[0027] Another object of the present invention is to provide an intelligent management method for aviation maintenance tools, which adopts the above management system and includes the following processes:

[0028] A1. Tool library establishment

[0029] First, the system administrator starts to build the tool library: it involves comprehensive and accurate entry or import of detailed information on various aircraft maintenance tools. For each tool, its basic information such as tool name, model, specification, manufacturer, unique identification number, etc. must be accurately recorded in the system; at the same time, it is also necessary to enter the tool's technical parameters, applicable models, inventory quantity, storage location key data, which will constitute the basic data architecture of the tool library and provide solid data support for subsequent maintenance task allocation and tool management. For example, when entering the information of an aviation wrench, it is necessary not only to clarify its size specifications, torque range and other technical indicators, but also to record its specific shelf location in the tool library and the current inventory quantity to ensure that it can be quickly located and deployed when needed.

[0030] A2. Establishment of maintenance tasks

[0031] The administrator carefully creates specific maintenance tasks in the intelligent management system according to the aircraft maintenance plan and actual needs. In the process of creating tasks, the administrator initially screens and associates the tools and equipment that may be needed from the tool library according to the nature and requirements of the tasks, and establishes a preliminary connection between the tasks and the tools. At the same time, for specific maintenance tasks, the administrator creates a corresponding maintenance team and associates the team members with the tasks, clarifying the responsibilities and division of labor of each member. Finally, through the notification function of the system, the detailed information of the maintenance task, the list of required tools, and the task allocation of the maintenance team are released to the relevant personnel in a clear and concise manner, ensuring that each member can understand their tasks and responsibilities in a timely and accurate manner, and be fully prepared for subsequent maintenance work.

[0032] A3. Task dispatch and receipt

[0033] After the maintenance task is released, the system automatically dispatches the task to the corresponding maintenance team; the maintenance team members log in to the intelligent management system and check the detailed maintenance task content in the personal task interface, including key information such as task description, technical requirements, and estimated completion time; after carefully checking the preliminary associated tool list, team members submit a request through the system's additional tool request function based on the actual maintenance situation, if they find that other unassociated tools are needed, and specify the name, model, and reason for the request of the required tools; after receiving the request, the system will process it according to the established approval process to ensure the reasonable deployment and efficient use of tools;

[0034] A4. Tool lending

[0035] When the maintenance team's tool application request is approved, team members can go through the tool lending procedures in the intelligent management system. By manually selecting the tool to be borrowed and taking out the corresponding tool in the system, the system will automatically record the tool's borrowing time, borrower, borrowing purpose and other information, and update the inventory status in the tool library. At the same time, the system will generate corresponding borrowing records for subsequent tracking and management. During the borrowing process, the system will also check the status of the tool, such as whether it is in a usable state, whether the calibration validity period has expired, etc., to ensure that the borrowed tool can be used normally and ensure the smooth progress of maintenance work.

[0036] A5. Task Execution

[0037] After receiving the required tools, the maintenance team officially started the maintenance task. Before the operation started, in accordance with the standard operating procedures for aviation maintenance, the team members used RFID handheld devices to conduct strict "three counts" of the tools, namely, counts before work, counts when the workplace was transferred, and counts after the work was completed. The system automatically records the information of each count to ensure that the number and status of the tools are accurate and prevent the tools from being left on the aircraft or lost during the operation. At the same time, with the help of the positioning module of the handheld terminal, the system records the operation trajectory of the maintenance personnel in real time, including the stay time and movement path in different parts of the aircraft, and provides data support for the traceability and optimization of the maintenance process. During the operation, if there are abnormal situations such as tool damage, mismatch with the task, and new potential faults in the aircraft, the team members will promptly feedback the problem to the administrator and relevant technical personnel through the system's abnormal feedback function, and describe in detail the specific manifestations, location and possible impact of the abnormal situation, so as to take timely measures to solve the problem and ensure the safety and quality of the maintenance work.

