Description
Technical field
The present invention relates to a kind of processing and manufacturing field related to fluid media (medium), in especially a kind of convection body industrial production
Fluid media (medium) in pipeline carries out automatic identification control device and identification control method.
Background technology
Application of the Visual identification technology in modern industrial production is more and more extensive, such as industrial automatic control, office certainly
The industries such as dynamicization, material sorting identification, image procossing, product quality, robotic vision system are required for carrying out image/color
Detection.The color measuring instrument that its equipment is broadly divided into the optical signal e measurement technology based on object reflection, transmission and/or refraction is set
The standby and photo electric imaging system equipment based on machine vision technique.
Conventional color measuring instrumentss mainly have：Color sensor, gray-scale sensor, color mark sensor, Chromatic sensor, instrument
The table way of output is generally analog output, output switch parameter, communication output, needs to select according to measurement type selecting.
Color sensor：It is a kind of sensing device, is to carry out object color with the reference color of above teaching
Compare to detect the device of color.When two colors match in certain error range, testing result is exported.
Gray-scale sensor：It is a kind of analog sensor.Gray-scale sensor utilizes reflection of the detection faces of different colours to light
Degree is different, light its resistance that photo resistance returns to different detection faces also different principle progress shade detection.In ring
Light interference in border is not very under serious situation, for distinguishing black and other colors.
Color mark sensor：Various labels are detected, even the color that background color has fine distinction also may be used
To detect, processing speed is fast.It is automatic to adapt to wavelength, the small differences of gray value, the mixing with label and background can be detected
Color is unrelated.
Chromatic sensor：The color of testee and the aberration of Standard Colors are detected, not it should be understood that the tool of measured object
Body color, and only need that the aberration of two objects is identified and judged, distinguish from one color to another color
Change.
Machine vision technique is a kind of young, new industry technology, is used instead the visual performance of human eye at present, its
System architecture is by photoelectric imaging device and is provided with the microcomputer of vision software and forms, and mainly has three kinds of forms, i.e., industrial camera,
Smart camera, vision sensor, its machine body have communication function, have and the solid matter of definite shape and volume is carried out
Automatic sizing, inspection, guiding, identification.
Industrial camera includes camera, camera lens, light source and light source controller, and the device does not have image process and analysis work(
Can, it is output to the image of live shooting on the microcomputer equipped with vision software, is carried out image procossing to image by microcomputer and is divided
Analysis；Smart camera and vision sensor are embedded systems, are the special-purpose computers designed for image process and analysis application
System, the machine have image process and analysis function.Smart camera image process and analysis ability is higher, for high requirement
Application scenario；Vision sensor collection IMAQ, light source, camera lens, image procossing are controlled in one, are such as used for with/without detection
Etc. the simple occasion of application requirement.
Machine vision technique is based on Modern Optics Technology, fusion calculation machine technology, image processing and analysis technology, from
The modern science and technology such as dynamic control technology are integrated, and have precision high, monitor the spies such as analysis in real time, control and continuous work on-line
Point, semiconductor, electronic component, household electrical appliance, automobile, lathe and automation equipment etc. are successfully applied to, and in numerous stream
In body industrial production, also all still continue to use traditional artificial visor observation, i.e., in the place that needs are examined, pipe laying visor,
By manually by the external appearance characteristic of visor field observation fluids within pipes, such as：Color, different colours two kinds of fluid interface faces,
Foreign matter for being different from fluid color etc. is whether there is in fluid, according to manufacturing technique requirent, by the phase for manually making manufacturing technique requirent
It should operate.
For example, in Beer Brewage, the wheat juice of saccharification workshop section production is with being pumped into the fermentation tank of fermentation workshop section, root
According to technological requirement, wheat juice first has to sterilize wheat juice conveyance conduit with hot water, wheat juice during fermentation tank is pumped into from saccharification
Followed by conveyed, i.e., usually said draws wine；Mashing operation personnel use water at the end of the wheat juice of the batch enters tank
From saccharification pump to the wheat juice fermentation workshop section fermentation tank in pipeline, with water whole jacking fermentation tank, i.e., after wheat juice has conveyed,
And then water, i.e., usually said top wine are conveyed.The purpose is to which wheat juice is all sent into fermentation tanks, and draw wine, top wine uses water
Fermentation tank can not be entered, otherwise will increase cost consumption, or influence product quality.
Identification of the operating mode to water and wheat juice, Main Basiss color distortion are identified.Because water is colourless, wheat juice is
It is auburn, fermentation operation personnel, when wheat juice enters tank practical operation, need field observation to be arranged on fermentation tank cone bottom pipeline
Visor, when two kinds of fluid media (medium)s for occurring continuously flowing in visor cross interface or color change when, completed by manual operation
Valve transfer, i.e., when see water and wheat juice cross interface or color change when (being above water, be followed by wheat juice), that is, carry out valve
Door switch switches --- wine inlet valve door is opened, drinks recovery valve is drawn in closing, and wine operating process is drawn in completion.Similarly, when the batch
At the end of wheat juice enters tank, fermentation operation personnel observe cross interface or the color change of wheat juice and water by boring bottom pipeline visor
When (being above wheat juice, be followed by water), operating personnel are with regard to handover operation valve --- close wine inlet valve door, open top drinks recovery
Valve, complete top wine operating process.
During fluid colour recognition, two kinds of fluid colors are similar sometimes, or even are difficult to distinguish, such as：Beer Brewage
During the cleaning of middle fermentation tank, the temperature for washing clear water is 60 DEG C, and water-detergent solution is normal-temperature water, and the two is when passing through visor,
Its characteristics of image is substantially the same, now according to the difference of temperature of fluid medium, can clearly give judgement identification；
In wheat juice course of conveying, the temperature of wheat juice is usually 7 DEG C, when ambient temperature is higher than wheat juice temperature, and ring
When border humidity is suitable, visor minute surface can produce condensed water (in some application scenarios, as being less than when the medium temperature in fluid line
At 0 DEG C, the meeting of visor minute surface frosting, even ice), operating personnel can wipe visor mirror with hand in time in order to clearly observe fluid
Face condensed water (frost/ice), visor mirror surface cleaning is kept, ensure observation quality.
Because wheat juice fluids within pipes flow velocity is fast, the interface of two kinds of fluids is not easy to catch in time, is seen before artificial visor mirror
Examine, be limited to the influence of human users' experience, physical fatigue situation, easily cause operating error, not only increase production cost and disappear
Consume, have impact on product quality, and add the labor intensity of operating personnel, while also constrain fluids industry production process certainly
