Ntau tus neeg xaiv lub koob yees duab zais los saib xyuas lawv lub tsev, chaw ua haujlwm, lossis lub tsheb discreetly. Ib qho kev teeb tsa feem ntau yog tso lub koob yees duab sab hauv, taw qhia nws tawm ntawm lub qhov rais lossis iav nto. Tab sis nws puas ua tau tiag tiag? Cov lus teb luv luv yog yog - cov koob yees duab zais tuaj yeem sau los ntawm iav - tab sis cov txiaj ntsig nyob ntawm qhov teeb pom kev zoo thiab ob peb txoj kev xaiv yooj yim.
Hauv tsab xov xwm no, peb yuav piav qhia tias yog vim li cas koj thiaj li khiav mus rau hauv cov teeb meem (tshwj xeeb yog hmo ntuj), yuav ua li cas kom tau txais cov duab meej hnub thiab hmo ntuj, thiab hom koob yees duab zais dab tsi ua tau zoo tshaj plaws hauv cov xwm txheej no.
Vim li cas iav tuaj yeem ua teeb meem rau cov koob yees duab zais
Iav cia pom lub teeb hla tau yooj yim, yog li kev kaw hnub nruab hnub feem ntau yog ntse thiab meej. Qhov kev sib tw tiag tiag tuaj thaum hmo ntuj thaum lub koob yees duab zais feem ntau hloov mus rau infrared (IR) pom kev hmo ntuj.
Nov yog qhov tshwm sim:
- Lub koob yees duab ua tau -hauv IR LEDs emit infrared teeb pom kev kom "teeb" qhov chaw.
- Thaum lub teeb no tsoo lub iav, ntau ntawm nws pom ncaj nraim rov qab rau hauv lub lens.
- Qhov tshwm sim? Lub ci ntsa iab, qhov muag plooj ntawm lub koob yees duab nws tus kheej lossis chav tom qab nws, tsis yog qhov pom sab nraud.
Qhov no IR bounce yog tus lej-ib qho laj thawj tib neeg xav tias lawv lub koob yees duab zais "tsis ua haujlwm los ntawm iav."
Nruab hnub kaw los ntawm iav: Feem ntau tsis muaj teeb meem
Thaum nruab hnub, lub teeb ntuj lossis chav teeb hla lub iav tsis muaj teeb meem loj. Feem ntau koj yuav tau txais cov yeeb yaj kiab meej ntev npaum li:

Tswv yim: Tilt lub koob yees duab me ntsis (5–10 degrees) kom txo qis kev cuam tshuam los ntawm lub teeb sab hauv tsev.
Hmo ntuj kaw: Yuav ua li cas kho qhov teeb meem IR Reflection
Nov yog txoj hauv kev zoo tshaj plaws kom tau txais cov duab hmo ntuj siv tau los ntawm iav:
1. Tshem tawm qhov tsim ua - hauv IR hmo ntuj pom kev
Qhov no nres qhov teeb meem kev xav tam sim ntawd. Lub koob yees duab yuav cia siab rau lub teeb pom kev zoo (txoj kev teeb, teeb lub teeb, thiab lwm yam) hloov.
2. Muab lub lens kom ze li sai tau rau lub khob
Siv lub tshuab nqus dej- khob mount lossis nplaum nplaum los nias lub lens sab xis ntawm lub qhov rais. Tsawg qhov sib txawv ntawm huab cua=tsawg dua kev xav.
3. Ntxiv cov teeb pom kev zoo sab nraud
Ib qho kev taw qhia - qhib lub teeb lub teeb, hnub ci vaj teeb, lossis txawm tias lub teeb pom kev sab nraum zoov IR tuaj yeem muab lub teeb yam tsis tau thaws tawm ntawm lub khob.
4. Xaiv lub teeb qis- lossis"tsis muaj -glow"zais lub koob yees duab
Cov qauv no siv siab - sensors rhiab heev los sau cov xim nrog lub teeb me ntsis thiab tsis tawm pom lossis cuam tshuam IR.
5. Lub koob yees duab me ntsis
Ib qho me me qaij tuaj yeem txav qhov kev xav tawm ntawm lub lens txoj kab ncaj nraim ntawm qhov pom.
