Abstract: Aiming at the problems of low transparency,single mode,poor real-time performance,and lack of models in the current manufacturing workshop monitoring,a six-dimensional model of a three-dimensional visual monitoring system for workshop based on digital twin was proposed and the system development process was introduced.The model referred to the digital twin theory model and used the industrial internet of things platform as the system service platform.On this basis,key technologies such as digital data acquisition,virtual workshop construction and real-time data mapping in system development were elaborated.At the same time,according to the current situation of workshop data collection difficulties,a digital data collection method based on the industrial internet of things platform was proposed.A three-dimensional visual monitoring system for the seal production workshop was designed and developed,which verified the effectiveness of the proposed model.The proposed method provided a reference for the realization of the three-dimensional visual monitoring in the workshop.

Key words: digital twins, 3D visual monitoring system, digital data, virtual workshop

摘要： 针对当前制造车间监控透明度低、方式单一、实时性差、缺乏模型等问题,参考数字孪生理论模型,以工业物联网平台作为系统服务平台,提出一种基于数字孪生的车间三维可视化监控系统六维模型,并介绍了系统开发流程。在此基础上对系统开发中的孪生数据采集、虚拟车间构建、数据实时映射等关键技术进行了阐述。同时,针对车间数据采集困难的现状,提出基于工业物联网平台的孪生数据采集方法。以印章生产车间为应用对象,设计开发了印章生产车间三维可视化监控系统,验证了所提模型的有效性,为车间三维可视化监控的实现提供了参考。
