[0002] In the field of aviation flight testing, the efficiency and accuracy of flight test preparation directly affect the smooth conduct of flight test missions. As the core operational basis for the flight test preparation phase, the design rationality and management efficiency of aircraft maintenance work cards are crucial. Traditional aircraft maintenance work cards mostly use paper-based formats or simple electronic documents, which suffer from problems such as reliance on manual creation, limited types that are difficult to flexibly configure according to flight test missions, low correlation between work cards and basic aircraft information and flight test mission sheets, and inability to track mission execution status in real time.

[0003] In existing technical solutions, electronic work card systems often fail to achieve deep correlation between aircraft basic data, flight test mission data and work card data. Work card task allocation lacks a scientific load balancing mechanism, status feedback during task execution is delayed, and data traceability is difficult. This leads to problems such as task omissions, untimely information transmission, and non-standard operations in flight test preparation, increasing the time cost and error risk of flight test preparation, and making it difficult to meet the needs of efficient and accurate flight test preparation.

It is suitable for aviation flight test support scenarios that require efficient completion of flight test preparation work, accurate control of aircraft preparation status, and smooth flow of troubleshooting tasks, providing technical support for the standardization and efficiency of flight test preparation work.

[0040] The purpose of this invention is to provide a design and support method for electronic work cards for aircraft maintenance in flight test preparation, which solves the problems of weak correlation between aircraft basic data and work cards, low matching efficiency between flight test task sheets and work cards, and limited work card types and configuration flexibility in traditional work card management. This invention enables users to quickly create multiple types of electronic work cards based on basic aircraft information, achieve accurate association between work cards and flight test tasks, and improve the standardization, efficiency and data traceability of aircraft maintenance work card management in the flight test preparation phase.

[0041] Technical architecture: Aircraft maintenance management system framework, data storage and association module, work card creation and configuration engine, task association and workflow component.

[0042] (1) Aircraft Basic Data Preparation and Management Plan Data collection and entry: Supports importing basic aircraft information from data sources or manual entry by users, covering core data such as aircraft model, serial number, and system parameters.

[0043] Full lifecycle management: Provides data update and deletion functions, and realizes the recovery of accidentally deleted data through a data backup mechanism to ensure the integrity and continuity of basic aircraft data.

[0044] Data validation mechanism: Perform format validation and key field verification on the basic aircraft data entered or imported to prevent invalid or erroneous data from entering the system.

[0045] (2) Flight Test Mission Data Preparation and Association Scheme Task creation: Based on basic aircraft information, it supports importing or custom creation of test flight task orders, including key information such as task name, number, and planned time.

[0046] Task management: Provides task editing and deletion functions, ensures task data security through backup and recovery mechanisms, and supports task priority settings.

[0047] Association mapping establishment: Through data association rules, the test flight mission form is bound to the corresponding basic aircraft information to ensure accurate correspondence between mission and aircraft.

[0048] (3) Scheme for Creating and Configuring Electronic Work Cards for Aircraft Maintenance Multiple work card types can be created: Based on the basic information of the aircraft and the requirements of the flight test mission, a variety of preset work card types can be selected, including general inspection, appearance inspection, service preparation, power-on inspection, post-flight inspection, mandatory inspection items, flight release confirmation, missile inspection, pre-test, etc., to meet the needs of different flight test preparation scenarios.

[0049] Work card attribute configuration: Configure basic attributes for each type of electronic work card, such as work card number, applicable aircraft model, corresponding task type, version number, etc., to ensure the uniqueness and identifiability of the work card.

[0050] Task order association configuration: Based on the specific content of the flight test task order, the configured electronic work card is bound to the corresponding task order through association rules to achieve accurate matching between the work card and the task, and ensure accurate use of the work card when the task is executed.

[0051] In other embodiments of this application, the following solutions are provided: (1) Backend data creation and association configuration: Aircraft basic information creation: In the back-end management system, basic aircraft data, including aircraft model, serial number, system configuration parameters and other core information, are entered through forms or templates. The system automatically performs format verification and redundancy removal on the data, generates a unique aircraft identifier and stores it in the database.

[0052] Flight test mission creation: Based on the basic information of the aircraft that has been created, a new flight test mission can be created in the background. Key information such as mission name, unique mission number, and planned start time can be entered. The mission can be linked to the corresponding aircraft identifier by selecting from the drop-down menu to establish a binding relationship between the mission and the aircraft. The mission priority setting and status marking are supported.

[0053] Electronic work card creation and association: Based on the requirements of the test flight mission, select a preset work card template (such as service preparation, power-on check, etc.) in the background to create an electronic work card, and configure attributes such as work card number, applicable aircraft model, and mission details; associate the electronic work card with the corresponding test flight mission through the mission order number to form a hierarchical data association chain of "aircraft-mission order-work card", and the association relationship is synchronized to the system database in real time.

