Virtual simulation teaching system for helicopter falling-into-water escaping training

Abstract

The invention provides a virtual simulation teaching system for helicopter falling-into-water escaping training. The system comprises the components of a teacher subsystem which is used for editing helicopter falling-into-water escaping teaching material by a teacher, uploads the teaching material to a database server and searching the examination score of a student, and a student subsystem whichis used for studying and examination related with helicopter falling-into-water escaping by the student. According to the system, a real scene in helicopter falling-into-water is reproduced through three-dimensional simulation technology, thereby reproducing an escaping training full process of the personnel in compartment correction and overturning of the helicopter. The system operates in an offline and online combination manner. In offline operation, the student performs simulation training according to a teacher request, thereby getting familiar with the use method and the step of the whole simulation system; and in online operation, a processional teacher performs centralized teaching management, resource management, examination management, etc. The system settles a problem of incapability of realizing field practice by a large number of students and supplies an experience opportunity for underwater escaping from the helicopter compartment for the students.

Description

technical field [0001] The invention relates to the technical field of salvage and salvage engineering, in particular to a virtual simulation teaching system for helicopter overboard escape training. Background technique [0002] At present, maritime emergency support tasks have become more difficult, and helicopter maritime rescue, patrol, transportation, and military tasks are gradually increasing. At present, low-altitude flight is gradually opened up. As of August 2017, the number of civil helicopters in mainland China has reached 705, an increase of 21% over the previous year. However, the helicopter accident rate is relatively high, and it is easier to sink and overturn after an accident on the water surface, so that the occupants cannot escape quickly and drown. In order to ensure the safety of helicopter crew, theoretical research and training practice of helicopter underwater escape are urgently needed. However, in actual situations, helicopter underwater escape t...

AI Technical Summary

Problems solved by technology

[0003] 1. There are few domestic helicopters to simulate underwater escape equipment, so the training costs are expensive;

[0004] 2. The structure and function of domestic helicopter simulated underwater escape equipment are relatively simple, and it is difficult to train personnel in large quantities, resulting in low training efficiency for rescue helicopter personnel;

[0005] 3. The actual escape training lacks professional trainers, and the safety is not fully guaranteed;

[0006] 4. For other colleges and universities that do not have special underwater escape training equipment, helicopter underwater escape training is even more rare
