Description

Technical Field

[0001] This invention relates to the field of safety analysis technology for complex aircraft systems, specifically to a method for rapid location, visualization assistance, and reproduction of system assembly faults. Background Technology

[0002] Complex products require the installation and fixation of numerous system components within a limited space, such as piping, wiring harnesses, electrical components, and covers. Unlike electrical components or products that form a complete system function, system components do not have self-testing capabilities during assembly and integration. When a system component malfunctions, the primary task is to obtain relevant information about the malfunctioning component, such as its name or serial number. This information is then used to retrieve specific details about the malfunctioning component, including its design, manufacturing process, and historical fault data, to assist in locating and describing the fault.

[0003] The invention patent application with publication number CN115935516A proposes a process method for constructing a fault tree for complex equipment system assembly. This fault tree construction process method includes: extracting the geometric features or assembly features of the products, grouping products with similar features into the same product family, forming a product-product family-product family feature comparison relationship; combining product families, product family features, engineering experience and historical fault data, drawing a fault tree oriented towards product family features, and assigning corresponding "fault features" and "judgment conditions" and other annotation information to each node of the fault tree; thereby realizing the explicit accumulation of fault location strategies and fault description knowledge, supporting the corresponding fault location and description.

[0004] The above technical solution will have the following main problems in actual use:

[0005] 1) Due to limitations in product coverage, personal memory, and cognitive abilities, it is difficult to quickly and accurately obtain or describe information and characteristics related to faulty products;

[0006] 2) Text-based information expression methods make it difficult to accurately express information such as the actual phenomena and spatial location of faults, and fault information is difficult to effectively transmit and reuse. Summary of the Invention

[0007] To address the problems and shortcomings of the existing technologies, this invention provides a method for rapid, visualized, and reproducible location of system assembly faults. By establishing product area annotation diagrams, lightweight 3D models of product areas, and graphical product feature annotation diagrams, operators are assisted in quickly obtaining the process features of fault points, such as geometric or assembly features, through visualization methods. The method then calls upon specific branches of the fault tree that match the corresponding features to guide the rapid and accurate location and description of the fault. Finally, the recorded spatial information of the fault location and photographs of the faulty object enable the effective transmission and reproduction of fault information.

[0008] To achieve the above-mentioned objectives, the technical solution of the present invention is as follows:

[0009] A method for rapid location, visualization assistance, and reproduction of system assembly faults, the method specifically includes the following steps:

[0010] Create a product engineering area annotation diagram;

[0011] Construct a 3D lightweight model of the product engineering area;

[0012] Construct a product family feature model;

[0013] Visual aids for fault location;

[0014] Fault information can be visualized and reproduced.

[0015] Furthermore, the establishment of the product engineering area annotation diagram includes:

[0016] According to the system assembly engineering requirements, the product space is divided into different product engineering areas. The product engineering areas are marked on the isometric drawing, plan view or 3D image of the product, and finally a product engineering area annotation diagram is formed.

[0017] Preferably, the product engineering area refers to the engineering operation area unit formed by dividing the product in space according to certain engineering constraints during the assembly process of the system product. This engineering operation area unit is the product engineering area. In this invention, the product structural parts are generally used as boundaries, and the single or multiple spaces formed by their range are used as engineering operation area units, which are the product engineering areas.

[0018] Preferably, the area identifier is composed of an area name or number and is unique.

[0019] Furthermore, the construction of the three-dimensional lightweight model of the product engineering area includes:

[0020] Based on the regions defined by the product engineering area annotation diagram, a 3D model of each region is constructed. The model is then lightweighted, while retaining the product shape data and product structure tree that are of interest during system assembly.

[0021] In this invention, the construction of a three-dimensional model of the product engineering area is a conventional method known to those skilled in the art. In this field, CATIA is generally used for model construction, but software such as UG or 3D Max can also be used.

[0022] Preferably, the product engineering area three-dimensional model refers to the three-dimensional models of all system products within the geometric space of the product engineering area and their assembly relationships, which are finally combined into a three-dimensional assembly model.

[0023] In this invention, the product structure tree is a tree-like data composed of product names and numbers that reflects the hierarchical and subordinate relationships between products and components.

