Umgaqo wenkqubo ye-alarm ye-fiber optic esasazwayo kunye nomahluko phakathi kwenkqubo yentambo yokubona ubushushu

Inzwa yobushushu bokukhanya kweFayibha, Inkqubo yokubeka iliso ekrelekrele, Kusasazwe umenzi ifayibha optic e China

Uphuhliso lweTekhnoloji yokuJonga iFiber Optic Sensor

Inkulungwane ye-21 yinkulungwane ye-photon, ngophuhliso olukhawulezayo lobuchwepheshe be-optical kunye neshishini. Itekhnoloji ye-Optical sensing yenye itekhnoloji yetekhnoloji yovavanyo lwe-elektroniki kwaye yenye yezona zinto zikhawulezayo ziphuhlisa itekhnoloji yesicelo kule minyaka ilishumi idlulileyo.. Itekhnoloji yokubona iFiber optic yindlela ebalulekileyo yobuchule yokuthintela ingozi kunye nokubeka iliso. Ukusebenza kwayo kobugcisa kuneengenelo ezingenakuthelekiswa nanto xa kuthelekiswa neemveliso zekhebula zokubona ubushushu bemveli, kwaye sele isetyenziswa ngokupheleleyo kumashishini awahlukeneyo ehlabathini lonke. Ngokuqondwa ngakumbi kweenzuzo zobuchwepheshe, iya kuthatha indawo ngokubanzi iinkqubo zezivamvo zombane.

Umgaqo we i-fiber optic cable esweni inkqubo yokujonga ubushushu

Iqondo lobushushu lelona xabiso lomzimba libalulekileyo nelisisiseko ekumiseleni ukuba intambo isebenza kakuhle na. Ngokubeka esweni ubushushu beentambo, iintambo zentambo, iitheminali zentambo, njl., iimpazamo ezinokwenzeka okanye eziqhubekayo kwiintambo zinokuqikelelwa okanye zibonwe ngexesha elifanelekileyo, ukuthintela ngempumelelo iingozi zentambo ukuba zenzeke
Ngokuqhelekileyo kukho iindidi ezimbini zomlilo wentambo, oko kukuthi imithombo yomlilo yangaphakathi kunye nemithombo yomlilo yangaphandle. Imithombo yomlilo yangaphakathi ibhekisa ikakhulu kwizinto ezinjengokugcwala ngokugqithisileyo komsinga wothumelo lwentambo, i-impedance ephezulu kwiintambo zentambo, ukuguga kwesikhumba se-insulation, okanye ukukhutshwa kwenxalenye yentambo ngokwayo, nto leyo ebangela ukunyuka kobushushu kumphezulu wentambo. Umaleko we-insulation kunye nokhuseleko lwentambo kwakhona uvelisa ukutshaya, ehamba kunye nokuveliswa kobushushu obukhulu kunye neegesi ezivuthayo. Njengoko ubushushu bunyuka, Umsi uyaveliswa, okukhokelela kuphuhliso lomlilo. Imithombo yomlilo yangaphandle ibhekiselele kwindawo apho ikhebula ikhona okanye enye imithombo yomlilo ngaphakathi kwe-cable interlayer, ngokunjalo nemithombo eyahlukeneyo yomlilo yangaphandle. Imithombo yangaphandle yomlilo inokubangela ukuba umphezulu wentambo ubambe umlilo, ngelixa uvelisa inani elikhulu lobushushu kunye nomsi. Kwiintambo eziqhelekileyo, Isixhobo se-sheath sikhupha ngokubanzi umlinganiselo othile werhasi enokutsha xa ubushushu bungaphezu kwe-150C, kwaye akukho msi uveliswayo ngeli xesha; Uluhlu lweqondo lokushisa lwe-270C luya kukhulula inani elikhulu leegesi ezinokutsha kunye nomsi, equlethe iigesi eziyityhefu. Xa ubushushu bungaphezu kwama-270C, ikwixesha elingazinzanga ngokugqithisileyo kwaye inokutsha nangaliphi na ixesha. Ukutshisa okuzenzekelayo, iqondo lobushushu linokufuna ukufikelela phantse kuma-390C phambi kokuba litshise. Nangona kunjalo, iintlekele ezibangelwa yimithombo yomlilo yangaphandle, iya kutshisa phambi kwesixa esikhulu segesi evuthayo. Ngeentambo ezinqanda amadangatye okanye ezinqanda amadangatye, Imililo yentambo yomlilo erhoxisa amadangatye isenokwenzeka. Ngokungafaniyo neentambo eziqhelekileyo, iqondo lobushushu lokuzitshisa linyuke laya kutsho kuma-480C, kwaye ngaphezu kwe-190C, umlinganiselo othile werhasi etshayo uveliswayo, kodwa akukho msi uveliswayo; Yenza isixa esikhulu serhasi etshayo kwi-270C. Ngoko ke, iimpazamo zentambo kuqala zivelisa ubushushu obukhulu, kunye ne-fiber optic esasaziweyo yeqondo lobushushu elihambelana nenkqubo yokubona umlilo ijonga utshintsho kwindawo engqongileyo yobushushu ngexesha lokwenyani., ukuze ikwazi ukucacisa ngokuchanekileyo ukuba kukho naziphi na izinto ezingaqhelekanga kwikhebula kumanqanaba okuqala eengozi, ukuphumeza amanyathelo okuthintela.

