Ngexesha le-post-bhubhane, sikholelwa ukuba izinzwa ze-infrared ziyimfuneko yonke imihla. Kwinkqubo yokuhamba, kufuneka siphinde senze umlinganiselo wobushushu ngaphambi kokuba sifike kwindawo esiya kuyo. Njengomlinganiselo weqondo lokushisa kunye nenani elikhulu le-infrared sensors, enyanisweni, kukho iindima ezininzi ezibalulekileyo. Okulandelayo, makhe sijonge kakuhle kwi-infrared sensor.
Intshayelelo kwiiSensori ze-Infrared
Nantoni na engaphezulu kwe-zero epheleleyo (-273 ° C) ihlala ikhupha amandla e-infrared kwindawo ejikelezileyo, ngoko kuthetha. Kwaye inzwa ye-infrared, iyakwazi ukuva amandla e-infrared ento kwaye iguqule ibe ngamacandelo ombane. I-sensor ye-infrared iqulethe inkqubo ye-optical, i-elementi yokufumanisa kunye nesekethe yokuguqula.
Inkqubo ye-Optical inokwahlulwa ibe luhlobo lothumelo kunye nohlobo lokubonisa ngokwesakhiwo esahlukileyo. Ugqithiso lufuna amacandelo amabini, enye i-infrared yokudlulisela kwaye enye ifumana i-infrared. Umboniso, kwelinye icala, udinga inzwa enye kuphela ukuqokelela ulwazi olufunekayo.
Into yokufumanisa inokwahlulwa ibe yinto yokufumanisa i-thermal kunye ne-photoelectric detecting element ngokomgaqo wokusebenza. I-thermistors zezona zisetyenziswa kakhulu kwi-thermistors. Xa i-thermistor iphantsi kwemitha ye-infrared, ubushushu buyanyuka, kunye nokutshintsha kokumelana (olu tshintsho lunokuba lukhulu okanye lube luncinci, kuba i-thermistor inokwahlulwa ibe yi-coefficient ye-coefficient thermistor kunye ne-coefficient ye-coefficient thermistor engalunganga), enokuthi iguqulwe ibe yimveliso yombane. ngesekethe yokuguqula. Izinto zokufumanisa i-Photoelectric zisetyenziswa ngokuqhelekileyo njengezinto ze-photosensitive, eziqhelekileyo zenziwe nge-lead sulfide, i-lead selenide, i-indium arsenide, i-antimony arsenide, i-mercury cadmium telluride ternary alloy, i-germanium kunye ne-silicon doped materials.
Ngokweendlela ezahlukeneyo zokusetyenzwa kunye neesekethe zokuguqula, iisenso ze-infrared zinokwahlulwa zibe yi-analog kunye nodidi lwedijithali. Isekethe yokucwangcisa umqondiso we-analog pyroelectric infrared sensor yi-tube-effect field, ngelixa i-signal processing circuit ye-digital pyroelectric infrared sensor yi-chip yedijithali.
Imisebenzi emininzi ye-sensor ye-infrared ibonakaliswe ngeendlela ezahlukeneyo zokuvumela kunye nokudityaniswa kwezinto ezintathu ezinovakalelo: inkqubo ye-optical, i-element element kunye ne-conversion circuit. Makhe sijonge kwezinye iindawo apho abenzi boluvo be-infrared benze umahluko.
Ukusetyenziswa koluvo lwe-infrared
1. Ukufunyanwa kwegesi
Umgaqo we-infrared optical sensor yegesi luhlobo olusekwe kufutshane ne-infrared spectral ekhethiweyo yokufunxa iimpawu zeemolekyuli zegesi ezahlukeneyo, ukusetyenziswa koxinzelelo lwegesi kunye nobudlelwane bokuqina bokufunxa (uLambert - umthetho oyibhili ye-Lambert Beer) ukuchonga kunye nokumisela ukuxinana kwenxalenye yegesi yegesi. isixhobo sokuva.
Izinzwa ze-infrared zingasetyenziselwa ukufumana imephu yohlalutyo lwe-infrared njengoko kubonisiwe kumzobo ongentla. Iimolekyuli ezenziwe ngama-athomu ahlukeneyo ziya kungena kwi-infrared absorption phantsi kwe-irradiation yokukhanya kwe-infrared ngexesha elifanayo, okukhokelela kutshintsho kubukhulu bokukhanya kwe-infrared. Ngokweencopho zamaza ezahlukeneyo, iintlobo zerhasi eziqulethwe kumxube zinokumiselwa.
Ngokwendawo yencopho yokufunxa enye ye-infrared, kuphela ngawaphi amaqela akhoyo kwimolekyuli yegesi anokuqinisekiswa. Ukumisela ngokuchanekileyo uhlobo lwegesi, kufuneka sijonge izikhundla zazo zonke iincopho zokufunxa kwindawo ephakathi kwe-infrared yegesi, oko kukuthi, umnwe we-infrared wegesi. Ngomfanekiso we-infrared, umxholo wegesi nganye kumxube unokuhlalutywa ngokukhawuleza.
Izinzwa zegesi ye-infrared zisetyenziswa ngokubanzi kwi-petrochemical, i-metallurgical industry, imigodi yemeko yokusebenza, ukubeka iliso kungcoliseko lomoya kunye nokufunyanwa okuhambelana nekhabhoni, ezolimo kunye namanye amashishini. Okwangoku, iilaser eziphakathi kwe-infrared ziyabiza. Ndiyakholelwa ukuba kwixesha elizayo, kunye nenani elikhulu lamashishini asebenzisa izinzwa ze-infrared ukubona igesi, izinzwa zegesi ye-infrared ziya kuba zihle kakhulu kwaye zingabizi.
