Description

Technical Field

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

[0002] In the field of aircraft maintenance, during the fault inspection process, it is necessary to register fault data on the work card and transfer it to the maintenance process for implementation. When a certain number of faults accumulate, technicians need to analyze and summarize the common fault causes to improve the process plan. Since the method of text description cannot visually display the fault location, the communication efficiency in the information transfer process is not high; the fault distribution law cannot be visually displayed, resulting in technicians being unable to quickly and accurately analyze the reasons and modify the process plan. With the popularization of three-dimensional technology in the field of aircraft maintenance, fault data is registered based on three-dimensional technology on mobile terminals, and the statistical display of fault data on the digital model is realized on the computer side, realizing the full-process traceable management of aircraft fault data initiation, analysis, approval, and closed-loop.

[0003] Chinese invention patent CN104517011A (publication date: April 15, 2015) discloses a method for visualizing faults of product components based on a 3D digital model, which has four major steps, including product three-dimensional model conversion, unit-level fault information visualization design, component-level fault information visualization design, and fault monitoring process based on the visualization model. The disadvantage is that this method does not have a method for generating fault solutions.

[0004] Chinese invention patent CN108462323A (publication date: August 28, 2018) discloses a fault visualization motor and a fault visualization method thereof. Through this method, maintenance personnel can determine the fault location according to 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 order to solve the above problems, the present invention proposes a fault visualization system based on maintenance three-dimensional technology and an analysis method thereof.

[0006] A fault visualization system based on maintenance three-dimensional technology includes:

[0007] A data receiving module for importing the digital model designed by the design;

[0008] A process management module for managing three-dimensional process information, triggering the fault analysis process through fault analysis, and providing fault solutions;

[0009] A three-dimensional process editing module for editing three-dimensional processes;

[0010] A fault registration module for completing fault registration;

[0011] Other expansion modules to complete the extended application of lightweight digital models.

[0012] The data receiving module includes functions such as digital model lightweighting and design information extraction.

[0013] The data receiving module generates a lightweight digital model by calling a lightweight converter, extracts the design information in the digital model at the same time, and stores the above content in the process management module.

[0014] The process management module includes functions such as three-dimensional lightweight digital model management, three-dimensional process management, three-dimensional fault data management, three-dimensional process resource management, and three-dimensional lightweight digital model reader.

[0015] The process management module browses the stored three-dimensional lightweight digital model and three-dimensional processes by calling a three-dimensional lightweight digital model reader.

[0016] The three-dimensional process editing module triggers a three-dimensional process editor through the process management module, sends the lightweight digital model and three-dimensional process resources in the process management module to the three-dimensional process editor. After completion of editing, a three-dimensional process animation model is generated and returned to the process management module for storage and management.

[0017] The fault registration module calls a three-dimensional lightweight model reader to view the three-dimensional process animation model through an interactive electronic manual.

[0018] If fault registration is required, call the three-dimensional process editor, mark the fault at the same position with reference to the digital model, return the three-dimensional model with fault markings to the three-dimensional process management module, and view the fault summary display on the digital model through a three-dimensional lightweight model reader.

[0019] An analysis method for a fault visualization system based on maintenance three-dimensional processes is as follows:

[0020] S1. Initiate fault entry: When the fault inspection personnel perform the fault inspection process, initiate the fault entry process through a mobile terminal;

[0021] S2. Obtain fault information: The flight number, process, and basic part information are automatically obtained and imported into the fault entry process by the interactive electronic manual, and the detailed information such as fault mode and fault description is registered by the fault inspection personnel;

[0022] S3. Locate the fault point on the model: Through means such as rotation and sectioning, accurately locate the fault point on the digital model and mark the geometric position;

[0023] S4. Fault data management: Transmit the mobile terminal data to the computer terminal, accumulate the single-aircraft fault data on the aircraft type digital model for summary management, and trigger the fault analysis process at the same time;

[0024] S5. Generate a fault solution: Observe whether to initiate a fault analysis process;

[0025] S6. Use of the fault solution: Enter the single - machine fault solution into the fault knowledge base for subsequent fault solution recommendation, and at the same time send the solution to the production department for scheduling construction.

[0026] In step S5 described above, when initiating a fault analysis process, the fault is sent to the name of the technician, and the technician analyzes the fault and formulates a single - machine fault solution; if the fault analysis process is not initiated, the fault information is matched with the fault knowledge base. If the match is successful, the model - type fault solution is used as the solution to this fault. If the match is unsuccessful, the technician completes the formulation of the single - machine fault solution.

[0027] The beneficial effects of the present invention are as follows: By using lightweight digital models to solve the problem that text descriptions cannot explicitly display the fault location, it is used in the aircraft maintenance fault inspection link, effectively improving the communication efficiency in the process of fault information transmission. By summarizing faults through digital models and explicitly displaying the fault distribution law, it is beneficial for technicians to analyze the fault law based on historical faults, realizing the fully traceable management of the entire process of aircraft fault data initiation, analysis, approval, and closed - loop.

[0043] The fault registration module calls a three-dimensional lightweight model reader through an interactive electronic manual to view the three-dimensional process animation model.
