Abstract: This paper presents the structural characteristics and fire detection and suppression research issues of large space buildings (including high large space buildings and large flat space buildings). The current research status of fire detection, suppression, and smoke control strategy is clarified, and suitable detection and suppression technologies are proposed for large space buildings. Finally, the frontier issues, including research on more precise detection and positioning technologies, efficient smoke control strategies, and the development of new fire protection and smoke control technologies, are pointed out.

Key words: large space, large flat space, fire detection, fire suppression, smoke exhaust
