In order to solve the problems of opaque distribution process,single monitoring means,poor real-time,and difficulty in intelligent control of digital workshop distribution,on the basis of analyzing the logistics monitoring needs of complex product assembly workshops,a real-time monitoring method of workshop logistics distribution driven by digital twins was present.The framework and operation mode of the digital twin system were constructed,and the key technologies such as the virtual modeling technology of the workshop and the real-time status information processing of the workshop logistics that supported the implementation of the system were studied.The service system was designed and developed.The experimental results show that the monitoring system improves the transparency,real-time and interactivity of workshop logistics significantly,so the proposed method is feasible.
