[Abstract]:With the rapid development of manufacturing technology, people pay more and more attention to the quality of products. At this stage, many manufacturing enterprises attach great importance to the quality assurance activities in the process of production. However, the focus of attention is not limited to the conformity or volatility of product quality. The guarantee of equipment precision in manufacturing process has been closely related to product quality. The guarantee of equipment precision has become a research hotspot. While monitoring the fluctuation of product quality characteristic parameters, real-time monitoring of manufacturing equipment running state at the same time. Has become a product quality control and assurance of an important means and methods. Based on the project of National Natural Science Foundation of China and the cooperation project of an alumina ceramic pipe manufacturing enterprise in Ningbo, this paper starts from the product quality problem in the production and molding process of alumina ceramic tube. The relationship between equipment failure and product quality of isostatic press is studied. Aiming at the quality problems related to product compactness, the hardware platform and software platform are built. The maximum pressure value and the holding time of the running parameters of the same static press are monitored in real time, and the quality of the products is monitored by the monitoring of the equipment parameters. The main work of this paper is as follows: In the first chapter, the background and significance of the system development are analyzed. Then, the research status and development trend of industrial equipment monitoring system at home and abroad are briefly introduced. Finally, the aim and main contents of the paper are discussed. In chapter 2, the process of isostatic pressing is introduced, and the factors influencing the product quality in the process of forming are analyzed. Then, the functional requirements of the state monitoring system of the static pressure machine are analyzed. On this basis, the overall design scheme of the system is put forward. Finally, the functional structure of the system is designed. In chapter 3, aiming at the field communication problem in system realization and application, the field communication technology of the system is studied. The communication protocol design of the system is completed, and the communication flow is introduced in detail. In chapter 4, based on the data of real time change of pressure value of isostatic press and statistical data of equipment failure, the causes of product quality problems are analyzed and the results are analyzed. The exponential smoothing method and the least square method are used to predict the trend of the maximum pressure value of the equipment, and to alarm the equipment failure according to the situation, thus providing support for the product quality assurance and the normal operation of the equipment. Chapter 5, complete the development and implementation of the system, including database design, system development and on-site installation and debugging. In chapter 6, the main results and conclusions of this paper are summarized, and the future work is discussed.