2. Umlinganiselo we-Infrared Distance
I-sensor ephakathi kwe-infrared luhlobo lwesixhobo sokuvalela, kukusebenzisa i-infrared njengendlela yenkqubo yokulinganisa, uluhlu olubanzi lokulinganisa, ixesha lokuphendula elifutshane, elisetyenziswa kakhulu kwisayensi kunye nobuchwepheshe bale mihla, ukhuselo lwelizwe kunye nemimandla yezoshishino kunye nezolimo.
Isivamvo esisuka kwi-infrared sinesibini se-infrared yokudlulisa kunye nokufumana i-diode, usebenzisa i-infrared ephuma kwi-sensor ukukhupha i-beam yokukhanya kwe-infrared, ukwenza inkqubo yokubonakalisa emva kokukhanyisa into, ukubonakalisa kwi-sensor emva kokufumana umqondiso, emva koko usebenzisa i-CCD. ukusetyenzwa komfanekiso ukufumana ukusasazwa kunye nokufumana idatha yomahluko wexesha. Umgama wento ubalwa emva kokuqhutyelwa yiprosesa yesignali. Oku kungasetyenziselwa kuphela kwiindawo zendalo, kodwa nakwiipaneli ezikhanyayo. Ukulinganisa umgama, impendulo ephindaphindiweyo, ilungele iimeko ezingqongileyo zemizi-mveliso.
3. UThutho lwe-Infrared
Ukuhanjiswa kwedatha usebenzisa i-infrared sensors kukwasetyenziswa ngokubanzi. Ulawulo olukude lweTV lusebenzisa imiqondiso yosasazo ye-infrared ukulawula ukude i-TV; Iifowuni eziphathwayo zinokusasaza idatha nge-infrared transmission. Ezi zizicelo ebezikho ukusukela oko itekhnoloji ye-infrared yaqala ukuphuhliswa.
4. Umfanekiso we-Infrared Thermal
Umfanekiso weThermal sisivamvo sokwenziwa esinokuthi sibambe imitha ye-infrared ekhutshwa zizo zonke izinto ezinobushushu obungaphezulu kunoziro ngokupheleleyo. Umfanekiso oshushu waphuhliswa ekuqaleni njengesixhobo sokujonga umkhosi kunye nesixhobo sokujonga ebusuku, kodwa njengoko sasisetyenziswa ngokubanzi, ixabiso lehla, ngaloo ndlela landiswa kakhulu intsimi yesicelo. Usetyenziso lomfanekiso oshushu luquka izilwanyana, ezolimo, isakhiwo, ukubonwa kwerhasi, usetyenziso lwemizi-mveliso nomkhosi, kunye nokubhaqwa komntu, ukulandelwa kunye nokuchongwa. Kwiminyaka yakutshanje, umfanekiso we-infrared thermal usetyenziswe kwiindawo ezininzi zoluntu ukulinganisa ngokukhawuleza ukushisa kweemveliso.
5. Ukungeniswa kwe-infrared
Ukutshintshwa kwe-infrared induction iswitshi yolawulo oluzenzekelayo olusekelwe kwi-teknoloji yokungenisa i-infrared. Iqaphela umsebenzi wayo wolawulo oluzenzekelayo ngokuva ubushushu be-infrared obuphuma kwihlabathi langaphandle. Iyakwazi ukuvula ngokukhawuleza izibane, iingcango ezizenzekelayo, ii-alamu zokulwa nobusela kunye nezinye izixhobo zombane.
Ngelensi yeFresnel yenzwa ye-infrared, ukukhanya kwe-infrared okusasazekileyo okukhutshwa ngumzimba womntu kunokuvakala ngokutshintsha, ukuze kuqatshelwe imisebenzi eyahlukeneyo yolawulo oluzenzekelayo njengokukhanyisa isibane. Kwiminyaka yakutshanje, ngokuthandwa kwekhaya elihlakaniphile, i-infrared sensing iye yasetyenziswa kwiitoti zenkunkuma ezikrelekrele, izindlu zangasese ezikrelekrele, izitshixo ezikrelekrele, iingcango zokungeniswa kunye nezinye iimveliso ezikrelekrele. Uluvo lwe-infrared alukho nje malunga nokubona abantu, kodwa luhlaziywa rhoqo ukuze kuphunyezwe imisebenzi emininzi.
Ukuqukumbela
Kwiminyaka yakutshanje, ishishini le-Intanethi leZinto liphuhliswe ngokukhawuleza kwaye linethemba elibanzi lokuthengisa. Kulo mongo, imakethi ye-infrared sensor iye yakhula ngakumbi. Ke ngoko, isikali saseTshayina se-infrared detector siyaqhubeka nokukhula. Ngokwedatha, ngo-2019, ubungakanani bemakethi ye-infrared ye-infrared yaseTshayina ephantse ibe yi-400 yezigidi zeeyuan, ngo-2020 okanye phantse i-500 yezigidi zeeyuan. Idityaniswe nemfuno yokulinganisa ubushushu be-infrared yobhubhane kunye nokungathathi hlangothi kwekhabhoni yokuchongwa kwerhasi ye-infrared, ubungakanani bentengiso yeenzwa ze-infrared buya kuba bukhulu kwixesha elizayo.
