Abstract
Description
Technical Field
[0001] The present invention relates to the field of virtual simulation teaching technology, and particularly to an intelligent virtual simulation teaching method and system for multi-person collaborative emergency handling of civil aviation cabin fires and evacuation of personnel. Background Art
[0002] Cabin fires occur in highly confined spaces, have short handling times, spread quickly, and are prone to losing control. Therefore, cabin crew members are required to be able to make quick responses, coordinate and coordinate with the team, calm passengers in a timely manner, and effectively maintain cabin order. Therefore, they have always been regarded as the focus of civil aviation safety and an important assessment point for civil aviation cabin crew members during the assessment and retraining stages. Although teaching ideas and strategies for handling cabin fires have been formed in work production and practical training, they are not targeted enough for complex situations such as multi-person collaboration, personnel evacuation, different fire scenarios, types, and degrees. Therefore, it is essential to construct a model for handling different cabin fire scenarios and evacuating personnel in the context of civil aviation digital transformation through virtual simulation. The operational requirements involved in the present invention are combined with the responsibilities of the cabin crew in emergency events in the "Large Aircraft Public Air Transport Carrier Operation Qualification Certification Rules" (CCAR-121-R7). Most of the evacuation models are in accordance with the "Airworthiness Standards for Transport Aircraft" (CCAR-25-R4). We have an in-depth understanding of the requirements of multiple airlines for cabin crew members, and have optimized the construction of virtual simulation fire handling and evacuation models, providing necessary references for cultivating qualified emergency safety handling crew members and for airlines to formulate cabin emergency plans.
[0003] It is precisely because of the diversity and complexity of cabin fire handling and personnel evacuation, as well as their typical interdisciplinary characteristics, that the training of relevant talents is particularly difficult. The existing teaching methods and resources can hardly meet students' needs for rapidly changing technology and management practices.
[0004] Therefore, it is necessary to provide a virtual simulation teaching system for cabin fire handling and personnel evacuation to meet the teaching and practice needs of students in related majors such as flight attendant and civil aviation transportation, and to cultivate practical talents in the digital economy era for the development of the civil aviation industry.

[0050] Specifically, information is exchanged between the main control teacher and students, and between students in the virtual simulation teaching module through the communication module.
[0051] Example 2
[0052] During the teaching process, each student plays a role designed for cabin crew fire handling in the system according to the assignment of the main teacher or freely chooses one. There are four types of roles: mainly firefighters, liaison officers, auxiliary firefighters and other crew members. Different role settings have different tasks and performances for cabin fire handling and personnel evacuation.
[0053] The cabin fire handling and personnel evacuation virtual simulation teaching system includes a main control module, which is respectively connected to a virtual simulation teaching module, a storage module, and a communication module. The virtual simulation teaching module includes: a cabin fire handling and personnel evacuation knowledge playback and explanation module, which accesses a cabin fire handling and personnel evacuation management knowledge database, calls relevant knowledge videos on cabin fire handling and personnel evacuation, and plays and explains them;
[0054] By selecting the fire scene, type and type of fire extinguishing equipment, the cabin fire handling and personnel evacuation knowledge playback and explanation module will pop up a list of corresponding knowledge points. After the students make their selection, the system will play a video to explain the corresponding fire characteristics and fire extinguishing equipment-related knowledge, the general concepts and composition of emergency fire handling based on different fire types, scenes and degrees, and the industry-specified knowledge and methods of fire handling and personnel evacuation.
[0055] The cabin fire handling and evacuation mode design simulation training module is used for the entire process of cabin fire handling and evacuation simulation construction and display of different scenarios, types and degrees of fire. Students select corresponding crew entity roles and scenarios for virtual design and display based on different scenarios, types and degrees of fire. Students independently construct new cabin fire handling and evacuation modes while meeting basic requirements, including creating new scenarios, entities and selecting fire-fighting equipment.
[0056] The cabin fire handling and personnel evacuation virtual simulation assessment and evaluation module evaluates the students' learning effects based on the built-in knowledge base and rule base of the storage module according to the corresponding algorithm, and automatically generates documents and performance reports in a standard format.

[0058] The core of the cabin fire handling and personnel evacuation virtual simulation teaching system is the knowledge presentation and interactive operation in the virtual scene, providing students with an immersive experience and an interactive method that is as natural as possible; the transfer of knowledge and the cultivation of abilities are presented in specially designed virtual scenes.
