Haus luam yeeb Ntes: hom, yam ntxwv, cog

Niaj hnub no, tsis siv neeg tua hluav taws tswb installation yog yuav tsum tau engineering systems ntawm tej lub tsev. Lawv ua yuam kev-free lag luam yog tsis tsuas cov kev nyab xeeb ntawm vaj tse, tab sis kuj, tseem ceeb tshaj, tus noj qab haus huv thiab lub neej ntawm cov neeg. Raws sij hawm thiab yog hluav taws kub kom paub tias enables neeg kom khiav tawm mus rau ib tug muaj kev ruaj ntseg hauv cheeb tsam, thiab hluav taws txib - mus pib kom sai extinguishing hluav taws, kev tiv thaiv nws kis.

hom detectors

Hluav Taws detectors raws li ib feem ntawm ib tug tsis siv hluav taws tswb system tsim los ntes cov hluav taws. Nyob rau hauv lub khiav hauj lwm hauv paus ntsiab lus, lawv muab faib ua ntau hom. Lawv yog:

• Haus luam yeeb Ntes - teb mus rau lub tsos ntawm cov pa luam yeeb nyob rau hauv lub chav tsev;
• thermal sensor - yog txhais tias thaum ib tug predetermined kub yog ua zoo tshaj;
• nplaim taws ntes - captures ib tug pom los yog infrared tawg ntawm cov nplaim taws;
• analyzer - sau combustion cov khoom xws li carbon monoxide.

Qhov tseeb xaiv ntawm lub ntes tso cai rau hauv thaum ntxov nrhiav kom tau ntawm qhov hluav taws kub chaw.

Hluav Taws load thiab lub hom ntes

Txawv chav muaj lawv tus kheej tseem nyob rau hauv txoj kev loj hlob ntawm cov hluav taws thiab lub manifestation ntawm nws yam. Tseem ceeb heev hluav taws load - tag nrho cov khoom thiab cov ntaub ntawv nyob rau hauv lub chav tsev. Piv txwv li, inks los yog hluav taws kub nrog kaj nplaim taws roj, uas tej zaum yuav tau muab sau los ntawm tus ntes nplaim taws. Tab sis tib lub nplaim taws ntes yuav tsis tau zoo nyob rau hauv cov chav nrog cia ntaub ntawv uas yog cov nquag mus kev noj nyiaj txiag, haus luam yeeb los ntawm smoldering ntaub ntawv li cas pa hluav taws.

pa luam yeeb detectors

Feem ntau thiab txhais tau tias zoo rau automatic hluav taws nrhiav kom tau cov pa luam yeeb ntes. Vim hais tias ntawm cov pa luam yeeb combustion txheej txheem cov yam ntxwv ntawm ntau yam, xws li ntawv, ntoo, textiles, cable khoom, hluav taws xob cov khoom thiab li ntawd. Cov sensors yog tsim los ntes cov hluav taws kub uas muaj pa luam yeeb emission nyob rau hauv thaum ntxov ua sawv ntawm ib tug tua hluav taws. Detectors ntawm no hom yog zoo nyob rau hauv ib tug pej xeem lub tsev, pej xeem vaj tse, storehouses, industrial thiab rooj ntaub ntawv nws haus luam yeeb emission thaum lub sij hawm combustion.

Lub hauv paus ntsiab lus ntawm cov lag luam ntawm pa luam yeeb detectors

Lub lag luam ntawm lub flue sensor yog lub teeb scattering rau microparticles haus luam yeeb. Lub emitter ntawm lub sensor, feem ntau LED, kev khiav hauj lwm nyob rau hauv lub kho qhov muag los yog infrared ntau yam. Nws irradiates cov huab cua nyob rau hauv cov pa luam yeeb chamber, cov pa luam yeeb blanketing ib feem ntawm lub teeb thaws rov los los ntawm cov pa luam yeeb hais thiab yog ua li khiav ri. Qhov no ua li khiav ri tawg yog kaw nyob rau photodetector. Ib tug microprocessor raws li rau tsom ntawm lub teeb liab ntawm qhov photodetector translates ntes nyob rau hauv ib tug tswb mob. Nyob rau hauv lub concentration emitter thiab receiver tej zaum yuav taw tes detectors thiab linear. Cov npe ntawm pab kiag li lawm ntawm no hom pib nrog "SP 212", ua raws li los ntawm cov zauv qauv ntawv. Cov tsab ntawv los sawv rau "hluav taws ntes", tus thawj naj npawb 2 - "Haus luam yeeb", cov xov tooj 12 - "kho qhov muag". Yog li, tag nrho cov npav "SP 212" qhia :. "Haus luam yeeb ntes kho qhov muag"

Spot pa hluav taws

Nyob rau hauv pab kiag li lawm ntawm no hom emitter thiab receiver yog mounted nyob rau hauv ib tsev nyob rau ob tog ntawm cov pa luam yeeb chamber. Perforation ntawm lub sensor tsev nyob muaj unhindered allergic ntawm haus luam yeeb rau hauv cov pa luam yeeb chamber. Yog li, Haus luam yeeb ntes opto-hluav taws xob ntsuas pa hluav taws tsom kwm lub chav tsev nyob rau ib tug taw tes. Sensors ntawm no hom yog compact, yooj yim rau nruab thiab efficiency. Lawv lub ntsiab disadvantage - tag xyuas cheeb tsam tsis tshaj 80 sq.m Nyob rau hauv feem ntau tus neeg mob, taw tes detectors ntsia rau lub qab nthab, nyob rau hauv increments, nyob ntawm seb lub qhov siab ntawm lub chav tsev. Tab sis nws yog ua tau rau nruab rau lawv nyob rau hauv lub phab ntsa, nyob rau hauv lub qab nthab.

