Fault diagnosis device based on common information and special information of running video information for electric-arc furnace and method thereof

A fault diagnosis method based on common information and special information of running video information for an EFMF (electrical fused magnesium furnace), comprising steps of:

• 1) arranging six cameras, wherein three of the six cameras are respectively arranged at relative positions of three electrodes above the EFMF and aim at the electrodes of the EFMF, so as to monitor a furnace eruption fault;
• rest of the six cameras are symmetrically arranged around a furnace body by a 120 degree difference and aim at the furnace body, so as to monitor occurrence of a furnace leaking fault;
• 2) obtaining video information by the six cameras and sending the video information to a control center;
• then analyzing the video information by a chip of the control center;
• wherein in order to simplify a difficulty of analysis and improve a real-time performance of video data analysis, multi-view video summarization technology is introduced, so that industrial process monitoring based on running video information is able to be realized;
• specifically, a multi-view-based fault diagnosis method is used by the chip, comprising steps of:
• 2-1) comparing a difference between two consecutive frame histograms for shots segmentation;
• 2-2) computing a set of characteristic values for each shot obtained by the step 2-1), and then computing color, texture, and motion vector information;
• finally, evaluating shot importance via entropy;
• 2-3) clustering shots together by calculating similarity, wherein calculation of the similarity of the shots comprises the similarity of the shots in a mono-view and correlation of the shots in different views;
• 2-4) generating and optimizing a multi-view video summarization with a multi-objective optimization model;
• wherein the shot in the shot cluster is either reserved or abandoned so as to obtain the multi-view video summarization with a less number and a shorter length of the shots but contains more fully video information;
• and
• 2-5) providing fault detection and diagnosis;
• and
• 3) displaying results of the fault detection and diagnosis on a host computer inter face of the control center.
