Nakong ea kamora lefu la seoa, re lumela hore li-sensor tsa infrared li bohlokoa letsatsi le letsatsi. Ha re le leetong, re hloka ho lekanya mocheso khafetsa pele re ka fihla moo re eang. E le tekanyo ea mocheso e nang le li-sensor tse ngata tsa infrared, ha e le hantle, ho na le mesebetsi e mengata ea bohlokoa. Ka mor'a moo, a re shebeng hantle sensor ea infrared.
Kenyelletso ea li-sensor tsa infrared
Ntho leha e le efe e ka holimo ho zero e feletseng (-273 ° C) e lula e ntša matla a infrared sebakeng se potolohileng, ka tsela ea tšoantšetso. 'Me kutlo ea infrared, e khona ho utloa matla a infrared a ntho ebe e e fetola likarolo tsa motlakase. Sensor ea infrared e na le sistimi ea optical, ntho ea ho bona le potoloho ea phetoho.
Sistimi ea Optical e ka aroloa ka mofuta oa phetisetso le mofuta oa ponts'o ho latela sebopeho se fapaneng. Phetiso e hloka likarolo tse peli, e 'ngoe e fetisang infrared le e' ngoe e amohela infrared. Ka lehlakoreng le leng, reflector e hloka sensor e le 'ngoe feela ho bokella tlhahisoleseding e lakatsehang.
Ntho ea ho lemoha e ka aroloa ka karolo ea ho lemoha mocheso le photoelectric detecting element ho ea ka molao-motheo oa ho sebetsa. Thermitor ke tsona tse sebelisoang haholo ka ho fetisisa. Ha thermistor e le tlas'a mahlaseli a mahlaseli a kotsi, mocheso oa eketseha, 'me ho hanyetsa ho fetoha (phetoho ena e ka ba kholoanyane kapa e nyenyane, hobane thermistor e ka aroloa ka mocheso o motle oa mocheso oa mocheso oa mocheso le mocheso o fosahetseng oa mocheso oa mocheso), o ka fetoloang hore e be pontšo ea motlakase. ka potoloho ea ho sokoloha. Lintho tsa ho lemoha ha photoelectric hangata li sebelisoa e le li-photosensitive elements, tseo hangata li entsoeng ka lead sulfide, lead selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy, germanium le silicon doped materials.
Ho ea ka li-circuits tse fapaneng tsa ts'ebetso le li-conversion, li-sensor tsa infrared li ka aroloa ka mofuta oa analog le oa dijithale. Potoloho ea ts'ebetso ea mats'oao ea sensor ea analog pyroelectric infrared ke tube e sebetsang tšimong, athe potoloho ea ts'ebetso ea mats'oao ea sensor ea infrared ea dijithale ke chip ea dijithale.
Mesebetsi e mengata ea sensor ea infrared e bonoa ka litumello tse fapaneng le motsoako oa likarolo tse tharo tse hlokolosi: sistimi ea optical, element ea ho lemoha le potoloho ea phetoho. Ha re shebeng libaka tse ling moo li-sensor tsa infrared li entseng phapang.
Tšebeliso ea Sensor ea Infrared
1. Ho fumanoa ha Khase
Molao-motheo oa infrared optical sensor ea khase ke mofuta o ipapisitseng le litšobotsi tse haufi tsa infrared spectral selective absorption ea limolek'hule tse fapaneng tsa khase, ts'ebeliso ea khatello ea khase le kamano ea matla a ho monya (molao oa Lambert - Bill Lambert Beer) ho tseba le ho tseba hore na karolo ea khase e kae. sesebelisoa sa ho utloa.
Li-sensor tsa infrared li ka sebelisoa ho fumana 'mapa oa tlhahlobo ea infrared joalo ka ha ho bonts'itsoe setšoantšong se kaholimo. Limolek'hule tse entsoeng ka liathomo tse fapaneng li tla kenella ka tlas'a mahlaseli a lebone la infrared ka maqhubu a tšoanang, e leng se etsang hore ho be le liphetoho ho matla a leseli la infrared. Ho ea ka litlhōrō tse fapaneng tsa maqhubu, mefuta ea khase e ka har'a motsoako e ka khethoa.
Ho ea ka boemo ba tlhōrō e le 'ngoe ea infrared absorption, ke lihlopha life tse teng ka molek'hule oa khase feela tse ka tsejoang. Ho tseba ka nepo mofuta oa khase, re hloka ho sheba maemo a litlhoro tsohle tsa ho monya sebakeng sa infrared sa khase, e leng, monoana oa infrared oa khase. Ka spectrum ea infrared, litaba tsa khase e 'ngoe le e' ngoe e motsoako li ka hlahlojoa kapele.
Li-sensor tsa khase ea infrared li sebelisoa haholo indastering ea petrochemical, metallurgical, merafong ea boemo ba ts'ebetso, tlhahlobo ea tšilafalo ea moea le ho lemoha ho amanang le carbon neutralization, temo le liindasteri tse ling. Hajoale, li-laser tsa bohareng ba infrared li theko e boima. Ke lumela hore nakong e tlang, ka palo e kholo ea liindasteri tse sebelisang li-sensor tsa infrared ho lemoha khase, li-sensor tsa khase ea infrared li tla ba tse ntle haholo le tse theko e tlaase.
