Lub PLC system uas siv rau hauv cov tshuab ntim khoom yog dab tsi?

Rau kev vam meej hauv ib puag ncig kev lag luam niaj hnub no uas nrawm heev, kev tswj cov txheej txheem txhim khu kev qha thiab kev ua haujlwm tsis siv neeg yog qhov tseem ceeb heev. Lub tshuab ntim khoom siv PLC ua rau cov nyiaj tau los ntawm kev tsim khoom ntau ntxiv. Nrog PLC, cov haujlwm nyuaj yuav yooj yim dua rau kev teeb tsa thiab tswj hwm. PLC systems yog qhov tseem ceeb rau kev vam meej ntawm ntau yam lag luam, suav nrog kev ntim khoom, tshuaj lom neeg, khoom noj, thiab dej haus. Thov nyeem ntxiv kom nkag siab ntxiv txog PLC system thiab nws txoj kev sib raug zoo rau cov tshuab ntim khoom.

Lub kaw lus PLC yog dab tsi?

PLC txhais tau tias "programmable logic controller," uas yog nws lub npe tag nrho thiab yog. Vim tias cov thev naus laus zis ntim khoom tam sim no tau dhau los ua tshuab thiab tsis siv neeg, qhov ntau ntawm cov khoom uas raug ntim yuav tsum yog qhov tseeb, vim qhov no muaj feem cuam tshuam rau cov khoom muaj txiaj ntsig thiab kev lag luam.

Feem ntau cov chaw tsim khoom siv cov kab sib dhos ua ke uas tsis siv neeg tag nrho hauv qhov xwm txheej no. Lub kaw lus PLC yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov kab sib dhos no. Txij li thaum thev naus laus zis tau nce qib, yuav luag txhua lub tshuab ntim khoom saum toj kawg nkaus tam sim no muaj PLC tswj vaj huam sib luag, ua rau lawv yooj yim siv dua li yav dhau los.

Cov hom PLC

Raws li hom zis uas lawv tsim tawm, PLCs raug cais ua pawg raws li hauv qab no:

· Cov zis transistor

· Triac tso zis

· Cov zis tawm ntawm qhov chaw xa xov

Cov txiaj ntsig ntawm PLC system nrog lub tshuab ntim khoom

Muaj ib lub sijhawm uas lub tshuab PLC tsis yog ib feem ntawm lub tshuab ntim khoom, xws li lub tshuab ntim khoom siv tes. Yog li ntawd, xav tau cov neeg ua haujlwm ntxiv kom paub tseeb tias txoj haujlwm tau ua tiav. Txawm li cas los xij, qhov tshwm sim thaum kawg yog qhov poob siab. Kev siv sijhawm thiab nyiaj txiag yog qhov loj heev.

Txawm li cas los xij, nws txhua yam tau hloov pauv nrog kev tuaj txog ntawm PLC systems ntsia rau hauv lub tshuab ntim khoom.

Tam sim no, ntau lub tshuab ua haujlwm tsis siv neeg tuaj yeem ua haujlwm ua ke tau zoo dua. Koj tuaj yeem siv lub tshuab PLC los ntsuas qhov hnyav ntawm cov khoom kom raug, tom qab ntawd ntim lawv rau kev xa khoom. Tsis tas li ntawd, cov tshuab muaj lub vijtsam tswj PLC uas koj tuaj yeem hloov kho cov hauv qab no:

· Qhov ntev ntawm lub hnab

· Ceev

· Cov hnab saw hlau

· Hom Lus thiab Code

Kub

· Ntau ntau

Nws ua rau tib neeg muaj kev ywj pheej thiab ua rau txhua yam yooj yim thiab ncaj nraim rau lawv siv.

Ntxiv mus, PLCs tau tsim los kom kav ntev, yog li lawv tuaj yeem tiv taus cov xwm txheej hnyav, suav nrog cua sov siab, hluav taws xob buzzing, huab cua noo, thiab kev co. Cov tswj logic tsis zoo li lwm cov khoos phis tawj vim lawv muab cov tswv yim / tso zis loj (I / O) rau kev tswj hwm thiab saib xyuas ntau lub actuators thiab sensors.

Lub tshuab PLC kuj tseem muaj ntau yam zoo rau lub tshuab ntim khoom. Qee qhov ntawm lawv yog:

Yooj yim siv

Ib tug kws sau computer programmer tsis tas yuav sau PLC code. Nws yog ua kom yooj yim, thiab koj tuaj yeem kawm tau hauv ob peb lub lis piam. Vim nws siv:

· Cov duab qhia txog ntaiv tswj hwm Relay

· cov lus txib

Thaum kawg, cov duab kos ntaiv yog qhov yooj yim to taub thiab siv tau vim lawv qhov pom kev.