[0024] Furthermore, the construction of the product family feature model includes:

[0025] On the product graphics, the process features of interest to the product family are marked and annotated, including basic characteristics, compositional characteristics, assembly characteristics, and geometric characteristics. These are represented in graphic and textual form, ultimately forming a product family feature annotation diagram with feature annotations. This feature annotation diagram is the product family feature model. Specifically, in this invention, a feature annotation diagram refers to the marking and annotation of the process features of interest to the product family on the product's plan view, isometric view, or 3D model, ultimately forming a graphic with feature annotations.

[0026] In this invention, basic characteristics refer to product design and manufacturing information associated with the product of interest, such as specifications, quality numbers, and division of labor. Component characteristics refer to the next-level components of the product of interest, which are divisible.

[0027] Furthermore, the aforementioned fault location visualization assistance refers to the process of quickly identifying and extracting faulty product information and features by loading product engineering area annotation diagrams, regional 3D lightweight models, and product family feature models during fault location. This is achieved through visualized 3D and 2D diagrams, which assist operators in recording fault marker points in the 3D model and acquiring images of the faulty object. The acquired faulty object information and features are then used to quickly match the corresponding fault tree and its branch nodes, accelerating the fault location process. Specifically, this includes the following steps:

[0028] Step S11. Obtain information on the faulty product area.

[0029] Operators can use the visual information terminal to obtain the identification information of the area where the faulty product is located based on the loaded product engineering area annotation map, and record and store it in the fault list.

[0030] Step S12. Obtain information on faulty products

[0031] Using the regional identification information obtained in step S11, the corresponding regional 3D lightweight model is loaded on the visualization information terminal. Then, the operator selects one or more 3D model instances from the 3D lightweight model to obtain the relevant information of the current faulty product on its corresponding product structure tree and records and stores it in the fault list.

[0032] Step S13. Obtain fault location and physical image information.

[0033] Operators use a visual information terminal to move the corresponding physical fault point on the loaded 3D lightweight model of the region to the fault marker point through operations such as translation, rotation, zooming in and out. The position information of the fault marker point in this state is recorded. This position information is the spatial coordinate of the fault marker point. At the same time, the physical image of the fault is captured and recorded. Finally, the position information of the fault marker point and the physical image of the fault are recorded and stored in the fault list.

[0034] Step S14. Obtain the fault tree and feature annotation diagram.

[0035] Based on the faulty product information obtained in step S12, the corresponding product family feature annotation diagram and product family fault tree are called according to the product family.

[0036] Step S15. Assisting in fault location

[0037] On the visual information terminal, operators can directly select each branch node in the fault tree through the logical relationship, branch nodes and their annotation information provided by the product family fault tree, so as to quickly locate and describe the fault, and record and store the current product characteristics and fault tree branch node information in the fault list.

[0038] Preferably, features can be selected by clicking on the loaded product family feature annotation diagram, and then several branches associated with it can be obtained in the fault tree, thereby narrowing down the possible branches of the fault tree. Selection can be made at the associated branch nodes to achieve rapid fault location and description.

[0039] Furthermore, the aforementioned fault information visualization reproduction refers to the graphical reproduction of fault information. By using recorded area identification information, faulty product information, fault marker location information, faulty physical images, product characteristics, and fault tree branch node information, the corresponding product area's 3D lightweight model, product family feature annotation diagram, and product family fault tree are invoked to display relevant information on the aforementioned visualized 2D and 3D models, thereby achieving the visualization reproduction of fault-related information. Specifically, this includes the following steps:

[0040] Step S21. Obtain fault-related information

[0041] Operators can use a visual information terminal to select the faulty products of interest from the recorded fault list, and then obtain regional identification information, faulty product information, fault marker location information, physical images of the faulty products, product characteristics, and fault tree branch node information.

[0042] Step S22. Load visualization data

[0043] Based on the regional identification information and faulty product information obtained in step S21, load the corresponding product engineering area three-dimensional lightweight model, product family feature annotation diagram and product family fault tree visualization data into the visualization information terminal.

