The invention relates to the technical field of dry quenching, in particular to a dry quenching abnormal material level judgment method which comprises the following steps: data loading and preprocessing: setting an abnormal detection threshold: calculating an abnormal upper limit value and an abnormal lower limit value based on statistical distribution of a coke loading rate; key parameters are initialized, wherein a backtracking step number threshold value and a material level abnormity judgment threshold value are set; and anomaly detection and classification: judging whether the coke loading rate exceeds an abnormal upper limit value or is lower than an abnormal lower limit value point by point from the latest time point to the front, and identifying an abnormal sequence, a material suspension phenomenon and a material collapse phenomenon according to a judgment result. The method has the advantages that the key parameters of the coke loading rate and the material level change rate are integrated, and the dynamic abnormal threshold value is set based on statistical distribution, so that false alarms caused by data noise of a single sensor and instantaneous interference are effectively reduced; and in combination with a reverse anomaly backtracking mechanism, an abnormal mode (such as material suspension and material collapse) with time sequence characteristics can be identified, the missing report is reduced, and the real anomaly capture capability is improved.

The present application relates to a method and system for identifying gangue utilization, and relates to the field of ore sorting. The method includes obtaining an X-ray image and a first color image of each material on a main conveyor belt, determining the density of each material based on the X-ray image, determining the three-channel color value of each material based on the first color image, and determining the probability that each material is gangue based on the density and the three-channel color value. If there is an abnormal material with a probability within an abnormal probability interval, a manipulator is controlled to grab the abnormal material and determine the resistance value of the abnormal material. The probability that the abnormal material is gangue is corrected based on the resistance value to obtain a corrected probability. If the corrected probability reaches a preset probability threshold, the manipulator is controlled to transport the abnormal material to a first preset position so that a high-pressure airflow injection device pushes the abnormal material to a gangue collection area. The present application can more accurately separate gangue from materials and improve the separation effect.
