Nyob rau hauv lub sijhawm tom qab kis mob, peb ntseeg tias infrared sensors yog qhov tseem ceeb txhua hnub.Nyob rau hauv tus txheej txheem ntawm commuting, peb yuav tsum tau mus los ntawm kev ntsuas kub dua thiab dua ua ntej peb mus txog peb lub hom phiaj.Raws li kev ntsuas kub nrog ntau tus infrared sensors, qhov tseeb, muaj ntau lub luag haujlwm tseem ceeb.Tom ntej no, cia peb saib zoo ntawm lub infrared sensor.
Taw qhia rau Infrared Sensors
Txhua yam saum toj kawg nkaus xoom (-273 ° C) yog tas li emitting infrared zog mus rau qhov chaw nyob ib puag ncig, yog li hais.Thiab infrared sensor, muaj peev xwm hnov lub zog infrared ntawm cov khoom thiab hloov mus rau hauv cov khoom hluav taws xob.Infrared sensor muaj cov kab ke kho qhov muag, kuaj pom cov khoom thiab kev hloov pauv hauv Circuit Court.
Optical system tuaj yeem muab faib ua hom kis tau tus mob thiab hom kev xav raws li cov qauv sib txawv.Kev sib kis yuav tsum muaj ob yam, ib qho kis tau tus mob infrared thiab ib qho tau txais infrared.Lub reflector, ntawm qhov tod tes, xav tau tsuas yog ib lub sensor los sau cov ntaub ntawv xav tau.
Cov khoom kuaj pom tuaj yeem muab faib ua thermal detecting element thiab photoelectric detecting element raws li kev ua haujlwm.Thermistor yog cov thermistor siv dav tshaj plaws.Thaum lub thermistor raug rau hluav taws xob infrared, qhov kub thiab txias nce, thiab kev hloov pauv hloov (qhov kev hloov no yuav loj dua lossis me dua, vim tias cov thermistor tuaj yeem muab faib ua qhov zoo kub coefficient thermistor thiab qhov kub tsis zoo coefficient thermistor), uas tuaj yeem hloov mus rau hauv cov teeb liab hluav taws xob. los ntawm lub converter Circuit Court.Photoelectric nrhiav pom cov ntsiab lus feem ntau yog siv los ua cov ntsiab lus photosensitive, feem ntau yog ua los ntawm txhuas sulfide, lead selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy, germanium thiab silicon doped cov ntaub ntawv.
Raws li qhov sib txawv ntawm cov teeb liab ua thiab hloov hluav taws xob, infrared sensors tuaj yeem muab faib ua hom analog thiab digital.Lub teeb liab ua Circuit Court ntawm analog pyroelectric infrared sensor yog teb-zoo raj, thaum lub teeb liab ua Circuit Court ntawm cov pyroelectric infrared sensor yog digital nti.
Ntau lub zog ntawm infrared sensor tau pom los ntawm kev sib txawv ntawm qhov sib txawv thiab kev sib xyaw ua ke ntawm peb yam rhiab heev: qhov system kho qhov muag, nrhiav pom thiab hloov pauv hloov hluav taws xob.Cia peb saib qee qhov chaw uas infrared sensors tau ua qhov txawv.
Kev siv ntawm Infrared Sensor
1. Kev Ntsuas Roj
Infrared optical txoj cai ntawm roj sensor yog ib hom raws li nyob ze infrared spectral xaiv absorption yam ntxwv ntawm txawv roj molecules, kev siv cov roj concentration thiab nqus zog kev sib raug zoo (Lambert - Bill Lambert Beer txoj cai) los txheeb xyuas thiab txiav txim siab concentration ntawm roj Cheebtsam roj. ntaus ntawv.
Infrared sensors tuaj yeem siv tau kom tau txais daim ntawv qhia infrared tsom xam raws li qhia hauv daim duab saum toj no.Cov molecules tsim los ntawm txawv atoms yuav raug infrared nqus nyob rau hauv lub irradiation ntawm infrared lub teeb ntawm tib zaus, uas ua rau muaj kev hloov nyob rau hauv qhov siv ntawm lub teeb infrared.Raws li qhov sib txawv nthwv dej peaks, hom roj muaj nyob hauv qhov sib tov tuaj yeem txiav txim siab.
Raws li txoj hauj lwm ntawm ib qho infrared absorption ncov, tsuas yog cov pab pawg twg muaj nyob hauv cov roj molecule tuaj yeem txiav txim siab.Txhawm rau txiav txim siab txog hom roj, peb yuav tsum tau saib cov haujlwm ntawm txhua qhov nqus siab tshaj plaws nyob rau hauv nruab nrab-infrared cheeb tsam ntawm cov roj, uas yog, infrared nqus ntiv tes ntawm cov roj.Nrog infrared spectrum, cov ntsiab lus ntawm txhua cov pa hauv qhov sib tov tuaj yeem txheeb xyuas sai.
