Abstract
Description
Technical Field
[0001] This invention relates to the field of aircraft maintenance auxiliary tools, and in particular to an aircraft maintenance production preparation auxiliary system. Background Technology
[0002] In aircraft maintenance, specifically for civil aircraft such as the A320 and A330 series, the core task of the maintenance production preparation phase is to analyze the Aircraft Maintenance Manual (AMM) based on the aircraft troubleshooting plan to generate a production preparation list, including resource information such as required tools, aviation materials, chemicals, and torque values. Traditionally, this process relies on manual operation, requiring maintenance personnel to manually review and organize highly specialized technical documents to ensure the accuracy and safety of the maintenance work. Current production preparation work depends entirely on manually reviewing work cards and related information in the troubleshooting plan. However, manual operation is prone to omissions or errors due to fatigue or lack of experience. The accuracy of production preparation heavily depends on the professional level and sense of responsibility of engineers, resulting in low and unstable work efficiency during the preparation process, extending the overall maintenance time, and increasing the labor intensity and time consumption of personnel. Therefore, to address these shortcomings, an aircraft maintenance production preparation auxiliary system is proposed. Summary of the Invention
[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an auxiliary system for aircraft maintenance production preparation, which solves the problems of low and unstable work efficiency, increased workload and time consumption caused by relying entirely on manual operation in the preparation process.
[0004] (II) Technical Solution To address the above problems, the present invention provides an aircraft maintenance production preparation auxiliary system, comprising: The system comprises a data collection module, an information identification module, a data processing module, and a list generation module. The data collection module collects work parameters during aircraft maintenance. The information identification module includes an aircraft information identification unit and a work card information identification unit. After identifying the content of the plan, the information identification module sends it to the data processing module. The data processing module determines the work items to be performed based on the information collected by the information identification module, and then retrieves the corresponding work parameters from the data collection module and sends them to the list generation module. The list generation module summarizes the received work parameters to generate a work list and sends it to the staff.
[0005] Preferably, the data collection module stores aircraft maintenance manual information, and the data processing module retrieves the required information from the aircraft maintenance manual information in the data collection module according to the received scheme content.

[0008] Preferably, the work card information includes a function classification field. The data processing module determines the work card category based on the function classification field of the work card information and the result of the work card category determination is used as the basis for the determination.
[0009] Preferably, the data processing module is connected to the aviation material management system and retrieves information on various aviation materials from the aviation material management system.

[0012] (III) Beneficial Effects The aircraft maintenance production preparation auxiliary system provided by this invention collects and stores aircraft maintenance manual information through a data collection module. During the preparation stage of maintenance work, after identifying the aircraft model information and work card information that need to be maintained, the data processing module retrieves the working parameters that match the identified information from the aircraft maintenance manual information in the data collection module and summarizes and sends them to the list generation module. The list generation module automatically generates a maintenance list and sends it to the staff. Thus, the system achieves automatic identification and integration of data during the preparation stage of aircraft maintenance work, eliminating the need for staff to manually query and summarize data, reducing the labor intensity and workload of staff, and improving the work efficiency of aircraft maintenance work. Attached Figure Description
[0013] Figure 1 This is a schematic diagram of the structure of the aircraft maintenance production preparation auxiliary system of the present invention. Detailed Implementation
[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0015] In the description of this invention, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "inner", "outer", "top", and "bottom" are based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this invention and to simplify the description. It is not intended to indicate or imply that the component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.
[0016] like Figure 1 As shown, the present invention provides an auxiliary system for aircraft maintenance production preparation, specifically including: The system comprises a data collection module, an information identification module, a data processing module, and a list generation module. The data collection module collects operational parameters during aircraft maintenance. To ensure the accuracy and safety of aircraft maintenance, operations and parameters must be strictly performed in accordance with relevant regulations, and each maintenance operation must be verified to meet requirements. To shorten the time required for determining and retrieving operational procedures, personnel collect and store the necessary operational parameters before maintenance work begins using the data collection module. Subsequent retrieval of these parameters is then simpler, facilitating subsequent parameter lookup and confirmation.
