Feem ntau cov kev sib tham nyob ib ncig ntawm LED zaub kev ntseeg tau tsom rau cov khoom zoo - lub neej teeb, tsav ICs, solder workmanship. Txawm li cas los xij hauv kev teeb tsa tiag tiag, qhov feem ntau yuav ua tsis tau yog tsis tshua muaj LEDs lawv tus kheej. Cov khoom siv hluav taws xob, cov khoom sib txuas, thiab cov ntawv txais daim npav muaj qhov ua tsis tau zoo tshaj plaws ntawm txhua lub cev, thiab txhua tus zaum hauv nruab nrab ntawm txoj kev teeb liab-lossis-lub zog. Qhov no yog vim li cas cov phiaj xwm kev tshaj lij tau qhia txog ob txheej ntawm kev rov ua dua tshiab: cov khoom siv hluav taws xob dual thiab cov ntawv txais nyiaj rov qab. Kab lus no piav qhia txog yuav ua li cas ob lub tswv yim ua haujlwm, lawv ua dab tsi thiab tsis tiv thaiv, thiab thaum tus nqi ntxiv yog tsim nyog.
Yog vim li cas Ib-Point Failures teeb meem nyob rau hauv LED zaub
Lub vijtsam LED tsis yog ib qho khoom siv - nws yog cov saw hlau ntawm kaum rau ntau txhiab tus qauv zoo ib yam, txhua tus nyob ntawm nws tus kheej lub zog thiab cov ntaub ntawv tawm tswv yim. Nyob rau hauv ib qho kev tsim qauv, poob ib lub hwj huam mov blanks tawm txhua lub txee nws pub, thiab poob daim npav txais ntawm lub taub hau ntawm cov ntaub ntawv voj yuav siv sij hawm tag nrho ntawm qhov screen tsaus. Rau lub studio tshaj tawm xov xwm, ib theem xauj tsev, lossis cov ntaub ntawv xov xwm tsheb, uas tsis yog qhov tsis pom kev xwb; nws yog downtime uas cuam tshuam qhov kev tshwm sim nyob lossis kev pabcuam pej xeem.
Yuav Ua Li Cas Dual Power Supplies Ua Haujlwm
Hauv kev teeb tsa hluav taws xob tsis sib xws, txhua lub txee yog pub los ntawm ob lub zog siv hluav taws xob sib luag. Raws li ib txwm muaj, ob chav sib faib cov khoom thauj, yog li txhua tus khiav ntawm kwv yees li ib nrab lub peev xwm - uas tseem txo qis kev ua haujlwm ntawm txhua chav tsev thiab txuas nws lub neej. Yog tias ib chav ua tsis tiav, chav tsev tseem muaj sia nyob tam sim ntawd nqa tag nrho cov khoom ntawm nws tus kheej, thiab lub vijtsam tseem pom tsis pom qhov hloov pauv. Vim tias cov khoom tsis ua tiav tuaj yeem hloov pauv ntawm lub nraub qaum (lossis pem hauv ntej) thaum lub sijhawm tu, qhov tsis ua haujlwm nws tus kheej dhau los ua cov khoom tu tsis yog thaum muaj xwm txheej ceev.
Muaj ob txoj hauv kev siv tau. Ua ntej, redundancy tiv thaivibkhoom tsis ua haujlwm, tsis yog ob qho tib si; lub system yog tsis ua hauj lwm-kev nyab xeeb, tsis ua hauj lwm-pov thawj. Qhov thib ob, chav tsev tseem muaj sia nyob yuav tsum raug ntsuas tiag tiag rau cov khoom thauj khoom tag nrho - qee qhov kev tsim peev nyiaj siv ob qho khoom siv tsis zoo uas nws qhov kev ntsuas sib xyaw ua ke tsis tshua muaj qhov siab tshaj plaws, uas muaj kev tiv thaiv me ntsis.
