基于CORBA-MAS的装配系统信息集成框架研究

Information Integration Framework Research of Assembly System Based on CORBA-MAS

针对产品装配过程中多源异构信息的集成问题,在分析产品装配过程信息组织形式的基础上,基于角色和功能对装配过程进行了分解,定义了制造单元映射、制造单元联盟和制造单元合并的信息集成分类模型,引入了公共对象请求代理体系结构(Common Object Request Broker Architecture,CORBA)和Agent技术,建立了MAS(Multi Agent System)系统,并在此基础上提出了基于CORBAMAS的集成框架。通过建立MAS的协作模型,采用可扩展标记语言(XML)对信息进行表达和封装,有利于Agent之间的协作。基于上述理论开发了基于CORBA-MAS的资源信息集成原型系统,并成功应用于北京某汽车发动机装配车间,验证了该信息集成框架的可行性和有效性。

In order to integrate multi-source heterogeneous information effectively in the product assembly process,this paper analyzes the role and function of the assembly process based on the analysis of product assembly process information organization form. Then define the information integration classification model of manufacturing unit mapping,manufacturing unit alliances and manufacturing unit merging. This paper introduces Common Object Request Broker Architecture,CORBA and Agent technology,establishes M AS system,on the basis of which,proposing integrated framework based on CORBA-M AS. Through establishing of the M AS collaboration model,the paper uses Extensible M arkup Language（ XM L） to express and package information,which is benefit to the collaboration between Agents. On the basis of the Theory above,the Paper develops a Resource information integration prototype system based on CORBA-M AS,applied to a Beijing automobile engine assembly plant successfully and verifies the feasibility and effectiveness of the information integration framework.