[0044] Step S23. Reproduce the fault information

[0045] Based on the fault marker location information, fault physical image, product features, and fault tree branch node information obtained in step S21, the fault marker location information is reproduced on the 3D lightweight model of the product engineering area loaded in step S22. At the same time, the fault physical image is displayed as a floating dialog box at the fault marker. The product features and fault tree branch node information are reproduced on the product family feature annotation diagram and product family fault tree loaded in step S22, thus realizing the visual reproduction of fault information.

[0046] The beneficial effects of this invention are:

[0047] (1) The method of the present invention assists operators to quickly obtain the process characteristics of the fault point through visualization by establishing a product area annotation diagram, a three-dimensional lightweight model of the product area and a graphical product feature annotation diagram, and calling the specific branch of the fault tree that matches the corresponding characteristics to guide the rapid and accurate location and description of the fault. Finally, the fault information is effectively transmitted and reproduced by recording the spatial information of the fault point and the actual photos of the fault.

[0048] (2) The method of the present invention is based on a visualized product area annotation diagram, a three-dimensional lightweight model of the product area and a graphical product feature annotation diagram. It utilizes the visual advantages of the human body to quickly obtain faulty product information and feature information through two-dimensional and three-dimensional models, reducing the complexity and difficulty of obtaining faulty product information by traditional manual search or relying on memory, while also reducing the requirements for background knowledge of product engineering, principles and other aspects.

[0049] (3) The method of the present invention adopts a fault information expression method based on two-dimensional and three-dimensional models, which accurately expresses the actual fault phenomena and spatial location information, thus facilitating the more accurate transmission and tracing of fault information.

[0051] Figure 1 This is a flowchart of the method of the present invention;

[0052] Figure 2 This is a diagram illustrating the engineering area of ​​the product according to an embodiment of the present invention;

[0054] Figure 4 This is a diagram illustrating the product features of an embodiment of the present invention;

[0055] Figure 5 This is a schematic diagram of a product family fault tree according to an embodiment of the present invention. Detailed Implementation

[0056] To enable those skilled in the art to better understand the technical solutions of this invention, several specific embodiments will be used to further illustrate the technical solutions for achieving the objectives of this invention. It should be noted that the technical solutions claimed by this invention include, but are not limited to, the following embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort should fall within the scope of protection of this invention.

[0057] The embodiments of the present invention provide a method for rapid location visualization assistance and reproduction of system assembly faults. In this invention, the aircraft 3D model is constructed and lightweighted using engineering software such as CATIA and 3DMAX. The SpringBoot+Vue framework technology is used to realize rapid system construction and front-end and back-end separation system development. The 3D engine ThreeJS is used to load and visualize the 3D lightweight model. Through the integration of the 3D model and business data, the fault is finally located and reproduced quickly.

[0058] Embodiments of the present invention disclose a method for rapid location, visualization assistance, and reproduction of system assembly faults, as detailed in the appendix to the specification. Figure 1 As shown, the specific steps are as follows:

[0059] Step S1. Construct the product engineering area annotation diagram;

[0060] Based on certain engineering constraints, using the product's structural components as boundaries, the resulting single or multiple spaces are designated as system assembly engineering areas. The product space is divided into different work areas, and image hotspot tools are used to label the corresponding areas and their names. Commonly used image hotspot labeling tools include ImageLinks, HotspotMap, and Hotspotter. Hotspot Map, in particular, is equipped with an editor for precise drawing and spot positioning, eliminating the need to manually specify coordinates and dimensions on the image. It allows for the visual addition of annotations and text at any location, offering significant flexibility. In this practical application scenario, the Hotspot Map plugin is used to label image hotspots. On the left view of a certain type of aircraft, product areas are labeled, and corresponding area names are given, forming the hotspots as shown in the appendix of the manual. Figure 2The left-side view area of ​​a certain type of aircraft is marked, and the marked information is stored in the corresponding database.

