Baffle lifting height monitoring device and method based on image processing

Abstract

The invention relates to a baffle lifting height monitoring device and method based on image processing. The device includes a baffle disposed at an ore exit of an ore bin. The baffle is driven by a baffle driving motor. The baffle lifting height monitoring device is disposed on a working platform of at the ore exit of the ore bin, and includes a box body, a dial plate disposed in the box body, aconnecting rod lifting device, high-definition photographing equipment and a monitoring system. The monitoring method includes image collection, image processing, calculation of measured lifting height H and lift height adjustment. The device and the method have the advantages that the high-definition photographing equipment and an embedded image processor are employed to replace detection and control methods of the prior art on the baffle height, the high-definition photographing equipment is vertically shined on the dial plate, an image of an included angle, which is between a connecting rodand a negative direction of an x-axis and is obtained by angle changing the connecting rod and the dial plate is an image of an angle theta; and a structure is simple, operation is convenient, and accuracy of height discrimination is improved.

Description

technical field [0001] The invention belongs to the technical field of object monitoring and positioning, and in particular relates to a device and method for monitoring the lifting height of a baffle based on image processing. Background technique [0002] The ore bin valve is mainly controlled by the drive motor to control the opening height of the mechanical baffle to control the amount of ore feeding. Therefore, it is necessary to accurately detect and control the opening height of the mechanical baffle of the mine bin valve. So far, many research institutions at home and abroad have done a lot of work in the field of baffle movement detection and control, but the detection technology is too complex and cumbersome, and the cost is high. At present, the method of using electrical sensing to detect the height of the baffle is relatively common. Due to the harsh outdoor environment, there is a certain probability that the feedback signal will fail, which will lead to produ...

So far, many research institutions at home and abroad have done a lot of work in the field of baffle movement detection and control, but there are problems that the detection technology is too complex and cumbersome, and the cost is high

At present, the method of using electrical sensing to detect the height of the baffle is relatively common. Due to the harsh outdoor environment, there is a certain probability that the feedback signal will fail, which will lead to production accidents. Therefore, it is urgent to adopt another low-cost and accurate measurement method. The method supplements or replaces the traditional detection method, and the distortion of the detection data is likely to cause errors in industrial control.