[0054] (2) Pad terminal work card data initialization and flow status synchronization: Basic data is stored locally: The backend system packages basic aircraft information, test flight task data, and preset electronic work card templates according to task relationships and synchronizes them to the local database on the Pad via an encrypted interface. The synchronized data includes basic work card information (type, number, associated task), task details (operation specifications, inspection standards), and flow rules (transferable roles, status switching conditions), and supports offline caching to ensure normal use in environments without network access.

[0055] Real-time synchronization of workflow status: When the electronic work card completes a workflow status change in the background system (e.g., from "pending assignment" to "assigned to mechanic"), a status update command is pushed to the corresponding role's Pad terminal in real time via WebSocket. After receiving the command, the Pad terminal automatically updates the status indicator in its local work card list and notifies the user via a message notification bar that "a new work card is pending processing".

[0056] (3) Permission-based display of work card list on the Pad terminal: Role-based work card filtering: After a user logs in to the Pad, the system automatically reads the current user's role information (such as Mechanic or Quality Inspector) and filters out electronic work cards with a status of "Pending Processing" according to the work card circulation rules. These are then displayed first on the list page. For example, after a Mechanic logs in, only work cards with a status of "Pending Execution" assigned to them are displayed, and after a Quality Inspector logs in, only work cards with a status of "Pending Review" are displayed. Irrelevant work cards are hidden by default.

[0057] Visual indicators for work card status: Work cards in different workflow states adopt differentiated visual designs on the Pad. For example, "Pending execution" work cards are marked with a blue border, "Pending review" work cards display a yellow reminder icon, and "Completed" work cards are marked with a green checkmark, helping users quickly identify the priority of work cards.

[0058] (4) Implementation of the character-based chemical card operation process: Mechanic work card execution operation: Click on the target task card in the "Pending Task Cards" list to enter the details page and see the complete list of task items. You can also select the status of the task items ("Not Started", "In Execution", "Completed") by touch.

[0059] For tasks that require recording results, take photos of the scene using the Pad's camera (automatically compressed and associated with the task), or enter the inspection results using the voice-to-text function. The system saves the operation records to the local machine in real time.

[0060] When an anomaly is detected, click the "Record Anomaly" button, fill in the problem description and preliminary judgment, and the system will automatically generate an anomaly code and associate it with the current work card. After submission, the work card status will be updated to "Pending Review" and transferred to the quality inspector.

[0061] Quality Inspection Employee Card Verification Procedure: View work card details in the "Pending Review" list. You can swipe to view the results of tasks submitted by mechanics, on-site photos, and anomaly records. You can also zoom in to view image details.

[0062] When the review is approved, click the "Review Approved" button and complete the handwritten signature. The work card status will be updated to "Completed". If rectification is required, click "Return for Rectification". After entering the rectification requirements, the work card will automatically be transferred back to the mechanic's "Pending Execution" list, and the original executor will be reminded at the same time.

[0063] Multi-role collaborative operation support: During the work card circulation process, after the preceding role completes its operation, the system automatically pushes the work card to the next role's Pad according to the circulation rules, without manual intervention. For example, after a mechanic submits a "power-on inspection work card," the system automatically transfers it to the quality inspector's review queue.

[0064] The system supports work card forwarding. When the current role cannot handle the work card, the "transfer" function can be used to select another person in the same role to receive the work card. The transfer record is automatically written to the operation log.

[0065] (5) Work card operation record: The entire operation process is recorded: The Pad automatically records all information about the work card operation, including the operator, operation time, task status changes, result entry content and signature information, ensuring that every step of the operation is traceable.

[0066] (6) Work card circulation status feedback and reminders: Real-time feedback on operation results: After each operation is completed, the Pad will provide feedback on the result through a pop-up window or floating prompt, such as "Task item marked as successfully completed" or "Abnormal record has been saved". If the operation fails (such as photo upload timeout), the specific reason and retry button will be displayed.

[0067] Timeout reminder mechanism: For work cards that exceed the planned execution time, a reminder window will pop up on the Pad at regular intervals, and a red timeout mark will be displayed on the list page. At the same time, a message will be pushed to the person in charge to ensure the efficiency of work card circulation.

[0068] (7) Data security and data flow traceability: Local data encryption protection: The work card data, operation records and signature information stored on the Pad are encrypted using the AES encryption algorithm. The temporary cache is automatically cleared after the user logs out to prevent data leakage.

[0069] The workflow is traceable: the backend system records the complete workflow path of the work card, including the receiving time, operation time, and status change nodes for each role. The Pad supports viewing the historical operation records of the current work card through the "Work Log" function to ensure process compliance.

[0070] The above detailed embodiments are a description of the present invention. It should not be considered that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, several simple deductions and substitutions can be made without departing from the concept of the present invention, and all of these should be considered to fall within the protection scope of the present invention.
