Research on spatial keyword query methods for indoor fire emergency response
To enhance the efficiency of indoor fire emergency response,a spatial keyword query method for indoor fire emer-gency response was proposed.Firstly,a new index structure called indoor fire emergency response tree ( IFER-tree) was in-troduced,which can improve the retrieval speed of indoor spatial keywords.Secondly,a pruning method based on IFER-tree was proposed to refine the dataset effectively and reduce the consumption of query time and computational resources.Finally,a path query method for indoor fire emergency response was proposed to quickly identify the shortest escape route taking into account the level of danger.The results demonstrate that the proposed spatial keyword query method can quickly retrieve the optimal path,enhancing the fire efficiency of emergency response.This research outcome provides important reference for per-sonnel evacuation in emergency fire situations,particularly in determining the optimal escape routes and assessing danger lev-els,which can effectively reduce casualties.
