Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0026] like Figure 1 As shown, the embodiment of the present invention provides a CBB pedigree construction method based on aviation airborne products, comprising the following steps:

[0027] Step 1: Create the initial CBB file data divided by functional points through bottom-up summarization and top-down decomposition.

[0028] 1) The bottom-up summary refers to the method of planning the pedigree tree with "professional-functional level CBB-module level CBB". The airborne product survey clarifies the profession, hierarchy and related structure of the department CBB. The professional development of airborne products in the past 5 years is investigated through the interview method and list method, and the statistical survey data is processed to form a product pedigree. It is mainly collected and screened from existing products to identify design results with strong versatility and meet the corresponding maturity requirements, and summarize them to generate CBB.

[0029] 2) The top-down decomposition refers to the integration with product applications. Integrate the product application dimension, decompose from the model product downward, and consider the product's application domain, system / equipment, module, and functional block. Develop a forward development plan from top to bottom; decompose the model product and divide it into levels, sort out the modules and functional blocks in the product, and provide support for CBB development planning and reasonable resource allocation. Save development resources, reduce product complexity and the degree of coupling between subsystems, and improve system integration efficiency; starting from typical products, carry out the first step of sorting out and integrating CBB lineages and products. Unify product levels, standardize naming, and formulate indicators for each level; classify products at each level according to technical requirements.

[0030] Step 2: Determine whether the division, function, and file information of the initial CBB conform to the basic characteristics of CBB.

[0031] The basic features of the CBB include the following:

[0032] 1) Reliability: CBB should be verified and reviewed;

[0033] 2) Reusability: CBB should be universal across multiple different products;

[0034] 3) Independence: CBB provides certain functions and performances to the outside world through standard interfaces;

[0035] 4) Economical: The construction of CBB needs to consider the cost;

[0036] 5) Maturity: CBB needs to meet certain maturity requirements to effectively guide the rapid development of products.

[0037] Step 3: Based on the judgment basis of step 2, those that meet the basic characteristics of CBB are classified according to the level of CBB, professional category, and product functional characteristics.

[0038] 1) The CBB hierarchy refers to the CBB spectrum being divided into component level, function level, module level and equipment level.

[0039] 2) The professional categories and product functional characteristics can be divided into 12 categories, namely, data processing, signal processing, artificial intelligence, graphics and imaging, electromechanical / power control, storage, network bus, interface, power supply, information security, basic software and public.

[0040] Step 4: According to the classification structure of step 3, after a certain CBB review process, various types of CBBs are included and centrally managed.

[0041] The CBB process includes: element review, content review, and compliance review.

[0042] The content of the element review includes: CBB name, function, performance, classification, number, CBB instruction document, CBB application method and applicable conditions.

[0043] The content review includes: the content of the specification, the submitted design drawings, code review, and principle review.

[0044] The compliance review: whether it complies with the relevant standard requirements of the enterprise. Whether the demand, design, development, verification, storage and update of CBB meet the needs.

[0045] 2) The centralized management means that all CBB products are stored and managed in a centralized manner, with dedicated personnel responsible for data statistics, usage evaluation, etc.

[0046] Step 5: CBB is promoted and applied in multiple product design units.

[0047] The CBB family tree is a summary of the CBB of airborne products. After the first version of the family tree is formed, it should be applied as follows:

[0048] 1) During the airborne product requirements analysis phase, the existing CBBs should be effectively utilized by comparing the CBB family tree to improve versatility and reuse rate;

[0049] 2) The module-level CBB and functional-level CBB that have been included in the pedigree tree will be put into CBB storage management after the maturity level reaches level 5.

[0050] 3) Module-level CBBs and functional-level CBBs that are not included in the CBB pedigree tree should be increased annually based on the professional development of airborne products;

[0051] 4) The reuse of module-level CBB in the pedigree tree can be divided into two types: reuse of shelf products and reuse of logic diagrams. In standard products, the size, interface, function and performance of the module are relatively fixed, and the shelf CBB that meets the product requirements can be directly reused; in non-standard products, the logic diagram of CBB can be reused, and configurable design can be performed according to user needs.

[0052] 5) CBBs with low reuse frequency for two consecutive years need to be marked on the pedigree tree.

[0053] Step 6: During the product application process in step 5, each type of CBB is evaluated, and CBB that does not meet the evaluation index is eliminated.

[0054] The evaluation indicators are:

[0055] 1) To promote the full utilization of CBB in airborne products, the reuse of CBB in newly designed airborne products is independently evaluated, and the evaluation results are published in a monthly report. The evaluation data serves as an important reference for the evaluation of the results of CBB system construction and the preparation and update of CBB genealogy planning. The main indicator of CBB evaluation is the CBB reuse rate. There are different reuse rate calculation formulas for functional circuits, software, logic and structural CBB.

