Xilligii faafitaanka ka dib, waxaan aaminsanahay in dareemayaasha infrared-ka aan laga maarmin maalin kasta. Geedi socodka safarka, waxaan u baahanahay inaan mar kale marno cabirka heerkulka ka hor inta aanan gaarin meesha aan u socono. Sida cabbirka heerkulka oo leh tiro badan oo dareemayaasha infrared, dhab ahaantii, waxaa jira doorar badan oo muhiim ah. Marka xigta, aan si fiican u eegno dareenka infrared.
Hordhac Sensors Infrared
Wax kasta oo ka sarreeya eber dhammaystiran (-273 ° C) ayaa si joogto ah tamarta infrared u sii daaya meel bannaan oo ku wareegsan, si loo hadlo. Dareemaha infrared-ka, ayaa awood u leh inuu dareemo tamarta infrared ee shayga oo u beddelo qaybaha korantada. Dareemaha infrared wuxuu ka kooban yahay nidaamka indhaha, ogaanshaha curiyaha iyo wareegga beddelka.
Nidaamka indhaha waxaa loo qaybin karaa nooca gudbinta iyo nooca milicsiga iyadoo loo eegayo qaab dhismeed kala duwan. Gudbintu waxay u baahan tahay laba qaybood, mid gudbiya infrared iyo mid helaya infrared. Milicsigu, dhinaca kale, wuxuu u baahan yahay hal dareeme si uu u ururiyo macluumaadka la rabo.
Cutubka ogaanshaha waxa loo qaybin karaa walxo ogaanshaha kulaylka iyo walxaha wax ogaanaya ee korantada sida waafaqsan mabda'a shaqada. Thermistors waa kuleyliyeyaasha ugu badan ee la isticmaalo. Marka thermistor uu ku dhaco shucaaca infrared, heerkulku wuu kordhaa, iska caabintuna way is beddeshaa (isbeddelkani wuu weynaan karaa ama wuu ka yarayn karaa, sababtoo ah thermistor waxa loo qaybin karaa heer-kulka saxda ah ee heerkulbeegga iyo thermistor-ka heerkulka taban), kaas oo loo rogi karo soosaarka signalka korantada. iyada oo loo marayo wareegga beddelka. Walxaha ogaanshaha sawir-qaadista ayaa caadi ahaan loo isticmaalaa sidii walxo sawir-qaadis ah, oo inta badan laga sameeyo sunta rasaasta, ledhka selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy, germanium iyo walxo silikoon ah.
Marka loo eego hababka is-beddelka calaamadaha kala duwan, dareemayaasha infrared waxaa loo qaybin karaa analog iyo nooca dhijitaalka ah. Wareegga habaynta signalada ee analoog pyroelectric infrared sensor waa tuubo saamayn ku leh goobta, halka wareegga habaynta signalada ee dareemaha infrared pyroelectric dhijitaalka ah uu yahay chip dhijitaal ah.
Shaqooyin badan oo ah dareemaha infrared ayaa lagu gartaa iyada oo loo marayo isbeddello kala duwan iyo isku-dar ah saddex qaybood oo xasaasi ah: nidaamka indhaha, walxaha ogaanshaha iyo wareegga beddelka. Aynu eegno meelo kale oo dareemayaasha infrared-ka ay isbeddel ku sameeyeen.
Codsiga Dareemka Infrared
1. Ogaanshaha Gaaska
Mabda 'infrared optical mabda'a gaaska shidma waa nooc ku salaysan infrared u dhow sifooyinka nuugista spectral spectral ee unugyada gaaska kala duwan, isticmaalka xoojinta gaaska iyo xidhiidhka xoogga nuugista (Lambert - sharciga Lambert Beer) si loo aqoonsado loona go'aamiyo fiirsashada gaaska qaybta gaaska qalabka dareenka.
Dareemayaasha infrared ayaa loo isticmaali karaa si loo helo khariidadda falanqaynta infrared sida ku cad shaxanka sare. Molecules ka kooban atamka kala duwan ayaa mari doona nuugista infrared hoosteeda shucaaca iftiinka infrared isla inta jeer ee isku midka ah, taas oo keenta isbeddel ku yimaada xoojinta iftiinka infrared. Marka loo eego mawjadaha ugu sarreeya ee kala duwan, noocyada gaaska ku jira isku dhafka ayaa la go'aamin karaa.
Marka loo eego booska ugu sarreeya nuugista infrared-ka, kaliya waxa kooxaha ka jira molecule gaaska ayaa la go'aamin karaa. Si aad si sax ah u go'aamiso nooca gaaska, waxaan u baahanahay inaan eegno jagooyinka dhammaan meelaha ugu sarreeya ee nuugista ee gobolka dhexe ee gaaska, kuwaas oo ah faraha nuugista infrared ee gaaska. Iyada oo leh spectrum infrared, waxa ku jira gaas kasta oo isku dhafan ayaa si dhakhso ah loo falanqeyn karaa.
Dareemayaasha gaaska infrared ayaa si weyn loogu isticmaalaa petrochemical, warshadaha birta, macdanta xaaladda shaqada, la socodka wasakhowga hawada iyo ogaanshaha ka saarista kaarboonka, beeraha iyo warshadaha kale. Waqtigan xaadirka ah, laydhka dhexe ee infrared waa qaali. Waxaan aaminsanahay in mustaqbalka, oo leh tiro badan oo warshado ah oo isticmaalaya dareemayaasha infrared si loo ogaado gaaska, dareemayaasha gaaska infrared waxay noqon doonaan kuwo aad u fiican oo ka jaban.
