【摘要】：针对多品种、小批量的生产方式以及人工成本上升等诸多因素,越来越多的制造企业采用柔性自动化生产线。柔性生产制造过程中会产生与利用大量的信息,其中涵盖了包括毛坯、机床、工艺装备在内的工艺静态信息以及大量的工艺数据信息等工艺动态信息。由于不同的柔性制造系统的组织结构、运行机理不同,工艺信息的组织方式也不同,因此针对某个具体柔性制造系统而言,如何才能够有效地将工艺信息进行组织管理起来形成信息流,提供给制造系统所使用,是值得研究的问题。本文以某数控技术有限公司的“某柔性自动化生产线”为对象,就其工艺的信息组织技术进行了如下方面的研究:1)介绍了两种信息组织的基础理论即系统论与协同论,探讨了几种相关实现技术即系统间集成技术、消息通知技术以及数据可视化技术。2)具体分析了本文所研究的柔性自动化生产线的组织及运行机理。3)给出了一种面向柔性制造过程的工艺信息模型,其中包括零件信息模型、工序信息模型、数控机床设备模型、柔性生产线模型以及其它生产资源模型。4)将所建立的工艺信息模型运用到柔性自动化生产线上,并且提出了多工艺路线技术、数控资源动态迁移技术。5)提出了工艺可行性的概念,并且分析了工艺可行性检验的必要性,对工艺过程进行Petri网建模,实现工艺可行性的监测。6)结合信息化技术与工业自动化技术,采用OPC控制技术与WCF即时通讯技术设计开发了柔性制造工艺管理系统,实现上层计划信息至中间执行层再到底层设备层的信息流转,保证了企业计划层和底层控制系统的无缝对接。
[Abstract]:More and more manufacturing enterprises adopt flexible automatic production line in view of many factors, such as multi-variety, small batch production and the increase of labor cost. A large amount of information will be generated and utilized in the flexible manufacturing process, which covers the process static information, including blank, machine tool, process equipment, and a large amount of process data information and other process dynamic information. Because different flexible manufacturing systems have different organization structure, different operation mechanism and different organization mode of process information, so for a specific flexible manufacturing system, It is worth studying how to organize and manage the process information effectively to form the information flow and provide it to the manufacturing system. In this paper, a flexible automatic production line of a numerical control technology co., Ltd is taken as the object. The information organization technology of the process is studied in the following aspects: 1) two basic theories of information organization, namely system theory and cooperation theory, are introduced. This paper discusses several related implementation technologies, that is, the technology of system integration. Message notification technology and data visualization technology. 2) the organization and operation mechanism of flexible automatic production line studied in this paper are analyzed. 3) A process information model for flexible manufacturing process is presented, which includes part information model. Process information model, numerical control machine equipment model, flexible production line model and other production resources model. The concept of process feasibility is put forward, the necessity of process feasibility test is analyzed, and the process process is modeled by Petri net. Based on the combination of information technology and industrial automation technology, the flexible manufacturing process management system is designed and developed by using OPC control technology and WCF instant communication technology. The information flow from the upper planning information to the middle execution layer and then to the underlying equipment layer is realized, which ensures the seamless connection between the enterprise planning layer and the bottom control system.
