Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm.
Hais txog qhov no, vim li cas thiaj yuav siv tau los ntawm PLC?
Tom qab tag nrho, lub hom phiaj tseem ceeb ntawm a plc yog hloov "lub ntiaj teb tiag" relays . Peb tuaj yeem xav txog ib relay raws li ib tug electromagnetic hloov. Siv ib tug voltage rau lub kauj thiab ib tug magnetic teb yog generated. Qhov no magnetic teb nqus cov neeg ntawm lub relay hauv kev ua rau lawv ua kev sib txuas.
Ib yam li ntawd, qhov txawv ntawm PLC thiab DCS yog dab tsi? PLC stands rau Programmable Logic Controller. Nws yog tus tswj (lub hlwb) ntawm tsob nroj uas siv tshuab Automation. Hauv luv luv, PLC yog tus tswj qhov ntawd DCS yog tswj raws tu qauv.
Xav txog qhov no, dab tsi yog qhov relay hauv PLC?
Relay yog ib qho kev hloov kho tshuab uas siv cov teeb liab electromagnetic los khiav lag luam, feem ntau yog siv nyob rau hauv high voltage circuits los yog mus cuag ntau yam circuits uas tau tswj los ntawm ib lub teeb liab. Qhov twg as PLC (Programmable Logic Controller) yog dav siv rau kev lag luam lub hom phiaj uas cuam tshuam nrog Machine.
Qhov txawv ntawm PLC thiab Scada yog dab tsi?
Qhov tseem ceeb qhov sib txawv ntawm a PLC (los yog Programmable Logic Controller) thiab SCADA (Kev Tswj Xyuas Kev Tswj Xyuas thiab Kev Tshawb Fawb Cov Ntaub Ntawv) yog qhov tseeb tias a PLC yog hardware thiab SCADA yog (feem ntau) software, tab sis ib txhia yuav cam hais tias SCADA yog cov nroj tsuag tswj tag nrho siv cov khoom siv kho vajtse thiab software.

Dab tsi yog qhov zoo sib xws ntawm kev xav thiab kev xav?
Kev xav thiab kev nkag siab yog ob txoj kev sib cais uas muaj feem cuam tshuam zoo heev. Kev hnov lus yog cov tswv yim hais txog lub ntiaj teb lub cev tau txais los ntawm peb cov receptors sensory, thiab kev nkag siab yog cov txheej txheem uas lub hlwb xaiv, npaj, thiab txhais cov kev xav no
Dab tsi yog qhov sib txawv ntawm cov ntaub ntawv sib sau ua ke thiab cov ntaub ntawv tsis sib xws?
Kev sib sau cov ntaub ntawv yog sau thiab sau cov ntaub ntawv; kom disaggregate cov ntaub ntawv yog rhuav tshem cov ntaub ntawv sib sau ua ke rau hauv cov khoom siv lossis cov ntaub ntawv me me
Dab tsi yog qhov txawv ntawm kev sib raug zoo unary kev sib raug zoo binary thiab kev sib raug zoo ternary?
Kev sib raug zoo tsis sib xws yog thaum ob tus neeg koom hauv kev sib raug zoo yog tib lub koom haum. Piv txwv li: Cov ncauj lus yuav yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm. Kev sib raug zoo ternary yog thaum peb lub koom haum koom nrog kev sib raug zoo
Dab tsi yog qhov txawv ntawm kev sib raug zoo thiab tsis muaj kev sib raug zoo databases?
Qhov sib txawv loj ntawm lawv yog li cas lawv tuav cov ntaub ntawv. Relational databases are structured.Non-relational databases are document-oriented. Qhov no hu ua cov ntaub ntawv hom cia tso cai ntau 'qeb' ntawm cov ntaub ntawv khaws cia hauv ib qho kev tsim lossis Cov Ntaub Ntawv
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