[0056] The calculation formula of the CBB reuse rate of the functional circuit is:

[0057]

[0058] The software CBB reuse rate calculation formula is:

[0059]

[0060] The calculation formula of logical CBB multiplexing rate is:

[0061]

[0062] The calculation formula of structural CBB reuse rate is:

[0063]

[0064] 2) CBB reuse frequency, the number of times functional circuit CBB, software CBB, logic CBB and structural CBB are used in different product designs.

[0065] 3) CBB maturity level. Refer to GJB7688 to classify CBB into maturity levels. CBB application components or circuits are subject to risk assessment from the aspects of technology and application history to determine the reliability of CBB in product design.

[0066] Step 7. After step 6, further update the CBB pedigree plan and continuously improve it in the process of practical guidance application.

[0067] The continuous improvement in the process of actual guidance application means that the reused data in step 6 can only be generated in actual application, so there is a mutual feedback relationship between application and pedigree. Through the data feedback in the application process, it will be determined whether the CBB needs further disassembly, whether it needs to be removed from the pedigree, whether it needs to be redesigned, etc., and the practical guidance significance of the pedigree will be iteratively strengthened.

[0068] Step 8: Finally, a multi-level CBB spectrum that can guide practical applications is formed.

[0069] The CBB pedigree tree based on the onboard product of the embodiment of the present invention is as follows: Figure 2 and Figure 3 The CBB pedigree tree is a tree diagram that describes the technical professional composition and hierarchy of the CBB of airborne products. Figure 3 The processed CBB professional survey data of airborne products is divided into four levels according to the CBB pedigree tree, which are:

[0070] The first level is the genealogy category, which is marked by a rounded rectangle in the figure. The specific 12 categories are: 1. Data processing, 2. Signal processing, 3. Artificial intelligence, 4. Graphics and image, 5. Electromechanical / power control, 6. Storage, 7. Network bus, 8. Interface, 9. Power supply, 10. Information security, 12. Public. This category can be adjusted dynamically according to the professional division.

[0071] The second level is the genealogy category, which is marked by an oval in the figure. It refers to the specialty under the category and contains and reflects the module products under the specialty.

[0072] The third level is the genealogy category, which is marked by a hexagon in the figure. This level can be a modular shelf product or a module logic diagram;

[0073] The fourth level is the module-level CBB name, which is determined by each department according to the specifications. The next level is all the function-level CBBs under the module, which should be a complete set.

[0074] A method for constructing a CBB pedigree based on aviation airborne products in an embodiment of the present invention adopts a method that combines bottom-up summarization and top-down decomposition. Bottom-up summary and research clarify the profession, hierarchy and related structure of the department's CBB. Through the visit method and list method, the professional development of airborne products in 5 years is investigated, and the statistical survey data is processed to form a product pedigree, and then collected and screened from existing products to identify design results with strong versatility and meeting the corresponding maturity requirements, and summarize them to generate CBB. Top-down decomposition refers to mutual integration with product applications. Incorporate the product application dimension, consider the product's application domain, system / equipment, module, and functional block. Decompose the product and divide it into levels, sort out the modules and functional blocks in the product, unify the product level, standardize the naming, and formulate indicators for each level; classify products at each level according to technical requirements.

[0075] A method for constructing a CBB pedigree based on aviation airborne products in an embodiment of the present invention adopts an application evaluation feedback mechanism. In order to promote the full utilization of CBB applications in airborne products, an independent evaluation is conducted on the CBB reuse of newly designed airborne products, and the evaluation results are published in a monthly report. The evaluation data serves as an important reference for the evaluation of the results of CBB system construction and the preparation and update of CBB pedigree planning. The main indicator of CBB evaluation is the CBB reuse rate, and there are different reuse rate calculation formulas for functional circuits, software, logic and structural CBB.

[0076] A method for constructing a CBB pedigree based on aviation airborne products in an embodiment of the present invention adopts a multi-level CBB pedigree construction idea. This is reflected in the following two points. First, the professional categories and product functional characteristics are classified into 12 categories, including data processing, signal processing, artificial intelligence, graphics and image, electromechanical / power control, storage, network bus, interface, power supply, information security, basic software, and other categories. Second, the level of CBB refers to the CBB pedigree classifying CBB into component level, function level, module level, and equipment level.

[0077] A method for constructing a CBB pedigree based on aviation airborne products in an embodiment of the present invention is to review the process. The CBB process includes: element review, content review, and compliance review. The content of the element review includes: CBB name, function, performance, classification, number, CBB instruction document, CBB application method and applicable conditions. The content review includes: the content of the manual, the submitted design drawings, code review, and principle review. Compliance review: whether it meets the relevant standard requirements of the enterprise. Whether the demand, design, development, verification, warehousing, and update of CBB meet the needs.

[0078] In response to the product design and development requirements in the aviation field, an embodiment of the present invention provides a pedigree tree construction method based on existing product types and professional directions. This method combines existing product series, professional technical status and future development needs of aviation products to form a pedigree tree construction model with aviation characteristics. Different from the previous fuzzy subjective evaluation method, the embodiment of the present invention adopts a top-down and bottom-up combined analysis method to quantify the use of CBB and improve the reuse level of CBB.

[0079] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
