The rapid development new generation of information technologies facilitate the emergence of cyber-physical production system (CPPS) which could pave a way to exploring new smart manufacturing solutions. Digital twin (DT) is the technical core for establishing CPPS in the context of industry 4.0. Developing an easy-to-deploy and simple-to-use DT-based CPPS is a critical research gap. In this paper, a systemic framework is proposed to provide guidelines for rapid system configuration and easy runtime of DT-based CPPS by integrating CPS, DT modeling technologies, event-driven distributed cooperation mechanisms, and web technologies. The concept of CPS node (CPSN) for manufacturing resources is established by integrating semantic information model, 3D geometric model and function modules. Various CPSNs are orchestrated as an autonomous CPPS using dynamic resource registration and binding technologies. To achieve easy runtime of DT-based CPPS, event-driven distributed cooperation among CPSNs and web-based remote control of CPPS are proposed respectively. Finally, to verify the feasibility of the proposed framework, a prototype of DT-based CPPS is implemented, based on which an exemplary case is conducted.

基于Web的数字物理生产系统的数字孪生建模和远程控制

快速发展的新一代信息技术促进了网络物理生产系统(CPPS)的出现,这可能为探索新的智能制造解决方案铺平了道路。数字孪生(DT)是在工业4.0环境下建立CPPS的技术核心。开发基于DT的易于部署和易于使用的CPPS是一个关键的研究缺口。本文提出了一个系统框架,通过集成CPS,DT建模技术,事件驱动的分布式协作机制和Web技术,为基于DT的CPPS的快速系统配置和轻松运行提供了指导。通过集成语义信息模型,3D几何模型和功能模块,建立了用于制造资源的CPS节点(CPSN)的概念。使用动态资源注册和绑定技术将各种CPSN编排为自主CPPS。为了实现基于DT的CPPS的简单运行,分别提出了CPSN之间事件驱动的分布式协作和基于Web的CPPS远程控制。最后,为了验证所提出框架的可行性,实现了基于DT的CPPS原型,并在此基础上进行了示例性案例。
