Txij li thaum nws pib, optical fiber ntau qhov kub thiab txias sensors tau siv dav hauv cov tshuab hluav taws xob, kev tsim kho, tshuaj engineering, aerospace, kev kho mob thiab kev tsim kho dej hiav txwv thiab lwm yam kev lag luam, thiab tau ua tiav ntau daim ntawv thov kev ntseeg siab. Tus kws kho yav dhau los kuj tau qhia nws daim ntawv thov hauv ob thaj chaw ntawm geophysics thiab choj engineering. Hauv cov ntsiab lus hauv qab no, tus editor yuav qhia koj txog daim ntawv thov ntawm optical fiber kub sensors hauv lwm qhov chaw.
1. Optical fiber kub sensors muaj cov ntawv thov tseem ceeb hauv cov tshuab fais fab. Qhov kub thiab txias ntawm lub hwj chim cables thiab qhov ntsuas kub ntawm qhov ntom ntom -kab kab hluav taws xob; kev saib xyuas cov cua sov- qhov chaw nyob hauv siab - cov khoom siv hluav taws xob faib hluav taws xob; ambient kub nrhiav thiab hluav taws kub tswb systems nyob rau hauv fais fab nroj tsuag thiab substations; Kev ntsuas qhov kub thiab txias, kev tiv thaiv thermal thiab kev kuaj mob ntawm ntau yam loj thiab nruab nrab- cov tshuab hluav taws xob loj, hloov pauv, thiab lub cev muaj zog; qhov ntsuas kub thiab qhov ua txhaum ntawm qhov ntsuas cua sov, cov kav dej hauv cov kav dej, thiab cov kav dej hauv cov roj hluav taws xob hauv thermal fais fab nroj tsuag; geothermal fais fab nroj tsuag thiab sab hauv tsev enclosures Khoom ntsuas kub ntawm substations, thiab lwm yam.
2. Optical fiber kub sensor, tshwj xeeb tshaj yog fiber ntau grating kub sensor, yog ib qho yooj yim rau embedded nyob rau hauv cov khoom los ntsuas qhov kub thiab txias nyob rau hauv cov kev daws teeb meem thiab loj ntau yam, yog li nws yog dav siv nyob rau hauv lub tsev thiab txuas hniav. Qee lub tebchaws tsim kho xws li Tebchaws Meskas, United Kingdom, Nyiv, Canada, thiab Lub Tebchaws Yelemees tau ua tiav kev tshawb fawb txog kev saib xyuas kev nyab xeeb ntawm choj, thiab tau teeb tsa kev saib xyuas kev nyab xeeb ntawm choj thiab kev ceeb toom ntxov ntawm cov choj loj los saib xyuas tus choj tseem ceeb, kev kub ceev. , thiab kev khiav tawm. Kev nyab xeeb ntsuas. Thaum lub caij ntuj sov xyoo 1999, 120 fiber ntau Bragg grating kub sensors tau teeb tsa rau ntawm tus choj steel qauv ntawm Las Cruces Interstate 10 hauv New Mexico, Tebchaws Asmeskas, teeb tsa cov ntaub ntawv rau feem ntau siv cov sensors ntawm ib tus choj.
3. Kev lag luam aerospace yog qhov chaw uas cov sensors siv ntau heev. Txhawm rau saib xyuas lub siab, qhov kub thiab txias, kev vibration, roj theem, tsaws iav xwm txheej, tis thiab rudder txoj haujlwm, thiab lwm yam, lub dav hlau yuav tsum siv ntau tshaj 100 sensors. Yog li ntawd, qhov loj thiab qhov hnyav ntawm lub sensor ua qhov tseem ceeb heev. Los ntawm qhov zoo ntawm qhov me me thiab lub teeb yuag, optical fiber ntau sensors tsis tuaj yeem piv nrog lwm cov sensors.
4. Qhov me me ntawm lub sensor yog qhov tseem ceeb hauv kev siv kho mob. Fiber grating sensors yog qhov tsawg tshaj plaws sensors muaj hnub no. Fiber Bragg Grating Sensors tuaj yeem ntsuas kev ua haujlwm ntawm tib neeg cov ntaub so ntswg nrog kev puas tsuaj tsawg, thiab muab cov ntaub ntawv tseeb hauv zos txog qhov kub, siab, thiab acoustic yoj teb. Fiber Bragg Grating Sensors yog nplua nuj nyob rau hauv kev siv tshuab rau tib neeg cov ntaub so ntswg. Kev tshawb fawb ntawm optical fiber kub sensors suav txog ze li 20 feem pua ntawm tag nrho cov kev tshawb fawb ntawm optical fiber sensors.
Ntxiv rau qhov kev txheeb xyuas qhov chaw, kev txhim kho thiab kev txhim kho ntawm cov khoom siv uas twb muaj lawm, kev tshawb fawb ntawm optical fiber kub sensors tam sim no muaj cov hauv qab no txoj kev loj hlob: vigorously txhim kho cov cuab yeej ntsuas rau ntsuas kub tis, uas yog, los ntawm kev ntsuas qhov kub ntawm ib qho taw tes rau. ntsuas qhov ntsuas kub raws li cov khoom siv fiber ntau Kev ntsuas kub thiab ntsuas qhov kub ntawm qhov chaw faib khoom ntawm thaj chaw loj; kev txhim kho ntawm ntau-functional sensors nrog rau ntsuas kub; kev loj hlob ntawm loj - nplai sensor arrays kom paub tag nrho - optical telemetry.
