Ib qho kev piav qhia ntawm kev tshawb fawb ntawm txoj kev ntawm tus kheej-calibration yuam kev misalignment ntawm infrared ntsuas kub
Nrog rau txoj kev loj hlob ntawm cov cuab yeej niaj hnub no, tus pas ntsuas kub infrared tau siv dav hauv kev tshuaj xyuas kab hluav taws xob, kev saib xyuas thiab kev ua haujlwm ntawm lub substation, hauv kev ua haujlwm thiab kev them nqi kom pom cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cables, hluav taws xob connectors thiab lwm yam kub tsis xws luag, thiab nrhiav hluav taws xob. khoom siv tsis raug. Kev siv cov ntsuas kub infrared ua haujlwm tau zoo, cuam tshuam ncaj qha rau kev ua haujlwm ruaj khov ntawm daim phiaj hluav taws xob. Txhawm rau txhim kho kev ua haujlwm zoo, txhawm rau ua kom muaj kev nyab xeeb, tus pas ntsuas kub infrared yuav tsum tau ua txij li kev ua haujlwm calibration los xyuas kom meej tias kev ua haujlwm ntawm lub ntsuas kub infrared nyob rau hauv kev ua haujlwm zoo.
1 dub lub cev hluav taws xob thiab infrared ntsuas kub ntsuas txoj cai
Txhua qhov kub siab tshaj xoom degrees ntawm cov khoom yog tas li xa tawm lub zog hluav taws xob infrared mus rau qhov chaw nyob ib puag ncig. Qhov loj ntawm cov khoom siv hluav taws xob hluav taws xob hluav taws xob thiab nws qhov kev faib tawm los ntawm wavelength thiab nws qhov kub thiab txias ntawm qhov chaw muaj kev sib raug zoo heev, yog li ntawd, los ntawm kev ntsuas lub zog infrared radiated los ntawm cov khoom nws tus kheej, tus pas ntsuas kub qhov muag qhov system hauv lub ntes mus rau hauv lub teeb liab hluav taws xob thiab los ntawm tus pas ntsuas kub infrared tso saib ib feem ntawm qhov ntsuas kub ntawm qhov khoom yuav tsum ntsuas, nws yuav muaj peev xwm txiav txim siab qhov kub thiab txias ntawm qhov chaw, uas yog lub hauv paus ntawm infrared radiation thermometry Lub Hom Phiaj hauv paus.
Infrared tus pas ntsuas kub nta: ntsuas tsis sib cuag, qhov kub ntau, lub sij hawm teb ceev ceev, siab rhiab heev, tab sis vim qhov cuam tshuam ntawm emissivity ntawm cov khoom nyob rau hauv kev sim, nws yuav luag tsis yooj yim sua kom ntsuas qhov kub ntawm qhov khoom nyob rau hauv kev sim, ntsuas yog qhov kub thiab txias.
Tus txheej txheem calibration rau infrared ntsuas kub yog siv lub blackbody rauv calibration. Blackbody yog txhais nyob rau hauv txhua rooj plaub ntawm tag nrho cov wavelengths ntawm qhov teeb meem hluav taws xob nqus tus nqi yog sib npaug zos rau 1 ntawm cov khoom, lub blackbody yog ib tug zoo tagnrho qauv ntawm cov khoom, yog li cov kev taw qhia ntawm ib tug hluav taws xob coefficient nrog rau qhov xwm ntawm cov khoom thiab lub xeev ntawm cov khoom. nto kev hloov pauv, piv txwv li, emissivity, uas txhais tau tias yog cov khoom tiag tiag thiab tib qhov kub ntawm lub cev hluav taws xob hluav taws xob ntawm qhov sib piv. Cov khoom hluav taws xob thiab kev nqus ntawm infrared radiation txoj cai kom ua tau raws li Kirchhoff txoj cai lij choj, thaum lub teeb hluav taws xob tau teeb tsa rau saum npoo ntawm txhua yam khoom, raws li lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob, cov khoom ntawm qhov teeb meem hluav taws xob nqus qhov nqus, qhov cuam tshuam, kev xa tawm thiab cov txiaj ntsig ntawm qhov peb yuav tsum sib npaug rau 1, qhov dav dav emissivity tsis yooj yim rau kev txiav txim, feem ntau yog los ntawm kev ntsuas ntawm qhov nqus nqus los txiav txim siab qhov emissivity, yog li lub blackbody qhov chaw ntawm hluav taws xob raws li cov qauv hluav taws xob rau kev txiav txim siab ntawm ntau qhov chaw ntawm infrared. hluav taws xob Radiation siv.
