Izivamvo: iintlobo, iimpawu, isityalo

Namhlanje, oluzenzekelayo ufakelo alarm umlilo iinkqubo zobunjineli olusisinyanzelo nasiphi na isakhiwo. umsebenzi wabo imposiso-free nje kuphela ukhuseleko lwepropati, kodwa, okona kubaluleke kakhulu, impilo kunye nobomi babantu. Ubhaqo umlilo ngexesha nangokuchanekileyo kwenza abantu ukuba sibalekele kwindawo ekhuselekileyo, kwaye imiyalelo umlilo - ukuqala ngokukhawuleza zokucima umlilo, ukuthintela ukusasazeka kwayo.

iintlobo detectors

detectors umlilo njengenxalenye yenkqubo alam yomlilo oluzenzekelayo eyenzelwe ukubona umlilo. Kuxhomekeka isimiso ukusebenza, ukuba zohlulwa ngokwendidi. Zezi:

• Izivamvo - ayiphendule imbonakalo umsi egumbini;
• isivamvo thermal - into izakufunyanwa xa kukho ubushushu kwangaphambili lidlule;
• nelangatye kakutsha - ithumba a radiation ebonakalayo okanye infrared amadangatye;
• analyzer - iirejista iimveliso ukutshiswa ezifana carbon monoxide.

Ukhetho oluchanekileyo lwe kakutsha ivumela ekufumanekeni umthombo lomlilo ekuqaleni.

umthwalo yoMlilo kunye nohlobo tshin

amagumbi ezahlukeneyo babe Okukodwa zabo kuphuhliso lomlilo kunye ngokubonakala izinto zayo. umthwalo umlilo kubaluleke - zonke izinto kunye nezinto kweli gumbi. Umzekelo, inks okanye umlilo kunye amafutha idangatya eqaqambileyo, ezinokuthi zifakwe kwingxelo yi edangatyeni tshin. Kodwa efanayo nelangatye tshin akayi kuba ngempumelelo kumagumbi ngezinto zokugcina ezithandwa ekuboleni, ukutshaya ukusuka engamabhodlo izinto kusabela umsi tshin.

umsi detectors

Eyona ndlela ziqhelekileyo kwaye isebenza ngokwaneleyo ukuba Ubhaqo umlilo ezenzekelayo i tshin umsi. Ngenxa umsi inkqubo yokutsha uphawu izinto ezininzi, ezifana nephepha, iinkuni, umqhaphu, iimveliso intambo, izixhobo ze-elektroniki njalo njalo. Ezi abenzi ziyilelwe ukubhaqa umlilo ebandakanya umsi ukukhutshwa xa nisaqala umlilo. Detectors yale hlobo ezisebenza a izindlu zokuhlala, izakhiwo zoluntu, oovimba, izixhobo zoshishino kunye trafficking sinotyekelo kutshaya ukukhutshwa ngexesha komlilo.

Umgaqo yokusebenza umsi detectors

Ukusebenza woluvo ulwelo uchithachitha ukukhanya microparticles abatshayayo. Le emitter womenzi woluvo, ngokokuqhelekileyo iLED, ezisebenzayo kuluhlu enombala okanye infrared. It irradiates umoya egumbini umsi, umsi blanketing inxalenye ukukhanya kubonakala ukusuka wecuba kwaye saa. Le radiation saa kubhalwe kule photodetector. A isilawuli olusekelwe kucazululo umqondiso, photodetector liguqulelwe kakutsha ikwimeko alarm. Kuxhomekeka emitter yoxinaniso kunye uyithathayo inokuba detectors point kunye nemicwe. Amagama iingcinga olu hlobo ukuqala nge "SP 212", kulandele isiqu model lwamanani. Ukubiza ncwadi imela "tshin umlilo", inani lokuqala 2 - "Umsi", inani 12 - "enombala". Ngoko ke, lonke yokumakisha "SP 212" lithetha :. "Umsi tshin optical"

Spot izivamvo

Xa iingcinga olu hlobo emitter kunye ngumamkeli zifakwe kwi izindlu enye akumacala egumbini umsi. Perforation ye izindlu woluvo inika Ukungena ngaphandle kokuphazanyiswa yomsi kwigumbi umsi. Ngenxa yoko, Umsi tshin opto-electronic izivamvo ijongana igumbi ngenqaku elinye. Izivamvo olu hlobo zezi compact, kulula ukufaka kunye nokusebenza. Zabo Ububi - ndawo kuphela esweni elingagqithanga sq.m. 80 Kwiimeko ezininzi, kwindawo detectors ezifakwe yophahla, ngokwemizuzu, kuxhomekeke ukuphakama gumbi. Kodwa kusenokwenzeka ukuba ukuzifaka phezu kodonga, phantsi eluphahleni.

