[0046] A training method for handling emergencies on board aircraft based on virtual reality technology, the method is implemented based on a training system for handling emergencies on board aircraft, the system comprising a server, a VR headset and a VR handle, the VR headset and the VR handle being connected to the server. The server is preset with a three-dimensional model of the cabin interior. The method comprises the following steps: the trainee, with the help of the VR glasses and the VR handle, completes a series of training items set according to the type of emergency on board aircraft and role information in a preset scene in sequence under the guidance of the server.

[0047] When faced with an onboard explosive emergency disposal task, the process of the method specifically includes:

[0048] 1) Mission Background

[0049] The system provides a mission background description, which mainly includes flight information, onboard crew status, emergency event introduction, and tasks to be performed, and displays a cabin plan with the locations of dispatchable personnel marked on it.

[0050] 2) VR scene loading

[0051] 3) Trainees will serve as security team leaders to perform emergency response tasks for explosives on board

[0052] 3-1) Issue instructions

[0053] The system guides trainees to the front galley to issue instructions, specifically by guiding them to complete the intercom broadcast to issue instructions, including notifying passengers of emergencies.

[0054] 3-2) Task Assignment 1

[0055] The task to be executed is prompted, and the task assignment interface is displayed in a floating window. The interface includes the dispatchable personnel and their role information arranged vertically on the left, and a list of optional tasks on the right, with a prompt "Please select with the ray, hold down the disc key and drag the task instruction to the person on the left."

[0056] In this embodiment, the personnel available for dispatch include 1 safety officer, 1 crew chief and 3 crew members, and the 3 crew members are marked as crew members No. 2, 3 and 4 respectively.

[0057] The tasks in the task list include forming a team (forming a combat team), alert (guarding the cabin), monitoring (monitoring the front cabin), clearing (clearing the rear four rows, paying attention to balancing), transferring (transferring oxygen cylinders / fire extinguisher bottles), taking orders (taking emergency response orders), asking for instructions (reporting to and asking for instructions from the crew), closing (turning off the power of the rear cabin), releasing (releasing the arming of the right second door), building (building the base of the Class B item platform), cooperating (alert and cooperating), reading orders (reading emergency response orders), locking (checking and locking the luggage racks), intercom (intercom broadcasting), calming (calming down passengers' emotions), etc.

[0058] In this operation, tasks are assigned to the security officers through the task assignment interface: team formation.

[0059] 3-3) The system automatically marks the row where the explosives-related personnel are located and the three rows in front and behind, relocates the passengers in the area, and instructs other passengers to lie on the backrests of the seats in front of them. At the same time, the luggage racks in the marked area are opened, and the explosives are randomly pre-placed in the luggage racks in the marked area by the system. The randomness here includes the double randomness of position and quantity, and the shape of the explosives is also random. The randomness of the position and quantity of the explosives is conducive to cultivating the trainees' awareness of complete screening, and the randomness of the shape is conducive to strengthening the trainees' sensitivity to explosives of different shapes.

[0060] 3-4) Guide the trainees to the marked area such as 42-48 rows and instruct them to be on guard. At this time, carry out task assignment 2:

[0061] Assign tasks to security guards: alert;

[0062] Assign the chief steward the task: monitoring.

[0063] 3-5) Guide trainees to check for explosives on luggage racks in rows 42-48.

[0064] 3-6) After completing the explosives inspection, the task content will be prompted, and task assignment 3 will be performed through the task assignment interface:

[0065] Assign tasks to crew member No. 2: clear and transfer;

[0066] Assign tasks to crew member No. 3: take orders, ask for instructions, and close;

[0067] Assign tasks to crew member No. 4: dismantle and assemble.

[0068] 3-7) Guide trainees to build the platform base through the platform construction floating window

[0069] The platform construction window appears. The left side of the window shows the hatch area on the left side of the rear of the cabin where the platform will be built, and the right side shows the available items, including:

[0070] Luggage, lunch boxes, medical kits, seat cushions, plastic bags, blankets, fire extinguishers, purified water, tape, ropes, life jackets, headrests, kettles, etc.;

[0071] At the same time, the left hatch area displays the base elevation line and prompts to drag objects to build the platform base.

[0072] The trainee can drag the suitcase to complete the bottom construction of the platform base, and then drag the seat cushion until it reaches the base elevation line to complete the platform base construction. If the dragged object is wrong, an unusable reminder will appear.

[0073] This embodiment sets a plurality of interference items on the available items, so that the trainees can have a clearer judgment on the truly available items.

[0074] Building the platform base is an important process. Even if the system assigns other NPCs (characters) to perform this task, trainees are still required to undergo command training in order to enhance their familiarity and mastery of this link.

[0075] 3-8) Guide the trainee to perform task assignment 4 through the task assignment interface:

[0076] Through the task allocation interface, assign the safety officer to cooperate and the No. 3 crew member to read the order. The trainees can also make other arrangements for the specific allocation method.

[0077] 3-9) The system guides the trainee to insert the emergency disposal form under the explosive to confirm that the explosive can be moved.

[0078] 3-10) Transfer of explosives

[0079] The screen shows a handling posture adjustment control frame K, prompting the trainee to prepare for the posture. At the same time, a tilt monitoring indicator plate also appears. The structure of the tilt monitoring indicator plate is as follows: Figure 1As shown, it includes a pointer a and a semicircular chassis b. The pointer a is set at the center of the chassis b. The middle of the chassis b is marked as a green safety zone b1, and its two sides are marked as a yellow danger zone b2 and a red failure warning zone b3 in sequence as the offset angle increases. The pointer a rotates to the corresponding zone according to the stability of the explosive D during transportation, and when the pointer a rotates to the failure warning zone b3, it indicates that the transfer of the explosive D has failed. C is a timer.

[0080] 3-11) Complete platform construction

[0081] A platform construction pop-up window appears, showing that the explosives have been placed on the constructed platform base, prompting the trainee to drag the pile of items to the top elevation line marked on the platform position, and then the system automatically completes the fixing of the platform.

[0082] 3-12) Guide trainees to complete intercom calls in the rear kitchen, including intercom calls to the chief steward and the crew to report situations, etc.

[0083] Step 3-1) The internal conversation is completed in the front kitchen, because in actual work, the security team leader needs to negotiate with the crew chief first. In this step, the internal conversation is completed in the back kitchen, because the security team leader needs to stay in the back kitchen to monitor the entire fixing process of the explosive (clamping and fixing it in the built platform).

[0084] 3-13) The system prompts the tasks to be completed, and the tasks are assigned through the task assignment interface 5:

[0085] Assign the task to crew member No. 3: lock;

[0086] Assign the task to crew member No. 4: lock.

[0087] 3-14) Arrange seats for each character in the cabin

[0088] A cabin plan is displayed, in which a monitoring area G is marked according to the type of emergency, such as the location of the explosive in this application, and the cabin seating instructions for each character are marked in different colors. The instructions are made in consideration of monitoring the monitoring area G, such as Figure 2 The cabin plan also displays a list of roles, and assigns different color icons F to different roles. Guide the trainees to drag each role to the position of the corresponding color icon F in the cabin to complete the role cabin seating arrangement. E is a timer.

[0089] Afterwards, the trainees went to the corresponding positions according to their own position arrangements and sat down to complete the training.

[0090] This invention is the first VR training model in the same field in the domestic aviation industry. It can rationalize the process steps in reality and reproduce them in VR, providing trainees with a more realistic training experience. Through the VR training of this system, trainees can enhance their understanding of the business requirements and the meaning behind the details, effectively promoting training results.
