【摘要】 网络化制造是在全球范围内,充分利用优势互补的制造资源,灵活快速响应个性化的市场需求,提供优质服务的一种有效模式。随着网络化制造的发展,车间层生产控制在企业制造中的作用也在扩展,企业不仅需要通过内部网络进行生产控制,而且也追求通过Internet/Intranet进行企业间车间层协同生产控制,从而有效分享合作企业的制造信息、资源和技术,使自身不必投资大量的装备,就可以迅速提升装备能力和制造能力,增加企业的自适应能力,提高企业的柔性,快速响应外部环境,增强企业的市场竞争能力。要达到这一目标,就需在分布、异构的网络化制造环境下构建合理可行的车间层生产控制系统体系结构并研究其关键实现技术。本文在分析国内外网络化制造先进模式及其相关技术研究现状的基础上,结合计算机、网络、软件等技术及车间层生产控制模式的发展趋势,建立了一种车间层生产控制系统总体体系结构。该结构采用了以CORBA集成平台为核心的三层结构,构建管控一体化的分布式网络集成层来支持整个网络通信;在车间内部以CORBA平台和Agent技术构建信息集成模型,集成现存生产控制信息资源和应用服务等,并在这两层基础上构建了不仅为企业内部生产控制,尤其为企业间远程协同生产控制提供集成应用的应用服务层。其中设计了两个关键的车间层生产控制应用服务,一是构建了基于DNC集成技术和设备Agent技术的分布式DNC控制系统来实现车间现场设备的集成控制;二是设计了基于SOAP技术的远程服务代理来支持合作企业间远程协同生产控制。根据建立的总体体系结构,围绕车间层生产控制的一些关键支撑技术进行了较深入的研究,主要包括信息集成模型的Agent模式研究、通过DNC系统集成技术与设备Agent来实现企业内部的设备集成控制的研究等;在此基础上,进一步研究了SOAP 技术来支持企业间远程协同生产控制,重点对基于SOAP技术的远程服务代理在远程协同生产控制中的作用、实现机制、工作机理及协作方式等方面进行了较深入的研究;并且,重点研究了远程协同生产控制的实施方案及运行模式。 最后,以重庆市科委项目“江津增压器厂企业信息化应用示范工程”(项目编号:6901-01)作为工程背景,对论文提出的网络化制造中车间层生产控制系统体系结构及若干关键实现技术进行了应用验证。更多还原

【Abstract】 E-Manufacturing is a kind of manufacturing pattern which can organize the mutually supplementary manufacturing resources to meet customized market demands rapidly and provide high quality service. With the development of networked manufacturing, workshop floor production control plays a more and more important role in manufacturing. Virtual enterprises not only require control inside production via infranet/LAN,and specially require the distant cooperative production control among ally -companies via Internet/Infranet/LAN, which lead to effective share allies’ manufacturing information, resources and technologies, and can quickly enhance their abilities of enquipment and manufacturing without investing a great deal in NC devices. Then, enterprises can strengthen the ability of self-adaption and improve their own flexibility, agilely responsing to outside environment. In order to achieve the goal, researching on constructing reasonable and feasible workshop floor production control system architecture and key technologies in the distributed, different architecture and networked manufacturing environment is much required.Internal and external manufacturing patterns and its relative technologies are analyzed. Combining computer, commucation, network and the development trend of workshop floor production control pattern, an architecture of workshop floor production control is constructed,which has three layers centring CORBA platform , constructing network integrated layer charactered by management and control integrated and distributed to support the whole net communication, applying CORBA and Agent technologies to integrate these existing production control information, resources and application services inside workshops and on the basis of the two above layers, establishing application services floor to provide production control applications integrated to complete not only inside production control, and specially the remote cooperative production control among allies. In this layer, two key applications of workshop floor production control are designed,DNC system based on DNC integrated and device Agent technologies, and remote service Agent based on SOAP to support allies to implement remote cooperative production control.Based on the constructed architecture,some main key technologies to support the workshop floor production control are deeply researched, Agent pattern of information integrated model, DNC system integrated and device Agent technologies for inside device <WP=6>integrated control, and further research on the remote service Agent based on SOAP to support allies remote cooperative production control, especially focusing on its function,work mechanism and cooperative pattern. Moreover, the operation schema and the function pattern of remote cooperative production control among allies are researched.Finally, based on the application of Chong Qing Science Committee project, the demonstration enterprise information application project of Jiangjin Turbocharger Plant(6901-01), the system architecture and key technologies have been applied.更多还原
