| 摘 要： | 从光全散射的基本原理出发，提出了一种多波长激光全散射法探测火灾烟雾的浓度、平均粒径和粒径分布的方法。该法用于早期火灾的探测报警，可对火灾烟雾和干扰的类型进行识别，能克服传统的光电感烟探测技术存在的缺点，大大提高火灾探测的可靠性和灵敏度。

| Abstract: | Based on the principle of light total scattering, a method,named multiwavelength laser total scattering method,to detect the concentration,the mean particle size and distribution of the fire smoke is proposed in this paper. This method can be used for early fire detection and alarm, through which the type of both smoke and interference can be recognized. Thus the disadvantage of traditional photoelectric smoke detection technique can be avoided,and the reliability and the sensitivity of fire detection are greatly improved. |