Tawm Haus luam yeeb Detectors

Nyob rau hauv cov sensors, lub transmitter thiab receiver yog cais pab kiag li lawm ntsia ntawm txawv sab ntawm lub chav tsev. Yog li, lub emitter beam kis tau los ntawm lub chav tsev thiab lwm yam uas cov pa luam yeeb. Feem ntau, lub ntau yam ntawm kev txiav txim ntawm no hom ntawm ntes yog tsis ntau tshaj li 150 m. Muaj cov variations ntawm pab kiag li lawm nyob rau hauv uas lub emitter thiab receiver yog mounted nyob rau hauv tib lub tsev thiab lawv kho qhov muag axes yog qhia nyob rau hauv tib txoj kev coj. Yuav kom siv xws li ib tug ntes yog siv ib tug ntxiv Reflector (reflectors), mounted rau cov opposite phab ntsa thiab rov beam transmitter mus rau lub receiver. Tawm pa hluav taws no mas siv los tiv thaiv nws kim heev thiab siab rau tej qhov chaw, xws li halls, sab hauv tsev arenas, lub qhov. Lawv yog mounted rau ntawm phab ntsa nyob rau hauv lub qab nthab, radiator rau ib phab ntsa, lub receiver nyob rau lwm yam. Nyob rau hauv high school chav, xws li cov atria, ob peb sensors yog mounted nyob rau hauv tiers.

Lub rhiab heev ntawm lub sensor

Qhov tseem ceeb tshaj parameter ntawm pa luam yeeb detectors yog lawv rhiab heev. Nws characterizes lub peev xwm ntawm lub sensor mus ntes tus yam tsawg kawg nkaus concentration ntawm cov pa luam yeeb hais nyob rau hauv lub analyzed cua. Qhov no tus nqi yog ntsuas nyob rau hauv dB thiab yog nyob rau hauv lub chav 0.05-0.2 dB. Qhov sib txawv muaj nuj nqis sensors yog lub peev xwm kom muaj nws orientation thaum hloov qhov rhiab heev, mov voltage, ambient lub teeb, kub thiab lwm yam lwm yam. Mus xyuas lub photodetector siv tshwj xeeb laser pointers los yog aerosols, uas tej thaj chaw deb xyuas ntawm ntes kev kawm.

Analog thiab addressable system

Cov hluav taws tswb tshuab, detectors yog kev cob cog rua rau lub tiaj cable hluav taws tswb tswj vaj huam sib luag, uas analyzes lawv tus mob thiab nyob rau hauv cov ntaub ntawv ntawm kom ntawm ib tug tswb. Nyob rau cov qauv ntawm cov kis ntawm nws lub xeev detectors yog analog los yog chaw nyob.

Haus luam yeeb ntes yog kev cob cog rua rau lub analog voj nyob rau hauv thaum uas tig mus, thiab thaum twg txhais sharply thiaj li lawv tsis kam, nyob rau hauv lwm yam lus, luv luv-circuits lub voj. Qhov kev hloov no nyob rau hauv lub voj kuj thiab yog tsau los ntawm cov tswj vaj huam sib luag. Raws li ib tug txoj cai, kev twb kev txuas ntawm analog detectors yog ua ob-hlau cable, uas yog tseem nkag nrog lub hwj chim. Tab sis muaj kev xaiv rau plaub-hlau kev twb kev txuas tswvyim. Lub disadvantage ntawm no system yog cov impossibility ntawm cov tsis tu ncua saib xyuas kev kawm ntawm lub ntes, nyob rau hauv tas li ntawd, tej zaum xauv voj drawdown tsis actuated sensor.

Addressable Haus luam yeeb Ntes electro-kho qhov muag ntseg ib microprocessor uas tsom kwm rau lub xeev ntawm cov sensor thiab adjusts nws chaw yog tsim nyog. Cov sensors yog kev cob cog rua rau ib cov voj nyob rau hauv uas txhua ntes yog muab ib tug xov tooj. Nyob rau hauv xws li ib tug system rau lub tswb tswj tsev tau txais tsis tau tsuas yog lub ntes yog txhais rau cov ntaub ntawv thiab nws cov chav tsev, tab sis cov kev pab cuam cov lus qhia txog cov kev kho mob, plua tshauv thiab li ntawd.

Nyob rau hauv tus neeg mob ntawm feem ntau niaj hnub detectors muaj LEDs, lawv flashing txiav txim lawv tus mob.

Autonomous hluav taws detectors

Feem ntau, yog tsis muaj yuav tsum tau rau nruab ib automatic hluav taws tswb installation, tsuas qhia txog lub hauv paus chiv keeb ntawm qhov hluav taws kub neeg uas yog nyob rau hauv ib chav. Rau lub hom phiaj no, lub ntes yog ib tug stand-alone pa luam yeeb. Cov pab kiag li lawm muab ib tug pa luam yeeb sensor thiab ib tug sounder (tsib rov). Thaum nyob hauv tsev haus luam yeeb ntes no haus luam yeeb thiab nws audible teeb liab qhia rau cov neeg txog lub xub ntiag ntawm yus tsi ntsees ntawm haus luam yeeb. Tej sensors yog nws tus kheej-powered - Ua-nyob rau hauv roj teeb muaj peev xwm uas yog txaus khiav rau peb lub xyoos.

Cov detectors yog zoo tagnrho rau cov installation nyob rau hauv ib tug tsev los yog lub tsev me me. Ib co ua qauv tso cai rau koj mus muab cov sensors nyob rau hauv ib tug me me network, xws li nyob rau hauv lub chav tsev. Lub cev lub ntsiab ntawm no sensor muaj ib tug LED qhov taw qhia, xim thiab zaus ntawm blinking yog tham txog nws tus mob.
