Abstract

The invention relates to a gymnasium fire evacuation behavior data collection system based on virtual reality and a collection method thereof. The invention relates to the technical field of building safety and evacuation simulation. A virtual gymnasium three-dimensional building model is built, and a fire smoke visual scene is simulated in the gymnasium model; through a behavior data acquisition module, behavior data of experimenters during movement during fire simulation are acquired, and after simulation is finished, a subjective body strength table (RPE) is used for subjective evaluation of movement intensity; the collected behavior data are analyzed, and movement behaviors under different evacuation postures are determined; basic information, human body posture data, human body motion parameters, the fatigue evaluation grade and the RPE evaluation data of an experimenter are matched, the data are grouped and numbered, the number further comprises an experiment date and an experiment sequence, and the data are stored and stored.

Description

technical field [0001] The invention relates to the technical field of building safety and evacuation simulation, and relates to a virtual reality-based data collection system for gymnasium fire evacuation behavior and a collection method thereof. Background technique [0002] In recent years, the continuous upsurge of national fitness has continuously promoted the rapid development of the sports industry. The number of gymnasium facilities has increased significantly and the frequency of gymnasium usage has increased. As a large public building, the gymnasium is a densely populated place. Once a fire accident occurs, improper evacuation will cause serious consequences. According to a large number of fire cases at home and abroad, most of the casualties caused by fire are caused by smoke. About 1 / 3-2 / 3 of the total number of deaths were directly caused by smoke in the fire. The hazards of fire smoke are mainly manifested in three aspects: toxicity, light reduction and hig...
