Distributed virtual simulation earthquake emergency drilling system

Abstract

The invention discloses a distributed virtual simulation earthquake application drilling system. The system comprises an earthquake environment resource database, an immersion display and interaction subsystem, an escape plan generation subsystem, a modeling and simulation subsystem, a three-dimensional scene real-time rendering subsystem, a virtual drill evaluation subsystem, a virtual drill recording and playback subsystem and a communication subsystem. A distributed interactive simulation technology and a virtual environment modeling method are used in an earthquake emergency drilling technology, and an HLA high-rise system frame structure is used as a specification followed by distributed interactive simulation. The earthquake disaster scene simulation and earthquake emergency drilling virtual simulation drilling technology is subjected to technology development of interaction between necessary equipment and objects in a virtual environment, and the feeling and experience of immersion in a real environment are generated, so that the on-site feeling of a trainee is enhanced; and the rapid response and emergency disposal capabilities of earthquake emergency management personnel are improved.

AI Technical Summary

Problems solved by technology

However, the emergency drill system in the prior art still focuses on carrying out actual combat simulation drills, and due to the complexity of the earthquake scene, the simulated disaster scene area has certain limitations, and the calculation amount of the simulated disaster scene drawing is large, which cannot meet the requirements of real-time simulation drills. Require

In addition, due to the lack of distributed technology, the interoperability of simulation applications proposed for simulation cannot be met to achieve seamless links between different types of simulation applications, such as real-time continuous system simulation based on equal time steps, actual The C4I system is integrated into a distributed interactive comprehensive environment

Simulation cannot be organically combined with virtual reality equipment, and it cannot form mutual coupling in time and space. Participants can freely interact with the environment to complete the goal of the exercise.

At present, there is no mature application system in the world, which can use advanced 3D visualization, virtual simulation technology and computer network to "connect" the software and hardware equipment scattered in different places with relevant personnel, and form a disaster-stricken environment in the artificially synthesized "disaster-affected environment".
