Abstract: In order to enhance the lithium battery fire emergency response capabilities of cabin crew, solve the limitations of traditional fire drills such as single and fixed scenarios, difficulty in achieving multi-person cooperation, and subjectivity of evaluating ability, the "teaching-learning-test-evaluation" civil aviation cabin lithium battery fire VR emergency drill platform was developed based on Virtual Reality technology, which could achieve nonscript, overall process, evaluation and multi-person cooperation functions. Firstly, the CBTA-CRM model was proposed and designed to meet platform's drill requirements, functional framework, and evaluation dimensions. Secondly, the Untiy3D game engine and 3Dmax were used to realize the system development of platform scenes, characters and tasks. Thirdly, the modular development of software system was realized and linked with hardware system, which were completed and integrated with network data transmission system. Finally, taking the fire accident of lithium battery in the luggage rack and seats of passenger cabin as examples, the aviation crew were invited to cooperate in groups to conduct the whole process exercise. The results show that the VR drill platform can achieve the lithium battery fire emergency tasks, support the multi-person cooperative and nonscript emergency drills, and conduct overall process evaluation, which improves crews team cooperation and enhances the lithium battery fire emergency response capabilities.
