摘　　要：为了降低核电站地下综合管廊在一些潮湿环境中因水汽导致感烟火灾探测频繁误报问题,对现场情况及当前感烟火灾探测技术做了充分的调研分析。现基于双波长感烟探测及烟雾算法识别等技术开发一套适用于高湿环境下的双波长感烟火灾探测器,并通过相关试验验证该探测器在高湿环境中的适用性及稳定性。结果表明该感烟探测器在高湿环境中烟雾识别算法可成功剔除水汽产生的干扰信号,避免误报情况的发生,实现可靠稳定的运行效果。Moist air in underground utility tunnel below the nuclear stations may affect smoke detectors that would send out false fire alarms.Considering this condition,this paper makes field investigations and analyzes the technologies applied in fire detector system,and then develops a new detector system that suits to be installed in heavy moisture condition under the guidance of double-waved smoke detectors and dynamic calculating recognition.After that,some tests were taken to ensure its practicability in particular environments.The result shows that the new detector system could recognize the special signal of fire and smoke while filter vapor interference,so as to ensure the fire warning system running stably and accurately.
