中文摘要: |
从辐射传热的角度 ,同时考虑照明条件下的火灾烟雾与环境背景中其他物体的辐射 ,采用信 /噪比处理方法 ,对火灾烟雾光学探测原理进行了数学分析。分析指出 :火灾烟雾光学探测必然分为散射型和透过型两种原理类型 ,以及存在着四种技术原理. |
英文摘要: |
Based on radiation heat transfer and considering the effect of factitious illumination and the radiation of background objects under natural illumination , the paper testifies that the optical detection approach must be divided into scattering style and transmission style via SNR Mathematic analysis, In addition, four corresponding technology principles are also analyzed in this paper. |
