摘　　要：介绍国内火灾自动报警设计规范的各种探测器选择方法,根据防火性能化分析原理,针对某成品库大空间建筑屋面取消喷淋的设计方案,为保证火灾自动报警探测及时可靠,确保建筑的耐火极限时间,采用美国Fire Dynamic Simulation软件,通过火灾热动力过程和探测器启动的有限元数值模拟,对成品库大空间建筑的火灾及探测进行性能化分析;通过优化设计采用线型红外光束感烟火灾探测器设计,使火灾探测报警系统既安全可靠又经济合理。Introduce the various choice methods of fire detector in Chinese fire automatic alarm design criterion.Based on the analytic theory of fire resistant performance and the design solution of canceling the sprays in a big space warehouse,in order to ensure the immediacy and reliability of the fire detector,and the fire resistance time limit of the building,a performance-based fire protection for the warehouse is analyzed by using Fire Dynamic Simulation American software based on the fire dynamic and fire detectors' FEM numerical simulation.Through optimizing design,choose the linear infrared smoke detector to ensure the fire detection system's safety and accuracy.
