Qhov kev ruaj ntseg tshiab kawg tso cai rau koj txuag khoom thiab tib neeg txoj sia. Ntau tus ntawm lawv siv lub tswb nrov. Nws yog ib qho tsim nyog los xyuas qhov hluav taws kub thaum ntxov thiab muab lub teeb liab. Lub kaw lus muaj ntau yam khoom siv, suav nrog lub ntsuas pa taws. Txhawm rau kom cov cuab yeej ua haujlwm tau zoo, koj yuav tsum xaiv cov cuab yeej no kom raug.
Txoj kev xav
Smoke detector - ib lub cuab yeej siv los txiav txim qhov chaw ntawm hluav taws. Thaum lub sijhawm ua haujlwm ntawm lub cuab yeej, qhov nqus tau raug tshuaj xyuas, nrog rau kev ua haujlwm tawg hauv ib qho ntawm cov spectra:
- ultrasonic;
- infrared;
- pom.

Raws li txoj kev tshawb nrhiav qhov chaw ntawm qhov hluav taws kub, cov khoom siv yog cov xov tooj cua isotope, uas saib xyuas cov ntaub ntawv ntawm lub koob yees duab radioisotope, thiab optoelectronic, uas teeb hluav taws los ntawm kev hloov pauv huab cua thiab qhov ci ntawm lub teeb.
Muaj lwm tusdetectors - aspiration. Cov cuab yeej tau nthuav tawm raws li ib qho khoom siv tus kheej, uas muaj laser thiab point optical sensors. Cov cuab yeej sau npe cov cim thaum ntxov ntawm hluav taws. Lawv raug kho rau hauv qhov chaw nyuaj mus txog, tsev cia puav pheej thiab ntawm nkoj.
Raws li txoj kev tshawb pom lub cev, lub ntsuas pa taws tuaj yeem yog:
- smoke;
- firemen;
- fiery.
Tsab tswb hluav taws tuaj yeem ua ke nrog cov pa taws teb. Thaum nws txo qis, qhov kev ceeb toom raug muab tua. Cov no yog cov khoom siv nquag. Tab sis kuj muaj cov passive uas muab lub teeb liab los ntawm cov pa luam yeeb. Lub roj teeb ua hluav taws xob ntsuas hluav taws xob pom tau tias yooj yim siv.
siv thaj chaw
Lub tshuab ntsuas pa taws tuaj yeem kuaj pom qhov xwm txheej hluav taws kub thaum pib tshwm sim. Tom qab tag nrho, cov pa luam yeeb yog tsim ua ntej, thiab tom qab ntawd tua hluav taws. Lub sijhawm ua haujlwm ntawm lub cuab yeej tso cai rau tib neeg khiav tawm.
Cov khoom siv tuaj yeem ntsia tau rau hauv cov chav uas tsim hluav taws kub thaum pib qhia pom tias muaj pa taws. Tab sis koj yuav tsum coj mus rau hauv tus account ntuj cuam tshuam - high humidity thiab pa luam yeeb. Nrog rau cov xwm txheej no, kev ua haujlwm tsis raug ntawm cov cuab yeej tshwm sim, nrog rau lawv qhov kev puas tsuaj.
Hauv cov tsev nyob, cov khoom siv kho qhov muag feem ntau txuas nrog. Yog hais tias qhov chaw ntawm chav tsev yog voluminous, ces qhov tsim nyog optical linear pab kiag li lawm yog hom chaw nyob. Hauv cov tsev kawm tseem ceeb tshwj xeeb, optical aspiration annunciators raug teeb tsa, uas ua haujlwm sai heev. Qhov tseem ceeb yog qhov ceev ntawm cov khoom siv. Tom qab tag nrho, kev nyab xeeb ntawm tib neeg thiab kev nyab xeeb ntawm cov khoom nyob ntawm qhov no.
Qhov zoo thiab qhov tsis zoo
Hluav taws tua hluav taws muaj nws qhov zoo thiab qhov tsis zoo. Feem ntau, ntau hom khoom siv tau nruab rau hauv tib chav, uas tuaj yeem ceeb toom koj txog ntau yam tsis zoo. Ntawm lub tsev sensors, optoelectronic sawv daws yuav suav hais tias nrov tshaj plaws. Cov txiaj ntsig suav nrog:
- tawm tsam sai thaum hluav taws;
- nplua nuj assortment;
- tus nqi pheej yig;
- yam tsawg kawg nkaus rau nruab.
