Door carries out the main tool of many scientific researches.Owing to it has powerful calculating and drawing function, the most reliable and the most stable calculation
Faku County and be concisely and efficiently programming language, it has also become mathematical computation tool aspect de facto standards.By data acquisition and
Both MATLAB platform softwares organically combine and will bring great convenience to actual application.
Summary of the invention
It is an object of the invention to, for existing cable shielding line material in problem present on resolution, the present invention provides one
Plant cable screening wire material resolution system based on MATLAB.
The technical scheme is that a kind of cable screening wire material resolution system based on MATLAB, including portable
Stereomicroscope, notebook computer, the data module of MATLAB and data analysis module.
The shielding line sample of polishing, for being acquired the data of shielding line, is placed on by described portable stereomicroscope
On the object stage of the portable stereomicroscope being already connected on notebook computer, the software of computer automatically derives shielding
The edge contour image clearly of line, then imports the image obtained in MATLAB and processes.
The data module of described MATLAB, is for storing the data base of shielding line sample and saving as file so that at any time
Call for MATLAB software；Data module includes three groups, is fine copper, pyrite, copper cover aluminum respectively, module file big
Little is often to organize 30 shielding line images, all comes in the shielding line at distribution box of transformer substation scene.
Described matlab data analysis module, obtains rectangular histogram produced by unlike material shielding line for computational analysis bent
Line.And from DBM, read data data are analyzed, and carry out histogrammic feature and mate, and
The result of whole output matching.
Described notebook computer, on the one hand connects portable stereomicroscope；On the other hand be provided with MATLAB software and
Self-editing grade enough reflects the software of shielding line kind, the result finally the mated type of the material of shielding line is intuitively reflected
On computer screen.
The invention has the beneficial effects as follows, the present invention is that a kind of hardware resource utilizing notebook computer itself and MATLAB put down
The shielding line material data of platform software, portable stereomicroscope exploitation gathers and the system of analysis, its simple in construction, equipment amount
Little, motility is high, and cost is low.The present invention is not required to loaded down with trivial details manual operation process, software automatically run.Therefore, operator

Detailed description of the invention
As it is shown in figure 1, the step of present invention shielding line based on MATLAB material resolving method is as follows:
(1) the shielding line sample of polishing is placed on the object stage of portable stereomicroscope, by portable stereomicroscope even
Connect notebook computer；The data of shielding line are acquired by portable stereomicroscope；
(2) image obtained is imported notebook computer, MATLAB software process；
(3) shielding line image is carried out feature extraction；
(4) data module computational analysis obtains histogram curve produced by unlike material shielding line；
(5) from DBM, read data and data are analyzed, and histogrammic feature is carried out matching characteristic
Coupling；
(6) output result.
Fig. 2～Fig. 4 is the image in the present embodiment implementation process.
Fig. 2 show portable stereomicroscope for being acquired the data of shielding line, and concrete mode is for will polishing
Shielding line sample be placed on the object stage of the portable stereomicroscope being already connected on notebook computer, collect shielding line
The gray-scale map of the shielding line arrived after processing in MATLAB after the information of material.
Shown in Fig. 3, after obtaining the gray-scale map of shielding line, the gray-scale map obtained is processed in MATLAB automatically,
To shielding line edge contour image clearly.
Shown in Fig. 4, by matlab data analysis module and data module, obtain unlike material shielding for computational analysis
Histogram curve produced by line.And read data from data module and be analyzed data, and it is bent to carry out rectangular histogram
The feature of line is mated, and the result of final output matching is consistent with the histogram curve of copper cover aluminum.
On the self-editing software that can reflect shielding line kind of notebook computer, the result finally mated is used intuitively
The type of the material of shielding line is reflected on computer screen.Last result is copper-clad aluminum conductor.
According to procedure above, tell other two kind shielding line kind: pyrite and fine copper.Repeat to each distribution box
Shielding line material be resolved out.Fine copper is qualified, and additionally copper cover aluminum and pyrite are defective.
