Fiber optic kub sensor, Intelligent soj ntsuam system, Distributed fiber optic chaw tsim tshuaj paus nyob rau hauv Suav teb
Fiber optic tsis yog tsuas yog siv rau kev sib txuas lus teeb liab kis tau tus mob, tab sis kuj rau kev hnov thiab pom ntau yam ntawm lub cev, suav nrog acceleration, siab, kub, lwm. Vim lub fact tias optical fibers lawv tus kheej tsis xav tau lub hwj chim mov thiab tsis cuam tshuam los ntawm electromagnetic cuam tshuam, Kev co optical fibers tau dhau los ua dav siv hauv cov ntawv loj hauv ib puag ncig. Ib qho system tuaj yeem ua tiav kev tshawb pom txij li kaum ntawm metres mus rau kaum mais, uas muaj qhov pom tseeb zoo dua li niaj hnub nrhiav kom pom cov kab ke (kev vibration cables, cov kab xau, lwm.).
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm fiber ntau optic kev vibration ntsuas yog tsim kom muaj kev cuam tshuam ntawm lub teeb los ntawm sab nraud (vibration los yog compression), thiab ntes cov teeb liab cuam tshuam kom ua tiav qhov kev kuaj pom. Muaj ob txoj hauv kev tseem ceeb kom tau txais kev cuam tshuam kho qhov muag: siv ob txoj kev ywj pheej optical fibers los xa cov homologous monochromatic lub teeb thiab thaum kawg coupling kom ua tiav qhov cuam tshuam kho qhov muag, feem ntau hu ua Mach Zehnder cuam tshuam; Lwm hom yog inter hom cuam tshuam hauv multimode fibers.
Fiber optic vibration sensors tau siv dav hauv kev tiv thaiv thiab ceeb toom ntxov ntawm qhov siab thiab qhov chaw siab tshaj vim lawv qhov zoo xws li tsis muaj hluav taws xob cuam tshuam., tsis xav tau kev siv fais fab ntawm qhov chaw, zoo mus ntev kev cia siab thiab stability, thiab kis tau tus mob ntev. Kev phom sij ntawm pob zeb thiab pob zeb poob ceeb toom kev soj ntsuam yog ib ceg ntawm kev tiv thaiv txoj kab nqes siab thiab ntxhab.. Yog hais tias txaus ntshai pob zeb thiab rockfall yuav raug kuaj ua ntej, nws yuav zoo heev txo cov kev poob nyiaj txiag los ntawm cov pob zeb txaus ntshai thiab pob zeb poob rau kev tsheb ciav hlau, txoj kev loj, lwm. Fiber optic vibration sensing technology yog ib hom kev siv tshuab uas hloov cov yam ntxwv ntawm lub teeb xa mus rau hauv fiber ntau optic sensor thaum nws cuam tshuam los ntawm kev cuam tshuam sab nraud.. Los ntawm cov cuab yeej ntsuas tshwj xeeb, cov teeb liab tau sau thiab txheeb xyuas kom pom cov kev hloov pauv ntawm cov yam ntxwv ntawm lub teeb, yog li no nrhiav kev vibration ntawm cov khoom.
Cov yam ntxwv ntawm fiber optic kev co sensors
Cov yam ntxwv ntawm fiber ntau optic sensors yog qhov sib kis tau ntev thiab tiv thaiv kev cuam tshuam ntawm electromagnetic. Lawv tau siv dav, thiab lawv cov ntaub ntawv hloov kho feem ntau suav nrog kev siv zog siv, fiber optic grating, thiab cuam tshuam. Tam sim no, muaj ntau patented technologies nyob rau hauv lub tshav pob ntawm fiber optic vibration sensors. Cov fiber ntau optic sensors muaj lawv tus kheej zoo, qee qhov muaj rhiab heev, qee qhov muaj cov lus teb zoo, thiab qee qhov muaj cov ntsiab lus technical siab, uas tuaj yeem hloov kho tau zoo rau kev hloov pauv kev vibration teeb liab. Nrog rau kev txhim kho txuas ntxiv ntawm kev hnov cov thev naus laus zis, tib neeg txoj kev xav tau rau sensors kuj nce. Muaj kev xav tau ntau ntxiv rau fiber ntau optic vibration sensors uas ua tau raws li cov xwm txheej ntawm kev xav tau siab, tus nqi qis, txheej txheem npaj yooj yim, thiab zoo stability. Nyob rau hauv tus txheej txheem ntawm kev hnov thiab nrhiav pom, rhiab heev thiab stability yog lub ntsiab technical influencing yam, thaum cov txheej txheem npaj thiab tus nqi yog qhov tseem ceeb cuam tshuam rau hauv kev tsim khoom. Vibration sensors uas muab cov txiaj ntsig zoo no tau txais kev nyiam thiab nyiam.
Lub vibration fiber optic sensor muaj cov qauv yooj yim, siab rhiab heev, loj tso zis amplitude, muaj zog tiv thaiv kev cuam tshuam, ntev kis tau tus mob, zoo low-frequency teb, qis qis qis zaus, loj dynamic ntau ntawm lub diaphragm, thiab zoo damping nyhuv. Nws tuaj yeem hloov kho tau zoo rau qee lub sijhawm tshwj xeeb xws li qhov siab-siab chimney co, low-frequency vibration ntawm cov choj, kev soj ntsuam ntawm cov av nkos precursors, thiab mus sij hawm ntev tsawg-zaus vibration teeb liab xyuas nyob rau hauv complex ib puag ncig tej yam kev mob xws li av qeeg precursor infrasound tsis.
Qhov zoo ntawm Fiber Optic Vibration Sensor Detection System
1. Ib puag ncig tsis zoo tsis cuam tshuam
Lub sij hawm ntev installation nyob rau hauv hnyav sab nraum ib puag ncig uas tsis muaj leej twg ntawm lub luag haujlwm, ruaj khov sensor qauv, thiab siab qaug zog lub neej;
2. Muaj zog tiv thaiv kev cuam tshuam
Ntxiv rau cov teeb liab tshwm sim los ntawm cov pob zeb ntog, vibration signals kuj muaj ntau cov teeb meem cuam tshuam nrog kev txheeb xyuas muaj zog;
3. Fiber optic sensors muaj cov lus teb ceev ceev
Kev saib xyuas raws txoj kev tsheb ciav hlau yog dav, thiab txhawm rau txuag cov nqi thiab nce kev soj ntsuam ntau ntawm cov sensors, siab sensor rhiab heev yog yuav tsum tau.
4. Tsis cuam tshuam los ntawm lwm yam kev vibrations
Nyob rau tib lub sij hawm raws li siab rhiab heev, nws muaj lub zog txaus los tiv thaiv kev puas tsuaj los ntawm kev co loj los ntawm cov tsheb ciav hlau.
