【摘要】 计算机网络技术给制造业带来了重大的影响和革新,网络化制造已经成为制造业发展的主要趋势之一。企业信息化涉及到企业内部和外部,产品生命全过程,以及各个部门,因此需要集成多方面资源。为了保证数据的有效性、完整性、一致性,实现数据交换与共享,迫切要求对设计过程中的大量数据进行统一管理。设计开发出基于CORBA/XML的CAPP系统数据集成软件,保持了产品工艺数据的完整性和一致性,为企业生产提供快速、准确的数据源。本文在分析CAPP技术研究现状和发展趋势的基础上,结合CORBA/XML技术优势,讨论了CORBA/XML技术在数据集成中的实现方法。在详细分析系统需求状况的基础上,提出了在C/S和B/S混合工作模式下基于CORBA/XML技术的CAPP系统体系结构,划分了系统的功能模块。阐述了基于CORBA与XML技术的CAPP数据集成系统的设计思想和实现方法。讨论了运用XML文档树型结构模型描述产品制造信息资源的方法,同时讨论了CORBA技术在程序设计时的实现方法。提出了XML技术与传统的数据库技术相结合的方式,建立网络制造环境下CAPP系统数据库,实现运用CORBA技术对数据跨平台的集成,消息的发布、订阅等功能。分析了CAPP系统中CORBA功能需求,利用XML/CORBA和VC++程序设计语言等软件技术,实现了CAPP系统与CAD系统的数据通讯,以及实现从CORBA服务器的上传、下载功能。最后,结合已实现的软件系统的应用状况分析,验证CAD/CAPP数据集成的合理性和可行性。且具有较好的可扩展性,可以为今后与CAM/ERP/PDM等系统的数据集成提供接口支持。更多还原

【Abstract】 Network manufacturing has turned into a major trend in modern manufacturing industry with the revolutionary influence brought by computer network technology. Enterprise informationization, which involves internal and external factors, process of product life as well as all functional divisions, needs to integrate various resources. To ensure the validity, integrality and consistency of data, further promote data exchange and share, it is necessary to have a unitary control of data in the developing process. Based on CORBA/XML technique, the CAPP system is developed to maintain integrality and consistency of the manufacturing process, ensuring enterprises a speedy and accurate data source.Initially reviewing the situation and trend of CAPP system, this dissertation conducted a research on the possibility of applying XML technique on data integration with technical advantage of CORBA / XML. After a comprehensive analysis of CAPP system requirements, a framework of CAPP system on the basis of CORBA/XML under combined B/S and C/S model was put forward, also system functional modules were formed. The dissertation mainly explained the ideology and implementation of CAPP system based on CORBA/XML technology in the data integration.This dissertation discussed the methodology of depicting product manufacturing with an XML-based document tree and the applying of CORBA techniques in program developing. It also put forward a CAPP database system under network manufacturing environment in a mode of XML and conventional database techniques, hence realizing the trans-integration of data, information releasing and subscribing with CORBA technique.It analysed the functional requirements of COBRA under CAPP system and realized trans-system data exchange between CAPP and CAD as well as upload and download from a CORBA server with techniques of XML/CORBA, VC++ and other software.Finally, the rationality and feasibility of CAD/CAPP data integration are tested with an analysis of existing software systems. A good expansibility is confirmed to support connecting with CAM / ERP APDM systems.更多还原
