Description

Technical Field

[0001] The present invention relates to the field of civil aviation, and in particular to a method for generating a structured document of a PMMEL (i.e., a Master Minimum Equipment List Recommendation). Background Art

[0002] The minimum equipment list (MEL, full name Minimum Equipment List) is a list of parts that can enable an aircraft to fly with a reasonable fault. Using MEL on the route is the most effective way to ensure the balance between aircraft safety and economy, and can improve the economy and market competitiveness of the aircraft. The basis for aircraft carriers to formulate MEL is the master minimum equipment list (MMEL, full name Master Minimum Equipment List). MEL should comply with the restrictions of MMEL or be more stringent than it. MMEL is determined based on the Master Minimum Equipment List Recommendation (PMMEL, full name Preliminary Master Minimum Equipment List) submitted by aircraft manufacturers to the Civil Aviation Administration for review and approval. PMMEL mainly consists of two parts: MMEL recommended project information and analysis materials: MMEL is composed of MMEL recommended project information that has been reviewed and approved by the authority, and the analysis materials are used to prove that the MMEL recommended project information is reasonable, accurate and reliable.

[0003] At present, the main standards that have guiding significance for technical publications in the field of civil aviation include S1000D and ATA2300. Among them, the compilation and compilation management and publishing platform based on S1000D has been widely used in maintenance technical publications, but its applicability to flight operation manuals is not high. ATA2300 aims to guide the compilation and content specification of flight operation technical publications, but there are deficiencies in the current application cases and platform support. PMMEL is a flight operation technical publication. Each aviation manufacturer generally adopts its own corporate standards and uses methods such as WORD to compile it, which cannot well meet the needs of standardized content compilation and convenient data exchange.

[0004] The above reasons result in a lack of solutions that can carry out structured development for PMMEL in the current existing technology, making the management, editing, publishing, and maintenance of PMMEL incompatible with existing standards and existing solutions such as publication management and publishing platforms. This in turn results in the management, editing, publishing, and maintenance of PMMEL requiring a lot of manpower and prone to human errors.

[0005] Therefore, there is an urgent need for a new structured solution for PMMEL compilation to at least partially eliminate the above-mentioned defects of the prior art. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defect that the prior art lacks a structured solution for PMMEL compilation, resulting in the management, editing, publishing, maintenance and other tasks of PMMEL requiring a large amount of manpower and prone to human errors, and proposes a method for generating a structured file of PMMEL.

[0007] The present invention solves the above technical problems by adopting the following technical solutions:

[0008] The present invention provides a method for generating a structured file of a PMMEL, wherein the method comprises the following steps:

[0010] Step 2: Analyze the information elements of multiple main parts contained in PMMEL according to the S1000D standard and the ATA2300 standard to determine the association between the information elements of each main part and the elements based on the S1000D standard and the ATA2300 standard and the information of the data types contained therein;

[0011] Step 3: According to the association relationship determined in step 2, define a SCHEMA structured file template of PMMEL, wherein the SCHEMA structured file template includes several MMEL recommended items as basic units, and splits each MMEL recommended item into at least two types of data modules for mapping information based on the S1000D standard and based on different data types included in the ATA2300 standard;

[0012] Step 4: According to the SCHEMA structured file template of PMMEL defined in step 3, by matching the content of PMMEL and the standard elements based on the S1000D standard and the ATA2300 standard, generate the SCHEMA structured file of PMMEL based on the content of PMMEL, wherein the SCHEMA structured file of PMMEL is suitable for being compatible with files based on the S1000D standard and the ATA2300 standard.

[0013] The SCHEMA structured file of PMMEL generated by the method described above will be able to achieve extensive compatibility with the S1000D standard and the ATA2300 standard in terms of compilation, editing, data import, and management, thereby greatly reducing the manpower cost required for related work based on PMMEL.

[0014] According to some embodiments of the present invention, step one further comprises determining each data module to be composed of an identification and status segment element and a content segment element based on the S1000D standard.

The content segment elements conform to the ATA2300 standard to match the relevant information of the two parts of MMEL recommended project information and analysis materials as the core parts of PMMEL.

[0016] According to some embodiments of the present invention, the information of the identification and status segment elements conforms to the definition in the S1000D standard, and the information of the content segment elements includes the following data types defined in the ATA2300 standard: dispatch release data and certification material data.

[0023] According to some embodiments of the present invention, step three comprises:

[0024] Each MMEL recommended item, which is a basic unit of the SCHEMA structured document template, is split into two types of data modules for mapping dispatch release information and certification material information.

[0025] According to some embodiments of the present invention, the SCHEMA structured file of the PMMEL is a file in XML format.

[0026] According to some embodiments of the present invention, step 4 includes the following sub-steps:

[0027] Establishing an information database of PMMEL based on a relational database, wherein the information database is used to maintain and store the contents of each information item of PMMEL;

[0028] An interactive interface for defining the content of each information item of the PMMEL, wherein the interactive interface is used to input and view the content of each information item of the PMMEL;

BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 The definition of the SCHEMA structured file template of PMMEL in the method for generating the structured file of PMMEL according to the preferred embodiment of the present invention is schematically shown. DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. The following description is exemplary and not intended to limit the present invention. Any other similar situations will also fall within the scope of protection of the present invention. In the following specific description, directional terms, such as "left", "right", "up", "down", "front", "back", etc., are used with reference to the directions described in the accompanying drawings.

