The device comprises a glass conveyer belt, wherein two monitors are arranged above the glass conveyer belt; the monitors are electrically connected with an image supervisor and a video acquisition card respectively through cables; the video acquisition card is electrically connected with a computer processing system; and the monitors are industrial monitoring lenses which are arranged on two sides above the glass conveyer belt respectively. Compared with the prior art, the device and the method have the beneficial effects that: the width and the position of a glass plate can be detected in real time and accurately; a real-time pull quantity can be calculated according to information, such as the width, the speed and the like, of the glass plate, and precise control over float production is facilitated; and meanwhile, the device and the method have the advantages of high measurement speed, zero mechanical abrasion, high anti-interference capacity and the like.
Description
Technical field
The invention belongs to float glass manufacturing technology field, be specifically related to the wide real-time detection method of the online plate of a kind of float glass.
Background technology
At present, the measurement that the floatation glass production line glass plate is wide, major part goes out the laggard pedestrian worker of annealing kiln at glass to be measured, and so not only can increase manpower, and can cause measurement data can not in time objectively respond the virtual condition of glass plate; Importantly because annealing kiln is longer, glass approximately needs 30 minutes time by annealing kiln, so adopt this mode to have bigger retardation time, can not in time reflect parameters such as width of glass sheet and drawing amount, bring unfavorable factor for the steady production of glass.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, the wide real-time detection apparatus of the online plate of a kind of float glass and detection method are provided, it can detect the width of float glass plate in real time, exactly.
The technical solution adopted for the present invention to solve the technical problems is: comprise the wide real-time detection apparatus of the online plate of float glass, described real-time detection apparatus is provided with monitor above the glass conveying belt; Described monitor is more than one industrial monitoring camera lens, is arranged at the both sides, top of described glass conveying belt respectively, and described monitor electrically connects picture monitor, video frequency collection card respectively by cable; Described video frequency collection card electrically connects computer processing system; It is characterized in that: it is as follows to detect step:
1) starts the computer processing system program, the digital picture that the vision signal from the industrial monitoring camera lens that extraction is handled by video frequency collection card converts to;
2) input rectangular area and ratio arm extract digital picture;
3) point by point scanning is carried out in the rectangular area that can arrive glass edge, adds up by the glass edge direction then;
4) Numerical Value Derivative to adding up is again found out catastrophe point, real-time width and the positional information of trying to achieve glass plate by x or the y coordinate of catastrophe point;
5) according to glass plate speed and thickness information, calculate glass drawing amount in real time, plate is wide and center offset;
6) information such as output width of glass sheet and position, EOP (end of program).
Compared with prior art, the invention has the beneficial effects as follows: can detect width of glass sheet and position in real time, exactly, according to the real-time drawing amount of information calculations such as width of glass sheet, speed, be convenient to realize the accurate control that float glass process is produced, also have measurement simultaneously and rapidly, do not have advantages such as mechanical wear and antijamming capability are strong.

Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described further:
As shown in Figure 1, 2, the wide real-time detection apparatus of the online plate of float glass comprises glass conveying belt 1, above the both sides of edges of described glass conveying belt 1, an industrial monitoring camera lens 2 respectively is set, and the imaging scope of industrial monitoring camera lens 2 contains the zone that glass plate edge arrives; Described industrial monitoring camera lens 2 electrically connects picture monitor 3, video frequency collection card 4 respectively by cable; Described video frequency collection card electrically connects computer processing system 5.
Principle of work of the present invention and the course of work are as follows:
As shown in Figure 1, 2, industrial monitoring camera lens 2 can be arranged in the floatation glass production line molten tin bath, tin bath outlet, annealing kiln and annealing kiln outlet, preferred scheme is to be positioned at the top that tin bath outlet opens wide district's glass conveying belt 1, and the limit portion moving area scope of glass conveying belt 1 is positioned within the imaging scope of industrial monitoring camera lens 2.The vision signal that industrial monitoring camera lens 2 collects is transferred to picture monitor 3 by video transmission cable, is convenient to the Central Control Room operating personnel and observes dangerous situations such as tin bath outlet has or not crimping, the plate that breaks.When being transferred to picture monitor 3, vision signal is passed to video frequency collection card 4, video frequency collection card 4 is the two-path video capture card, it can be converted to digital picture with the vision signal of the industrial monitoring camera lens 2 that collects, be input to computer processing system 5,5 pairs of digital pictures of computer processing system are carried out programmed process, and its programmed logic block diagram is seen as shown in Figure 2.
Use said apparatus to the wide method that detects in real time of the online plate of float glass, comprise the steps: 1) start computer processing system 5 programs, extract by video frequency collection card 4 handle from the digital picture that converts to of the vision signal of industrial monitoring camera lens 2; 2) input rectangular area and ratio arm extract digital picture; 3) point by point scanning is carried out in the rectangular area that can arrive glass edge, adds up by the glass edge direction then; 4) Numerical Value Derivative to adding up is again found out catastrophe point, real-time width and the positional information of trying to achieve glass plate by x or the y coordinate of catastrophe point; 5) according to glass plate speed and thickness information, calculate glass drawing amount in real time, plate is wide and center offset; 6) information such as output width of glass sheet and position, EOP (end of program).
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
