Pali osiyanasiyana kwambiriDALI idathandizira zinthu zowongolera kuyatsakupezeka kuchokera kwa opanga onse otsogola ndipo tsopano akudziwika kuti ndi muyezo wapadziko lonse wowongolera kuyatsa.

Zofunikira za DALI:

• Ndi protocol yotseguka - wopanga aliyense angagwiritse ntchito.
• Ndi kugwirizana kwa DALI-2 pakati pa opanga kumatsimikiziridwa ndi njira zovomerezeka zovomerezeka.
• Kuyika ndi kosavuta.Mphamvu ndi zingwe zowongolera zitha kuikidwa palimodzi ndipo palibe chitetezo chofunikira.
• Ma waya topology amatha kukhala mu mawonekedwe a nyenyezi (hub & analankhula), mtengo kapena mzere, kapena kuphatikiza kulikonse kwa izi.
• Kuyankhulana ndi digito, osati analogi, kotero kuti mdima womwewo ukhoza kulandiridwa ndi zipangizo zingapo zomwe zimapangitsa kuti ntchito ikhale yokhazikika komanso yolondola.
• Zida zonse zili ndi adilesi yawoyawoyake mudongosolo ndikutsegula mwayi wambiri wowongolera wosinthika.

KODI DALI IKUFANANA BWANJI NDI 1-10V?

DALI, ngati 1-10V, idapangidwira komanso ndi makampani opanga zowunikira.Zida zowongolera zowunikira, monga madalaivala a LED ndi masensa, zimapezeka kuchokera kwa opanga omwe ali ndi mawonekedwe a DALI ndi 1-10V.Komabe, ndi pamene kufanana kumathera.

Kusiyana kwakukulu pakati pa DALI ndi 1-10V ndi:

• DALI ndiyotheka.Izi zimatsegula njira ya zinthu zambiri zamtengo wapatali monga magulu, kuyika zochitika ndi kulamulira kwamphamvu, monga kusintha masensa ndi ma switches omwe amawongolera kuwala kogwirizana ndi kusintha kwa ofesi.
• DALI ndi digito, osati analogi.Izi zikutanthauza kuti DALI ikhoza kupereka kuwongolera kolondola kwambiri komanso kuwunikira kosasintha.
• DALI ndi muyezo, kotero, mwachitsanzo, dimming curve ndi yokhazikika kutanthauza kuti zida ndizogwirizana pakati pa opanga.1-10V dimming curve sinakhalepo yokhazikika, kotero kugwiritsa ntchito mitundu yosiyanasiyana ya madalaivala panjira yocheperako kungapangitse zotsatira zosagwirizana kwambiri.
• 1-10V imatha kuwongolera kuyatsa / kuzimitsa ndi dimming yosavuta.DALI imatha kuyang'anira kuwongolera mitundu, kusintha kwamitundu, kuyesa kuyatsa kwadzidzidzi ndi mayankho, kuyika zochitika zovuta ndi ntchito zina zambiri zokhudzana ndi kuyatsa.

NDI ONSEMalingaliro a kampani DALI PRODUCTSZOGWIRIZANA NDI MTIMA?

Ndi mtundu woyambirira wa DALI, panali zovuta zina chifukwa mafotokozedwe ake anali ochepa.Dongosolo lililonse la data la DALI linali ma 16-bits (8-bits pa adilesi ndi 8-bits kwa lamulo), kotero kuchuluka kwa malamulo komwe kunalipo kunali kochepa kwambiri ndipo panalibe kuzindikira kugunda.Zotsatira zake, opanga angapo adayesa kukulitsa luso lake popanga zowonjezera zawo, zomwe zidapangitsa kuti zikhale zosagwirizana.

Ndi kubwera kwa DALI-2 izi zagonjetsedwa.

• DALI-2 ndiyofuna kwambiri kukula kwake ndipo ili ndi zinthu zambiri zomwe sizinali mu mtundu woyambirira.Chotsatira cha izi ndikuti zowonjezera zomwe opanga pawokha adapanga ku DALI sizoyeneranso.Kuti mumve zambiri za zomangamanga za DALI-2, chonde pitani ku "Momwe DALI imagwira ntchito", pansipa.
• Chizindikiro cha DALI-2 ndi cha DiiA (Digital Illumination Interface Alliance) ndipo aphatikiza mikhalidwe yokhwima pakugwiritsa ntchito kwake.Chachikulu pakati pa izi ndi chakuti palibe chogulitsa chomwe chinganyamule chizindikiro cha DALI-2 pokhapokha ngati chidachitapo kanthu paziphaso zodziyimira pawokha kuti muwone ngati ikutsatira IEC62386.

DALI-2 imalola kugwiritsa ntchito zigawo zonse za DALI-2 ndi DALI pakuyika kamodzi, malinga ndi zoletsa zina.M'malo mwake, izi zikutanthauza kuti madalaivala a DALI LED (monga chitsanzo chachikulu) angagwiritsidwe ntchito pakuyika kwa DALI-2.

KODI DALI AMAGWIRA BWANJI?

Pakatikati pa DALI ndi basi - mawaya awiri omwe amanyamula zizindikiro zowongolera digito kuchokera ku zida zolowera (monga masensa), kupita kwa woyang'anira ntchito.Woyang'anira ntchito amagwiritsa ntchito malamulo omwe adakonzedwa kuti apange ma siginecha otuluka ku zida monga madalaivala a LED.

• Bus Power Supply Unit (PSU).Chigawo ichi nthawi zonse chimafunika.Imasunga mphamvu ya basi pamlingo wofunikira.
• Zida za LED.Zowunikira zonse pakuyika kwa DALI zimafuna dalaivala wa DALI.Dalaivala wa DALI akhoza kuvomereza malamulo a DALI mwachindunji kuchokera ku basi ya DALI ndikuyankha moyenera.Madalaivala amatha kukhala zida za DALI kapena DALI-2, koma ngati sali DALI-2 sadzakhala ndi zina zatsopano zomwe zatulutsidwa ndi mtundu waposachedwa.
• Zipangizo zolowetsa - masensa, masiwichi etc. Izi zimalumikizana ndi wowongolera ntchito pogwiritsa ntchito mafelemu a data 24-bit.Salankhulana mwachindunji ndi zida zowongolera.
• Zochitika.Nthawi zambiri, chipangizo monga sensa chimakhala ndi zida zingapo zosiyana mkati mwake.Mwachitsanzo, masensa nthawi zambiri amakhala ndi chojambulira chakuyenda (PIR), chowunikira chowunikira komanso cholandila chofiira cha infra-red.Izi zimatchedwa zochitika - chipangizo chimodzi chimakhala ndi zochitika zitatu.Ndi DALI-2 chitsanzo chilichonse chikhoza kukhala cha gulu lolamulira ndipo aliyense akhoza kuwongolera kuti aziwongolera magulu osiyanasiyana owunikira.
• Zida zowongolera - zowongolera ntchito.Woyang'anira ntchito ndi "ubongo" wa dongosolo.Imalandira mauthenga a 24-bit kuchokera ku masensa (ndi zina) ndikupereka malamulo a 16-bit ku gear yolamulira.Woyang'anira ntchito amayang'aniranso kuchuluka kwa data pabasi ya DALI, kuyang'ana kugundana ndikuperekanso malamulo ngati pakufunika.
