【摘要】 网络化制造是当前的一种新的制造模式和理念,其本质在于充分利用当前日新月异的计算机和网络技术,结合制造业的特征和先进的集成管理理论,实现产品设计和制造的全数字化、智能化、网络化和集成化。在现有网络化制造系统中在数据通讯和信息识别存在问题,同时制造设备无法与潜在客户快速地进行信息互动。本学位论文在网络化制造等先进制造理念的基础上,对基于Web Service 的网络化制造环境下主动信息服务机制进行研究。在信息集成方面,依照信息主动服务的要求,采用EXPRESS 描述语言从制造设备的物理域、状态域和能力域等三个方面,建立了相应的EXPRESS-G 图,并依此为根据构造了制造设备数据模型,建立了相应的数据存储结构。同时研究了基于XML 实现制造资源信息共享机制所涉及的关键技术。本文运用下一代Internet 核心规范Web Service 及其相关技术如XML、SOAP、WSDL、UDDI 等,对基于Web Service 支持主动信息服务的网络化制造环境进行研究。该制造环境能够解决制造资源分散,协作性差的信息集成问题,更重要的是提供统一的用户信息传输接口,实现动态信息集成,可以作为针对主动信息服务的技术平台。在实现制造资源和产品信息共享的基础上,对主动信息服务框架进行研究,提出基于内容的信息过滤方法来实现个性化信息服务,并对主动信息服务的机制和实现技术进行了研究,提出基于Web Service 的网络化制造环境下主动信息服务机制。最后运用Web Service和XML等先进技术和规范部分实现网络化制造环境下主动信息服务的原型系统。更多还原

【Abstract】 Networked manufacturing is a distributed, weak coupling intelligent system. Besides the advanced manufacturing technology and theory, a series of correlative technologies are required to the implement of networked manufacturing, especially the technologies of distributed computing, information integration and artificial intelligent etc. Aiming at their limitations, the paper Research on Web Service based Active Information System in Network Manufacturing. The problem of how to communicated data and recognize information in networking manufacturing is crucial. The key to the problem is to realize the coherent description. The key technology of manufacturing resource sharing mechanism based on XML is studied in many aspects, such as the uniform resource framework based on EXPRESS, transforming EXPRESS model into XML DTD model. Furthermore, the information integration solution of networked manufacturing based on XML/STEP is researched. Based on the next generation Internet core protocol of Web Services and its relevant technologies such as XML, SOAP, WSDL and UDDI, a solution of Distributed Computing for networked manufacturing is researched. The solution, which featured with distributed, weak coupling and soft framework, enables enterprises and their partners to cooperate remotely more conveniently under the mode of multi-platform or/and multi-language. Finally, a web service based active service information system is implemented.更多还原