Infrared gas sensors yog dav siv nyob rau hauv petrochemical, metallurgical kev lag luam, kev ua hauj lwm mob mining, huab cua paug xyuas thiab carbon neutralization ntsig txog kev tshawb nrhiav, kev ua liaj ua teb thiab lwm yam lag luam.Tam sim no, mid-infrared lasers yog kim.Kuv ntseeg tias yav tom ntej, nrog rau ntau cov kev lag luam uas siv infrared sensors los ntes roj, infrared gas sensors yuav ua tau zoo dua thiab pheej yig dua.
2. Infrared Distance Ntsuas
Infrared ranging sensor yog ib hom kev ntsuas ntsuas, yog siv infrared raws li qhov nruab nrab ntawm kev ntsuas qhov system, kev ntsuas dav dav, lub sijhawm teb luv luv, feem ntau yog siv hauv kev tshawb fawb niaj hnub thiab thev naus laus zis, kev tiv thaiv hauv tebchaws thiab kev lag luam thiab kev ua liaj ua teb.
Infrared ranging sensor muaj ib khub ntawm infrared teeb liab xa thiab txais diodes, siv lub infrared range sensor kom emit ib beam ntawm infrared teeb, tsim ib tug xav txog cov txheej txheem tom qab irradiating rau cov khoom, reflecting mus rau lub sensor tom qab tau txais lub teeb liab, thiab ces siv CCD. cov duab ua tau txais kev xa tawm thiab tau txais cov ntaub ntawv sib txawv ntawm lub sijhawm.Qhov kev ncua deb ntawm cov khoom yog xam tom qab ua tiav los ntawm lub teeb liab processor.Qhov no tuaj yeem siv tsis tau tsuas yog rau ntawm qhov chaw ntuj, tab sis kuj nyob rau ntawm cov khoom siv hluav taws xob.Ntsuas qhov deb, siab zaus teb, haum rau hnyav kev lag luam ib puag ncig.
3. Kev xa tawm Infrared
Kev xa cov ntaub ntawv siv infrared sensors kuj tau siv dav.TV chaw taws teeb tswj siv infrared kis tau tus mob signals rau remotely tswj lub TV;Cov xov tooj ntawm tes tuaj yeem xa cov ntaub ntawv los ntawm kev sib kis infrared.Cov no yog cov ntawv thov uas tau nyob ib puag ncig txij li infrared thev naus laus zis tau tsim thawj zaug.
4. Infrared Thermal Image
Thermal imager yog ib qho passive sensor uas tuaj yeem ntes cov hluav taws xob infrared tawm los ntawm txhua yam khoom uas nws qhov kub thiab txias siab tshaj li xoom.Lub thermal imager yog Ameslikas tsim los ua tub rog soj ntsuam thiab kev pom kev hmo ntuj, tab sis raws li nws tau siv ntau dua, tus nqi poob, yog li nthuav dav hauv daim ntawv thov.Daim ntawv thov thermal imager muaj xws li tsiaj txhu, kev ua liaj ua teb, tsev, kev tshawb nrhiav roj, kev lag luam thiab kev siv tub rog, nrog rau kev tshawb nrhiav tib neeg, taug qab thiab txheeb xyuas.Nyob rau hauv xyoo tas los no, cov duab thermal infrared tau siv nyob rau hauv ntau qhov chaw pej xeem los ntsuas qhov kub ntawm cov khoom.
5. Infrared Induction
Infrared induction hloov yog ib qho kev tswj tsis siv neeg hloov raws li infrared induction technology.Nws paub txog nws txoj kev tswj tsis siv neeg los ntawm kev hnov cov cua sov infrared tawm ntawm lub ntiaj teb sab nraud.Nws tuaj yeem qhib tau sai sai, lub qhov rooj tsis siv neeg, lub tswb tiv thaiv tub sab thiab lwm yam khoom siv hluav taws xob.
Los ntawm Fresnel lens ntawm lub infrared sensor, lub teeb tawg infrared tawm los ntawm tib neeg lub cev tuaj yeem hnov los ntawm kev hloov, kom paub txog ntau yam kev tswj tsis siv neeg xws li tig lub teeb.Nyob rau hauv xyoo tas los no, nrog lub koob npe nrov ntawm lub tsev ntse, infrared sensing kuj tau siv nyob rau hauv cov thoob khib nyiab ntse, chav dej ntse, ntse tes taw keyboards, induction qhov rooj thiab lwm yam khoom ntse.Infrared sensing tsis yog tsuas yog hais txog kev hnov neeg, tab sis yog hloov kho tas li kom ua tiav ntau lub zog.
Xaus
Nyob rau hauv xyoo tas los no, Internet of Things kev lag luam tau tsim kho sai thiab muaj kev lag luam dav dav.Nyob rau hauv cov ntsiab lus no, lub lag luam infrared sensor kuj tau loj hlob ntxiv.Yog li ntawd, Tuam Tshoj tus infrared ntes kev lag luam nplai txuas ntxiv mus.Raws li cov ntaub ntawv, nyob rau hauv 2019, Tuam Tshoj tus infrared detector lag luam loj ntawm ze li ntawm 400 lab yuan, los ntawm 2020 los yog ze li ntawm 500 lab yuan.Ua ke nrog kev thov rau infrared ntsuas kub ntawm kev sib kis thiab carbon neutralization rau infrared gas detection, kev lag luam loj ntawm infrared sensors yuav loj heev yav tom ntej.