[0061] Step S2. Construct a 3D lightweight model of the product engineering area;

[0062] Following the division of the region in step S1, 3D modeling engineering software, such as CATIA, Pro / E, UG, and 3DMAX, is used on a region-by-region basis. Since 3D modeling of aerospace products is often based on CATIA, this embodiment employs a fusion of CATIA and 3DMAX to construct and lightweight the regional 3D model. First, CATIA is used to lightweight the regional 3D model on a per-unit basis, generating CGR format files, significantly reducing the model size. Second, CATIA is used to assemble all the CGR files of the 3D model entities within a region, forming an STP format product region assembly model. Finally, 3DMAX is used to compress the lightweight product region assembly model while retaining the relevant product shape data, assembly relationships, and product structure tree information. The model size is compressed by reducing data precision and resolution, and the processed model is exported as an OBJ or MTL format file, forming a lightweight regional 3D model. The model data is then stored in the corresponding database. (Refer to the appendix of the instruction manual.) Figure 3 The figure shown is a simplified three-dimensional lightweight model of the left equipment compartment of a certain type of aircraft cockpit.

[0063] Step S3. Constructing the product family feature model;

[0064] Based on the process characteristics of interest to the product family, exemplified here as geometric and assembly features, these features are marked and annotated on the product's plan view, isometric drawing, or 3D graphics, forming a two-dimensional or three-dimensional product graphic with feature annotations, facilitating rapid identification of relevant product features. This embodiment selects the standard hexagonal head bolt GJB121.1-1986. On its plan view, using general drawing tools, the geometric features of interest during the system assembly stage—external hexagon, smooth shank, and thread—are marked and annotated, forming the figure shown in the instruction manual. Figure 4 The feature annotation diagram of the hexagonal head bolt GJB121.1-1986 is shown, and the feature annotation diagram is stored in the corresponding database; at the same time, the same image hotspot tool as in step S1 is used to mark the corresponding areas and marker names of the image as hotspots, and the marked information is stored in the corresponding database.

[0065] Step S4. Visual aids for fault location;

[0066] During fault location, the two-dimensional diagrams and three-dimensional models formed in steps S1 to S3 are loaded into the database on demand to assist operators in quickly extracting faulty product information and features. This allows for rapid matching of the corresponding fault tree and its branch nodes based on the acquired faulty object information and features. Simultaneously, fault marker location information is recorded in the three-dimensional model, and images of the faulty physical object are acquired. The specific implementation of this embodiment is as follows:

[0067] Step S41. Obtain information on the faulty product area.

[0068] On the visual information terminal, the personnel responsible for troubleshooting can select... Figure 2 The left view of a certain type of aircraft shows a hotspot. In this embodiment, the operator selects the "left equipment compartment of the cockpit" identifier to obtain the location information of the faulty product through the hotspot information, and records the current area identifier information - left equipment compartment of the cockpit in the database.

[0069] Step S42. Obtain information on faulty products

[0070] Using the area identification information obtained in step S41—the left equipment compartment of the cockpit—a lightweight 3D model of the left equipment compartment area in OBJ or MTL format is loaded onto the visualization information terminal using the ThreeJS 3D engine. Figure 3 As shown; then, the relevant operators for fault handling select the three-dimensional model entity of the fault standard part in the three-dimensional lightweight model. When selecting, the click event is bound through the onDoucmentMouseDown(event) function. Through THREE.Raycaster ray casting, the objects at the mouse click position are determined. The array of all objects at the position is returned through raycaster.intersecobjects(scene.children). The first object is selected raycaster.intersecobjects(scene.children)[0] and the object information is obtained from the database. In this embodiment, the operator selects the three-dimensional model entity of "hexagonal head bolt GJB121.1-1986" to obtain the product information of "hexagonal head bolt GJB121.1-1986" on its corresponding structure tree, and records the current "faulty product information" - "hexagonal head bolt GJB121.1-1986" in the database;

[0071] Step S43. Obtain fault location and physical image information.

[0072] On the visual information terminal, on the loaded regional 3D lightweight model, fault handling personnel can use operations such as translation, rotation, zooming in and out to drag the corresponding fault points on the 3D model and approximate their positions with the fault marker points (e.g., ...). Figure 3 The locations indicated by the fault marker (S32-fault marker) are approximately overlapping. The three-dimensional coordinates of the current marker are recorded, a mapping relationship between the number and the three-dimensional coordinates is established, a unique fault marker location number (UID) is generated, and stored in the database. At the same time, scene data is saved through the camera component on the visualization information terminal, and the fault of the physical hexagonal head bolt GJB121.1-1986 is photographed to obtain the physical image of the fault. A mapping relationship between the number and the physical image of the fault is established, a unique physical image number (UID) is generated, and stored in the database.

