【摘要】 随着科技创新尤其是信息技术的迅速发展,以及市场竞争的日益激烈,制造类企业在宏观政策的引导下,制造业纷纷筹建以信息技术为依托的数字化车间,以实现提高生产效率,降低生产成本、提高产品质量的目标。本文以工业和信息化部财政部2016年智能制造综合标准化与新模式应用项目“高端液压元件制造数字化车间”项目为依托,为实现高端液压元件制造转型升级需求,开展农机装备高端液压元件智能制造中数字化车间建设,开发设计制造执行系统,改善目前生产企业存在的信息断层和信息孤岛问题,通过数据采集获取底层过程控制系统中各类生产相关信息,对车间生产状况进行跟踪,实现产品质量追溯。论文主要研究内容包括:通过对液压元件产品结构以及制造流程的分析,设计数字化车间物理模型和课题侧重研究的装配车间模型。阐明数字化车间建设中制造执行系统的连接信息上下层,传递与沟通的重要作用,以及制造执行系统功能之生产跟踪功能在制造执行系统中重要性,并根据高端液压元件生产特点,分析针对高端液压元件制造的生产跟踪主要内容:工单跟踪、物料跟踪、质量追溯等。实现生产跟踪需要获取大量生产数据,因此数据采集是是生产跟踪的基础,是企业建设数字化车间,实现企业信息化管理准确并时实有效的重要保障。论文通过对数据采集基本原理的分析,搭建针对高端液压元件制造的数据采集点模型,并针对采集点的类型不同采取相对应的采集方式。其中RFID射频识别技术为数字化车间数据采集提供了可靠的技术支持。根据前期对数字化车间数据采集和生产跟踪的研究与建模,针对某一高端液压元件制造企业的实际生产状况进行需求分析,设计系统所必须的数据库为后期系统开发做好准备。论文在前期理论研究、设计模型以及需求分析、功能模块设计的基础上完成数据采集与生产跟踪子系统的开发。更多还原

【Abstract】 With the rapid development of technological innovation,especially information technology,and the increasingly fierce competition in the market,under the guidance of macroeconomic policies,manufacturing companies are preparing to build digital workshops based on information technology in order to increase production efficiency and reduce production cost and improve product quality target.In this paper,the Ministry of information industry and the Ministry of Finance in 2016 intelligent manufacturing comprehensive standardization and application of a new model of project "high-end hydraulic components manufacturing digital workshop" project,to achieve the high-end hydraulic components manufacturing transformation and upgrading needs to carry out agricultural equipment,high-end hydraulic components intelligent digital workshop construction manufacturing,manufacturing execution system design,solve information island and the fault information problems of production enterprises,collect all kinds of acquisition process control system in production related information through the data,tracking the production condition,the product quality traceability.The main contents of the paper are as follows: by analyzing the product structure and manufacturing process of hydraulic components,we design the assembly shop model of the digital workshop physical model of hydraulic components manufacturing and the research focused on the topic.To clarify the connection information on the lower in the construction of digital workshop manufacturing execution system,the important role of transfer and communication,as well as the functions of the manufacturing execution system of production tracking function in manufacturing execution system importance,and according to the production characteristics of high-end hydraulic components,hydraulic components analysis for high end production of the main contents of the single track tracking and material tracking quality traceability.To achieve production tracking,we need to get a lot of production data.Therefore,data acquisition is the foundation of production tracking,and is also an important guarantee for enterprise to build digitalized workshop and achieve enterprise information management accurately,timely and effectively.Based on the analysis of the basic principles of data acquisition,a data acquisition point model for high-end hydraulic components manufacturing is built,and the corresponding acquisition mode is adopted for different types of acquisition points.RFID radio frequency identification technology provides reliable technical support for data acquisition in digital workshop.According to the research and modeling of data acquisition and production tracking in the early stage,we need to analyze the actual production status of a high-end hydraulic components manufacturing enterprise,and design the database of the system to prepare for the later system development.In this paper,the development of data acquisition and production tracking subsystem is completed on the basis of previous theoretical research,design model,demand analysis and functional module design.更多还原
