[0001] The invention belongs to the technical field of aviation manufacturing process planning, and relates to a method for compiling process instructions based on knowledge and application data. Background Art

[0002] In the current assembly manufacturing process, process instructions are generally used for management. With the development of information systems, process instruction files have the ability to be structured, but reference drawings, design documents, related resources, content, common language and other information are still filled in manually. The referenced parts and some process resources still need to be manually edited and entered after identification and confirmation by process personnel. The workload of preparation and verification is large and prone to errors. At the same time, the relevant process knowledge required in the process of process instruction preparation is scattered in the personal computers of each process technician, and most of them still rely on the technical experience of the process technician, resulting in different quality of process instruction content preparation.

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 A business process diagram of a method for compiling process instructions based on process knowledge. DETAILED DESCRIPTION

[0033] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings.

[0034] Combined with Figure 1The method of compiling process instructions based on knowledge and application data is to divide the content of the process instruction compilation into the information to be undertaken (product attribute information), standard information such as resource types required for process compilation, subjective process knowledge information of the compilation content, and information on field application. By establishing knowledge data and application data, they are transferred / shared with process personnel, and the process personnel complete the compilation of process instructions. This method includes the following steps:

[0035] Step 1: Classify and divide the data required for the preparation of process instructions, including the required product attribute information, standard information such as process resource categories, process knowledge information, and actual information for on-site applications.

[0036] Step 2: Establish a data information database

[0037] There is no need to establish a database for product attribute information. This part of information is mainly achieved by establishing an information system, setting information receiving and transmission rules, and implementing process instructions.

[0038] Directly receive product attribute information, including part number, name, size, material grade, weight, version, validity, etc.

[0039] Standard information such as process resources mainly includes process documents, design documents, standard terminology, process equipment, processing equipment, tools, cutting tools, measuring tools, standard record forms, materials, etc. required in the process of preparing process instructions.

[0040] Process knowledge information mainly includes various information such as process standard terms, process flow, process method, process parameters, process template, quota formula, typical process description, etc.

[0041] The actual information of on-site application mainly includes the measurement records of important parts specified in the process instructions, weight records, problem records during the execution process, etc.

[0042] Step 3: Set up information extraction and usage rules

[0043] According to the content of process instruction compilation, set the rules for receiving and extracting product attribute information, set the selection rules of standard information such as process resources and process knowledge information, and formulate the sharing, analysis and use process of actual information for on-site application, so that process personnel can share the above types of information in a timely manner.

[0044] Product attribute information is directly extracted, such as product drawing number, name, edition, number of units, material brand, technical documents cited in the product, etc. This part of the content can be directly inherited and extracted. When the information changes, the process instruction will also receive the changed information. All information retains the process edition content for easy traceability.

[0045] Standard information such as process resources is selected independently in combination with the currently required information when compiling process instruction information, mainly to ensure the correctness and consistency of the selected information. Information on process equipment, equipment, tools, cutting tools, measuring tools, and materials is taken from the independent database, process documents, design documents, etc. are taken from the document database, standard record forms and standard data are taken from the independently established data information database, and the content comes from various relevant top-level standard documents.

[0046] The process knowledge information comes from the empirical data that has been verified and summarized for many years in the process design stage. In the process of compiling process instructions, the existing empirical data is preferred. For personalized data information, after actual verification, collection, analysis and review, it is unified and updated to the process knowledge database, and then shared by various compilers for application. Process knowledge information is classified according to process standard terms, process flow, process method, process parameters, process template, quota formula, typical process, etc., and selected by category during use; the set process template can formulate the process content description standard in advance, and directly quote similar process.

[0047] The actual information of field application mainly comes from the record requirements of process setting, the actual record information of product inspection, and the record information of related issues and treatment measures raised by users during the acceptance process. The compiler can quickly collect relevant information through the system, classify and analyze the information, summarize it according to the links of people, machines, materials, methods, and environment, and use quality analysis tools to formulate targeted error prevention measures to avoid the continued occurrence of subsequent problems.

[0048] Step 4: Start process instruction compilation

[0049] When the process of preparing the business according to the set process instructions is started, the process instruction preparation task is started, and the product inherent attribute information is automatically entered into the corresponding column of the process instruction.

[0050] When compiling process instructions, by selecting the process name in the data information library (for example: part inspection, part positioning, CNC milling, painting), the process instruction compilation system will automatically provide the process method and process standard description, tools used, processing equipment, required basic materials and other information corresponding to the selected process. For the content that needs to be recorded, select the standard template in the data information library, and through the field application information in the data information library, historical measured data will be provided for reference.

[0051] When the content of the process instruction is to be executed according to the requirements of the process file and design file, the corresponding process file and design file number can be selected in the data information library, and the corresponding content can be expressed through a link.

[0052] When the content of the process instruction to be compiled is similar to the original process instruction content in the process instruction compilation system, the process template can be directly selected in the data information library and the difference in content can be modified accordingly.

[0053] The content selected from the data information database has corresponding codes and hyperlinks. Personalized content can be written by yourself without coding, and then the analysis and arrangement of non-standardized information can be carried out based on the coding identification.

[0054] Step 5: Check process instructions

[0055] After the process instruction is compiled, it is necessary to check the instruction, which is done by the process instruction compilation system and manually. The process instruction compilation system can check the information automatically entered and selected from the data information library, and prompt information that does not conform to the rules or is missing. For the information of the process instruction content, if it is selected from the database, the process instruction compilation system can check it, and the manual only needs to verify the content that has not been standardized and not selected from the database. For the selected resources and knowledge, the inspection can be carried out in the form of a summary report.

[0056] Step 6: Review and release of process instructions

[0057] After completing the process instruction preparation, the process personnel initiate the review process through the process instruction preparation system and conduct online review. Each reviewer can view the relevant content and related information in the knowledge base through the link relationship at any time. After the approval is completed, the process instruction preparation system will manage the process instructions in a finalized version. After the approval is completed, the published process instructions will be pushed to the on-site terminal, and the operator can view and execute the process instruction file through the on-site terminal.

[0058] The present invention provides a method for compiling process instructions based on process knowledge and application data. By establishing various types of knowledge data and integrating them into the process instruction compilation process, the data of field application execution can be extracted for data collation and analysis. The compiler can identify improvement points based on feedback information, and solidify the new process knowledge after verification for subsequent instruction compilation. This method can realize efficient and rapid process instruction compilation, ensure accurate compilation of process instruction information, and relatively stable compilation quality.
