大空间建筑火灾防治问题的探讨

Discussion about Large Space Fire Prevention

介绍了大空间建筑物早期火灾探测问题,并提出了相应的解决途径,指出建筑电气在大空间建筑火灾防治中占有重要地位。重点介绍了光截面感烟探测器和双波段图像型感焰探测器的工作原理、技术特点和典型应用,以及光纤光栅感温火灾探测器的工作原理、技术特点及应用场所,以对火灾防治提供借鉴。

The early fire detection in large space structures was introduced and the settlement was provided. The importance of the building electrical in the large space fire prevention were pointed out. The working principle, characteristics and typical applications of optical cross section smoke detectors and a dual-band image-based sense of flame detector were introduced. The working principle, characteristics and application areas of optical fiber grating temperature fire detector were also introduced. It could provide references for fire prevention.
