[0003] Invention patent 202311759955.0 provides a hydrogen station operation simulation training method based on physical model simulation. The hydrogen station operation simulation training device can conduct simulated operation, training and assessment for hydrogen station operators. It does not involve theoretical cognitive training, and does not use XR technology to conduct immersive simulation research on the training process; Invention patent 202310408650.9 provides an immersive simulation training system and its training method based on virtual reality technology. By wearing virtual reality interactive equipment, users are provided with immersive driving simulation training. However, this method only judges whether the user's operating posture meets the training requirements, and does not consider the impact of the operating steps on the overall performance and parameters of the system and the emergency response measures in emergency situations; Invention patent CN201910733097.X provides a rail transit vehicle maintenance simulation training method based on virtual simulation technology.
