灰尘、水雾等干扰气溶胶易导致散射式感烟火灾探测器的误报,为解决火灾烟与干扰源的识别问题,介绍基于气溶胶光散射特性研究实验平台、干扰气溶胶散射研究实验装置,通过对灰尘、水雾、香烟和广谱火灾烟散射特征属性的研究,并依据实验确定粒子的识别算法,实现对火灾烟与典型干扰气溶胶的有效识别。
Dust, water fog and other interference aerosols easily lead to false alarms of scattering smoke detectors. In order to solve the problem of recognizing fire smoke and interference sources, an experimental platform based on aerosol light scattering properties is introduced. The experimental device of interference aerosol scattering Through the research of dust, water fog, cigarette and smoke properties of broad-spectrum fire smoke scattering, the particle recognition algorithm was determined experimentally to realize the effective recognition of fire smoke and typical interference aerosol.
