Study On Quality Diagnosis Method For Cement Equipment Manufacturing Processing Based On Product Quality Gene

With the rapid development of scientific technology and economic globalization, increasingly fierce market competition, the high-quality products is the key factors for enterprise to improve the core competitiveness. Facing the development opportunity of cement equipment manufacturing industry, improving the quality diagnosis methods in manufacturing process and providing the best quality products is the best way for enterprises to obtain and keep a favorable market position. Some existing quality diagnosis methods and modes, such as statistical analysis modeling, expert diagnosis system, fuzzy diagnosis system, and artificial neural network diagnosis system and so on are used to improve the exactness and convenience of quality diagnosis methods from different sides, respectively.Cement equipment manufacturing industry quality diagnosis analysis is a complicated process with comprehensive factors of product design, process and expertise and so on, which needs to consider the acquisition and refining of product quality information and analyse the relevance between the quality information. At present, genetic engineering technology has been widely used in design and manufacturing fields, this study further expands its application, and it is used in the quality diagnosis of manufacturing process. The product quality gene quality diagnosis model is putting forward to achieve the purpose of quality diagnosis through designing, storing, collecting product quality gene code, analysing heredity and variation process of quality gene, optimizing the quality diagnosis process. This study analyzes the quality diagnosis methods in cement equipment product processing from the following aspects:(1) Product quality genetic model is putted forward through analyzing the origin of product quality gene and the composition of product quality gene.The product quality gene (PQG-Code) coding method and product quality gene XML storage modes is putted forward combined with the complexity of cement equipment processing enterprise quality information.The product quality gene coding method is analysed in one enterprise.(2) Analyzing the formation and evolution of cement equipment product quality gene and the testing process of cement equipment product. Dissecting various kinds of heredity and variation of product quality gene and analyzing the instance; Cement equipment product quality gene diagnostic model is putted forward by the characteristics of product heredity and variation.(3) According to the quality gene diagnostic model, the definition of quality gene similarity is putted forward, and also quality diagnosis process based on quality gene similarity is analysed, that is whether the quality is normal or not can be judged by the given threshold and the similarity between the detected product quality gene and case gene of product quality genetic diagnosis knowledge base.(4) The Demand analysis and general structure of quality gene diagnosis system based on the product quality gene is studied, and each module of quality diagnosis is developed by asp.net (C#) and SQL Server2005, and finally it is used in a cement equipment processing enterprise in Tangshan and achieves good effect.Finally, the text summarizes the research work, analyze the deficiencies, and prospect follow-up study subjects.
