Support the working frequency of the frequency converter under online setting different mode in machine interface.
Three kinds of operating modes are arranged in dryer intelligence control system：Intelligent mode, manual mode and emergency shutdown pattern.
Intelligent mode, which is divided into grain, intelligence, dries, periodically dries, putting out cereal；Manual mode divides wind turbine start and stop, vibration start and stop, elevator to open
Stop, throwing disc start and stop；One key emergency stop of emergency shutdown pattern.
Accordingly, the control panel of switch board is arranged with first group of function key, second group of function key, third group from top to bottom
Function key, wherein first group of function key includes that system operation instruction, emergent stopping button, intelligence/manual key and alarm are removed
Button, second group of function key are intelligent mode control button group, including dry button into grain button, intelligence drying button, timing
With button of putting out cereal, the third group function key includes manual mode button, including throwing disc motor start and stop button, promotion motor start and stop
Button, wind turbine start and stop button, vibrating motor start and stop button.
Wherein, first group of functions of functional keys is as follows：System operation key, be used to indicate it is bright when system operation, i.e. system electrification,
It goes out when system cut-off.Emergent stopping button, using mushroom head spinning reduction key, when pressing, all sub- equipment of system are out of service.
Third group functions of functional keys is as follows：Throwing disc button, start and stop throwing disc motor；It promotes button and is used for start and stop elevator motor；Wind turbine is pressed
Key is used for start and stop blower motor, and vibration button is used for starting and stopping vibration motor.
First group of indicator light (malfunction indicator lamp-red light)：Be arranged throwing disc motor, elevator, wind turbine, vibration indicating fault
Effect.Second group of indicator light (run indicator-green light)：Be arranged throwing disc motor, elevator, wind turbine, vibration operation instruction make
With.
The effect of other buttons is specific as follows：
Into under grain pattern, only start throwing disc motor, other motors, which do not start, and blocking rotary type level detector is alarmed waits responding.When
Grain warehouse entry is to when buying securities with all one's capital, and system can prompt to buy securities with all one's capital and warning reminding.Pay attention to：Only starts into grain function and (press key pressing into grain)
Afterwards, whether grain buys securities with all one's capital in system ability intelligent decision storehouse, can just trigger alarm.A Self-resetting band is used into grain button
The button of lamp starts when pressing Self-resetting button, then is shut down by primary.
Under intelligent drying pattern, all motors are according to certain sequence start and stop, boot sequence：Throwing disc starts, and is carried after t1
The machine of liter starts, and vibrating motor starts simultaneously with wind turbine after t2.System will be set according to the grain moisture content value actually measured and user
Target moisture value be compared, when the time of the continuous t3 of the moisture value currently surveyed is still less than target moisture value, system incite somebody to action from
Dynamic to shut down, the sequence that motor is closed is：Vibrating motor is closed, and elevator is closed after t2, and throwing disc is simultaneously closed off with wind turbine after t2.Note
Meaning：Because moisture transducer link establishment and data upload need certain time (about 2 minutes or so), only when moisture transducer refers to
Show lamp greening (sensor indicator light on touch screen parameter interface), and (wind turbine is not when target moisture value is less than the moisture value of actual measurement
Before startup, actual measurement moisture value in real time can be observed by touch screen expert interface), intelligence dries button and just responds user's operation.
Under intelligent drying pattern there are two types of halt modes：One kind shutting down (the interim interruption in scene when pressing Self-resetting key again
Drying)；It is a kind of to be shut down using judgement moisture figure, after grain moisture content reaches preset value and continues t3, stop drying.Intelligence is dried
Dry button uses a function button of the Self-resetting with lamp, starts when pressing Self-resetting button, then is shut down by primary triggering.
Under timing drying pattern, setting timing and opening timing work(on touch screen timing function setting interface
Can, start timing and dry, system will start each motor successively, and boot sequence is：Throwing disc starts, and elevator starts after t1, t2
Vibrating motor starts simultaneously with wind turbine afterwards.After timing reaches, by autostop, the sequence that motor is closed is system：It shakes
Dynamic motor is closed, and t2 elevators are closed, and t2 throwing discs are simultaneously closed off with wind turbine.Pay attention to：On touch screen on timing function setting interface
Timing function is not switched on, at this time start timing dry, system will not autostop, need user press again timing drying by
Key, system can just trigger shutdown.
Under timing drying pattern there are two types of halt modes：One kind shutting down (the interim interruption in scene when pressing Self-resetting key again
Drying)；A kind of to be shut down using timing, when timing terminates, equipment stops drying.Timing drying button uses a Self-resetting
Function button with lamp starts when pressing Self-resetting button, then is shut down by primary triggering.
Grain heat-drying terminates to put out cereal, and starts into grain function, and system will first start elevator, Vibration on Start-up motor after t2.
After putting out cereal, close into grain function, system will first close vibrating motor, and t2 turns off elevator.Button of putting out cereal uses one
Button of the Self-resetting with lamp, starts when pressing Self-resetting button, then stops by primary.
It presses (press key lamp is bright) after intelligence/manual key, system will switch to manual mode.Allow user single under the pattern
Each motor of only start and stop.By the Self-resetting band lamp function button of intelligent mode/hand pattern switching, switch two kinds of Working moulds
Formula.Under manual mode, indicator light is bright.Under intelligent mode, indicator light goes out.
All sub- equipment (each motor) of equipment be closed under when, intelligence/manual key just responds operation.I.e.
Under current operation mode, any one or more electric machines tests are being run, and mode switching key is not responding to operate.
An emergency shutdown button is arranged in this system, and all motors and frequency converter instantaneously stop work when pressing emergency stop button
Make.
The a set of perfect alarm system of this Control System Design, when electrical fault, into grain buy securities with all one's capital or dry completion when, can
Trigger alarm mechanism.When triggering system alarm, alarm equipment alarm, while can prompt to trigger the correlation of this alarm on display screen
Information.
The reason of function is removed in system design alarm, and system automatic identification generates this alarm, and can be removed by alarming
Button, soft closing alarm bell only close this triggering alarm, are not turned off alarm mechanism, not influencing follow-up other reasons causes
Alarm.
It is used in addition, (drying into grain, intelligence, periodically drying, putting out cereal) between intelligence and manual mode and intelligent mode
Function interlocking design when that is, system is in certain operating mode, removes emergency stop button, and other mode keys are not responding to operate.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
