摘　　要：针对舰船舱室环境采用吸气式感烟探测器设计火灾探测报警系统,用于舰船电气阴燃火的早期探测,同时对于设计结果进行了实火试验,将响应时间与传统点型探测报警系统的响应性能进行比对,依此对火灾探测报警系统的响应时间能进行了分析,得出该火灾探测报警系统的有效性和适应性。并开展了保护部位数值模拟仿真计算。通过实火试验和仿真计算的比对分析,检验了仿真计算方法与理论的适用性,采用仿真计算对设计的合理性和有效性进行系统性能评估,预计系统中最不利点在既定火灾场景下的火灾探测报警响应时间。The fire detection and alarm system is designed by aspirating smoke detector for ship cabin environment,for early detection of electrical smoldering fire. At the same time, the real fire test is carried out for the design results. The response time and the comparison results with the traditional detection and alarm system are obtained. Base on this,the response time performance of fire detection and alarm system is analyzed, the effectiveness and adaptability of the system are obtained. The numerical simulation of the protection part is carried out.Through the comparison and analysis of real fire test and simulation calculation,the applicability of the simulation method and theory is verified. Simulation calculation can be used to evaluate the rationality and effectiveness of the design, and predict the response time of fire detection and alarm of the most unfavorable point in the system under the given fire scenario.
