Hauv kev lag luam ntim khoom, lub thawv ntim ntim tshuab (tseem hu ua ton hnab ntim tshuab) muaj npe nrov rau lawv cov kev ua haujlwm siab thiab muaj peev xwm loj. Txawm li cas los xij, thaum lub sijhawm ua haujlwm tiag tiag, cov neeg ua haujlwm feem ntau ntsib qhov teeb meem nyuaj: tom qab lub tshuab nkag mus rau theem "ceev noj", muaj kev nyiam rau qhov sib txawv ntawm qhov hnyav, ua rau cov khoom dhau los lossis tsis ua raws li - ntim khoom. Qhov tshwm sim no tsis tsuas yog cuam tshuam rau kev ntim khoom raug, tab sis kuj tseem tuaj yeem ua rau cov khoom pov tseg ntawm cov khoom siv raw thiab kev poob qis hauv kev tsim khoom. Kab lus no yuav tshawb xyuas ntau yam ua rau tom qab qhov tshwm sim no, txhais nws los ntawm ntau qhov ntev xws li cov yam ntxwv ntawm cov khoom siv, cov khoom teb, sensor rhiab heev, thiab tswj logic.
1. Dynamic hloov ntawm cov khoom ntws yam ntxwv
Lub hom phiaj tseem ceeb ntawm theem ntawm kev ntxiv cov ntaub ntawv sai sai yog ua kom qhov hnyav sai sai siv cov khoom siv loj thiab ua kom lub voj voog tag nrho. Txawm li cas los xij, theem no feem ntau yog qhov tseem ceeb ntawm qhov yuam kev, vim tias lub cev lub zog ntawm cov khoom hloov pauv thaum lawv cov txheej txheem poob qis:
Kev cuam tshuam ntawm huab cua ntws thiab plua plav: Thaum muaj ntau cov granular los yog hmoov- zoo li cov ntaub ntawv raug tso tawm los ntawm qib siab - qib silo, muaj huab cua muaj zog tam sim no raug tsim tawm. Qhov no tsis tsuas yog ua rau qee cov ntaub ntawv hnyav ya mus, tab sis kuj ua rau tsis ruaj khov ntawm cov khoom ntws nws tus kheej, uas ua rau siab - lub suab nrov zaus hauv qhov ceeb thawj tau txais los ntawm lub ntsuas qhov hnyav.
2. Choj Tsim thiab Rat-Qhov Phenomenon: Thaum lub sij hawm tawm sai, kev sib txhuam quab yuam ntawm cov khoom thiab cov phab ntsa ntawm qhov chaw cia khoom nce, uas tuaj yeem ua rau tsim "choj" (piv txwv li, cov khoom tau thaiv hauv cov duab kos) saum lub qhov hluav taws xob tawm lossis tsim ntawm "rat-qhov" ntawm qhov nruab nrab (nrog accum phery). Qhov dej tsis sib xws no yuav ua rau qhov nrawm nrawm nrawm nrawm heev, yog li cuam tshuam qhov kev tswj tsis tu ncua ntawm qhov system.
3. Kev kho qhov sib txawv: kev pub mis ceev feem ntau yog kev pub noj ceev. Nws yuav siv sij hawm qee lub sij hawm rau cov khoom poob los ntawm qhov chaw nres nkoj pub rau hauv lub hnab (piv txwv li, qhov siab ntawm cov huab cua ntawm cov khoom). Txawm hais tias tus maub los ua "automatic gap them", yog tias cov khoom ntws nrawm dhau, cov txheej txheem them nyiaj yuav tsis tuaj yeem ua raws li qhov tseeb qhov hnyav hloov, uas ua rau qhov hnyav sib txawv ntawm cov nqi teev thaum noj zaub mov raug tso tseg tom qab.