[0017] During the preparation phase of aircraft maintenance work, it is necessary to consult the Aircraft Maintenance Manual (AMM) for the specific procedures and required aircraft parts based on the actual work content and the target aircraft type. The data collection module collects and stores aircraft maintenance manual (AMM) information, while the data processing module retrieves the necessary information from the AMM based on the received solution. Typically, all operational parameters used in aircraft maintenance are recorded in the AMM. Workers retrieve the corresponding parameters and procedures from the AMM based on the type of maintenance work, project, and target aircraft model. However, due to the vast amount of information in the AMM and the fact that related or interconnected operational parameters often reside in different chapters, manually retrieving workflows, parameters, and information from the AMM is extremely difficult. To facilitate the retrieval of data and operational parameters, the data collection module collects and stores relevant data, including the AMM. Then, during aircraft maintenance, the necessary workflows, parameters, and materials can be retrieved directly from the data collection module based on the identified information.
[0018] In practice, aircraft maintenance units typically have systems or storage media, such as hard drives or web pages, to store aircraft maintenance manuals (AMMs). Staff can connect the data collection module to the existing storage media or operating system and collect the stored AMM information, eliminating the need to store the AMM content and thus shortening the time spent on system construction.
[0019] The solution includes aircraft model information and work card information. The information recognition module includes an aircraft information recognition unit and a work card information recognition unit. After recognizing the solution content, the information recognition module reads the corresponding work information and sends it to the data processing module. During the work process, the aircraft information recognition unit identifies the aircraft model requiring maintenance, and the work card information recognition unit identifies the work card information entered by the worker. The specific operational details for the same maintenance work differ depending on the aircraft model. Therefore, when retrieving work parameters, it is necessary to first determine the specific model of the target aircraft. At this time, the data processing module retrieves the AMM information matching the target model from the data collection module, and then retrieves the corresponding maintenance parameters from the AMM information based on the identified work card information.
[0020] The work card recognition unit includes a fuzzy recognition unit that matches the correct work card number based on the input partial work card information and retrieves the corresponding work card information from the data collection module. Typically, the work card recognition unit uses regular expression matching to compare the recognized work card information with the actual work card information.
[0021] To improve the efficiency of the information recognition module and data processing module in retrieving maintenance work information, a specific field of the work card number is typically used as a functional classification field. After recognizing the work card number, the information recognition module first determines the category of the work card information based on the classification field. The data processing module then labels the work parameters retrieved for the same work card information based on the functional classification field and sends the labeling results along with the work card information to the list generation module. The labeled information is then matched with the work card information used by the staff, and the list generation module compiles and generates a work list.
[0022] Typically, the correspondence between the classification field in the work card number and the corresponding classification result is as follows: (1) 000-Removal category: includes operations such as disassembly, disconnection, and deactivation, with corresponding category fields distributed between 000 and 090; (2) 100-Cleaning category: including chemical / mechanical cleaning, paint stripping and other operations, with corresponding classification fields ranging from 100 to 170; (3) 200-Inspection category: includes visual inspection, NDT inspection, detailed inspection and other operations, with the corresponding classification fields distributed between 200 and 290; (4) 300-Repair category: includes operations such as welding, machining, and composite material repair, with corresponding classification fields ranging from 300 to 390; (5) 400-Installation category: includes operations such as component installation, reconnection, and activation, with corresponding category fields distributed between 400 and 490; (6) 500-Processing category: includes operations such as transportation, packaging, and storage, with corresponding classification fields ranging from 500 to 580; (7) 600-Service Category: Includes operations such as refueling, lubrication, and protection, with corresponding category fields distributed between 600 and 680; (8) 700-Test category: includes functional testing, system testing, operation testing and other operations, with the corresponding category fields distributed between 700 and 790; (8) 800-Miscellaneous: including fault isolation, adjustment, calibration, preparation, recovery, system configuration, etc., with corresponding fields distributed between 800 and 890; (9) 900-Other: This category includes standard practices, periodic replacements, and other operations. The corresponding classification fields are distributed between 910 and 990.
[0023] To improve work efficiency, the output of the fuzzy recognition unit typically displays the most frequently used employee card number. When an employee enters an employee card number, if the card number matches the one displayed on the output, the employee can directly select the corresponding card number, skipping the process of entering the card number and recognizing the card information. In actual work, the classification results of the employee card numbers and the corresponding classification fields can be adjusted according to actual work requirements.
