The factors causing coal mine disasters include gas, water, fire and dust, among which coal mine fires are more common in coal mine disasters, often caused by factors such as line aging and coal spontaneous combustion. Therefore, it is necessary to prepare more complete emergency rescue measures and prevention measures for coal mine fires;

[0003] For example, a Chinese patent with application publication number CN116881833A discloses an artificial intelligence-based fault operation and maintenance data transmission system and method, the system includes a data transmission management module, the data transmission layer of the data transmission management module uploads the processed data obtained by the data processing layer to the cloud corresponding to the application layer through a wireless network; the external device interacts with the cloud in real time through the external interface corresponding to the cloud, and when there is an abnormal risk source in the cloud data, a data transmission priority interaction channel is constructed, the associated device set to which the hydraulic equipment corresponding to the abnormal risk source belongs is extracted, and a set of interactive object data pairs of the data transmission priority interaction channel is generated. The present invention constructs a regional pump and gate mobilization association chain, which can quickly lock the relationship between abnormal risk sources, realize rapid screening of monitoring data, and realize rapid transmission of screened data through the constructed data transmission priority interaction channel, so that administrators can make feedback and decisions in a timely manner;

[0004] At the same time, for example, in a Chinese patent application with publication number CN116738360A, an air detection system and method based on a multidimensional fusion model is provided, including constructing a multidimensional air detection model that integrates multiple air detection devices for the target detection area; sorting out the corresponding feature information of all air safety events occurring in the target detection area; sorting out the distribution of feature information between air safety events caused by different detection areas, and judging and identifying historical air safety events with event correlation; calculating event correlation feature values ​​between each two detection areas, and feeding back to the management personnel terminal; when there are multiple air detection devices in the multidimensional air detection model at the same time showing abnormal detection data, the multiple air detection devices are divided, triggering the management terminal of the multidimensional air detection model to generate events to be checked.

[0005] The above patents all have the problems raised by this background technology: In the prior art, the three-dimensional scene construction system of mines has the following defects: traditional safety technology training uses text, pictures, and images as information carriers, and trainees passively accept them. There is a lack of interaction and practice, and the training effect is poor. The talent and technology inheritance of traditional equipment operation and maintenance is not systematic. Traditional forms of safety education are relatively boring, and learning lacks interactivity. The knowledge learned cannot be fully converted into skills, which reduces the quality of training. The production environment of mines is complex, and the operating technical level and safety awareness of employees play a vital role in the safe production of mines. It is necessary to simulate the scenes of mine production in advance, but the application of virtual technology in mine production scenes is not mature enough. In order to solve these problems, this application designs a three-dimensional scene construction system and method for VR in mines. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention proposes a system and method for constructing a three-dimensional mine scene for VR.

Based on VR technology, a rendering command is triggered after receiving the determination result, and the scene state of each node in the mine is determined according to the received simulation data ... The complete disaster evolution process of the three-dimensional model of each node in the mine is rendered and displayed on the screen. According to the disaster evolution process data and historical maintenance data of the three-dimensional model of each node in the mine, the best disaster emergency evolution picture is rendered and displayed on the display screen. Variables are input during the evolution process to randomly change the disaster development state of the three-dimensional model of the mine mining area. As the disaster development state of the three-dimensional model of the mine mining area changes, the best disaster emergency evolution picture is updated in real time. Only the environment and equipment conditions need to be changed to directly simulate and give results, which greatly shortens the design, verification and optimization time of fault measures.
