Cov Cables Sensing
Kev Taw Qhia
Rau cov kab ke fiber ntau optical sensing, lub cable optical nws tus kheej yog lub ntsiab lus sensing, thiab "kev xa mus" thiab "kev nkag siab" tau koom ua ke. Lub cable sensor muaj ntau yam qauv ntawm cov hlau armor thiab cov khoom siv polymer sheathing. Lub cable sensor tsim tshwj xeeb tsis yog tsuas yog xa cov cua sov / deformation sab nraud sai sai, tab sis kuj tseem tiv thaiv cov fiber ntau optical hauv lub cable, uas yog qhov tsim nyog rau cov kev xav tau ntawm ntau yam kev lag luam.
Cov xov hlau kub tsis yog hlau
Cov xov hlau kub uas tsis yog hlau yog ib hom xov hlau sensor uas tsim tshwj xeeb rau qhov chaw ntsuas kub nrog lub zog hluav taws xob muaj zog thiab lub zog sib nqus muaj zog. Cov xov hlau fiber optic siv cov qauv raj nruab nrab uas tsis yog hlau, uas muaj cov raj roj PBT puv, xov aramidon thiab lub plhaub sab nraud, uas yooj yim thiab siv tau. Hom xov hlau no muaj cov khoom siv kho qhov muag zoo heev, tiv taus dej, tsis muaj hlau thiab lwm yam zoo, uas tsim nyog rau kev ntsuas kub ntawm cov xov hlau hluav taws xob siab hauv cov qhov av cable / txoj kev hauv tsev.

Hlau clad kub sensing cable
Cov xov hlau uas muaj hlau tiv thaiv kub thiab txias siv cov qauv tsim uas muaj hlau tiv thaiv ob txheej, muaj cov khoom siv tensile thiab compressive zoo. Cov xov fiber optic siv cov qauv raj nruab nrab, uas muaj cov raj PBT roj puv, cov hlau kauv, cov xov aramid, cov xov hlau braided, cov xov aramid thiab cov hnab sab nraud. Cov xov no muaj cov khoom siv optical zoo heev, tiv taus dej tau zoo, muaj zog tensile/compressive, yooj ywm zoo, siv tau rau qhov kub thiab txias dav thiab lwm yam. Tsis tas li ntawd, lub hnab sab nraud siv cov polymer thermal conductivity siab los txhim kho qhov ceev ntawm cov fiber optical rau qhov kub thiab txias sab nraud, uas tsim nyog rau kev ntsuas kub xws li cov qhov cable thiab cov kav dej roj.

Tightly packed strain sensing cable
Lub plhaub sab nraud ntawm cov xov hlau optical cable uas ntim nruj nreem yog ua los ntawm cov polymer siab, cov fiber sensing fiber txuas nrog lub plhaub sab nraud, thiab cov kev nyuaj sab nraud tuaj yeem hloov mus rau cov fiber sensing fiber sab hauv los ntawm lub tes tsho tiv thaiv. Nws muaj kev ywj pheej zoo, kev teeb tsa yooj yim, thiab lub zog tensile thiab compressive mechanical, uas yog qhov tsim nyog rau kev saib xyuas ib puag ncig sab hauv tsev lossis sab nraum zoov nrog kev pheej hmoo tsawg ntawm kev cuam tshuam sab nraud. Xws li kev saib xyuas kev sib tsoo ntawm txoj kab hluav taws xob / yeeb nkab.
Tightly packed strain sensing cable
Cov yam ntxwv ntawm cov khoom
· Raws li lub pob khoom polymer sheath siab, tuaj yeem tiv taus qhov cuam tshuam ntawm lub zog hauv qab;
· Elastic, mos, yooj yim khoov, tsis yooj yim tawg;
· Nws tuaj yeem kho tau rau ntawm qhov chaw ntawm cov khoom ntsuas hauv txoj kev nplaum, thiab nws txuas ze rau cov khoom ntsuas thiab muaj kev sib koom tes zoo deformation;
· Tiv thaiv kev xeb, rwb thaiv tsev, tiv taus kub tsawg;
· Kev tiv thaiv zoo ntawm kev hnav sab nraud.
Kev txhim kho kev ntxhov siab ntawm cov xov hlau
Cov xov hlau fiber ntau uas muaj zog tiv thaiv tau muaj ntau txheej tiv thaiv (xws li hlau tooj liab lossis hlau polymer uas muaj zog FRP), thiab cov khoom siv ntim sab nraud yog cov polymer siab. Qhov ntxiv cov khoom txhawb zog ua rau lub zog tensile thiab compressive ntawm cov xov hlau optical zoo dua, uas tsim nyog rau kev faus ncaj qha lossis kev tso cov xov hlau optical uas txuas rau saum npoo av, thiab tuaj yeem tiv taus qhov cuam tshuam suav nrog cov txheej txheem nchuav pob zeb, thiab siv dav hauv choj, kev sib tsoo ntawm qhov av, av qeeg thiab lwm yam kev soj ntsuam hnyav.
Kev txhim kho kev ntxhov siab ntawm cov xov hlau
Cov yam ntxwv ntawm cov khoom
· Raws li cov qauv zoo li cable twisted, ntau txoj hlua ntawm cov khoom siv muaj zog siab ua kom zoo dua qhov tensile thiab compressive zog ntawm cable;
· Kev hloov pauv sab nraud yooj yim hloov mus rau cov fiber ntau optical;
· Elastic, yooj yim khoov, tsis yooj yim tawg;
· Nws tuaj yeem kho tau rau hauv cov pob zeb los ntawm kev faus ncaj qha los saib xyuas qhov kev hloov pauv ntawm lub zog sab hauv ntawm cov qauv;
· Tiv thaiv corrosion, dej tsis kam, tsis kub tsawg;
