【摘要】：地下采矿事故高发,建立三维矿井应急救援仿真系统可以有效提高受困人员逃生几率和救援人员救援效率以及提高矿井生产安全和培训质量。系统以三维立体的方式将地下巷道信息展现给用户,平时可用于监控安全生产。当矿难发生时,系统根据获取人员所处位置和巷道的通行状况信息设定安全点、起始点等参数,利用本文提出的改进蚁群算法自动规划出这两点间最佳避灾路线和备选路径,蚁群算法的重要改进在于通过引入分区概念影响蚂蚁的搜索行为,进而有效提高蚂蚁搜索路径的效率,通过实验表明本蚁群算法适合大中型煤矿的路径规划,求解最佳路径的效率和稳定性满足实际需求。另一方面,用户可以通过控制虚拟人在虚拟场景中的行为进行模拟安全训练,相比二维仿真系统,三维仿真系统可以更直观更有效地展现地下生产状况,用户感受深刻真实,改善以往录像、实验、幻灯等授课单调方式,有助于提高培训质量。最后本文在Unity3d的平台下实现了上述基本设计,并在实验中设计了水灾模拟算法,水灾发生后利用改进蚁群算法进行路径规划并将最佳路径在三维场景标色凸显,用户在此环境下控制虚拟人进行自主漫游和固定路径漫游。实验表明建立三维矿井应急救援仿真系统对于帮助部署应急救援方案、提高培训质量和矿井生产安全具有重要意义。
[Abstract]:There is a high incidence of underground mining accidents. The establishment of a three-dimensional mine emergency rescue simulation system can effectively improve the survival probability and rescue efficiency of trapped personnel, as well as improve mine production safety and training quality. The system presents the underground roadway information to the user in three-dimensional way, which can be used to monitor the safety of production. When the mine accident occurs, the system sets the safety point, the starting point and so on according to the information of the location of the acquired personnel and the traffic condition of the roadway, and uses the improved ant colony algorithm proposed in this paper to automatically plan the optimal disaster avoidance route and alternative path between the two points. The important improvement of ant colony algorithm is to improve the efficiency of ant search path by introducing the concept of partition to improve the efficiency of ant search path. The experimental results show that the ant colony algorithm is suitable for the path planning of large and medium-sized coal mines. The efficiency and stability of solving the optimal path meet the practical requirements. On the other hand, the user can conduct simulation safety training by controlling the behavior of virtual human in the virtual scene. Compared with the two-dimensional simulation system, the three-dimensional simulation system can show the underground production situation more intuitively and effectively. Improve the previous video, experiments, slides and other monotonous teaching methods, help improve the quality of training. Finally, this paper implements the above basic design on the platform of Unity3D, and designs the flood simulation algorithm in the experiment. After the flood, the improved ant colony algorithm is used to plan the path and highlight the best path in the 3D scene. In this environment, the user controls the virtual human for autonomous roaming and fixed path roaming. The experimental results show that the establishment of 3D mine emergency rescue simulation system is of great significance for the deployment of emergency rescue schemes and the improvement of training quality and mine production safety.
