【摘要】 从产品生命周期的视角,提出基于分布式广义知识库系统支持的产品协同设计系统的体系结构,该结构包括三个层次:基础层、应用层和决策层。研究基于知识的工程系统支持CAD协同、产品信息建模及可视化仿真的方法,系统论述各层次的设计数据管理和交换机制。在基于知识的工程环境下,研制面向产品生命周期的协同设计系统框架。给出断路器开发实例,实现其生命周期协同开发的数据和知识的交流与共享。更多还原

【Abstract】 From the view of PLC (product life cycle), we propose an architecture of collaborative design system that is supported by distributed general knowledge base. It includes three layers: base layer, application layer, and decision-making layer. The methods are studied, which are knowledge-based engineering system to support collaborative CAD, product information modeling, visualization simulation. Data management and exchange mechanism for every layer are discussed in detail. We develop framework of collaborative design system for PLC under the KBE (Knowledge-Based Engineering) environment. Finally, we give sample of breaker development to implement data exchange and share for PLC collaborative design.更多还原
