Ib feem ntawm ib qho
1, kev kuaj pom tau dhau los ntawm qee txoj kev siv lub cev, paub qhov txawv ntawm cov ntsuas ntsuas tau yog qee yam, txhawm rau txiav txim siab yog tsim nyog lossis tus naj npawb ntawm cov tsis muaj. Cov txheej txheem ntawm kev sib piv kom muaj nuj nqis ntsuas nrog cov txheej txheem ntawm tib yam, txiav txim siab ntau ntawm pab pawg ntsuas ntsuas, thiab qhia txog qhov no ntau tshaj plaws.
Hauv teb ntawm cov khoom siv tshuab thiab kev tshawb nrhiav cov khoom lag luam tsis tau, tab sis kuj tseem nyob rau cov txheej txheem ua tiav, tab sis tswj thiab tswj cov khoom kom nws ua kom zoo tshaj plaws Cov Txiaj Ntsig Xaiv los ntawm cov neeg, nws yog ib qho tsim nyog los tshawb xyuas thiab ntsuas qhov loj me thiab hloov ntawm ntau yam tsis tau txhua lub sijhawm. Qhov no thev naus laus zis ntawm lub sijhawm tiag tiag thiab kev ntsuas ntawm cov txheej txheem ntau lawm thiab txav cov khoom kuj tseem hu ua kev soj ntsuam kev tshuaj xyuas thev naus laus zis.
Muaj ob hom kev ntsuas: ntsuas ncaj qha thiab ntsuas kev ua tsis ncaj
Kev ntsuas ncaj qha yog ntsuas ntsuas ntsuas tus nqi ntawm lub ntsuas kub nyeem tsis muaj kev ntsuas kub, uas siv ntau rau kev ntsuas hluav taws xob
Kev ntsuas tsis ncaj ncees yog ntsuas tau ntau lub cev nqaij daim tawv uas cuam tshuam tau raug ntsuas, thiab suav xam cov ntsuas ntsuas los ntawm kev ua haujlwm. Piv txwv li, lub hwj chim P muaj feem cuam tshuam nrog voltage v thiab tam sim no kuv, uas yog, p = piv txwv los ntsuas ntsuas qhov ntsuas hluav taws xob thiab tam sim no.
Kev ntsuas ncaj qha yog yooj yim thiab yooj yim, thiab feem ntau siv hauv kev coj ua. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv qhov twg ntsuas ntsuas ncaj qha yog tsis yooj yim yog qhov tsis yooj yim lossis ntsuas ntsuas ncaj qha, tsis yog kev ntsuas ncaj qha.
Lub tswvyim ntawm photoelectric sensor thiab sensor
Cov nuj nqi ntawm lub sensor yog los hloov cov hluav taws xob tsis siv hluav taws xob rau cov hluav taws xob muaj txiaj ntsig, uas yog qhov tseem ceeb ntawm cov khoom hluav taws xob tsis-hluav taws xob kom muaj nuj nqis. Nyob rau hauv cov txheej txheem kev tshuaj xyuas thiab tswj, lub sensor yog qhov tseem ceeb hloov dua siab tshiab. Los ntawm lub zog taw tes pom, lub sensor tuaj yeem faib ua ob hom: ib qho yog lub zog tswj sensor, tseem hu ua lub peev xwm nquag; Lwm tus yog lub zog hloov siab hloov siab hloov siab sensor, tseem hu ua kev nkag siab sensor. Zog tswj sensor yog hais txog lub sensor yuav ntsuas mus rau cov kev hloov pauv hluav taws xob (muaj peev xwm ntsuas tau hloov chaw zoo rau cov kev hloov pauv, tuaj yeem hloov pauv hloov mus rau hauv voltage, hloov pauv tam sim no. Lub zog hloov dua siab tshiab sensor tuaj yeem hloov ntsuas ntsuas ntsuas mus rau qhov hloov pauv ntawm voltage thiab tam sim no, tsis muaj kev paub sab nraud.
Feem ntau, cov tsis yog hluav taws xob kom muaj nuj nqis tsis yog hom khoom siv hluav taws xob tsis zoo, uas cov ntsuas hluav taws xob tau hloov mus rau qhov tsis-hluav taws xob kom muaj ntau ntsuas rau hauv Tsis-hluav taws xob kom muaj nuj nqis uas lub sensor tuaj yeem tau txais thiab hloov. Cov khoom sib xyaw lossis cov cuab yeej uas tuaj yeem hloov ntsuas hluav taws xob tsis muaj hluav taws xob yog qhov ntsuas. Piv txwv li, thaum ntsuas hluav taws xob nrog cov tshuaj tiv thaiv kab mob siab, nws yog qhov tsim nyog hloov lub siab rau hauv lub zog elastic rau hauv lub zog elaste, thiab lub ntsuas cua sib hloov pauv lub zog rau hauv a hloov pauv tsis kam. Ntawm no yog cov koob tshuaj lom zem yog lub sensor, thiab tus Elastic keeb yog lub sensor. Ob lub sensor thiab lub sensor tuaj yeem hloov ntsuas hluav taws xob tsis yog siv hluav taws xob tsis muaj hluav taws xob, thiab lub ntsuas hluav taws xob ntsuas cov hluav taws xob uas tsis muaj hluav taws xob.
2, Photoelectric SensorYog ua raws li cov teeb meem photoelectric, lub teeb liab teeb liab, siv hluav taws xob siv tsis siv neeg, Aerospace thiab xov tooj cua thiab lwm daim teb.
Photoelectric sensors feem ntau yog suav nrog photodiodes, phototresistors CDs, Photocoupric, tau txais cov photocells, luam duab thiab cov duab sensors. Ib lub rooj ntawm cov tsiaj loj yog qhia hauv daim duab hauv qab no. Hauv cov ntawv thov siv, nws yog ib qho tsim nyog los xaiv lub ntsuas tsim nyog kom ua tiav cov nyhuv xav tau. Tus xaiv xaiv dav dav yog:Kev Ntsuas Cov Khoom Kub Ceev-CeevCircuit Court, ntau thaj tsam ntawm Illuminance Meter, ultra-siab-ceev-ceev-ceev liaser laser sensor yuav tsum xaiv photodiode; Txoj kev siv tshuaj txhuam mem tes yooj yim ntawm ob peb txhiab hertz thiab cov pulse-ceev mem tes Phoulthelectric hloov nyob rau hauv cov yooj yim Circuit Court yuav tsum xaiv lub phototransistor; Txawm hais tias qhov lus teb ceev yog qeeb, cov tsis kam choj nrog kev ua tau zoo, lub ntsuas hluav taws xob uas muaj zog nrog lub zog ntawm lub teeb yuav tsum xaiv CDs thiab PBS cov ntsiab lus photensensitive; Cov encoders egoders, ceev sensors thiab ultra-kev kub ceev lasasre sensors yuav tsum tau sib xyaw ua ke photoelectric.
