I. Kev qhia lus
Hauv teb ntawmKev Tswj Xyuas, qhov kev xaiv ntawmtus maub losMuaj kev cuam tshuam tseem ceeb heev rau qhov ruaj khov, kev ntseeg tau thiab ua haujlwm ntawm cov txheej txheem. Ntawm ntau tus tswj,Plc ( Lub caj lajLogic maub los) yog siv dav hauv ntau yamMuaj AutomationCov xwm txheej vim nws cov txiaj ntsig tshwj xeeb, thaumMicrocontrollersyog qhov tsawg. Daim ntawv no yuav tham txog nthuav dav vim li cas PLCS raug xaiv dua li microcontrollers rauyam muaj hauj lwmKev tswj hwm thiab muab cov nyeem nrog kev nkag siab tob los ntawm kev tshawb xyuas cov yam ntxwv, thiab ua kom muaj zog thiab tsis muaj zog ntawm ob qho tib si siv.
Ii. Txheej txheem cej luam ntawm cov yam ntxwv ntawm PLCS thiab MicroControllers
Cov yam ntxwv PLC
Plc yog lub hom phiaj dav dav tsim rau kev tswj kev lag luam nrog cov nta tseem ceeb no:
Muaj zog ruaj khov:PLC Adops tsauyam kho vajtseThiab lub sijhawm ua haujlwm tiag tiag, uas muaj kev ruaj khov siab thiab muaj kev ntseeg tau, thiab tuaj yeem khiav ruaj khov rau lub sijhawm ntev, uas yog qhov tsim nyog rau kev ua haujlwm ntev hauv kev lag luam ntau lawm.
Lub cajmeem yog qhov yooj yim:Plc Kev PabcuamSiv cov lus programming zoo ib yam li cov kab kos ntaiv, yooj yim to taub thiab kawm,lub cavTuaj yeem sai pib nrog lub cajmeem.
Kev loj hlob luv luv:PLC Hardware tau ntim, tsuas yog lub cajmeem tuaj yeem ua tiavTswjhwm systemKev loj hlob, tshem tawm cov sijhawm los tsim kho vajtse, tuaj yeem txo qis dua qhov kev txhim kho qhov project.
Yooj yim los tswj:Plc system modularity nyob rau hauv dav dav, teeb meem tuaj yeem yog qhov tseeb nyob rau qhov tshwj xeeb tsis sib thooj module rau saikev kholossis hloov.
Cov yam ntxwv ntawm MicroController
Microcontroller, ntawm qhov tod tes, yog ib qhoncig lub vojrcuitaltws ntooNrog cov yam ntxwv hauv qab no:
Yooj taus:Microckontroller tuaj yeem tsim tau raws li cov kev xav tau tiag tiag ntawm cov kho vajtse, sau cov kev pab tsim nyog kom ua tiav kev tswj hwm tau yooj yim dua, siv tau rau kev tswj hwm kev tswj hwm.
Tus nqi qis:Tus nqi kho vajtse ntawm microcontroller tsis tshua muaj, uas haum rau qee qhov nqi them nqi thov kev pab cuam.
III. Qhov Zoo Ntawm Plc Hla MicroController Hauv Kev Tswj Khoom
Muaj Ib Cheeb Tsam Ib puag ncig Kev Hloov Kho
Muaj cov chaw nyob ib puag ncig yog qhov nyuaj, muaj hmoov av, siv cov khoom siv hluav taws xob tshwj xeeb, yog li nws tuaj yeem ua haujlwm ruaj khov nyob rau hauv ib puag ncig hnyav. Nyob rau hauv kev sib piv, txawm hais tias microcontroller tseem tuaj yeem hloov kho qee qhov chaw muaj kev lag luam, tab sis hais txog kev ruaj ntseg thiab kev ntseeg tau piv nrog PLC tseem yog qhov loj loj.
Feature-nplua nuj thiab thev taus
PLC muaj lub tsev qiv ntawv muaj zog ntawm cov haujlwm muaj zog, suav nrog timers, ib txwm qhib, feem ntau kaw, tswj kev tsa suab,tus phab ntsaKev tau txais, high-ceev mem tes thiab lwm cov lus txib, tuaj yeem ua tau ntau yam ntawm cov kev tswj hwm kev tswj hwm. Nyob rau tib lub sijhawm, PLC muaj ntau txoj haujlwm nthuav dav kev nthuav dav, cov qauv sib txawv rau cov kev xav tau sib txawv, thiab ntsaws thiab ua si yooj yim heev. Ntawm qhov tod tes, microcontroller xav tau customized thiab tsim raws li cov kev xav tau tshwj xeeb thiab kev nthuav dav ib zaug thiab tsis zoo.
Yooj yim siv thiab kev txhim kho
Plc cov lus programming tau yooj yim kawm thiab siv tau yooj yim, engineers tuaj yeem pib pib lub hom phiaj. Nyob rau tib lub sijhawm, PLC yuav tau encapsulated rau hauv ib tug ua haujlwm thaiv cov lus qhia, programming ncaj qha hu, zoo txhim kho kev txhim kho efficiency. Lub cajmeem ntawm microckontroller yog cov txheej txheem sib txawv, uas xav tau kev txawj siab thiab tus nqi them. Ib qho ntxiv, plc cov khoom seem yog muaj ntau thiab yooj yim tswj thiab hloov, thaum microcontroller cov khoom seem tsis tshua muaj zog.
Kev nyab xeeb thiab kev ntseeg tau
PLC kuj muaj txuj ci nyob hauv kev nyab xeeb. Nws tau lees paub lub kaw lus kaw lub tsev, uas muaj qib siab ntawm kev ruaj ntseg thiab tuaj yeem tiv thaiv kev tawm tsam sab nraud thiab kev ua haujlwm tsis raug cai. Nyob rau tib lub sijhawm, cov khoom siv kho vajtse thiab software ntawm PLC tau sim nruj thiab paub tseeb, thiab muaj qib siab ntawm kev ntseeg tau. Ntawm qhov tod tes, kev ruaj ntseg ntawm microcontroller yog tus nqi qis, uas yog qhov yooj yim yuav tsum tau tawm tsam thiab cuam tshuam los ntawm kev tawm tsam sab nraud.
Tus nqi thiab cov nyiaj pab
Txawm hais tias tus nqi kho vajtse ntawm microcontroller yog qhov tsawg dua, vim tias microcontrolling kev txawj ntse thiab nqi zog ntau dua los tswj, uas yuav nce tag nrho cov nqi ntawm lub system. Thaum Plc muaj me ntsis cov khoom siv kho vajtse me ntsis, nws txoj kev txhim kho, kev kho yooj yim thiab ruaj khov ua rau tag nrho cov system ua tau zoo.
IV. Tag
Txhawm rau kom lub ntsab lug, cov laj thawj xaiv plc dhau ntawm cov microcontroller hauv kev lag luam kev nyab xeeb feem ntau suav nrog kev siv hauv qab no, kev nyab xeeb thiab kev ntseeg siab thiab muaj txiaj ntsig thiab txiaj ntsig. Yog li ntawd, nyob rau hauv thaj teb ntawm kev tswj hwm kev lag luam, plc tau dav siv nyob rau hauv ntau yam kev lag luam chration scarios, ua ib qho kev tswj hwm automationatis, kev tswj hwm cov khoom siv tsis tseem ceeb. Tau kawg, microcontrollers kuj muaj lawv cov txiaj ntsig tshwj xeeb thiab daim ntawv thov kev daws teeb meem, tab sis PLC tseem yog qhov kev tswj hwm uas nyiam tshaj plaws hauv kev tswj cov kev tswj.
