Hluav taws kub yog ib qho kev puas tsuaj loj tshaj plaws hauv ntiaj teb niaj hnub no. Raws li lub Rau Hli 2019, muaj ntau txog 132,000 qhov hluav taws kub hauv Suav teb ib leeg, nrog ntau txhiab tus neeg raug mob! Thiab muaj cov ntaub ntawv qhia tias qhov nruab nrab, muaj ntau dua 10,000 hluav taws kub ib hnub hauv ntiaj teb, ua rau ntau pua tus neeg tuag. Ntxiv mus, qhov kev poob los ntawm qhov hluav taws kub tau nce ob npaug ntawm geometrically nrog lub sijhawm. Yog li ntawd, muaj kev xav tau ceev ceev rau kev tiv thaiv hluav taws xob. Raws li kev tiv thaiv tseem ceeb rau hluav taws kub sab hauv tsev, cov pa luam yeeb sensors tau siv dav, thiab lawv cov kev tshawb fawb tau dhau los ua qhov tseem ceeb ntawm kev lag luam.
Raws li cov cuab yeej cuam tshuam txog kev nyab xeeb ntawm lub neej, ntau lub teb chaws tau tshaj tawm cov kev cai lij choj uas yuav tsum muaj lub tswb ceeb toom pa taws rau hauv txhua chav. Txawm li cas los xij, txawm li cas los xij, raws li kev txheeb xyuas hluav taws ntawm NFIRS system ntawm US National Fire Administration, 60% ntawm cov neeg tseem tuag. Thaum lub tswb hluav taws xob tsis siv neeg lossis tsis tau teeb tsa, 23% ntawm cov neeg tau teeb tsa lub tswb hluav taws xob tab sis yog neeg xiam oob khab, feem ntau yuav muaj qhov cuam tshuam ntau dhau los yog lub roj teeb tsis raug hloov thiab ua rau tuag. Tsis tas li ntawd, muaj ntau yam khoom siv hluavtaws nyob rau hauv lub neej niaj hnub no, thiab lub sijhawm khiav tawm ntawm tib neeg raug txo los ntawm 83% piv rau yav dhau los, uas tseem ua rau muaj kev sib tw ntau dua rau cov cim tshiab ntawm cov pa luam yeeb.
Cov pa luam yeeb thev naus laus zis hloov pauv, cov ncauj lus kom ntxaws txog qhov zoo thiab qhov tsis zoo ntawm ob tiam ntawm kev siv tshuab
Niaj hnub no cov pa luam yeeb sensing feem ntau yog siv ob lub thev naus laus zis tshawb pom -photoelectric thiab ionization technologies. Cov khoom siv ionization ib txwm siv cov khoom siv hluav taws xob americium 241 (Am241), uas siv cov hluav taws xob tawg mus rau ionize cov khoom hauv huab cua. Nws yog muab tso rau hauv lub teb hluav taws xob los ntsuas qhov tam sim no ntawm cov electrodes. Thaum cov pa luam yeeb nkag mus rau hauv ionization chamber, qhov tam sim no cuam tshuam thiab muaj lub tswb nrov. Qhov zoo ntawm cov cuab yeej no yog qhov zoo heev ntawm kev kuaj xyuas cov khoom me me, tab sis kuj tseem muaj qhov tsis zoo uas tsis tuaj yeem tsis quav ntsej. Qhov ntawd yog, kev siv cov khoom siv hluav taws xob ua rau muaj kuab paug ib puag ncig. Txawm hais tias kev siv cov txheej txheem muaj kev nyab xeeb, nws zoo heev hauv kev tsim khoom, khaws cia thiab pov tseg. nyuaj. Tsis tas li ntawd, cov koom haum cuam tshuam tau ua qhov kev ntsuam xyuas ywj pheej ntawm plaub lub tshuab hluav taws xob ion pa luam yeeb nyob rau hauv kev ua lag luam thiab pom tias cov khoom siv hluav taws xob ion pa luam yeeb tsuas tuaj yeem ceeb toom thaum muaj nplaim taws, thiab lub tswb ua haujlwm rau kev kub hnyiab thiab smoldering tsis zoo heev.
