Cov nqi tseem ceeb rau kev txhim kho LED zaub suav nrog tus nqi ntawm lub vijtsam, tus nqi ntawm kev tswj hwm, tus nqi ntawm lub computer thiab cov khoom siv suab, thiab cov nqi tsim kho. Tus nqi tsim kho tuaj yeem muab faib ntxiv rau hauv qhov chaw xws li kev tsim vaj tsev engineering, steel qauv moj khaum, kho kom zoo nkauj sab nrauv, thiab lub zog thiab tsis muaj zog tam sim no. Nov yog cov lus qhia ntxaws:
Screen nqi
Cov nqi tshuaj ntsuam yog muab los ntawm LED zaub manufacturers thiab feem ntau xam los ntawm qhov loj ntawm tus ncej, module lossis square. Qhov no yog cov khoom siv ncaj qha rau kev txhim kho LED cov lus qhia. Tus nqi ntawm LED zaub ntawm txawv specifications, qauv thiab hom txawv ho. Piv txwv li, cov ntxaij vab tshaus nrog me me pixel qhov sib nrug thiab cov duab zoo dua feem ntau muaj tus nqi siab dua.
Tus nqi tswj qhov system
Lub kaw lus tswj thiab qhov screen yog muag ua ke. Tus nqi tshwj xeeb nyob ntawm qhov loj ntawm lub vijtsam zaub. Lub kaw lus tswj yog ib feem tseem ceeb ntawm LED zaub rau kev pom cov ntsiab lus ib txwm muaj. Nws yog lub luag haujlwm rau kev txais thiab ua cov cim, thiab ua kom pom cov duab, yeeb yaj kiab thiab lwm yam ntsiab lus ntawm qhov screen. Cov ntxaij vab tshaus loj dua yuav tsum muaj lub zog ntau dua thiab kev tswj xyuas kom ruaj khov thiab zoo ntawm cov zaub, thiab yog li tus nqi kuj tseem siab dua.
Tus nqi ntawm cov khoom siv computer audio
Thaum tag nrho - xim LED zaub raug ua si, lub computer yuav tsum synchronously tso saib cov ntsiab lus thiab suab paj nruag. Qhov no suav nrog cov nqi ntawm lub computer thiab cov khoom siv suab. Yog tias ib zaug -xim thiab ob- xim cov ntaub ntawv raug xa los ntawm USB tsav, tsuas yog lub khoos phis tawj yuav tsum tau kho cov ntaub ntawv. Txawm li cas los xij, tag nrho - xim zaub feem ntau xav tau kev ua haujlwm hauv computer muaj zog dua los tswj cov duab nyuaj thiab cov ntaub ntawv video. Nyob rau tib lub sijhawm, kom ua tiav lub suab zoo, cov khoom siv suab nrov yuav tsum tau nruab, uas yuav ua rau tus nqi nce ntxiv.
Tus nqi tsim kho
Civil Engineering: Qhov no suav nrog kev khawb av thiab rov ua dua, pob zeb, steel tuav, thiab lwm yam khoom siv, nrog rau cov nqi siv tshuab thiab kev ua haujlwm. Cov lus hais yog nyob ntawm qhov ntim ntawm lub ntiaj teb ua haujlwm thiab pob zeb (hauv yuan ib cubic meter), qhov hnyav ntawm steel tuav (hauv yuan ib tuj), thiab tus nqi zog (hauv yuan ib tus neeg-hnub). Feem ntau, qhov kev ntsuas tuaj yeem sib npaug raws li qhov ntim ntawm cov pob zeb ua kom muaj zog, nrog rau qhov ntsuas qhov ntsuas yog 1000 - 1500 yuan. Qhov ntim ntawm lub hauv paus kev tsim vaj tsev engineering feem ntau yog kwv yees li ntawm thaj tsam ntawm lub cev sab saud. Piv txwv li, ib lub hauv paus ntawm 40 square metres muaj qhov ntim ntawm 40 cubic meters. Txawm li cas los xij, qhov tsis muaj tseeb yuav tsum tau tsim los ntawm lub koom haum tsim kev tshaj lij.
