Lub nplaim hluav taws xob kuaj pom cov pa luam yeeb thiab tso tawm cov cua sov thaum cov khoom siv hluav taws xob kub hnyiab, thiab tseem ua rau pom tsis pom lub teeb hluav taws xob uas pom los yog tsis nyob hauv qhov chaw.
Flame detectors, tseem hu ua photosensitive fire detectors, yog cov khoom siv hluav taws xob uas teb rau hluav taws, uas yog, lub tshuab hluav taws xob uas kuaj pom qhov siv ntawm cov nplaim taws thiab qhov flashing zaus ntawm cov nplaim taws.
Raws li cov yam ntxwv ntawm cov nplaim taws, muaj peb hom nplaim taws ntes: ib qho yog lub ntsuas hluav taws xob ultraviolet rhiab rau lub luv luv wavelength ultraviolet hluav taws xob hauv nplaim taws; lwm yam yog ib qho infrared rhiab heev rau qhov ntev wavelength infrared tawg nyob rau hauv nplaim taws. Tus ntes; qhov thib peb yog ib qho ultraviolet / infrared hybrid detector uas ib txhij kuaj pom luv luv- wavelength ultraviolet rays thiab ntev-wavelength infrared rays nyob rau hauv cov nplaim taws.
Raws li kev tshawb nrhiav band, nws tuaj yeem muab faib ua: ib leeg ultraviolet, ib qho infrared, ob chav infrared, triple infrared, infrared / ultraviolet, ntxiv video thiab lwm yam nplaim taws ntes.
Raws li hom tawg-pov thawj, nws tuaj yeem muab faib ua: hom tawg-pov thawj, hom kev nyab xeeb intrinsically.
Rau lub teeb ultraviolet ntawm {{0}}.185 ~ 0.260 micron wavelength generated nyob rau hauv cov nplaim taws, cov khoom siv tuaj yeem siv los ua cov khoom rhiab heev, xws li silicon carbide lossis aluminium nitrate, los yog lub raj xa dej tuaj yeem ua tau. siv los ua ib qho rhiab heev, xws li Geiger-Millet raj.
Rau lub teeb infrared ntawm 2.5 ~ 3 micron wavelength generated nyob rau hauv cov nplaim taws, lub sensor ntawm txhuas sulfide khoom siv tau. Rau lub teeb infrared ntawm 4.4 ~ 4.6 micron wavelength tsim los ntawm cov nplaim hluav taws, cov khoom siv lead ua selenide lossis cov khoom siv txhuas niobate tuaj yeem siv. Cov sensors sib txawv tuaj yeem xaiv raws li qhov sib txawv ntawm cov roj hluav taws xob sib txawv, thiab triple infrared (IR3) tau siv dav.
1. Lub hauv paus ntsiab lus tseem ceeb yog txhawm rau nruab lub ntsuas ntsuas ob zaug ntawm qhov siab ntawm lub hom phiaj siab tshaj plaws hauv thaj chaw tiv thaiv. Nyob rau hauv qhov kev ua tau zoo ntawm lub tshuab ntes, nws tsis tuaj yeem cuam tshuam los ntawm kev cuam tshuam, nrog rau cov ntaub ntawv pob tshab xws li iav thiab lwm qhov chaw. Nws tuaj yeem npog txhua lub hom phiaj thiab thaj chaw uas xav tau kev tiv thaiv, thiab yooj yim rau kev saib xyuas tsis tu ncua.
2. Thaum lub tshuab ntes tau teeb tsa, nws feem ntau yog inclined downward los ntawm 30-45 degree kaum sab xis, uas tuaj yeem ntsia tau rau pem hauv ntej, thiab tib lub sijhawm txo qhov muaj feem cuam tshuam ntawm daim iav nto. Qhov xwm txheej ncaj yuav tsum tau khaws cia rau txhua qhov hluav taws kub hauv qhov chaw tiv thaiv kom tsis txhob muaj kev cuam tshuam ncaj qha thiab cuam tshuam.
3. Txhawm rau kom tsis txhob pom qhov chaw tuag, lwm lub ntsuas hluav taws xob feem ntau yog ntsia rau ntawm lub ces kaum sab nraud, thiab nws kuj tuaj yeem siv rau hauv cov ntaub ntawv tsis ua haujlwm ntawm ib qho ntawm cov nplaim taws.
Cov ntsiab lus yav dhau los feem ntau suav hais tias yog thaum lub ntsuas hluav taws xob raug teeb tsa. Ntawm no, koj yuav tsum tau xyuam xim tshwj xeeb kom tsis txhob muaj qhov yuam kev ceeb toom nyob rau hauv lub khob ntsuas qhov ntsuas ntawm cov nplaim taws.
