Abstract
The present disclosure provides an experiment platform for simulating fire in an underground traffic conversion channel, including: a model body configured to simulate fire in the an underground traffic conversion channel; a burner connected to the model body and configured to generate smoke; and a smoke imaging system including laser sheet light sources and image recording devices configured to record smoke distribution images. The laser sheet light sources are in the model body, and plane laser light emitted by the laser sheet light sources is parallel to a flow direction of the smoke. The image recording devices are in one-to-one correspondence to the laser sheet light sources and are arranged outside an observation window of the model body. One laser sheet light source and one image recording device corresponding thereto each have a filter configured to filter out laser light of a same wavelength.
