Abstract

The invention discloses a modular construction method and system for a simulation scene of helicopter earthquake rescue, which relates to the general aviation/helicopter operation support field. According to the method, on the basis of characteristics, like intensity attenuation and house vulnerability, of the earthquake, the construction system is divided into seven modules, so that the modeling staff can construct an earthquake rescue simulation scene scientifically and reasonably without any professional earthquake knowledge. During the application process, construction is carried out based on the divided seven modules; all the modules are integrated according to steps and rules to obtain an earthquake simulation scene with a high reduction degree quickly. Moreover, because the system and method are especially used for the simulation scene of helicopter earthquake rescue training and the models are layered and simplified reasonably, the training effect can be guaranteed and the modeling time and cost can be saved.

Description

technical field [0001] The invention relates to the field of general aviation / helicopter operation support, in particular to a method and system for modularizing a helicopter earthquake rescue simulation scene. Background technique [0002] Earthquake is a sudden and extremely destructive natural disaster. After an earthquake occurs, efficient and rapid response is very important for reducing earthquake hazards. In order to achieve efficient and rapid earthquake rescue, continuous training of rescue personnel is required. [0003] Because the real earthquake scene is difficult to reproduce, and the danger of exposing rescuers to the real training environment is extremely high, virtual simulation training is generally used. Virtual simulation training is not only safe but also low in cost, so it has been more and more widely used in the field of training. [0004] At present, relatively mature virtual training systems include: the Advanced Disaster Management Simulation (AD...
