Image detection method of combustible dust cloud

Abstract

In recent yearsꎬ production accidents caused by dust explosion occur frequentlyꎬ and on ̄line detection and early warning of dust cloud concentration in dust gathering places has become a key means to control dust explosion. Howeverꎬ installation and identification of dust concentration sensors were limited in large space where dust cloud gathers. In order to address thisꎬ combustible dust cloud recognition method based on deep learning was proposed. End ̄to ̄end detection and identification of explosive dust cloud were conducted by using CNN ̄based Faster R ̄CNN model. Thenꎬ a standard concentration image database was established to verify experimental results. The results show that Faster R ̄CNN model can effectively detect and identify explosive dust cloudsꎬ and it has high recognition accuracy.