[0037] According to a preferred embodiment of the present invention, a method for generating a structured file of a PMMEL comprises the following steps:

[0038] Step 1: According to the S1000D standard and the ATA2300 standard, the content elements applicable to the PMMEL are cut and processed, so as to determine the content elements with the data module as the smallest unit, wherein the data module contains information of at least one data type;

[0039] Step 2: Analyze the information elements of multiple main parts contained in PMMEL according to the S1000D standard and the ATA2300 standard to determine the association between the information elements of each main part and the elements based on the S1000D standard and the ATA2300 standard and the information of the data types contained therein;

[0040] Step 3: According to the association relationship determined in step 2, define a SCHEMA structured file template of PMMEL, wherein the SCHEMA structured file template includes several MMEL recommended items as basic units, and splits each MMEL recommended item into at least two types of data modules for mapping information based on the S1000D standard and based on different data types included in the ATA2300 standard;

[0041] Step 4. According to the SCHEMA structured file template of PMMEL defined in step 3, generate the SCHEMA structured file of PMMEL based on the content of PMMEL by matching the content of PMMEL and the standard elements based on the S1000D standard and the ATA2300 standard. The SCHEMA structured file of PMMEL can be, for example, a file in XML format and is suitable for being compatible with files based on the S1000D standard and the ATA2300 standard.

[0042] It should be understood that the solution proposed in the above-mentioned embodiment of the present invention generally realizes the structuring of PMMEL through the following aspects, namely, analyzing the PMMEL content, using the PMMEL analysis, compilation and verification comprehensive system to generate PMMEL SCHEMA (document in XML format) and complete the PMMEL structuring processing.

[0043] The main technical links (or main steps) of the present invention are supplemented as follows.

[0044] Step 1 is used to analyze standard requirements, that is, to tailor and analyze content elements applicable to PMMEL according to the characteristics of S1000D and ATA2300 standards.

[0045] Step 2 is mainly used for PMMEL content element analysis. That is, according to the content of PMMEL and combined with the requirements of S1000D and ATA2300 standards, the information elements of each part of PMMEL are analyzed to lay the foundation for PMMEL structuring.

[0046] Step 3 is mainly used to define the PMMEL SCHEMA. That is, according to the analysis of PMMEL content elements, determine the correspondence between the PMMEL content elements and the elements in the ATA2300 standard and the S1000D standard, and determine the XML document organization structure of PMMEL.

[0047] In the specific implementation, step 4 can be understood as developing an information generation program based on the XML document organization structure of the PMMEL determined in step 3. For example, according to the defined PMMEL SCHEMA, an information generation program is developed to generate a structured PMMEL that meets the PMMEL content and format requirements by matching the PMMEL content with the ATA2300 and S1000D standard elements.

[0048] The solution proposed in the above-mentioned embodiment of the present invention can be used, for example, to generate structured content of PMMEL about a certain type of aircraft through the above-mentioned technical links in specific implementation. Subsequently, the structured content of PMMEL can be directly imported into some existing publication management and publishing platforms for editing and maintenance (such as platforms developed based on the SD1000 standard), thereby significantly reducing the risk of human errors and standardizing the operational processes of PMMEL writing, editing, and maintenance.

[0049] The SCHEMA structured file of PMMEL generated by the method described above will be able to achieve extensive compatibility with the S1000D standard and the ATA2300 standard in terms of compilation, editing, data import, and management.

[0050] According to some preferred embodiments of the present invention, the step one further comprises:

[0051] Each data module is determined to be composed of identification and status segment elements and content segment elements, and the identification and status segment elements are mapped and associated to the S1000D standard so that the structured construction of PMMEL can be relatively smoothly integrated with the existing technical publication construction environment, and the content segment elements comply with the ATA2300 standard so as to match the two parts of MMEL recommended project information and analysis materials which are the core parts of PMMEL.

[0052] More specifically, the information of the identification and status segment elements conforms to the definition in the S1000D standard, and the information of the content segment elements includes the following data types defined in the ATA2300 standard: dispatch release data and certification material data.

[0053] According to some preferred embodiments of the present invention, the multiple main parts contained in PMMEL include pre-text materials, MMEL recommended project information and analysis materials.

[0054] And, further preferably, the step 2 comprises:

[0055] Associating the pre-textual information with data modules of descriptive data based on the S1000D standard (the pre-textual information includes a cover, a table of contents, and a summary of changes, etc., each of which can be composed of a single data module), wherein each data module contains an identification and status segment element and a content segment element, and the content segment element contains descriptive data information;

[0056] Associating the MMEL recommended item information with information of dispatch release category data based on the ATA2300 standard, wherein the MMEL recommended item information includes MMEL item name and number, repair deadline category, installation quantity, quantity required for dispatch or release, remarks and exceptions; and

[0057] The analysis material is associated with information of certification material data based on the ATA2300 standard, wherein the analysis material includes system description, failure impact, and secondary failure impact.

