction table by traversing the wiring table to ensure that the plug group contains all the plug information.

[0011] Furthermore, when traversing the wiring table in step three, the line length of the corresponding line number in the wiring table is matched with the length of the wire harness in the three-dimensional model of the wire harness to obtain a line number-digital-analog matching table, which includes line number, bundle segment number, and cable number information.

[0012] Furthermore, in step three, the three-dimensional digital model number is obtained from the line number-digital model matching table, which is the bundle segment information in the three-dimensional digital model corresponding to the wire harness, so as to display the three-dimensional digital model of the wire.

[0013] Furthermore, when the integrated wiring harness process information model is used by users, information can be retrieved and searched by inputting the information to be searched or clicking on the circuit schematic in the software graphical interface; the searchable information includes: circuit principle, conduction relationship, plug position, cable position and direction.

[0014] Furthermore, the searched and retrieved information is displayed in the software graphical interface. The specific method is: based on the three-dimensional model of the wiring harness, combined with the wiring harness number and plug number information of the plug group, or the cable number, line number and three-dimensional digital model number of the wire group, the plug or wire is displayed in three dimensions in the comprehensive query tool.

[0015] Furthermore, the input of information to be searched or the selection of a circuit schematic in the software graphical interface is specifically performed by: identifying text data in the circuit schematic, and if it is an associated circuit diagram number, displaying the associated circuit diagram in the comprehensive query tool; or, identifying the text data input by the user to obtain the element to be searched, wherein the element to be searched is a plug number, a wire number, or a dead end number.

[0016] Furthermore, a specific method for identifying text data is to detect whether the data to be searched starts with a first special character. If so, the element to be searched is a dead joint number. If not, to detect whether the data to be searched contains a second special character. If it contains the second special character, the element to be searched is a line number. If it does not contain the second special character, to detect whether the data to be searched contains a third special character. If it contains the third special character, the element to be searched is an associated circuit diagram number. Otherwise, the information is identified as a plug number. If the data to be searched is text entered by the user, the third special character is not identified.

[0017] Furthermore, the construction of the comprehensive information model is realized as software, which is a comprehensive query tool with a graphical interface formed by secondary development of 3DVIA Composer software and AutoCAD software using a programming language for users to consult.

[0032] The present invention is further described in detail below in conjunction with test examples and specific implementation methods. However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0033] Example 1

[0034] This embodiment provides a method for constructing a comprehensive wiring harness process information model. Figure 1 As shown, the following steps are included:

[0035] Step 1, obtain the circuit schematic diagram, the corresponding wiring harness three-dimensional model, the corresponding conduction table, and the corresponding wiring table required for building the model; the circuit schematic diagram includes the plug number, the dead joint number, the line number, and the associated circuit diagram number; the wiring harness three-dimensional model contains the three-dimensional digital model corresponding to the line number and the plug; each row in the conduction table includes the conduction source plug and pinhole, the conduction destination plug and pinhole, and the number of the wires; the wiring table includes the line number, the starting plug / dead joint, the ending plug / dead joint, and the cable number information;

[0036] Step 2: traverse the conductivity table to extract plug information. The plug information includes the plug number, pinhole number, and cable number of the plug. At the same time, the conductivity relationship is extracted corresponding to the pinhole number to generate a line number group; the corresponding information of all plugs in the conductivity table is extracted to form a plug group; then traverse the wiring table to supplement the missing plugs in the conductivity table to ensure that all plug information is included in the plug group.

[0037] Step three, traverse the wiring table, match the line length of the corresponding line number in the wiring table with the length of the wire harness in the three-dimensional model of the wiring harness, and obtain the line number-digital-analog matching table, which includes information such as line number, bundle segment number, cable number, etc. At the same time, extract the line information in the wiring table, which includes line number, starting plug (dead joint), ending plug (dead joint), cable number and three-dimensional digital-analog number. The three-dimensional digital-analog number is obtained from the line number-digital-analog matching table, corresponding to the bundle segment information in the three-dimensional digital model, for the three-dimensional digital model display of the line. The extracted line information forms a line group.