II. Kev sib tw sib tw ntawm cov cuab yeej siv tshuab thiab tswj qhov system
Sib nrug los ntawm cov xwm txheej cuam tshuam nrog cov ntaub ntawv lawv tus kheej, cov lus teb ceev ntawm cov cuab yeej siv tshuab thiab kev sib koom tes ntawm cov kev tswj xyuas ntse kuj tseem ceeb heev:
Inertia qeeb ntawm pneumatic actuators: Ntau lub hnab- ntim tshuab siv pneumatic li qub lossis rooj vag los tswj cov txheej txheem pub mis. Qhov txuas ntxiv thiab thim rov qab ntawm lub tog raj kheej muaj cov tshuab qeeb qeeb, nrog rau millisecond - theem lag luam ntawm qhov tau txais lub teeb liab kaw thiab txiav tag nrho cov khoom ntws. Nyob rau hauv siab -ceev filling tej yam kev mob, txawm ob peb lub vib nas this los yog ib feem ntawm ib tug thib ob ntawm ncua sij hawm txhais tau tias cov ntaub ntawv ntxiv yuav poob rau hauv lub hnab, ua rau overfilling.
2. Lub raj mis ntawm lub zog teb ntawm lub ntsuas qhov hnyav: Siab - qhov ntsuas qhov ntsuas qhov tseeb xav tau lub sijhawm kom ruaj khov ntawm kev nyeem ntawv. Nyob rau hauv ib puag ncig siab - cuam tshuam nrog kev pub noj sai, lub sensor yuav nyob twj ywm hauv lub xeev oscillating thiab tsis tuaj yeem muab qhov tseeb qhov hnyav tam sim ntawd. Yog hais tias lub kaw lus tswj tau kuaj ntxov dhau los lossis lig dhau lawm, qhov yuam kev yuav tshwm sim.
3. Kev tsis sib haum PID tsis zoo: Hauv kev tswj tsis siv neeg, yog tias qhov sib npaug, qhov sib piv, thiab cov khoom siv sib txawv tau ua kom zoo rau kev pub mis qeeb qeeb, thaum hloov mus rau hom kev pub noj ceev, lub kaw lus yuav oscillate nyob ib ncig ntawm lub hom phiaj tus nqi vim cov tshuaj tiv thaiv ntau dhau, ua rau nws nyuaj rau converge smoothly.
III. Muaj peev xwm cuam tshuam los ntawm Environmental thiab Maintenance Factors
Kev cuam tshuam sab nraud ntawm kev co: Lub zog loj heev uas tsim los ntawm kev pub noj sai sai yuav raug xa mus los ntawm tus ncej mus rau qhov hnyav. Yog tias lub hauv paus uas cov cuab yeej raug teeb tsa tsis ruaj khov txaus, lossis muaj lwm yam khoom siv loj ua haujlwm nyob ib puag ncig, cov khoom siv hluav taws xob sab nraud yuav raug txhais yuam kev los ntawm lub sensor raws li kev hloov pauv hauv qhov hnyav.
2. Kev sib hloov ntawm cov khoom sib txuas ntawm cov khoom muag muag: Cov kev sib txuas muag muag ntawm cov khoom ntim khoom thiab cov khoom noj khoom haus (xws li cov roj hmab hoses lossis cov hnab canvas) yuav muaj lub zog tensile tseem ceeb thaum cov khoom ntws los ntawm kev kub ceev. Kev hloov tsis tu ncua ntawm qhov nro no yuav cuam tshuam ncaj qha rau lub cev hnyav, qhia txog kev ntsuas qhov yuam kev.
Hauv kev xaus, qhov sib txawv ntawm cov teeb meem thaum lub sij hawm pub mis sai ntawm lub hnab - hauv - lub thawv ntim tshuab yog qhov tshwm sim ntawm kev sib cuam tshuam ntawm cov khoom siv, cov lus teb, thiab kev tswj cov algorithms. Txhawm rau txhim kho qhov teeb meem no, nws tsis yog ib qho teeb meem ntawm kev kho ib lub pob khawm nkaus xwb; es, nws yuav tsum tau saib xyuas ntawm cov dej noo thiab particle loj piv ntawm cov ntaub ntawv, optimizing lub kaw ib theem zuj zus ntawm pneumatic li qub, kho cov dynamic teb tsis tau ntawm tus maub los, thiab kom ruaj khov installation ntawm cov khoom. Tsuas yog los ntawm kev sib xyaw ua ke ntawm cov neeg kho tshuab qhov tseeb nrog cov kev txawj ntse algorithms tuaj yeem ua cov txheej txheem ntim khoom yog "ceev" thiab "raug".