[0038] A6. Tool Search

[0039] If a tool is found missing during the inventory, the team members will immediately start the tool search process; the mobile terminal system will display the previously recorded operation track records and possible storage locations, providing clues and guidance for finding the lost tools. At the same time, the RFID scanning and positioning module will be started to scan and locate the lost tool tags, helping the maintenance personnel to find the lost tools as soon as possible and reduce the impact of the lost tools on subsequent maintenance work;

[0040] A7. Tool return

[0041] When the maintenance task is completed, the maintenance team will first count the tools again, and return the tools after confirming that they are correct; after returning the tools to their original locations one by one according to the borrowing information, the return completion status is updated through the RFID handheld system, and the server-side system will initiate an inventory command to the smart shelf to review the tool status. After the tool information is verified to be correct, the tool return time, status and other information are automatically recorded and the inventory status is updated to complete the tool return process, and the operation log of this maintenance task is fully saved; the operation log includes detailed tool borrowing and returning records, recording the borrowing and returning time, borrower, tool status and other information of each tool; accurate operation trajectory records, showing the action route and operation position of the maintenance personnel during the entire maintenance process; and complete abnormal feedback records, covering all abnormal situations found during the maintenance process, feedback time, handling measures and results; these rich and detailed operation logs will be stored in the system as important historical data, providing a strong basis for subsequent maintenance work evaluation, tool management optimization and quality traceability.

[0042] A8. Tool maintenance

[0043] The administrator regularly performs maintenance work on the tools in the tool library, including cleaning, calibration, repair and replacement of the tools. During maintenance, the system records in detail the time, content, operator and post-maintenance status of each maintenance work. If abnormal situations such as tool damage or calibration failure occur during maintenance, the system will promptly provide abnormal feedback and wait for further instructions from the inspector. Through tool maintenance and recording, the health status of the tools can be timely grasped, and tools that need to be repaired or replaced can be arranged in advance to ensure that the tools are always in good working condition, providing reliable guarantee for the smooth progress of aviation maintenance work. At the same time, it also helps to analyze the service life and failure patterns of tools, and provide data support for optimizing tool procurement and inventory management.

[0044] A9. Prosecutor's Review

[0045] The inspector logs in to the browser client, handles the abnormal situations reported by the administrator in a timely manner and reviews all abnormal feedback records; analyzes the key factors such as the cause, type, and frequency of occurrence of abnormal situations, and generates detailed statistical reports based on these data; the statistical reports will display the distribution of abnormal situations, trend changes, and the degree of impact on maintenance work in the form of intuitive charts and data, providing decision support for management; at the same time, the inspector writes a detailed review report based on the statistical analysis results, and if necessary, publishes an announcement through the system to convey the results of the handling of abnormal situations, improvement measures, and subsequent precautions to all maintenance personnel and relevant managers, so as to promote experience sharing and continuous improvement of the entire maintenance team, and continuously improve the quality and efficiency of aviation maintenance work.

[0046] The beneficial effects of the present invention are:

[0047] The present invention provides an aircraft maintenance tool intelligent management system, which realizes the construction and deployment of the hardware settings and software facilities of the aircraft maintenance tool intelligent management system by using program development technology, computer network technology, and RFID identification and positioning technology, realizes the intelligent management of the entire life cycle of aircraft maintenance tools, simplifies the business processes related to aircraft maintenance tools, improves the efficiency of tool management, strengthens the supervision of the maintenance operation process, and improves the tool abnormality management guarantee mechanism.

