1. UL 217 9th Edition yog dab tsi?
UL 217 yog Tebchaws Meskas tus qauv rau cov khoom siv ntes pa luam yeeb, siv dav hauv cov tsev nyob thiab cov tsev lag luam kom ntseeg tau tias cov tswb pa luam yeeb teb sai rau kev phom sij hluav taws thaum txo cov tswb cuav. Piv rau cov qauv dhau los, covTsab thib 9qhia txog cov kev cai ua haujlwm nruj dua, tshwj xeeb tshaj yog tsom mus rau kev ntes ntau hom pa luam yeeb nrog qhov tseeb dua.
2. Muaj dab tsi tshiab hauv UL 217 9th Edition?
Cov Kev Hloov Kho Tseem Ceeb Muaj Xws Li:
Kev Ntsuas Rau Ntau Hom Hluav Taws:
Hluav Taws Kub Hnyiab(Pas Dawb): Tsim los ntawm cov khoom siv uas kub qeeb xws li rooj tog lossis ntaub ntawm qhov kub qis.
Hluav Taws Kub Ceev(Pas Dub): Tsim los ntawm kev kub hnyiab ntawm cov khoom siv xws li yas, roj, lossis roj hmab.
Kev Ntsuas Kev Ua Noj Ua Haus:
Tus qauv tshiab yuav tsum tau cov tswb ceeb toom pa luam yeeb kom paub qhov txawv ntawm cov pa luam yeeb ua noj txhua hnub thiab cov pa luam yeeb hluav taws tiag tiag, kom txo tau qhov ceeb toom cuav.
Lub Sijhawm Teb Rov Qab Nruj Dua:
Cov tswb ceeb toom pa luam yeeb yuav tsum teb rau lub sijhawm tshwj xeeb thaum ntxov ntawm hluav taws, kom ntseeg tau tias cov lus ceeb toom sai dua thiab txhim khu kev qha dua.
Kev Ntsuas Kev Ruaj Ntseg Ib puag ncig:
Kev ua tau zoo yuav tsum nyob ruaj khov nyob rau hauv ntau yam xwm txheej ib puag ncig, suav nrog qhov kub thiab txias, av noo, thiab hmoov av.
3. Peb Qhov Zoo ntawm Cov Khoom: Dual Infrared Emitters rau Kev Tshawb Pom Pa Luam Yeeb
Yuav kom ua tau raws li qhov xav tau ntawm UL 217 9th Edition, peb lub tshuab ntes pa luam yeeb muaj cov yam ntxwvob lub teeb infrared, ib qho thev naus laus zis tseem ceeb uas ua rau kev ua haujlwm nrhiav tau zoo dua raupa luam yeeb dubthiabpa luam yeeb dawbNov yog li cas cov thev naus laus zis no pab tau rau kev ua raws li txoj cai:
Kev rhiab heev dua:
Cov khoom siv hluav taws xob infrared ob lub, ua ke nrog lub photodetector, txhim kho lub peev xwm los ntes cov pa luam yeeb ntawm ntau qhov ntau thiab tsawg.
Qhov no ua kom ntseeg tau tias muaj kev tshawb pom zoocov khoom me me(pa luam yeeb dub los ntawm cov hluav taws kub hnyiab) thiabcov khoom loj(pa luam yeeb dawb los ntawm cov hluav taws kub hnyiab), ua tau raws li qhov yuav tsum tau ua rau ntau hom hluav taws.
Txo Cov Tswb Ceeb Toom Cuav:
Lub kaw lus infrared ob chav ua rau kev kuaj pom tseeb dua los ntawm kev paub qhov txawv ntawm cov pa luam yeeb uas muaj feem cuam tshuam nrog hluav taws thiab cov teeb meem uas tsis yog hluav taws, xws li cov pa luam yeeb ua noj.
Lub Sijhawm Teb Sai Dua:
Nrog ntau lub kaum sab xis infrared detection, pa luam yeeb raug txheeb xyuas sai dua thaum nkag mus rau hauv chav kuaj, txhim kho lub sijhawm teb thiab ua tau raws li tus qauv xav tau lub sijhawm.
Kev Hloov Kho Ib Puag Ncig Zoo Dua:
Los ntawm kev ua kom zoo dua qhov kev tshawb pom qhov muag pom, lub kaw lus infrared ob chav txo qhov cuam tshuam los ntawm qhov kub thiab txias, av noo, lossis hmoov av, ua kom muaj kev ua haujlwm ruaj khov hauv qab cov xwm txheej nyuaj.
4. Peb Cov Khoom Ua Raws Li UL 217 Tsab Ntawv Thib 9 Li Cas
Peb lub tshuab ntes pa luam yeeb tau hloov kho dua tshiab kom ua raws li cov kev cai tshiab ntawm UL 217 9th Edition:
Cov Txuj Ci Tseem Ceeb:Tus qauv tsim infrared ob chav ua rau pom tseeb ntawm cov pa luam yeeb dub thiab dawb thaum ua tau raws li cov kev cai txo qis kev cuam tshuam.
Kev Ntsuas Kev Ua Tau Zoo: Peb cov khoom ua tau zoo heev hauv hluav taws kub hnyiab, hluav taws kub hnyiab, thiab cov pa luam yeeb ua noj, nrog lub sijhawm teb sai dua thiab muaj kev rhiab heev dua.
Kev Txheeb Xyuas Kev Ntseeg Tau: Kev sim ua qauv ib puag ncig dav dav ua kom muaj kev ruaj khov zoo dua thiab kev tiv thaiv kev cuam tshuam.
5. Xaus Lus: Kev Txhim Kho Kev Ntseeg Siab Los Ntawm Kev Txhim Kho Tshuab
Qhov kev qhia txog UL 217 9th Edition teeb tsa cov qauv siab dua rau kev ua haujlwm ntawm lub tshuab ntes pa luam yeeb. Pebdual infrared emitter thev naus laus zis tsis yog tsuas yog ua tau raws li cov qauv tshiab no xwb tab sis kuj ua tau zoo heev hauv kev rhiab heev ntawm kev ntes, teb sai dua, thiab txo cov lus ceeb toom cuav. Cov thev naus laus zis tshiab no ua kom peb cov khoom muab kev tiv thaiv txhim khu kev qha hauv cov xwm txheej hluav taws tiag tiag, pab cov neeg siv khoom dhau qhov kev xeem ntawv pov thawj nrog kev ntseeg siab.
