Embodiment
As shown in Figure 1, intelligent control system of down ash removing machine is made up of the temperature sensor of Programmable Logic Controller PLC, the online temperature of collecting device, the speed pickup of gathering Machine for cleaning-out ash spindle motor rotating speed, the PC of regulating frequency converter, the prior data bank of spindle motor rotating speed and storing the prior data bank parameter.Temperature sensor, speed pickup, frequency converter, PC are connected with Programmable Logic Controller PLC corresponding port respectively; Speed pickup adopts photoelectric coded disk.Temperature sensor is imported Programmable Logic Controller .PLC with equipment Current Temperatures data, the photoelectric coded disk gathered with the current rotary speed data of the spindle motor of gathering, and Programmable Logic Controller PLC regulates the spindle motor rotating speed with the prior data bank parameter comparison back of current data and PC storage by frequency converter.
The priori storehouse is set: the priori storehouse is set promptly according to the artificial experience value, collection differing texture, place of production eider down enter Machine for cleaning-out ash under different initial temperatures spindle motor initial speed value, form with database module is used for priori control input parameter, is stored in the PC.Specific as follows:
Come dynamic adjustments spindle motor rotating speed R according to outlet eider down dust content C, built-in temperature T in the ash disposal process.For realizing the optimization configuration of rotating speed R, system at first introduces the priori storehouse, and the real data that operating personnel are obtained for a long time deposits in the knowledge base by classification, specifically, and corresponding to a certain specific place of production and quality eider down, at a certain expection dust content C
0, initial temperature T
0Down, the specific spindle motor rotating speed R of correspondence
0In practical operation, introduce the rule base trigger mode, each bar experience of being about to is converted into form of production and is stored in the knowledge base system, when input eider down and initial parameter satisfy certain rule, promptly trigger specific production system, derive the initial spindle motor rotating speed that needs.
The production system synoptic diagram as shown in Figure 2.The pattern of giving an example of this production is as follows:
(the specific place of production, specific quality) eider down temperature T---〉spindle motor rotating speed R;
The Based Intelligent Control principle of work is: PLC obtains the Current Temperatures data by temperature sensor, by photoelectric coded disk, obtains current spindle motor rotary speed data in real time.When eider down had just entered Machine for cleaning-out ash from last process, temperature was higher, eider down this under the high situation of temperature, be subjected to the damage that high rotating speed spindle motor is brought easily.This moment PLC control of conversion device, frequency converter is regulated spindle motor and is moved with the slow-speed of revolution.Along with the continuous reduction of eider down temperature, PLC improves gradually by Frequency Converter Control spindle motor rotating speed, promotes dedusting effect.When eider down heat radiation, temperature reached low, spindle motor can higher rotation speed move, and this moment, dedusting effect was best.Its funtcional relationship is: establishing temperature is T, and rotating speed is N, under PLC control, and the funtcional relationship F:N=F that forms between N and the T (T).Final dedusting effect is S, then S only and between N and the T formed funtcional relationship F relevant.So S=G (F), wherein, G is a funtcional relationship between F and the S.
The N of the eider down of different batches quality is also different with the funtcional relationship of T.Therefore, PLC will call the priori storehouse parameter Z of storing in the PC in advance in every batch of eider down ash disposal process.Funtcional relationship F between N and the T is adjusted.In this simultaneously, production run each time, final dedusting effect S also has certain retroactive effect to the priori storehouse.According to dust removing effects each time, upgrade Z.Control and Feedback and funtcional relationship are wherein represented feedback and control variable as shown in Figure 3 between each parameter in the annulus, then represent the funtcional relationship between each variable in the Fang Huan.
As shown in Figure 3, concrete each time dust removal process, N is only relevant with T and current funtcional relationship F.N=F (T), F are then relevant with Current Temperatures and priori storehouse Z.Dust removing effects each time, only relevant with F, S=G (F).And final dust removing effects S feeds back to Z again, updates upgrading priori storehouse.Make each time in the production run, can both find only funtcional relationship F, to reach the best dust removing effects of each production.
The parametric compensation of self study upgrades: the self study link in priori storehouse, concrete operations are to satisfy under the special process requirement at eider down Machine for cleaning-out ash exit eider down dust content, if temperature and rotating speed are after second step joint is issued to stationary value, then with mode (the temperature---〉rotating speed of this parameter with production) the former priori knowledge base of inquiry: go to mate production preceding paragraph in the priori storehouse with production preceding paragraph (temperature), if have coupling, in the storehouse of then refreshing one's knowledge consequent (temperature) of production; If there is not coupling, then this rule is write the priori storehouse in new production mode, reach the purpose in the online storehouse that expands knowledge.
