Abstract: In order to achieve the rapid processing of heterogeneous information at fire accident scenes, the characteristics of timeliness, uncertainty and complexity of information at disaster scenes are addressed. On the basis of determining the types of decision information, the relevant theories and methods based on the edge computing method are used to select the corresponding terminal sensing devices for different types of decision information and introduce the relevant data processing techniques; the inherent mode of current data calling is improved to effectively reduce the impact of data access latency and solve the data selection problem of insufficient capacity when storing edge data.

Key words: fire accident scene, edge computing, heterogeneous data, edge storage
