Qhov zoo ntawm Distributed Temperature Sensing
Qhov zoo ntawm Distributed Temperature Sensing
Fiber optic sensors siv lub teeb ua cov ntaub ntawv thiab fiber optics ua qhov nruab nrab rau kev xa cov ntaub ntawv. Piv nrog rau cov kev ntsuas kub ib txwm muaj, kev ntsuas qhov ntsuas kub ntawm fiber ntau muaj qhov zoo hauv qab no:
● Tsis muaj electromagnetic cuam tshuam, corrosion kuj
● Passive saib xyuas lub sijhawm, suab rwb thaiv tsev, tawg-pov thawj
● Qhov loj me, lub teeb yuag, khoov tau
● High rhiab heev, lub neej ua haujlwm ntev
● Kev ntsuas qhov deb, kev saib xyuas yooj yim
Txoj Cai ntawm DTS
DTS (Distributed Temperature Sensing) siv cov nyhuv Raman los ntsuas qhov kub thiab txias. Lub optical laser pulse xa los ntawm fiber ntau ua rau qee lub teeb tawg ua rau muaj kev cuam tshuam rau sab transmitter, qhov twg cov ntaub ntawv raug tshuaj xyuas ntawm Raman txoj cai thiab lub sijhawm kho qhov muag tsom xam (OTDR) lub hauv paus ntsiab lus hauv cheeb tsam. Raws li lub laser pulse propagates los ntawm fiber ntau, ntau hom kev tawg yog generated, ntawm cov Raman yog rhiab heev rau qhov kub thiab txias variations, qhov kub thiab txias, siab dua qhov kev siv ntawm lub teeb reflected.
Qhov kev siv ntawm Raman tawg yog ntsuas qhov kub ntawm cov fiber ntau. Raman anti-Stokes teeb liab hloov nws amplitude ho nrog kub; Raman-Stokes teeb liab yog qhov ruaj khov.
Lumispot Tech's Pulse Laser Source Series 1550nm DTS faib qhov ntsuas kub ntsuas lub teeb yog lub teeb pom kev zoo tshwj xeeb tsim los rau kev faib cov fiber ntau optic ntsuas qhov ntsuas kub raws li cov cai Raman tawg, nrog rau sab hauv MOPA qauv kho qhov muag txoj kev tsim, optimized tsim ntawm multi-theem kho qhov muag amplification, tuaj yeem ua tiav 3kw pulse lub zog, tsis tshua muaj suab nrov, thiab lub hom phiaj ntawm kev ua haujlwm siab ceev nqaim mem tes hluav taws xob teeb liab tuaj yeem ncav cuag 10ns pulse tso zis, kho tau los ntawm software mem tes dav thiab rov ua dua. zaus, tuaj yeem siv dav hauv qhov ziab ziab fiber ntau optic ntsuas qhov system, fiber optic tivthaiv kuaj, LIDAR, pulsed fiber ntau laser thiab lwm yam.
