Description

Technical Field

[0001] The present invention relates to the technical field of component control, and in particular to a component graded selection control method based on aviation applications. Background Art

[0002] The selection and control of components is the foundation of the quality, reliability, safety, economy and security of aviation products. Its position in the aviation field has leapt from basic technology to core technology. Aviation models carry out the selection and control of components in accordance with the "Management Requirements for the Selection of Electronic Components". Based on this standard, aviation model users use a unified component quality grade as the baseline for selection control. With the development of aviation model technology, this component selection and control method can no longer meet the existing aviation model's demand for component selection. Specifically, there are the following problems:

[0003] 1. The existing selection control method uses the same component quality grade as the baseline to control the selection of components for the entire model. However, different parts of the same model have different selection requirements for components, resulting in the failure to consider the differentiated selection needs in different application scenarios, reducing the rationality of component selection.

[0004] 2. The existing selection control method still uses the seven special levels as the selection control baseline, resulting in a lack of basis for the selection of low-cost components and reducing the economic efficiency of component selection.

[0005] 3. The existing selection control method remains at the component dimension, and selection control is carried out based on the component indicators themselves, such as the component supply cycle and failure rate. It lacks selection control of components from the perspective of aviation models and aviation equipment, resulting in the inability of model users to manage component selection control in detail. Summary of the invention

[0006] In view of this, in response to the differentiated selection needs of aviation components and the detailed management requirements of model users for components, the embodiments of the present application provide a component hierarchical selection control method based on aviation applications, which realizes hierarchical management of components of the same aviation model and different parts, and meets the component selection needs in different application scenarios.

[0007] The embodiment of the present application provides the following technical solution: a component classification selection control method based on aviation applications, comprising the following steps:

[0008] S100: Clarify the selection requirements of target components according to their application scenarios;

[0009] S200: Determine the correlation between the selection requirements and the main influencing factors of the target component selection control, and based on the correlation, extract the main influencing factors of the model dimension, the equipment dimension and the target component dimension;

[0010] S300: Establishing a selection control level classification model based on the main influencing factors;

[0011] S400: Based on the model, a selection control level is obtained, and target component selection control requirements under each selection control level are formulated;

[0012] S500: Perform target component selection control according to target component selection control requirements at each selection control level.

[0013] According to an embodiment of the present application, the target component selection requirements include functional performance requirements, economic requirements, reliability requirements, quality assurance requirements, and raw material production level requirements for the components.

[0014] According to an embodiment of the present application, in step S200, the correlation between the selection requirement and the main influencing factors of the target component selection control is determined, and based on the correlation, the main influencing factors of the model dimension, the device dimension and the target component dimension are extracted, including:

[0015] S201: Extract the main influencing factors of the model dimension;

[0016] S202: extracting the main influencing factors of the equipment dimension;

[0017] S203: extracting the main influencing factors of the target component dimension;

[0018] S204: Clarify the definitions and classification of the main influencing factors in the model dimension, equipment dimension and target component dimension.

[0019] According to an embodiment of the present application, the step S300 of establishing a selection control level classification model based on the main influencing factors includes:

[0020] S301: Define the selection control level to reflect the safety level of components used in aviation applications;

[0021] S302: Establish a relationship matrix between the main influencing factors and the selected control levels.

[0022] According to an embodiment of the present application, in step S400, based on the model, a selection control level is obtained, and target component selection control requirements under each selection control level are formulated, including:

[0023] The quality grade standards of various categories of components are sorted out to obtain a quality grade relationship table. Based on the quality grade relationship table, the lower limits of the quality grades of components for each selection control grade are formulated to form a relationship matrix between the selection control grade and the quality grades of various components.

[0024] According to an embodiment of the present application, in step S500, component selection control work is carried out according to the component selection control requirements under each selection control level, and the lower limit of the quality grade specified for each selection control level is used as the basis for grading the selection control components for aviation models to meet the differentiated needs of aviation models for components.

[0025] Compared with the prior art, the beneficial effects that can be achieved by at least one of the above technical solutions adopted in the embodiments of this specification include at least: the component hierarchical selection control method proposed in the embodiments of the present invention can meet the model user's demand for detailed management of components, and realize the control of component selection from the model dimension, equipment dimension and component dimension. And different from the traditional method of controlling the selection of components with a unified quality grade baseline, the embodiment of the present invention establishes a component selection control grade division model, clarifies the component selection control baseline of each level, realizes the hierarchical management of components of the same aviation model and different parts, meets the component selection needs in different application scenarios, provides guidance for reasonable COTS devices, and is conducive to reducing the cost of aviation models.

[0036] The embodiment of the present invention mainly proposes a component hierarchical selection control method based on aviation applications.

[0037] like Figure 1 As shown, a method for controlling the hierarchical selection of components based on aviation applications according to an embodiment of the present invention comprises the following steps:

[0038] S100: Analyze the selection requirements of components for a certain aviation model, including: functional performance requirements, economic requirements, reliability requirements, quality assurance requirements, and domestic production requirements for components, as shown in Table 1.

[0039] Table 1 Requirements for the selection of components and specific analysis items for aviation models

[0040] Selection requirements Specific analysis items Functional performance requirements Component function performance indicators Economic needs Component cost, assembly process, and integration Reliability requirements Reliability allocation index of the equipment where the components are located Quality assurance requirements Quality grade of components Domestic demand Qualifications of component manufacturers, sources of raw materials for components, etc.

[0041] S200: sorting out the correlation between the selection requirements and the main influencing factors of component selection control, and based on the correlation, extracting the main influencing factors of model dimension, equipment dimension and component dimension. The specific steps include:

[0042] S201: Extract the main influencing factors of the model dimension, including: application environment level.

[0043] S202: Extracting the main influencing factors of the equipment dimension, including: equipment importance.

[0044] S203: Extracting the main influencing factors of the component dimension, including: component importance.

[0045] S204: Clarify the definitions and classification of the main influencing factors of the model dimension, the main influencing factors of the equipment dimension, and the main influencing factors of the component dimension. The definitions and classification of the main influencing factors of the model dimension, the definitions and classification of the main influencing factors of the equipment dimension, and the main influencing factors and classification of the components dimension are shown in Tables 2 to 4 below.

[0051]

[0052] S300: Establish a selection control level classification model based on major influencing factors. The specific steps include:

[0053] S301: Develop the definition of component control level. The definition of component control level (CCL) is: reflecting the safety level of components used in aviation applications. Based on the main influencing factors of a certain aviation model, the component control level is divided into 4 levels, among which CCL1 is the highest level. Components at CCL1 have the highest safety level.

[0054] S302: Establish a relationship matrix between the main influencing factors and the selection control level. Based on the main influencing factors of the equipment dimension: the application environment level (Environment Level, EL), the main influencing factors of the equipment dimension: the equipment importance (Equipment Important Level, EIL) and the main influencing factors of the component dimension: the component importance (Component Important Level, CIL), establish a relationship matrix between the main influencing factors and the selection control level, as shown in Table 5. Table 5 reflects the relationship between the main influencing factors and the selection control level. Among them, EL is the application environment level, EIL is the equipment importance, CIL is the component importance, and CCL is the selection control level. For example: if the application environment level is EL1, the equipment importance is A, and the component importance is CIL1, the selection control level is CCL1.
