Qhov txawv ntawm HMI thiab PLC yog dab tsi?
Cov Lus Qhia
- 1. HMI human-machine interface:
- 2. PLC programmable logic:
- 3. PLC programmable logic tuaj yeem siv rau kev lag luam automation:
- 4. HMI human-machine interface tuaj yeem siv rau hauv tsheb:
- 5. Qhov txawv ntawm HMI thiab PLC yog dab tsi:
1. HMI human-machine interface:
HMI tseem hu ua human-machine interface, tseem hu ua "human-machine interface". Tib neeg-tshuab interface yog qhov nruab nrab rau kev sib cuam tshuam thiab kev sib pauv ntaub ntawv ntawm qhov system thiab tus neeg siv. Tus neeg siv tuaj yeem cuam tshuam lossis tswj lub cuab yeej. Hom kev sib cuam tshuam suav nrog tab sis tsis txwv rau kev ua haujlwm tswj vaj huam sib luag, uas tseem suav nrog software interface, tawm tswv yim mechanism, thiab lwm yam.
HMI technology tau dhau los ua neeg paub tab. Los ntawm cov nyees khawm ib txwm mus rau tam sim no kov cov ntxaij vab tshaus thiab kev siv tshuab virtual, niaj hnub HMI feem ntau siv hauv kev tswj hwm kev lag luam, tsev ntse, kev tswj tsheb hauv tsheb, khoom siv kho mob thiab lwm yam.
2. PLC programmable logic:
PLC programmable logic tshwj xeeb yog siv hauv kev tswj hwm kev lag luam nrog 4U cov khoos phis tawj. Nws yog feem ntau siv nyob rau hauv kev lag luam ntse tsim, kev lag luam automation ntau lawm kab, kev tswj cov txheej txheem, thiab lwm yam. Nws lub ntsiab logic yog siv cov teeb liab tawm tswv yim thiab tso zis tswj raws li preset logic.
3. PLC programmable logic tuaj yeem siv rau kev lag luam automation:
Qhov thib ob, PLC kuj tuaj yeem siv rau kev tswj cov lus tsa suab, xws li kev hloov pauv ntawm cov cuab yeej siv tshuab, uas feem ntau qhia hauv cov lej. Txoj hauv kev zoo tshaj plaws los tswj cov lus tsa suab yog siv NC, uas yog digital tswj technology. Cov thev naus laus zis no yog ua raws li Asmeskas kev tswj hwm computer technology thiab tam sim no zoo meej heev.
4. HMI human-machine interface tuaj yeem siv rau hauv tsheb:
Human-Machine Interface (HMI) hauv tsheb ua lub luag haujlwm tseem ceeb hauv kev ua kom tus neeg tsav tsheb tseem ceeb thiab tswj xyuas lub tsheb.
Sense of Control: HMI muab cov ntaub ntawv qhia txog lub sijhawm ntawm lub tsheb, xws li kev ceev, roj theem, lub log tsheb siab, thiab lwm yam ntaub ntawv tseem ceeb. Qhov no ua kom tus neeg tsav tsheb paub txog lub tsheb tus mob thiab tuaj yeem txiav txim siab paub, uas txo qhov kev pheej hmoo ntawm kev sib tsoo vim tsis muaj kev paub.
Tswv yim Mechanism: Lub HMI system muaj cov lus qhia hauv daim ntawv ceeb toom, teeb ceeb toom, suab ceeb toom, lossis txawm tias pom kev ceeb toom. Piv txwv li, yog tias lub tsheb dhau qhov kev txwv ceev, HMI system tuaj yeem ceeb toom tus neeg tsav tsheb, txo qhov kev pheej hmoo ntawm kev sib tsoo ceev.
