Description

Technical Field

[0001] The present invention relates to the technical field of VR training systems, and in particular to a VR training system for a power plant production area. Background Art

[0002] With the rapid development of the power industry and the continuous innovation of technology, the production efficiency and safety of power plants have become the core concerns of corporate operations. However, traditional power plant training methods have many limitations, such as high training costs, difficulty in simulating real complex environments, and difficulty in evaluating training results. These have restricted the improvement of power plant employees' skills and the cultivation of emergency response capabilities.

[0003] For example, the patent with prior art announcement number CN118151760A relates to an integrated analysis method, platform and system for VR training, the method comprising: dividing the VR field of view into one or more sub-ranges; during the progress of the training content, obtaining the focus trajectory of the current user constituted by the sub-range where the user's focus is located; and obtaining a predicted focus set and its corresponding focus score based on the focus trajectory of the current user.

[0004] During the use of this system, it was found that the system mainly focuses on the field of VR training. It optimizes the rendering and presentation of VR training content by analyzing user focus trajectories, predicting focus sets, and other methods. Its application scope is relatively narrow, and its data integration capabilities are relatively weak. It mainly relies on user focus trajectory data. Summary of the invention
