[0090] Example: In this example, a typical chemical hazard environment is set as a scenario for the disposal of a highway tank truck leakage accident, which is mainly used to simulate the following training scenarios:
[0091] 1. Introduction to the training background: In the environment of the expressway scene, chemical toxic gas is generated after the leakage of the tank truck transporting hazardous chemicals. The rescuers conduct reconnaissance at the scene, operate the toxic gas detector to measure the concentration, and delineate the hazardous range of each hazardous concentration and Finally control the source of danger (plugging).
[0092] 2. Virtual environment construction: carry out chemical rescue and virtual reality (VR) simulation training for the disposal of chemical leakage accidents of expressway tank trucks. Using unity3d to build a virtual environment, including: tanker models, highways, construction areas, and terrains such as rivers, rocks, and vegetation....