Umahluko phakathi kwenkqubo ye-alarm ye-fiber optic esasaziweyo kunye nenkqubo yentambo yokubona ubushushu

Inkqubo ye-alarm ye-fiber optic esasaziweyo yinkqubo yokubeka iliso echanekileyo enokuthi ibeke iliso ixesha lokwenyani lobushushu bendawo nganye ecaleni kwentambo yefiber optic.. Iindlela ze-alam ezifana ne-avareji yobushushu zinokuseta ngokulula iindlela ze-alam kunye namaxabiso kwindawo nganye. Kwimeko yomlilo, ayinayo kuphela umsebenzi wezixhobo ze-alam zemveli zokugweba ngengozi kunye ne-alamu yengingqi, kodwa inokuphinda ifumane kwaye isete ubushushu bendawo ye-alam. Ukwengeza, ngokubonisa ubushushu bexesha lokwenyani, indlela yophuhliso yeengozi zomlilo inokugwetywa ngokuchanekileyo, ukubonelela ngesiseko sedatha yokucima umlilo. Ulwazi oluchanekileyo. Ikhuselekile kwaye inokuthenjwa | ayichatshazelwa luphazamiseko lwe-electromagnetic kunye nakuphi na okusingqongileyo, ukhuselekile ngokwendalo, zilungele iimeko ezinobungozi obukhethekileyo, kudityaniswe ne-alamu rhoqo kunye nokwahluka kweqondo lokushisa, ngokupheleleyo akukho zilumkiso zobuxoki. Ukusebenzisa i-tensile resistant, ukumelana nefuthe, i-diameter encinci yangaphandle, kunye neentambo zamehlo eziguquguqukayo, ukufakela kunqunyanyiswe kumgca othe ngqo, elunge kakhulu kwaye ayifuni ukunxibelelana ngokusondeleyo nentambo. Ayichaphazeli ukufakela kunye nokuguqulwa kwexesha elizayo kwentambo, ngokunjalo nokubeka iliso kumgama omde. Intambo enye ye-optical inokugqiba ukuchongwa kunye nokuhanjiswa kwesignali, kwaye zonke iisetingi zigqityiwe kwi-terminal. Yonke inkqubo ilula, ethembekileyo, kunye nesondlo sasimahla ubomi bonke. Ubomi benkonzo bugqithise 30 iminyaka. Ukususela kwiindleko zokulondolozwa kunye nobomi benkonzo yenkqubo, ukusebenza kweendleko ze-fiber optic fire alarm systems inkulu kakhulu kuneemveliso zentambo zokuva ubushushu. Inkqubo yefiber optic inokwamkela ngokuguquguqukayo iinkqubo ezinemigama eyahlukeneyo kunye namanani amatshaneli ngokwemiqathango yokusetyenziswa kwendawo.;