[0038] Step 4: Identify the circuit diagram according to the text data in the circuit diagram. If it is an associated circuit diagram number, display the associated circuit diagram in the comprehensive query tool; or, the user inputs the text data to obtain the element to be searched, and the element to be searched is the plug number, line number, and dead joint number, which can be used by the user;

[0039] Step 5: Based on the three-dimensional model of the wiring harness, the wiring harness number and plug number information of the plug group or the cable number, line number and three-dimensional digital model number of the wire group can be combined to realize the three-dimensional display of the plug or wire for user use.

[0040] Step 6: By completing the acquisition and integration of the plug group, wire group, circuit schematic diagram and wiring harness three-dimensional model, the construction of the comprehensive wiring harness process information model is realized, and the application of the model is realized through software. During the user's use, the software graphical interface is used to input search information or click on the circuit schematic diagram to realize information viewing and search. The searchable information includes but is not limited to: circuit principle, conduction relationship, plug position, cable position and direction, etc.

[0041] The comprehensive query software is a 3D query display tool with a graphical interface formed by secondary development of 3DVIA Composer software and AutoCAD software using programming languages ​​such as C# or VB; the relevant secondary development software method is implemented through the API interface secondary development function provided in the Program Guide of 3DVIA Composer, including digital model import, digital model hiding, digital model display, structure tree information traversal, etc. The secondary development of AutoCAD is processed in conjunction with the Teigha class library, including methods such as AutoCAD file opening, clicking, zooming in and out, and information extraction. The present invention introduces the 3DVIA Composer software that can be used for secondary development, which is light, fast, and easy to maintain, ensuring reliable and convenient use; the present invention introduces the AutoCAD software that can be used for secondary development, realizing the functions of viewing circuit schematics, element point-to-point search, and circuit diagram switching.

[0042] The method of importing the circuit schematic diagram, specifically, is based on the secondary development of AutoCAD, using but not limited to the functions of the Teigha class library, and introducing the CAD circuit schematic diagram viewing function, element selection function and related circuit diagram switching into the above-mentioned comprehensive query tool;

[0043] The data searched by the user is identified, and then the element to be searched is searched in the wire group and plug group information to obtain the corresponding wire harness process information.

[0044] The specific method is to detect whether the data to be searched starts with the first special character "s". If so, the element to be searched is the dead joint number. If not, detect whether the data to be searched contains the second special character "-". If it contains the second special character, the element to be searched is the line number. If it does not contain the second special character "-", detect whether the data to be searched contains the third special character " / ". If it contains the third special character " / ", the element to be searched is the associated circuit diagram number. Otherwise, it is identified as the plug number.

[0045] Since all kinds of information in the circuit schematic have their own unique formats, and the information is all text data, the corresponding features in the string can be identified (such as the line number contains the "-" character, the dead joint starts with the "s" character, the associated circuit diagram number contains " / " and other features of the elements in the circuit schematic), and then the plug number, line number, dead joint number and associated circuit diagram number can be identified. Clicking on different elements will send different data to the comprehensive query interface, thereby displaying the corresponding results. For different manufacturers or schematic designers, the relevant rules may be different, and the identification rules can be adjusted according to actual conditions.

[0046] The present invention uses a comprehensive wiring harness process information model construction method, which constructs a set of comprehensive wiring harness process information models. By combining the model to build comprehensive query software, it is possible to directly query the wiring harness process information (such as wiring table, conduction table, etc.) as needed, and can also view the circuit schematic diagram and query the schematic element information in real time, and introduce a three-dimensional display function to realize the three-dimensional display of the wiring harness installation, laying path and plug position. It reduces the difficulty of information query and troubleshooting, improves the efficiency of equipment manufacturing and testing, and shortens the troubleshooting cycle of power-on testing.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
