Mugihe cyinyuma yicyorezo, twizera ko sensor ya infragre ari ngombwa buri munsi. Muburyo bwo kugenda, dukeneye kunyura mubipimo by'ubushyuhe inshuro nyinshi mbere yuko tugera aho tujya. Nubushyuhe bwo gupima hamwe numubare munini wa infragre sensor, mubyukuri, hari uruhare runini rwingenzi. Ibikurikira, reka turebe neza kuri sensor ya infragre.
Intangiriro kuri Infrared Sensors
Ikintu cyose kiri hejuru ya zeru (-273 ° C) gihora gisohora ingufu za infragre mumwanya ukikije, nukuvuga. Na sensor ya infragre, irashobora kumva ingufu za infragre yikintu ikayihindura mubice byamashanyarazi. Rukuruzi ya Infrared igizwe na sisitemu ya optique, kumenya ibintu hamwe no kuzenguruka.
Sisitemu ya optique irashobora kugabanwa muburyo bwo kohereza no kwerekana ubwoko ukurikije imiterere itandukanye. Ihererekanyabubasha risaba ibice bibiri, kimwe cyanduza infragre ikindi cyakira infragre. Kuruhande, kurundi ruhande, rukeneye sensor imwe gusa kugirango ikusanye amakuru yifuzwa.
Ikintu cyo gutahura gishobora kugabanywamo ibice byerekana ubushyuhe hamwe nubushakashatsi bwerekana amafoto ukurikije ihame ryakazi. Thermistors nizo zikoreshwa cyane. Iyo thermistor ikorewe imirasire ya infragre, ubushyuhe buriyongera, kandi impinduka zirwanya (iri hinduka rishobora kuba rinini cyangwa rito, kubera ko thermistor ishobora kugabanywamo ubushyuhe bwiza bwa coefficient thermistor hamwe nubushyuhe bubi bwa coefficient thermistor), bishobora guhinduka mubisohoka byamashanyarazi. binyuze mumuzunguruko. Ibikoresho byerekana amafoto bikoreshwa cyane nkibintu bifotora, mubisanzwe bikozwe muri sisitemu sulfide, gurş selenide, indium arsenide, antimoni arsenide, mercure cadmium telluride ternary alloy, germanium na silicon doped ibikoresho.
Ukurikije ibimenyetso bitandukanye byo gutunganya no guhinduranya ibintu, ibyuma bifata ibyuma bifata ibyuma bishobora kugabanywa muburyo bwa digitale. Inzira yo gutunganya ibimenyetso bya analog pyroelectric infrared sensor ni umuyoboro-ngirakamaro, mugihe ibimenyetso byo gutunganya ibimenyetso bya digitale pyroelectric infrared sensor ni chip ya digitale.
Imikorere myinshi ya infragre sensor igerwaho binyuze muburyo butandukanye hamwe no guhuza ibice bitatu byoroshye: sisitemu ya optique, ibintu byo gutahura no guhinduranya ibintu. Reka turebe ahandi hantu aho sensor ya infragre yakoze itandukaniro.
Ikoreshwa rya Infrared Sensor
1. Kumenya gaze
Ihame rya optique ya optique ya sensor ya gazi ni ubwoko bushingiye hafi ya infragre sprifalifike yo gutoranya ibintu biranga molekile zitandukanye, gukoresha ingufu za gaze hamwe nubusabane bwimbaraga (Lambert - bill Lambert Beer law) kugirango hamenyekane kandi hamenyekane ingufu za gaze yibigize gaze igikoresho.
Rukuruzi ya infragre irashobora gukoreshwa kugirango ubone ikarita yisesengura rya infragre nkuko bigaragara ku gishushanyo kiri hejuru. Molekile igizwe na atome zitandukanye zizajya zinjizwa na infragre munsi yumucyo wumucyo wa infragre kumurongo umwe, bikavamo impinduka muburemere bwurumuri. Ukurikije impinga zitandukanye, ubwoko bwa gaze burimo imvange burashobora kugenwa.
Ukurikije umwanya wikigereranyo kimwe cyo kwinjiza infragre, gusa amatsinda abaho muri molekile ya gaze arashobora kugenwa. Kugirango tumenye neza ubwoko bwa gaze, dukeneye kureba aho impinga zose zinjirira mu karere ka hagati ya infragre ya gazi, ni ukuvuga urutoki rwa gazi ya infragre. Hamwe na infragre sprifike, ibiri muri buri gaze muruvange birashobora gusesengurwa vuba.
