Earthquake rescue simulation drilling system and design method thereof

Abstract

The invention discloses an earthquake rescue simulation drilling system which comprises 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 training evaluation subsystem, a virtual training recording and playback subsystem, a training resource management subsystem and a multi-point audio communication subsystem. The design method comprises the following steps: step 1, a plan loading and operation control process is carried out; step 2, the scene real-time rendering subsystem receives the plan file information from a plan generation subsystem and establishes a local rendering object; then, the three-dimensional scene real-time rendering subsystem receives a human-related action instruction from a virtual human control member VH, and simulation is carried out according to the content of instruction information; step 3, dynamics calculation is performed; and 4, data communication is performed among the director group, the drill group and the evaluation group by adopting a communication interface.

Description

technical field [0001] The invention belongs to the technical field of emergency training, in particular to an earthquake rescue simulation drill system and a design method thereof. Background technique [0002] Earthquake is a sudden and extremely destructive natural disaster. Using the existing technology of computer simulation reality, through the simulation modeling method and reproduction technology of the earthquake disaster process, a virtual earthquake disaster site environment close to the real is created for the The research on the earthquake disaster scene plan editor and the real-time rendering subsystem of 3D visual scene in the earthquake emergency rescue and disposal drill platform lays the foundation. 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 si...

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".
