Kev Taw Qhia Txog Kev Siv Tshuab Ntsuas Photoelectric
Kev siv tshuab photoelectric nrhiav yog ib qho ntawm cov thev naus laus zis tseem ceeb ntawm kev siv tshuab photoelectric, uas feem ntau suav nrog kev hloov pauv photoelectric, kev tau txais cov ntaub ntawv kho qhov muag thiab kev ntsuas cov ntaub ntawv kho qhov muag thiab kev ua cov ntaub ntawv ntsuas photoelectric. Xws li txoj kev photoelectric kom ua tiav ntau yam kev ntsuas lub cev, kev ntsuas lub teeb tsawg, kev ntsuas lub teeb tsawg, kev ntsuas infrared, kev ntsuas lub teeb, kev ntsuas lub teeb, kev ntsuas laser, kev ntsuas fiber ntau, thiab kev ntsuas duab.
Kev siv tshuab photoelectric nrhiav kom paub ua ke cov thev naus laus zis kho qhov muag thiab cov thev naus laus zis hluav taws xob los ntsuas ntau yam, uas muaj cov yam ntxwv hauv qab no:
1. Kev ntsuas siab heev. Qhov tseeb ntawm kev ntsuas photoelectric yog qhov siab tshaj plaws ntawm txhua yam kev ntsuas. Piv txwv li, qhov tseeb ntawm kev ntsuas qhov ntev nrog laser interferometry tuaj yeem ncav cuag 0.05μm / m; Kev ntsuas lub kaum sab xis los ntawm grating moire fringe txoj kev tuaj yeem ua tiav. Qhov kev daws teeb meem ntawm kev ntsuas qhov deb ntawm lub ntiaj teb thiab lub hli los ntawm laser rangeing txoj kev tuaj yeem ncav cuag 1m.
2. Kev kub ceev. Kev ntsuas photoelectric siv lub teeb ua qhov nruab nrab, thiab lub teeb yog qhov ceev tshaj plaws ntawm txhua yam khoom, thiab nws yog qhov ceev tshaj plaws kom tau txais thiab xa cov ntaub ntawv los ntawm cov txheej txheem kho qhov muag.
3. Kev deb ntev, ntau yam. Lub teeb yog qhov yooj yim tshaj plaws rau kev tswj chaw taws teeb thiab telemetry, xws li kev taw qhia riam phom, kev taug qab photoelectric, telemetry TV thiab lwm yam.
4. Kev ntsuas tsis sib cuag. Lub teeb rau ntawm qhov khoom ntsuas tuaj yeem suav tias tsis muaj zog ntsuas, yog li tsis muaj kev sib txhuam, kev ntsuas dynamic tuaj yeem ua tiav, thiab nws yog qhov ua tau zoo tshaj plaws ntawm ntau txoj kev ntsuas.
5. Lub neej ntev. Hauv kev xav, lub teeb nthwv dej yeej tsis hnav, tsuav yog qhov rov ua dua tau zoo, nws tuaj yeem siv tau mus ib txhis.
6. Nrog rau kev ua cov ntaub ntawv thiab kev suav lej muaj zog, cov ntaub ntawv nyuaj tuaj yeem ua tiav ua ke. Txoj kev photoelectric kuj yooj yim los tswj thiab khaws cov ntaub ntawv, yooj yim ua kom tiav automation, yooj yim txuas nrog lub khoos phis tawj, thiab yooj yim ua tiav xwb.
Kev siv tshuab kuaj duab photoelectric yog ib qho thev naus laus zis tshiab uas tseem ceeb hauv kev tshawb fawb niaj hnub no, kev tsim kho tshiab hauv tebchaws thiab tib neeg lub neej, yog ib qho thev naus laus zis tshiab uas sib xyaw ua ke tshuab, teeb, hluav taws xob thiab khoos phis tawj, thiab yog ib qho ntawm cov thev naus laus zis muaj peev xwm tshaj plaws.
Qhov thib peb, cov qauv thiab cov yam ntxwv ntawm photoelectric detection system
Vim yog qhov nyuaj thiab ntau yam ntawm cov khoom sim, cov qauv ntawm lub kaw lus ntes tsis zoo ib yam. Lub kaw lus ntes hluav taws xob feem ntau muaj peb ntu: sensor, teeb liab conditioner thiab output link.
Lub sensor yog lub cuab yeej hloov pauv teeb liab ntawm qhov sib txuas ntawm cov khoom uas tau sim thiab lub kaw lus kuaj. Nws ncaj qha rho tawm cov ntaub ntawv ntsuas los ntawm cov khoom ntsuas, hnov nws qhov kev hloov pauv, thiab hloov nws mus rau hauv cov kev ntsuas hluav taws xob uas yooj yim ntsuas.
