The system constructs digital twin simulation models for train dispatching, environmental control dispatching, power dispatching, information dispatching, maintenance dispatching, CCTV, etc., based on the actual operation scenarios and training needs of urban rail transit. It is a dispatching and command training system that integrates simulation models of signaling, communication, power supply, environmental control, etc., and is established in combination with actual operation lines. To address the pain points in current urban rail transit operation, such as the independent training of single-trade dispatching professionals and the lack of multi-trade collaborative training, the system adopts distributed collaborative simulation and virtual reality simulation technologies to achieve simulations of train fleets, train-network coupling, joint control of power and environmental control systems, joint control of train operation and environmental control systems, as well as the interlocking logic control among train dispatching, power dispatching, and environmental control dispatching. It can realize functions such as subway operation plan simulation drills, training for standard operations and abnormal fault operation scenarios, emergency plan drills and comparison, and accident cause analysis. Moreover, it can conduct assessment and evaluation of the entire teaching and training process and evaluate the training effectiveness.
