Paper Abstract

In order to solve the problem of overall measurement of smoke mass concentration field and real-time dynamic measurement, a set of method is designed, which by collecting gray scale information of smoke distribution image, and then calculating the smoke mass concentration. The experimental results show that, under a certain environmental condition, the gray scale of smoke image has a strongly related quadratic linear relationship with the laser backscatter echo voltage at the corresponding position. Moreover, combining the relationship between the laser backscatter echo voltage and the mass concentration of smoke in the same position, the mass concentration of smoke can be calculated by the value of gray scale. The method of the paper refer to, breaks through the limitation of the existing equipment which only can measure the partial mass concentration of smoke, and the method provides a basis for the development of smoke real-time dynamic measurement of smoke.
