Abstract
The invention belongs to the technical field of tubular conveyor belt detection, and relates to a detection method for the state of a tubular conveyor belt. The detection method achieves the technical purpose of providing a method through which the state of the tubular conveyor belt can be detected online in real time. According to the adopted technical scheme, the detection method for the state of the tubular conveyor belt involves cameras, light sources and the tubular belt; the cameras are installed above the cross section of the tubular belt at equal intervals, wherein the distance between the cameras and the cross section of the tubular belt is L; and the light sources are installed at the positions L away from the cameras in the direction the same as the length direction of the tubular belt. The method includes the following steps that the image, projected by the light sources on the tubular belt, shot by the cameras corresponding to normal running of the tubular belt is established as the reference value S. When the image changes, the difference value delta S between the peak value S1 and the reference value S is measured, when the delta S is larger than 0, it is confirmed that tube expansion happens to the tubular belt, and when the delta S is smaller than 0, it is confirmed that tube collapse happens to the tubular belt, and the tube collapse value is the delta S. By means of the detection method, the visual display of the height change amount of the section of the round tubular belt is achieved, operation of an algorithm is omitted, the personal error is effectively reduced, and efficiency is improved.
Description
Technical field
The present invention relates to tubular conveyor belt detection technique, be specifically related to the detection method of a kind of tubular conveyor belt state.
Background technology
Pipe conveyer is a kind of conveyer new architecture for material transferring, its conveyer belt originally is plane, at charging, the both sides of plane conveyer belt gradually upsweep, and make plane conveyer belt gradually become grooved conveyer belt, after its dual-side coincides together, plane conveyer belt has been rolled into tubular conveyor belt, transporting in material is rolled in airtight pipe, when close to discharge pit, tubular conveyor belt is re-opened into plane.
In recent years, pipe conveyer due to course of conveying have seal, conveying circuit strong adaptability, conveying material variety extensively, conveying materials in double directions and the advantage such as frame width is little can be realized, already start to popularize in large number of rows;But circular pipe belt type conveyer is in transportation, the reasons such as the impact (unilateral frictional force can be made on belt to reduce as raindrop rack to beat) of difference and environment owing to loading material, likely result in circular pipe belt type conveyer and torsion, anti-package, tube, the faults such as pipe of collapsing occur, thus tubular conveyor belt cannot normally be opened when causing discharging, the generation caused the accident.
And the fault using the mode of hand inspection to avoid tubular conveyor belt to cause, when staff finds that tubular conveyor belt has abnormal, shut down in time, correct. the most more;This method both wasting manpower and material resources, make again inefficiency, just in case staff finds fault the most in time, it will bring immeasurable economic loss to business unit.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, technical problem to be solved to be: provide a kind of can the method for real-time online detection tubular conveyor belt state.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is as follows: the detection method of a kind of tubular conveyor belt state, including camera, light source and pipe racks, it is that between L and camera, spacing is identical that described camera is arranged on distance on the cross section of pipe racks, described light source is arranged at distance camera L, identical with pipe racks length direction, said method comprising the steps of: set up corresponding to described pipe racks time properly functioning camera shooting pipe racks on light sources project image on the basis of value S.When image changes, measuring peak value S1, and difference DELTA S of reference value S, when Δ S > 0 determines that pipe racks tube expansion, tube expansion value are Δ S, when Δ S < 0 determines that pipe racks collapses pipe, and pipe value of collapsing is Δ S.
The changing value Δ S of described pipe racks is less than camera heights value L.The visual angle of described camera reaches 180 degree.Described light source is the brightness unblanketed point source of adjustable flicker free, and light and pipe racks length direction are 45 degree.Described tubular conveyor belt is at least provided with 3 groups of cameras and light source.
The present invention compared with prior art has the advantages that
The present invention utilizes many group cameras to take pictures, and grasps the situation of change of belt moment, can detect pipe racks ruuning situation in real time, effectively make breakdown judge, to judging that pipe racks operation troubles is significant in advance.The brightness scalable of point source in the present invention, the light sent equilibrium flicker free shadow-free, thus ensure the definition of image shot by camera.
In the present invention, camera is equal with the distance of pipe racks with the distance of light source and camera, so pipe band depth of section variable quantity is equal to the variable quantity of the image of camera shooting so that pipe band depth of section variable quantity is directly perceived, removes the computing of algorithm from, effectively reduce personal error, and improve efficiency.
Accompanying drawing illustrates:
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail:
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the flow chart of a kind of embodiment of back drill detection method of the present invention;
In figure: 1 is camera, 2 is light source, and 3 is pipe racks.
Detailed description of the invention:
Below in conjunction with accompanying drawing, technical scheme is clearly and completely described.
As shown in Figure 1 and Figure 2, a kind of detection method of tubular conveyor belt state, including camera, light source and pipe racks, it is that between L and camera, spacing is identical that described camera is arranged on distance on the cross section of pipe racks, described light source is arranged at distance camera L, identical with pipe racks length direction, said method comprising the steps of: set up corresponding to described pipe racks time properly functioning camera shooting pipe racks on light sources project image on the basis of value S.When image changes, measuring peak value S1, and difference DELTA S of reference value S, when Δ S > 0 determines that pipe racks tube expansion, tube expansion value are Δ S, when Δ S < 0 determines that pipe racks collapses pipe, and pipe value of collapsing is Δ S.When so pipe racks is properly functioning, ensure that the point that camera, light source and pipe racks are photographed constitutes an isosceles right triangle, when pipe racks occur tube expansion or collapse pipe time, the point of irradiation of camera subpoint on pipe racks, the point that pipe racks is photographed time normal and light source still constitutes an isosceles right triangle, it is directly perceived that such embodiment can realize pipe band depth of section variable quantity, remove the computing of algorithm from, effectively reduce personal error, and improve efficiency.
The changing value Δ S of described pipe racks is less than camera heights value L.The visual angle of described camera reaches 180 degree.Described light source is the brightness unblanketed point source of adjustable flicker free, and light and pipe racks length direction are 45 degree.Described tubular conveyor belt is at least provided with 3 groups of cameras and light source.So ensure that pipe racks shoots without dead angle.The brightness scalable of point source in the present invention, the light sent equilibrium flicker free shadow-free, thus ensure the definition of image shot by camera.
