Txij li thaum pib ntawm lub hnub nyoog kev lag luam, lub teeb qhov muag teev tau yog qhov kev tsim muaj txiaj ntsig tshaj plaws ntawm txhua lub sijhawm.Txhawm rau kom muaj lub teeb pom kev tas li uas tsis yog hluav taws uas yuav khiav ntawm hluav taws xob yog qhov loj heev rau kev loj hlob ntawm noob neej.Muaj keeb kwm ntev los ntawm qhov peb tau mus rau qhov chaw peb tam sim no hais txog hluav taws xob thiab teeb.

Kev tsim hluav taws xob, roj teeb thiab hluav taws xob tam sim no yog ib qho txiaj ntsig zoo rau noob neej.Los ntawm cov tshuab siv hluav taws xob rau lub foob pob hluav taws rau lub hom phiaj lub hli, peb ua tiav txhua qhov tseem ceeb nrog lub zog hluav taws xob.Tab sis kom siv hluav taws xob, peb pom tias peb tau siv ntau lub ntiaj teb cov peev txheej uas nws yog lub sijhawm los nrhiav lwm qhov chaw siv hluav taws xob.

Peb tau siv dej thiab cua los tsim hluav taws xob, tab sis nrog kev tshawb pom ntawm cov thee, kev siv cov khoom siv txuas ntxiv tau poob qis.Tom qab ntawd, xyoo 1878, William Armstrong tau tsim thawj lub tshuab hluav taws xob siv dej, uas tsim hluav taws xob los ntawm cov dej ntws.Qhov teeb meem loj txog cov khoom siv hluav taws xob tauj dua tshiab yog tias nws yuav siv sij hawm ntau heev los teeb tsa thiab tseem muab lub zog tsawg heev.

Ntawm no nyob rau hauv lub ntiaj teb niaj hnub no, cov ntsiab lus "Occupancy Savings" thiab "Daylight Savings" muaj nyob.Nyeem ntxiv hauv tsab xov xwm kom paub cov tswv yim tshiab los txuag thiab txo kev siv hluav taws xob.

Kev txuag hluav taws xob: -

Yog tias koj nug ib tus txiv neej zoo txog lub tsev twg nws xav tau ntawm ib qho uas tau da dej hauv lub hnub ci thiab lwm qhov uas yog shadowed los ntawm cov tsev siab, koj yuav tau txais cov lus teb tias ib tug da dej nyob rau hauv tshav ntuj yuav ua tau zoo dua.Yog vim li cas tom qab tib yam yog tias koj tsis tas yuav txhawj txog qhov muag hluav taws xob thaum koj muaj lub hnub saum koj los muab lub teeb.

Kev txuag hluav taws xob nruab hnub, hauv cov ntsiab lus yooj yim, suav tias yog kev txuag hluav taws xob los ntawm kev siv lub hnub ci ntuj los muab lub teeb ci rau lub tsev.Cia peb nkag siab lub ntsiab lus hauv kev nthuav dav txog kev tsim kho thiab sensors.

Hloov hauv Architecture: -

Peb nyuam qhuav kawm tias peb tuaj yeem txuag hluav taws xob raws li kev siv lub hnub ci ntuj es tsis yog qhov muag teeb.Yog li nws tsuas yog ib qho teeb meem ntawm kev xaiv lub hnub ci tshaj lub teeb ci.Tab sis nyob rau hauv lub hav zoov pob zeb, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam qis, tej zaum koj yuav pom tias tshav ntuj yog tsawg heev.

Txawm nyob rau hauv pem teb saum toj kawg nkaus, qee zaum nws nyuaj rau ntes lub hnub ci li skyscrapers nyob ib puag ncig, thaiv lub hnub.Tab sis tam sim no, muaj qhov rais, vaj huam sib luag, thiab cov iav tsom iav txuas rau ntawm phab ntsa thiab qab nthab thaum tsim tsev.Ua li no, nws yuav coj lub teeb siab tshaj plaws hauv tsev kom txuag hluav taws xob zoo.

Photocell:-

Lub photocell lossis photosensor yog ib hom khoom siv uas tuaj yeem paub qhov teeb pom kev zoo ntawm chav tsev.Muaj ambient light sensors uas txuas nrog lub teeb.Cia peb ua piv txwv yooj yim kom nkag siab tias photocell yog dab tsi.Thaum koj hloov koj lub xov tooj ntawm phau ntawv ci ci mus rau nws pib-brightness, koj pom tias lub xov tooj kho qhov ci raws li lub teeb nyob ib puag ncig.

