Object carrier, machine run to conveyor belt surface abrasion etc. reason, it occur frequently that conveyer band discerption failure.For longitudinal tear and small
The fault detect of tearing port, now widely used method has sensor to detect material leakage, surface image collection, internal pre-buried coil
Detected etc. mode, but due to these methods all exist adaptability under detection accuracy, real-time, mal-condition compared with
The problems such as difference, so that one can adapt to accurately detect conveyer belt run time behaviour in real time under mal-condition
Device.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of existing conveyer belt detection scheme and device, and design one kind can be accurate in real time
The detection method and system and device of the conveyer belt situation during really detection is operated.
The general principle of detection method is：Picture is scattering into using X-ray and image processing techniques realizes longitudinal rip event
Barrier detection.
Device of the invention is sentenced by X-ray backscattering scan module, X-ray information detection module, surface image-forming module, failure
Other module composition.X-ray backscattering scan module, X-ray information detection module are located at conveyor belt surface to be detected lower section, X-ray letter
Breath detecting module is connected with surface image-forming module, and surface image-forming module is connected with fault distinguishing module.
Technical scheme：The present invention is method and dress based on X-ray backscattering detection conveyer band discerption failure
Put, vertical tearing is realized to the real time imagery of conveyor belt surface state, using image processing techniques using the realization of X-ray backscattering technology
Fault distinguishing, apparatus structure feature is：By X-ray backscattering scan module, X-ray information detection module, surface image-forming module, event
Barrier discrimination module composition.
X-ray backscattering scan module core component is x-ray source, and x-ray source produces X-ray and in running
Conveyer belt hypodermis band lower surface area is projected.X-ray information detection module by two X-ray backscatter detectors, (i.e. visit by X-ray information
Survey module -1 and X-ray information detection module -2) constitute, X-ray backscatter detector is respectively placed in the both sides of x-ray source, uses
The X-ray information of all directions is scattered in by conveyor belt surface in reception.Surface image-forming module is used to receive X-ray reception mould
X-ray information that block is sent simultaneously generates conveyor belt surface image.Fault distinguishing module is made up of discriminating gear, display, failure
Discrimination module receives the simultaneously conveyor belt surface image of display surface image-forming module generation and surface appearance is differentiated, in display

Mark in Fig. 2 is as follows：
The subregion 1 of conveyer belt to be measured, x-ray source 2, X-ray backscatter detector 3.
Specific embodiment
The specific embodiment of the content of the invention is illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, present system is built including X-ray backscattering scan module, X-ray information detection module, surface
Image-forming module, fault distinguishing module.First, subregion divergent-ray from X-ray backscattering scan module to conveyer belt to be measured,
X-ray by conveyor belt surface scattering, the X-ray information comprising conveyor belt surface state just can be by X-ray information detection mould
Block is received；After X-ray information detection module receive information, by the X-ray information comprising conveyor belt surface state send to surface into
As module, conveyor belt surface image is generated；The conveyor belt surface image that surface image-forming module will be generated is sent to fault distinguishing
After module, comprising discriminating gear receive and display surface image-forming module generation conveyor belt surface image and to surface appearance
Differentiated, the real-time image information and fault distinguishing result shown in the display for being included are available for staff to enter pedestrian
Work real-time monitoring.
As shown in Fig. 2 x-ray source 2 and two X-ray backscatter detectors 3 may be mounted at the conveying in running
Band (being the subregion 1 of conveyer belt to be measured in figure) lower section, two X-ray backscatter detectors 3 are separately mounted to x-ray source 2
Both sides.The divergent-ray of subregion 1 from x-ray source 2 to conveyer belt to be measured, X-ray by conveyor belt surface scattering, X-ray
Information can just be received by X-ray backscatter detector 3, and then carry out the treatment of next step, so that it may detect conveyor belt surface
Whether state is normal.