[0058] According to some preferred embodiments of the present invention, step three comprises:

[0059] Each MMEL recommended item, which is a basic unit of the SCHEMA structured document template, is split into two types of data modules for mapping dispatch release information and certification material information.

[0060] In order to facilitate a clearer understanding of the various main steps of the above-mentioned preferred embodiments of the present invention, the technical processes and / or operation procedures related to each main step are illustrated below.

[0061] First, regarding the analysis of the standard requirements mainly involved in step one, taking into account the characteristics of both S1000D and ATA2300 standards, the overall structured style of PMMEL mainly takes into account the S1000D standard, while the content section adopts the ATA2300 standard to match the core MMEL recommended project information and analysis materials in PMMEL.

[0062] Specifically, the S1000D and ATA2300 standards both adopt the concept of modularization in manual compilation and data management, that is, compiling and storing the content of technical publications in the form of data modules. The S1000D specification provides many rules and suggestions in terms of business rules, information management, data exchange and interactive manual publishing, and has more advantages in the management and publication of publications, while the ATA2300 standard focuses on the technical information management of flight operation technical publications. Its DM "release" and "certificate material" data types are more in line with the technical content requirements of PMMEL, but the status and content of DM in ATA2300 are stored in different files, which are not fully compatible with the platform based on the S1000D standard. Therefore, in the present invention, the technical characteristics of the content of flight operation publications are taken into consideration, and the compatibility with the management and publication of existing technical publications is proposed.

[0063] Secondly, regarding the content element analysis of PMMEL, which is mainly involved in step 2, the information elements of each part of the manual are analyzed based on the content contained in PMMEL and the requirements of ATA2300 and S1000D standards. Among them, the pre-text materials of PMMEL include the cover, directory, change summary, etc., which basically overlap with the pre-text materials of the maintenance manual, so the data module of the "description type" data type based on the S1000D standard, which is consistent with the maintenance manual, can be used. The text part consists of two parts: MMEL recommended project information and analysis materials, which can be associated with the "dispatch release type" data type and "certificate material type" data type in the ATA2300 standard, respectively, so the content segment of PMMEL can be structured based on the ATA2300 standard. Transformation.

[0064] Secondly, for the definition of PMMEL SCHEMA involved in step 3, please refer to Figure 1 The structural framework is shown.

[0065] The analysis unit of PMMEL is the MMEL recommended project, and its content includes MMEL recommended project information and analysis materials. The MMEL recommended project information verified by the analysis materials and approved by the bureau constitutes the MMEL. Combining the standard requirement analysis with the PMMEL content element analysis, considering the compliance with the ATA2300 standard and the conversion relationship when transitioning from PMMEL to MMEL, in the above method of the present invention, each MMEL recommended project can be split into two types of DM in step three, respectively mapping the dispatch release information and the certification material information in the recommended project. The PMMEL SCHEMA defined in this way can better integrate the characteristics of both the ATA2300 standard and the S1000D standard, thereby achieving the purpose of taking both into account.

[0066] According to some preferred embodiments of the present invention, step 4 includes the following sub-steps:

[0067] Establishing an information database of PMMEL based on a relational database, wherein the information database is used to maintain and store the contents of each information item of PMMEL;

[0068] Define an interactive interface for the content of each information item of PMMEL, where the interactive interface is used to enter and view the content of each information item of PMMEL, for example, define the interactive entry and view interface of each information item of PMMEL through the front-end technology composed of HTML, CSS, and JAVASCRIPT programs, and build a unified scheduling interface at the back end through the object-oriented development language C#;

[0069] Determine a mapping relationship between tags (such as HTML tags) in rich text content (such as constructed based on HTML language) containing each information item of PMMEL and standard elements in the SCHEMA structured document template;

[0070] According to the mapping relationship, the rich text content of each information item of PMMEL is automatically generated into the content of the MMEL recommendation item in XML format;

[0071] Based on the content of the MMEL recommended project, the SCHEMA structured file of the PMMEL is generated.

[0072] Based on the above preferred embodiments of the present invention, it is easy to implement the improvement and integration of the existing technical publication system. For example, the SCHEMA structure determined in the method described above can be incorporated into the system of the existing technical publication compilation and publishing platform (for example, the technical publication compilation and publishing platform based on the SD1000 standard) by coding, and the relevant integrity verification and business rule verification can be improved, thereby ensuring that the generated MMEL data module can be incorporated into the platform for unified maintenance and management, and the manual can be published.

[0073] In this case, it is possible to obtain structured content such as the PMMEL of a certain type of aircraft with far less human resources than existing solutions, and directly import it into the existing publication management and publishing platform for editing and maintenance, thereby significantly reducing the risk of human error.

[0074] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that these are only examples, and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and these changes and modifications all fall within the protection scope of the present invention.
