Digital twin-based virtual-real interaction technology for processing lines
Aiming at the problems of difficult equipment data acquisition and low visualization in the operation process of traditional processing production line,the application of digital twin(DT)technology in the virtual-real interaction of processing production line was proposed.Firstly,a motor casing processing production line was taken as an example,and the processing flow of the production line was analyzed,the overall framework of the virtual-real interaction technology was designed,and specific methods were proposed.Then,the digital twin modeling of the processing production line was carried out,and the key elements in the model,the geometric,physical,behavioral attributes and the construction of communication interfaces were elaborated in detail.Finally,the object linking and embedding for process control(OPC)technology was used to collect and process heterogeneous data from multiple sources in the processing production line,and the mapping between real-time data was accomplished.The research results show that the real-time mapping between the physical production line and the digital twin can be accomplished by using the real-virtual interaction technology;the reliability of the real-virtual interaction of the robotic arm is as good as the reliability of the physical production line and the digital twin.The reliability of the real-virtual interaction of the robotic arm is99.95%,which meets the accuracy requirements;the service module can reflect the actual processing status of the production line more intuitively and effectively to meet the dynamic visualization of the processing process information,which proves the feasibility and validity of the scheme.
