A tswj relay yog ib qho hluav taws xob tivthaiv uas qhib lossis kaw qhov hloov pauv txhawm rau tso cai rau tam sim no ntws los ntawm kev coj tus coil, nrog lub kauj tsis tuaj yeem nkag mus rau hauv kev sib cuag nrog tus hloov. Tswj relays yog cov khoom siv electromagnetic feem ntau tswj lub zog khiav incircuits.
Kuj nug, ua li cas relays ua haujlwm?
Yuav ua li cas relays ua haujlwm
- Lub input Circuit Court (xiav lub voj voog) raug kaw thiab tsis muaj cov dej ntws los ntawm nws kom txog rau thaum ib yam dab tsi (xws li lub sensor lossis lub kaw lus) tig rau nws.
- Thaum ib tug me me tam sim no ntws nyob rau hauv lub input circuit, nws activates lub electromagnet (pom ntawm no raws li ib tug maub xiav kauj), uas generates magnetic teb nyob ib ncig ntawm nws.
Ib yam li ntawd, Relay yog dab tsi thiab nws hom? Lub Xeev Relays Cov no yog txawv hom :rov relay ua ke SSR, transformer coupled SSR, yees duab-coupled SSR, thiab hais txog. Solid State Relays.
Ib yam li ntawd, tib neeg nug, vim li cas siv relay?
A relay yog electromagnetic hloov uas yog siv kom qhib thiab kaw lub voj voog los ntawm lub zog qis, lossis qhov twg ntau lub circuits yuav tsum tau tswj los ntawm ib lub teeb liab. Peb paub tias feem ntau ntawm high-end industrial application deviceshave relays rau lawv txoj haujlwm zoo.
Tsis muaj NC relay ua haujlwm li cas?
Nquag kaw ( NC ) tiv tauj disconnect lub Circuit Court thaum lub relay yog qhib; lub Circuit Court yog txuas thaum lub relay yog inactive. SPST- TSIS MUAJ (Single-Pole Ib-throw, Nquag-Qhib) relays muaj ib daim Form A hu los yog hu rau. Cov no muaj ob lub terminals uas ua tau tau kev cob cog rua ordisconnected.

Qhov twg hauv qab no yog suav tias yog kev tswj hwm kev ua haujlwm ntawm kev tswj hwm database DBMS)?
Databases uas nqa lawv cov ntaub ntawv nyob rau hauv daim ntawv ntawm cov ntxhuav thiab uas sawv cev rau kev sib raug zoo siv txawv teb chaws yuam sij yog hu ua discrete databases. Kev tswj hwm kev ua haujlwm ntawm kev tswj hwm qhov system (DBMS) suav nrog thaub qab cov ntaub ntawv database
Dab tsi yog vSphere nrog Kev Tswj Xyuas Kev Tswj Xyuas Kev Lag Luam Ntxiv?
VMware vSphere® nrog Kev Tswj Xyuas Kev Ua Haujlwm ™ muaj kev ntseeg siab tshaj plaws virtualization platform nrog kev ua haujlwm tseem ceeb hauv kev saib xyuas kev ua tau zoo thiab kev tswj hwm kev muaj peev xwm
Kev tswj hwm kev tswj hwm hauv kev ruaj ntseg ntaub ntawv yog dab tsi?
Kev tswj hwm kev nyab xeeb (tseem hu ua cov txheej txheem tswj hwm) feem ntau yog cov txheej txheem thiab cov cai uas tau muab tso rau hauv qhov chaw los txheeb xyuas thiab qhia cov neeg ua haujlwm hauv kev cuam tshuam nrog cov koom haum cov ntaub ntawv rhiab
Lub luag haujlwm ntawm kev ua haujlwm yog dab tsi ua tus tswj hwm kev pabcuam?
Lub Operating System raws li ib tug Resource Manager. Internally Operating System ua tus saib xyuas cov peev txheej ntawm lub khoos phis tawj xws li processor, nco, cov ntaub ntawv, thiab I / O ntaus ntawv. Hauv lub luag haujlwm no, lub operating system khaws cov xwm txheej ntawm txhua qhov peev txheej, thiab txiav txim siab leej twg tau txais cov peev txheej, ntev npaum li cas thiab thaum twg
Qhov kev tswj hwm twg suav nrog kev tswj hwm lub cev thiab kev tswj hwm?
Piv txwv suav nrog kev tswj lub cev xws li laj kab, xauv, thiab lub tswb nrov; kev tswj xyuas xws li antivirus software, firewalls, thiab IPSs; thiab kev tswj hwm kev tswj hwm xws li kev sib cais ntawm lub luag haujlwm, kev faib cov ntaub ntawv, thiab kev tshuaj xyuas
