Abstract:

In order to control the fire and explosion risk target of gas station, an unsafe behavior detection model of gas station based on YOLO-V3 algorithm was proposed by combining accident statistics and fault tree analysis,. Firstly, on the basis of collecting 90 gas station fire and explosion accidents, the ignition sources of gas station fire and explosion accidents were statistically analyzed. Secondly,. the fire and explosion fault tree of gas station was constructed, the structural importance of each basic event was calculated, and the unsafe behavior with high risk of gas station was determined. Then, the image data of unsafe behavior of gas stations were collected by field collection and simulation, and the image data set of unsafe behavior of gas stations was constructed by data enhancement method. Finally, based on the deep learning method, the unsafe behavior detection model of gas station was constructed, and the final model was obtained after 1000 training iterations. The results show that the unsafe behaviors that cause fire and explosion accidents in gas stations mainly include smoking, calling and so on. The average detection accuracy of the trained detection model for smoking, calling and normal behavior detection categories on the test set is 67%, 85% and 77%, respectively, and the average detection accuracy of the model is 84%.
