Fire escape simulation system based on VR technology

Abstract

The invention provides a fire escape system based on the VR technology. The system includes VR equipment, an analog room and a computer. The VR equipment chooses an analog scene. The computer generates the coordinate of a virtual fire source point according to the selected analog scene, and a testee wears the VR equipment to enter the analog room. A foot sensor is installed in the analog room, andthe foot sensor includes an X-axis direction sensor and a Y-axis direction sensor for detecting the current position of the testee; a smoke generator, a hot-air blower and a baking board are arrangedin the analog room, the smoke generator is used for simulating the haze effect in the analog scene, the hot-air blower is used for simulating the hot air effect generated around a fire source in theanalog scene, and the baking board is used for simulating the baking effect generated around the fire source in the analog scene; the foot sensor is used for transmitting a detected signal to a controller, the controller calculates the distance between the current position of the testee and the analog fire source, switches and gear numbers of the hot-air blower and the baking board are controlledaccording to the distance, so that the system simulation is closer to a real scene, and the experience feeling of the testee is enhanced.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a fire escape simulation system based on VR technology. Background technique [0002] As one of the key technologies in contemporary society, virtual reality technology has become the focus of information construction research, and the prevention of disasters is closely related to our lives. Combining disaster prevention and visualization technology enables people to experience disasters in person. To deepen people's deep understanding of disasters, virtual reality technology has a wide range of applications in many aspects. [0003] Disasters such as earthquakes and fires have their particularities. It is difficult to experience the authenticity of accidents with real experiments in real life, so it is difficult to learn how to deal with emergencies through experience education. Therefore, it is particularly important to use virtual reality technology to simulate the fi...
