Thermal inductance feedback device and method for virtual fire-fighting drilling

Abstract

The invention provides a thermal inductance feedback device and method for virtual fire-fighting drilling. The thermal inductance feedback device used in virtual fire-fighting drilling comprises the steps that firstly, a virtual image is watched in real time through a VR helmet, interaction with a virtual scene is conducted in real time through keys and body movements, and in a real scene, a useris located in the action range of the thermal inductance feedback device; secondly, data such as heat and angles generated by virtual flames, smoke and the like in the virtual scene are transmitted toa control unit of the device in real time, the control unit drives the thermal inductance feedback device to adjust the position, the angle and the heat intensity through data conversion, and feelings such as heat and wind act on people in the real scene. According to the method, the problem of single feedback form in virtual fire-fighting drilling is solved, and thermal inductance feedback is effectively carried out on the user. According to the device, all parts of the device can be accurately controlled through data, a flexible thermal feedback form is realized, and a new device and methodare provided for thermal feedback in a virtual simulation scene.

Description

technical field [0001] The invention relates to a virtual fire drill, in particular to a thermal feedback device and method for a virtual fire drill. Background technique [0002] According to international reports, at home and abroad, in fires, the death toll caused by smoke and heat waves is as high as 2 / 3 of the total death toll. Therefore, the visualization of heat waves and heat flow tests in the virtual environment is a key issue in effectively reducing fire casualties. Traditional fire drills train fire drill knowledge and gain experience at the practical level, but they will generate high social and economic costs, and even cause casualties. Contrary to this potentially risky drill, there is a low-cost, high-safety, high-simulation, and repeatable virtual reality (VR) drill system, through which people can conduct evacuation or rescue training in a virtual scene. Some VR-based fire training systems have been developed. [0003] At present, thermal feedback devices...

AI Technical Summary

Problems solved by technology

[0003] At present, thermal feedback devices and methods used for virtual fire drills are mainly mechanical passive acquisition and feedback. Researchers have developed a large number of thermal acquisition devices and thermal feedback devices, most of which have complex structures and large equipment volumes. The cost is high, the user experience is not good, resulting in poor results, and it is impossible to get good intelligent feedback

Another type of feedback equipment mainly collects information mechanically, and analyzes the mixed gas and air moisture in the collected air. However, the collection of hot gas is inaccurate and the structure is complex, so it cannot effectively provide thermal feedback.