Steel qauv ncej: Tus nqi muaj xws li tus nqi ntawm cov hlau, tus nqi ntawm cov hlau reprocessing, tus nqi ntawm vuam zog thiab cov khoom pab. Cov hlau thiab cov khoom siv reprocessing yog hais los ntawm qhov hnyav (yuan / ton), thiab kev ua haujlwm vuam tau hais los ntawm hnub (yuan / hnub rau ib tus neeg). Feem ntau, qhov kev ntsuas tuaj yeem sib koom ua ke raws li qhov ntsuas qhov hnyav ntawm cov hlau. Hlau feem ntau raug nqi ntawm 5500 - 7000 yuan / ton (hloov raws li cov nqi lag luam), ntxiv rau 1000 - 1500 yuan / ton (hloov raws li kev tshaj tawm - txoj kev ua), vuam ua haujlwm feem ntau yog 2000 - 3500 yuan / ton, cov ntaub ntawv pabcuam yog kwv yees li 500 yuan / ton. Yog li ntawd, tus nqi tsim kho steel dav dav yog 9000 - 11000 yuan / tuj (tsis suav nrog rov ua dua). Hauv cov phiaj xwm LED pom, qhov dav dav dav tuaj yeem kwv yees ntawm 0.15T / m2. Yog tias siv cov kab teeb tsa, cov kab yuav tsum yog 0.4t / m, thiab ob kab yuav tsum tau muab faib ua ob npaug.
Qhov project kho kom zoo nkauj sab nrauv: Tus nqi muaj xws li cov khoom siv kho kom zoo nkauj, kho kom zoo nkauj tus nqi zog thiab cov khoom siv pabcuam. Cov khoom siv kho kom zoo nkauj thiab cov khoom siv pabcuam tau hais los ntawm cheeb tsam (yuan / square meter), thiab kev kho kom zoo nkauj yog hais los ntawm cov hnub (yuan / tus neeg-hnub). Feem ntau, qhov kev ntsuas tuaj yeem raug teeb tsa raws li thaj tsam kwv yees ntawm cov khoom siv kho kom zoo nkauj (yuan / square meter). Rau txhuas- yas board (ob -sided) kho kom zoo nkauj, feem ntau yog 450 - 650 yuan/square meter. LED zaub screen zoo li hexahedron. Tsuas yog xam tag nrho nws qhov chaw saum npoo av, rho tawm thaj chaw tso saib, thiab ntxiv 15% kev ua haujlwm poob kom tau txais thaj tsam kawg.
Fais fab thiab tsis muaj zog tam sim no thaiv qhov project: Tus nqi sib xyaw suav nrog cov nqi rau cables, conduits, conduit installation, thiab xaim zog. Cables, conduits, thiab lawv cov installation yog hais los ntawm qhov ntev (yuan / meter), thiab xaim kev ua haujlwm yog hais los ntawm tus neeg-hnub (yuan / neeg-hnub). Feem ntau, qhov kev ntsuam xyuas tuaj yeem suav tau raws li qhov ntev ntawm cov xaim. Rau cov cables tsis muaj zog tam sim no, 8-cov tub ntxhais network cables feem ntau yog 4 yuan / meter, shielded saj zawg zog cables feem ntau yog 4 yuan / meter, thiab optical fibers feem ntau yog 8 yuan / meter. Rau txhua qhov kawg ntawm cov khoom siv kho qhov muag, tus nqi ntawm lwm cov ntaub ntawv (welding, tail fibers, thiab lwm yam) yuav tsum tau nce 2,000 yuan. Muaj ntau yam kev qhia tshwj xeeb rau cov fais fab cables, thiab cov nqi lag luam hloov pauv tau zoo heev. Rau cov kab loj-ntev, nws raug nquahu kom cov neeg siv khoom nteg lawv hauv qhov chaw ua ntej.