Cov yam ntxwv no txuag koj los ntawm kev txo qis lub xov tooj lub teeb ci txhua zaus koj nyob hauv ib puag ncig uas muaj teeb pom kev zoo.Yog vim li cas tom qab qhov khawv koob no yog tias qee qhov photodiodes txuas nrog rau cov zaub ntawm koj lub xov tooj, uas khaws cov nqi ntawm lub teeb thiab xa hluav taws xob raws li qhov qub.

Ib yam li ntawd, thaum siv rau qhov muag teev, yuav yog ib txoj hauv kev zoo rau kev txuag lub zog.Lub teeb pom kev zoo yuav ntes thaum nws xav tau qhib, thiab yog li nws tuaj yeem txuag nyiaj suav tsis txheeb yog tias siv thoob ntiaj teb.Lwm qhov tseem ceeb ntawm cov cuab yeej no yog tias nws tuaj yeem ua raws li lub teeb thiab ci ntsa iab uas xav tau rau tib neeg lub qhov muag, yog li nws ua haujlwm raws li.Ib qho khoom siv ntxiv uas tau ntxiv rau lub photocell yog qhov chaw nyob sensor.Cia peb dhia mus ntxiv seb qhov ntawd yog dab tsi.

Cov neeg nyob sensors: -

Koj yuav tsum tau pom lub teeb liab uas yuav ntsais rau hauv chav dej, hauv tsev thiab chav sib tham.Tej zaum yuav muaj ib lub sij hawm uas tej zaum koj yuav tau xav tias yuav tsum muaj lub koob yees duab neeg soj xyuas qhov twg tsoom fwv neeg soj xyuas cov neeg.Nws tau txawm ncaws ntau qhov kev koom tes txog cov koob yees duab neeg soj xyuas no.

Zoo, rau koj poob siab, cov no yog cov neeg nyob sensors.Ua kom yooj yim, lawv tau tsim los xyuas cov neeg taug kev dhau los lossis nyob hauv ib chav.

Cov neeg nyob sensors muaj ob hom: -

1. Infrared sensors

2. Ultrasonic sensors.

3. Microwave sensors

Lawv ua haujlwm raws li hauv qab no: -

1. Infrared sensors: -

Cov no yog cov cua kub sensors, thiab lawv tau tsim los qhib hluav taws xob los hloov lub teeb lub teeb thaum tus neeg hla dhau.Nws pom cov kev hloov pauv hauv feeb hauv cua sov thiab yog li teeb pom kev hauv chav.Qhov teeb meem loj rau lub sensor no yog tias nws tsis tuaj yeem ntes yav dhau los ib yam khoom opaque.

2. Ultrasonic sensors: -

Txhawm rau kov yeej cov teeb meem ntawm infrared sensors, ultrasonic sensors txuas rau lub ntsiab hloov.Lawv ntes cov lus tsa suab thiab xa hluav taws xob uas tig rau ntawm lub teeb.Qhov no yog qhov hnyav heev thiab nruj, thiab txawm tias me ntsis txav tuaj yeem tig lub teeb.Ultrasonic sensors kuj siv rau hauv kev ruaj ntseg tswb.

Thaum nws los txog rau kev siv cov sensors, feem ntau yog ob qho tib si siv ib txhij thiab txuas ua ke kom lub teeb pom kev zoo tuaj yeem txo qis thiab lub zog tuaj yeem txuag tau thiab kuj tsis muaj qhov tsis xis nyob thaum koj xav tau lub teeb.

Cov lus xaus:-

Thaum nws los txog kev txuag hluav taws xob, txawm tias cov kauj ruam me me xws li taug kev luv luv es tsis siv lub tsheb, hloov cov cua txias thaum tsis xav tau yog qhov tseem ceeb heev thiab pab tau ntau heev.

Vim yog tib neeg yuam kev thiab tsis tuaj yeem tua lub teeb thaum tsis xav tau, nws kwv yees tias yuav luag 60% ntawm cov nqi hluav taws xob tuaj yeem txuag tau rau cov chaw uas xav tau rau lub sijhawm tshwj xeeb, xws li ib feem ntawm txoj hauv kev lossis chav dej.

Txhua tus neeg yuav tsum tau cog lus rau nruab teeb pom kev zoo nrog cov sensors xws li nyob thiab photocells vim tias lawv yuav tsis tsuas txuag nyiaj tab sis kuj pab peb rau lub neej yav tom ntej zoo dua nrog kev siv hluav taws xob tsawg thiab siv tau zoo.
