An Approach of Digital Twin System Construction for Underground Locomotive Dispatching Management

For addressing the problems that the existing data cannot be effectively integrated with the process control decision-making in the digital mine system, a digital twin system for underground locomotive dispatching management is proposed in this work. Firstly, the designed digital twin system has a four-tier system architecture, while the part of theoretical prior model is established by Petri nets, and the actual dispatching is constructed by integrating simulation software and a three-dimensional (3D) virtual mapping for underground mines. Then, the effectiveness of dispatching algorithm and the consistency of twin information are systematically evaluated through the setting of simulation parameters and the access of twin data. The designed digital twin system of underground locomotive dispatching can not only visualize the dispatching system in two directions, but also provide decision-making basis for the safety of locomotive dispatching, which deepen and widen the application scope of digital twin system in the field of intelligent mine construction.
