Design and implementation of workshop production data perception method based on digital twin
针对传统车间在进行数字孪生时,对于生产数据的采集存在着目标单一、信息模型灵活性差以及通用性低等问题,提出了一种面向数字孪生的车间生产数据感知方法.首先,通过分析数字孪生车间生产数据采集与应用需求,提出了一种多层次的生产数据采集体系架构;其次,围绕该体系架构的处理层,针对基于OPC统一架构(OPC Unified Archi-tecture,OPC UA)的生产资源数字化表征模型构建关键技术进行了重点阐述;最后,基于车间应用实例,结合关键技术以及体系架构开发了数字孪生系统,验证了该方法的可行性,有效支撑了装配车间数字孪生系统的运行.
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.