Kev Tiv Thaiv Kev Nyab Xeeb: HMI systems tuaj yeem ua ke nrog cov sensors, koob yees duab, thiab lwm yam thev naus laus zis hauv cov tsheb niaj hnub los saib xyuas cov xwm txheej ntawm kev tsav tsheb tiag tiag. Cov tshuab no tuaj yeem muab cov lus ceeb toom rau tus neeg tsav tsheb txog kev phom sij, xws li cov tsheb nyob ze, cov neeg taug kev, lossis cov teeb meem, pab tiv thaiv kev sib tsoo ua ntej lawv tshwm sim.
5. Qhov txawv ntawm HMI thiab PLC yog dab tsi:
Thaum ob qho tib si HMI (Human-Machine Interface) thiab PLC (Programmable Logic Controller) yog cov khoom tseem ceeb hauv kev lag luam automation, lawv ua haujlwm sib txawv:
HMI (Human-Machine Interface): HMI yog qhov interface uas tib neeg cuam tshuam nrog cov tshuab lossis cov tshuab tswj. Nws nthuav tawm cov ntaub ntawv thiab cov xwm txheej los ntawm lub kaw lus nyob rau hauv ib tus neeg siv-phooj ywg, pom cov hom ntawv, tso cai rau cov neeg ua haujlwm saib xyuas thiab tswj cov txheej txheem. HMIs feem ntau suav nrog touchscreens thiab graphical interfaces uas muab kev hloov kho tshiab thiab tawm tswv yim tiag tiag. Lub hom phiaj ntawm HMI yog nyob ntawm cov neeg siv kev sib cuam tshuam, cov xwm txheej hauv lub cev, thiab kev ua haujlwm yooj yim. Muaj vaj huam sib luag PC muab kev daws teeb meem zoo rau kev tsim HMI systems.
PLC (Programmable Logic Controller): PLCs yog cov khoos phis tawj tshwj xeeb siv los tswj thiab ua kom cov txheej txheem kev lag luam. Lawv ua cov txheej txheem ua ntej los saib xyuas cov khoom nkag (xws li sensors) thiab tswj cov khoom tawm (xws li motors, teeb, lossis li qub). PLCs tswj xyuas qhov tseeb ntawm cov tshuab thiab cov txheej txheem, ua haujlwm raws li cov lus qhia thiab cov lus qhia. Lawv yog tsim los rau robustness thiab kev ntseeg siab nyob rau hauv hnyav industrial puag ncig.
Cov ntsiab lus:
- HMI yog lub interface rau tib neeg cov neeg ua haujlwm saib xyuas thiab cuam tshuam nrog lub kaw lus. IP65 Kov Vaj Huam Sib Luag PC tuaj yeem ua tau zoo tagnrho rau kev lag luam sab nraum zoov.
- PLC yog tus maub los uas txheej txheem inputs thiab executes commands tswj industrial machines thiab systems.
Hauv kev teeb tsa ib txwm, PLC ua tiav qhov kev tswj hwm kev tswj hwm, thaum HMI tso cai rau cov neeg ua haujlwm pom cov xwm txheej thiab hloov kho raws li xav tau. Rau cov kev daws teeb meem HMI ntau dua, koj tuaj yeem tshawb xyuas ntau hom kev lag luam vaj huam sib luag PCs, xws li 8-nti Industrial Vaj Huam Sib Luag PC, 10-nti Industrial Vaj Huam Sib Luag PC, 12-nti Industrial Vaj Huam Sib Luag PC, los yog 15-nti Industrial Vaj Huam Sib Luag PC. Rau cov duab loj, cov kev xaiv zoo li cov 17-nti Industrial Vaj Huam Sib Luag PC thiab 19-nti Industrial Vaj Huam Sib Luag PC tej zaum yuav haum. Yog tias koj xav tau ib qho screen loj dua, xav txog qhov 21-nti Industrial Vaj Huam Sib Luag PC.
Qhov no yuav txhim kho koj HMI system nrog cov kev daws teeb meem uas muaj zog dua thiab muaj peev xwm ua tau raws li kev xav tau tshwj xeeb hauv kev lag luam.