[0059] The construction and organization of virtual scenes are designed based on the whole process and functions of cabin fire handling and personnel evacuation. The scene is a virtual place for students to learn role-playing. Students' learning activities are carried out based on the scene. The same scene can be shared by multiple different roles and is also used in emergency response learning for different types and degrees of fire. The scenes mainly include the following categories:
[0060] 1) Typical fire scene discovery, scenes related to finding out the cause and clarifying the information, including but not limited to finding out the objects, confirming the cause, understanding the location, phenomenon, and people involved in the incident, etc., are designed according to the types and degrees of different fire scenes (including but not limited to luggage rack scenes, lithium battery scenes, and toilet scenes), which can fully reflect the characteristics and development trend of this type of fire. Students can learn to master the judgment analysis and decision-making methods of different fire types in this type of scene;
[0061] 2) Typical scenarios of multi-person collaborative firefighting, and scenarios related to the three-person firefighting team, mainly include three types of scenarios: firefighting disposal, reporting and contacting, and dedicated monitoring, involving the handling of different types of fires; including but not limited to reporting and contacting scenarios, implementation and disposal scenarios, and completion and disposal scenarios. Students can combine the knowledge they have learned about cabin fire handling and personnel evacuation to complete the operation and role learning of a three-person firefighting team suitable for fire scenarios; the specific roles (mainly firefighters, liaison officers, auxiliary firefighters and other crew members) are assigned as follows:
[0062] (1) The main firefighter. Usually the person who discovers the fire or the person closest to the fire-fighting equipment. His main responsibility is to find the source of the fire, use the fire-fighting equipment correctly according to the location of the fire, and put out the fire.
[0063] (2) Liaison officer. Mainly responsible for information transmission between the two crews (cabin crew and flight crew). The liaison officer should report relevant information to the captain in a timely manner according to the requirements of the company manual, and feedback further instructions from the flight crew to the cabin crew.
[0064] (3) Auxiliary firefighters. As the second firefighter, they are responsible for collecting the fire-fighting equipment and other available resources on board; monitoring the time and quantity of fire-fighting equipment; protecting themselves and replacing or helping the main firefighter in a timely manner; evacuating and relocating people in the fire source area, guiding and assisting relevant personnel to take protective measures; transferring or properly placing oxygen cylinders or other equipment in the relevant area; and, in the case of lithium battery fire emergency disposal, preparing containers suitable for cooling lithium batteries, equipment containing lithium batteries, or related luggage in advance.
[0065] (4) In addition to the cabin crew members who assume the responsibilities of the fire-fighting team mentioned above, other cabin crew members should assume their respective other cabin safety responsibilities according to their positions.
[0066] 3) Typical scenarios of passenger appeasement, which are related to cabin passenger safety management, mainly include two types of scenarios: appeasement of passengers and maintenance of cabin order; including but not limited to rearrangement of passenger seats, first aid treatment for injured passengers, appeasement of passengers and guidance of self-protection, and cabin order control. Students learn and master the skills and knowledge of passenger area location arrangement, passenger appeasement and guidance of passengers to implement self-protection, cabin procedure control, etc. in the scenarios, and eliminate safety hazards;
[0067] 4) Organize typical scenarios for evacuation, including but not limited to the number of designated evacuees, starting and target locations, the optimal route to the exit, walking speed, avoidance behavior, etc. Students can learn and master relevant knowledge and theories on evacuating and transferring passengers from related areas, and properly accommodating related passengers in these scenarios.
[0068] An assessment and evaluation module is set up in the cabin fire handling and personnel evacuation virtual simulation teaching system to evaluate students' learning activities in the system's built-in scenarios from two aspects: knowledge and operational skills. During the learning process, students use external devices to interact with the scenarios to complete learning and assessment.
[0069] The cabin fire handling and personnel evacuation virtual simulation assessment and evaluation module will evaluate the students' learning effects based on the students' input in the scene and the complete learning process, based on the built-in knowledge base and rule base of the storage module and the corresponding algorithm, and automatically generate documents and performance reports in a standard format to provide to students and the main teachers, forming an intuitive evaluation and diagnosis of the students' relevant learning effects.
[0070] Example 3
[0071] See also Figure 2 As shown, based on Example 1, this embodiment also provides a teaching method for a cabin fire handling and personnel evacuation virtual simulation teaching system, which is as follows:
