Dab tsi yog qhov sib txawv ntawm kev tswj cov lus tsa suab thiab plc

Dab tsi yog qhov sib txawv ntawm cov tswj kev txav thiab plc?

Motion maub los yog tus tswj tshwj xeeb los tswj kev ua haujlwm ntawm lub cev muaj zog: piv txwv li, lub cev muaj zog yog tswj los ntawm AC contactor los ntawm kev hloov mus los thiab lub cev muaj zog tsav cov khoom kom khiav mus rau qhov chaw teev tseg thiab tom qab ntawd khiav, lossis siv. lub sij hawm relay tswj lub cev muaj zog tig zoo thiab tsis zoo los yog tig ib pliag kom nres thiab tig ib pliag kom nres.Daim ntawv thov ntawm kev tswj cov lus tsa suab hauv kev ua haujlwm ntawm cov neeg hlau thiab CNC tshuab cov cuab yeej yog qhov nyuaj dua li hauv cov tshuab tshwj xeeb, uas muaj cov qauv yooj yim ntawm kev txav thiab feem ntau hu ua General motion control (GMC).

Cov yam ntxwv ntawm lub zog tswj:

(1) Cov khoom siv sib xyaw ua ke yog qhov yooj yim, ntxig cov tswj kev txav mus rau hauv lub tsheb npav PC, txuas cov kab teeb liab tuaj yeem tsim los ntawm lub kaw lus;

(2) tuaj yeem siv lub PC muaj kev txhim kho software nplua nuj;

(3) Cov cai tswj kev tswj hwm software muaj qhov zoo thoob ntiaj teb thiab kev txav mus los;

(4) Muaj ntau tus kws tshaj lij uas tuaj yeem ua haujlwm txhim kho, thiab kev txhim kho tuaj yeem ua tiav yam tsis muaj kev cob qhia ntau.

Plc yog dab tsi?

Programmable logic controller (PLC) yog ib qho digital arithmetic ua haujlwm hluav taws xob tsim los siv rau hauv ib puag ncig kev lag luam.Nws siv lub cim xeeb programmable uas cov lus qhia ua haujlwm xws li kev ua haujlwm zoo, kev tswj xyuas raws sijhawm, sijhawm, suav thiab lej lej raug khaws cia, thiab ntau hom khoom siv tshuab lossis cov txheej txheem tsim khoom yog tswj los ntawm cov khoom siv digital lossis analog tawm thiab tso tawm.

Cov yam ntxwv ntawm plc

(1) Kev ntseeg siab.Vim tias PLC feem ntau siv ib lub tshuab microcomputer, yog li kev sib koom ua ke siab, ua ke nrog kev tiv thaiv kev sib raug zoo thiab kev kuaj tus kheej muaj nuj nqi, txhim kho kev ntseeg siab ntawm lub cev.

(2) Ib qho yooj yim programming.PLC programming siv relay tswj ntaiv daim duab thiab cov lus txib, tus naj npawb yog tsawg dua li cov lus qhia microcomputer, ntxiv rau PLC qib nruab nrab thiab qib siab, PLC me me tsuas yog kwv yees li 16. Vim yog cov duab ntaiv daim duab thiab yooj yim, yog li yooj yim. rau tus tswv, yooj yim rau siv, txawm tsis xav tau kev txawj ntse hauv computer, tuaj yeem ua haujlwm.

(3) Yooj yim configuration.Vim tias PLC siv lub tsev thaiv cov qauv, tus neeg siv tsuas yog xav tau yooj yim ua ke, ces tuaj yeem hloov pauv txoj haujlwm thiab qhov ntsuas ntawm qhov kev tswj hwm, yog li, tuaj yeem siv rau txhua qhov kev tswj hwm.

(4) Ua kom tiav cov tswv yim / tso zis muaj nuj nqi modules.Ib qho txiaj ntsig zoo tshaj plaws ntawm PLC yog qhov sib txawv ntawm thaj chaw sib txawv (xws li DC lossis AC, hloov pauv ntau, digital kom muaj nuj nqis lossis analog ntau, qhov hluav taws xob lossis tam sim no, thiab lwm yam), muaj cov qauv sib xws tuaj yeem txuas nrog cov khoom siv hauv teb (xws li. raws li cov nyees khawm, keyboards, sensing tam sim no transmitters, lub cev muaj zog pib lossis tswj li qub, thiab lwm yam) ncaj qha, thiab txuas nrog CPU motherboard los ntawm lub tsheb npav.

(5) Ib qho yooj yim installation.Piv nrog rau lub tshuab computer, kev teeb tsa ntawm PLC tsis xav tau chav tshwj xeeb, thiab tsis xav tau kev tiv thaiv nruj.Thaum siv, tsuas yog cov cuab yeej tshawb nrhiav thiab I / O interface davhlau ya nyob twg ntawm tus actuator thiab PLC txuas nrog raug, ces nws tuaj yeem ua haujlwm ib txwm.

(6) Kev khiav ceev ceev.Vim tias PLC tswj tau tswj hwm los ntawm qhov kev ua tiav, yog li txawm tias nws txoj kev ntseeg siab lossis kev khiav ceev, yog qhov kev tswj xyuas kev sib txuas lus tsis tuaj yeem sib piv.Nyob rau hauv xyoo tas los no, kev siv cov microprocessor, tshwj xeeb tshaj yog nrog cov loj ntawm ib nti microcomputer, zoo heev txhim kho lub peev xwm ntawm PLC, thiab qhov sib txawv ntawm PLC thiab microcomputer tswj system tau dhau los ua me thiab me, tshwj xeeb tshaj yog cov qib siab PLC yog li ntawd.

Qhov sib txawv ntawm kev tswj cov lus tsa suab thiab plc:

Kev tswj kev txav feem ntau suav nrog kev tswj ntawm stepper lub cev muaj zog thiab servo lub cev muaj zog.Cov qauv tswj feem ntau yog: tswj cov cuab yeej + tsav tsheb + (stepper lossis servo) lub cev muaj zog.

Cov cuab yeej tswj tau tuaj yeem yog PLC system, tuaj yeem yog cov cuab yeej tshwj xeeb tsis siv neeg (xws li kev tswj cov lus tsa suab, daim npav tswj kev txav).PLC system raws li cov cuab yeej tswj, txawm hais tias muaj qhov yooj yim ntawm PLC system, ib qho kev siv ntau yam, tab sis rau siab precision, xws li - interpolation tswj, rhiab xav tau thaum nws nyuaj ua lossis programming nyuaj, thiab tus nqi yuav siab. .

Nrog kev txhim kho thev naus laus zis thiab kev sib sau ua ke, lub zog tswj tau tshwm sim nyob rau lub sijhawm.Nws solidifies qee qhov dav dav thiab tshwj xeeb tswj kev ua haujlwm hauv nws - xws li cov lus qhia cuam tshuam.Cov neeg siv tsuas yog yuav tsum tau teeb tsa thiab hu rau cov blocks ua haujlwm lossis cov lus qhia, uas txo cov programming nyuaj thiab muaj qhov zoo ntawm kev ua haujlwm thiab nqi.

Nws tseem tuaj yeem nkag siab tias kev siv PLC yog ib qho khoom siv tswj kev txav.Motion maub los yog PLC tshwj xeeb, puv sijhawm rau kev tswj cov lus tsa suab.
