Txheej txheem cej luam:

SuavLub teb chaws yuav tsum tus qauv GB 4943.1-2022, Audio/Cov khoom siv yees duab, xov xwm thiab kev sib txuas lus Technology Part 1: Kev ruaj ntseg yuav tsum, tau tshaj tawm thaum Lub Xya Hli 19. Tus qauv hais txog tus qauv thoob ntiaj teb IEC 62368-1: 2018, muaj ob qhov kev txhim kho tseem ceeb:on ntawm ib sab, cov peev txheej ntawm daim ntawv thov tau nthuav dav ntxiv, cov qauv tshiab ntawm tus qauv sib koom ua ke cov qauv tseem ceeb hauv tebchaws GB 4943.1-2011Cov Khoom Siv Technology Kev Ruaj Ntseg Ntu 1: Cov Lus Qhia dav davthiab GB 8898-2011Suab, yees duab thiab zoo sib xws Electronic Equipment Security Requirements, npogtag nrho cov khoom ntawm lub suab, video, cov ntaub ntawv thiab kev sib txuas lus cuab yeej cuab tam;on lwm tus tes,muajtechnically optimizehauvthiab upgrade. Tnws tshiab version ntawm tus qauvtsa covtswvyim ntawm kev ruaj ntseg engineering, thovskev faib hluav taws xob,thiabtakes kev txiav txim siab ntawm Hauv qab no rau 6 hom kev txaus ntshai:kev raug mob los ntawm hluav taws xob, hluav taws xob los ntawm hluav taws xob, kev raug mob los ntawm cov khoom tsis zoo, kev raug mob los ntawm kev siv tshuab, thermal burns, suab thiab lub teeb hluav taws xob, thiab muab tso rau hauv cov kev xav tau kev nyab xeeb thiab kev sim.

Qhov txawv ntawm qhov qub version:

• Daim ntawv thovthaj tsamof obtxheemsyog txawv. Covthaj tsam ntawmtshiab GB 4943 lub teb chaws tus qauv yuav ua ke yav dhau los version ntawm GB 4943.1-2011 thiab GB 8898-2011, npogpeb pawg ntawmkhoom siv, cov khoom siv audio thiab video, cov khoom siv thev naus laus zis, cov khoom siv thev naus laus zis sib txuas lus, uas peb feem ntau hais tias "cov khoom siv hluav taws xob".
• Energy qhov kev faib tawm thiab kev faib cov neeg ua haujlwmtau npaj. Qhov tshiabtxheemwb 4943cais cov khoom siv hluav taws xob. Muaj peb theem ntawm kev puas tsuaj uas lub zog tuaj yeem ua rau:"Tsis Muaj Mob, tab sis koj tuaj yeem hnov ​​​​nws", "Hmoov, tab sis tsis ua rau raug mob" thiab "Ua rau raug mob".Tus qauv tseem faib cov neeg ua haujlwm sib raug rau hauv peb pawg. Ntau pawg ntawm cov neeg ua haujlwm muaj kev paub txog kev phom sij sib txawv thiab muaj peev xwm sib txawv ntawm lawv, yog li kev ntsuas kev nyab xeeb sib txawv yog siv rau cov neeg ua haujlwm sib txawv thiab cov khoom siv hluav taws xob sib txawv. Kev tiv thaiv kev nyab xeeb ob npaug yog siv rau cov khoom uas yuav ua rau raug mob hnyav rau cov neeg ua haujlwm yam tsis muaj kev paub tshwj xeeb, thaum tib yam kev phom sij rau cov kws tshaj lij thiab cov kws tshaj lij tsuas yog siv cov kev tiv thaiv kev nyab xeeb zoo tib yam.

Qhov sib txawv ntawm IEC 62368:

• Raws li cov xwm txheej tshwj xeeb ntawm cov khoom siv hluav taws xob thiab kev faib tawm hauv Suav teb cov tsev, cov khoom siv hluav taws xob tsis tuaj yeem tso siab rau cov khoom siv tiv thaiv hauv lub tsev los muab kev tiv thaiv.. Tnws cov qauv tshiab hauv tebchaws GB 4943 xav tauskev txais yuav cov kev ntsuas kev nyab xeeb ntau dua, xav tau cov khoom siv hluav taws xob lawv tus kheej yuav tsum muaj cov khoom siv tiv thaiv overcurrent thiab tiv thaiv hauv av thiab cov teeb liab hauv av yuav tsum tau ntsuas kev cais tawm.
• Raws lipeb tshwj xeeb thaj chaw, muajkev sib txawv ntawm cov kev xav tau kev nyab xeeb. Piv txwv li, cov qauv thoob ntiaj teb feem ntau yog tsim rau thaj chawqis dua2000m saum toj no hiav txwv theem, thaum ze li ib feem peb ntawm Tuam Tshoj cov av yog siab tshaj 2000m saum toj no hiav txwv theem thiab muaj cov neeg coob nyob rau ntawd. Nyob ntawd cov huab cua yog thinner thiab ntau dua rau hluav taws xob tawg, uas ua rau hluav taws xob raug mob.Pab cov neeg nyob hauvthaj chaw siab siabtokev nyab xeeb siv cov khoom siv hluav taws xob, GB 4943 tshiab muaj qhov xav tau ntau dua ntawm cov rwb thaiv tsev cua hauv cov txheej txheem tsim thiab tsim cov khoom siv hluav taws xob.
• Raws li Tuam Tshoj txoj kev nyab xeeb,muajkev sib txawv ntawm cov kev xav tau kev nyab xeeb. Xav tias thaj tsam loj ntawm Tuam Tshoj yog huab cua sov, huab cua kub thiab av noo yuav txo tau cov ntaub ntawv rwb thaiv tsev, tus tshiab GB 4943 tag nrho xav txog.sqhov cuam tshuam ntawm no tropical kev nyab xeeb,thiab qhiacov kev sib raug zoo sib txawv los tiv thaiv kev nyab xeeb ntawm cov khoom siv hluav taws xob siv los ntawm cov neeg siv khoom hauv cov huab cua sov hauv Suav teb.

Cov ntsiab lus:

Lub teb chaws tus qauv tshiab GB 4943 yuav siv tag nrho cov nyiaj ntawm hluav taws xob poob siab, overheating, hluav taws kub, mechanical thiab lwm yam kev phom sij.thiab tom qab ntawdtxhim khosua tiavthiab systematickev tiv thaiv. Tus qauvtsis yog xwbsiv rau cov qauv thoob ntiaj teb los txiav txim siab txog kev nyab xeeb thoob ntiaj teb, tab sis kujxav txogTuam Tshoj qhov chaw siab tshaj plaws, huab cua sov thiab lwm yam hauv lub tebchaws tshwj xeebthiab txhim khukev nyab xeeb thiab kev tiv thaiv ntawm cov kev cai tshwj xeeb.