Los ntawm qhov tsis txaus tuaj yeem txheeb pom:
- siv ntau tam sim no;
- plua plav teb;
- tsis muaj tshuaj tiv thaiv combustion yam tsis muaj pa taws.
khoom manufacturers
Khw muag khoom ntau yam ntawm lub tswb nrov. Raws li txoj kev ua, lawv yog:
- kho qhov muag;
- linear;
- ionization.
Cov khoom siv kho qhov muag pom tau tias yog cov khoom siv nrov tshaj plaws, tab sis lawv muaj qhov tsis zoo: lawv hnov mob rau plua plav, tab sis tsis muaj qhov cuam tshuam rau cov pa luam yeeb nrog cov dej tsis huv. Xws li cov cuab yeej ntes tau tsim los ntawm cov tuam txhab Lavxias - "Signal" thiab "IRSET-Center". Lawv muaj qhov zoo sib xws thiab qhov sib txawv.
"IRSET-Center" cov khoom siv tau tsim nrog ntau qhov hluav taws xob loj. Lawv tuaj yeem muaj me ntsis tam sim no hauv hom standby. Cov yam ntxwv yog tsim nyog rau kev ua haujlwm nrog kev txais tos thiab tswj cov khoom siv. Los ntawm cov tuam txhab txawv teb chaws, Cov khoom siv Sensor yog nyob rau hauv kev thov.
Device
ceeb toom pa taws tuaj yeem raug tsom thiab tsis yog hom phiaj. Qhov no yog txiav txim los ntawm cov txheej txheem ntawm kev sib txuas rau qhov hluav taws kub system. Yog li ntawd, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov pa taws sensor txawv. Chaw nyob cov cuab yeej xa cov teeb liab mus rau lub vaj huam sib luag tswj, qhov chaw tua hluav taws tau tsim, txij li txhua yam khoom siv hauv qhov system muaj nws tus lej. Lawv siv rau hauv qhov chaw loj, chaw tsim khoom.
Cov khoom siv tsis yog chaw nyob ua suab nrov, thiab koj tuaj yeem txiav txim siab thaj tsam ntawm qhov hluav taws kub los ntawm nws. Optoelectronic fire alarm khoom muaj xws li cov ntaub ntawv yas, qhov twg muaj lub koob yees duab kho qhov muag, lub teeb receiver thiab refractive shutters. Cua nkag mus rau hauv lub chamber qhia txog hluav taws xob los ntawm lub teeb qhov chaw. Thaum cov pa luam yeeb tshwm, lub tswb tshwm sim. Ua tsaug rau refractive shutters, cov cuab yeej tiv thaiv los ntawm lub teeb thiab hmoov av. Cov cuab yeej yuav tsum tau so tsis tu ncua kom tsis txhob txo qhov rhiab ntawm lub ntes.
Cov khoom siv kho qhov muag tuaj yeem muaj LED lossis laser lub teeb emitters. Cov khoom siv ionizing tau nthuav tawm nyob rau hauv daim ntawv ntawm lub chamber nrog 2 daim hlau nyob hauv qab tam sim no. Yog tias cov pa taws nkag mus rau sab hauv, lub tswb yuav tshwm sim.
Kev xaiv
Yuav kom lub tswb hluav taws ua haujlwm kom raug, nws yog qhov yuav tsum tau xaiv cov khoom kom raug rau nws. Nws yog ib qho tseem ceeb uas nws:
- kuaj pom hluav taws raws sijhawm;
- yog ntseeg;
- tsis tau qhia cuav.
Lub tshuab hluav taws xob hluav taws xob tuaj yeem siv rau hauv cov chaw uas hluav taws kub tshwm sim nrog kev tsim cov pa taws, vim tias qhov kev txiav tximraws li kev muab lub teeb liab thaum nws cov concentration nyob rau hauv cov huab cua yog tshaj. Thaum xaiv, ib tug yuav tsum coj mus rau hauv tus account lub nuances ntawm lub tsev, qhov tshwj xeeb ntawm chav tsev thiab tus nqi ntawm cov cuab yeej.
Nws raug nquahu kom yuav cov khoom siv zoo, txawm tias nws kim heev. Cov khoom zoo li no muaj los ntawm cov tuam txhab paub zoo. Thiab yog tias koj muaj kev tsis ntseeg txog kev xaiv cov cuab yeej, ces koj yuav tsum nrhiav kev pab los ntawm tus kws tshaj lij.