9. An intelligent management method for aviation maintenance tools, using any management system of claims 1 to 8, comprising the following process: A1. Tool library establishment First, the system administrator starts to build the tool library: This involves comprehensive and accurate entry or import of detailed information on various aircraft maintenance tools. For each tool, its basic information must be accurately recorded in the system. At the same time, it is also necessary to enter the tool's technical parameters, applicable aircraft models, inventory quantity, and storage location key data. This information will form the basic data architecture of the tool library and provide solid data support for subsequent maintenance task allocation and tool management. A2. Establishment of maintenance tasks The administrator carefully creates specific maintenance tasks in the intelligent management system according to the aircraft maintenance plan and actual needs. In the process of creating tasks, the administrator initially screens and associates the tools and equipment that may be needed from the tool library according to the nature and requirements of the tasks, and establishes a preliminary connection between the tasks and the tools. At the same time, for specific maintenance tasks, the administrator creates a corresponding maintenance team and associates the team members with the tasks, clarifying the responsibilities and division of labor of each member. Finally, through the notification function of the system, the detailed information of the maintenance task, the list of required tools, and the task allocation of the maintenance team are released to the relevant personnel in a clear and concise manner, ensuring that each member can understand their tasks and responsibilities in a timely and accurate manner, and be fully prepared for subsequent maintenance work. A3. Task dispatch and receipt After the maintenance task is released, the system automatically dispatches the task to the corresponding maintenance team; the maintenance team members log in to the intelligent management system and check the detailed maintenance task content in the personal task interface; after carefully checking the preliminary associated tool list, the team members find that other unassociated tools are needed according to the actual maintenance situation, and submit a request through the system's additional tool request function, detailing the information of the required tools; after receiving the request, the system will process it according to the established approval process to ensure the reasonable deployment and efficient use of tools; A4. Tool lending When the maintenance team's tool application request is approved, team members can go through the tool lending procedures in the intelligent management system. By manually selecting the tool to be lent and taking out the corresponding tool in the system, the system will automatically record the tool's lending time, borrower, borrowing purpose and other information, and update the inventory status in the tool library. At the same time, the system will generate corresponding lending records for subsequent tracking and management. During the lending process, the system will also check the status of the tool to ensure that the borrowed tool can be used normally and ensure the smooth progress of maintenance work. A5. Task Execution After receiving the required tools, the maintenance team officially started the maintenance task. Before the operation started, in accordance with the standard operating procedures for aviation maintenance, the team members used RFID handheld devices to strictly "check the three counts" of the tools, namely, check before work, check when the workplace was transferred, and check after work. The system automatically recorded the information of each check to ensure the accuracy of the number and status of the tools, and prevent the tools from being left on the aircraft or lost during the operation. At the same time, with the help of the positioning module of the handheld terminal, the system recorded the operation trajectory of the maintenance personnel in real time, including the stay time and movement path in different parts of the aircraft, and provided data support for the traceability and optimization of the maintenance process. During the operation, if the tools were damaged, did not match the tasks, or new hidden faults were found in the aircraft, the team members would promptly feedback the problems to the administrators and relevant technical personnel through the abnormal feedback function of the system, and describe in detail the specific manifestations, location and possible impact of the abnormal situation, so as to take timely measures to solve the problems and ensure the safety and quality of the maintenance work. A6. Tool Search If a tool is found to be missing during the inventory, team members will immediately start the tool search process; The mobile terminal system will display the previously recorded operation track records and possible storage location information to provide clues and guidance for finding lost tools. At the same time, the RFID scanning and positioning module will be activated to scan and locate the lost tool tags, helping maintenance personnel to find the lost tools as soon as possible and reduce the impact of tool loss on subsequent maintenance work. A7. Tool return When the maintenance task is completed, the maintenance team will first count the tools again, and return the tools after confirming that they are correct; after returning the tools one by one to their original locations according to the borrowing information, the return completion status is updated through the RFID handheld system, and the server-side system will initiate an inventory command to the smart shelf to review the tool status. After the tool information is verified to be correct, the tool return time and status information are automatically recorded and the inventory status is updated to complete the tool return process, and the operation log of this maintenance task is fully saved; the operation log includes detailed tool borrowing and returning records, recording the borrowing and returning time, borrower, and tool status information of each tool; accurate operation trajectory records show the action route and operation position of the maintenance personnel during the entire maintenance process; And complete abnormal feedback records, covering all abnormal situations found during the maintenance process, feedback time, handling measures and results; A8. Tool maintenance The administrator regularly performs maintenance work on the tools in the tool library, including cleaning, calibration, repair and replacement of the tools. During maintenance, the system records in detail the time, content, operator and post-maintenance status of each maintenance work. If the tool is damaged or the calibration fails during maintenance, the system will promptly provide abnormal feedback and wait for further instructions from the inspector. A9. Prosecutor's Review The inspector logs in to the browser client, handles the abnormal situations reported by the administrator in a timely manner and reviews all abnormal feedback records; analyzes the causes, types, and key factors of the abnormal situations, and generates detailed statistical reports based on these data; the statistical reports will display the distribution of abnormal situations, trend changes, and the degree of impact on maintenance work in the form of intuitive charts and data, providing decision support for management; at the same time, the inspector writes a detailed review report based on the statistical analysis results, and if necessary, publishes an announcement through the system to convey the results of the abnormal situation handling, improvement measures, and subsequent precautions to all maintenance personnel and relevant management personnel.
