A solution of heat treatment process design system for wind power bolts based on case and rule fusion reasoning is proposed. Secondly, the key technology of heat treatment process design system is analyzed. By classifying the knowledge of heat treatment process, the representation method of heat treatment process example is put forward, and the typical process example is extracted from the heat treatment process rule, and the data storage structure of the example and rule is unified. Through fusion reasoning, similar cases or typical cases are obtained to complete the new case design. Multi-layer retrieval mechanism is used in the retrieval of heat treatment process cases. The method of determining local feature weights of process examples and the calculation formula of feature similarity are introduced in detail. Thirdly, using the theory of software engineering, the overall design, detailed design and system implementation of the system are carried out. According to the function of heat treatment process planning system, this system mainly includes five modules: basic data management, data acquisition and cleaning, heat treatment process planning, history process analysis, system management, etc. The main function modules such as data acquisition and cleaning and heat treatment process design are analyzed in detail. In this paper, the interface layer, business logic layer and data access layer are used to design the three-tier architecture system, and the object oriented encapsulation is realized with the help of entities, and the dependency between layers is reduced, which is beneficial to the expansion of the platform. Facilitate platform maintenance and integration with other systems. Based on Visual Studio and ASP.NET language, the three-layer structure and entity data model are established to realize the heat treatment process design system for wind power bolts. Finally, the system test and application are carried out according to the customer's requirements to meet the expected requirements. The application of the system fully reuses the production experience of historical heat treatment, improves the efficiency of process design and the accuracy of process parameters, improves the quality level of wind power bolt products, and solves the difficult problems in heat treatment process design of wind power bolts. The system studied in this paper has good engineering application value not only for heat treatment process design, but also for the quality control of high strength bolt products, as well as for manufacturing enterprises with relatively complete historical process data.