2. Cabbirka Fogaanta Infrared
Dareemayaasha kala duwan ee infrared waa nooc ka mid ah aaladaha dareenka, waa in loo isticmaalo infrared sida dhexdhexaadinta nidaamka cabbirka, cabbirka cabbirka ballaaran, waqtiga jawaabta gaaban, oo inta badan loo isticmaalo sayniska iyo tignoolajiyada casriga ah, difaaca qaranka iyo beeraha warshadaha iyo beeraha.
Dareemayaasha kala duwan ee infrared-ku waxa ay leeyihiin lammaane ka mid ah calaamadaha gudbinta iyo helitaanka diodes, iyada oo la adeegsanayo dareeraha kala duwan ee infrared si uu u soo saaro iftiinka iftiinka infrared, samaynta habka milicsiga ka dib marka uu iftiimiyo shayga, ka tarjumaya dareenka ka dib marka uu helo signalka, ka dibna isticmaalaya CCD habaynta sawir qaadashada gudbinta iyo helitaanka xogta kala duwanaanshaha wakhtiga. Masaafada shayga waxaa la xisaabiyaa ka dib markii la farsameeyo processor-ka signalka. Tan waxaa loo isticmaali karaa ma aha oo kaliya dusha dabiiciga ah, laakiin sidoo kale muraayadaha milicsiga. Cabbiraadda fogaanta, jawaab celinta soo noqnoqda sare, oo ku habboon jawiga warshadaha adag.
3. Gudbinta Infrared
Gudbinta xogta iyadoo la adeegsanayo dareemayaasha infrared ayaa sidoo kale si ballaaran loo isticmaalaa. Kontroolka fog ee TV-ga wuxuu isticmaalaa calaamadaha gudbinta infrared si uu meel fog uga xakameeyo TV-ga; Taleefannada gacanta ayaa xogta ku gudbin kara gudbinta infrared. Kuwani waa codsiyo jiray tan iyo markii ugu horreysay ee tignoolajiyada infrared la sameeyay.
4. Sawirka Kulaylka Infrared
Sawir-qaadaha kulaylka waa dareeme dadban oo qaban kara shucaaca infrared-ka ee ay sii daayaan dhammaan walxaha heerkulkoodu ka sarreeyo eber dhammaystiran. Sawir-qaadaha kulaylka ayaa markii hore loo sameeyay sida ilaalinta millatariga iyo aaladda aragga habeenkii, laakiin markii ay noqotay mid si ballaaran loo isticmaalo, qiimihiisu hoos u dhacay, sidaas darteed si weyn u ballaariyay goobta codsiga. Codsiyada sawirada kulaylka waxaa ka mid ah xayawaan, beero, dhismo, ogaanshaha gaaska, codsiyada warshadaha iyo militariga, iyo sidoo kale ogaanshaha aadanaha, dabagalka iyo aqoonsiga. Sanadihii la soo dhaafay, sawirka kulaylka infrared ayaa loo isticmaalay meelo badan oo dadweyne si ay si dhakhso ah u cabbiraan heerkulka alaabta.
5. Induction Infrared
Dareemaha soo-saarka infrared-ka waa beddelka kontoroolka otomaatiga ah ee ku saleysan tignoolajiyada soo-saarka infrared. Waxay garwaaqsataa shaqadeeda xakamaynta tooska ah iyadoo dareemaysa kulaylka infrared ee ka soo baxaya adduunka dibadda. Waxay si dhakhso ah u furi kartaa nalalka, albaabbada otomaatiga ah, alaarmiga ka hortagga tuugada iyo qalabka kale ee korontada.
Iyada oo loo marayo muraayada Fresnel ee dareemayaasha infrared, iftiinka infrared ee kala firdhiyey ee ka soo baxa jidhka bini'aadamka waxaa lagu dareemi karaa beddelka, si loo ogaado hawlaha kala duwan ee xakamaynta tooska ah sida shid iftiinka. Sanadihii la soo dhaafay, oo caan ku ah guriga smart, dareenka infrared ayaa sidoo kale loo isticmaalay gasacadaha qashinka ee smart, musqulaha xariifka ah, furayaasha dhaq-dhaqaaqa smart, albaabada induction iyo alaabo kale oo caqli badan. Dareenka infrared ma aha oo kaliya dareenka dadka, laakiin si joogto ah ayaa loo cusbooneysiiyaa si loo gaaro hawlo badan.
Gabagabo
Sannadihii ugu dambeeyay, Internet-ka warshadaha Waxyaabaha ayaa si degdeg ah u horumaray waxayna leedahay rajo suuqeed ballaaran. Xaaladdan oo kale, suuqa dareemayaasha infrared ayaa sidoo kale ahaa koritaan dheeraad ah. Sidaa darteed, miisaanka suuqa ee infrared ee Shiinaha ayaa sii waday inuu koro. Marka loo eego xogta, sanadka 2019, cabbirka suuqa wax baaraha infrared ee Shiinaha oo ku dhow 400 milyan yuan, marka la gaaro 2020 ama ku dhawaad 500 milyan yuan. Marka lagu daro baahida loo qabo cabbirka heerkulka infrared ee faafitaanka iyo ka hortagga kaarboonka ee ogaanshaha gaaska infrared, cabbirka suuqa ee dareemayaasha infrared-ka ayaa noqon doona mid weyn mustaqbalka.
