The invention discloses an industrial Internet-oriented fault early warning method and device. The method includes: modifying the early warning threshold of the early warning model according to the early warning information sent by the early warning model, the actual failure of the industrial equipment and the actual shutdown; the adjustment formula of the early warning threshold XT is: XT=(X2+X3) / 4+(X4 ×W4+X1×W1) / 2 Among them, XT represents the early warning threshold; X1, X2, X3 and X4 respectively represent the centroid value of the predicted error class, the centroid value of the accurately predicted fault class, the centroid value of the accurately predicted normal class, and the predicted error class. The centroid value of the accurate class; W1 and W4 represent the weight coefficient of the predicted wrong class and the weight coefficient of the predicted inaccurate class, respectively. The method effectively balances fault warning and production efficiency, and enables safe and efficient operation of industrial equipment.
Description
technical field [0001] The present invention relates to the technical field of industrial Internet, in particular to a fault early warning method and device for industrial Internet. Background technique [0002] In the process of industrial production, it is necessary to monitor the operation status of industrial equipment in order to find and eliminate problems in time. With the deepening of industrialization, people put forward higher requirements for the operating efficiency of industrial equipment, hoping to realize monitoring and early warning of industrial equipment, and reduce production stagnation caused by industrial equipment failure. [0003] The current early warning method is the edge model deployment method, that is, the locally trained fault early warning model is deployed on the edge cloud, and then the production data is connected in real time, and the fault early warning is realized based on the real-time production data. This early warning method has the ...
