Description

Technical Field

[0001] The invention relates to the technical field of aircraft maintenance technology, and in particular to a fault visualization system based on three-dimensional maintenance technology and an analysis method thereof. Background Art

[0002] In the field of aircraft maintenance, the inspection process needs to register fault data on the work card and pass it to the maintenance process for maintenance. When a certain number of faults accumulate, technicians are required to analyze and summarize the common causes of faults to improve the process plan. Since the text description method cannot explicitly display the fault location, the communication efficiency of the information transmission process is low; the failure to explicitly display the fault distribution pattern causes the technicians to be unable to quickly and accurately analyze the cause and modify the process plan. With the popularization of three-dimensional technology in the field of aircraft maintenance, the fault data is registered on the mobile terminal based on the three-dimensional process, and the statistical display of the fault data in the digital model is realized on the computer side, realizing the traceable management of the entire process of aircraft fault data initiation, analysis, approval, and closed loop.

[0003] However, the applicant found that the Chinese invention patent with publication number CN104517011A disclosed a product component fault visualization method based on 3D digital model, which has four major steps, including product 3D model conversion, unit-level fault information visualization design, component-level fault information visualization design, and fault monitoring process based on visualization model. The disadvantage is that this method does not generate a fault solution method.

[0004] Another example is the Chinese invention patent with publication number CN108462323A, which discloses a fault visualization motor and a fault visualization method thereof. This method enables maintenance personnel to determine the fault location based on the displayed operating parameter values ​​when the motor fails. It does not involve the field of aircraft maintenance and is only applicable to motor products. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a fault visualization system and an analysis method thereof based on a three-dimensional maintenance process, which solves the technical problem that the traditional method of using text descriptions cannot explicitly display the fault location.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a fault visualization system based on maintenance three-dimensional process, the system comprising:

[0007] A data receiving module, the data receiving module is used to receive the three-dimensional model of the corresponding maintenance fault inspection target, generate a lightweight digital model by calling a lightweight converter, and extract the design information in the three-dimensional model to form three-dimensional process information and store it in the process management module;

[0008] A process management module, which is used to manage lightweight digital models and three-dimensional process information, complete the fault analysis process through fault analysis triggers, and provide fault solutions;

[0009] A three-dimensional process editing module, which is triggered by the process management module and is used to edit the lightweight digital model and three-dimensional process information, and generate a three-dimensional process animation model and then import it into the process management module;

[0010] A fault registration module, which is used to check the three-dimensional process animation model and complete the fault registration;

[0011] Other extension modules, wherein the other extension modules complete the extended application of lightweight digital models by calling lightweight digital models into other systems.

[0012] Furthermore, the process management module includes a fault knowledge base for storing lightweight digital models and three-dimensional process information and a three-dimensional lightweight model reader A.

[0013] Furthermore, the three-dimensional process editing module includes a three-dimensional process editor A for editing lightweight digital models and three-dimensional process information.

[0014] Furthermore, the three-dimensional process editing module triggers the three-dimensional process editor A through the process management module, sends the lightweight digital model and three-dimensional process information in the process management module to the three-dimensional process editor A, generates a three-dimensional process animation model after editing is completed, and returns to the process management module for storage and management.

[0015] Furthermore, the fault registration module includes a three-dimensional process editor B for marking faults in the three-dimensional process animation model by comparing with the lightweight digital model, and a three-dimensional lightweight model reader B for reviewing the fault summary display on the three-dimensional process animation model. The fault registration module calls the three-dimensional lightweight model reader B through an interactive electronic manual to review the three-dimensional process animation model.

[0016] Further, in the fault registration module, completing the fault registration includes:

[0017] If fault registration is required, the 3D process editor B is called to mark the fault at the same position of the 3D process animation model against the lightweight digital model, and the 3D process animation model with the fault marking is transferred to the 3D process management module for storage.

[0018] The technical solution also provides an analysis method applied to the above fault visualization system, the method comprising the following steps:

[0019] S1. Initiate fault entry: When the fault inspection personnel are performing the fault inspection process, they initiate the fault entry process through the mobile terminal;

[0020] S2. Fault information acquisition: The basic information of the rack number, process, and parts is automatically acquired from the interactive electronic manual and imported into the fault entry process. The detailed information of the fault mode and fault description is registered by the fault inspection personnel;

[0021] S3. Locate the fault point on the model: Use rotation and sectioning to accurately locate the fault point on the 3D process animation model by comparing the lightweight digital model, and mark the geometric position;

[0022] S4, fault data management: transfer the mobile terminal data to the computer, and accumulate the single machine fault data to the 3D process animation model of the corresponding machine model for summary management, and trigger the fault analysis process at the same time;

[0023] S5. Generate fault solution: observe whether to initiate the fault analysis process;

[0024] S6. Use of fault solutions: Enter the single-machine fault solution into the fault knowledge base for subsequent fault solution recommendations, and send the fault solution to the production department for production scheduling and construction.

[0025] Furthermore, in step S5, specifically:

[0026] If a fault analysis process is initiated, the fault will be sent to a technician, who will analyze the fault and develop a single-machine fault solution;

[0027] If the fault analysis process is not initiated, the fault information will be matched with the fault knowledge base. If the match is successful, the model fault solution will be used as the solution to the fault. If the match is unsuccessful, the technical staff will complete the formulation of a single machine fault solution.

[0028] By means of the above technical solution, the present invention provides a fault visualization system based on maintenance three-dimensional process and its analysis method, which has at least the following beneficial effects:

[0029] 1. The present invention solves the problem that text description cannot explicitly show the fault location through lightweight digital models, and is used in the aircraft maintenance fault inspection link to effectively improve the communication efficiency of the fault information transmission process.
