Design and implementation of workshop production data perception method based on digital twin
Aiming at the problems of single target,poor flexibility of information model and low universality in the collection of production data in traditional workshops during digital twin,a workshop production data collection method for digital twin is pro-posed.Firstly,by analyzing the production data acquisition and application requirements of digital twin workshop,a multi-level production data acquisition architecture is proposed.Secondly,focusing on the processing layer of the architecture,the key tech-nologies of the construction of the digital representation model of production resources based on OPC Unified Architecture(OPC UA)are elaborated.Finally,based on the workshop application example,combined with the key technology and architecture,the digital twin system is developed,which verifies the feasibility of the acquisition method and effectively supports the operation of the digital twin system in the assembly workshop.