Kev ua tau zoo tas li

Cov PLCs siv cov microcomputers ib leeg-chip, ua rau lawv sib koom ua ke zoo heev, nrog rau cov circuitry tiv thaiv thiab cov haujlwm kuaj mob tus kheej uas ua rau lub kaw lus muaj kev ntseeg siab.

Kev teeb tsa yooj yim

Tsis zoo li lub khoos phis tawj, kev teeb tsa PLC tsis xav tau chav khoos phis tawj tshwj xeeb lossis kev ceev faj tiv thaiv.

Kev nce ceev

Vim tias kev tswj hwm PLC raug siv los ntawm kev tswj hwm qhov kev pab cuam, nws tsis tuaj yeem piv rau kev tswj hwm relay logic txog kev ntseeg tau lossis kev ua haujlwm ceev. Yog li, lub kaw lus PLC yuav ua kom koj lub tshuab ceev dua los ntawm kev siv cov tswv yim ntse, logical.

Ib qho kev daws teeb meem pheej yig

Cov txheej txheem logic raws li relay, uas tau siv yav dhau los, kim heev dhau sijhawm. Cov tswj hwm logic programmable tau tsim los hloov cov txheej txheem tswj hwm raws li relay.

Tus nqi ntawm PLC zoo ib yam li kev nqis peev ib zaug xwb, thiab kev txuag nyiaj ntau dua li cov kab ke relay, tshwj xeeb tshaj yog hais txog lub sijhawm daws teeb meem, cov sijhawm ua haujlwm ntawm engineer, thiab cov nqi teeb tsa thiab txij nkawm, yog qhov tseem ceeb heev.

Kev sib raug zoo ntawm PLC systems thiab kev lag luam ntim khoom

Raws li koj twb paub lawm, PLC systems ua kom cov tshuab ntim khoom ua haujlwm tau zoo; yog tsis muaj automation, lub tshuab ntim khoom tsuas tuaj yeem xa tau ntau yam xwb.

PLC siv dav hauv kev lag luam ntim khoom thoob ntiaj teb. Qhov yooj yim uas nws tuaj yeem ua los ntawm cov engineers yog ib qho ntawm nws ntau qhov zoo. Txawm hais tias PLC tswj cov kab ke tau muaj nyob rau ntau xyoo lawm, tiam tam sim no yog tsim los ntawm kev siv cov thev naus laus zis tshiab. Ib qho piv txwv ntawm lub tshuab uas siv hom kev tswj hwm no yog lub tshuab ntim khoom tsis siv neeg linear weigher. Kev koom ua ke ntawm PLC tswj system thiab txhim kho nws cov kev ua haujlwm zoo yog qhov tseem ceeb ntawm feem ntau cov tuam txhab tsim khoom ntim khoom.

Vim li cas cov chaw tsim khoom siv lub tshuab ntim khoom siv PLC system?

Feem ntau cov chaw tsim khoom siv tshuab ntim khoom tau tsim lawv cov tshuab txhawb nqa PLC system vim muaj ntau yam laj thawj. Ua ntej, nws coj kev siv tshuab los rau hauv lub Hoobkas ntawm tus neeg siv khoom, txuag cov sijhawm ua haujlwm, lub sijhawm, cov khoom siv raw, thiab kev siv zog.

Qhov thib ob, nws ua rau koj cov khoom tsim tau zoo dua, thiab koj muaj ntau yam khoom ntxiv, npaj txhij xa tuaj rau koj hauv lub sijhawm luv luv.

Thaum kawg, nws tsis kim heev, thiab tus neeg ua lag luam pib tshiab tuaj yeem yuav lub tshuab ntim khoom nrog cov peev xwm PLC ua ke tau yooj yim.

Lwm yam kev siv ntawm PLC systems

Cov lag luam sib txawv xws li cov hlau thiab tsheb, cov lag luam tsheb thiab tshuaj lom neeg, thiab lub zog fais fab txhua tus siv PLCs rau ntau lub hom phiaj. Qhov muaj txiaj ntsig ntawm PLCs nthuav dav heev thaum cov thev naus laus zis uas nws siv tau nce qib.

PLC kuj tseem siv rau hauv kev lag luam yas los tswj kev txhaj tshuaj molding thiab lub tshuab corrugation tswj system, silo pub mis, thiab lwm yam txheej txheem.

Thaum kawg, lwm cov teb uas siv PLC systems suav nrog tab sis tsis txwv rau:
