[0033] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0034] like Figure 1 As shown, this embodiment provides a technical solution: a complex electronic equipment quality data analysis and evaluation system, including a data layer, a business layer, a presentation layer and an access layer;

[0035] The data layer uses Oracle database software to store different data information. The radar structure digital prototype model library is used to store the digital prototype model of radar equipment. The open port interacts with the product, component and parts quality database to generate a quality data integration model. The radar equipment quality data integration database is the core database of the data layer. On the one hand, the database stores the quality data and quality data integration model of each stage of radar equipment. On the other hand, through customized development, the xBOM information (referring to the BOM information of each stage) is integrated and compared with the new quality data information to diagnose the accuracy and consistency of the new quality data, providing the business layer with the only accurate decision support information.

[0036] The business layer is the core layer of the entire system development. This layer extracts different quality data information for different business objects through business processes such as quality data analysis and verification, design quality assessment, and improved design solutions. The division of this process is related to the various stages of radar equipment research and development and is directly related to the accuracy of data collection.

[0037] The presentation layer publishes the quality data into electronic query manuals that are independent of the software platform, and creates multimedia files such as animation demonstration files through customized tools. The collected quality data is packaged through XML (Extensible Markup Language) and converted into publishable general file information, which is submitted to the system's controllable domain information platform for the access layer to take as needed.

[0038] The access layer is the external embodiment of the digital and integrated advantages of the system. Different visitors, such as users, after-sales departments, design departments, manufacturing departments and qualified suppliers, can extract the quality data information they need according to different access rights, and intuitively display it on their respective terminals in the form of quality data integration models. The quality data information associated with them is communicated through this layer, realizing the continuous feedback and update of quality data between departments within the manufacturing enterprise, and realizing the management of radar equipment quality data and continuous improvement of product quality.

[0039] In this embodiment, a radar equipment quality data information structured analysis method is provided to complete the quality data analysis work in the business layer. The radar equipment quality data system structure analysis method referred to in the present invention mainly studies the acquisition of radar equipment quality data information that can be integrated into the three-dimensional design model based on the research and development stage, analyzes its source, studies the classification method, and then studies the quality data extraction technology of key components, and performs data structure analysis on the extracted quality data information, providing an information basis for constructing a radar equipment quality data integration model.

[0040] The technical route adopted is as follows: First, the quality data sources of radar equipment must be analyzed and classified. The principle diagram of the structured analysis method of radar equipment quality data information is as follows: Figure 2 As shown. Radar equipment quality data information mainly includes radar equipment whole machine quality data information, which refers to the data set of engineering technical parameters that determine and affect the overall quality of radar; radar equipment design process quality data information, which refers to the design process quality indicators of radar components and parts, and the relationship between design process quality and radar whole machine quality; radar equipment manufacturing quality data information, which refers to the parameter set that affects radar whole machine quality control during the radar assembly process, such as the characteristics, tools, fixtures and processes of the assembly line; radar equipment use quality data information, which refers to the data set generated by monitoring the working status of the radar whole machine, subsystems and key components during the use of the radar by the troops; radar equipment maintenance quality data information, which refers to the data set generated during the periodic overhaul and routine minor repair of the radar.

[0041] According to the characteristics of the radar equipment quality data source and the components of the radar equipment itself, the radar equipment quality data can be divided into product quality data information, component quality data information and part quality data information. The data structure analysis is carried out on the quality data sources and quality data categories of different levels of radar equipment. Based on the results of the data structure analysis, a unified data collection rule and information recording template are established. The processed quality data information and the design quality characteristics of the radar equipment are integrated to form design quality data.

[0042] In this embodiment, if Figure 3 As shown, a radar equipment quality data tracking and transmission method based on BOM information association and integration is also provided. The radar equipment quality data tracking and transmission method mainly studies how to track and locate quality data in the product life cycle based on the data of the existing information system within the enterprise, comprehensively equipped with BOM information of the radar equipment life cycle, and takes key design quality characteristics as the core.

[0043] The development process of radar equipment is generally divided into design, manufacturing, use and maintenance stages. As for the expression of quality data in the process, the design stage mainly includes whole-machine-level quality data and design process-level quality data. The input of whole-machine-level quality data is mainly the quantitative expression of user needs, and the CBOM (Customer Bill of Material, user BOM) information is integrated to generate quality goals and whole-machine functional quality factors; through the analysis of radar components, the functional quality factors are converted into structural quality factors.

[0044] The design process-level quality data is generated in the detailed design stage of the radar. Its input mainly comes from the structural quality factors of the whole-machine-level quality data. By integrating EBOM (Engineering Bill of Material, design BOM), PBOM (Planning Bill of Material, process BOM), and ABOM (Assembly Bill of Material, assembly BOM), the structural quality factors are decomposed and optimized, and the quality plan is coordinated and completed. The quality data information at this stage is integrated into the digital prototype model, which is mainly used to support quality control in the downstream manufacturing stage.

[0045] Manufacturing-level quality data is generated during the radar manufacturing stage. Part of its input comes from the quality parameter set of the structure itself determined during the design process stage, and the other part comes from information on the workshop including processing personnel and equipment. Combined with MBOM (Manufacturing Bill of Material), the quality data information generated during radar processing and manufacturing is controlled, analyzed and processed.

[0046] The radar usage and maintenance stage generates usage and maintenance-level quality data, with the quality data when the radar leaves the factory as the initialization information. On this basis, the quality monitoring and quality data recording of the radar during use are mainly carried out by military users. After the quality fault is handled, the comprehensive RBOM (Repair Bill of Material) is used to promptly feedback the quality data change information to the after-sales department of the radar manufacturer through confidential transmission.

[0047] During the design phase of radar equipment, a 3D design model of the radar structure is established using 3D modeling tools. Information such as dimensions, tolerances, annotation requirements, process requirements, surface treatment, heat treatment, etc. is then annotated on the 3D model to generate a digital prototype model of the radar equipment. The digital prototype model will generate different annotation information at different design stages, and these digital prototype models will be uniformly stored in an integrated database.

[0048] Quality data information mainly includes whole machine quality data, design process quality data, manufacturing quality data, use and maintenance quality data. In the research process, the expression of these quality data is divided into four forms, namely attributes, relationships, native features and derived results. The above four forms belong to the expression of quality data and may appear and be applied in each life cycle of radar equipment. Taking the quality data expression of the radar turntable in the design stage as an example, its attributes are "design level accuracy of turntable", "ZHT-A", "important"; the relationship is "loading platform (parent)", "engineering design"; the native features are "strength", "1", "design process level"; the derived results are "strength simulation analysis", "1", "analysis results".

[0049] The quality data of radar equipment at each stage corresponds to the BOM information of each stage. After abstract processing, these quality data are associated with the design quality data to form an integrated model of quality data at each stage. According to the corresponding relationship, they are stored in the integrated database, thus obtaining the radar equipment quality data integrated database.

[0050] In this embodiment, if Figure 4 As shown, a comprehensive evaluation method for the design quality of radar equipment electromechanical system based on fuzzy multi-attribute decision-making is also provided. The main research is on the analysis and verification methods of key design quality characteristics, as well as the weight allocation of multiple key design quality characteristics in the comprehensive evaluation of radar equipment electromechanical system design quality. The comprehensive evaluation value of radar equipment electromechanical system design quality is calculated by weighted calculation, and corresponding standards and specifications are formulated.

[0051] Technical route adopted: Use fuzzy evaluation method to determine the quantitative value of key design quality characteristics, and combine fuzzy hierarchical analysis method to determine the weight distribution between multiple key design quality characteristics. Through the preprocessing of attribute values, calculate the comprehensive evaluation value of radar equipment electromechanical system design quality, which is used to analyze and improve the design. The schematic diagram is as follows Figure 4 shown.

[0052] By extracting the key design quality characteristics (such as accuracy, reliability, weight, etc.) of the radar equipment electromechanical system, and combining it with the design quality evaluation system, the secondary and tertiary evaluation indicators are formulated. By tracing and analyzing the whole-machine-level quality data and design process-level quality data in the radar equipment design stage, the manufacturing-level quality data in the manufacturing stage, and the use-level quality data and maintenance-level quality data in the use and maintenance stage, the quantitative values ​​of each key design quality characteristic are calculated, and the numerical preprocessing such as standardization and normalization is performed. With the help of fuzzy hierarchical analysis method and combined with the radar equipment electromechanical system design quality evaluation indicator system, the weight distribution of each key design quality characteristic of the radar equipment electromechanical system is determined, and weighted calculation is performed with the quantitative values ​​of the key design quality characteristics to obtain the comprehensive evaluation value of the radar equipment electromechanical system design quality, and then the evaluation result analysis and improvement design suggestions are carried out.

[0053] To sum up, the complex electronic equipment quality data analysis and evaluation system in the above-mentioned embodiment takes typical ground high-mobility radar equipment as the research object, and aims at the needs of improved design and quality data system development in complex environments in the development of key models such as large radar equipment and major scientific and technological special systems. It solves the problems of low homology rate of quality data, low information integration, and lack of data support and specifications for design quality evaluation. It breaks through key technologies such as quality data information structuring method, quality data integration modeling method, and quality data analysis and evaluation method. On this basis, it carries out comprehensive evaluation and improved design research on radar design quality, and forms a quality data analysis and evaluation system for radar electromechanical system design, manufacturing and use stages. According to the evaluation results, it guides the improved design of radar electromechanical system to achieve the purpose of improving design quality, reducing maintenance costs, and improving quality control capabilities.

[0054] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