[0073] Step S44. Obtain the fault tree and feature annotation diagram.

[0074] Based on the faulty product information obtained in step S42 - hexagonal head bolt GJB121.1-1986, the family name and number of the product are found: hexagonal head bolt-001. Using the family name and number, the feature annotation diagram of the hexagonal head bolt-001 product family is retrieved from the linked database on the visual information terminal (e.g., ...). Figure 4 (as shown) and product family fault tree (such as Figure 5 (as shown)

[0075] Step S45. Assisting in fault location

[0076] Operators can directly judge and select each branch node in the fault tree on the visual information terminal using the logical relationships, branch nodes, and their annotations provided by the fault tree, achieving rapid fault location and description. Alternatively, they can select features by clicking on the loaded feature annotation map to narrow down the possible branches of the fault tree, achieving rapid fault location and description. This embodiment adopts the latter method. Figure 4 Mark the product with the symbol "thread" and record the current product feature information - thread - in the database; at the same time, Figure 5 The fault tree shown highlights the "thread" branch, where operators can locate faults. In this embodiment, the operator clicks... Figure 5 Upper leaf node - thread damage, record the current fault tree branch node information - thread damage in the database.

[0077] Step S5. Visualize and reproduce the fault information;

[0078] Step S51. Obtain fault-related information

[0079] This step involves the relevant personnel handling the fault selecting the faulty product of interest from a recorded list of faulty product information via a visual information terminal. In this embodiment, the operator selects the data information for the faulty product "Hexagonal Head Bolt GJB121.1-1986," thereby obtaining the following from the database: "Faulty Product Information" - Hexagonal Head Bolt GJB121.1-1986, "Area Information" - Left Equipment Cabin, "Fault Marker Location" - Fault Marker Location, "Fault Physical Image" - Fault Physical Image Information, and "Product Characteristics and Fault Tree Branch Node Information" - "Thread" on the hexagonal head bolt-001 feature annotation diagram + "Thread Damage" leaf node on the hexagonal head bolt-001 fault tree.

[0080] Step S52. Load visualization data

[0081] According to step “1),” select the obtained “Faulty Product Information” - Hex Head Bolt GJB121.1-1986 and “Regional Information” - Cockpit Left Equipment Cabin. Load the hex head bolt-001 family feature annotation diagram, hex head bolt-001 fault tree and the three-dimensional lightweight model of the cockpit left equipment cabin region in the linked database on the visualization information terminal.

[0082] Step S53. Reproduce fault information

[0083] Based on the information obtained in step "1)," including "Faulty Product Information" - Hexagonal Head Bolt GJB121.1-1986, "Fault Marker Location" information - Fault Marker Location Information, "Faulty Physical Image" information - Faulty Physical Image Information, and "Product Features and Fault Tree Branch Node Information" - Hexagonal Head Bolt-001 feature annotation diagram ("Thread") + Hexagonal Head Bolt-001 fault tree leaf node "Thread Damage," and on the 3D lightweight model of the left equipment compartment of the cockpit loaded in step "2), by linking the 3D coordinates mapped from the "Faulty Product Information" and fault marker location information in the database, the current fault point annotation is restored. The system visualizes the fault location by coloring the fault point using Three.Mesh(geometry,material) and setting it to blink to highlight its position. Simultaneously, it displays the fault image by linking to the "Fault Physical Image" mapping in the database. In step "2"), the system recreates the fault information on the product family feature annotation diagram and product family fault tree by linking to the "Product Feature and Fault Tree Branch Node Information" hexagonal head bolt-001 feature annotation diagram in the database, specifically the "Thread" attribute, along with the leaf node "Thread Damage" on the hexagonal head bolt-001 fault tree. Through these methods, the system achieves a visual reproduction of the fault information.

[0084] It should be noted that, based on the same inventive concept, the complex equipment system assembly fault tree mentioned in this embodiment is constructed by referring to the invention patent application with patent publication number CN115935516A. The fault tree constructed by the above method, as well as the system product family and feature structure tree formed in the fault tree construction process, are used as the basis to realize the rapid fault location visualization assistance and reproduction of the present invention.

[0085] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
