Research On The Influence Of Remote Interaction Mode Of Dynamic Spatial Information On The Decision-making Of Route Finding In High-rise Building Fire

With the rapid economic growth and the continuous expansion of the city scale,high-rise buildings have gradually become the mainstream of today's buildings.Rapid urban development has brought great pressure to the fire safety.The disadvantages of high-rise building fire,such as rapid fire spread,more smoke,difficult evacuation and fire fighting,make it very difficult to evacuate and extinguish the fire.At present,the research on evacuation and fire fighting and rescue of high-rise office buildings in China is in the initial stage,and the research on the front-line firefighters' road finding behavior needs corresponding theoretical support,so the research in this paper has important theoretical significance and practical value.The subject of this paper comes from the Beijing natural fund(9172008).It mainly carries out the questionnaire survey on the way finding behavior of firefighters in China,analyzes the contents of foreign literature,and develops the performance of the long-distance interaction mode in high-rise building fire based on the theory of spatial cognition,spatial reference frame,interactive mode of spatial information,combined with the field and unity3 d simulation software Influence the research of the subject.This paper discusses the theoretical basis and empirical research of the interaction mode of firefighters in multi-layer and dynamic environment.This research mainly includes four parts: 1.The investigation of firefighters' road finding behavior.2.Research on the cognitive framework of human space in high-rise buildings.3.The influence of different spatial information interaction modes on the behavior of path finding in fire field.4.The influence of different spatial information interfaces on the behavior of path finding in fire.The research methods include interview research and empirical research.The main results of this paper are as follows: 1.The dynamic space environment in the high-rise building space will make the spatial frame of the Pathfinder change from self reference frame to environment reference frame.2.On the basis of result 1,it is found that in the traditional spatial interaction mode,the spatial interaction mode based on overview map is the most effective compared with voice and video mode.3.From the spatial interaction process of achievement 2 to the spatial object level,it is found that the interaction based on overview map reduces the reference of spatial objects and improves the overall performance of road finding,which is mainly reflected in the overall road finding time is longer and the distance is shorter.At the interactive level,the search time of spatial objects is less and less.It is concluded that in the dynamic high-rise building fire scene,the performance of road finding can be improved by setting up a local overview cognitive object.The findings can provide support for the auxiliary design and research of fire fighting and rescue in China.
