高灵敏度红外图像式烟雾相对浓度测试的研究和实现

The Research and Realization of High Sensitive Infrared Imagic Relative Smokemeter

为准确可靠的对大空间的早期火情做出监测 ,避免大规模火灾的发生 ,对烟雾情况进行研究 ,研制了图像式的高灵敏度红外烟雾相对浓度测试仪。该测试仪利用了烟雾粒子的光衰减原理工作 ,接收主动的矩阵式红外发射源发出红外光 ,将获得的CCD图像信息传送到计算机 ,利用相邻帧平均滤波进行数字滤波处理 ,插值形成浓度的二维平面投影图 。

In order to monitor and forcast the early fire in large room,and research the movement of smoke, we invented this image high sensitive infrared smokemeter. It uses the light attenuation made by the smoke mites theorem. And the light source is a matrix of infrared diodes. The images captured are processed with boder upon frames average filter. Then interposed into the two dimension thickness projection. Continuously monitor will generate dynamic pictures.
