【摘要】：发动机装配过程作为制造业生产过程中的重要环节,在实际运行中会产生大量的实时数据信息,伴随而来的是对信息进行分析处理和实现信息交互的需求。由于发动机装配过程存在设备种类繁多、装配信息多源、装配过程信息实时响应不足和缺乏可靠的信息系统等问题。本文从这一需求出发,针对发动机装配过程中存在的上述问题,以发动机装配过程数据挖掘为主要研究内容,通过对装配过程、CPS和数据挖掘方法的研究,构建了基于CPS的装配过程数据挖掘系统,主要内容包括以下几个部分:首先,分析了发动机装配过程的特点和装配过程的信息种类,系统阐释了CPS的相关概念和特征以及和物联网之间的关系,并对CPS的基本逻辑单元与结构进行了说明,给出了基于CPS的装配过程系统信息节点的设计方法和基于CPS的装配过程系统布局的设计思路。其次,研究了数据挖掘的相关方法,根据系统需求选择关联规则数据挖掘方法中的FP-Tree算法作为系统数据处理方法,同时采用Weka软件作为这一算法的实现途径并进行了展示说明。最后,以某发动机装配生产线为例,根据系统配置、扩展性和可视化的需求,使用FTPC平台和SQL数据库构建了基于CPS的装配过程数据挖掘系统,对系统的功能模块进行了介绍,实现理论研究的实际运用。
[Abstract]:As an important part of manufacturing process, the engine assembly process will produce a large amount of real-time data information in the actual operation, which is accompanied by the need to analyze and process the information and realize the information interaction. There are many problems in the engine assembly process, such as the variety of equipment, the multi-source assembly information, the insufficient real-time response of assembly process information and the lack of reliable information system. In view of the above problems in the engine assembly process, this paper takes data mining in the engine assembly process as the main research content, through the research of CPS and data mining methods in the assembly process. The assembly process data mining system based on CPS is constructed. The main contents are as follows: firstly, the characteristics of the engine assembly process and the information types of the assembly process are analyzed. The related concepts and characteristics of CPS and the relationship between CPS and the Internet of things are explained, and the basic logic unit and structure of CPS are explained. The design method of assembly process information node based on CPS and the design idea of assembly process system layout based on CPS are presented. Secondly, the related methods of data mining are studied. According to the system requirements, the FP-Tree algorithm of association rules data mining method is selected as the system data processing method. At the same time, the Weka software is used as the implementation way of the algorithm and illustrated. Finally, taking an engine assembly line as an example, according to the requirements of system configuration, expansibility and visualization, the assembly process data mining system based on CPS is constructed by using FTPC platform and SQL database. The function modules of the system are introduced. To realize the practical application of theoretical research.
