Rukuruzi

Ibyuma bifotora ni sensor nziza ya elegitoronike ishobora kugenzura guhinduranya byizunguruka byizunguruka kubera ihinduka ryumucyo mugitondo na mwijima (izuba rirashe nizuba rirenze). Ibyuma bifotora birashobora guhita bigenzura gufungura no gufungaLED amataraukurikije ikirere, igihe n'akarere. Mu minsi yumucyo, ingufu zikoreshwa zigabanuka mukugabanya ingufu zayo. Ugereranije no gukoresha amatara ya fluorescent, ububiko bworoshye bufite ubuso bwa metero kare 200 burashobora kugabanya gukoresha ingufu za 53% cyane, kandi ubuzima bwa serivisi ni amasaha 50000 ~ 100000. Mubisanzwe, ubuzima bwa serivisi bwamatara ya LED ni amasaha 40000; Ibara ryumucyo rirashobora kandi guhinduka muri RGB kugirango urumuri rurusheho kurangi kandi ikirere gikore neza.

Rukuruzi

Rukuruzi ya infragre ikora mukumenya infragre itangwa numubiri wumuntu. Ihame nyamukuru ni: inshuro 10 imyuka yumubiri wumuntu μ Imirasire yimirasire ya M yongerwaho na lens ya filteri ya Fresnel hanyuma igakusanyirizwa kuri pyroelectric element PIR detector. Iyo abantu bimutse, imyuka yoherezwa mumirasire yimirasire izahinduka, ibintu bizatakaza amafaranga yishyurwa, bitange ingaruka za pyroelectric kandi birekure amafaranga hanze. Rukuruzi ya infragre izahindura ihinduka ryingufu zimirasire yumurongo binyuze mumashanyarazi ya Fresnel mumashanyarazi, guhinduranya Thermoelectric. Iyo nta mubiri wumuntu ugenda ahantu hamenyekana pasifike ya pasifike, sensor ya sensor yumva ubushyuhe bwinyuma gusa. Iyo umubiri wumuntu winjiye ahantu hamenyekanye, unyuze mumurongo wa Fresnel, sensor ya pyroelectric infrared sensor yumva itandukaniro riri hagati yubushyuhe bwumubiri wumuntu nubushyuhe bwinyuma, Nyuma yikimenyetso kimaze gukusanywa, igereranwa namakuru asanzwe ari muri sisitemu yo guca imanza niba umuntu nandi masoko ya infragre yinjira ahantu hagaragara.

LED Icyerekezo Cyumucyo

Ultrasonic sensor

Ibyuma bya Ultrasonic, bisa na sensor ya infragre, byakoreshejwe cyane mugushakisha mu buryo bwikora ibintu byimuka mumyaka yashize. Rukuruzi ya ultrasonic ikoresha cyane cyane ihame rya Doppler kugirango isohore imiraba myinshi ya ultrasonic yumurongo urenze imyumvire yumubiri wumuntu binyuze muri oscillator ya kristu. Mubisanzwe, 25 ~ 40KHz umurongo watoranijwe, hanyuma module yo kugenzura ikamenya inshuro yumurongo ugaragara. Niba hari urujya n'uruza rw'ibintu muri kariya gace, umurongo wikurikiranya wikurikiranya uzahindagurika gato, ni ukuvuga ingaruka ya Doppler, kugirango ucire urubanza urujya n'uruza rw'ibintu mu mucyo, Kugirango ugenzure ibintu.

Ubushyuhe

Ubushyuhe bwa sensor NTC ikoreshwa cyane nko kurinda ubushyuhe bwaLEDamatara. Niba urumuri rwinshi rwa LED rwakoreshejwe kumatara ya LED, hagomba kwakirwa imirasire yamababa menshi ya aluminium. Bitewe n'umwanya muto w'amatara ya LED yo kumurika mu nzu, ikibazo cyo gukwirakwiza ubushyuhe kiracyari kimwe mubibazo bikomeye bya tekinike muri iki gihe.

Gukwirakwiza ubushyuhe buke bwamatara ya LED bizatuma habaho gucana hakiri kare isoko yumucyo wa LED kubera ubushyuhe bwinshi. Nyuma yo gucana itara rya LED, ubushyuhe buzakungahazwa kumutwe wamatara kubera kuzamuka kwumuyaga guhita, bizagira ingaruka kumurimo wa serivisi yo gutanga amashanyarazi. Kubwibyo, mugihe utegura amatara ya LED, NTC irashobora kuba hafi yumuriro wa aluminium hafi yumucyo wa LED kugirango ikusanye ubushyuhe bwamatara mugihe nyacyo. Iyo ubushyuhe bwa radiyo ya aluminium yikombe cyamatara kizamutse, uyu muzunguruko urashobora gukoreshwa muguhita ugabanya ibyasohotse mumasoko ahoraho kugirango akonje amatara; Iyo ubushyuhe bwa aluminiyumu yumuriro wigikombe cyamatara kizamutse kugera kumupaka wagenwe, amashanyarazi ya LED ahita azimya kugirango abone ubushyuhe burenze bwamatara. Iyo ubushyuhe bugabanutse, itara rihita ryongera.

Rukuruzi

Igikoresho cyo kugenzura amajwi kigizwe na sensor igenzura amajwi, amplifier amajwi, imiyoboro yo gutoranya imiyoboro, gutinda gufungura uruziga hamwe na thyristor igenzura. Gucira urubanza niba utangira kugenzura umuzenguruko ukurikije ibisubizo byo kugereranya amajwi, hanyuma ugashyiraho agaciro kambere ka sensor igenzura amajwi hamwe nuyobora. Ijwi rigenzura amajwi ahora agereranya ubukana bwamajwi yo hanze hamwe nagaciro kambere, kandi akohereza ikimenyetso "amajwi" mukigo gishinzwe kugenzura iyo kirenze agaciro kambere. Ijwi ryo kugenzura amajwi rikoreshwa cyane muri koridoro hamwe n’ahantu hacanwa abantu.

Microwave induction sensor

Microwave induction sensor nigikoresho cyimuka cyashizweho gishingiye kumahame yingaruka za Doppler. Itahura niba imyanya yikintu yimuka muburyo budahuza, hanyuma ikabyara imikorere ijyanye. Iyo umuntu yinjiye mukarere ka sensing hanyuma akagera kumatara akenewe, sensing switch izahita ifungura, ibikoresho byumutwaro bizatangira gukora, kandi sisitemu yo gutinda izatangira. Igihe cyose umubiri wumuntu utavuye aho wumva, ibikoresho byimizigo bizakomeza gukora. Iyo umubiri wumuntu uvuye aho wumva, sensor itangira kubara gutinda. Kurangiza gutinda, sensor ya sensor ihita ifunga kandi ibikoresho byumutwaro bihagarika gukora. Mubyukuri umutekano, byoroshye, ubwenge kandi bizigama ingufu.
