Description
Technical field
The invention belongs to tea processing field, are related to selenium-enriched tea leaf manage bar intensive processing control integrated system.
Background technique
Green tea is the most important consumption teas in current China, and extremely important status is occupied in tea making industry.Usually and
Speech, the production process of green tea has following steps: fresh leaf, which (is not fermented) ,-booth is green-finish-rubs-first baking-manage bar-
At tea.One of critical process during wherein reason bar technique is just made as green tea, tea carding remove moulding (such as bar shaped, aciculiform
Deng) except, also directly affect the qualities such as its color, fragrance, taste.
It had both been had a strong effect during manage bar, and had also played the role of heat.When manage bar, slot pot will be put into through the tealeaves to manage bar
In, motor drive transmission mechanism drives slot pot reciprocating by connecting rod, past in the slot pot of specific temperature to manage bar tealeaves
It is multiple to hit, and constantly roll under the action of slot pot bottom fin, to manage tight bar rope, moisture content is distributed, completes tealeaves moulder
Sequence, the superiority and inferiority of manage bar effect directly influence the formation of the shape and its quality of green tea manage bar.Currently, common tea carding machine
Tool is mostly vibration carding machine, and vibration carding machine has smooth running, structure simple, easily operated, excellent convenient for pipelining etc.
Point.Both tight, thin, straight shape has been moulded in the reliable friction of vibration back and forth to vibration carding machine, and in turn avoiding excessively rubbing becomes color
Secretly；Both tea leaf quality had been developed by heat chemistry effect, and had in turn avoided heat chemistry under high humidity environment and act on to chlorophyll considerable damage.

Timing ring professor seminar is based on the tea carding machine control of ARMCortex-M3 core microprocessor and Double Fuzzy algorithm research
System, they propose the tea carding machine Control System Design scheme based on embedded technology and fuzzy control technology, use
Tealeaves humidity level, kind throw leaf amount as input, are joined by the best reason bar technique that fuzzy algorithmic approach decision obtains current tealeaves
Number；The control precision of carding machine pot bath temperature degree is improved, by fuzzy temperature control algorithm to reduce temperature fluctuation；And according to
Temperature deviation changes pot slot vibration frequency in right amount.
For the tea carding machine that current selenium-enriched tea leaf manufacturing enterprise uses, generally existing temperature control precision is high,
Fluctuation is big, and excessively relies on artificial experience, can not use optimal processing parameter manage bar tealeaves according to different situations, easily cause

Timing belt pulley 36, lifting stepper motor 37, spur rack 38, lower stroke switch 39, upper stroke switch 40, temperature sensor 41,
Slot pot 42, magnechuck 43.Big belt pulley 27, lateral driving motor 28 constitute slot pot transverse movement transmission mechanism with connecting rod 29,
Drive the transverse movement of slot pot；Timing belt pulley 36, lifting stepper motor 37, spur rack 38, lower stroke switch 39, upper stroke switch
40 constitute slot pot lifting control mechanism together, magnechuck 43 are equipped at the top of spur rack 38, magnechuck is in magnechuck
Under the control of control circuit, the control of slot pot inclined lift is realized, lower stroke switch 39, upper stroke switch 40 determine the highest of lifting
Point and minimum point；Temperature sensor 41, humidity sensor 33 are for realizing slot pot temperature and to manage bar tealeaves humidity detection；Figure
As sensor 34 is for realizing to manage bar tealeaves real time image data acquisition；When light filling Led 35 takes pictures for imaging sensor pair
The illuminating ray of photographed scene compensates；Heat power supply device 30 is in the case where PWM controls IP kernel 21 and temperature-control circuit 22 is acted on according to reason
Item is arranged temperature parameter and carries out accurate temperature control；
The magnechuck control circuit by magnechuck 43, solid-state relay I 44-1, solid-state relay II 44-2,
220V turns low-tension transformer 45, A.C. contactor KM246, A.C. contactor KM147, under-voltage relay KMD 48, rectifier bridge 49
Deng composition.It is formed from the figure 3, it may be seen that rectification circuit turns low-tension transformer 45 by rectifier bridge 49,220V, exports DC power supply.Slot pot
During ramping up, magnechuck does not work, only as support pallet effect；During decline, electromagnetism is inhaled first
Disk magnetizes, when magnetizing, by 13 control flume pot lifting motor of the NIOS II soft-core processor control output control signal of IP kernel 11
Con_Ma (high level), Con_Dema (low level), A.C. contactor KM246 main contacts disconnect, the main touching of A.C. contactor KM147
Point closure, magnechuck 43YH coil obtains electric, and slot pot bottom is sucked in sucker；After slot pot falls back to horizontal position, electromagnetism at this time
Sucker should go magnetic treatment, to ensure that slot pot can lateral proper motion.In degaussing, to prevent from making slot pot bottom because of overlong time
Magnetic reversal, by 13 control flume pot lifting motor of the NIOS II soft-core processor control output control of IP kernel 11 signal Con_Ma
(negative pulse), Con_Dema (positive pulse), and control signal Con_Ma and should be complementary waveform with Con_Dema, exchange connects at this time
Tentaculum KM147 main contacts disconnects, A.C. contactor KM246 main contacts closure；After degaussing, signal Con_Ma, Con_Dema are controlled
Low level signal, A.C. contactor KM246 are exported simultaneously, A.C. contactor KM147 main contacts is off-state, magnechuck
Continue to move down a slight distance under the traction of slot pot lifting control mechanism, it is ensured that magnechuck does not hinder slot pot transverse movement；Electricity
Magnetic-disc protection circuit is made of discharge resistance R and C and under-voltage relay KMD 48, and the effect of resistance R and capacitor C is, because
For when magnetizing bothrium pot, sucker stores a large amount of magnetic field energys.Disconnect power supply in a flash, the both ends of magnechuck 43 generate
Biggish self induction electromotive force, damages coil and other electric elements, forms discharge loop with resistance R and capacitor C, it is to utilize
