Method and system capable of achieving detection of work state of ball mill equipment through surveillance video

Abstract

The invention discloses a method and system capable of achieving detection of a work state of ball mill equipment through a surveillance video. The method comprises the steps that a mark unit capableof synchronously rotating is mounted on the position of the outer surface of a ball mill cylinder, a camera is mounted outside the ball mill cylinder, a mark rotating video of synchronous rotating ofthe mark unit around the axis of the cylinder along with the cylinder is clearly recorded, image recognition processing is used for real-time recognizing of the mark unit in the mark rotating video, conversion into a periodic related coefficient curve is achieved, the total number of rising edges of the related coefficient curve in the unit time is detected, according to the total number of the rising edges, the rotating speed, the rotating angular speed and the rotating period of the ball mill cylinder are calculated, according to the size relation between the actual value of any one parameter of the rotating speed, the rotating angular speed and the rotating period of a ball mill during work and the normal value, the current work state of the ball mill is determined, and corresponding treatment is carried out when the ball mill is in the non normal work state. Automatic, real-time and accurate monitoring of the work state of the ball mill can be achieved.

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...
