工业互联网环境下,我国生产型集团企业需要共享与协同制造资源和制造能力.针对这一需求,探讨了面向生产型集团企业的云制造服务平台的关键技术之一,即多源多领域知识融合与管理,构建了"领域本体-知识项-数据资源"三层结构的工程知识表达体系.通过云制造服务平台在某生产型集团企业应用实施,实现原型系统软件开发和技术验证.%In the environment of industrial internet, domestic production conglomerate need to share and collaborate on manufacturing resources and capabilities. In response to this demand, this paper discusses and studies one of key technologies concerned in cloud manufacturing service-oriented platform, namely integration and management of multi-source and multi-field knowledge. One expression architecture with three-layer engineering knowledge is proposed, namely "Field Ontology, Knowledge Item and Data Resource".The cloud manufacturing service-oriented platform is used in the manufacturing conglomerate to do original system software development and technical verification.
