5. Vim hais tias kev sib txuas lus yog digital es tsis yog analogue, ntau yam khoom siv yuav tau txais qhov zoo tib yam dimming qhov tseem ceeb, uas ua rau muaj qhov zoo sib xws thiab raug dimming kev ua tau zoo.
6. Txhua yam khoom siv hauv lub cev muaj qhov chaw nyob tshwj xeeb, muab ntau yam kev xaiv rau kev tswj hwm tus kheej.
DALI thiab 1-10V sib piv li cas?
DALI tau tsim rau thiab los ntawm kev lag luam teeb pom kev zoo, zoo li 1-10V. Teeb pom kev zoo tswj qhov chaw nrog DALI thiab 1-10V interfaces, xws li LED tsav tsheb thiab sensors, yog muab los ntawm ntau tus neeg muag khoom. Tab sis nws tsuas yog zoo ib yam li muaj.
Muaj qee qhov sib txawv tseem ceeb ntawm DALI thiab 1-10V:
DALI tuaj yeem hais txog. Qhov no ua rau txoj hauv kev rau ntau yam muaj txiaj ntsig nrog rau kev sib koom ua ke, qhov chaw teeb tsa, thiab kev tswj kom muaj zog, uas tso cai rau cov khoom xws li hloov cov sensors thiab cov keyboards tswj cov teeb pom kev zoo hauv cov tshuaj tiv thaiv rau kev hloov hauv chaw ua haujlwm layout.
Tsis yog analogue, tab sis digital, yog DALI. Yog li DALI tuaj yeem muab kev tswj lub teeb pom kev deb dua thiab txhim khu kev qha dimming.
Txij li DALI yog tus qauv, piv txwv li, qhov nkhaus dimming tau teev tseg, tso cai rau cov chaw tsim khoom-rau-tus neeg tsim khoom sib raug zoo ntawm cov khoom siv. Kev siv ntau lub tuam txhab tsav tsheb ntawm tib txoj kev dimming yuav ua rau qee qhov tshwm sim tsis tau tshwm sim txij li 1-10V dimming nkhaus yeej tsis tau txhais.
Tsuas yog qhov yooj yim dimming thiab switching on/off yog tswj ntawm 1-10V. DALI muaj peev xwm tswj tau cov xim, hloov xim, kuaj thiab muab cov lus tawm tswv yim rau lub teeb thaum muaj xwm txheej ceev, tsim cov xwm txheej nyuaj, thiab ua ntau lwm yam teeb pom kev zoo.
Kuv puas tuaj yeem siv DALI cov khoom lag luam nrog lwm yam khoom DALI?
Vim tias tus qauv tau txwv tsis pub dhau, muaj qee qhov teeb meem sib raug zoo nrog thawj qhov kev rov ua dua ntawm DALI. Tus nqi ntawm cov lus qhia uas tuaj yeem raug xa mus thiab kev sib tsoo kev sib tsoo yog ob qho tib si nruj heev los ntawm qhov tseeb tias txhua DALI cov ntaub ntawv thav duab tsuas muaj 16 khoom (8 khoom rau qhov chaw nyob thiab 8 khoom rau cov lus txib). Yog li ntawd, ib tug xov tooj ntawm manufacturers sim ua kom nws muaj peev xwm los ntawm kev ntxiv lawv tus kheej nta, uas ua rau tej yam incompatibilities.
Qhov no tau hais nrog kev taw qhia ntawm DALI-2.
DALI-2 muaj qhov dav dav dua li qhov qub thiab ntau yam uas tsis suav nrog hauv nws. Raws li qhov tshwm sim, cov kev hloov kho uas ntau lub tuam txhab ua rau DALI tsis tsim nyog lawm. Thov xa mus rau nqe lus hauv qab no hauv "DALI ua haujlwm li cas" rau kev piav qhia ntxaws ntxiv ntawm DALI-2 tsim.
Lub Digital Illumination Interface Alliance (DiiA), tus tswv ntawm DALI-2 cim, tau tso cov kev txwv nruj rau nws kev siv. Qhov tseem ceeb tshaj plaws ntawm lawv yog tias tsis muaj cov khoom lag luam yuav muaj DALI-2 cim tshwj tsis yog tias nws tau dhau los ntawm cov txheej txheem ntawv pov thawj cais kom ntseeg tau tias nws ua tau raws li IEC62386.
DALI-2 tso cai, nrog qee qhov kev txwv, kev siv ob qho tib si DALI-2 thiab DALI cov khoom hauv ib qho kev teeb tsa. Qhov no tseem ceeb txhais tau hais tias DALI LED tsav tsheb - piv txwv tseem ceeb - tuaj yeem siv hauv DALI-2 kev npaj.
KNX, LON, thiab BACnet piv rau DALI li cas?
Lub tsev tswj kev cai xws li KNX, LON, thiab BACnet yog tsim los rau kev sib koom ua ke thiab tswj ntau lub tshuab thiab cov khoom siv sib kis thoob plaws lub tsev. Lawv tsis tuaj yeem siv raws li kev tswj hwm teeb pom kev zoo vim tias yuav luag tsis muaj cov tsav tsheb LED ntawm lub khw uas tuaj yeem ua kom muaj kev sib txuas ncaj qha rau cov kev cai no (txawm tias muaj tsawg tsawg tus tsav tsheb LED muaj nrog KNX interface).
Lub DALI-2 cov lus txib, ntawm qhov tod tes, muaj ntau cov lus qhia teeb pom kev zoo txij li DALI thiab DALI-2 tau tsim feem ntau rau kev tswj teeb pom kev zoo. Cov no muaj xws li dimming, xim-hloov, scene-teeb, kuaj thaum muaj xwm ceev thiab tawm tswv yim, thiab circadian teeb pom kev zoo commands thiab functions. Tshwj xeeb tshaj yog cov tsav tsheb LED, muaj ntau yam ntawm cov teeb pom kev zoo tswj cov khoom muaj kev sib txuas ncaj qha DALI.
Hauv ntau qhov kev siv, kev tswj hwm lub tsev (BMS) yuav ntiav KNX, LON, BACnet thiab cov txheej txheem cuam tshuam los tswj tag nrho lub tsev (kev koom ua ke HVAC, kev ruaj ntseg, kev nkag mus, tswj, elevators, thiab lwm yam), qhov DALI yuav siv los tswj cov khoom siv. teeb. Thaum xav tau, lub rooj vag yuav tso cai rau kev sib txuas lus ntawm BMS thiab lub teeb pom kev zoo yog li, piv txwv li, yog tias tus neeg tuaj yeem raug ntes los ntawm kev ruaj ntseg, tag nrho cov teeb pom kev hauv tsev tuaj yeem qhib los ntawm DALI.
DALI ua haujlwm li cas?
Lub hauv paus ntsiab lus ntawm DALI yog lub tsheb npav, uas yog tsim los ntawm ob lub xov hlau siv los xa cov cim tswj digital los ntawm cov sensors thiab lwm yam khoom siv nkag mus rau hauv daim ntawv thov. Txhawm rau tsim cov teeb liab tawm rau cov khoom siv xws li LED tsav tsheb, daim ntawv thov tswj hwm siv cov cai uas nws tau tsim nrog.
