Abstract
The invention provides a conveyor belt anomaly detection system which comprises a camera, a first image processing unit, a second image processing unit and an alarm device, wherein the camera is arranged above a conveyor belt, and is used for shooting a section of the conveyor belt; the first image processing unit carries out equalization on an image shot by the camera so as to obtain an equalized image; the second image processing unit carries out graphical numeric comparison on an image currently shot by the camera and the equalized image obtained from the first image processing unit; and the alarm device is connected with the second image processing unit, and when a graphical numeric comparison result of the second image processing unit is greater than a threshold, the second image processing unit indicates the alarm device to raise the alarm. According to the invention, a novel image comparison technology is applied to the field of conveyor belt anomaly detection. Once a situation that a block image of a conveyor belt has a large deviation is found, the conveyor belt anomaly detection system can provide early warning timely.
Description
Technical field
The present invention relates to the belt conveyor field, relate in particular to a kind of belt conveyor abnormality detection system.
Background technology
Belt conveyor with traction piece generally comprises traction piece, load-carrying element, actuating device, tightening device, change course device and supporting member etc.Traction piece can adopt belt conveyor, tow chain or steel rope in order to transmitting tractive power; Load-carrying element has hopper, carriage or suspender etc. in order to bear material; Actuating device, generally is comprised of electrical motor, retarder and drg (stopper) etc. with power to conveyer; Tightening device generally has two kinds of screw and weight hammer types, can make traction piece keep certain tension force and sag, to guarantee the belt conveyor normal operation; Supporting member can adopt carrying roller, roller etc. in order to support traction piece or load-carrying element.
Belt conveyor is through the unusual conditions such as bulge, wearing and tearing occurring unavoidably after long-term the use.This class error state is in case outburst will cause great destruction to whole transport system for the belt conveyor fracture.Particularly, for the belt conveyor transport systems of some longer distance, the fault of belt conveyor fracture and so on often causes great property even personnel's damage.
Therefore, industry is needed a kind of actv. solution badly and is overcome above-mentioned technical matters of the prior art.
Summary of the invention
The present inventor's combination research and development experience has for many years been developed a kind of belt conveyor abnormality detection system.
Particularly, the invention provides a kind of belt conveyor abnormality detection system, comprising:
Camera is arranged at the top of belt conveyor, and described camera is taken a section of described belt conveyor;
The first graphics processing unit, the image taken to described camera averages, to obtain an equalization image;
The second graphics processing unit, with described camera current shooting to image with carry out graphical numeric ratio from the equalization image of described the first graphics processing unit; And
Warning device is connected with described the second graphics processing unit,
Wherein, as the graphical numeric ratio result of described the second graphics processing unit during greater than a threshold value, described the second graphics processing unit indicates described warning device to give the alarm.
According to a preferred embodiment of the present invention, in above-mentioned belt conveyor abnormality detection system, described graphical numeric ratio comprises: with described camera current shooting to image and same group of intrinsic image of described equalization image make up, to generate corresponding intrinsic image set of weights; And with the intrinsic image set of weights that obtains with respect to described camera current shooting to image and described equalization image compare, to produce corresponding comparative figure.
According to a preferred embodiment of the present invention, in above-mentioned belt conveyor abnormality detection system, described combination comprise with described intrinsic image to described camera current shooting to image and described equalization image carry out convolution.
According to a preferred embodiment of the present invention, in above-mentioned belt conveyor abnormality detection system, described graphical numeric ratio before, described the second graphics processing unit first with described camera current shooting to image and described equalization image carry out normalisation.
According to a preferred embodiment of the present invention, normalisation described in the above-mentioned belt conveyor abnormality detection system be current shooting to image and described equalization graphics standard to turn to average be that the zero-sum variance is one.
The present invention is applied to the image comparison techniques of novelty in the belt conveyor abnormality detection field.In case find the tile images generation relatively large deviation of belt conveyor, then can in time provide early warning.Therefore, the present invention can avoid because great property and the personal damage that the problem of belt conveyor fracture and so on causes.
Should be appreciated that the above generality of the present invention is described and the following detailed description all is exemplary and explanat, and be intended to the further explanation that the invention provides for as claimed in claim.
Description of drawings
Accompanying drawing mainly is be used to providing the present invention further to be understood.Accompanying drawing shows embodiments of the invention, and plays the effect of explaining the principle of the invention with this specification sheets.In the accompanying drawing:
Fig. 1 schematically shows the basic structure of belt conveyor abnormality detection system of the present invention.
The specific embodiment
Discuss a plurality of embodiment of the present invention in detail below in conjunction with accompanying drawing.
