Modeling Method of Dynamic Knowledge Graph for Distributed Manufacturing Resources in Cloud Manufacturing

As a service-oriented manufacturing mode, cloud manufacturing has made great progress and technological innovation in recent years by encapsulating manufacturing resources into services. However, the construction of manufacturing resource model basically stays in a static model which lacks authenticity for resources with dynamic properties. This paper establishes the real-time data acquisition and transmission framework of manufacturing resources, and puts forward a dynamic modeling method based on knowledge graph. By building a prototype system of cloud manufacturing platform, the feasibility and effectiveness of data transmission and model construction are verified.
