【摘要】：随着制造技术的高速发展,人们对产品质量的关注度也在不断提高。现阶段,许多制造企业都十分重视产品生产过程中的质量保障活动,但关注的焦点已不仅仅局限于产品质量的符合性或波动性是否满足要求,制造过程中的设备精度的保障早已与产品质量息息相关,对于设备精度的保障已经成为研究热点。在实时监控产品质量特征参数波动性的同时,对制造设备运行状态的实时监控,已经成为产品质量控制与保证的重要手段与方法。本文结合国家自然科学基金项目和宁波某氧化铝陶瓷管制造企业合作项目,从氧化铝陶瓷管生产成型工艺中的产品质量问题出发,研究等静压机设备故障与产品质量的相互关系。针对产品致密性相关的质量问题,在搭建硬件平台和软件平台的基础上,对等静压机运行参数中的最高压力值和保压时间进行实时监控,通过对设备参数的监控达到对产品质量进行监控的目的。本文所做的主要工作如下：第1章,首先分析了系统开发的背景与意义；然后,对国内外工业设备监控系统的研究现状和发展趋势进行简要介绍；最后,讨论了论文的目标与主要内容。第2章,首先介绍了等静压成型加工工艺,并对成型加工过程中的产品质量影响因素进行了分析；然后,对等静压机状态监控系统进行了功能需求分析；在此基础上,提出系统的总体设计方案；最后,进行了系统功能结构的设计。第3章,针对系统实现与应用中的现场通信问题,进行系统现场通信技术的研究。完成了系统的通信协议设计,并对通信流程进行了详细介绍。第4章,基于采集的等静压机压力值实时变化的数据及设备故障统计数据等,进行了产品质量问题原因分析。并根据分析结果,利用指数平滑法和最小二乘法对设备最高压力值的走向趋势进行了预测,据情对设备故障进行报警,从而为产品质量保障和设备正常运行提供支持。第5章,完成系统的开发与实现,包括数据库的设计、系统的开发及现场安装调试等。第6章,总结了本文研究的主要成果和结论,并讨论今后需要进一步开展的工作。
[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.
