The specific embodiment
The specific embodiment of the invention provides a kind of slipping of the belt checking system, as shown in Figure 2, comprise at least one roller 201, this roller 201 is driven by belt, its at least one side is provided with mark, and this mark position departs from described roller center, image collecting device 203, be arranged at roller 201 side outer rims, for obtaining the starting point moment of Preset Time and the graphicinformation of terminal roller 201 at least one side constantly; And belt skidding detecting device, this device comprises receptor 205, for receiving the starting point moment of described Preset Time and the graphicinformation of terminal roller 201 at least one side constantly; With controller 207, for identifying the mark of described graphicinformation, constantly and the terminal position in the graphicinformation of at least one side of described roller constantly, and according to the described starting point that is marked at described Preset Time, whether the position constantly and in the graphicinformation of the terminal moment at least one side of described roller is identical judges whether to occur slipping of the belt for the starting point that is marked at described Preset Time described in calculating respectively.
This slipping of the belt checking system, can also comprise prior-warning device 209, for reporting to the police in the situation that determining slipping of the belt and/or stopping belt operation.
The roller that should be driven by belt, can, for one or more, can be flower wheel or tension wheel, but can not be driving wheel.Because the rotation of driving wheel is generally by driven by motor, and flower wheel or tension wheel are to rely on driving wheel to drive belt by belt, to drive its rotation more afterwards.When there is slipping of the belt, the flower wheel or the tension wheel that rely on belt to drive just turn motionless, thereby can determine whether belt skids by judging whether the roller that be driven by belt rotates.
On roller one side being driven by belt, set a mark, this mark can adopt the modes such as picture, welding to realize, but does not limit to these implementations.Mark can be special symbol, special color or is the two combination, but not only for described content.As shown in Figure 3, triangle table is shown mark, and roller center is generally departed from its position.Marked region is preferably unsuitable excessive, general 1/4 of the roller side overall region that do not surpass.
Image collecting device can be camera Real-time Collection video, also can periodically take pictures for photographic camera, but be not limited to aforesaid way.Image collecting device is installed in mark markd roller side outer rim, takes direction and aims at this roller side.
When controller receives the starting point moment of Preset Time and the graphicinformation of terminal roller side constantly that image collecting device obtains, need the graphicinformation to collecting to analyze and identify distinctive mark, thereby draw the location information of distinctive mark in graphicinformation.
In art of image analysis, the mark that pair roller side increases is known method for distinguishing to be had a lot, simply introduce below several, but not only for following method:
1., if the color distortion of the color of mark and roller side is larger, can adopt coloured image separation method.So-called color image split plot design, is divided into different region by technology such as classification or clusters by image to the rgb value of all pixels in image, thereby marked region can be identified;
2., if the color distortion of the color of mark and roller side is little, can adopt edge detection method.So-called edge detection method, by associated picture algorithm, as the edge detection algorithm based on Sobel operator etc., determines the boundary curve of each component part in image, and mark also can identify according to boundary curve naturally.
3. also can not consider color element, set up the images match template of mark in video image, adopt template matching method.So-called template matching method, sets up the template pixel of mark, as the RGB color value template of 10*10, then by the 10*10 template of foundation mobile coupling progressively on image, when the distinctive mark that the match is successful in can recognition image.
After mark in identifying image, can calculate the location of pixels of mark center point (or other R points of mark) in image.If N continuous time mark recognition failures (N is default integer, reducible be decided to be 3), illustrates image collecting device fault, can alarm user process.
Due in the situation that belt does not skid and the integral multiple of roller swing circle, the position of mark can not change, preset time t is arranged to be not equal to the situation of roller swing circle integral multiple, when position in being marked at graphicinformation is identical, (when mark does not have occurrence positions to change) can judge slipping of the belt.Understandably, also can preset time t be set to the integral multiple of roller swing circle T, when position in being marked at graphicinformation is different, (when mark occurrence positions changes) can judge slipping of the belt.
In view of preset time t is set to the situation of the integral multiple of roller swing circle T, detect the judgement cycle longer comparatively speaking, sometimes be unfavorable for the requirement detecting in time, the embodiment of the present invention adopts the situation of preset time t being arranged to be not equal to roller swing circle integral multiple, if the location information of marking is P1=(X1 during Preset Time starting point, Y1), during Preset Time terminal, the location information of marking is P2=(X2, Y2), judge that P1 and P2 are whether on same position, can adopt following method, but be not limited to following method:
1. directly calculate the distance of P1 and P2
Figure BDA0000383781440000061
if the distance theta < δ of P1 and P2, illustrate roller do not rotate or rotate not obvious, thereby can judge slipping of the belt.Wherein, the threshold value of δ for setting, determining of this value is relevant to preset time t.For example, in t=0.5*T situation, δ can be set as mark to the distance at roller center.
2. calculate P1 and P2 abscissa difference: Δ X=|X2-X1|, P1 and P2 ordinate difference: Δ Y=|Y2-Y1|, if Δ X< δ X or Δ Y< δ Y, illustrate roller do not rotate or rotate not obvious, thereby can judge slipping of the belt.Wherein, δ X, the δ Y threshold value for setting, both can get identical value, also can be different.The twice of the desirable mark maximum radius of δ X, δ Y (center is to the ultimate range at edge).