Linear detectors kutshaya

Kwezi abenzi boluvo, sixhobo kunye ngumamkeli iingcinga ezahlukeneyo zafakelwa kumacala ahlukeneyo egumbini. Ngoko ke, lo umqadi emitter udlula gumbi kwaye ulawula umsi. Ngokuqhelekileyo, uluhlu inyathelo le hlobo kakutsha ayikho ngaphezulu kwe-150 m. Kukho ukwahlukahlukana izixhobo apho emitter kunye ngumamkeli zifakwe kwi izindlu efanayo namazembe zabo optic ibhekiswe kwicala elinye. Ukusebenzisa kakutsha loo usetyenziswa kugqame ezongezelelweyo (reflectors), zixhonywe malunga kwaye ibuyisela umqadi samaza ukuya receiver. Linear izivamvo kakhulu kusetyenziswa ukukhusela kwizikhewu olubanzi phezulu, ezifana iiholo, ezinkundleni endlwini, neegalari ezo. Bona zixhonywe iindonga phantsi esilingini, radiator kwi eludongeni, umamkeli phezu kwezinye. Xa magumbi aphezulu, afana imithambo, boluvo eziliqela ziyaxhonywa kwimiqolo.

Uvakalelo wexesha elongezelelweyo lomenzi woluvo

Parameter ibalulekileyo umsi detectors na uvakalelo lwabo. It ephawula ukukwazi woluvo ukuba walithimba xi ubuncinane wecuba emoyeni zihlalutywe. Eli xabiso lulinganiselwa kwi dB yaye ke uluhlu 0.05-0.2 dB. abenzi ixabiso umahluko uyakwazi ukugcina yokuqhelaniswa yayo xa ukutshintsha onovakalelo, ubonelelo ombane, sokukhanya okukufutshane, ubushushu kunye neminye imiba yangaphandle. Ukujonga photodetector usebenzisa lathisi laser ekhethekileyo okanye ulwelo, ukuvumela esweni ekude ukusebenza tshin.

Analog nenkqubo iyaziseka

I -alam yomlilo, detectors udityanisiwe kwi panel yolawulo intambo flat alarm umlilo, leyo ukuhlalutya imeko yabo xa ukusebenza kwe-alam. Kuxhomekeka kwindlela ukudluliselwa detectors zayo karhulumente analog okanye idilesi.

Izivamvo liqhagamshelene ndzhendzheleko analog ngokunxuseneyo, yaye xa kwavusa kakhulu yehlise ukuxhathisa lwabo, ngamanye amazwi, elifutshane iziphaluka ngokwenzekayo. Olu tshintsho kwi ukuxhathisa loop kwaye elibekwa panel yolawulo. Njengoko umthetho, udibaniso lwe detectors analog luyenziwa wire-ezimbini iintambo, nto leyo nayo kunikezelwe ngombane. Kodwa kukho kukho iskim uqhagamshelo-wire ezine. Engxakini kule nkqubo nakwenzeka gqolo esweni ukusebenza tshin, ukongeza, maxa wambi itshixiwe loop kwamanzi ngaphandle woluvo actuated.

Iyaziseka izivamvo electro-enombala features a isilawuli ukuba iliso imeko woluvo kwaye ulungelelanisa izigcwangciso zayo xa kuyimfuneko. Ezi abenzi uqhagamshele ndzhendzheleko yedijithali apho kakutsha nganye unikwe inombolo. Xa nkqubo kwi iyunithi yolawulo alarm akamkeli kuphela kakutsha kubangelwa kwidatha kunye igumbi yayo, kodwa ulwazi malunga ngempilo, uthuli njalo njalo.

Kwiimeko ezininzi detectors mihla kufuneka LED, ezidanyazayo lwabo ukuqinisekisa imeko yabo.

detectors umlilo izimele

Ngokufuthi, akukho mfuneko ukufaka i ufakelo alarm lomlilo ngokuzenzekela, nje ukwazisa malunga nemvelaphi nokugxotha abantu abakulo gumbi elifanayo. Ukulungiselela le njongo, le kakutsha i stand-alone yomsi. Ezi zixhobo nganisa zincwadi Womenzi umsi kunye sounder (siren). Xa umsi endlwini kakutsha ibhaqa umsi kunye uphawu wayo oluvakalayo yazisa abantu malunga ubukho zoqhaphelo eziyingozi yomsi. abenzi boluvo ezinjalo self-piston - = Yakhelwe-amandla ebhetri apho ngokwaneleyo ukuze isebenze iminyaka emithathu.

Ezi detectors zezona ukuba ufakelo eflethini okanye kwindlu encinci. Ezinye iimodeli zikuvumela ukuba ukudibanisa abenzi boluvo kwi womnatha encinane, umz ngaphakathi endlini. Umzimba iphambili yale woluvo abe LED, umbala kunye nobungakanani ukuqhwanyazaemva uthetha ngemeko yakhe.