2. Infrared Distance Measure
Sensor sa infrared range ke mofuta oa sesebelisoa sa ho lemoha, ke ho sebelisa infrared joalo ka mokhoa oa ho metha, mefuta e mengata ea litekanyo, nako e khuts'oane ea karabelo, e sebelisoang haholo mahlaleng a sejoale-joale le theknoloji, ts'ireletso ea naha le masimo a indasteri le a temo.
Sensor e fapaneng ea infrared e na le li-diode tse fetisang le ho amohela li-diode, tse sebelisang kutlo ea infrared ho hlahisa lebone la khanya ea infrared, ho etsa mokhoa oa ho bonahatsa ka mor'a ho khantša ntho, ho bonahatsa ho sensor ka mor'a ho amohela letšoao, ebe o sebelisa CCD. ts'ebetso ea litšoantšo e amohelang ho fetisoa le ho amohela data ea phapang ea nako. Sebaka sa ntho e baloa ka mor'a ho sebetsa ka mochine oa matšoao. Sena se ka sebelisoa eseng feela holim'a libaka tsa tlhaho, empa hape le liphanele tse bonahatsang. Ho lekanya sebaka, karabelo ea maqhubu a phahameng, e loketseng maemo a thata a indasteri.
3. Phetiso ea Infrared
Phetiso ea data e sebelisang li-sensor tsa infrared le eona e sebelisoa haholo. Taolo e hole ea TV e sebelisa mats'oao a phetiso ea infrared ho laola TV u le hole; Lithelefono tsa cellular li khona ho fetisa data ka infrared transmission. Tsena ke lits'ebetso tse bileng teng ho tloha ha theknoloji ea infrared e qala ho ntlafatsoa.
4. Setšoantšo sa Thermal sa Infrared
Thermal imager ke kuns e sa sebetseng e ka nkang mahlaseli a infrared a hlahisoang ke lintho tsohle tseo mocheso oa tsona o leng holimo ho feta zero. Sets'oants'o se futhumatsang qalong se ile sa ntlafatsoa e le sesebelisoa sa ho lebela sesole le pono ea bosiu, empa ha se ntse se sebelisoa haholo, theko e ile ea theoha, kahoo ea atolosa haholo tšimo ea kopo. Lisebelisoa tsa litšoantšo tse futhumatsang li kenyelletsa liphoofolo, temo, meaho, ho lemoha khase, lisebelisoa tsa indasteri le tsa sesole, hammoho le ho lemoha ha batho, ho sala morao le ho tsebahatsa. Lilemong tsa morao tjena, setšoantšo sa mocheso oa infrared se 'nile sa sebelisoa libakeng tse ngata tsa sechaba ho lekanya ka potlako mocheso oa lihlahisoa.
5. Infrared Induction
Infrared induction switch ke sesebelisoa sa taolo ea othomathike se ipapisitseng le theknoloji ea infrared induction. E hlokomela mosebetsi oa eona oa ho laola ka boiketsetso ka ho utloa mocheso oa infrared o tsoang lefatšeng le kantle. E khona ho bula mabone ka potlako, mamati a ikemetseng, lialamo tse thibelang bosholu le lisebelisoa tse ling tsa motlakase.
Ka lense ea Fresnel ea sensor ea infrared, leseli le hasaneng la infrared le hlahisoang ke 'mele oa motho le ka utluoa ke switch, e le ho hlokomela mesebetsi e fapaneng ea taolo ea othomathike joalo ka ho bonesa lebone. Lilemong tsa morao tjena, ka botumo ba lehae le bohlale, ho sebelisoa ha infrared ho sebelisoa ka har'a makotikoti a lithōle a bohlale, matloana a bohlale, li-switches tse bohlale, mamati a induction le lihlahisoa tse ling tse bohlale. Infrared sensing ha se feela mabapi le ho lemoha batho, empa e lula e ntlafatsoa ho fihlela mesebetsi e mengata.
Qetello
Lilemong tsa morao tjena, indasteri ea Inthanete ea Lintho e tsoetse pele ka potlako 'me e na le tebello e pharaletseng ea' maraka. Boemong bona, 'maraka oa sensor ea infrared le ona e bile kholo e eketsehileng. Ka hona, sekhahla sa mmaraka sa China sa infrared detector se ntse se hola. Ho latela lintlha, ka 2019, boholo ba mmaraka oa China oa infrared detector o ka bang li-yuan tse limilione tse 400, ka 2020 kapa li-yuan tse ka bang limilione tse 500. Ha e kopantsoe le tlhoko ea tekanyo ea mocheso oa infrared ea seoa le ho se nke lehlakore ha khase bakeng sa ho sibolloa ha khase ea infrared, boholo ba mmaraka ba li-sensor tsa infrared bo tla ba boholo nakong e tlang.