Cov teeb liab uas cov sensors ntes tau feem ntau yog cov teeb liab hluav taws xob. Nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov zis, xav tau kev hloov pauv ntxiv, kev ua tiav thiab kev txheeb xyuas, uas yog, los ntawm lub voj voog teeb liab kom hloov nws mus rau hauv lub teeb liab hluav taws xob tus qauv, tso tawm mus rau qhov txuas tso zis.
Raws li lub hom phiaj thiab daim ntawv ntawm cov zis ntawm lub kaw lus nrhiav pom, qhov txuas tso zis yog feem ntau yog cov khoom siv tso saib thiab kaw suab, cov ntaub ntawv sib txuas lus interface thiab cov khoom siv tswj.
Lub voj voog tswj lub teeb liab ntawm lub sensor yog txiav txim siab los ntawm hom sensor thiab qhov yuav tsum tau ua rau lub teeb liab tso zis. Cov sensor sib txawv muaj cov teeb liab tso zis sib txawv. Cov zis ntawm lub sensor tswj lub zog yog qhov hloov pauv ntawm cov yam ntxwv hluav taws xob, uas yuav tsum tau hloov mus rau hauv qhov hloov pauv voltage los ntawm lub voj voog choj, thiab qhov tso zis teeb liab voltage ntawm lub voj voog choj yog me me, thiab qhov voltage hom dav dav yog loj, uas yuav tsum tau ua kom nrov dua los ntawm lub cuab yeej amplifier. Cov teeb liab voltage thiab tam sim no tso zis los ntawm lub sensor hloov pauv zog feem ntau muaj cov teeb liab suab nrov loj. Lub voj voog lim dej yog qhov xav tau los rho tawm cov teeb liab muaj txiaj ntsig thiab lim tawm cov teeb liab suab nrov tsis muaj txiaj ntsig. Ntxiv mus, qhov amplitude ntawm cov teeb liab voltage tso zis los ntawm lub sensor zog dav dav yog qis heev, thiab nws tuaj yeem raug ua kom nrov dua los ntawm lub cuab yeej amplifier.
Piv nrog rau lub tshuab hluav taws xob, qhov zaus ntawm lub tshuab photoelectric tau nce ntau qhov kev txiav txim siab ntawm qhov loj. Qhov kev hloov pauv no hauv qhov kev txiav txim siab zaus ua rau lub tshuab photoelectric muaj kev hloov pauv zoo hauv txoj kev paub thiab kev dhia zoo hauv kev ua haujlwm. Feem ntau pom tseeb hauv lub peev xwm nqa khoom, kev daws teeb meem kaum sab xis, kev daws teeb meem ntau yam thiab kev daws teeb meem spectral tau txhim kho zoo heev, yog li nws tau siv dav hauv cov teb ntawm channel, radar, kev sib txuas lus, kev taw qhia meej, kev navigation, kev ntsuas thiab lwm yam. Txawm hais tias cov qauv tshwj xeeb ntawm lub tshuab photoelectric siv rau cov xwm txheej no sib txawv, lawv muaj ib qho tshwj xeeb, uas yog, lawv txhua tus muaj qhov txuas ntawm transmitter, optical channel thiab optical receiver.
Feem ntau, cov tshuab photoelectric raug muab faib ua ob pawg: active thiab passive. Hauv cov tshuab photoelectric active, lub tshuab xa hluav taws xob feem ntau yog tsim los ntawm lub teeb (xws li laser) thiab lub modulator. Hauv cov tshuab photoelectric passive, lub tshuab xa hluav taws xob tso tawm cov hluav taws xob thermal los ntawm cov khoom uas raug sim. Cov channel optical thiab cov receiver optical zoo ib yam rau ob qho tib si. Qhov hu ua optical channel feem ntau yog hais txog huab cua, qhov chaw, hauv dej thiab fiber optical. Lub receiver optical yog siv los sau cov teeb liab optical thiab ua nws kom rov qab tau cov ntaub ntawv ntawm lub tshuab optical, suav nrog peb lub modules yooj yim.
Kev hloov pauv photoelectric feem ntau yog ua tiav los ntawm ntau yam khoom siv kho qhov muag thiab cov tshuab kho qhov muag, siv cov iav tiaj tus, cov qhov muag pom, cov iav lo ntsiab muag, cov prisms cone, polarizers, cov phaj nthwv dej, cov phaj code, grating, modulators, cov tshuab duab kho qhov muag, cov tshuab cuam tshuam kho qhov muag, thiab lwm yam, kom ua tiav qhov kev hloov pauv ntsuas mus rau hauv cov kev ntsuas kho qhov muag (amplitude, zaus, theem, lub xeev polarization, kev hloov pauv kev taw qhia, thiab lwm yam). Kev hloov pauv photoelectric yog ua tiav los ntawm ntau yam khoom siv hloov pauv photoelectric, xws li cov khoom siv nrhiav pom photoelectric, cov khoom siv koob yees duab photoelectric, cov khoom siv thermal photoelectric thiab lwm yam.