Yuav ua li cas thaub qab txais daim npav ua haujlwm
Redundancy ntawm qib tswj raws li tib lub logic. Txhua lub txee lossis cheeb tsam hauv cheeb tsam nqa ib daim npav txais thaub qab uas zaum tsis ua haujlwm thaum daim npav thawj ua haujlwm. Ob daim npav saib xyuas ib leeg, thiab yog tias daim npav thawj zaug tsis teb lossis pib ua cov khoom tsis raug, tswj kev hloov mus rau qhov thaub qab tau txais, feem ntau hauv ob peb thav ntawv. Nyob rau hauv lub system theem, dual fiber ntau los yog network loops ntawm lub video processor thiab thawj lub txee - feem ntau yog teem nyob rau hauv lub nplhaib topology - txhais tau hais tias cov zaub muaj peev xwm ciaj sia ib tug tawg cable los yog ib tug tuag chaw nres nkoj raws cov saw.
Backup cards yog tshwj xeeb tshaj yog muaj feem xyuam rau kev xauj tsev thiab theem cov ntxaij vab tshaus, qhov twg cables yog plugged thiab unplugged nyob rau hauv txhua txhua setup thiab voj breakage yog ib tug niaj hnub tshwm sim. Ntawm daim ntawv teev npe mus tas li lossis cov ntxaij vab tshaus vaj tse, qhov tsis ua haujlwm ntau dua yog lub zog sab, yog li kev siv hluav taws xob rov ua dua feem ntau xa ntau tus nqi ib duas.
Thaum twg Redundancy tsim nyog qhia?
Redundancy ntxiv tus nqi, qhov hnyav, thiab kev sib txuas me ntsis, yog li kev siv daim pam tsis yog ib txwm siv tau. Nws muab qhov tseeb tshaj plaws rov qab rau hauv peb qhov xwm txheej:
- Live tshaj tawm thiab cov chaw ua yeeb yam- Lub sijhawm tsaus ntuj ntawm lub koob yees duab tsis tuaj yeem rov qab tau, thiab cov teeb tsa xauj tsev twb ua rau muaj kev pheej hmoo siab tshaj plaws.
- Cov ntaub ntawv tseem ceeb rau pej xeem nthuav tawm- tsheb ciav hlau kos npe, chaw nres tsheb platforms, thiab chaw ua haujlwm ruaj ntseg, qhov chaw poob qis muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm.
- Qhia ntsia ntawm qhov siab- qhov twg txhua qhov kev mus ntsib yuav tsum muaj crane, cherry picker, lossis cov neeg ua haujlwm abseiling, thiab tus nqi ntawm ib qho kev kho thaum muaj xwm txheej ceev feem ntau tshaj tus nqi ntawm cov khoom siv rov qab.
Rau cov khoom lag luam sab hauv tsev lossis kev pheej hmoo qis dua kev tsim vaj tsev yam tsis tau teem sijhawm nyob, kev tsim khoom siv ib leeg nrog cov khoom siv zoo yuav yog qhov kev xaiv pheej yig dua - kev ntseeg siab yog tom qab ntawd tswj hwm los ntawm kev hloov pauv hloov.
Daim ntawv txheeb xyuas
Thaum ntsuam xyuas qhov kev daws teeb meem LED redundant, kos rau:
- Cov khoom siv hluav taws xob ntsuas raupuv txee load ntawm nws tus kheej, tsis yog nyob rau hauv parallel.
- Load-sharing thiab tsis siv neeg hloov-tshaj yam tsis muaj rebooting lub vijtsam.
- Lub sij hawm kom meej meej tsis ua tiav ntawm txoj kev tau txais daim npav (raug ntsuas hauv thav ntawv, tsis yog vib nas this).
- Kub-swappable units nkag tau los ntawm kev saib xyuas sab.
- Cov xwm txheej ceeb toom rau lub kaw lus tswj, yog li kuaj pom qhov tuag rov qab ua ntej nws tseem ceeb.
Xaus
Lub hwj chim rov qab thiab cov ntawv tau txais cov ntaub ntawv rov qab tsis ua rau LED zaub tsis muaj kev puas tsuaj - lawv nqaim qhov sib txawv ntawm cov khoom tsis ua haujlwm thiab pom qhov hluav taws xob. Qhia qhov twg downtime yog tiag tiag kim, thiab engineered nrog cov khoom ntsuas kom zoo es tsis yog ib chav tsev thib ob bolted hauv, redundancy hloov kev ntseeg tau los ntawm cov lus cog tseg rau hauv kev ntsuas tus cwj pwm ntawm lub system.
