Puas yog tus pas ntsuas kub infrared ntsuas qhov ntsuas kub ntawm cov khoom tom qab iav yog qhov tseeb?
Nws tuaj yeem ntsuas qhov ntsuas kub ntawm cov khoom tom qab iav, thiab tseem tuaj yeem ntsuas qhov ntsuas kub ntawm lub iav nto. Tus yuam sij yog teem lub wavelength txais ntawm tus pas ntsuas kub. Vim hais tias tus pas ntsuas kub ntsuas qhov ntsuas kub ntawm cov khoom raws li cov hluav taws xob siv hluav taws xob ntawm qee qhov wavelength ntawm cov khoom kub. Txhawm rau ntsuas qhov ntsuas kub los ntawm iav, qhov tau txais wavelength ntawm tus pas ntsuas kub yuav tsum tau hloov mus rau 1.2 ~ 2.0 microns. Txhawm rau ntsuas qhov kub ntawm lub khob nws tus kheej, qhov tau txais wavelength ntawm tus pas ntsuas kub yuav tsum tau hloov mus rau 5.0~ 7.5 microns. Yuav ua li cas kho lub wavelength? Lub wavelength ntawm qee qhov ntsuas kub yog lub Hoobkas teeb, thiab qee qhov tau muab ntau yam rau koj xaiv thaum koj siv nws. Tsuas yog thaij duab ntawm * bao, thiab nco ntsoov tias nws muaj ntau yam spectral ntawm 8 ~ 14 microns:
Vim li cas thiaj xaiv cov wavelengths sib txawv los hloov los ntsuas qhov kub ntawm lub khob nws tus kheej lossis qhov kub ntawm cov khoom tom qab iav? Qhov no nyob ntawm qhov kev xa tawm ntawm iav (saib daim duab hauv qab). Hauv qhov luv-yoj ntau yam (0.2 microns txog 2 microns), lub iav yuav luag 100 feem pua Ib puas pob tshab. Hauv lwm lo lus, cov ntsuas kub infrared tuaj yeem "pom" cov khoom kub los ntawm iav. Tab sis nyob rau hauv qhov ntev-yoj ntau yam (ntau dua 4 microns), qhov kev xa ntawm iav yog yuav luag 0. Lub sijhawm no, lub iav yog sib npaug rau lub cib thaiv cov khoom qab nws. Yog tias koj siv lub ntsuas hluav taws xob infrared los ntsuas qhov ntsuas kub ntawm lub khob, koj tuaj yeem ntsuas qhov kub ntawm lub khob xwb.
Thaum lub tsheb khiav, lub log tsheb bearings yuav kub hnyiab vim kev sib txhuam ntawm cov neeg kho tshuab. Thaum cov bearings nyob rau hauv qhov zoo, nws yog ib txwm rau qhov kub thiab txias nce mus rau ib qho twg. Thaum qhov kub thiab txias nce txawv txav, nws txhais tau hais tias lub zog ntawm cov kabmob yog deteriorating, kev sib txhuam thiab hnav hnyav, lubrication zoo yog txo, thiab cov kabmob yog tawg thiab deformed. Hauv qhov xwm txheej hnyav dua, nws yuav ua rau lub tsheb ciav hlau txiav lub qag thiab hlawv lub qag kev sib tsoo. Lub cim ntawm thermal axis phenomenon undoubtedly coj zoo tej zaum yuav muaj kev ruaj ntseg txaus ntshai rau railway tsheb kev nyab xeeb. Txhawm rau kom tsis txhob muaj kev phom sij zais cia los ntawm qhov tshwm sim no rau kev tsav tsheb kev nyab xeeb, tib neeg tau mob siab rau lawv tus kheej rau kev tshawb fawb ntawm qhov ntsuas kub ntawm lub qag rau ntau xyoo. Lub infrared ncej kub nrhiav kom tau qhov system yog ib qho ntawm cov tsis sib cuag ncej kub nrhiav kom tau txoj kev tsim los ntawm tib neeg.
Ncej kub hauv online nrhiav kom tau cov khoom saum toj kawg nkaus xoom muaj hluav taws xob hluav taws xob sib txuas nrog qhov kub thiab txias, thiab cov hluav taws xob siv hluav taws xob nce ntxiv nrog qhov nce ntawm qhov kub thiab txias, thiab cov hluav taws xob peak wavelength hloov mus rau qhov kev taw qhia yoj luv. Tag nrho lub zog hluav taws xob tawm los ntawm qhov chaw ntawm lub cev dub kiag yog proportional rau plaub lub zog ntawm nws qhov kub thiab txias T, thiab qhov ntsuas kub tuaj yeem tau los ntawm kev kuaj xyuas lub zog hluav taws xob. Thaum qhov kub thiab txias yog ntau pua mus rau phav phav degrees, cov hluav taws xob spectrum feem ntau yog nyob rau hauv lub infrared band. Yog li ntawd, qhov kub ntawm cov khoom tuaj yeem tau txais los ntawm kev kuaj xyuas lub zog radiant nyob rau hauv ib qho tshwj xeeb infrared band. Cov cuab yeej ua los ntawm kev siv lub hauv paus ntsiab lus no yog cov khoom siv hluav taws xob infrared ntsuas kub.
Raws li lub hauv paus ntawm kev ua haujlwm ntawm kev ntsuas qhov ntsuas kub ntawm lub qag (tsuas yog ntsuas qag thiab cov kabmob kub), nws tseem tuaj yeem hloov kho lub kaum sab xis ntawm lub sensor kom pom lub log ntawm qhov kub thiab txias tib lub sijhawm. Thaum lub tsheb hla, nws ntsuas qhov ntsuas kub ntawm lub log tsheb mus rau lub npoo kom tiv thaiv cov log kub uas tshwm sim los ntawm kev nres khau khau lossis lwm yam laj thawj. Tus ncej kub yog quantitatively forecasted raws li peb-theem tswb ntsuas kub me ntsis, muaj zog cua sov thiab huab cua kub, thiab cov ntaub ntawv tswb.
