Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Fig. 1 is the system architecture synoptic diagram that the utility model belt deviation monitoring device embodiment is applied to belted electronic balance, and as shown in Figure 1, present embodiment belt deviation monitoring device comprises light source generation module 1, image capture module 2 and data processing module 3.In concrete the enforcement, light source generation module 1, image capture module 2 can be arranged in the same monitoring case.Wherein, light source generation module 1 can be arranged on the top of belt, it can get the light beam that has formed the coordinate effect in the horizontal tangent projection of belt on belt be the coordinate light beam, this coordinate light beam irradiates is on belt, its range of exposures should cover the width of belt, such as this light beam is the cruciform light beam, then two of the mutual square crossing of this cruciform light beam light beams can be respectively as X-axis and Y-axis, then belt about two edge lines wherein optical beam ratio such as the X-axis light beam with this cruciform light beam may be intersected to form two X coordinates, when belt generation sideslip, two X coordinates can change, by analyzing this two degree whether the X coordinate changes and change, just can judge the whether degree of sideslip and sideslip of belt.This coordinate light beam also can be for cruciform be not other shapes, as long as can play similar coordinate effect.Image capture module 2 can be arranged on the top of belt, after light source generation module 1 is got the coordinate light beam that the horizontal tangent projection at belt forms, 2 pairs of these coordinate light beams of image capture module are gathered, wherein, comprised in this image that coordinate judges needed factor, such as two edge lines about belt and coordinate light beam, and this image is transferred to connected data processing module 3; The coordinate light beam that 3 pairs of data processing modules receive is handled, and analyzes the variation of belt formed coordinate on the coordinate light beam, thereby just can judge the whether degree of sideslip and sideslip of belt.
Describe the application principle of the utility model belt deviation monitoring device below in detail with a specific embodiment.In the present embodiment, the coordinate light beam is the cruciform light beam, and light source generation module is to send the cross-shaped light source generation module of cruciform coordinate light beam, such as being the infrared laser generator, in the specific implementation, also can adopt other light sources without lasing light emitter.Image capture module can be Charge Coupled Device (CCD) imageing sensor (Charge Coupled Device, hereinafter to be referred as: CCD) camera, be arranged on the oblique upper of belt, such as, the optical axis of CCD camera and the angle of belt can be set to 45 degree, this CCD camera can adopt the area array CCD or the line array CCD of 320 * 240 common pixels, and it comprises convex lens and CCD capacitive coupling device.During work, the CCD camera carries out Image Acquisition with certain frequency, and outputting video signal.Data processing module can be computing machine.The concrete principle of work of this belt deviation monitoring device is as follows, and the infrared laser generator is got the coordinate light beam, can projection form the cruciform coordinate on the horizontal tangent plane of belt when this cruciform light beam is beaten on belt.Fig. 2 is the principle schematic of the utility model belt deviation monitoring device embodiment, as shown in Figure 2, the drop shadow spread of this cruciform coordinate covers the width range of belt 4, and in the present embodiment, two edge lines are parallel and be positioned at the centre of these two edge lines about wherein light beam of this cruciform light beam and belt 4, two edge line square crossings of another light beam and belt 4, like this two of belt 4 edge lines with its that light that intersects on formed two coordinates, promptly the length of these two edge lines distances that light in parallel is respectively a and b.The image that cruciform coordinate light beam shown in Fig. 2 forms on belt 4 is caught by the CCD camera, and the CCD camera becomes digital data transmission to arrive connected data processing module the image transitions that photographs, data processing module can be computing machine or single-chip microcomputer, for example (Field-Programmable Gate Array is called for short: FPGA) integrated chip field programmable gate array.Present embodiment is example with the computing machine, comprises image pick-up card and processing unit in this computing machine, and processing unit is connected with the CCD camera by image pick-up card, obtains CCD camera image transmitted.Computer real-time is handled every width of cloth image, it knows the coordinate when belt 4 normally moves in the CCD camera in advance, before actual measurement, need to demarcate the coordinate parameters in this coordinate light beam image, under the situation that does not have material on the belt, take the position of cross-shaped cursor, earlier as normal place, when being set in the normal operation of belt 4, a and b equate; When material is arranged, the coordinate pixel of every width of cloth image of real-time statistic analysis CCD camera transmission, analyze the variation of the cruciform coordinate length in pixels that projection forms on belt 4 horizontal tangent plane directions, the left and right edges line that is belt 4 is respectively apart from the length in pixels a and the b of that parallel with these two edge lines in cruciform coordinate light beam light, when a and b are unequal, then can judge this belt 4 sideslip, and the processing unit of computing machine also will be analyzed and thereby concrete intensity of variation and the difference of comparative belt 4 coordinate length in pixels a and b draw the accurate data of belt 4 sideslips, utilize follow-up accurate correction thereby more have.
The utility model belt deviation monitoring device is judged the sideslip degree of belt by the coordinate light beam that adopts laser generator, simple in structure, the precision height, and belong to contactless direct measurement, reliability and stability are good, be applicable to various conveyer belts, make the utility model belt deviation monitoring device that wide application prospect be arranged.
It should be noted that at last: above embodiment is only in order to explanation the technical solution of the utility model but not limit it, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solutions of the utility model.
