[0060] Step S3: Acquire the release operation information generated in the historical shipping maintenance process, store the interactive data between the primary aircraft maintenance data and the release operation information as secondary aircraft maintenance data, and create an index based on the secondary aircraft maintenance data;

[0061] Step S4: When an actual operation of shipping maintenance is generated, the historical flight plan and aircraft scheduling in the first-level aircraft maintenance data are obtained and compared with the actual operation, the time period and work location of the actual operation are determined, and the actual operation is tracked and monitored to generate an operation review list, and the actual operation information flow is automatically saved;

[0062] Step S5: Acquire the actual operation information flow according to the index established by the secondary aircraft maintenance data, generate maintenance review information, compare the maintenance review information with the operation review list, and complete an operation self-check;

[0063] Step S6: Acquire the actual operation information flow according to the index established by the secondary aircraft maintenance data, extract the operator information of the actual operation, and extract the license information in the operator information, analyze the applicability range of the license information, compare whether the maintenance review information falls within the applicability range, and complete a personnel self-check;

[0064] Step S7: Establish an airworthiness assessment based on the operation self-inspection and personnel self-inspection, and generate a release record.

[0065] In some embodiments of the present application, in step S1, a plurality of information flow nodes generated in the historical shipping maintenance process are obtained, and first-level aircraft maintenance data is obtained according to each information flow node, including:

[0066] Extract aircraft data fields, including aircraft model and component list, parts list, standard parts list, and non-standard parts list corresponding to the aircraft model;

[0067] Extracting maintenance data fields, including extracting maintenance activity descriptors from information flow nodes involving routine inspection, periodic inspection, troubleshooting, repair and replacement, system calibration and adjustment, cleaning and maintenance, component inspection and maintenance, aircraft structure inspection, aircraft system update and upgrade;

[0068] Extract the maintenance personnel data fields, including the maintenance personnel responsible for maintenance activities, use a nested dictionary structure to construct maintenance personnel groups, define a unique key for each maintenance personnel group in the internal dictionary, use the member list of each maintenance personnel group as the value of the corresponding key, and set the preset weight for each maintenance personnel group as the key in the external dictionary.

[0069] Specifically, multiple information flow nodes in the historical shipping maintenance process are extracted, and the first-level aircraft maintenance data, including aircraft data fields, maintenance data fields, and flight maintenance personnel data fields, are obtained according to each information flow node. The following steps are followed:

[0070] Traverse the information flow nodes in the historical shipping maintenance process, including:

[0071] Obtain aircraft data fields of each information flow node, including aircraft model and component list, parts list, standard parts list and non-standard parts list corresponding to the aircraft model;

[0072] The maintenance data fields of each information flow node are obtained, including maintenance activity descriptors involving daily inspection, periodic inspection, troubleshooting, repair and replacement, system calibration and adjustment, cleaning and maintenance, component inspection and maintenance, aircraft structure inspection, aircraft system update and upgrade, etc.

[0073] Get the data field of the maintenance personnel responsible for the maintenance activities in each information flow node.

[0074] Use a nested dictionary structure to build a group of flight maintenance personnel, including:

[0075] In the internal dictionary, define a unique key for each maintenance personnel group.

[0076] The member list of each flight maintenance personnel group is used as the value of the corresponding key;

[0077] In the external dictionary, preset weight settings are set for each group of flight maintenance personnel, including:

[0078] Use the unique key of the flight maintenance personnel group as the key of the external dictionary;

[0079] Set the weight of each group of flight maintenance personnel to the value of the corresponding key.

[0080] Specifically, the component list describes the major components or modules of the aircraft, including the main structures, systems and devices of the aircraft, such as wings, fuselage, engines, landing gear, doors, etc.;

[0081] A parts list is a detailed list of the parts contained in each assembly. A parts list is a list of specific parts or components contained in each assembly on an aircraft. It describes in detail the parts contained in each assembly of the aircraft, such as the turbine blades, fuel pumps, ignition systems, etc. of an aircraft engine. A parts list is very important in maintaining and repairing an aircraft to determine the specific parts that need to be replaced or repaired.

[0082] The standard parts list is a list of standardized parts used on the aircraft. The standard parts list lists the standardized parts used on the aircraft. Standard parts are parts that have been certified and standardized. They are usually universal, interchangeable, and comply with industry standards and specifications.

[0083] The non-standard parts list is a list of non-standard parts used on the aircraft. Non-standard parts refer to parts customized according to specific requirements or designs, which cannot be directly replaced or used on other aircraft. The non-standard parts list describes the types, specifications and quantities of non-standard parts used on the aircraft, such as specific models of sensors, controllers, avionics systems, etc. Managing non-standard parts requires more customization and supply chain management because they may require special design, manufacturing and maintenance;

[0084] In summary, these lists play an important role in the aircraft manufacturing, maintenance and repair process, helping to manage the aircraft's makeup and the use of its parts.

[0085] It can be understood that by processing the above data and storing the aircraft maintenance data, the accuracy, completeness and storage efficiency of the aircraft maintenance data can be guaranteed, providing airlines and flight maintenance personnel with better maintenance management and decision-making basis.

[0086] In some embodiments of the present application, in step S2, based on the extracted regional information, the boundaries of the operation and maintenance areas are determined based on geographical location, administrative divisions, and airport / airport factors;

[0087] Determine the number of physical nodes or servers corresponding to each operation and maintenance area based on the data volume and preset access mode. Determine the number and scale of nodes based on the data volume and access load requirements. Redundantly back up the data in each operation and maintenance area to prevent single point failures.

[0088] In each operation and maintenance area, the first-level aircraft maintenance data is sorted in chronological order according to the extracted time information.

[0089] Specifically, the data is sorted in chronological order using a sorting operation in the MapReduce framework. It can be understood that the MapReduce framework is a programming model and computing framework for large-scale data processing, which decomposes data processing tasks into two stages: mapping and reduction.

[0090] In the mapping phase, the input data is divided into several data blocks, each of which is processed by a mapping function, which converts the input data into key-value pairs and generates intermediate results.

[0091] In the reduction phase, the intermediate results are processed by the reduction function to generate the final output result. The reduction function merges and processes the intermediate results with the same key to get the final result.

[0092] The core idea of ​​the MapReduce framework is parallel processing and distributed computing. It can execute mapping and reduction tasks in parallel in large-scale clusters to improve the efficiency and performance of data processing.

[0093] Specifically, in this embodiment, the MapReduce framework is used. In the mapping phase, each computing node splits the input data into key-value pairs, and maps the data into key-value pairs according to the time field, where the key is the time field and the value is the corresponding data; then, in the reduction phase, the framework passes the data pairs with the same time to the reduction function. In the reduction function, the built-in sorting algorithm (such as quick sort or merge sort) or a custom sorting logic can be used to sort the data with different times. Specifically, the data is sorted in ascending or descending order according to the time field; finally, the sorted results are output.

[0094] In summary, the advantages of using the MapReduce framework for chronological sorting include parallel processing, scalability, fault tolerance, flexibility, and ease of use, which provides an efficient and reliable sorting solution in large-scale data processing scenarios.

[0109] When the type in the license information is the same as the type of the airworthy aircraft maintenance license in the operation and maintenance area, and the level in the extracted license information is higher than the level of the airworthy aircraft maintenance license in the operation and maintenance area, a self-inspection pass is recorded.
