Abstract: In order to improve the management efficiency and real-time data of the production site， a copper mine has carried out the research and deployment of the three-dimensional visual scheduling sys⁃ tem and the industrial Internet of Things data acquisition platform in view of the problem that the original scheduling system control large screen has been running for many years and can not meet the current pro⁃ duction management needs and the data of each plant area are independent of each other and difficult to converge and connect in real time.A digital twin that is“synchronized”with the physical world is construct⁃ ed，covering key links such as concentrators，roasting plants，smelters，220 kV substations，and test de⁃ tection. Through various industrial protocols such as OPC DA，OPC UA，and IEC61850，real-time data collection，aggregation，and connectivity of each production plant are realized，and real-time and histori⁃ cal data support is provided for the upper three-dimensional visualization system through the RESTFUL API.
