Area-array cameras are arranged on the portions, close to the light sources, of the supporting frame. A rotary encoder is arranged on the side face of one roller and connected with a synchronizer. The synchronizer is connected with an image processing platform and the area-array cameras. The image processing platform is connected with the area-array cameras through exchangers and is connected with a control cabinet. The belt tearing detection device based on image processing is convenient to maintain and high in stability, the reliability of a detection result is high, the problem of a high false detection rate of current sensing detection is avoided, and complete image scanning without repetition or omission is achieved.
Description
Technical field
The invention belongs to belt tearing detection technique field, be specifically related to the device for detecting belt tearing based on image procossing.
Background technology
Belt conveyer continuative transport ability is strong, operating efficiency is high, be easy to realize automatic control, has been widely used in the Coal Transport of the enterprises such as harbour, mine, power plant.Existing long belt conveyor extensively adopts steel rope core to transport its pulling strengrth of raising, but the ability of its longitudinal anti tear is not improved, and easily causes longitudinal tear.Steel cord conveyor is the main artery of factories and miness production and transport, once cause broken belt, will bring great direct and consequential damage.In China, mining steel core ribbon longitudinal tear accident happens occasionally, and therefore, is necessary very much to develop a kind of reliable and practical wire rope for mining core conveyer belt longitudinal tear monitored control system, realizes timely, failure-free monitoring to steel core band longitudinal tear fault.Prior art many employings contact-sensing metering system detects, but also there is the deficiencies such as false drop rate is high, plant maintenance trouble, cannot ensure the operation that equipment is long-term, stable.The present invention adopts machine vision and image processing techniques, the mode of indirect inspection, and plant maintenance is convenient, and stability is high, and reliability is strong.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of that adopt machine vision and image processing techniques indirect inspection, that plant maintenance is convenient, stability is high, testing result reliability is strong device for detecting belt tearing based on image procossing.
For achieving the above object, the present invention is by the following technical solutions: a kind of device for detecting belt tearing based on image procossing, mainly comprise belt, conveyer, described conveyer is provided with bracing frame, roller bearing, roller, bracing frame below described belt is provided with light source, light source place is provided with area array cameras, described roller side is provided with rotary encoder, described rotary encoder is connected with synchro, described synchro respectively with image processing platform, area array cameras is connected, described image processing platform is connected by exchange with area array cameras, described image processing platform is connected with control housing.
Further, described belt is set to groove structure.
Further, described area array cameras is provided with 2, and optical axis intersection is also respectively horizontal by 45° angle.
Further, described light source and area array cameras outer setting have shade.
Further, described light source arranges LED area array light source.
Further, this detecting device is arranged at below feed opening.
The technical solution adopted in the present invention has following beneficial effect: the present invention adopts contactless mode to detect belt defect, light source is coordinated by area array cameras, after collection site belt picture, again according to image processing techniques, analyze the defects such as belt tearing, avoid current sensor and detect the problems such as false drop rate is high.Meanwhile, adopt rotary encoder to add synchro and control camera candid photograph frequency, making camera scanning mate belt running velocity completely, realizing without repeating, exhaustively complete image scanning.Feed opening be belt tearing accident multiplely, detect near feed opening, can deal with to accident fast, reduce causality loss.Annex detects belt tearing, and present device of setting out is easy to maintenance, stability is high, testing result reliability is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is connection schematic diagram of the present invention.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of device for detecting belt tearing based on image procossing, this detecting device is arranged at below feed opening 1, mainly comprise belt 2, conveyer 3, described belt 1 is set to groove structure, described feed opening 1 is arranged at above belt 2, described conveyer 3 is provided with bracing frame 4, roller bearing 5, roller 6, bracing frame 4 below described belt 2 is provided with light source 7, light source 7 place is provided with area array cameras 8, described roller 6 side is provided with rotary encoder 9, described area array cameras 8 is provided with 2, and optical axis intersection is also respectively horizontal by 45° angle, described light source 7 has shade with area array cameras 8 outer setting, described light source 7 is set to LED area array light source.
As shown in Figure 2, described rotary encoder 9 is connected with synchro 10, described synchro 10 is connected with image processing platform 11, area array cameras 8 respectively, and image processing platform 11 is connected by exchange 12 with area array cameras 8, and described image processing platform 11 is connected with control housing 13.
In use, be feed opening 1 above belt 2, supplied materials drops on above belt 2 by feed opening 1 in the present invention, and belt 2 is arranged on roller bearing 5 followed by conveyer 3 operates, and raw material transport is passed to appointed place.Rotary encoder 9 is installed in roller 6 side of described conveyer 3, rotary encoder 9 operates with belt 2, synchro 10 is connected with rotary encoder 9, area array cameras 8, image processing platform 11, synchro 10 is according to the speed of operating speed, and the synchronous area array cameras 8 that triggers gathers the surperficial picture of belt 2.Due to the transportation characterization of belt 2, adopt groove design, single area array cameras 8 cannot gather complete belt 2 surface image, and the present invention adopts two area array cameras 8, and optical axis intersection is also installed horizontal by 45° angle respectively, ensures to gather full picture data.Light source 7 is arranged near area array cameras 8, for area array cameras 8 provides illumination, eliminates the impact of natural daylight, ensures that the picture luminance that area array cameras 8 gathers is stable, evenly reliable.Image processing platform 11 is connected by exchange 12 with area array cameras 8, and by IP address, access plane array camera 8, obtain the picture of each area array cameras 8, after image processing platform 11 gathers picture, overlapping region removed by the picture first gathered by two area array cameras 8, merge, analyze through a series of images treatment technologies such as Image semantic classification, defects detection, feature calculation again after merging, finally according to defect characteristic, judge whether to there is belt tearing or other defect.Image processing platform 11 can adopt ARM or DSP disposable plates, relative industrial computer, and low price is stable.Testing result is sent to control housing 13 by image processing platform 11, and the chain startup and stop that the controlling quantity at control housing 13 internal condition scene adopts controller or PLC to realize belt 2 controls, and system, once the appearance of belt 2 tearing defect be detected, shuts down automatically.