Infrared tus pas ntsuas kub los ntawm qhov system optical, photodetector, teeb liab amplifier thiab teeb liab ua, tso zis tso zis thiab lwm yam khoom. Cov khoom ntsuas thiab qhov cuam tshuam ntawm qhov chaw ntawm cov kab hluav taws xob los ntawm cov khoom siv hluav taws xob demodulation nkag mus rau lub ntsuas hluav taws xob infrared. Qhov sib txawv ntawm ob lub teeb liab yog amplified los ntawm inverse amplifier thiab tswj qhov kub thiab txias ntawm lub tswv yim qhov chaw, kom lub spectral radiation brightness ntawm lub tswv yim qhov chaw yog tib yam li lub spectral radiation brightness ntawm cov khoom. Cov zaub qhia qhov ci ntsa iab ntawm qhov khoom raug ntsuas. Infrared ntsuas kub ntsuas los ntawm cov khoom hluav taws xob kub ntau dua li qhov ntsuas kub ntawm qhov khoom, vim tias lub cev dub tsis muaj nyob, ntawm tib qhov ntsuas kub hauv cov khoom siv hluav taws xob tiag tiag yog ib txwm tsawg dua li tag nrho cov hluav taws xob hluav taws xob los ntawm lub cev dub, yog li qhov ntsuas kub infrared ntsuas los ntawm cov khoom yuav tsum yeej tsawg dua qhov ntsuas kub tiag tiag. Kev ntsuas kub yuav tsum nyob deb li deb tau los teeb tsa lub ntsuas kub infrared emissivity (rau qhov kho tau emissivity ntawm lub ntsuas kub infrared) rau hauv tib tus nqi emissivity ntawm emissivity ntawm cov khoom yuav tsum tau ntsuas, kom deb li deb tau los ua qhov ntsuas ntawm tus nqi. ntawm qhov ntsuas kub tiag tiag ntawm qhov khoom yuav tsum ntsuas.
Infrared tus pas ntsuas kub tam sim no tau siv dav, tau dhau los ua cov cuab yeej tseem ceeb rau kev kuaj xyuas cov khoom siv hluav taws xob. Raws li kev siv lub sij hawm ntev hauv cov kab ntau lawm, kev ntsuam xyuas ntawm qhov chaw ntawm cov chaw nres tsheb, cov khoom siv hluav taws xob hluav taws xob sib txuas, T-hom hlau clips, los ntawm cov phab ntsa casing pob qij txha, cov tsheb npav, cov riam rooj tog txiav, cable txuas; Cov kab sib txuas, xaim txuas lub raj, xaim clips lossis xaim txuas. Vim qhov kev siv tsis zoo ntawm ib puag ncig thiab kev saib xyuas niaj hnub tuaj yeem ua rau kev ua haujlwm ntawm lub ntsuas kub infrared tsis tuaj yeem ntsuas qhov tseeb lossis txawm tias cov khoom siv tsis ua haujlwm, ua rau kev ntsuas tsis raug, cuam tshuam rau kev ua haujlwm ruaj khov ntawm daim phiaj hluav taws xob. Nyob rau hauv daim ntawv no, raws li lub hauv paus ntsiab lus ntawm infrared kub ntsuas nyob rau hauv lub lag luam ntawm infrared tus pas ntsuas kub nws tus kheej-calibration txoj kev, yooj yim thiab yooj yim mus use, kev siv cov units yuav ua tau raws li cov qauv no ntawm tus kheej-calibration khoom, nyob rau hauv lub teb ua ntej lub kev ntsuam xyuas ntawm tus pas ntsuas kub infrared nws tus kheej-calibration piv, los txiav txim seb lub ntsuas kub infrared puas nyob rau hauv lub xeev ntawm kev ua haujlwm zoo, koj tuaj yeem ua tiav qhov kev sim ua haujlwm, txhawm rau txo qhov kev pheej hmoo ntawm kev nyab xeeb.
