Economic loss.
The content of the invention
The purpose of the present invention is to overcome the problems of prior art, there is provided a kind of video by being shot to video camera
The area that analysis draws material on belt is carried out, the thickness of material on belt is drawn by laser range finder, passes through belt speed measuring
Instrument measures the speed of service of belt, so as to calculate the inspection of the belt conveyor flow of the instantaneous and accumulation amount of material on belt
Survey device and detection method.
The technical scheme is that：A kind of belt conveyor flow detector, including belt conveyor, Belt Conveying
Electrical-mechanical control device, it is characterised in that the tachymeter of the measurement belt speed of service is provided with belt conveyor, in belt
Video camera and laser range finder are installed above the belt of conveyer, detection signal is conveyed to meter by video camera and laser range finder
Calculation machine, computer are connected with belt conveyor electrical control gear；Above-mentioned video camera includes fixed mount and on video camera
Light compensating lamp composition, above-mentioned light compensating lamp is white light or/and infrared lamp.
The mode of movement that detection signal is conveyed to computer by above-mentioned video camera and laser range finder is by optical cable or nothing
Line emitter is conveyed.
The method that flow detection is carried out using belt conveyor flow detector, the detecting step of this method：
A:Utilize video camera（1）Belt in the belt conveyor of setting regions is shot, while utilizes laser range finder
（4）Material thickness H on belt in belt conveyor is detected；
B:Using computer to video camera（1）Shooting video is converted into time interval identical Single frame digital figure in chronological order
Picture；
C:Calculate the material area S on belt in every frame of digital image；
D:Belt conveyor flow=K × S × H × V
Wherein：K --- check coefficient, K=0.1-0.8；S --- material area on belt；H --- material thickness on belt；
V --- the belt speed of service；
E:By the flow of belt conveyor and the setting of time, the speed of service of belt in belt conveyor is controlled.
The above-mentioned material area S calculated in every frame of digital image on belt is to use the belt of shooting area being divided into
The form of 100 grids is calculated.
The technical scheme is that using video camera and laser range finder is installed above the belt of belt conveyor, lead to
Cross the image that computer is shot to video camera and carry out real-time image analysis, draw material occupied area on belt, while by swashing
Optar draws the thickness of material on belt, so that it may the instantaneous delivery of belt conveyor is calculated, with reference to measurement belt operation
The tachymeter of speed can measure the belt conveyor flow in setting time；When flow is less than setting value, pass through calculating
Machine sends instruction to belt conveyor electrical control gear, reduces the speed of service of belt conveyor；Set when flow reaches minimum
During definite value, instruction is sent to belt conveyor electrical control gear by computer, stops the operation of belt conveyor, can reach
The purpose of using electricity wisely.
Technical scheme has simple in construction, easy for installation, the amount of material on belt conveyor can be carried out real
When monitor, can effectively improve underground conveyer belt operation safe and reliable property, while can according to flow setting value, belt
The speed of service of conveyer automatically adjusts.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present invention；
Accompanying drawing 2 is the structural representation of video camera of the present invention；
Accompanying drawing 3 is the left view of accompanying drawing 2 of the present invention.
Embodiment
As shown in Figure 1, 2, 3, video camera 1, laser range finder 4 are installed above the belt of belt conveyor 5, it is defeated in belt
The tachymeter that the measurement belt speed of service is provided with machine is sent, video camera, laser range finder and tachymeter convey detection signal
To computer 2, computer is connected with belt conveyor electrical control gear 3.
A:The belt in the belt conveyor of setting regions is shot using video camera, while utilizes laser range finder
Material thickness H on belt in belt conveyor is detected；
B:Time interval identical Single frame digital image is converted into chronological order to video camera shooting video using computer；
C:Calculate the material area S on belt in every frame of digital image；Material area is to use image processing software, will be shot
The belt in region is divided into 100 grids, and the form for accounting for belt percentage in shooting area by material is calculated；Such as
Material accounts for belt area 89%, area S=0.89 in shooting area.
D:Belt conveyor flow=K × S × H × V；
Wherein：K --- check coefficient, K=0.1-0.8；S --- material area on belt, square measure are square metre M2；
H --- material thickness on belt, thickness unit are rice M；V --- belt speed of service rice M/S per second.
COEFFICIENT K is checked according to selecting between 0.1-0.8 after carrying out manual measurement to belt conveyor flow, with raising
The accuracy of flow monitoring.
, will by the fixed mount 1-1 on camera body 1-3 such as the coal conveying belt conveyor of coal mining activity
Video camera is arranged on above the belt of belt conveyor, while using the light compensating lamp being arranged on video camera to camera photography head
1-4 shooting areas carry out light filling, and light compensating lamp use white light 1-2 or infrared lamp 1-5, and best mode is to use white light and red
Outer smooth lamp carries out the mode of light filling, or the side using white light and the common light filling of ultraviolet lamp to video camera shooting area simultaneously
Formula, by largely testing, a length of 770nm to the 1000nm of infrared wave, the ultraviolet wavelength of ultraviolet lamp is 400-190nm's
Light, in the image after being shot by video camera, the accurate face for determining coal on belt clearly, is easy in the edge of coal and belt
Product.
By setting of the computer to flow, when the area of the coal on belt is less than setting value, by computer to skin
Band conveyer electrical control gear sends instruction, reduction belt conveyor running speed, as the coal on belt area 40-
When changing between 60%, and maintaining 5 minutes, the speed of service of belt conveyor drops to 6M/S by 10M/S, when the coal on belt
Area change between 10-40%, and when maintaining 5 minutes, the speed of service of belt conveyor drops to 4M/S by 6M/S, when
The area of coal on belt is less than 10%, and when maintaining 5 minutes, the belt conveyor tear or coal bunker that illustrate upstream are blocked
