The present invention relates to a kind of targeted electronic control method, this method includes using targeted electronic control system based on the closeer screening separation equipment progress self adaptive control to coal cinder screening lock out operation is executed of coal cinder distribution density in dump.
Description
Technical field
The present invention relates to field of electric control more particularly to a kind of targeted electronic control methods.
Background technique
Electronic control refers mainly to be vulnerabilities scan forceful electric power, is technology-oriented discipline, general can see concrete condition, common use
In the communication for realizing single-chip microcontroller and computer, computer gives single-chip machine information, chip microcontroller control as main processing equipment
System.
Electric control system is commonly referred to as electrical equipment secondary control loop, and different equipment has different control loops,
And the control mode of high voltage electric equipment and low voltage electrical equipment is not also identical.
Wherein, be controlled electronically and be with the main distinction of electrical control: electrical control range is bigger, and range is controlled electronically
Small, usually electrical control includes electronic control.
Coal mine is the mankind in the region of the mining area exploitation coal resources rich in coal, is generally divided into underground mine and outdoor
Coal mine.When coal seam is remote from earth's surface, it is typically chosen to underground and digs tunnel digging coal, this is underground mine.When coal seam is far from ground
When the distance of table is close, it is typically chosen directly removing surface soil layer and excavates coal, this is open coal mine.
Coal mine range includes the very big region of above and below ground and related facility.Coal mine is the mankind in digging rich in there is coal
Geological stratification when the proportional space that is excavated, generally include tunnel, well cave and face etc..Coal is most important solid combustion
Material, is one kind of kaustobilite.It is the plant in great numbers grown by certain geological epoch, in suitable geological environment,
It is gradually accumulated into thick-layer, and is buried in water-bed or silt, is formed by very long geochronic geochronic natural incoalation.?
It is most with producing coal in the stratum in the Carboniferous Period, the Permian Period, Jurassic Period and the Tertiary Period in the world in Various Geolcgical Ages, it is important into
The coal epoch.The phosphorus content of coal is generally 46~97%, brown to black, has dim to metallic luster.According to degree of coalification
Difference, coal can be divided into peat, four class of lignite, bituminous coal and anthracite.
In the prior art, the dump formed in face of that will screen the coal cinder of separation, executes the screening point of screening lock out operation
From equipment, its control model is fixed, the setting of the artificial experience that places one's entire reliance upon progress work in every parameter, for example, coming to it
The setting for returning oscillation amplitude leads to the adaptive low SI for screening separation equipment.

The adjustment of Mobile state range does not execute dynamic range adjustment to other channel value images, to reduce the number of dynamic range adjustment processing
According to amount.
According to an aspect of the present invention, a kind of targeted electronic control method is provided, this method includes using targeted electronic control
System processed based on the closeer screening separation equipment to execution coal cinder screening lock out operation of coal cinder distribution density in dump to be carried out certainly
Suitable solution, the targeted electronic control system include: coal cinder detection device, are connect with equalization processing equipment, for being based on
Coal cinder imaging features identify each coal cinder target from histogram treatment image, based on the coal in the histogram treatment image
The quantity of block target determines corresponding coal cinder distribution density；Separation equipment is screened, is connect with the coal cinder detection device, base is used for
The oscillation back and forth that the screening separation equipment is used when executing and screening lock out operation is determined in the coal cinder distribution density received
Amplitude；Video equipment is monitored, setting is in colliery scene, corresponding to obtain and export for carrying out operation of making video recording in face of dump
Monitor image of making video recording；Noise monitoring device is connect with the monitoring video equipment, is made video recording image for receiving the monitoring, right
The various types noise monitored in image of making video recording is identified；Amplitude analysis equipment is connect with the noise monitoring device,
For the average value of each maximum amplitude for monitoring the various types noise in image of making video recording is defeated as representative amplitude
Out；AVR32 controls chip, connect respectively with the amplitude analysis equipment and the wavelet filtering equipment, for receiving the generation
Table amplitude, and when the representative amplitude transfinites, start the wavelet filtering equipment；The AVR32 control chip is also used
In when the representative amplitude does not transfinite, the wavelet filtering equipment is closed.
Targeted electronic design of control method of the invention is exquisite, facilitates application.Due in view of coal cinder distribution density in dump
Closeer, coal cinder particle is smaller, and the smaller characteristic of the oscillation amplitude back and forth that screening separation equipment needs separates to execute coal cinder screening
Operation, so that the self adaptive control for improving screening separation equipment is horizontal.
