【摘要】 基于CORBA的网络化制造软件平台研究和实现是针对传统制造业在现代信息化和网络化时代所面临的挑战和机遇而提出的解决方案。现代化的信息技术、计算机技术、Internet技术等促使制造技术朝着微小化、集成化、智能化、绿色化、网络化方向发展。本论文结合我国国情研究了将基于CORBA的网络化制造技术应用于制造业设备底层信息管理中的建模和实现问题，具体内容如下：首先，从国内外制造业的发展现状，研究了制造业面临的问题。提出了数控设备改造的可行性以及将分布式技术应用在制造业的可行性。研究比较了三种主要分布式技术：基于COM的OPC技术、基于RMI的JAVA技术和基于CORBA的分布式对象计算机技术。选定基于CORBA的分布式技术来管理设备底层信息。其次介绍了CORBA规范的发展历史和主要内容。CORBA技术作为当前主流的分布式技术，是基于OMG的OMA模型而建立的，本论文提出的网络化制造模型就以OMG的OMA模型而建立。随后研究了应用这个模型的几个关键技术研究。再次，研究了CORBA规范的命名服务结构和事件服务结构，详细地介绍了这两个服务的内容和结构。根据网络化制造模型，研究了命名服务和事件服务的实现问题。这两个服务将是网络化制造中最为关键的服务。在这些研究的基础上，本论文给出一个基于CORBA的网络化制造系统实例，采用命名服务和事件服务，以数控系统和伺服系统设备为模型，在机电学院的内部局域网内的实现。提出了命名服务中间件的概念并创建了应用实例。最后，针对设备数据采集的实时性，研究了实时CORBA技术，展望了将实时CORBA的实现ACE-TAO技术应用到网络化制造的前景，并将在数控网络化改造方面提供宝贵的经验。更多还原

【Abstract】 The research and Implement of CORBA-based network-manufacture is the solution scheme in allusion to the fact that the traditional manufacturing is facing with chances and challenges in the information and network times. Modern information technology、computing technology and Internet technology urge the manufacturing technology along the way to tiny、integration、intelligent、green、networking. This paper integrate the situation of our country and researches the questions of modeling and implement of using CORBA-based network-manufacturing in information management of devices at substrate of manufacture enterprise, the main content of the paper as follows:First, according to the status of manufacturing of international and our country, research the question that manufacturing is facing. We present the feasibility of the reconstruct of CNCs and the using of distributed technology to manufacturing. Then we research three main distributed technologies: COM based OPC、RMI based JAVA and CORBA based DOC. Finally we think the CORBA based DOC is the best solution.Then this paper introduces the history and content of the CORBA specification. The CORBA as the leading distributed technology is based on the OMA model of OMG. The model that this paper gives accords to the OMA. Then researches some key technologies in using this model.Then this paper researches the structure of Naming service and Event service of CORBA specification and introduces the two service’s content and structure in detail. According to the model, researches the implementation of the two services. This two services is the key services of network-manufacture.Based on the researches, this paper gives an example of<WP=5>network-manufacture. This example uses Naming service and Event service, the CNCs and Servos as the models, is implemented in Intranet of machtronic apartment. Also this paper gives Naming middleware concept and an instance of the software.Finally according to the Real-Time requirement of data acquirement of devices, this paper researches the Real-Time CORBA and gives the prospect of using ACE-TAO in network-manufacturing. This paper gives valuable experiences in reconstructing the CNC adapt to network-manufacture.更多还原