[0024] The data processing module determines the required work items based on the information collected by the information recognition module, and then retrieves the corresponding work parameters from the information recognition module and sends them to the list generation module. The data processing module connects to the aircraft material management system and retrieves information on various aircraft materials from the system. This information includes the quantity, name, and storage location of the materials. This information, along with the work parameters, is sent to the list generation module. Typically, each work card corresponds to one maintenance task. However, performing one maintenance task may require multiple related maintenance tasks, such as disassembling the outer shell. Each related maintenance task corresponds to a work card, and the work card used for the related maintenance task in this work is the sub-work card for this task. When retrieving the corresponding AMM manual information, the data processing module also needs to determine the aircraft material information required for the corresponding auxiliary work based on the procedures performed by the sub-work card, and retrieve all necessary tools and specific storage information for the aircraft materials from the on-site aircraft material management system, such as storage location, part number, and required quantity. After the required aviation materials information is compiled, it is sent to the list generation module. The staff will judge the feasibility of the maintenance work and the specific execution time limit based on the storage status of each aviation material in the list generation module. For example, if the storage location of the aviation materials is too far away from the construction location, it means that the maintenance work cannot be carried out in a short period of time and needs to be temporarily put on hold while waiting for the aviation materials to be retrieved.
[0025] In existing technologies, this process typically requires staff to consult the AMM manual, then use the manual's contents to search the aircraft parts manual and the aircraft parts management system to obtain and integrate the aircraft parts storage information, significantly extending the preparation time for aircraft maintenance work. In this invention, through the cooperation of various modules, the corresponding tool and aircraft parts information can be automatically obtained based on aircraft information and work card number information.
[0026] The data processing module extracts warning and alert information corresponding to the maintenance work performed from the data collection module, and then organizes and sends this information to the inventory generation module. The AMM manual contains warning and alert information to remind staff of precautions to follow when performing maintenance tasks. After the data processing module extracts and integrates the warning and alert information and sends it to the inventory generation module, staff can understand the warning and alert information from the output inventory, avoiding misoperation and improving the safety and stability of maintenance work.
[0027] The work parameters extracted from the process information database include information on the tools and aviation materials required to perform the process. The data processing module retrieves the storage location, quantity, and replaceable parts of the corresponding tools and aviation materials from the aviation material information database based on the tool and aviation material information.
[0028] The data processing module retrieves the specific torque requirements for each work process based on the work information sent by the information identification module and the work parameters in the data collection module. It then summarizes these torque requirements into the work parameters and sends them to the list output module. The Aircraft Maintenance Manual (AMM) clearly specifies the torque requirements for each maintenance task. During operation, the data processing module retrieves the torque information corresponding to the maintenance task and sends it to the list output module. This allows staff to directly access the torque requirements for maintenance work through the work list, improving the standardization of aircraft maintenance work.
[0029] The work list generation module summarizes the received work parameters to generate a work list and sends it to the staff. The module includes a remote information transmission unit and a work list output unit; the remote information transmission unit wirelessly transmits the work list to the control center, and the work list output unit converts the work list into a visual signal. Staff can adjust the work list according to work needs, modifying the program content within the generation module to suit the output requirements.
[0030] The aircraft maintenance production preparation auxiliary system provided by this invention can identify the content of a plan, retrieve the process details based on the identified information, organize them into a work list, and send it to the staff. The specific operation process of this system is as follows: Step 1: Staff connect the data collection module to the storage medium containing the aircraft maintenance manual and collect the information from the manual.
[0031] Step 2: The information recognition module identifies the on-site work card information and aircraft model information. After recognizing the solution content, the aircraft recognition unit and the work card recognition unit compare it with the information collected in the data collection module and select the matching aircraft model and work card number.
[0032] Step 3: The data processing module, based on the identification and judgment results of the information identification module, retrieves the corresponding process information and the tool and aircraft material information used in the maintenance work from the data collection module. After summarizing the retrieved data, it sends it to the list generation module.
[0033] Step 4: The list generation module integrates and processes the information sent by the data processing module, summarizes it into a production list according to the set program, and sends the production list to the staff.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
