基于语义 xBOM 的 MES 异构系统信息集成框架

摘要

The information exchange difficulties between MES and different application systems lead to the manu-facturing information island .To solve this problem , it proposes a heterogeneous information integration framework for MES based on semantic xBOM , presents the important part of the framework .BOM is the main form of infor-mation exchange between systems .Semantic xBOM is the core of this framework .It realizes the integration and sharing of information based on the semantic xBOM unified information model .Using the semantic and Web Service technology , it accesses the distributed BOM information with unified data interface , builds the semantic xBOM unified information hybrid ontology model based on information unified semantic description .And distribu-ted heterogeneous information source can be transparent accessed by using ontology semantic mapping informa -tion.The xBOM data manager can do the unified management and mapping of data and guarantee the integrity of information .Finally , it shows an example at digital factory workshop that a production monitoring and manage-ment system of MES verify the feasibility of the approach .%针对目前MES与企业大量异构应用系统信息交互困难，导致制造信息相互割裂形成信息孤岛的问题，提出了一种基于语义xBOM的MES异构系统信息集成框架，并对其中关键部分进行了分析。该集成框架以BOM数据作为系统间信息交互的形式，以语义xBOM为核心，在语义xBOM统一信息模型的基础上实现信息共享集成，通过语义和Web Service 技术实现BOM分布式信息的统一访问。利用混合本体语义技术和对BOM制造信息内容及信息间关系的分析，建立语义xBOM统一信息模型，实现信息的统一语义描述，利用本体语义映射实现异构数据源的分布式透明访问。通过构建语义xBOM数据管理器实现数据的统一管理和映射，保证信息的完整性和一致性。最后以某厂数字化车间MES-生产监控管理系统为例，对方法的可行性进行了实证。