Ibyuma bifata ibyuma bitagira ingano bikoreshwa cyane mu nganda zikomoka kuri peteroli, mu bucukuzi bw'amabuye y'agaciro, mu bucukuzi bw'amabuye y'agaciro, kugenzura ihumana ry’ikirere no kutangiza imyuka ya karubone, ubuhinzi n'izindi nganda. Kugeza ubu, lazeri yo hagati ya infragre irazimvye. Nizera ko mu gihe kiri imbere, hamwe n’inganda nyinshi zikoresha ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma,
2. Igipimo cya intera itagira ingano
Infrared ranging sensor ni ubwoko bwibikoresho byunvikana, ni ugukoresha infragre nkuburyo bwa sisitemu yo gupima, intera yagutse, igihe gito cyo gusubiza, ikoreshwa cyane cyane mubumenyi nubuhanga bugezweho, kurinda igihugu hamwe ninganda n’ubuhinzi.
Infrared ranging sensor ifite ibice bibiri byerekana ibimenyetso byogukwirakwiza no kwakira diode, ukoresheje sensor ya infragre ya sensor kugirango utange urumuri rwumucyo utagira urumuri, rukora inzira yo gutekereza nyuma yo kurasa kubintu, bikagaragarira kuri sensor nyuma yo kwakira ikimenyetso, hanyuma ugakoresha CCD gutunganya amashusho yakira kohereza no kwakira igihe cyo gutandukanya amakuru. Intera yikintu kibarwa nyuma yo gutunganywa nibimenyetso bitunganya. Ibi ntibishobora gukoreshwa gusa hejuru yimiterere karemano, ariko no muburyo bwerekana. Gupima intera, inshuro nyinshi igisubizo, kibereye ibidukikije bikaze.
3. Ihererekanyabubasha
Kohereza amakuru ukoresheje sensor ya infragre nayo ikoreshwa cyane. Kugenzura kure ya TV ikoresha ibimenyetso byogukwirakwiza infragre kugirango igenzure kure TV; Terefone zigendanwa zirashobora kohereza amakuru binyuze mumashanyarazi. Izi ni porogaramu zabayeho kuva tekinoroji ya infragre yatunganijwe bwa mbere.
4. Ishusho Yubushyuhe
Thermal imager ni sensor ya pasiporo ishobora gufata imirasire ya infragre itangwa nibintu byose ubushyuhe buri hejuru ya zeru. Imashusho yumuriro yabanje gutunganywa nkigikoresho cyo kugenzura igisirikare nigikoresho cyo kureba nijoro, ariko uko cyakoreshejwe cyane, igiciro cyaragabanutse, bityo cyaguka cyane murwego rwo gusaba. Amashusho yerekana amashusho arimo inyamaswa, ubuhinzi, inyubako, gutahura gaze, inganda n’igisirikare, hamwe no gutahura abantu, gukurikirana no kumenya. Mu myaka yashize, ishusho yubushyuhe bwa infragre yakoreshejwe ahantu henshi hahurira abantu gupima vuba ubushyuhe bwibicuruzwa.
5. Kwinjiza Infrared
Infrared induction switch ni uburyo bwo kugenzura bwikora bushingiye ku buhanga bwa infrared induction. Imenya imikorere yayo yo kugenzura byikora mukumva ubushyuhe bwa infragre ziva hanze. Irashobora gufungura vuba amatara, inzugi zikoresha, impuruza zo kurwanya ubujura nibindi bikoresho byamashanyarazi.
Binyuze mumurongo wa Fresnel ya sensor ya infragre, urumuri rutatanye rutangwa numubiri wumuntu rushobora kumvikana na switch, kugirango tumenye imirimo itandukanye yo kugenzura byikora nko gucana itara. Mu myaka yashize, hamwe no gukundwa kwurugo rwubwenge, infraring sensing nayo yakoreshejwe mubikoresho byimyanda yubwenge, ubwiherero bwubwenge, guhinduranya ibimenyetso byubwenge, inzugi zinjira nibindi bicuruzwa byubwenge. Infrared sensing ntabwo ari ukumva abantu gusa, ahubwo ihora ivugururwa kugirango igere kubikorwa byinshi.
Umwanzuro
Mu myaka yashize, inganda za interineti yibintu byateye imbere byihuse kandi bifite isoko ryagutse. Ni muri urwo rwego, isoko rya infragre sensor nayo yagiye itera imbere. Kubera iyo mpamvu, igipimo cy’isoko ry’imashanyarazi ya Chine gikomeje kwiyongera. Nk’uko imibare ibigaragaza, mu mwaka wa 2019, Ubushinwa bwifashishije isoko rya infrarafarike ingana na miliyoni 400, mu 2020 cyangwa hafi miliyoni 500. Hamwe no gukenera gupima ubushyuhe bwa infragre yo gupima icyorezo no kutabogama kwa karubone kugirango hamenyekane gaze ya infragre, ingano yisoko rya sensor ya infragre izaba nini mugihe kizaza.
