基于虚拟现实的灭火器使用训练系统设计与实现

Design and implementation of fire extinguisher training system based on virtual reality

由于安全风险和训练成本的限制,传统的教学方法难以为学生提供全面的消防安全知识和器械操作经验,使得学生无法高效、快速地掌握灭火器等消防器材的使用技能。而利用虚拟现实技术可以安全高效地让学生重复进行虚拟仿真训练,有助于解决上述问题。基于此,设计一种基于虚拟现实的灭火器使用训练系统。使用虚拟现实技术将知识讲解和实操演练相结合,搭建了虚拟实验室火灾场景;利用三维引擎设计了交互系统,并模拟了干粉灭火器的使用操作流程。此外,通过将具身认知理论和手势追踪技术进行融合,灭火器使用训练系统实现了无需外部设备的交互方式和创新引导方法。评价结果表明,所设计系统能够激发学生的学习兴趣,有效帮助学生掌握灭火器的操作技能和消防安全知识。

Due to the limitation of safety risk and training cost,it is difficult for traditional teaching methods to provide students with comprehensive fire safety knowledge and equipment operation experience,which makes students unable to master the use of fire equipment such as fire extinguishers efficiently and quickly.The use of virtual reality(VR)technology can safely and efficiently allow students to repeat the virtual simulation training,which can help to solve the above problems.On this basis,a fire extinguisher training system based on virtual reality is designed.The VR technology is used to combine instructional content with practical drills to build a virtual laboratory fire scene.The 3D engine is used to design an interactive system,and the operation flow of dry powder fire extinguisher is simulated.Furthermore,by integrating embodied cognition theory with gesture tracking technology,the fire extinguisher training system can introduce an interaction mode and innovative guidance method without the need for external devices.The evaluation results demonstrate that the designed system can enhance students’learning interest,and effectively help students master the operation skills and fire safety knowledge of fire extinguishers.
