Abstract

The invention discloses a method and system for detecting the working state of ball mill equipment through monitoring video. The method includes: setting a marking unit that can rotate synchronously on the outer surface of the ball mill cylinder; The mark rotation video in which the cylinder rotates synchronously around its axis uses image recognition processing to identify the mark unit in the mark rotation video in real time, and converts it into a periodic correlation coefficient curve; detects the total number of rising edges of the correlation coefficient curve per unit time, Calculate the rotational speed, rotational angular velocity and rotational period of the ball mill cylinder according to the total number of rising edges; determine the current working state of the ball mill according to the relationship between the actual value and the normal value of any parameter of the rotational speed, rotational angular velocity and rotational period of the ball mill during work, And deal with it when it is abnormal. It can realize the automatic, real-time and accurate monitoring of the working state of the ball mill.

Description

technical field [0001] The invention relates to the field of detection of the working state of a ball mill, in particular to a method for detecting the working state of a ball mill through monitoring video. Background technique [0002] In the working environment of the existing ball mill equipment, in order to improve the production efficiency and reduce the cost of replacing the inner wall liner of the ball mill, it is necessary to control the production process by adjusting the speed of the ball mill according to the working state of the ball mill. The working state of the ball mill can be divided into low speed (angular velocity ω<ω 1 ) state, normal speed (angular velocity ω 1 ≤ω≤ω 2 ) state and high speed (angular velocity ω>ω 2 )state. Figure 1 to Figure 3 It is a schematic diagram of the three working states of the ball mill, including the throwing point and landing point of the grinding medium ball 10 (hereinafter referred to as the medium ball) and the ma...
