Description

Technical Field

[0001] The invention relates to the technical field of aircraft escape simulation, and in particular to a virtual simulation system for underwater escape simulation training. Background Art

[0002] Helicopter underwater escape simulation training is a virtual simulation training for underwater escape scenarios in helicopter accidents; this training simulates the scene of a real helicopter falling into the water, allowing participants to perform escape operations in a virtual environment to improve their coping and survival skills in real accidents. Helicopter underwater escape simulation training can improve safety awareness, enhance escape skills, reduce accident risks, and improve coping capabilities. In summary, the significance of helicopter underwater escape simulation training is to improve participants' safety awareness, escape skills and coping capabilities, reduce accident risks, and provide effective training and preparation for underwater escape in helicopter accidents.

[0003] Prior art 1. Application number: CN 201811537181.6 discloses a virtual simulation teaching system for helicopter water escape training, a teacher subsystem for teachers to edit teaching materials for helicopter water escape, upload the teaching materials to the database server, and query the assessment results of students, and a student subsystem for students to learn and assess about helicopter water escape. Through three-dimensional simulation technology, the real scene of the helicopter falling into the water is reproduced, and the whole process of personnel escape training when the helicopter is in the upright position and flipped is restored. Although it is carried out in a combination of offline and online methods, offline students mainly conduct simulation exercises according to the requirements of teachers, and are familiar with the use methods and steps of the entire simulation system, while online professional teachers mainly conduct centralized teaching management, resource management, assessment management, etc., which solves the problem that a large number of students cannot practice on site, and provides students with the opportunity to experience underwater escape from the helicopter cabin. However, its simulation effect is poor, there is a gap with the real scene, and the replacement of the simulation scene cannot be realized.

[0004] Prior art 2, application number: CN 201910340192.3 discloses a simulated helicopter crew escape and life-saving training system and training method, which includes a simulated marine life-saving training pool, which is a swimming pool that can simulate waves, and a helicopter crew escape training device, which contains a training caisson and a crane, the crane is fixed to the ground on the side of the training pool, the training caisson simulates a helicopter, and the training caisson is hung in the training pool by a crane, and the training caisson can roll in any direction in the training pool. Although the training environment is close to actual combat, the simulation of waves and wind and rain in the training pool can be controlled, and the trainees can gradually increase the difficulty of training according to the training outline, and the training pool and the helicopter crew escape training device have scientific and reasonable structures. However, its production is complicated, the investment cost is large, and once built, it is difficult to change.

[0005] Prior art three, application number: CN 201910060538.4 discloses a helicopter water escape training device, including: a guide rail frame, a top plate, a bottom plate and a plurality of side plates with openings, the guide rail frame includes a main frame of a closed figure and an upper frame and a lower frame parallel to the horizontal plane fixed to the inside of the main frame, the top plate and the bottom plate are fixed to the upper frame and the lower frame respectively, the side plates include front and rear side plates and left and right side plates, the front and rear side plates are fixed to the two ends of the upper frame respectively, the left and right side plates are fixed to the inner side wall of the main frame respectively, the top plate, the bottom plate and each side plate form a closed space under the fixation of the guide rail frame, and also include a simulator brake mechanism connected to the guide rail frame for hoisting the guide rail frame. Although the structure is stable and the space in the cabin is wide through the connection between the guide rail frame and the side plate, it is suitable for multiple people to train at the same time, and the scene after the helicopter falls into the water is truly simulated. However, its structure is relatively simple, and the degree of intelligence is explained, which cannot be applied to the scene and precision requirements of helicopter escape.

[0006] At present, the existing technologies 1, 2 and 3 have a relatively simple simulation system structure and a low degree of intelligence, which cannot effectively improve the simulation effect. Therefore, the present invention provides a virtual simulation system for underwater escape simulation training, which effectively simulates the situation of helicopter underwater escape, allowing passengers to conduct practical training in a safe environment, which can improve the passengers' coping ability and reaction speed, enhance their self-rescue ability in emergency situations, and reduce the risk of casualties when accidents occur.
